Thanks for the help, but [Wiki sez](http://en.wikipedia.org/wiki/Slip_(aerodynamic)#Forward-slip) you have this backwards. Who’s right?

Another question: Weather - On a hot day, the pressure rises. This seems counter-intuitive to me, as I’d expect the air to expand in volume, not pressure. But when you’ve got gas in a container and heat it up, pressure (not volume) increases. Is the atmosphere really just one big container?
