1905 is a milestone of modern physics, because it's when Special Relativity came out.
That's older than the transistor, which was commercialized in 1951. But it's also older than the vacuum tube triode, which was invented in 1906 or 1908.
In 1905, there were no amplifiers of any kind (though there were relay switches). There was almost no radio. The triode was a necessary invention for almost all of analog electronics.
Wtf is a triode?
God damn do I love it when I get to share a relevant Technology Connections video https://youtu.be/0UKCUMghTrc
three electrodes
Like a transistor only larger, less efficient and more fragile.
That's a cool story, thanks for sharing!
The wright brothers flew almost 2 years before special relativity came out.
