As a fluid mechanician, I am, naturally, saddened (but not surprised) at the lack of mention for the Navier-Stokes equations. What perplexes me is the absence of Newton’s second law, force = mass x acceleration, which is so fundamental to majority of physics experienced in everyday life.
Physics are supremely awesome, guys.
What confuses a physicist? A viewer asks our team of physicists and astronomers what part of science they find most confusing. (via Fozzy)
Can you imagine a religious person expressing his or her doubts like that?
This is quite a brilliant look into real science and real scientists. Most of science is not having the answers, and, for all of us, there’s always some subject that we just don’t get. I suspect in my field, if asked this question, there would be a lot of people answering with “turbulence,” even though many of us have or do work on it! Some aspects of nature are just so complicated that they’re beyond our current grasp, but that doesn’t stop us from reaching!

Proof that physics are always cooler in micro-gravity.
“Why the spectacular spray of vapor around the plane? Engineers believe droplets of water form from moisture in the air around the plane as it speeds by, creating a drop in air pressure around it.”
Is it just me, or does this quote make it sound like the water droplets cause the pressure drop? This might make the physics clearer: “The vapor cone forms when the pressure drop accompanying the acceleration of the air around the craft to supersonic speeds causes the water vapor in the air to condense.” But that’s probably too complicated sounding…
