What is a maser? Who developed it?
Maser produces electromagnetic waves which was developed by Charles H. Townes, James P. Gordon, and H. J. Zeiger
At Columbia University in 1953, Charles H. Townes, James P. Gordon, and H. J. Zeiger created this maser.
By amplification, the Maser generates the sound of electromagnetic waves.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
