Internet best and most useful invention

  The Internet, a network of computers covering the entire planet, allows people to access almost any information located anywhere in the world at any time. Its effects on business, communication, economy, entertainment and even politics are profound. The Internet may not have changed the world as much as the plow, but it's probably on par with the steam engine or automobile. DARPA (Defense Advanced Research Projects Agency),...

Computer is most brain like invention

  A computer is a machine that takes information in, is able to manipulate it in some way, and outputs new information. There is no single inventor of the modern computer, although the ideas of British mathematician Alan Turing are considered eminently influential in the field of computing. Mechanical computing devices were in existence in the 1800s (there were even rare devices that could be considered computers in ancient eras),...

Lightbulb is the most useful invention

  If there's a common theme to this list, it's that no major invention came from a single stroke of genius from a single inventor. Every invention is built by incrementally improving earlier designs, and the person usually associated with an invention is the first person to make it commercially viable. Such is the case with the light bulb. We immediately think of Thomas Edison as the electric light bulb's inventor, but dozens of people...

Automobile invention

  If the steam engine mobilized industry, the automobile mobilized people. While ideas for personal vehicles had been around for years, Karl Benz's 1885 Motorwagen, powered by an internal combustion engine of his own design, is widely considered the first automobile. Henry Ford's improvements in the production process -- and effective marketing -- brought the price and the desire for owning an auto into the reach of most Americans....

Steam Engine transporting invention

  Prior to the invention of the steam engine, most products were made by hand. Water wheels and draft animals provided the only 'industrial' power available, which clearly had its limits. The Industrial Revolution, which is perhaps the greatest change over the shortest period of time in the history of civilization, was carried forward by the steam engine. The concept of using steam to power machines had been around for thousands...

Communications ways

  Maybe it's cheating to lump the telegraph, telephone, radio and television into one 'invention,' but the development of communication technology has been a continuum of increased utility and flexibility since Samuel Morse invented the electric telegraph in 1836 (building on the prior work of others, of course). The telephone simply refined the idea by allowing actual voice communications to be sent over copper wires, instead of...

Refrigeration a best invention

  Refrigerators cool things down by taking advantage of the way substances absorb and unload heat as their pressure points and phases of matter change (usually from gas to liquid and back). It's difficult to pinpoint a single inventor of the refrigerator, because the concept was widely known and gradually improved over the course of about 200 years. Some credit Oliver Evans' 1805 unproduced design of a vapor-compression unit, while...
