"harmonics".  And yes, a square wave has only the odd ones.  There are still
an infinite number of them (for a perfect square wave).  

Perhaps if you had some curiosity in fields outside your specialty you would 
have come across the fact that there are an infinite number of positive odd 
integers, just as there are an infinite number of positive integers.
