Some older but useful kinds of information :
About space CPUs and about making CPUs resilient against radiation AKA radiation hardening :

And a museum site with all kinds of books in pdf format like for example the famous Radioshack / Tandy "Engineer's Mini-Notebook" from Forest M. Mims III.

This is a bit more old school, and information is probably a bit dated in some regards as new discoveries have been made, but I remember I really liked the book "Powers of Ten" as a kid. Lots of cool science stuff in there from galaxy clusters down to quarks. There was also a short movie made of it.

Around 8:08 it is mentioned that every atom has protons and neutrons. Strange that they forgot the hydrogen atom which consist of a proton and an electron when electrically neutral. Deuterium is hydrogen with a neutron, a bit more than wice as heavy. Or is hydrogen special ? It already has special capabilities.

Yeah most Hydrogen atoms have no neutrons. Though deuterium and tritium do, these are far less common.

I looked it up, cause i thought Deuterium was rare and Tritium even more. In fact, it is not... Relatively speaking.

According to this site :
"
Deuterium is common: about 1 out of every 6,500 hydrogen atoms in seawater is in the form of deuterium. This means our oceans contain many tons of this hydrogen isotope.
"
Just need a special kind of centrifuge to separate the hydrogen isotopes based on the mass(weight).

This video tells me that our energy production methods are REALLY primitive:


The efficiency ratio for this physical phenomenon (input vs. output energy) seems to be insane.

A site about old stuff , but very interesting, educational and a good place to learn from : Mr Carlson's lab


A nice video about a wire recorder from the 1940s, that electric field probe is also very interesting :
