What do YOU think is the greatest invention in the past 50 years?

Pi, Quantum mechanics, the calcatronic 1950s computer, cloning, medical improvement. These are all things we couldn't go without. Without a calcatronic computer there wouldnt be a modern computer. Without quanutum mechanics. There would not be a calcatronic computer, without pi. There would be no Titanic or civil engineering, without cloning, there would be no medical improvement, without medical improvement, people would still be dying from simple things like a cold or a bruise!

i would say the AC/DC motor. Invented far ahead of it's time and still being used today.  From air conditioners to alternators, even electricity from Hydroelectric dams. The best invention that's keeps on giving for free.  Generators that if you turn create electricity or if Fed electricity it would turn.  Works one way and same thing the other way around.  Also the wheel it was a beautiful invention and still is in use today.

Nano technology is the latest buzz which have tremendous scope in coming future because we are going towards slimmer gadgets with greater features and nano technology is the only solution which can make this happen.\n\nGood luck

I think the scientists who made the greatest contribution of all time was Alexander Gram Bell even though he was not really scientists and more like a inventor. His invention the telephone is what now makes the world go round. The telephone lead to the internet, and being able to send mass amounts of information.

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.

There's a little more to it than that. These sites will help you to find what you're looking for.\n\nhttp://www.disclosureproject.org/Outsidethebox-TedLoderPaper.htm\n\nhttp://www.disclosureproject.org/writings.htm\n\nYou can follow links in these pages to see the actual models built from patents aquired in the 1950's.\nYou could build one too.

Realistically? The search for knowledge has led to, or had a significant contribution to, the development of microwaves, radar, radio, superconductivity, computers, refridgeration, digital cameras, the internet and much more. When the theories that underpin most of these inventions were first discovered and tested, many people asked the same question - how does this help me? And then 20 years later some clever engineer invents a little box that heats up food. So give it time - almost every invention know to man once started as someone saying "I wonder how this works?"

talk about our new world order\nand what is the changed that happened to our life the last 50 years till now

This 21st Century is really something, isn't it? Truly amazing.

I would say computer technology.

A time machine.\n\nI have always been fascinated with the concept of time travel, changing the past and seeing the future.  \n\nActually, I think most people are. \n\nMost have thought "What if" I could go back in time and rearrange a key event in their past or in history. \n\nThe future, of course, would just be fun to gaze on.  So many things have changed in the last 100 years, it's difficult to imagine where we might be in another 1000 years...if we don't destroy ourselves.\n\n...but even that would be fascinating to see:\n\n"The day the earth died".

umm...no, fiberoptics is not the answer. duh. Fiberoptics is good and fast, but it has serious cabling problems. 2020 is hard to predict but most likely things will be wireless, cellphones smaller and integrated with other stuff like  camera/phone/mp3 player/pda....sort of like we have now\ntv, well hdtv is about the limit on that, unless they make cable wireless....which I highly doubt. But recording shows and stuff will ofcourse be more popular. Most likely the tv will be combined with the computer or vice versa. But along with all this will come problems and people will complain, but won't realize that they are alot better then when it was in 2005.  There will either be multiple computer brands instead of just microsoft, apple, and linux, google will probably have an operating system. Intel will probably start going down the tube while AMD keeps getting better...like always. Perhaps more eco friendly cars, or other products. But truthfully, technology doesn't move along that quickly. Things will probably get more smaller or even become integrated into our bodys, things will be easier and better....but nothing will come as a big leap. After the invention of the semi conductor technology has only been taking very small baby steps, the closest big step is nanotechnology, and even that has it's problems. but ofcourse, Who knows? :)

the time should be about 50 years!

Hardware, it's happening now. The people who invent a new way to store data, better batteries and can combine devices into a single unit. \n\nThe first person to triple the best batteries we have now and make it twice as small will be the next billionaire. Investing in hardware companies is the brightest solution.

Alexander Graham Bell.\nHe introduced us to advanced communications. telecommunication, communication in general (via phone, computer, or video) is probably the biggest and most influential invention of all time.  It dictates our whole world in every aspect of our lives.   Where would we be without cell phones or email and all that encompasses those!

Approve stem cell research. This will be the next great technology. If we conceed this to off-shore interests, the game is over.

Fire\n\nInvention? Or discovery? *shrugs* But I'm thinking most of all we need and use just wouldn't be around without this heating component. Just a thought.
