Albert Einstein

Someone asked if I knew Einsten. I knew of him (but he did not know of me). Besides being the genius that discovered the theory of relativity, Einstein was a peace activist and a strong socialist.

He was purported to have created a logic quiz, called the Einstein Intelligence Quiz. I saw this quiz 30 years ago, but could not solve it at that time. I learned how to solve this quiz recently and to create similar quizzes at various levels, including a more difficult level than Einstein's Quiz.

You can buy the TKL Intelligence Quiz books here. Enthusiast can buy volumes 3 and 4 in soft copy (PDF).
