Re: [math-fun] Bathtub drains

Quoting Dan Asimov <dasimov@earthlink.net>:

Long ago I read that water draining from a bathtub swirls one way in the N. hemisphere and the opposite way in the S. hemisphere. (Something about Coriolis forces.)

But since then I've heard a number of times that this is just a myth. Does anyone know which is really true? (Perhaps it depends on the precision of your equipment?)

Or of your bathtub ... Cyclones, tornadoes, whirlwinds work that way. But they have lots of space in which to work. Bathtubs probably depend more on the plumbing, given their relatively small size. - hvm ------------------------------------------------- www.correo.unam.mx UNAMonos Comunicándonos
