EINSTEIN EXERCISING HIMSELF IN CRIMESTOP
|
| |
[link] George Orwell: "Crimestop means the faculty of stopping short, as though by instinct, at the threshold of any dangerous thought. It includes the power of not grasping analogies, of failing to perceive logical errors, of misunderstanding the simplest arguments if they are... more »

How to detect Statistical Anomalies (i.e. reported heights)?
|
| |
Usually, when I regress the frequency of heights of adult men to the actual heights, I get something which resemble a smooth bell curve. I use a sample size of 30-50, typically. However, today, I have a feeling that I'm analyzing spurious data sets, because my histogram is not a smooth bell curve, but in fact,... more »

PRIMALITY FORMULAS FOR OPEN REVIEW , INVERSE 19 MATHEMATICS
|
| |
This is for serious mathematicians. We already do have a placement Sets at 36 2/3 (5), 3/4 (7), 5/6(11) .6/7 (13) , 8/9 (17) should cover all pseudo primes/ primes fractions by the equations showed and there should be other divisors besides 1.75 and .7, ..11, .17 .13 . 5 The primality has to be solved... more »

Topos theory: axiom of choice implies a topos is Boolean
|
| |
Hi all, I'm reading Goldblatt's /Topoi: The Categorial Analysis of Logic/ and am stuck on how to fill in some gaps in a proof. The author claims that, if a topos E has the property that every epic arrow has a right inverse then E is Boolean, i.e. every monic f: a -> d has a complement in sub(d), the lattice of subobjects of d. To show this, let... more »
