Galaxy S5 vs iPhone 5s - specs comparison; [Tech Review]
The iPhone 5s is considerably smaller and lighter than the Galaxy S5
With only a few weeks to go until Samsung's new flagship smartphone, the Galaxy S5 arrives, we've been crunching the numbers to see how it stacks up against the current crop of high-end handsets from other manufacturers. This week it's Apple's turn, as we compare the Galaxy S5 to the venerable iPhone 5s.
This is purely a specification comparison, highlighting the differences as they stand. We've included benchmark figures where we have them for Samsung's (still unreleased) handset to highlight any differences in performance. Until we get the Samsung Galaxy S5 in for a full review, however, it's impossible to judge things like screen quality, battery life and camera image quality. We'll be waiting until early April, when the Galaxy S5 officially launches, to deliver our final verdict. In the meantime you can decide whether the S5 will be worth waiting for, based on its specs, or whether you should pick up an iPhone 5S on contract today.
Materials: Apple has always been top when it comes to smartphone design and the iPhone 5s is no different. The iPhone 5s is made from anodized aluminium with diamond cut chamfered edges. It is available in gold, silver and grey. The Galaxy S5 has dimpled soft-touch plastic on the back, which gives it more grip. The plain black finish on the front looks stylish, too, although the silver metal effect trim around the edges remains. Unfortunately the handset is still made from plastic, rather than metal.
Both phones use Corning Gorilla Glass to protect the panel from scratches.
Resolution: The iPhone 5s has a screen resolution of 1,136x640 - an odd size which is a relic of older iOS devices. That means it is unable to play Full HD video, or even 720p footage at its native resolution, but a 377ppi pixel density means it is still impossible to see individual pixels from an average viewing distance.
The Galaxy S5 has a 1,920x1,080 Full HD resolution display, with a pixel density of 432PPI - despite the larger screen, the pixels are packed in more tightly than on the iPhone. It can play Full HD video at its native resolution, without having to downscale the picture in software.
Screen technology: Apple has always used LCD technology in its iPhones, which is able to produce significantly brighter images than competing technologies. We measured the iPhone 5s' peak brightness at a massive 505cd/m2, which is almost double that of Samsung's current generation Galaxy S4 - simply put, the iPhone 5s is brighter and produces whiter whites.
Samsung has used AMOLED screen technology in almost all of its flagship smartphones, and the Galaxy S5 is no exception. It has several advantages over LCD technology; individual pixels can be turned off when displaying absolute black images, so AMOLED screens have use less power when displaying them. Contrast ratios are significantly higher than LCD screens too.
The Galaxy S5 arranges its sub pixels in a pentile arrangement, interleaving green pixels between alternating red and blue pixels, whereas the iPhone 5s uses three sub-pixels (red, green and blue) for every pixel. This arguably means the iPhone doesn't need as high a resolution to make text and images look as sharp as the Galaxy S5, but in practice we think the Galaxy S5 looks sharper.
Processor: The iPhone 5s has an ARM v8-based 1.3GHz dual-core processor. This translates to an excellent score of 416ms in the SunSpider JavaScript test. The Galaxy S5 has a Snapdragon 801 processor running at 2.5GHz, which translates to speedy benchmark scores. In the SunSpider JavaScript test, the S5 completed the benchmark in 408ms. Graphics: The iPhone 5s has a PowerVR G6430 GPU. It is one of the best performing phones we’ve ever tested, maxing out both the 3D Mark Ice Storm Standard and Extreme Tests. It scored a very impressive 14,506 in the Ice Storm Unlimited test. The Galaxy S5 has a faster Adreno 330 GPU, which scores 18,438 in the same test. This makes it significantly faster when it comes to games.
Memory: Apple has included just 1GB of RAM in the iPhone 5s, but despite the low number that’s still more than adequate. Samsung has bettered Apple by sticking 2GB of RAM into the Galaxy S5.
Storage: There are three versions of the iPhone 5s – 16GB, 32GB and 64GB. By comparison the Galaxy S5 only comes in 16GB and 32GB versions, with no 64GB version planned at launch. It does at least have a microSD card slot, which supports up to 128GB cards.
Battery: The combination of the new processor, M7 motion process and a large 1,560mAh battery all mean that the iPhone 5S has excellent battery life. At half brightness with Wi-Fi turned off, our iPhone 5S lasted 14h 31m in our video playback test. The Galaxy S5 has a large 2,800mAh battery. Samsung says the S5 should manage 21 hours of 3G talk time from a single charge, but that's unlikely to account for the screen being on.
