Two Views on Gravity Part 2: Geometry


Posted By on Feb 20, 2010

Sometimes analogies just feel right. For instance, “as hard to find as a needle in a hay stack” is often a good way to describe trying to find a needed quote in a half-remembered book. The mental image and the actual task just fit. In physics, I sometimes feel like the hardest part is finding the perfect analogy that will make it possible for everyone in the class to visualize the concept I’m trying to explain. In...

Okay, so this is a bit off topic, but … There are a series of questions I keep getting, “How do you stay connected while you travel?” “What is your recording set up?” “What books do you…?” “How do you…?” So, I’m going to (in a desperate attempt to force myself to blog better) work on launching “Monday Must Haves” posts centered on answering these...

Earlier this evening I got an IM from a friend alerting me that this afternoon there had been a shooting at the University of Alabama Huntsville. Details are sketchy, but it looks like a faculty member who was recently denied tenure went into the biology faculty...

If you’re like me, you’ve been following NASA’s desperate attempt to free Spirit, and the ongoing roving of the rugged little Opportunity. These two rovers, with Captain Jack like habits of not dying, are in part the creation of Steven Squyres. Next week, on Wednesday night, Squyres will be giving a talk here at SIUE. Come give him a listen? Here are the details: Steven Squyres “Roving Mars: Spirit, Opportunity...

For the past couple of weeks I’ve been busy teaching particle physics to two very different populations. First I work with working with little kids through the Davidson Institute, going over the ins and outs of making atoms. Then I took on particles again with my physics for poets class at SIUE. Between the two, its forced me to do a lot of thinking, and has reminded me how annoying gravity can be. Here’s the problem:...
