The Mathematics of Poker. Poker is a mathematical game, and itâs a game of incomplete information. That may sound complicated, but it really isn't. On a very basic level, winning poker starts with the selection of which starting hands to play.
The difference between the electric potential at two points, A and B, is measured in volts and called the Potential Difference. However if you connected a resistor between points A and B, no current would flow. Now consider you battery, with the same voltage across its terminals as the PD between A and B above.
In the Standard Model, the weak and electromagnetic forces are two aspects of something called the `electroweak force', which is described by the group . Curiously, it turns out that the familiar concept of `electric charge' is less fundamental than the concepts of `weak isospin' and `hypercharge'. The weak isospin of a particle describes how it transforms under , while its hypercharge describes how it transforms under . The electric charge is computed in a funny way from these two! In the following problems, you will examine how this works.
