EINSTEIN EXERCISING HIMSELF IN CRIMESTOP

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 »

1.75 PRIMALITY DIVISOR , IS DESIGNED TO SELECT PRIME FROM NON PRIME IN THE 36SET SIEVE POSTED EARLIER 
  The 36 set sieve isolates all primes and pseudo primes, so far it seems that this differentiates and we can build up the sets of primes completly because all other numbers are sieved out. It is NOT a primary sieve for primality, which may come. Understand that we did not have a chance to thoroughly check this... 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 »
