Chasing Mummies is kind of like a cross between the reality showness of Deadliest Catch and History’s Mysteries. I like these kind of shows. My kids like these shows. It’s win-win. The basic idea of this show is to follow this dude, Zahi Hawass- he is like in charge of all the Egyptian museums. Here…

Where is the Maths Department?

I was having a discussion with my father about the budgetpocalypse for universities. I don’t know how it came up, but he asked: “What college is the department of Math in?” At Southeastern Louisiana University, the Department of Math is in the College of Science and Technology. Here is a paraphrase of our conversation. Me:…

Why would I think that?

So suppose you saw something that looked like this: This is a ball shot out of a shooter device. Well, it is a vypthon animation of a ball. What would you do if you came to see this video? If I had not made it, I would say it is an unrealistic video. It does…

Pumped up over triangles

I meant to mention this earlier since it happened a little while ago. There is this “mini-conference” with three schools: Southeastern Louisiana University, Southern Mississippi University, and the University of South Alabama. The purpose is to give students (and some faculty) a chance to present their work at a smaller conference. I really enjoy this,…

Bloggingheads Diavlog

The kind folks over at BloggingHeads TV were nice enough to offer me an opportunity to discuss some science stuff with Ed Grabianowski from io9.com. Here it is: In this discussion, we talk about: Learning physics and physics education research The value of science educators Good and not so good science on TV Journalism and…

Science Fair for Mere Mortals

After judging the science fair last week, I would like to revisit my tips for you the science fair participant. Warning number 1 Some of the things I say here might go against what your teacher has told you. I am not sure what you should do in this case. Your teacher gives you a…

RP 12: Some things about science

I have been meaning to write about this for quite some time. Really, I wanted to reply to Chad’s article on science at Uncertain Principles, but you know how things go. So, here are my key and interesting points about science in random order. Science is all about models (not ball bearings) Science is about…

Some time ago, I wrote about the awesome things the Greeks did in astronomy. Basically they calculated the size of the Earth, distance and size of the moon and distance and size of the sun. The value obtained for the distance to the sun was a bit off, but still a bang up job if…

One of things I like to think about in science is “how do we know that?” It is interesting how one thing builds on another. This is a story of how the Greeks estimated the distance from the Earth to the Sun (an important idea in the development of the model of the solar system).…

Spectroscopy and Collimated light

There was a question from Jerry in a previous post: “A simple question for which I can’t find an answer: Why do you have to collimate light spectroscopy? What would happen if you didn’t collimate it?” The basic idea of spectroscopy is to look at the different colors of light coming from some source. Typically…
