The OU on food packaging (the letter U inside a circle) is the kosher symbol of the Orthodox Union. It is one of the most popular kosher symbols in the United States. Many Orthodox Jews who only eat kosher food will only buy products with this symbol.

There is, for example, a subatomic particle called the Âµ-meson. It is used in dealing with very small or weak measurements, such as the Âµ-ohmmeter, and in the measurement of wavelengths. I'm sure there are many more, but I think you get the idea. The term Âµ represents (usually) the extremely small or weak.
