85 Big Ideas that Changed the World 524
ccnull writes "Forbes just put out its well thought-out list of 85 breakthroughs since 1917 (sneakers) that have revolutionized the way we live. This is interesting on a number of levels -- crazy trivia (the microprocessor and the answering machine invented in the same year!?), a reminder of the past (the modem: 1962), and a frightening realization that not much of interest has come out of the last 10 years (a whopping 4 of the 85 ideas). Easily digestible and worth discussing."

However we have been improving on this, and other ideas, for the last half century. Miniturization may not be a new idea or invention, but the continued process of improving an idea is just as important as the first step. Moores Law is starting to run out with computer chips, you can expect the search for quantum computing to become all the more critical when it does.
We haven't had many new ideas lately, maybe just because we are still working on the old ones?

I actually saw some Food Network show that mentioned it. It was a really big deal at the time, although I can't remember why. Probably because kids could no longer whine: "Waa! You cut him a bigger piece!"

"Thomas Midgely adds lead to gasoline to stop power-draining knocking."
As if burning fuel wasn't bad enough already add a toxic metal to it to really juice things up. It's already banned in many countries including the USA and UK.
This site [uh.edu] has further commentary and also covers his discovery of Freons that later helped damage the ozone layer including how his final invention killed him.
Surely the whole idea of such an article is to choose the inventions with the benefit of hindsight.

Sure it did! It "lead" the way for all of those "Unleaded Fuel Only" stickers that almost all of us have on our dashboards. I dunno about you, but I sure sleep better at night knowing that's there.

Without this, motor cars wouldn't have been practical. And frankly the replacements don't work as well- lead protects valve seats far, far better.

Today gas is so cheap and our standard of living so high that most people aren't terribly concerned about the amount of money they spend on gasoline.
This wasn't true in the early days of the automobile and the significant boost in mileage and the corresponding lowering of the cost of operating a car was considered important.

In addition to the rather obvious example of nuclear technology, the theory of relativity is necessary for the functionality of satellites and therefore essential to our modern communications infrastructure, GPS systems, and the many derivative technologies that depend on these systems.
Along with the discovery, development, and application of quantum mechanics, the application of Einstein's theories play an important role in the economy. I've seen studies (I really wish I had the references handy) that estimate the percentage of the US economy dependent on Quantum Mechanics and Relativity at anywhere from 30% to 75% of GDP. The higher percentages probably include indirect benefits from semiconductors, communications, as well as applications that led from derivative research.
As previously mentioned, the only reason it wouldn't have been included directly was that the list celebrates ideas since Forbes magazine began 85 years ago, not from the turn of the century when the basis for these ideas were first established.

As for the contributions of Quantum Mechanics on daily life, well, theory helps lead to invention. The idea of a "laser" becomes a lot more obvious if a theory of stimulated emission exists. The idea of using atoms to tell time becomes a lot more reasonable if you know that their behavior is quantized. It became a lot easier to develop new superconductive alloys once the BCS theory took scientists past the "guess and check" approach. Nuclear Magnetic Resonance and its well-known cousin MRI depend on quantized nuclei spins. Throw most other forms of spectroscopy in with that- the Raman effect, for instance is quantum mechanical. Scanning tunneling microscopes depend on the tunneling properties of electrons- and those couldn't have possibly have been developed without knowledge of QM. And really, QM is just starting to take center stage- in the next few years, you'll start to see quantum computing, molecular machines that take advantage (or are plagued by) quantum effects, and no doubt a bunch of stuff that hasn't been thought of yet.