From the specs, the S5 (right) has more raw pixels than the iPhone 5s (left), but low light performance remains to be seen
On paper, the Galaxy S5 has a better front-facing camera - it uses a two megapixel sensor that can record video chat in 1080p at 30fps, compared to the 1.2-megapixel webcam in the iPhone 5s which can only manage 720p FaceTime video at 30fps
Apple was the first manufacturer to add a fingerprint sensor to a smartphone, fitting a TouchID sensor to the iPhone 5s. It can be used to unlock the phone, or confirm payment when making purchases on the App store, but no other apps support it yet because Apple hasn't made the API public. The Galaxy S5 now has its own fingerprint sensor, which is built into the home button. Rather than press and hold, you have to swipe your finger across the button to authorise PayPal transactions, protect files or folders and unlock the handset.
The Galaxy S5 is heavily targeted towards fitness, with ANT+ support for connecting a heart rate monitor or pedometer, and a heart rate sensor built into the back of the phone. It is also water- and dust-resistant. It is also compatible with Samsung's wearable range, including the original Galaxy Gear, new Gear 2 and Gear 2 Neo, and Gear Fit smart band.
There are too many differences between the two operating systems to go into here - for a more detailed breakdown of the features and issues with each one, read our iOS and Android reviews.
Samsung has moved from standard micro USB to a micro USB3 port on the Galaxy S5, but Apple uses its own proprietary Lightning connector. Both phones use the newer, smaller nano SIM standard, which Apple introduced with the iPhone 5.

SIZE AND WEIGHT
Dimensions: The iPhone 5s looks tiny compared to most smartphones. It weighs 112g and measures 123.8 x 58.6 x 7.6mm. The Galaxy S5 is considerably larger and heavier, weighing 145g and measuring 73x142x8.1mm.Materials: Apple has always been top when it comes to smartphone design and the iPhone 5s is no different.

The plain black finish on the front looks stylish, too, although the silver metal effect trim around the edges remains. Unfortunately the handset is still made from plastic, rather than metal.
SCREEN
Screen size: The iPhone 5s has a 4in display, which is beginning to look very small when held side-by-side with big-screen Android devices. The 16:9 aspect ratio means it's tall but thin, so your thumb can comfortably reach from the bottom left corner all the way up to the top right. The bezels at either side are a rather slim 4mm thick, meaning 60.6% of the entire front surface is comprised of screen.
The Galaxy S5, meanwhile, has a massive 5.1in screen which makes the iPhone 5s look tiny by comparison. The exterior bezels are slightly thinner too, at 3mm each side. The aspect ratio is also 16:9, but because of the size difference people with smaller hands may struggle to reach the very top of the screen with one hand.Both phones use Corning Gorilla Glass to protect the panel from scratches.
Resolution: The iPhone 5s has a screen resolution of 1,136x640 - an odd size which is a relic of older iOS devices. That means it is unable to play Full HD video, or even 720p footage at its native resolution, but a 377ppi pixel density means it is still impossible to see individual pixels from an average viewing distance.

Samsung says the S5 should manage 21 hours of 3G talk time from a single charge, but that's unlikely to account for the screen being on.
CAMERA
The iPhone 5s has a 8-megapixel, back side illuminated (BSI) rear camera sensor, which is paired with a dual LED flash. It captures 3264 x 2448 resolution stills and records Full HD video at 30fps, with a slow motion function. The 1/3in sensor has 1.5µm pixels, which are significantly larger than most smartphone cameras to capture more light information. The Galaxy S5 has a 1/2.6in sensor with 1.241µm pixels. Despite having a larger 16-megapixel sensor, cramming more pixels into a smaller surface area won't necessarily increase picture quality over the iPhone. The S5's camera also uses the new ISOCELL sensor technology, which reduces the crop factor of the final image and improves dynamic range by preventing light leaking from one pixel to another. It shoots 4,640x3,480 (16.15-megapixel) stills and records 1080p video at 60fps. It is also able to record Ultra HD (4K) 3,840x2,160 video at 30fps and shoot video in high definition.From the specs, the S5 (right) has more raw pixels than the iPhone 5s (left), but low light performance remains to be seen
On paper, the Galaxy S5 has a better front-facing camera - it uses a two megapixel sensor that can record video chat in 1080p at 30fps, compared to the 1.2-megapixel webcam in the iPhone 5s which can only manage 720p FaceTime video at 30fps

It is also water- and dust-resistant. It is also compatible with Samsung's wearable range, including the original Galaxy Gear, new Gear 2 and Gear 2 Neo, and Gear Fit smart band.
SOFTWARE
One of the biggest differences between the Galaxy S5 and the iPhone 5s isn't physical - it's in the software. The iPhone runs Apple's iOS operating system, while the Galaxy 5S uses a heavily customised version of Apple's Android.
