    I know this is damning to admit here, but back when I was willing to watch Joe Rogan I distinctly remember during Elon’s episode (the one where he hit a joint and tanked Tesla stock, not the latest one), the topic went to electric airplanes. Elon was talking technical about it and Joe was sitting there wide-eyed like he was revealing the secrets of the weave of the universe, sure that aerospace was going to be revolutionized by this man.

    Maybe I’m the stupid one here, but I’m pretty sure he was just talking about how airfoils generate lift. You know, the stuff the Wright brothers figured out in the 19-aughts. Its in high school physics textbooks.

      Angela Collier just released a video about how billionaires really want to be seen as physicists, whilst most of them dropped out of college. “I could’ve become”, “I considered to” and so on.

      They really want to be perceived as smart. I don’t get any brownie points for saying “I thought about getting a PhD”, why should they?
      Especially when they can hire several professors to teach them personally with their billions of dollars.

      It’s a long video, but well worth the watch.

      Most technology is magic to the average person. It doesn’t take much to sound like an expert.

        For a number of years now, work has been proceeding in order to bring perfection to the crudely conceived idea of a transmission that would not only supply inverse reactive current for use in unilateral phase detractors, but would also be capable of automatically synchronizing cardinal grammeters. Such an instrument is the turbo encabulator.

        Now basically the only new principle involved is that instead of power being generated by the relative motion of conductors and fluxes, it is produced by the modial interaction of magneto-reluctance and capacitive diractance.

        The original machine had a base plate of pre-famulated amulite surmounted by a malleable logarithmic casing in such a way that the two spurving bearings were in a direct line with the panametric fan. The latter consisted simply of six hydrocoptic marzlevanes, so fitted to the ambifacient lunar waneshaft that side fumbling was effectively prevented.

        The main winding was of the normal lotus-o-delta type placed in panendermic semi-boloid slots of the stator, every seventh conductor being connected by a non-reversible tremie pipe to the differential girdle spring on the “up” end of the grammeters.

        The turbo-encabulator has now reached a high level of development, and it’s being successfully used in the operation of novertrunnions. Moreover, whenever a forescent skor motion is required, it may also be employed in conjunction with a drawn reciprocation dingle arm, to reduce sinusoidal repleneration.

          The missile knows where it is at all times. It knows this because it knows where it isn’t. By subtracting where it is from where it isn’t, or where it isn’t from where it is (whichever is greater), it obtains a difference, or deviation.

          The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn’t, and arriving at a position where it wasn’t, it now is.

          Consequently, the position where it is, is now the position that it wasn’t, and it follows that the position that it was, is now the position that it isn’t. In the event that the position that it is in is not the position that it wasn’t, the system has acquired a variation, the variation being the difference between where the missile is, and where it wasn’t.

          If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the missile must also know where it was.

          The missile guidance computer scenario works as follows. Because a variation has modified some of the information the missile has obtained, it is not sure just where it is. However, it is sure where it isn’t, within reason, and it knows where it was. It now subtracts where it should be from where it wasn’t, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn’t be, and where it was, it is able to obtain the deviation and its variation, which is called error.

        I have literally baffled people with my knowledge of Neolithic technology, the fact people stuggle with modern technology isnt exactly surprising.

        Not everyone, only the rich ones.

        I remember Neil deGrasse Tyson, and it was a completely different attitude than anyone rich, no matter how technical or dumb they are.

        Joe is a motherfucking asshole, nobody should listen to anything he says, or anyone else willing to go talk to him.

      I understood lift pitch roll yaw etc in grade school when I became obsessed with making paper airplanes.

      I speak house now?
