Enlightenment Two videos came out (Veritasium, Dialect) about measuring the one-way speed of light. Both are the usual fare for science videos, though Dialect is on the spicy side. For a bit of primer, the one-way speed of light is the distance traveled per time taken between two points. The two-way speed of light is the round trip distance traveled per time taken between two points. The aforementioned videos claim we cannot actually measure the one-way speed of light....

Shoots (Snakes) and Ladders Shoots and ladders is the classic game for kids 1. The rules are simple. Each player starts with their pieces starting at the start of the board. For each player’s turn, they role a six diced dice where the rolled number is the number of spaces to move forward. To win, you must be the first player to reach the end of the board. For simplicity, we will consider reaching the end as rolling enough to move past the last position....

The Universal Number (As of current knowledge) every possibly measurable quantity can be represented with $10^{134}$ bytes (or bits). Why? First, I would like to make some assumptions! Let’s same you make a measurement to distinguish the physical states of the world. For example, a potato could of many lengths! We use rulers to distinguish which universe1 we are in such that the potato is so long. Effectively, the smallest length increment is the Planck length....
