Modern computers are revolutionizing our lives, performing tasks unimaginable only decades ago. This was made possible by a long series of innovations, but theres one foundational invention that almost everything else relies upon: the transistor. Gokul J. Krishnan describes what a transistor is and how this small device enables all the amazing things computers can do. Lesson by Gokul J. Krishna

The treating of silicon with other elements to create an electron emitting N-type and an electron absorbing P-type is know as doping. It's used to create conductance. Since the outer shell of silicon is 4 valence electrons, it's easy to fill silicon's outer shell with other silicon atoms. This makes conductance hard. So, some silicon atoms are replaced.

Sometimes I feel learning science is very much important. People who choose commerce or humanities are never going to know how this world works. From quantum physics, astronomy, computer programming, engineering, hardware, chemistry, mathematics, bio technology, . everything is done in science.

And that's why in Fallout, the world still relied on vacuum tube computers, despite having nuclear technology. The transistor was never invented in the lore, so the world's computers never advanced much from the 1950s.

I get that the logical gates count 0 when there are no electrons flowing trough and 1 when there are electrons flowing trough. But what makes the transtiors switch on and off? Do we have any control on this?

Great video. It is based on very real terminology. I often find videos that are too simplistic for the topic, this is not one of them even though it might seem like it.
