...The era of the early and mid 1900's is also marked by extraordinary revolution from the telephone, automobile, airplane, radio, radar, computer, manufacturing, and medicine, which have only been refined and improved on today without fundamental revolution.
The list of achievements from the recent generations are comparably poor with some achievements in certain areas, but have not provided a comparative revolution to society to dignify the generation on. These later generations have only managed to continue or arguably degrade the status quo.
The digital revolution is all since 1950. The first transistor was in 1947 but the first chip was 1958, Moore coined what we now call, his famous 2nd law in 1965. The cell phone in your pocket has far more computing power than a room of equipment even from the 70s. The internet grew out from the ARPAnet in the 70s. We have the manufacturing revolution from 3D printing. Automated low cost genetic sequencing is revolutionizing medicine. Crop yields that remained stable from 1880-1950 have risen consistently since thus letting us (mostly) feed the world. Of course there is space flight and its resulting vast increase in knowledge of the universe and our own planet as well as numerous commercial applications in farming, communications, mapping, news gathering, etc (but Tom thinks those are all false of course). Likely more important than anything is the focus on sustainability. The practice of burning fossil fuels without regard for the consequences to our environment that was so eagerly embraced in the first half of the 1900s which set the precedent for the 2nd half, has lead our civilization to the very brink of destruction. If we manage to step back from the edge, which is not yet clear, it will be the greatest accomplishment in history.
None of that later technology is as revolutionary as the technologies from the beginning to mid 1900's. Most of what you cite originate from the time period I cited or even earlier.
So when did digital electronics start?
The 1950's already had radio communication and cell phones were just the natural progression of that technology rather than something truly revolutionary.
This just show how little you know. Celllphones are a fundamental departure from analog radio.
The 1950's had plastic molding.
If that is supposed to relate to 3D printing its nonsense as the entire point of 3D printing (in plastics or metals) is that there is no mold.
1940 Germany even allegedly had rockets capable of getting to space. Sputnik happened in the 1950's.
So does space flight exist or not Tom?
The 1950's had computers. The internet and personal computing are one of the few new things that are revolutionary to society, but the 1950's had the analog equivalent of digital libraries, photoshop, microsoft office, online shops, and bulletin boards.
Are you talking about actual brick and mortar libraries? Hardly the same thing as a library in your pocket via your cell phone.
Genetic engineering is still in progress.
Of course but NOW not in 1900 and it has already revolutionized virus detection and vaccine construction.
The Moon Landing was supposed to be a test case for colonies on other worlds, but never came. The best theory about gravity in science comes from 1905.
Special Relativity published in 1905 as
On the Electrodynamics of Moving Bodies is not about gravity but about how space and time are merged. General Relativity IS about gravity and was first published in 1915 (at which point the 1905 paper became commonly known as Special Relativity) and confirmed in several ways since (time dilation via atomic clocks at varying altitudes and gravity probe B). Plus the significance of space flight is in the huge amount of knowledge we have and continue to gain on the cosmos and our planet, not the moon landing. But are you now claiming the moon landing was real? Haven't you claimed it was all faked elsewhere on this site? If the moon landing (and space flight in general) is real then the earth must be round, the two can not be separated.
