Is there a math problem that Cannot be solved?

The Collatz conjecture is one of the most famous unsolved mathematical problems, because it’s so simple, you can explain it to a primary-school-aged kid, and they’ll probably be intrigued enough to try and find the answer for themselves. So here’s how it goes: pick a number, any number. If it’s even, divide it by 2.

What is the toughest math problem?

Today’s mathematicians would probably agree that the Riemann Hypothesis is the most significant open problem in all of math. It’s one of the seven Millennium Prize Problems, with $1 million reward for its solution.

When did CQ take it to the field?

Plus, our “CQ Classic” series looks back at “taking it to the field” in 1945, with a reprint of an early article on building a two-tube walkie-talkie pack set for use in WERS, the War Emergency Radio Service, which kept some hams on the home front on the air during World War II.
