Comments by "yxyk" (@yxyk-fr) on "Asianometry" channel.

  1. and it's only a superficial overview 😀

  2. what is the difference ? They made a device and observed unexpected behavior : this is a discovery.

  3.  @mr2981  patent offices have a different meaning for the word "inventor".

  4. it was mentioned quickly... but a detailed documentary would run for 4 hours at least !

  5.  @piotrkozniewski  During the early days, Czochralski's method was barely starting. "zone melting" was more common, at least in the very beginning, for experiments and small productions. as volumes increased, zone melting was not reliable and scaleable enough.

  6. hopefully a future video. Then a video about Bose, who first witnessed microwaves.

  7. why is it irrelevant ? Did Lilienfeld make reliable FETs ? And how did Czochralski invent transistors ? crystal-making is only one part of the fabrication process, a transistor is much more than that...

  8. "Computers are made of field-effect transistors." The CDC6600 (1964) contained approximately 400,000 transistors (cf Wikipedia, other figures range from 300K to 600K). Today's equivalent part is the 2N2369, an epitaxial bipolar gold-doped NPN. So Shockley's theories are totally relevant to computer history. MOS processors appeared a decade later when they became cheap enough but you could find bipolar processors well into the 80s. The Intel Pentium used BiCMOS : fast parts in bipolar and slow/low power in CMOS (caches for example).

  9.  @polka23dot70  we're not even counting Bell Labs geniuses like Claude Shannon, Niquist and (i forgot who) who made the first remote-accessed relay calculator right before/during WW2.

  10.  @cogoid  so yes, as i understood earlier, this "choice" was a combination of factors. Thanks for confirming 🙂

  11. what is it ?

  12.  @Schlipperschlopper  I have no online reference about the use of duodiodes, I have only found that they were invented in hope of cancelling noise in the radar rectifiers. "interference" was observed but from the little I had found, no amplifying device was built. Mataré and friends were hired in France to build a diode manufacture and brought the idea with them and could at last make a working device, which was quickly (and shortly) adopted by the French State. But point-contact devices have many shortcomings that later alloyed types would overcome and it was too late for the French. Some people have traced / located early Transistrons in museums and private collections, but never heard of any predating device. Please can you provide more information ?

  13. I'd read it.

  14. you seem to have opinions. Great. it's good to reflect on what happened. But don't let your ignorance and a book make you reinvent History to your liking. History doesn't care what you think. Oh and you're totally off-topic here.

  15. Indeed,  @cjay2  Schottky nailed the theory a decade before the transistors were discovered. It took a while to purify silicon and germanium enough to transition from point-contact to molten/doped methods. People at Bell Labs played with "zone melting" and found that they could control the doping by changing the speed of motion. Hence create bulk diodes. It took little effort to convert the process from PN to PNP, using Shockley's theories.

  16. 13:09 "the presence of vacuum" is the absence of air, right ? 🙂

  17.  @marianl8718  Just a few hours ago I saw on FB a circuit that uses a LED as rectifier for AM reception 😀

  18. and the standard transistor symbol directly derives from it. mind blown, heh ?

  19. Hmmmm excellent question ! Keep us informed of your finds !

  20. 10:00 gain of 100 ? that looks large, I heard gains of maybe 20 or so ...

  21. do they like you in return ? 🙂

  22. That sounds like a job for... Wikipediaaaaa ! 😀

  23. sure, the author is Asian... anything factual to argument ?
    1
  24. nope, just a long work and industrial evolution... each step enabling the following one.

  25. yet it happened... This greatly confused the Soviets because the Soviets believed the US would try to mislead them toward a technological dead end. Meanwhile the Western bloc ramped up production and technology like crazy and left the Soviets lagging a decade behind. (summarized from a Russian page I found last year while researching the subject from different angles)

  26. Except that Mataré observed it during WW2 but couldn't study it.

  27. 9:47 shots fired... but fair enough.

  28. maybe this video was not about eugenics.

  29. it's a charged question ;-) and what if salmons un-ionize ?

  30. Thanks for the free advertising ! I indeed opened my own fab last month, and "Redacted" is an awesome brand name !

  31. 7:41 Stanf*u*rd ? 😀

  32. ... or you're going bananas ? 🙂

  33. Wrong. Nobody can be supercomputer'd out. Do that Japanese SC video at last !

  34. something like "never"

  35. it's an endless rabbit hole so the real merit is going back to real life and report about the trip 😀

  36. yup  @MrGGPRI  that was a typo 🙂sorry

  37. not discovered : invented/conceptualised, hence why BBS were seeking to implement it, but they lacked proper crystal purity. what they discovered was a different effect.

  38. we all know what patents are worth @1pcfred  ...
    1
  39. And the contact transistor was "invented" in at least 2 unrelated places.
    1
  40.  @cogoid  Daaaamn.... that may have explained why they had so many problems making something work. They were used to vacuum tubes and their surroundings. Soon after the voltages were reduced to 21 or 9V, when the breakdown voltage effect is understood.
    1
  41. on the contrary hahaha ;-) literally ;-)

  42. too late, he got nobelized...

  43.  @Viertelfranzose  and you have reliable and useful links to provide. information that would rewrite history and earn Nobel Prizes.

  44.  @jimsimpson1006  you mean space heaters ? 🙂

  45. I have a microchannel system ! It's a Tektronix 2467, 4×350MHz analog 'scope, a delight to use but there is the warning to not push the sensitivity/light too high / too long or it could get damaged...

  46. ah, the UNIX epoch is something different 😛 it's zero hour for /computers/
    1
  47. is that good or bad ? 😛

  48. More cold open jokes please.

  49. yeah you gotta replace all those maimed productive guys :-/

  50. Meanwhile politically-motivated right-wingers attribute the relative delay to the-strawman-of-the-day (The Hill accuses DEI...)
