I've noticed when running E85 (in this case race fuel, so guaranteed 85% ethanol) the exhaust has a sweet, almost fruity smell to it.

Do you know what causes that?

People will still ask the question after each major earthquake, but you've make sure I won't be one of them. So thanks!

I used the Baader-Meinhof phenomenon in a online discussion thread in my masters language aquisition course work.

The PhD. teaching the course called me out about how in the world does an 80s communist German terror organisation have anything to do with out discussion.

I sent her some links, and let her know she will being seeing those words in her life more frequently now.

It’s been a long time since a big earthquake struck Japan, considering how frequently they hit. The biggest one was about 12 years ago and it was the tsunami that caused the most loss of life. As for the earthquake in Haiti, it’s a failed state with no building codes.

And those samples are compared to samples of similar age throughout the world to get a clear picture of global atmosphere levels during any one time.

Greenhouse gas dating is done with ice cores—mostly from Antarctica glaciers. Those date back to at least 2 million years ago. Bubbles of atmosphere get trapped in the ice, which allows us to study ancient atmospheric composition during the growth and decline of various ice ages in the past. Radioactive dating is what we can use on fossils or certain types of rock. The other, easier form of dating is by the use of index fossils. Also, stratigraphy rears its ugly head to help date strata, and drive geology students mad.
