aerodynamics / fluid dynamics question of drag & turbulence
When I was a young boy I thought the force of wind resistance upon a symmetrical object at the front of it would be roughly equal to the wind resistance at the back of it. But is that a universal rule? If an object that looks like two equal cones joined at the broad base is the projectile, will its ...

What is the most interesting concept?
Some think Einstein's theories of Relativity are the most interesting in science, perhaps because they're deemed counterintuitive. But are they the most interesting? Is string theory more interesting; or simply untestable clap-trap? The Big Bang, because it's fundamental? Or might psychology be the ...

What is the purpose of life?
You're welcome to distinguish objective from subjective here. But since this thread is intended to entertain the consideration of both, I haven't distinguished here. Some may claim that purposeful life presumes creationism. Others may feel their own good deeds are their own reward. But if cosmic hea...
