Hi to all my physics students.

What happens to the people in space during the Govt. shutdown? NASA

How's your data? Don't forget your units!

School is over. Way to go to all my physics students and congrats to the class of 2014. Please stay in touch.

My first plan for the summer is a one week backpack trip into the Grand Canyon. No cell phones, no email, just lots of gravity and inertia.

Returned from 6 days backpacking in Grand Canyon. Earth really is 4 billions yrs old and fossils do exist. Science rules! Gravity works.

Just completed the #Thunderriver route in the #Grandcanyon. Tapeats Colorado river to #Deercreek, Esplanade and out.

Need help purchasing a #RoadBike looking at #Pinarello either the Rokh or Marvel.

@Linzee_rene this a great photo. I miss you all!
