8 shops in one Major metro area is hardly a representative sample.
And this statement has to have an impact on the data:
"The coffee shops were selected after visiting a larger sample of stores in order to evaluate which offered seating arrangements tha allowed for ready but inconspicuous observation of customer orders and service received."

Part of my job is teaching statistical sampling methods for variable and attribute analysis on parts and services.
I'd be embarrased to hand in a report saying "I observed and measured 8 pieces in 500 and only pulled pieces that were easy to reach."

of course if the "coffee shops" are only one chain then it might be a more reasonable sample. But my assumption after reading the report is that this is all coffee shops from Dunkin' Donuts to Starbucks to Seattle's Best to local Mom & Pop places.

He's probably counting cash in Euros because the dollar is falling so rapidly that it's more profitable to do business in Euros.

The euro has been the currency of choice for black markets (i.e. drugs and guns) for several years now. Originally, it was a matter of the euro being slightly stronger to the dollar, and the 500 euro note being smaller than the $100 bill. Thus, you could pack more "value" into a smaller container (suitcase). Recent commentators are missing the point that the use of a euro in a rap video may be more of a reference to drug culture than a comment on the relative position of the dollar.

Interesting article on dinosaur extinction -- the greenhouse gases definitely would've increased the length of the extinction event, and subjected a wider variety of species to stress.

But I think the authors are wrong to dismiss the asteroid impact as the primary cause.

The _really_ interesting theory is that the asteroid caused the volcanic eruptions.

Here's the idea: when the asteroid punched through the earth's crust, it caused a "ripple effect" on the opposite side of the world. Part of the crust was torn open, and giant magma flows poured out.

The evidence is that the volcanoes in question are neatly on the opposite side of the world from the asteroid impact, and they're a very unusual type of volcano that we don't see today -- giant flows of magma all at once, big enough to cover several of the Western states.

As a side note, the other interesting thing about this event is that it shows us what happened the last time a huge bunch of carbon was poured into the atmosphere. It's the most recent historical record of what happens when you dump carbon into the atmosphere. So global warming isn't pushing us into completely uncharted territory -- we do have this one other example to help us make predictions.
