Which invention has been the most useful to mankind?

i think the most useful invention to mankind would be electricity. without electricy, none of our current "conveniences" would be useful. without electricity, we would have no lights, no heat, no indoor hot water, no refrigeraation for food...electricity started it all and I feel it was and is the most useful to mankind.

Manned space flight!\nThe multiple innovations that had to be overcome was tremendous and involved many different engineering fields.\nThink of all the systems that have to work exactly so that man could make it to the moon?\nHey how about the millions of parts that have to work for the space shuttle!

There are new inventions / discoveries practically every day.  The best catalog of them I've seen used to be the McGraw Hill Yearbook of Science and Technology.  But the IEEE and ACM both have great tech newsletters talking about new discoveries and inventions.\n\nIf you're tlaking about non-tech stuff, you only need look as far as the discovery of new islands just off Togo... a couple of weeks ago, a yachter discovered "pumice rafts" drifting in the ocean from an underwater volcano, and within a week an island had formed.\n\nFor a start, check out the Science News section of Yahoo.

The most important was the use of fire.  Right after that, although maybe more important in some respects, was the invention of the wheel.\n\nThe next really modern practical and convenient thing was indoor plumbing including the invention of the flush toilet.\n\nThings have come to the point where it is not so much a matter of being "better" as it is being "different".  My parents never had computers and got along just fine.  An iPod was totally unnecessary, as were peripheral things like Blueberries, and even something like cable TV was petty much unknown, and forget about cellphones, didn't exist.\n\nThe trend today is away from inventions based on steel and heavy machinery to products based on a few million lines of computer code.  The interesting thing about all of this is that as everything shifts to digital bits of magnestic dits, you will still need someone to fix your toilet.   So while the price of computer related hardware and software plummets through the floor, expect the cost to repair a toilet to skyrocket, until eventually you will be able to buy a massive supercomputer the size of a slice of bread for $20 but the cost to fix your toilet or unclog a drain will shoot up to well over a hundred times that.\n\nThe reason is simple: for every 1000 computer engineers, programmers and technicians, there will be only 1 plumber.  So in the future the programmers and computer technicians will be working 80 hour weeks for a barely minimum wage and living in public assisted housing projects whereas the plumber will be working a 20 hours week and living in a mansion, driving a Mercedes and a Bentley, and taking vacations to the Islands every month.

I'm a freshman in college, and I'm really not used to studying (never had to before.) A nice invention would be something that could copy things from a book and paste it into your memory -- short or long term. That would be a big help.

Noone invented it. It is a natural phenomenon which humans have harnessed, channeled and learned to store.

The traffic light\nGas masks (both by Garrett Morgan)\n\nLong haul refrigeration systems on trucks.\n\nThe ironing board.\n\nOpen heart surgery.\n\nStreet sweeper trucks.\n\nThe electronic resistor (for which help make electronics possible)\n\nThe filament in a lightbulb (for which was Edison's toughest feat)\n\nThe WC (restroom) on trains.\n\nModern music.\n\nThe super soaker.\n\nThe jenny coupler (it links railroad cars, a dangerous task for which is how it's black inventor Andrew Beard, lost his leg.)\n\nCarver invented peanut butter, adhesives, bleach, chili sauce, ink, instant coffee, linoleum, mayonnaise, paper, plastic, pavement, shaving cream, talcum powder and more.\n\nMatzeliger invented an automatic method for lasting shoes, which made the mass production of affordable shoes possible.\n\n\nDr. Charles Richard Drew invented the possibility of blood banks.\n\n--------------------------------------------------------------\n\nSo enjoy your affordable shoes, PB, music, anything electronic that you have, milk when you don't live near a dairy farm, your flat shirts, clean streets, incandescent lights, vacuum tubes... but don't say black people haven't done anything to make life more livable for you.

His name was Alessandro Volta.  Alessandro Volta discovered the first practical method of generating electricity.  In 1800, he arranged zinc and copper discs in a column and invented the battery.  His most famous invention was the voltic pile. \n\nThese links should give you all the good stuff!

An invention: Cellborg ( http://www.livescience.com/technology/051027_cellborg_sensor.html ) massive potential to become useful in our lifetimes\n\nA discovery: new blackhole ( http://www.space.com/scienceastronomy/050509_blackhole_birth.html ) very little potential to become useful in our lifetimes, but oh so cool\n\nOffbeat: monkeys have accents ( http://news.yahoo.com/s/afp/20051129/od_afp/japananimalsoffbeat ) it has to do with monkeys and I personally find study language fascinating

Well just look around you. Every breakthrough is made by the help of physics. Electricity, gravity, magnatic fields, planes motion rockets launching, water movement and almost everything. \n\nIf you're asking for general knowledge i think you will never stop finding out how physics is helpful. If you're asking just to write an essay for school, i think you can google it and you'll find million results. Good luck.

I bet you can sit in your CHAIR in front of the COMPUTER, drinking a SOFT DRINK in a PLASTIC TUMBLER, listening to a RADIO and snacking on POPCORN popped in the MICROWAVE.\n\nThink about it... all you have to do is look around.  \n\nIf you are not living in a hide tent, hand starting a fire and cooking a rabbit you killed with a sling over a wooden spit, then you can see the evidence around you on how Science has benefited human beings.

The plough.  \n\nNo plough means no agriculture, no surplus food, no urban life, no artisans, no geometry, no language, no government, no sciences.\n\nNo *nothing* without the plough.  We'd still be gatherer/hunter nomads in Africa saying "Ugh!" and worshipping rocks.\n\nThe second greatest invention was Gutenberg's printing press.

The most important device is the dynamo\nIt was invented by Michael Faraday, hardly 2 centuries ago\nThe 'watermill' was invented already more than a millenium ago.
