@Ferrari_ball @SevernDweller @Mandlbaur @Chucktown_Tiger @alexboge If I remember correctly, JM has contacted Dr Young and tried to get him to agree that he thinks there is no torque in his demo.

History has not recorded the exact comments, and JM is very quiet about what he actually said. But I'm sure he didn't agree...

[Will Grainger 🐀 @AstroSpanner]

@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.

[Will Grainger 🐀 @AstroSpanner]

@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.

[Will Grainger 🐀 @AstroSpanner]

@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)

[Will Grainger 🐀 @AstroSpanner]

@vadabac340 @Mandlbaur @Danish_SMF From this (https://t.co/DYPDu95jJo) 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.

[Will Grainger 🐀 @AstroSpanner]

@SevernDweller @Mandlbaur @Ferrari_ball @messigoat1899 @Scotty_D_J OK, that fixes the "how".

He won't, because of my points b and c.

[Will Grainger 🐀 @AstroSpanner]

@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

[Will Grainger 🐀 @AstroSpanner]

@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.

[Will Grainger 🐀 @AstroSpanner]

@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.

[Will Grainger 🐀 @AstroSpanner]

@DJSnM @Dylan_Morri They can be used as teaching examples... https://t.co/9DKnSCycVx

[Will Grainger 🐀 @AstroSpanner]

@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.

[Will Grainger 🐀 @AstroSpanner]

@Scotty_D_J @Mandlbaur @messigoat1899 You can see from this thread (https://t.co/ZgbRcBELV9) that others have tried to explain this to him

[John Mandlbaur @Mandlbaur]

@MarshallRites @Debate_COAM There is no argument that the overall p will change in magnitude insignificantly from the tiny offset angle which is literally a straw you are grasping at. The argument is about the tangential component of the motion.

[Will Grainger 🐀 @AstroSpanner]

@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.

[Will Grainger 🐀 @AstroSpanner]

@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.

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.

[Will Grainger 🐀 @AstroSpanner]

@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.

[Will Grainger 🐀 @AstroSpanner]

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

[Will Grainger 🐀 @AstroSpanner]

@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.

[Will Grainger 🐀 @AstroSpanner]

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