In its first few years, Android had significantly fewer apps than iOS, but now virtually every major brand or developer makes their apps simultaneously for both platforms. There are few, if any platform exclusives any more, and Android has never been easier to use, so if you aren't familiar with either operating system, software is no longer a reason to choose one phone over the other.There are too many differences between the two operating systems to go into here - for a more detailed breakdown of the features and issues with each one, read our iOS and Android reviews.
4G and Wi-Fi
Both the Galaxy S5 and iPhone 5s support all major 2G, 3G and 4G LTE frequency bands, although the S5 supports the faster LTE Category 4 and LTE-Advanced modes while the iPhone 5s makes do with LTE Category 3. When it first launched the iPhone 5S unable to use O2's 4G network, but this was a certification issue and not a hardware problem - it is now compatible with every 4G network here in the UK, and we expect the S5 to be the same when it arrives. The iPhone 5s only supports 802.11n Wi-Fi, whereas the Galaxy S5 supports the faster 802.11ac version. They both support Bluetooth 4.0 and GPS geo-location, but the Galaxy S5 has both NFC and an Infra-red blaster for controlling TVs or other home cinema equipment.Samsung has moved from standard micro USB to a micro USB3 port on the Galaxy S5, but Apple uses its own proprietary Lightning connector. Both phones use the newer, smaller nano SIM standard, which Apple introduced with the iPhone 5.

BlackBerry Q10 Review – The Best Option for BlackBerry Fans
BlackBerry Q10 Review – The Best Option for BlackBerry Fans
The BlackBerry Q10 is the second BlackBerry 10 device to launch in the United States and, thanks to its QWERTY keyboard, it seems to be the device that BlackBerry fans have been waiting for. It offers a slightly low-res and awkwardly small screen, though that’s at the cost of the keyboard. Is that keyboard enough for us to recommend the phone over other devices? Or is this just the next best thing for BlackBerry fans? We’ll discuss all of that and more in our review.
HARDWARE
The Q10 hardware calls back the days of the BlackBerry Bold, though
it’s not nearly as premium feeling. It’s crafted entirely out of plastic
and doesn’t have any faux metal accents or anything that screams “first
class.” It also ditches the trackball/trackpad of the older BlackBerry
devices in favor of a touchscreen display that works pretty well, though
we still really miss the hardware buttons. We weren’t alone, either,
everyone we showed the phone to asked where the hardware keys for the
send/end buttons were.
The BlackBerry Q10 measures 4.71-inches x 2.63 inches x 0.41 inches, which makes it one of the more pocketable phones we’ve reviewed recently. It also weighs in at 4.90 ounces, which is relatively light but gives it enough bulk that it feels solid.
Under the hood the Q10 has a 1.5GHz dual-core Snapdragon S4 Plus processor, 2GB of RAM, 16GB of expandable storage using a microSD card slot, an 8-megapixel camera sensor and a 2-megapixel front-facing camera.
Its 3.1-inch display is certainly small, especially compared to Android devices with screens more than an inch larger, and it has a 720 x 720-pixel resolution. The screen is easy to view under direct sunlight, despite its SuperAMOLED technology, though the resolution was strikingly low given our recent adjustment to 1080p smartphones.

There’s a microUSB and HDMI-out port on the left of the phone, a
3.5mm headphone jack and power button on the top and volume toggle keys
on the right. The keyboard brought back fond memories of when I used to
use a BlackBerry daily, and I loved firing off longer emails from it. I
found that I adjusted back to hardware keyboard almost immediately and
appreciated how accurately I was able to type.
Unfortunately, however, the keyboard wasn’t enough to keep me hanging around the BlackBerry. That’s mainly because of the software offering.
SOFTWARE
Unfortunately, however, the keyboard wasn’t enough to keep me hanging around the BlackBerry. That’s mainly because of the software offering.
SOFTWARE
The Q10 runs BlackBerry 10, which still leaves a lot to be desired. We covered the operating system in-depth in our Z10 review,
so we’ll stick to a few basics here. Navigation is achieved almost
entirely using the touchscreen and gestures. BlackBerry Hub is a
container for all of your alerts, including email, Facebook, text
messages, Twitter and BBM notifications. Navigation around the software
is smooth and rarely laggy, thanks largely in part to the processor and
RAM.
The problem with the software resides in the ecosystem. BlackBerry 10 still lags terribly behind Android and iOS when it comes to app selection. The company promises Pandora is still coming soon, though that’s not enough reason to stick around. The maps software is awful, Instagram, Vine, Netflix and dozens of other popular applications are not available for the platform. You can port Android apps to the Q10, though they don’t all work properly.
