This is my favorite!
These videos of a storm trooper playing piano Star Wars music are surprisingly addicting to watch!

I've totally fallen in love with Zootopia, and this song. Check it out!
See the original article here. Plus, he has a fantastic basement. I want one of those!
Someone also made a gif of this one and it's amazing! I also enjoyed these 12 gif snow cats.
Remember the saber memes spawned from the new Star Wars trailer? Well THIS video out does them all!
Star Wars vs Star Trek
Both of these are completely amazing and *must* be seen!
Star Wars vs DC Marvel

Ever wanted to fill your co-worker's office with shipping peanuts?
Of course you have. But then you realized just how much work it would take (and how much a pain clean-up would be), and decided it wasn't worth the effort.
We came up with a better way. Here's how to make them think you've actually done it.
1. Roll of tape
3. Roll of paper
4. Packing peanuts
5. Small box with at least 3 flaps intact
1. Roll out a strip of paper horizontally along the bottom of the frame
a. Be sure to leave enough space for the tape to overlap the bottom of the frame so the peanuts don't spill out the bottom
2. Tape left, right, and bottom edges
3. Fill the box with packing peanuts
4. Open 3 flaps with the one at the bottom inside the paper
5. Pour peanuts in
6. Pat the paper to help 'settle' the peanuts to fill in the gaps so you don't see the paper backing
7. Roll out next strip of paper
8. Repeat steps 2-6 as necessary
9. To finish it off leave some slack at the top so it bulges out a bit
a. This helps to give some depth at the top so you can make a pile of peanuts at the top, aiding the illusion
1. Close the blinds - too much light bouncing around the room reduces the illusion
2. Stuff packing peanuts under door - blocks light as well as discovery that the room is actually empty by peering under the door
3. Rig paper 'tube' from door frame to back of door and fill with peanuts, spilling out when the door is opened
4. Place something heavy behind the door - gives resistance when the door is opened
5. Rig a waterfall of packing peanuts to spill out when door is opened
Thanks to Jim and Paul for masterminding the operation; double thanks to Jim for writing up the instructions, and to Chris for being a good sport!
This cat is totally adorable AND persistent! Plus, see this link here. I like the music it has better.
Check out the original article here. It's clear that this physics guy's excitement about the new movie is way off the chart! You'll have to go to the original article to see the screenshots, gif and graphs.
I don’t have many options when I get excited about an upcoming movie. Really, all I can do is to over analyze everything I see. It’s just what I do.
So here we go. In this post, I am going to look at that weird rolling droid as seen in the Star Wars VII: The Force Awakens trailer. As a reminder, I am going to useTracker Video Analysis—it’s FREE.
Rolling Speed From Angular VelocityThis droid probably has a name, but I’ll just call him R2 Rolling (because his top looks like R2 D2). There are two ways to estimate his moving speed – but both require some type of size. Since I already said he (or she) looks like R2-D2, let me assume the head is the same size. Wookepedia lists R2 has having a height of 0.96 meters. This means that his head diameter would be about 0.43 meters and the rolling droid has a ball diameter of 0.76 meters.
Now for the video. This first method assumes that R2 Rolling is indeed rolling on that ball thingy (and not flying or skipping or something else). If I measure the rotational speed of the bottom ball, I can use that to find his rolling speed.
Here is the plot of angular position vs. time for the droid. Note that I had to export the data from Tracker to Plotly because Tracker always displays an angle less than 2π.
From this, you can see that the slope of the linear fit is 16.1 radians/sec. That’s the angular speed of the rolling part of droid. If the ball rolls without slipping, then there is the following relationship between the velocity of the center of the ball and the angular speed (ω):
Using a ball radius of 0.38 meters, this gives a droid land speed of 6.118 m/s (13.7 mph). So, about the speed of a human powered bike (but not a professional cyclist).
Rolling Speed From Relative Ground MotionWhat about another method? In this second measurement, I am going to track the motion of an object on the ground relative to the droid. Using the same clip (and scale), this will give me the position of the droid.
Based on this, the droid has a linear velocity of only 4.17 m/s. That was the plot from the best piece of “ground” that I could see. For two other plots, I have a ground speed (and thus droid speed) of 3.65 m/s, 4.68 m/s, and 5.93 m/s. None of these speeds are quite as high as the speed I calculated from looking at the angular velocity.
So, why are the two droid velocities different? Honestly, they aren’t THAT much different. If you notice the speeds of things on the ground change. That’s because when an object on the ground is farther away from the droid, it has less apparent motion (same reason the moon seems to follow you when you drive). I suspect even the fastest moving part of the ground is behind the droid making it’s motion seem slower.
That’s too bad. I thought I would be able to show that this little droid isn’t rolling at all and instead spinning out or flying. In the end, I think he is indeed rolling. That means that this Star Wars trailer is probably real and not a fake.
Just for fun, here is the motion of the droid with the camera stabilized (this is something that Tracker Video Analysis can do for you).
That’s it for the rolling droid. How fast is this compared to the flying R2-D2 in Star Wars II? The rolling droid is faster. From my estimation (and video analysis), R2-D2 flies at about 2.2 m/s. I should also point out that R2-D2 flies incorrectly in Episode II. While moving at a constant speed, he should have his thrusters pointed down instead of back.
Yes, there will be more video analysis posts from the Star Wars VII trailer.
