Abstract
Are there some days when songs echo round and round in your head and you can't seem to turn them off? Perhaps you remember that classic song about a friendly "battle of the sexes". The man remarks that he can do everything best - but the woman replies that she is every bit as capable. When asked specifics, she always warbles in reply "Yes I can, yes I can, yes I can!" That may be. However if a competition were held between our technology and whale expertise under the sea, the whales would be easy winners.
