I got tired of attacking ESPN Sport Science. Well, tired of attacking might not be the best term. How about, attack in a new way (here are my older Sport Science attacks). Check out episode 1 of Spoof Science: A couple of notes: Watch it youtube if you want the HD version Making videos takes…

Student Letters from the Future

I wrote two letters (for two different classes). These are letters from the students of the near future to themselves in the present. this first one is for a non-majors lab. In this lab, I let them turn in “informal” lab reports that they can then use on the midterm and the final exam. The…

Hydrino and good PR

This is amazing. I can’t believe that power companies are paying Blacklight Power money, but they are. I guess Blacklight Power must have great advertising. Ok, so what is this whole Blacklight-hyrdino thing? Honestly, I am not fully familiar with it, but basically this guy says that you can get energy by getting the electron…

More on the Giant Water Slide Jump

This Giant water slide video is extremely popular on the internets. Maybe you have not seen it (doubtful), then here it is: This is such an incredible stunt that the very first question that comes up is – fake? or not fake? From my previous analysis, I can say: Even though there is some slight…

Note: This is a repost from my old site. Time to move it over. First, what is different about motion on the moon and on Earth? Since the moon has a smaller mass in spite of its smaller size*, the moon has a smaller gravitational field. The gravitational field on the surface of the moon…

Ford F-150 vs. a Plane. Really?

Big trucks are not as popular as they used to be, but gas prices are going down so maybe this commercial for the ford F-150 will start showing up again: They say its a real demonstration, but it has seemed odd to me. (they also say this is a professional driver on a closed course…

Fake vs. Real Forces

In this post, I am going to talk about real and not real forces as well as the fake centrifugal force (if you don’t like the word “fake” you could replace that with “fictitious”) First, an example: suppose you are in a car at rest and press the gas pedal all the way down causing…

Amazing Blob Jump Launch Video Analysis

Can you believe it? Have you seen this video? Are you thinking what I am thinking? WOW. How could these people not follow my rules for cool internet video. Once again, here they are: 1 Keep the camera stationary. This way I don’t have to keep moving the origin in the movie. 2 Don’t Zoom.…
