Reader Jeff wants to know, "How far away can thunder be heard? What causes it?"
Thunder can be heard easily six to seven miles away, and occasionally as far as 20 miles away. The sound waves of thunder are the result of the expansion and contraction of air heated by lightning. Intense claps of thunder are caused by repeated lightning in a previously heated path of air.
Reader Pete writes, "How many senators have been elected President?"
Fifteen. For the list, please look in the extended entry.
Do you have a question for me? You can e-mail it. If I know the answer, I'll answer it. If I don't, I might make something up.

On the Senator-Presidents:
7 of the first 15 Presidents were Senators.
Only 8 of the last 28 were Senators.
And none since Nixon (Ford, Carter, Reagan, Bush 41, Clinton, Bush 43). That's a current streak of six "non-Senatorial" Presidents.