Overall, BlackBerry fans will be pleased by the new features BlackBerry 10 offers, but I don’t think a lot of people are going to ditch iOS or Android simply for the BlackBerry Q10’s keyboard. It’s a shame, too, because with more apps I’d be happy to ditch either platform for the full QWERTY.
We won’t ding the Q10 too hard on BlackBerry 10 largely because consumers should have an idea what they’re getting into at this point. From a hardware perspective the device is compelling enough for anyone upgrading from a Curve or Bold.
CAMERA
FROM BLACKBERRY PRODUCER
We largely think most consumers know if this phone is for them or not before they even walk in the store. BlackBerry fans, and we mean those that are carrying one right now, will really appreciate the upgrade in almost every regard.
Still, the Q10 doesn’t hold a candle to the HTC One, Galaxy S4 or iPhone 5, no matter how you look at it. The keyboard is fantastic, but when we can’t download apps and get stuck with a mediocre camera the trade-offs are hard to stick with.
The Q10 itself is a great phone, lovely in nearly every way, but it’s meant for BlackBerry fans and not for all consumers.

CAMERA
The Q10 has the same 8-megapixel camera as the BlackBerry Z10. While
it has some neat features that allows you to choose the best photo, the
actual quality of the pictures left a lot to be desired. It’s just not
on the same level with pictures we shoot with the Galaxy S4’s
13-megapixel camera, the HTC One’s 4-Ultrapixel camera or even the
camera on the iPhone 5.
Sure, that aforementioned TimeShift feature is neat, but you need to activate it and then move through each image to pick the best one. HTC and Samsung phones have burst modes, too, and even rapid fire options that enable the same type of selection. Is it the best camera on a BlackBerry? Sure, I have no doubt that the Z10 and Q10 cameras are better than the others, they’re just not the best on the market.
The Q10 can also record 1080p video, but again it left me unimpressed as the images. It looked great when played back on the device’s display, however.
BATTERY LIFE
We were able to get a full day’s use out of the battery and, under light usage, we wouldn’t be surprised to see it last about a day and a half. This is likely because the phone has a smaller display, which is typically one of the biggest drains on battery life. In our usage scenarios Jon Rettinger and I (we both had units) generally kept the phone off its charger from about 7a.m. until 11p.m. checking two email accounts, browsing the web, reading Twitter and playing a game or two. At the end of the day we usually saw between 20-30 percent of the battery left.

TECHNOLOGY
Technology (from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia[1]) is the making, modification, usage, and knowledge of tools, machines, techniques, crafts, systems, and methods of organization, in order to solve a problem, improve a pre-existing solution to a problem, achieve a goal, handle an applied input/output relation or perform a specific function. It can also refer to the collection of such tools, including machinery, modifications, arrangements and procedures. Technologies significantly affect human as well as other animal species' ability to control and adapt to their natural environments. The term can either be applied generally or to specific areas: examples include construction technology, medical technology, and information technology.
By the mid 20th century, humans had achieved a mastery of technology sufficient to leave the atmosphere of the Earth for the first time and explore space.
Technology has affected society and its surroundings in a number of ways. In many societies, technology has helped develop more advanced economies (including today's global economy) and has allowed the rise of a leisure class. Many technological processes produce unwanted by-products, known as pollution, and deplete natural resources, to the detriment of Earth's environment. Various implementations of technology influence the values of a society and new technology often raises new ethical questions. Examples include the rise of the notion of efficiency in terms of human productivity, a term originally applied only to machines, and the challenge of traditional norms.
Philosophical debates have arisen over the present and future use of technology in society, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and similar movements criticise the pervasiveness of technology in the modern world, opining that it harms the environment and alienates people; proponents of ideologies such as transhumanism and techno-progressivism view continued technological progress as beneficial to society and the human condition. Indeed, until recently, it was believed that the development of technology was restricted only to human beings, but recent scientific studies indicate that other primates and certain dolphin communities have developed simple tools and learned to pass their knowledge to other generations.
