Happy g day
Posted by Rhett Allain on September 8, 2010 Actually, it should be called Happy “Magnitude of the local Earth gravitational field” day. You know, 9.8 N/kg on September 8 (9/8). Get it? Well, the idea was for the physics students and faculty to build some stuff to do outside – projectile motion type stuff. Well, we had the idea a while ago and…
What is this #2: Answer
Posted by Rhett Allain on August 31, 2010 Reader Fruity was the first to correctly name this device – on just the 9th comment. Impressive. Honestly, when I found this thing I had no clue. I asked other physicists and none of us were sure. However, I did find the answer. Let me show you my secret. I don’t know how old this…
Variation in throwing a ball
Posted by Rhett Allain on August 24, 2010 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…
Pouring tea in a plane – upside down
Posted by Rhett Allain on August 17, 2010 Let me start with the video. Here is a guy flying a plane in a barrel roll and pouring some tea at the same time. Talk about multitasking. How can he pour upside down? Well, there are two ways to look at this. First, I can look at this in the frame of the plane.…
Basketball shot – real or fake?
Posted by Rhett Allain on August 7, 2010 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…
Mercedes Roll
Posted by Rhett Allain on July 13, 2010 Here is a commercial for some Mercedes car. The first part is quite boring, but check out the stunt at around 2:00 minutes into the video. I haven’t bothered to check if this is officially fake or not. Instead, I will do what I do – see if this is even feasible. The common question…
More Dangerous Kids
Posted by Rhett Allain on July 11, 2010 My car had a flat tire. When you get a flat tire, you might as well make something useful of it – right? As I was jacking the car up, I had a great idea. Use this for one of my “Spoof Science” videos. The only problem is that this takes a ton of work…
Chased by a Zombie
Posted by Rhett Allain on July 1, 2010 Title: Chased by zombies When I heard word about the ScienceBlogs Zombie Day, I knew I wanted to participate with a post – but I had no idea what to do. My first thought was to somehow talk about living off the electric grid in the case of a zombipocolypse – you know, like how…
Kids like demos
Posted by Rhett Allain on June 27, 2010 Sometimes I get asked to do some demos for kids. I like this, it is fun. This week, I was asked to do just such a demo. Kind of as a historical record, I am going to document what I did. The audience It is always important to think about who you are talking to.…
What is Arnold made of?
Posted by Rhett Allain on June 21, 2010 Of course I am talking about Arnold Schwarzenegger. After looking at how many bullets he carries in Commando, I remembered this scene (also from Commando) (warning: maybe some not great language and some killing. You have been warned) If you don’t want to watch that clip, here is a shot (sorry for the quality). Clearly…
