This video showed me how transistors are made, I didn’t know it was so simple, thought it was a lot more. Of course, these are the basic concepts but I mean in regard to those. I knew about NPN, PNP or PN junctions for a long time, but didn’t know they could be made through such simple doping techniques.

Perfect explanation of the visible colors and what’s causing them in our brain.

:stuck_out_tongue: overlapping teal and yellow does not make green using light, but blue and yellow pigment does make green. I’ve not seen or understood what mixing two sets of mixes together make such as yellow or magenta mixed together which were mixes from two other colors, but it stands to reason more towards white.