Definition and usage
Dictionaries and scholars have offered a variety of definitions. The Merriam-Webster dictionary offers a definition of the term: "the practical application of knowledge especially in a particular area" and "a capability given by the practical application of knowledge".[7] Ursula Franklin, in her 1989 "Real World of Technology" lecture, gave another definition of the concept; it is "practice, the way we do things around here".[8] The term is often used to imply a specific field of technology, or to refer to high technology or just consumer electronics, rather than technology as a whole.[9] Bernard Stiegler, in Technics and Time, 1, defines technology in two ways: as "the pursuit of life by means other than life", and as "organized inorganic matter."[10]
Technology can be most broadly defined as the entities, both material and immaterial, created by the application of mental and physical effort in order to achieve some value. In this usage, technology refers to tools and machines that may be used to solve real-world problems. It is a far-reaching term that may include simple tools, such as a crowbar or wooden spoon, or more complex machines, such as a space station or particle accelerator. Tools and machines need not be material; virtual technology, such as computer software and business methods, fall under this definition of technology.[11]
The word "technology" can also be used to refer to a collection of techniques. In this context, it is the current state of humanity's knowledge of how to combine resources to produce desired products, to solve problems, fulfill needs, or satisfy wants; it includes technical methods, skills, processes, techniques, tools and raw materials. When combined with another term, such as "medical technology" or "space technology", it refers to the state of the respective field's knowledge and tools. "State-of-the-art technology" refers to the high technology available to humanity in any field.
Science, engineering and technology
The distinction between science, engineering and technology is not always clear. Science is the reasoned investigation or study of phenomena, aimed at discovering enduring principles among elements of the phenomenal world by employing formal techniques such as the scientific method.[14] Technologies are not usually exclusively products of science, because they have to satisfy requirements such as utility, usability and safety.Engineering is the goal-oriented process of designing and making tools and systems to exploit natural phenomena for practical human means, often (but not always) using results and techniques from science. The development of technology may draw upon many fields of knowledge, including scientific, engineering, mathematical, linguistic, and historical knowledge, to achieve some practical result.
Technology is often a consequence of science and engineering — although technology as a human activity precedes the two fields. For example, science might study the flow of electrons in electrical conductors, by using already-existing tools and knowledge. This new-found knowledge may then be used by engineers to create new tools and machines, such as semiconductors, computers, and other forms of advanced technology. In this sense, scientists and engineers may both be considered technologists; the three fields are often considered as one for the purposes of research and reference.[15]
The exact relations between science and technology in particular have been debated by scientists, historians, and policymakers in the late 20th century, in part because the debate can inform the funding of basic and applied science. In the immediate wake of World War II, for example, in the United States it was widely considered that technology was simply "applied science" and that to fund basic science was to reap technological results in due time. An articulation of this philosophy could be found explicitly in Vannevar Bush's treatise on postwar science policy, Science—The Endless Frontier: "New products, new industries, and more jobs require continuous additions to knowledge of the laws of nature ... This essential new knowledge can be obtained only through basic scientific research." In the late-1960s, however, this view came under direct attack, leading towards initiatives to fund science for specific tasks (initiatives resisted by the scientific community). The issue remains contentious—though most analysts resist the model that technology simply is a result of scientific research.[16][17]
History

Paleolithic (2.5 million YA – 10,000 BC)
Further information: Outline of prehistoric technology
The use of tools by early humans was partly a process of discovery and of evolution. Early humans evolved from a species of foraging hominids which were already bipedal,[18] with a brain mass approximately one third of modern humans.[19] Tool use remained relatively unchanged for most of early human history. Approximately 50,000 years ago, the use of tools and complex set of behaviors emerged, believed by many archaeologists to be connected to the emergence of fully modern language.[20]Stone tools
Human ancestors have been using stone and other tools since long before the emergence of Homo sapiens approximately 200,000 years ago.[21] The earliest methods of stone tool making, known as the Oldowan "industry", date back to at least 2.3 million years ago,[22] with the earliest direct evidence of tool usage found in Ethiopia within the Great Rift Valley, dating back to 2.5 million years ago.[23] This era of stone tool use is called the Paleolithic, or "Old stone age", and spans all of human history up to the development of agriculture approximately 12,000 years ago.To make a stone tool, a "core" of hard stone with specific flaking properties (such as flint) was struck with a hammerstone. This flaking produced a sharp edge on the core stone as well as on the flakes, either of which could be used as tools, primarily in the form of choppers or scrapers.[24] These tools greatly aided the early humans in their hunter-gatherer lifestyle to perform a variety of tasks including butchering carcasses (and breaking bones to get at the marrow); chopping wood; cracking open nuts; skinning an animal for its hide; and even forming other tools out of softer materials such as bone and wood.[25]
