Alpha, the first letter of the greek alphabet. Imagine the number zero, but on the right side, directly in the middle, a straight line extends nearly tangential to the zero, on a slight angle upward and to the right. In the same place, below, another line curves downward and to the right. Imagine a zero and a backward letter J fused together.
