Why We Get Dizzy (…and Astronauts Don’t)

From BrainCraft:



More at Popular Mechanics:

When an astronaut first gets onboard the ISS, they feel constantly dizzy because the fluid in their inner ear is floating around in zero-g instead of staying put like on Earth. After the first couple of days, their brain adapts by essentially ignoring signals from the inner ear in favor of inputs from the eyes. Once that happens, it becomes very difficult to force the brain to start paying attention to the inner ear again.

Thermodynamics and chemistry: The Science Of Barbecue

Joe Hanson of It's OK To Be Smart (youtube channel) and Aaron Franklin, the owner of Franklin Barbecue in Austin, Texas discuss the thermodynamic and chemical science behind grilling meat.

In this week's video, I stop by the #1 BBQ joint in America (seriously, you can look it up) to learn about the science of BBQ!

By the way, here's Aaron Franklin brisket recipe and here's his series of video barbecue lessons. From his comments:

The science behind these things: how wood burns, how airflow works, if you start thinking of how fluid dynamics work inside the barbecue, science has a pretty huge part of it. I think good barbecue is a balance between science and gut instinct.
