Skip calculator = win

First, where does Chad come up with these links? Oh, I am talking about Chad from Uncertain Principles. In his latest links of the day, I found this: Skip Class Calculator What a great idea. Basically, you enter some info about the class – like how often it meets, how many classes you have skipped,…

Arduino Physics

This is so awesome – an arduino controlled fan cart. If you are not familiar with the arduino, basically it is just a very simple and cheap programmable chip. I have been meaning to play around with one of these, but really I am afraid. Afraid I will like it just a little too much.…

And there’s parliament. Ok – sorry, I had to make a “Tom (Swans on Tea)” title for this one. Tom, forgive me. Here are two great circular motion videos. First, this one is from Dale Basler. He made himself a fine little floater-type accelerometer. Better than just make it, he made a video of the…

Blue laser awesomeness

Yes, green laser pointers are cool. Especially when you use them to make stuff fluoresce. Ok, what about a blue laser pointer? They are getting surprisingly cheap (Amazon has a 10 mW for pretty cheap). Still not cheap enough for me. But, you know what? Some of the physics majors here at Southeastern Louisiana University…

Hug a Laser

It is my duty as a blogger to mention lasers in this time of international laser celebration. This May is the 50th anniversary of the first lasers. Everyone knows a laser that they love, right? We all use them. So, instead of talking about lasers, I am going to post some great links to other…

Some People Running

This video seems like it is getting popular, but maybe that is because it is so awesome. Maybe it is just me, but I find this video very visually satisfying. I love the way they compare the different runners. Anyway, there is some physics here. Commenter Ben sent me the link to this video (thanks!)…

If you have been on the internet, you surely have seen this website showing the sizes of different starships. Way cool. Here is a small sample – but it doesn’t do the site justice. You really need to go browse around. Of course, I can’t let something like this just go. One of the things…

Oak Trees are awesome

In this part of the world, we have oak trees. Technically they are called live oaks – but I don’t get it. Of course they are alive. I was at a soccer game and this is the tree I always look at. Look how far those limbs extend horizontally. That branch is about 12 meters…

Diver in a bottle

I am surprised at how many people (chemistry faculty included) have never seen this demo. (oh, technically it is called a cartesian diver demo) Basically, you put some floating object that has an air space in a closed bottle of water. When you squeeze it, the diver goes down. For my setup, I used a…

Some time ago I was looking for materials to possibly build a foucault pendulum. Of course the first step is google. There was a site that suggested two old issues of Scientific American, and it happens that we have tons of old Scientific Americans in the store room. I found the two that I needed.…
