For context: life expectancy (from birth) in the U.S. went from 50 years in the first photo to 70 years in the second photo. Another giant leap for mankind.
Since then, the value has increased further by almost 10 years.

Wilbur and Orville's first flights were 112 and 120 feet respectively, shorter than the wingspan of a 747. The 4th (and last) flight of the Flyer was 852 feet.

@wonderofscience This is a wrong comparison to make IMO.
You should compare with photos from early rocket enthusiasts.

Call me pleasantly surprised if we do.

That is not just our science, but our capacity to creat, assemble and build.
The above is just as true for our society, _poverty is now fake, a _construct, built _around people. It _costs EXTRA to maintain poverty.

"The universe is probably littered with the one-planet graves of cultures which made the sensible economic decision that there's no good reason to go into space -- each discovered, studied, and remembered by the ones who made the irrational decision."

@wonderofscience It’s really astonishing how small the window of time is in which every modern mode of transportation, from the bicycle to the supersonic jet, was invented.

@monkeyborg @wonderofscience
Just to be annoying, I'd like to point the tautology in saying "modern" (c. 1500 - 1950) and "small window of time".
Though of course you are right: the slow abandonment of Aristotelian worldview necessitated additional introspection and research, which in turn led to new problems becoming pressing enough to demand solving.
(From European POV, ofc)

Big part of rocket development was the experiences with the Paris gun. After that, Germans knew that the bullet had to have a propulsion system of its own.

@wonderofscience To be fair, the top image should be Robert Goddard with his similarly early liquid rocket, which would have dated to 1926. So, 53 years from the earliest liquid fueled rockets.

Ummm, you mathed wrong - it was 53 years apart and we are now that far along from the second now as the first was from the second.
All we have to show for it is the iPhone. Our early promise has rewarded us with good stuff - no doubt, but the scope of human progress since the moon landing is a tepid cup of tea at best by comparison.

It's been 55 years since the bottom picture, and air/space travel have not significantly improved since then.
Planes are a little safer and a little more fuel efficient. Low Earth orbit is more cluttered. Other than that, not a big change.
=> More informations about this toot | More toots from tofugolem@mastodon.social
@tofugolem @wonderofscience
Getting the plane to fly more than few metres to having it fly intercontinential was a work of 20+ years (1927), and getting from that to passanger flights took another ten years (1938).
Then followed pressurised cabins which allowed quadrupling the flight height from 3 km to 12 km; faster speeds with Concord et al, bigger payloads etc.
In a way, the flight industry's pivot to solar and electric motors is a return to the problems of Wrights: miniaturisation!
=> More informations about this toot | More toots from iju@mastodon.social
@wonderofscience
I'm using this to point out that Wrights didn't just pop out from the sea, but that they stood on the shoulders of others.
The missing piece was their skill as bicycle manufacturers to bring the weight of the components down.
There are stories of unthethered flight before Caley, but as the saying goes: inventor is the one who invents something last (eg. writes their method down and demonstrates use worth copying the method), not the one doing something first.

@wonderofscience Wow, what an incredible testament to human ingenuity and progress! It's mind-blowing to think that in just 66 years, we went from taking to the skies for the first time to setting foot on the moon. This truly shows the power of innovation, determination, and dreaming big. Imagine what the next 66 years could bring!" 🌍✈️🚀🌙

@wonderofscience This reminds of something that's been on my mind lately.
During this period of rapid development of aerospace tech we believed that we'd have colonies on Mars in years. Yer shortly after the progress seemingly stalled. Problems have become more difficult.
In the recent decades we've seen similar progress, but with information tech. And it is obvious that the growth we've seen is over. All the easy problems have been solved. And the recent crypto and AI bubbles are just copium.
