The shovel. It was a groundbreaking invention
-
Humans complaining that electrons are too big I love this world
-
The fact that a chunk of silicon has changed our lives in such a way is mind boggling
-
The transistor described here is the junction transistor. But the device used in most digital ICs is the field-effect transistor, which operates more like a vacuum tube.
-
Now I know how my dog feels when I'm talking to it.
-
1904: 4-inch vacuum tubes invented 2016: shit we've ran out of nano-scopic space, better use quantum effects of nature
-
When you think about how complex human machines are, you'll realize that humans in general are mad geniuses!
-
I had a physics class taught by Dr. Brattain at Whitman College in the 1970s. I was having trouble with calculus and he took the time to show me and made it seem so simple that I was able grasp it. . I have always been grateful to him for that.
-
I didn’t know anything about transistors before watching this video and somehow I know even less.
-
Warning : without any basic knowledge of how semiconductors work, this video might be difficult to understand.
-
The line about running into the issue of quantum tunneling when trying to make transistors smaller blew my mind and really put into perspective how truly small they are. Like quantum physics, a form of physics that is so unlike classical physics, the thing people watch videos on and will most likely never even think to actually encounter, is becoming a hard barrier for computer chips, something we use every day… woah..
-
The fact that something made from sand runs the whole modern world is simply marvelous
-
Real engineering, I don't know if you're going to read this but PLEASE keep making videos. You are one of the few channels that actually explains things without simplifying it to the point that it's incorrect.

my brain hurts i need more ram
-
THANK YOU SO MUCH, you've successfully answered all my questions that were bothering me for my whole life in 8 minutes!!!!!
-
This is such a good video. You've no idea how many "what are semiconfuctors/transistors" videos I've watched and not quite gotten it, but this was the one that got me to understand.
-
Real Engineering: transistors are simple, let me explain. Me: brain starts melting 15 seconds later.
-
I fell like you skipped how you turn transistors into logic gates which was a kinda key part of the simple-to-complex story you told. Thanks for the video though.

Great video! Additionally, thermal challenges caused by the decreasing size, increasing density, power consumption and inadequate cooling techniques (mainly convection with air, and watercooling more recently) are also causing the decline in performance improvements with each iteration. Splitting the cpu’s into different cores managed to increase computing power further, but the performance on a single core basis hasn’t really improved that much since around 05/06 :)

fire wasn't a invention, it was a discovery
