never heard of an erlenmeyer flask outside of Jetpunk. It was just called a conical flask in my chemistry days. I think it's another US thing. on which subject what's a Graham cracker and why should anyone be aware of its existance?

yakdog is correct. A rigid dirigible has a hard metal frame, whereas a blimp is simply inflated like a balloon. If you have ever seen the footage from the Hindenburg Disaster you can see it has a large metal frame that supported it, which made it a rigid dirigible. I hope that helps answer your question (which I realize after writing this was from 4 years ago, haha).

As much as Zack Snyder gets bashed for some things, one thing I will give him credit for is that he is really good at making shots that look like they belong in a comic book. I think Watchmen might be my favorite Zack Snyder film, perhaps even his best.

Got everything but Venn, Sousa, Bowie and Gatling. Got Rorschach at the first try, to my everlasting surprise, and Kalashnikov on the second (wrote CH at first). I was very glad to be French when I saw Daguerre, Braille and Foucault, though! Nice quiz, I learned a lot with this one!

I believe that the Richter Scale measures magnitude whereas the MMI (Modified Mercalli Intensity) Scale measures intensity of earthquakes. The difference being magnitude measures the energy, intensity measures the effects.

So either Mercalli should be the correct answer or the word intensity should be changed for magnitude.
