The shovel. It was a groundbreaking invention

[joetart]

Now I know how my dog feels when I'm talking to it.

[igorwojtyna]

Humans complaining that electrons are too big

I love this world

[AxelDayton]

The fact that a chunk of silicon has changed our lives in such a way is mind boggling

[flagro]

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.

[srefugee]

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.

[Mjiujtsu]

1904: 4-inch vacuum tubes invented
2016: shit we've ran out of nano-scopic space, better use quantum effects of nature

[dalegray]

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.

[arijitpalit]

Warning : without any basic knowledge of how semiconductors work, this video might be difficult to understand.

[kato_dsrdr]

When you think about how complex human machines are, you'll realize that humans in general are mad geniuses!

[SirKenchalot]

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.

[Zanzubaa]

I would also say that fire was always there, we just learned how to harness its power. The transistor is something we created. I think that is significant.

[Isopropyl_Alcohol]

1's and 0's you see in videos and pictures are made out of more 1's and 0's.

[itshalo]

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..

[ratfink]

Real Engineering: transistors are simple, let me explain.


Me: brain starts melting 15 seconds later.

[ishanidasgupta]

3:55 n-types are not negatively charged as they still contain the same number of electrons and protons. The n in the name simply refers to the valence electrons that can move inside the crystal structure

[bradscott]

I'm 55 and started in analog. I was in tech college at 17 and designed and built my first phono preamp at 16. This is the best description of transistors and electrons and holes I've seen. Great job.

[Husain_bohra]

I watched the video 3 years ago in covid lockdown when I was in 9th grade. I didn't understand it properly. Today after 3 years I watched this video again to know how transistors worked and it was so easy to understand . To all the folks who watched the video but did not understand a thing, keep hustling and it will be fine

[cowgoesmoo]

OMG
I thought that transistor was a triple-barreled artillery piece on a navy ship in the thumbnail.
