All I kid you not, but Jarrah is ready to challenge the accepted value of Pi. He will defend Rene, no matter how stupid the claim is. You'll have to find it in the comments. www.youtube.com/watch?v=WL7Fv23VQKI  I shake my head in complete disbelief. TK |

Well, we could see this as another subject change. After following the radiation discussion over at UM (you know, the one where he was having a kinda/sorta civil 1v1 with Jay, but abruptlyly fled when being called on an ignorant claim where noone spoon fed him the formulae translation to support it), he's shot off in a new tangent, now the Apollo 1 astronauts are "victims" (in his twisted mind) on par with Rene and Kaysing. (that really bothered me)
And he still gets basic stuff wrong...partial pressure, suit vs cabin pressure, insulation vs fireproofing, pi, relativity...BTW, I don't know the details, but at some point there was a decision to combine a couple of pad tests with Apollo 1, which combined the pressure leak check with the 100% O2...I was under the impression it wasn't really planned that way in the checklists, maybe someone knows more here...
Edit...I just did a quick review of the accident report, and am finding nothing about removal of insulation from wiring in the spacecraft. There's discussion of Teflon, and it's fire resistant qualities. There's discussion of the ECU, and a history of leaks, and potential contibuting factors to the fire thereof. Nothing about removed insulation.
Is Jarrah getting (more) bad info?

Whilst I do look at his stuff, I have missed this Pi malarkey. Can someone precis for me? I am assuming Mr Rene had another theory?

Oh dear. This should be good.
If Mr Rene was so sure then the maths world is surprisingly quiet on this astounding discovery. Especially when you can try this yourself and test it and prove it. Maybe they did not like the fee?

A few years ago, on Dr Karl's Self Service Science Forum, there was a fellow called Donde who claimed that Pi had whatever value you assigned it. Thankfully I don't remember the details of his claims, but I'm sure that if you were game to search for relevant threads, you could find something.
He also claimed that it would be impossible to send spacecraft to the stars because we wouldn't be able to aim them accurately enough. The idea of steering the spacecraft after launch seemed utterly implausible to him.

Hmm... Well, I just estimated pi using a spreadsheet and a simple trigonometic method. My estimate matches the actual value to the first 9 decimal places. My value: 3.14159265342917 Actual value: 3.14159265358979 If pi is wrong, then so is sine, cosine, and Pythagorean theorem. |

In engineering we routinely perform operations that would require the value of pi to be accurate and precise far beyond Ralph René's claims. That is, it's so painfully easy to prove René's claim wrong here, I'm surprised anyone actually takes him seriously. In fact, I didn't even think René was serious about it; I thought he presented it as one of those curious proofs that seems to reach an absurd conclusion, but only because of some insidious error.
For example, if we design a rocket casing that's 4 meters in diameter, and then we use an arc-length method to place fasteners around the rim, the error in the value of pi in this case would amount to several millimeters. Which is to say that in engineering we routinely rely on the accurate value of pi to several decimal places beyond the "exact" value that René specifies. This would be highly noticeable in production.
The value of pi is easily and frequently confirmed empirically. To try to argue that it must "really" be something else borders on insanity.

Just had a nose at one of the recent offerings on light and shadows etc. Think he has just proven the moon as a decent reflector without realising. Comments on Hubble telescope are interesting, bring on the Pi bit I say.
Fall off and fill lights pt 1 should anyone want a gander.

It seems he is taking "NASA lies about everything" to the ultimate...and, in a twisted way, it's rather entertaining to watch. But still sad, wish he'd do something more constructive with the time and talents he has, as opposed to flailing against the real world.
He doesn't understand it, so it must be a lie.

Yes, and that is a thought I once expressed to him. He obviously has creative talent, and I believe if he set about serious study he could apply himself well in physics. Sadly, he has emotionally invested in his hoax fantasy so much that he will defend Rene regardless. It says a lot about his ego, and much about his insecurity as his little gang follow him around backslapping his every move. |

...... If pi is wrong, then so is sine, cosine, and Pythagorean theorem. "The sum of the square roots of any two sides of an isosceles triangle is equal to the square root of the remaining side." Of course, that's the Scarecrow version from The Wizard of Oz. |
