What is Technology: Definition and 497 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.

And the next step will surely be voice-synthesizing phones that can "speak" text messages to you. Or do these exist already?
have you ever pondered on just how isolated every facet of society is from one another, and our subsequent dependence on technology to stay connected and in cooperation with the rest of the world? with a population nearing 7 billion, no one really knows anyone. A very basic observation, I'm...
I feel a little giddy, so I'm going to poke a little fun at my mom. She may be stupid (still reading mom?? Keep on reading...), but she's cool in that she can laugh at herself, so here goes.

In September 1859, a -1,760nT (nano-Teslas) solar storm hit Earth. Telegraphs in the United States and Europe shorted out, igniting widespread fires.
Our technology is very young. How could we preserve it in the event of a solar tempest? Do you think it is possible to dissipate that “energetic...

I was using my iPhone when I got to thinking about how amazing it is that so much information can be transferred all with electromagnetism.
I was in a room with 500 other iphones and I could not connect at all.
is this because AT&T could not support 500 people on the same tower?

OK. Weird question.
What is a technology that couldn't exist without calculus?
Like, a specific engineered artifact -- a bridge, a segway, a waterjet cutter -- that couldn't have come into being without calculus.

Say that you want to create an index, to quantify technological level of humanity at any time.
This index puts a value on the level of today as good as the level of technological advancement year 1662 or 400 BC. It can be used in predictions of the future and so on..