The earliest stone tools were crude, being little more than a fractured rock. In the Acheulian era, beginning approximately 1.65 million years ago, methods of working these stone into specific shapes, such as hand axes emerged. The Middle Paleolithic, approximately 300,000 years ago, saw the introduction of the prepared-core technique, where multiple blades could be rapidly formed from a single core stone.[24] The Upper Paleolithic, beginning approximately 40,000 years ago, saw the introduction of pressure flaking, where a wood, bone, or antler punch could be used to shape a stone very finely.[26]
Fire
Main article: Control of fire by early humans
The discovery and utilization of fire, a simple energy source with many profound uses, was a turning point in the technological evolution of humankind.[27] The exact date of its discovery is not known; evidence of burnt animal bones at the Cradle of Humankind suggests that the domestication of fire occurred before 1,000,000 BC;[28] scholarly consensus indicates that Homo erectus had controlled fire by between 500,000 BC and 400,000 BC.[29][30] Fire, fueled with wood and charcoal,
allowed early humans to cook their food to increase its digestibility,
improving its nutrient value and broadening the number of foods that
could be eaten.[31]Clothing and shelter
Other technological advances made during the Paleolithic era were clothing and shelter; the adoption of both technologies cannot be dated exactly, but they were a key to humanity's progress. As the Paleolithic era progressed, dwellings became more sophisticated and more elaborate; as early as 380,000 BC, humans were constructing temporary wood huts.[32][33] Clothing, adapted from the fur and hides of hunted animals, helped humanity expand into colder regions; humans began to migrate out of Africa by 200,000 BC and into other continents, such as Eurasia.[34]Neolithic through classical antiquity (10,000 BC – 300 AD)
Man's technological ascent began in earnest in what is known as the Neolithic period ("New stone age"). The invention of polished stone axes was a major advance because it allowed forest clearance on a large scale to create farms. The discovery of agriculture allowed for the feeding of larger populations, and the transition to a sedentist lifestyle increased the number of children that could be simultaneously raised, as young children no longer needed to be carried, as was the case with the nomadic lifestyle. Additionally, children could contribute labor to the raising of crops more readily than they could to the hunter-gatherer lifestyle.[35][36]With this increase in population and availability of labor came an increase in labor specialization.[37] What triggered the progression from early Neolithic villages to the first cities, such as Uruk, and the first civilizations, such as Sumer, is not specifically known; however, the emergence of increasingly hierarchical social structures, the specialization of labor, trade and war amongst adjacent cultures, and the need for collective action to overcome environmental challenges, such as the building of dikes and reservoirs, are all thought to have played a role.[38]
Metal tools
Continuing improvements led to the furnace and bellows and provided the ability to smelt and forge native metals (naturally occurring in relatively pure form).[39] Gold, copper, silver, and lead, were such early metals. The advantages of copper tools over stone, bone, and wooden tools were quickly apparent to early humans, and native copper was probably used from near the beginning of Neolithic times (about 8000 BC).[40] Native copper does not naturally occur in large amounts, but copper ores are quite common and some of them produce metal easily when burned in wood or charcoal fires. Eventually, the working of metals led to the discovery of alloys such as bronze and brass (about 4000 BC). The first uses of iron alloys such as steel dates to around 1400 BC.Energy and transport
Meanwhile, humans were learning to harness other forms of energy. The earliest known use of wind power is the sailboat.[41] The earliest record of a ship under sail is shown on an Egyptian pot dating back to 3200 BC.[42] From prehistoric times, Egyptians probably used the power of the Nile annual floods to irrigate their lands, gradually learning to regulate much of it through purposely built irrigation channels and 'catch' basins. Similarly, the early peoples of Mesopotamia, the Sumerians, learned to use the Tigris and Euphrates rivers for much the same purposes. But more extensive use of wind and water (and even human) power required another invention.According to archaeologists, the wheel was invented around 4000 B.C. probably independently and nearly-simultaneously in Mesopotamia (in present-day Iraq), the Northern Caucasus (Maykop culture) and Central Europe. Estimates on when this may have occurred range from 5500 to 3000 B.C., with most experts putting it closer to 4000 B.C. The oldest artifacts with drawings that depict wheeled carts date from about 3000 B.C.; however, the wheel may have been in use for millennia before these drawings were made. There is also evidence from the same period of time that wheels were used for the production of pottery. (Note that the original potter's wheel was probably not a wheel, but rather an irregularly shaped slab of flat wood with a small hollowed or pierced area near the center and mounted on a peg driven into the earth. It would have been rotated by repeated tugs by the potter or his assistant.) More recently, the oldest-known wooden wheel in the world was found in the Ljubljana marshes of Slovenia.[43]
The invention of the wheel revolutionized activities as disparate as transportation, war, and the production of pottery (for which it may have been first used). It did not take long to discover that wheeled wagons could be used to carry heavy loads and fast (rotary) potters' wheels enabled early mass production of pottery. But it was the use of the wheel as a transformer of energy (through water wheels, windmills, and even treadmills) that revolutionized the application of nonhuman power sources.
