How many scientific journal articles from the late 1800s to the early 1900s have you ever read?
Have you ever studied about how Millikan measured the charge on the electron?
Have you ever read Einstein’s paper about how Brownian motion is used to estimate the size of molecules?
All that work and other efforts formed the basis for our modern quantum mechanical knowledge. They used very crude methods with much mathematical pencil and paper work to make amazing discoveries.
Admirable? Of course!
Alien? I think not.
There is human hard work and intelligence used to build and discover all of our science.
