Watermelon Collisions – ouch

Through random surfing, I found this clip from The Amazing Race (which is apparently some type of reality show). Don’t really know the set up except that it appears some girl is trying to launch watermelons with a slingshot. This looks bad, but she seems to not be seriously injured. Watermelon smashed on face. Wow.…

The Curving Soccer Ball

You can call it football if it makes you happy. Anyway, this is a popular story going around. The physics of the magic curving soccer kick. Here are two ends of the spectrum. First, there is the lower, easier to consume version from io9.com Physics forced to come up with whole new equation to explain…

What if everyone jumped?

Might as well jump. Jump. Go ahead, jump. – Van Halen Suppose everyone in the world got together and jumped. Would the Earth move? Yes. Would it be noticeable? Time for a calculation. Note: I am almost certain that I have done this before, but I can’t find where. Starting assumptions. 7 billion people. Average…

How tall is that UFO?

You know I wander around the intertubes, right? Who doesn’t? Anyway, I saw this collection of strange google Earth images. Yeah, it is kind of dumb, but this one made me think: That article said the image was from TechEBlog, so there is that. I have no idea what this thing is, but it is…

Variation in throwing a ball

I might as well make a new tag called “basketball throws” because I can’t stop with the analysis of these crazy basketball shots. Watch – in the end someone is going to post a video about how all these were faked (and I have said there is no clear evidence they are fake). Oh, if…

More basketball analysis

Reader Jorge has also looked at these amazing basketball shots. (here is my last basketball analysis) Jorge claims that at least one shot seems fake. He is referring to the following video (at around the 2:20 mark). ARRGH Ok, new plan. For some dumb reason, youtube won’t let me embed this video. Well, here is…

More on turning and braking

I can’t let it go. There is more here to explore. First, I can’t believe that I looked at braking and then turning but not turning then braking. And what about braking while turning? I will model braking and then turning – but it won’t stop here. Consider a few motions. I could turn and…

Some more info on basketballs

You know I have trouble letting stuff go, right? I am still thinking about these crazy long basketball shots. Here are some more thoughts. Really, there are two things I am interested in. First, commenter Scott Post suggests that the drag coefficient might be around 0.25 instead of 0.5. I don’t know. For the discussion…

Size of 91,000 documents

Here is a quick one. One of the big news stories recently was this regarding WikiLeaks and the release of the Afghan War Diary. There could be tons of things to discuss regarding this – but I am not going to do that. The first thing that struck my mind was “over 91,000 documents”. That…

Basketball shot – real or fake?

I have seen several videos similar to this. Real? Fake? How many tries did this take? Let the analysis begin. Before I do any analysis, let me state that I think this is not fake. I do not know that for sure, just my first guess. How would I tell if it is real or…
