  1. Field Effect Transistors work completely differently than bipolar transistors do. It is a totally different topology too.

  2. Máté Varga almost only counts with horseshoes, and hand grenades. Binary Junction Transistors (BJT) are current controlled devices. Field Effect Transistors (FET) are voltage controlled. A BJT has a Base, a Collector, and an Emitter. A FET has a Gate, a Source, and a Drain. They're completely different.

  3. FINFETs are MOSFETS. They are just a different geometry. The "FIN" in FINFET refers to the shape. The shape appears to have fins. But the materials used in construction are exactly the same. So they are still Metal Oxide Semiconductors, Or MOS-FETs. Only the exact set of processes differs to produce a new style component.

  4. Nick John but internal combustion does not need to be efficient. We just pump fuel out of the ground for it. Which is solar in nature. It was the Sun's energy that made all of that life live when it did. So oil is solar! It is just stored solar energy.

  5. Component part density and network speed are vastly different things. We have reached the limit with the common method of manufacturing integrated circuits now too. At this point all of the low hanging fruit has been picked. The top of the tree is stripped bare too. There is no more tree in fact. The tree in question is the usable part of the electromagnetic spectrum that we can use in the process of chip manufacturing. Which stops at 22 nanometers. That is why 24, and 32 nm parts are so common today. They're the end of the trail. Past that you have to get into exotic techniques to manufacture things. Read incredibly difficult, and expensive.

  6. We use decimal because we have 10 digits (fingers). Computers only have on, and off. So there are only 10 types of people in the world. People that understand binary, and people that don't.

  7. Morten Kristiansen yeah and as an added bonus FETs explode!

  8. If you think we didn't need gun tables after the war ended you've got another thing coming.

  9.  @jupiter8512  later on it did in perfecting them. The first point contact design was scrapped. Was more of a wow it works type of thing. But it working got Shockley to thinking. He was a genius when it came to atoms, particle physics, whatever it is. So he designed the planer transistor. Which was actually a viable commercial product.

  10.  ungratefulmetalpansy  our species ate without agriculture for a lot longer than we've eaten with agriculture. Agriculture had some other negative effects on our species too. It's the reason we have wars now for instance. Before the advent of agriculture there wasn't so much property ownership. One piece of undeveloped land was pretty much the same as the next. None of it seemed worth fighting over either. Every silver lining has a cloud around it.

  11. Which Industrial Revolution? There were at least three of them. You might mean the Age of Enlightenment, which lead to the First Industrial Revolution. If you were to examine the First Revolution I doubt you'd think much of it. But it was important nevertheless.

  12. A solar panel is a silicon wafer that is too defective to make integrated circuits out of. Often. Though with increased demand and better wafer yields the industry has had to make wafers just to make panels out of.

  13. Nick John Yeah there's that crappy amorphous stuff too. The best panels are bad wafers.

  14. Nick John what solar panel is 87% efficient?

  15. jaw jacking ain't making me a sammich.

  16. IamGrimalkin are you sure? Do you speak fluent bee?

  17. Computers now compute many bits at a time. Today 64 bits is commonplace.

  18. manictiger sure, and they don't make those ICs with the photolithographic process either. Intel uses CNC lasers to cut the dies. Which is totally insane.

  19. Máté Varga bipolar is binary. It means two.

  20. Máté Varga it could be. You just did in fact.

  21. Máté Varga if you're trying to make fire you're far better off with a FET, than an old BJT. Because FET stands for Fire Emitting Transistor!

  22. Tell me of a private business that has gone further than NASA has. I'll wait. Results are all that matter.

  23. MrSirFluffy  we were never interested in space exploration in the first place. We only did it to prove that our way of life was better than communism. They did it to try to prove they were better than us. Well, they did it because they knew they couldn't compete with us when it came to strategic bombers. So they decided to change the game, and pursue something that we weren't doing. But once the cat was out of the bag, we quickly caught up, and surpassed them in every way. NASA still holds virtually every record there is in spaceflight too. They haven't really made a serious effort since Apollo either.

  24. MrSirFluffy NASA just doesn't service the ISS. NASA still performs all of their other mission launches though. Really, our government has no business exploring space in the first place. Nowhere in our Constitution is there any requirement of our government to be involved with space any more than it concerns our national defense.

  25. 4 bit binary is hex. That was covered in this video too.

  26. Well there's the high impedance Z state. Which is kind of like I have a headache right now...

  27. Colossus was not a programmable general purpose computer. It was a purpose built pile of junk! Made out of surplus bits of rubbish they could scavenge from the post.

  28. ***** I can appreciate different perspectives in matters. Get it?

  29. ***** not surprising

  30. ***** it is philosophy, and the comment section of YouTube is hardly the place to expound on that topic. Suffice to say everything in the Universe has a perspective. You, me, a tree. Being able to see things from a perspective besides your own can be valuable at times too. It can offer insights not naturally available.

  32. Input. The better question is where does input come from? The answer to that is a number of places.

  33. The ENIAC was the first general purpose computer made. The Colossus was a special purpose machine. All it did was crack code. You couldn't program it to do anything else.

  34.  @Mezmorizorz  I went on your channel to see the better video you'd made but you haven't uploaded it yet. What's taking you so long?

  35.  @arjunarunkumar3097  we thought we were hot atomic shit until we discovered a natural nuclear reactor. Somewhere in nature there may be natural transistors too?

  36. We knew plenty before writing was developed. I slap you upside the head and you'll know things!

  37. That's because you prefer colored distortion. Transistors are orders of magnitude more accurate than tubes are.

  38. @Dicky Mcgeezacks we had to invent a way of generating electricity. Just like we had to invent ways of starting fires. BTW Quest for Fire is an awesome movie.
