What is Technology: Definition and 498 Discussions
Technology ("science of craft", from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia) is the sum of techniques, skills, methods, and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation. Technology can be the knowledge of techniques, processes, and the like, or it can be embedded in machines to allow for operation without detailed knowledge of their workings. Systems (e.g. machines) applying technology by taking an input, changing it according to the system's use, and then producing an outcome are referred to as technology systems or technological systems.
The simplest form of technology is the development and use of basic tools. The prehistoric invention of shaped stone tools followed by the discovery of how to control fire increased sources of food. The later Neolithic Revolution extended this, and quadrupled the sustenance available from a territory. The invention of the wheel helped humans to travel in and control their environment.
Developments in historic times, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale.
Technology has many effects. It 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. Innovations have always influenced the values of a society and raised new questions in the ethics of technology. Examples include the rise of the notion of efficiency in terms of human productivity, and the challenges of bioethics.
Philosophical debates have arisen over the use of technology, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and similar reactionary movements criticize the pervasiveness of technology, arguing 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.
I'm currently a class 12 student in a CBSE school. I'm interested in pursuing a career in astrophysics. I'm not sure of which university to go to for my undergraduate studies. Furthermore, my senior is advising me to apply to Indian Institute of technology. But its rank in qs top universities...
I love this, ain't it the truth! ;)

The problem statement
Hi
I'm writing a report on a design of a basic all-NAND circuit.
In reality, how are these circuits made ? Do we just use TTL etc. integrated circuits and combine them as necessary?
Thanks
Here in Missouri, MST has a very good academic reputation, but it seems this is not true everywhere. This is all wildly imaginative at this point (HS Senior), but if I were to major in physics at MST, (assuming I made good grades), is it unreasonable to hope to get into grad school at some of...
I am going to write a scifi comic and it has technology that we would see in the 22nd century. People have become spacefaring and they have built colonies on the moon and mars. Nanotechnology, robots and AI such as Cortana are commonplace. Extinct species can be cloned along with a lot of other...

I got this while I was reading spinor indices manipulating in Sredinicki's qft
in case of spinor representation we get a relation like the following one:
##[(ψ_a^{'}(0))^{\dagger},M^{\mu \nu},]= [(S^{\mu \nu}{}_R)_{a^{'}}{}^{~b^{'}}](ψ_{b {'}}(0))^{\dagger}##
where ##a^{'}## and ##b^{'}##...
The scenario is the following:
A society that is less advanced than the one producing a certain technology is exposed to the latter. The person who finds the device/fragment in question is either a A, layman, a B, trained engineer or an C, inventor/visionary, and the technology might range...
I'm a second year physics major and I want to work in quantum engineering. I think it's the future of technology. What degree should I do? I'm pretty much torn between physics and engineering physics. Obviously there's a trade off: engineering physics focuses more on applying concepts to the...

This is pretty good and seems as if the field is progressing quite fast.
This is something pretty new, why do you think that nobody take the risk to build it, up to these days? I was looking for different concepts and saw few projects from MIT, some quasiturbine projects, some liquid piston engines, doyle engine. But let's face it - too complicated, now these videos...
Does anyone feel like we're becoming too dependent on technology?
The other day I didn't have my cell phone with me and I realized I didn't know my mother's phone number :redface:; nowadays phones allow us to "touch" a name, or even say, "Call mom". It was a profound and embarrassing moment...
I just started my Mechanisms and dynamics class today for engineering. We already got the first assignment that's due in a day or so. The assignment consists of only 3 questions but first one is totally confusing me and I don't know what to do about it. I emailed the instructor 10 hours ago and...

They claim the technology degree is more hands on, and more about...
If I majored in physics would I have the qualifications to work with technology? I like physics very much and sometimes want to research but mostly I want to work with technology and find ways to make it better. Is it smart to think of a major in physics and maybe double major or minor? Or...
In a truly technologically advanced society everything is available to all for little money. If such a thing does not happen then there is no technological progress.
In 1983 the Motorola DynaTAC 8000X cell phone was 4k and as heavy as a brick. The battery only lasted a 1/2 hr. Nowadays...
Hi!
I wonder what happened to fuel-cell technology.
Is it so simple that hydrogen just couldn't be kept non-hazardous in the cars?
Or what happened?
I mean, let's face it, what more environmental-friendly can a fuel be?
The only exhaust being pure water.
And in the same time we...