Medieval and modern history (300 AD – present)
Main articles: Medieval technology, Renaissance technology, Industrial Revolution, Second Industrial Revolution, Productivity improving technologies (historical), and Information Technology
Innovations continued through the Middle Ages with innovations such as silk, the horse collar and horseshoes in the first few hundred years after the fall of the Roman Empire. Medieval technology saw the use of simple machines (such as the lever, the screw, and the pulley) being combined to form more complicated tools, such as the wheelbarrow, windmills and clocks. The Renaissance brought forth many of these innovations, including the printing press (which facilitated the greater communication of knowledge), and technology became increasingly associated with science,
beginning a cycle of mutual advancement. The advancements in technology
in this era allowed a more steady supply of food, followed by the wider
availability of consumer goods.Starting in the United Kingdom in the 18th century, the Industrial Revolution was a period of great technological discovery, particularly in the areas of agriculture, manufacturing, mining, metallurgy and transport, driven by the discovery of steam power. Technology later took another step with the harnessing of electricity to create such innovations as the electric motor, light bulb and countless others. Scientific advancement and the discovery of new concepts later allowed for powered flight, and advancements in medicine, chemistry, physics and engineering. The rise in technology has led to the construction of skyscrapers and large cities whose inhabitants rely on automobiles or other powered transit for transportation. Communication was also greatly improved with the invention of the telegraph, telephone, radio and television. The late 19th and early 20th centuries saw a revolution in transportation with the invention of the steam-powered ship, train, airplane, and automobile.
The 20th century brought a host of innovations. In physics, the discovery of nuclear fission has led to both nuclear weapons and nuclear power. Computers were also invented and later miniaturized utilizing transistors and integrated circuits. The technology behind got called information technology, and these advancements subsequently led to the creation of the Internet, which ushered in the current Information Age. Humans have also been able to explore space with satellites (later used for telecommunication) and in manned missions going all the way to the moon. In medicine, this era brought innovations such as open-heart surgery and later stem cell therapy along with new medications and treatments. Complex manufacturing and construction techniques and organizations are needed to construct and maintain these new technologies, and entire industries have arisen to support and develop succeeding generations of increasingly more complex tools. Modern technology increasingly relies on training and education — their designers, builders, maintainers, and users often require sophisticated general and specific training. Moreover, these technologies have become so complex that entire fields have been created to support them, including engineering, medicine, and computer science, and other fields have been made more complex, such as construction, transportation and architecture.
Technology and philosophy
Technicism
Generally, technicism is a reliance or confidence in technology as a benefactor of society. Taken to extreme, technicism is the belief that humanity will ultimately be able to control the entirety of existence using technology. In other words, human beings will someday be able to master all problems and possibly even control the future using technology. Some, such as Stephen V. Monsma,[44] connect these ideas to the abdication of religion as a higher moral authority.Optimism
See also: Extropianism
Optimistic assumptions are made by proponents of ideologies such as transhumanism and singularitarianism, which view technological development
as generally having beneficial effects for the society and the human
condition. In these ideologies, technological development is morally
good. Some critics see these ideologies as examples of scientism and techno-utopianism and fear the notion of human enhancement and technological singularity which they support. Some have described Karl Marx as a techno-optimist.[45]Skepticism and critics of technology
See also: Luddite, Neo-luddism, Anarcho-primitivism, and Bioconservatism
On the somewhat skeptical side are certain philosophers like Herbert Marcuse and John Zerzan,
who believe that technological societies are inherently flawed. They
suggest that the inevitable result of such a society is to become
evermore technological at the cost of freedom and psychological health.Many, such as the Luddites and prominent philosopher Martin Heidegger, hold serious, although not entirely deterministic reservations, about technology (see "The Question Concerning Technology"[46]). According to Heidegger scholars Hubert Dreyfus and Charles Spinosa, "Heidegger does not oppose technology. He hopes to reveal the essence of technology in a way that 'in no way confines us to a stultified compulsion to push on blindly with technology or, what comes to the same thing, to rebel helplessly against it.' Indeed, he promises that 'when we once open ourselves expressly to the essence of technology, we find ourselves unexpectedly taken into a freeing claim.'[47]" What this entails is a more complex relationship to technology than either techno-optimists or techno-pessimists tend to allow.[48]
Some of the most poignant criticisms of technology are found in what are now considered to be dystopian literary classics, for example Aldous Huxley's Brave New World and other writings, Anthony Burgess's A Clockwork Orange, and George Orwell's Nineteen Eighty-Four. And, in Faust by Goethe, Faust's selling his soul to the devil in return for power over the physical world, is also often interpreted as a metaphor for the adoption of industrial technology. More recently, modern works of science fiction, such as those by Philip K. Dick and William Gibson, and films (e.g. Blade Runner, Ghost in the Shell) project highly ambivalent or cautionary attitudes toward technology's impact on human society and identity.
