Finding your way around Cooper Science Complex can seem complex to those new to the building. It consists of three different building codes -CL, CN, and CP- but the room numbers are consecutive and non-repeating (ie there is only one room 267 despite there being three different buildings).
CL = Cooper Life (Geography, Physiology & Health Science, and Biology reside therein)
CN = Cooper Nursing (School of Nursing and the Science-Health Science Library)
CP = Cooper Physical (Chemistry and Physics & Astronomy)
The simple solution to finding your way around Cooper is to stop by the Science-Health Science Library (SHSL) ask the staff where your classroom is and pick up a copy of enhanced floorplans.
OR you can visit the SHSL website and download the floorplans (PDF) for yourself: http://cms.bsu.edu/sitecore/shell//-/media/WWW/DepartmentalContent/Library/ScienceHealth/SHSL_cooperfloorplans.pdf.

|80m hole in Siberia|
~Was it a meteorite? An explosion from underground due to secret Russian experiments? The rupture of a tunnel leading to the inside of our Hollow Earth? UFOs?~
Most likely, this was the eruption of an unusually large "pingo."
Pingos (aka hyrdolaccoliths or cryolaccoliths) are formed in periglacial regions where permafrost exists and can be thought of as a slow, cold geyser not unlike Old Faithful in Yellowstone. Instead of geothermal processes, pingos

The crater in Siberia matches this criteria perfectly: there is even a lake of ice water at the bottom of the shaft under the crater that is about 230 meters deep. This is consistent with the definition of a pingo.
Closed-system pingos are ones that have not yet ruptured and appear as a mound or hill on the surface. Open-system pingos are ones that appear as craters or lakes inside of craters. The Siberian hole seems to be an extremely large pingo 80 meters across that did not form a lake but opened to reveal the cylinder hollowed out by groundwater and the lake of ice water at the bottom.
It's an unusual and strange landform to those of us in more equitorial climes but they are fairly well-known in northern latitudes and far more interesting than those explanations listed above.

So, when exactly do we reset our clocks? And is it forward or backward one hour?
Daylight Saving Time can be very confusing. Read below to help end your confusion! [The chart on the left plots the times of sunrise and sunset (with DST adjustment as separate lines) in Greenwich, GB for 2007.]
Short answer: For the Spring- On Sunday, 09 March, 2014 at 2:00am, you should set your clock forward one hour to 3:00am.
For the Fall- On Sunday, 02 November, 2014 at 2:00am, you should set your clock backward one hour to 1:00am. (Remember "spring forward, fall back...").
Easy answer: Most people who go to bed earlier than the wee hours of the morning simply set their clocks back/forward one hour before they go to bed on Saturday.
