Reblogged from jtotheizzoe:

Love this video! So, engineers are basically superheroes?

It’s a great message to deliver to the young girls featured in the video, or really any young person interested in science, and now that I think about it, really any person at all. The powers of a superhero are within your reach, and thanks to science.

Features cute illustrations by Beatrice the Biologist, too!

Simulating a Wind Tunnel in the Garage

Shawn uses a wind tunnel app and help from a ski coach to analyze his ski aerodynamics. He then designs a low-drag helmet. Watch to see how big a difference it makes to the drag coefficient. Shawn mentions that it’s a free app, but apparently it may not be for long so you may want to try it soon.

If you’re wondering what this software is, it’s called Autodesk ForceEffect Flow. It’s an app available for the Apple iPad that you can get by following this link:

Stability and Maneuverability in the Knifefish

via fuckyeahfluiddynamics:

Animals often move in ways engineers find counter-intuitive. Take, for example, the glass knifefish, an undulatory swimmer that controls its motion through wavelike oscillations of its fin. One might expect the knifefish to move its fin so that a single continuous wave moves from one end to the other. Instead two opposing waves move down the knifefish’s fins, one travelling from head to tail and the other travelling from the tail forward. The intersection of these waves is the nodal point, and, by shifting the nodal point fore or aft, the knifefish can hover in place, move forward or swim backward. At first glance, this seems like a wasteful system since a significant portion of each wave cancels the other, but, through mathematical modeling and experiments with a biomimetic robot, the researchers found that the dual-wave locomotion increases both the stability and maneuverability of the fish. (Video credit: N.

Sci Guide with Jheni Osman - How was the Eiffel Tower built?

The Eiffel Tower was built for the World’s Fair in Paris in 1889 and was initially designed to be dismantled when the fair was over.

Construction began in 1887 when they laid the foundations by creating 2m thick concrete slabs under each of the feet. As two of the feet run alongside the river Seine engineers were worried water would creep in, so they created metal shoe structures which kept the French water at bay. A bit like a pair of welly boots.

To build the main body they shipped in 18,000 different parts that were prefabricated in a factory and they put them together on site at the banks of the Seine using a whopping 2.5 million rivets.

Construction was completed on 31st March 1889 and Gustave Eiffel was the very first person to climb ALL the 1,710 steps! It remained as the world’s tallest structure in the world for 40 years!
