@HiddenPinky @Mandlbaur @haprho You might notice from other posts that Mandlbaur completly believes AI when it agrees with him, but thinks it's slander when it tells everyone that he's wrong about, well, everything.

@Mandlbaur @haprho No. I'm sorry for you, but not sorry enough that I want to continue this conversation.

Aww, poor flerfs — they think sunsets are caused by ... perspective

@SevernDweller @Mandlbaur @packers_owner_j @Chucktown_Tiger @alexboge You'd think someone who loves skydiving (but doesn't allow himself to, because his message to the world is too important) would understand terminal velocity/air resistance.

@Mandlbaur @packers_owner_j @Chucktown_Tiger @alexboge (Actually it does reach terminal velocity very quickly due to the drag coefficient and terminal velocity. I misread the reference.) These are factors which affect ANY object moving in air, which why we can categorically say that the textbook is not modelling the experiment.

These two geniuses think I’m a flat earther and moon landing denier. On my post mocking moon landing deniers... 🙄😂

@SevernDweller @Mandlbaur @Ferrari_ball @messigoat1899 @Scotty_D_J It is an experiment, according to John, because: (this is demonstrating, again, that John will say anything in the heat of a discussion to "win", and has no conceptual permenance. Psychologically fastinating)

@Mandlbaur @AstroSpanner @Ferrari_ball @messigoat1899 @Scotty_D_J Can I compare it to lab rat's video? Amateur YouTube video??

Here's an experiment. Gather all the flerfs in the world and put them on a remote island. Just let them do their thing. How long would it take them to discover the Earth is round? 100 years? 1000 years? Never? Perhaps a small subsidiary would make the discovery & be bannished.

@vadabac340 @Mandlbaur @Danish_SMF From this (baur-research.com/Physics/CAMF.p…) you can see that JM build some marble drop corners with different radii; he wanted some of of that sweet sweet free-energy for an over-unity machine (because he believes Bessler was not a fraud). Apparently PE=KE is a difficult concept.

@Mandlbaur @Danish_SMF I will read it. What were you developing? Does it work?

Calling my understanding of science and trust in its process as 'blind faith' doesn't make your faith less blind. It just projects your method onto mine.

@SevernDweller @Mandlbaur @Ferrari_ball @messigoat1899 @Scotty_D_J OK, that fixes the "how". He won't, because of my points b and c.

@AstroSpanner @Mandlbaur @Ferrari_ball @messigoat1899 @Scotty_D_J I found this method using stationery drawer bits n bobs. The author also mentions that sextants come up on eBay. Simple conversion to celestial coordinates. So yes, anyone can measure the position. Successive position measurements to calculate speed.

@SevernDweller @Mandlbaur @Ferrari_ball @messigoat1899 @Scotty_D_J I doubt Mandlbaur could calculate a car's velocity given two photos of it taken some time apart. Doing a geocentric to heliocentric transformation is far beyond him

@SevernDweller @Mandlbaur @Ferrari_ball @messigoat1899 @Scotty_D_J You could. But Mandlbaur won't because: a) he doesn't know how b) he's lazy c) the (small) rational part of his brain knows he's wrong, and this would prove it.

@SevernDweller @Mandlbaur @Ferrari_ball @messigoat1899 @Scotty_D_J I don't think Mandlbaur (who has blocked me, because I understand angular momentum) understands what you mean when you say "reduce t" - his reply of "reduced t so fast" doesn't really make sense.

@Mandlbaur @Ferrari_ball @messigoat1899 @Scotty_D_J Didn't you say that the force on the string has no effect on the energy of the system? Also the textbook says "light string". Kevlar has the same density as polyester, so each is equally as compliant with the textbook. If you only have one data point to cling to...

@DJSnM @Dylan_Morri They can be used as teaching examples... spacemath.gsfc.nasa.gov/weekly/6Page53…

@Dylan_Morri Indeed, every engineer should be able to read specs in various units. As long as the designs they produce are consistent.

