Mathematicians are interested in solving problems.
• Goldbach’s Conjecture• Josephus Problem

Goldbach Conjecture (1690 - 1764)Is every even number > 2 the sum of two primes?
6 = 3 + 3 8 = 3 + 5 10 = 5 + 5
12 = 7 + 5 14 = 7 + 7 16 = 11 + 5
True up to 1,000,000,000,000,000,000
1960’s Chen proved that every even number > 2 is the sum of a prime and a product of two primes
n = p + q.r, some primes p, q, r.

Josephus Flavius• Josephus, an ethnic Jew and priest fought the
Romans in the Jewish- Roman War of 66-73 as a military leader in Galilee. After the Jewish garrison of Yodfat fell, the Romans invaded, killing thousands; the survivors committed suicide.
• In circumstances that are somewhat unclear, Jospehus found himself trapped in a cave with forty of his companions. The Romans asked him to surrender, but his companions refused to allow this. He therefore suggested a method of collective suicide: kill each other, one by one, counting to every third person.

• Jospehus then went and joined the Roman army went to Rome and became a historian of the Roman-Jewish wars.
