All simulations are programming. All programs have bugs (except for LaTeX--jk).<br /><br />I trust iron filings (mostly).Neil Guntherhttps://www.blogger.com/profile/11441377418482735926noreply@blogger.comtag:blogger.com,1999:blog-4188823222763071436.post-9242118233248606382010-03-03T15:22:00.446-08:002010-03-03T15:22:00.446-08:00I meant seeing in the sense of detecting photons. ...I meant seeing in the sense of detecting photons. In your image we detect the iron particles, which happen to be lined up along the magnetic field, so it is a visualization. In the aurora instead you detect photons from excited particles (see http://www.mostlycolor.ch/2007/06/hot-body-excited-particles-and-north.html), namely nitrogen or oxigen and nitrogen atoms excited by the collision of solar wind particles being funneled down and accelerated along the Earth's magnetic field lines. The movie is an animation and a good example of spinning a message for a good purpose.Giordano Berettahttps://www.blogger.com/profile/07676490672431958222noreply@blogger.comtag:blogger.com,1999:blog-4188823222763071436.post-63708899052100088232010-03-03T12:53:14.805-08:002010-03-03T12:53:14.805-08:00re: "we cannot see magnetic fields" Why ...re: "we cannot see magnetic fields" Why is this http://www.fi.edu/htlc/teachers/lettieri/magneticfields.jpg not "seeing" magnetic fields?Neil Guntherhttps://www.blogger.com/profile/11441377418482735926noreply@blogger.com
