Non-newtonian fluid

This is a video of me running across and sinking into a tub of non-newtonian fluid made from cornstarch and water.

Waterfalls running upwards

The tables have been turned in the energy and momentum battle between air and water. Air got tired of being pushed out of the way and decided to take it no longer.

Surface tension at work

More waves

An oldie but a goodie, this video is pretty awesome. I would love to have temperatures like this for one day this month.

Cool wave machine

I don't know what they're saying, but I can see that they have spent a whole lot of cash in order to better understand waves. Pretty important if you live on an island in a volcanically active area surrounded by unstable faults.

New post

So basically algae takes advantage of the no slip condition to propagate and flourish on rocks that are under the surface of a stream and thus creating a slip condition for the rest of us?

Shuttle Launch

I made sure I was around the TV to watch the final launch of the space shuttle Atlantis. Fox has freakin cameras on it and you could see the curvature of the Earth from it 3.5 minutes after launch. It reached velocities topping 10000 ft/s at an altitude of around 350,000 ft. It accelerated the entire way. Probably don't have enough computing power in my departmentally approved calculator in order to fathom the power it takes to accelerate that much mass that quickly. At one point it traveled about 10 miles in under 30s. Simply amazing.

Now we just lost the main fuel tank that the camera was attached to and got to see the shuttle separate from it with the curvature of the Earth in the background. You could see some gaseous fluid moving across the wing that was in view. The engines had already been shut off so I imagine I was viewing some rarefied air high on the edge of the atmosphere. Simply amazing.
