If You Can Explain What Happens When Smoke Comes Off A Cigarette, You'll Get A $1 Million Prize

Believe it or not, there's very little known about fluid flows. However, understanding this phenomena is so important that if you can solve the equations that describe what happens when smoke comes off of a cigarette or when cream is stirred into a cup of coffee, you can win a million dollars. The Navier-Stokes equations are among the Clay Mathematics Institute Millennium Prize problems, seven problems judged to be among the most important open questions in mathematics. Solving one of these prob...