Hot take, engineers should be units agnostic

@bits2read @Mandlbaur @oscardziki @Astrophysicslad I can't reply directly to Mandlbaur (as he's bravely blocked me for the crime of telling him he is wrong) but you'll notice he is providing absolutely no evidence of his claim. Not even a screenshot, largely because a) he's wrong, and b) he's technically inept.

@Mandlbaur @oscardziki @Astrophysicslad it wasn’t wrong you’re lying again

@Scotty_D_J @Mandlbaur @messigoat1899 You can see from this thread (x.com/Mandlbaur/stat…) that others have tried to explain this to him

@Scotty_D_J @Mandlbaur @messigoat1899 It has been repeatedly demonstrated that @Mandlbaur does not understand vectors, and is unable to do simple vector calculations. He waves away valid points with cries of "moving goalposts" and insults. He is clear evidence that not everyone can understand physics.

@stringlandscape @Mandlbaur @SOPHONTSIMP John's theory works in one very specific case: a handheld ball on a string pulled in over a couple of seconds. He claims this is "the standard". It isn't It fails for increasing string length. It fails for pulling faster, or much slower. It fails for orbits. He blocks.

@Mandlbaur @SOPHONTSIMP Does your theory explain why everything that depends on standard, accepted physics works perfectly as it predicts?

Contemporary physics is predictive of pretty much everything one will encounter at energies and scales reachable via things that aren’t astronomically sized particle colliders. In general it seems false to assume we’ll keep finding new theories of fundamental physics which continue to yield new widely applicable and practical technologies forever. The road probably ends somewhere and it would not be strange for it to end at a theory of quantum gravity with few practical implications for technology beyond what exists now. With all that said, the post Umami is QRTing makes claims that do not obviously follow from a reading of contemporary physics. For instance, fusion theoretically provides particle energies sufficient to make rockets reach 0.1 C delta V’s at reasonably modest mass ratios. There is also the elephant in the room that not all propulsion methods are bound by the rocket equation, for example a reflective sail being pushed by lasers is not bound by any such limit.

Our unique view of the ISS above the horizon. This non-Earth image, taken by another satellite on March 18, captures the space station over Argentina during an active spacewalk.

@haprho @Mandlbaur Mandlbaur also believes that a good theory predicts something to better than 10% accuracy. But he doesn't know how big a satellite orbit is, and so can't work out the percentage. You are not arguing with someone who is dicussing things in good faith.

@Mandlbaur No satellite is stationary. Most satellites are predicted to better than a meter of position (attached). That's very good for objects traveling ~5km/s.

Aww, poor flerfs. Satellites are real. In the last decade, the world spent a conservative $2 trillion on them: building, launching, and running the hardware that keeps your GPS, banking, weather, and internet working. That money was not spent to trick you. Nobody wasted two trillion dollars because they were worried about what you and your ilk think. It’s over. They’re up there. Deal with it.

@AlexWeston3141 @MaytheforcebeM @Mandlbaur @SiennaSSinclair @martinmbauer I suspect this is too subtle for JM

@MaytheforcebeM @Mandlbaur @SiennaSSinclair @martinmbauer A man of limited dimension

If you use *only* data from galaxy surveys and the ΛCDM model, it predicts a cosmic microwave background with the power spectrum shown in red When you go out and measure the background radiation you get the blue data It's not circular, it's an extraordinary successful theory

@JoanieLemercier So someone's got something wrong. Either the camera doesn't have the IR filter in (as discussed in the reddit thread), it's not a class 1 laser, or the assumptions that class 1 = eye safe and eye safe = camera safe.

@AstroSpanner Class 1 lasers are supposedly safe and can not burn phone sensors.

New laser lidars are so powerful they can damage camera sensors (and your eyes). 👀

@JoanieLemercier This "source" also says it's a class 1 laser, and so safe for eyes.
