"Tons" of Snow?

Three feet is a lot of snow. Heavy, wet snow.

How much, exactly? Here's a thought exercise: We have some friends in the deeply-affected area of the '013 Blizzard. Their driveway is about 100 ft. long x 6 ft. wide, and is currently covered in 36" (three feet!) of snow.

Quick assumptions: let's assume it's a regular rectangle, and let's say a cubic foot of heavy snow weighs about 15 lbs (7 kg). Thus, we have (100 x 6 x 3) = 1800 cubic feet, which weighs (1800 x 15) = 27,000 lbs. That's 12,000 kilograms, or 12 metric tons.

That's as much weight as five Ford F-150 pickup trucks, or about 10 elephants. Really.
(Time to call for a plow, maybe?)

Best wishes for safety and fast utilities service to those affected in the Northeastern U.S.

State of the (Scientific) Union

Did folks tune in to watch President Barack Obama present the 2012 State of the Union tonight?

Out of sheer curiosity, I downloaded the text to both the 2011 SoTU (Winning the Future) and the 2012 speech (An America Built to Last). Now, I’m no political pundit or news analyst - I’m a scientist. So, I thought an interesting game might be to see how certain scientific themes grew or shrunk over the past 365 ¼ days.

Here’s the breakdown I tallied:
(# of mentions per word in the text)

Oil – 2011: 2, 2012: 10
Energy – 2011: 9, 2012: 23
-------
Biotech / Biomed / Biofuel – 2011: 3, 2012, 0
Tech / technology – 2011: 12, 2012: 9
Science / scientist – 2011: 7, 2012: 2
Engineering – 2011: 3, 2012: 1
Research – 2011: 9, 2012: 4
Development – 2011: 1, 2012: 2
Nuclear – 2011: 5, 2012: 3
College / Universities– 2011: 12, 2012: 15
Chemical – 2011: 0, 2012: 1 (Unfortunately, it was used in a negative connotation)
Math – 2011: 3, 2012: 0
Health – 2011: 8, 2012: 5

Is there a take-home message to counting up words and relating them to the direction of the country? Perhaps not. Thematically, the two speeches were different: 2011 was more forward-looking and focused on education, business, and terrorism; while 2012 dealt with global politics, congressional reform, and taxes. 

But there exists notable declines in most science-related topics from last year’s speech to this one. Except, of course, on topics where economics and science often cross – substantial mentions of oil and energy.

Quizás, Quizás, Quizás

Coming soon: More blogging.  Ciertamente.


(Although this is a lame excuse to buy time, try to think of it as my shameful placeholder until I can resume more science writing...just to tease, think startups, oxetanes, and science linkage)


((I'm also hard at work on more Haystack stuff...stay tuned!))
