Penicillin, before the discovery of this, the original antibiotic, thousands of people were dying from common bacterial infections every year, if the pre-penicillin death rate were to be converted into today's population, the death rate would easily be in the millions.

Hands down it has to be the computer. It's completely changed our lives. It's changed how we live, how we communicate, how we do business... it's cause the greatest change in the the 20th century. I think that the discovery of the human genome (the DNA strand) comes in a close second, and I anticipate that in the 21st century discoveries related to the human genome will have the greatest impact.

Einstein's theories of relativity and special relativity, hands down. They were unprecedented in depth and scope, leading to numerous discoveries and developments in other fields. They broadened our understanding of the physical world and universe.
A partial list of things that relativity gave us include:
1. the Atomic bomb
2. Nuclear energy
3. Chemotherapy and other cancer treatments
4. X-rays, Pet scans, SPECT, Cardiovascular imaging and Bone scans
5. Stem cell technology
6. Cloning
7. Micro-biology
8. In-vitro fertilization
9. DNA evidence
10. the Big-Bang theory
11. Measuring the shape and size of the universe
12. Space travel, rockets, the space shuttle
13. Black holes, pulsars, white matter and anti-matter
14. Theories on time travel and tele-portation
15. gravitational waves
16. Quantum theory
17. Neo-Natal surgery
18. Doppler radar
19. Satellites
20. Bionics
I could go on, but I won't. These are just a small sampling of what we have been able to derive from relativity. Whether or not you agree with everything science and technology are doing, you have to admit, it is a very impressive list.

I have to agree with LeftField, The cure for Polio has enabled children to be children, instead of cripples.
I agree that the T.V. and the personal computer has changed the way we see the world, but what good would it be to a person who is bed-ridden or locked in a wheel chair because of a preventable disease?

In my opinion it would be Jonas Salk's polio vaccine ..it is hard to tell how many children, the world over, have been saved from this disease because of his vaccine.....

Definitely the television. It has changed the world more than anything else ever has or will again.

That the universe is a black hole generator, and that life is it's incidental.
Don't feel small, feel lucky.
