(suggested new terminology)

Definition. Two distinct primes p and q are said to be compatible fif 2g is not an integer, where g is their geometric mean, and the integer closest to g is a prime.

# Conjecture (odd power of 2; 3; Lagrange’s conjecture)

If n is greater than 2 and p is the largest prime less than n^2 and q is the smallest prime greater than (n+1)^2, and q – (n+1)^2 = 3, then n^2 – p is an odd power of 2.

# Acropolis

(suggested new terminology)

This is the the term I will use for the suite of Question-and-Answer (‘Q & A’) sites known as ‘Stack Exchange’. I will also use a different method for referring to an individual site, namely,

‘Acropolis/Subject’ for ‘Subject Stack Exchange’. So, for example, I will refer to the site ‘Mathematics Stack Exchange’ as ‘Acropolis/Mathematics’.

# OBSERVATION (big errors)

There are two big errors the unmalicious can commit:

1. Attending to theory instead of to urgent practicalities. (‘doing math in the cockpit’)

2. Partying instead of attending to theory.

Ludwig Wittgenstein famously noted error #1 (studying to become professional philosophers while war was raging)

Then there is the one error that the malicious commit: partying instead of attending to urgent practicalities. (‘fiddling while Rome burns’)
