Experimental high-energy physics, namely neutrino physics at Fermilab.

2017 Eclipse

Lots of people gathered in the Quad today to watch the eclipse.  Lots of fun had by everyone.  Work crawled to a standstill in the name of SCIENCE.

We eagerly await news from the group that went south to see the Totality.  Did crickets start chirping? Did birds roost? Did cannibalism start before or after the plague of frogs?

Physics Hour – Friday 4:30 Starring Keegan Orr



presents Keegan Orr presenting his summer work…

The Design and Plans to Regulate an External Cavity Diode Laser by a Pressure Tunable Interferometer

Understanding the basic design and functionality of an external cavity diode laser (ECDL). Including how an ECDL would be regulated by a pressure tunable Fabry-Perót interferometer and the design of that device.

Science 205 at 4:30 PM on Friday.  Refreshments will be served.  All are welcome, even if you didn’t understand any of those words!  We’ll feed you anyway.

Physics Hour, 4:30 Sept 26

A week from today, the Otterbein Physics Hour proudly presents….

summer-reasearch-flyerwherein Tyler will explain how to “apply group theory to better understand the dynamics of quantum systems, then usie this improved understanding to better models of opto-mechanical systems”, based on his summer work in Utah.

Come learn what that means! All are welcome. Refreshments will be served. Come and hang out and listen to the dumb questions professors ask when they don’t understand something.

P.S. Department chairs, please forward to your respective departments!

Neutrinos and Egg Sandwiches

Because people have been asking about it after Brad Goff’s talk on Monday, here’s a little monograph I wrote as graduate student on the estimation.  Please forgive some typos and grammatical mistakes – I was still wet behind the ears….

It’s also worth noting I only calculated the neutrino-electron cross-section, and only for CC interactions with solar neutrinos.  There is also a substantial electron-nucleus cross section, but it’s probably not a huge correction… I stand by this estimate. Douglas Adams was prescient.
