Sport Science FTW!

Normally, it isn’t really news when a show doesn’t do anything wrong. I am making an exception for ESPN’s Sport Science. Here is part 2 of Sport Science trying to reproduce Kobe Bryant’s “jumping over a car” stunt. And here is part 1 (although part 2 is the only interesting part). See. I can get…

You see in my experimental determination of the location of the accelerometer in an iPod, I used two different iPhone apps. Let me briefly mention some of the free iPhone apps that give you acceleration data. AccelGraph: This is one of the apps I actually used. What do I like about it? Well, it can…

There are several free iPhone-iPod Touch apps that let you look at the acceleration of the device using the built in accelerometer. I was planning on reviewing some of these free apps, but I didn’t. When I started playing around with them, it was clear that I needed some way to make a constant acceleration.…

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,…

Check this out. So, the guy jumps from 150 feet into some cardboard boxes. Why are the boxes important? You want something that can stop you in the largest distance to make your acceleration the smallest. Here is my Dangerous Jumping Calculator. Basically, you put in how high you will jump from and how much…

A few blogs

I would just like to take this post and use it to promote some relatively new blogs that I like. Speaking of blogs, I think I have classified blog posts into 3 different kinds. Link aggregators. Chad at Uncertain Principles does this with his Links posts. These kind of blog posts are the glue of…

Repost Compost for Earth Day

I wasn’t paying attention. Earth Day is today. If I would have thought of this before, I could have done something awesome. Instead, here are some reposts related to the Earth and energy. They have been sitting for a while in my post-compost, so they are nice and smelly. Most of these deal with Earth-type…

18,000 lbs of cumulative force

I want to give ESPN’s Sport Science another chance. The segment on Tim Tebow didn’t really have any errors. I thought, cool – what about this one on Jason Pierre-Paul? Here is the clip. Oh wait, embedding is disabled. Ok – if you want to watch go here (the image is a link) The goal…

Physics Tips for Media

You probably already know how I feel about the “media” and their physics explanations (see attacks). Let me summarize the problem. There are a whole bunch of cool shows on tv that deal with sciency stuff – that is good. These shows then try to teach some science along with their demos and explosions and…

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…
