Questions & Answers

Q: What are the base SI units?

The base SI units are kilogram, meter, second, candela, amp, mole, and kelvin. These units are used to describe fundamental physical quantities.

Q: Can the prisoners interact with each other after they are lined up with randomly assigned hats?

Yes, the prisoners can talk to each other before the game begins to strategize and come up with a plan. However, they can only communicate by guessing the color of the hat of the person in front of them.

Q: What is the best strategy for the prisoners to maximize the number of survivors in the hat game?

The best strategy is for the prisoner at the back to observe the colors of the hats in front of them and determine whether the total number of hats of a certain color is odd or even. This information can then be communicated to the next prisoner who can make an informed guess.

Q: What statement can the person make to guarantee that he will be owed $1,000?

The person can say, "You will either give me $1,000 or $10." This statement creates a contradiction because if the person gives $10, the statement is false, but if the person gives $1,000, the statement is true.

Summary & Key Takeaways

  • Physics Girl and Zach Weinersmith discuss SMBC Comics and the popularity of a comic about a math teacher.

  • They engage in a physics trivia game, answering questions about base SI units.

  • They then attempt to solve a riddle about prisoners and a logic riddle.
