Google Funding the Next Big One?

The Grey Mouser Re:Unfair Blame to Both Google And AltaRock (295 comments)

No, assert(0) is correct: the total energy of a quake varies as the 3/2 power of the seismic moment. Both the Richter and Moment magnitude scales are based around the base-10 logarithm of the seismic moment, but that isn't the same as the total released energy of the quake.

By the way, I noticed that this fact is mentioned in the second paragraph of the very link that you cited. Did you perhaps stop reading after the first? ;-)

Archimedes Death Ray in San Francisco

The Grey Mouser Re:That's what made it a great weapon of peace (361 comments)

Spreading rumours about Archimede's marvelous machines must have been a pretty good deterrent to invasion.

Sadly, it didn't work out that way. Archimedes was killed by a Roman legionnaire when the general Marcellus sacked Syracuse in the 3rd century BCE.

Or maybe the Romans took Archimedes devices as a challenge :-)
