Nonlinear Superdimensions?

isomorphismes:

I’m not the first person to say "ceteris paribus is a lie". What this aphorism means is that if you make a c.p. assumption in order to be able to think something through, then the conclusion you reach may be irrelevant to the real world.

Worse, because people generally don’t understand

fuckyeahfluiddynamics:

As young stars form, they often produce narrow high-speed jets from their poles. By astronomical standards, these fountains are dense, narrowly collimated, and quickly changing. The jets have been measured at velocities greater than 200 km/s and Mach numbers as high as 20. The animation above (which you should watch in its full and glorious resolution here) is a numerical simulation of a protostellar jet. Every few decades the source star releases a new pulse, which expands, cools, and becomes unstable as it travels away from the star. Models like these, combined with observations from telescopes like Hubble, help astronomers unravel how and why these jets form. (Image credit: J. Stone and M. Norman)ETA: As it happens, the APOD today is also about protostellar jets, so check that out for an image of the real thing. Thanks, jshoer!

Taking a week before I start my new job to get back into botanical illustration. I work at the Phipps COnservatory and their orchid and bonsai show started on the 17th. I was able to collect a few specimens that fell off while preparing for the show.
