Would it be easier to moonwalk on the moon? No, it would be the same as on Earth. Slate’s The Explainer is wrong.
Basically, Hancock gets upset with this boy and throws him in the air to scare him or something. In case you did not time it, the kid was in the air for 23 seconds. I claim that in order for Hancock to throw a person in the air for this long, the acceleration during throw would be deadly.
I have already talked about science and why everyone should take some science courses. The short answer (in case you don’t want to read the previous post) is that everyone should take science because science (along with art and other stuff) is what humans do.
So, tomorrow I will be off to attend a workshop [...]
Was the moomwalk fake? No, not the Apollo landings. I am talking about Michael Jackson’s moonwalk. You got to admit, he had a big impact on a lot of stuff and this is my way to give him respect – physics.
I made this screen cast for my algebra-based lab. Maybe you will find it useful also. This is a tutorial using Tracker Video Analysis (an awesome free program as I have said many times). In this tutorial I analyze a moving cart that shoots a ball up and lands back in the [...]
The internet sure can bring some awesome stuff. Chad at Uncertain Principles has a great post about the vision of elves. He refers to a part of The Two Towers where Legolas can count the number of riders of Rohan from a great distance.
Not only is the post great, make sure you read [...]
This was on my ‘to do’ list, but Tom at Swans on Tea beat me to it. Basically, this grocery store has these plates that when depressed produce electrical energy. Tom does a good job pointing out that this is not free energy (the original article says this also). Clearly, the energy comes from the cars. How much would this cost the cars?
I don’t know why I even suggest a new energy source. Fusion power is only a few years away in the future (just like it as always been). This will replace any other sources of energy that we could come up with. But, I can’t help myself, I need to share my idea and save the world. It’s what I do. (call me a superhero is you want).
We can get all of our energy from the rotation of the Earth.
I don’t really know why these guys are putting explosive on sledge hammers. Sure it looks fun, but I think I would pass. Anyway, here is the part I was curious about.
I have been wanting to look at this whole curved bullet thing, but I wasn’t sure how to approach it. In case you are familiar with the myth, this is from the movie WANTED (which I did not see). Apparently, some people learn how to make bullets curve by moving their gun. Here is a shot of a bullet curving in front of someone.