The late cultural critic Neil Postman distinguished tool-using societies from technological societies and, finally, what he called "technopolies," that is, societies that are dominated by the ideology of technological and scientific progress, to the exclusion or harm of other cultural practices, values and world-views.[49]
Darin Barney has written about technology's impact on practices of citizenship and democratic culture, suggesting that technology can be construed as (1) an object of political debate, (2) a means or medium of discussion, and (3) a setting for democratic deliberation and citizenship. As a setting for democratic culture, Barney suggests that technology tends to make ethical questions, including the question of what a good life consists in, nearly impossible, because they already give an answer to the question: a good life is one that includes the use of more and more technology.[50]
Nikolas Kompridis has also written about the dangers of new technology, such as genetic engineering, nanotechnology, synthetic biology and robotics. He warns that these technologies introduce unprecedented new challenges to human beings, including the possibility of the permanent alteration of our biological nature. These concerns are shared by other philosophers, scientists and public intellectuals who have written about similar issues (e.g. Francis Fukuyama, Jürgen Habermas, William Joy, and Michael Sandel).[51]
Another prominent critic of technology is Hubert Dreyfus, who has published books On the Internet and What Computers Still Can't Do.
Another, more infamous anti-technological treatise is Industrial Society and Its Future, written by Theodore Kaczynski (aka The Unabomber) and printed in several major newspapers (and later books) as part of an effort to end his bombing campaign of the techno-industrial infrastructure.
Appropriate technology
See also: Technocriticism and Technorealism
The notion of appropriate technology, however, was developed in the 20th century (e.g., see the work of E. F. Schumacher and of Jacques Ellul)
to describe situations where it was not desirable to use very new
technologies or those that required access to some centralized infrastructure or parts or skills imported from elsewhere. The eco-village movement emerged in part due to this concern.Technology and competitiveness
In 1983 a classified program was initiated in the US intelligence community to reverse the US declining economic and military competitiveness. The program, Project Socrates, used all source intelligence to review competitiveness worldwide for all forms of competition to determine the source of the US decline. What Project Socrates determined was that technology exploitation is the foundation of all competitive advantage and that the source of the US declining competitiveness was the fact that decision-making through the US both in the private and public sectors had switched from decision making that was based on technology exploitation (i.e., technology-based planning) to decision making that was based on money exploitation (i.e., economic-based planning) at the end of World War II.Technology is properly defined as any application of science to accomplish a function. The science can be leading edge or well established and the function can have high visibility or be significantly more mundane but it is all technology, and its exploitation is the foundation of all competitive advantage.
Technology-based planning is what was used to build the US industrial giants before WWII (e.g., Dow, DuPont, GM) and it what was used to transform the US into a superpower. It was not economic-based planning.
Project Socrates determined that to rebuild US competitiveness, decision making throughout the US had to readopt technology-based planning. Project Socrates also determined that countries like China and India had continued executing technology-based (while the US took its detour into economic-based) planning, and as a result had considerably advanced the process and were using it to build themselves into superpowers. To rebuild US competitiveness the US decision-makers needed to adopt a form of technology-based planning that was far more advanced than that used by China and India.
Project Socrates determined that technology-based planning makes an evolutionary leap forward every few hundred years and the next evolutionary leap, the Automated Innovation Revolution, was poised to occur. In the Automated Innovation Revolution the process for determining how to acquire and utilize technology for a competitive advantage (which includes R&D) is automated so that it can be executed with unprecedented speed, efficiency and agility.
Project Socrates developed the means for automated innovation so that the US could lead the Automated Innovation Revolution in order to rebuild and maintain the country's economic competitiveness for many generations.[52][53][54]
The use of basic technology is also a feature of other animal species apart from humans. These include primates such as chimpanzees, some dolphin communities,[55][56] and crows.[57][58] Considering a more generic perspective of technology as ethology of active environmental conditioning and control, we can also refer to animal examples such as beavers and their dams, or bees and their honeycombs.
The ability to make and use tools was once considered a defining characteristic of the genus Homo.[59] However, the discovery of tool construction among chimpanzees and related primates has discarded the notion of the use of technology as unique to humans. For example, researchers have observed wild chimpanzees utilising tools for foraging: some of the tools used include leaf sponges, termite fishing probes, pestles and levers.[60] West African chimpanzees also use stone hammers and anvils for cracking nuts,[61] as do capuchin monkeys of Boa Vista, Brazil.[62]
