11:14 AM | Eddy generation and optics.
Eddies. Dips in the surface and shadows on the ground. I always get really fascinated by watching how eddies are generated by obstacles in a fluid. But it is especially exciting when you don’t only see the eddies because you … Continue reading →

4:10 PM | #GulfSpillFlashback: Giving the Gulf Oil Spill the Consideration It Deserves
[php]On April 20, 2010, the Deepwater Horizon oil rig exploded in the Gulf of Mexico, setting off the largest accidental marine oil spill in U.S. history. As a result, April 20th of each year is the day to remember the lives taken by the explosion and consider the recovery of Gulf communities and wildlife. However, 3.19 million barrels of oil didn't burst from the well in a single day—it steadily streamed out over the course of 87 days before an experimental cap stopped the flow on July […]

7:05 PM | Which way does an octopus crawl? Anyway it wants.
Let’s face it, octopuses are just going to be our cephalopod overlords. They have 8 arms, 3 hearts, Moms eat their own babies so the others can survive and they put Houdini to shame with their escape artistry. And now let’s just add to the list that they are way better at crawling than we will ever […]

Snails taste good. Well snails taste good to crabs. In fact almost every facet of certain snail’s lives is completely dictated by crabs. Crabs regulate populations of snails.
