Introduction to Number Theory Learn the fundamentals of number theory from former MATHCOUNTS, AHSME, and AIME perfect scorer Mathew Crawford. Topics covered in the book include primes & composites, multiples & divisors, prime factorization and its uses, base numbers, modular arithmetic, divisibility rules, linear congruences, how to develop number sense, and much more.
Wow what an amazing idea to teach the history of the atom to students with learning difficulties. Not only the atom but this method of teaching can be applied to any number of teaching topics. I've also incorporated this activity into my Atomic Theory Lesson, link in the article.
The age of the universe and its vast number of stars suggests that extraterrestrial life should be common. If that’s the case, then where is everyone? In this infographic we explore some possibilities, ranging from the Zoo Hypothesis to the Technological Singularity
