in the comments on Steven Hawking's lecture ...
●My favorite is from Norse mythology where Thor, the God of thunder, drank ale from a magic horn that was connected to the sea. Thor was such a mighty drinker that he actually lowered the level of the sea and this is how the tides came about.
Of course the Norsemen didn't discuss how the tide came back in but anyone who has spent an afternoon drinking beer knows the answer to that.
:-) Damn... so that's why the sea has all that foam in it, eh
And that accounts for the salt!!
