Physics Quiz: Accelerated Twins

Just about everybody has heard of the Twin Paradox in relativity: one twin becomes as astronaut and sets off for Alpha Centauri, the other remains on Earth at mission control. Thanks to time dilation, the two age at different rates, and the one who made the trip out and back ends up younger than the… Continue reading Physics Quiz: Accelerated Twins

Kid-Lit Poll: Fish?

We had a parent-teacher conference this morning with SteelyKid’s teacher at day care, who confirmed that she is the cutest and cleverest baby in the universe.

This seems like a good topic for a poll:… Continue reading Air Travel Poll
