An Introduction to Cosmology by Sean Carroll

Note: Although you can no longer find these videos on YouTube, you can find them avail­able on this CERN web­site.

Sean Car­roll, a physics pro­fes­sor at Cal­tech, has a knack for mak­ing sci­ence pub­licly acces­si­ble. He writes reg­u­lar­ly for the blog Cos­mic Vari­ance, and you have per­haps seen him on the His­to­ry Chan­nel, Sci­ence Chan­nel, or The Col­bert Report. Yes­ter­day, he announced that five lec­tures he gave at CERN now appear online, and it all begins with an Intro­duc­tion to Cos­mol­o­gy, or the ori­gin and struc­ture of the uni­verse. Then come lec­tures on Dark Mat­ter, Dark Ener­gy, Ther­mo­dy­nam­ics and the Ear­ly Uni­verse, and Infla­tion and Beyond. The lec­tures (all nice­ly pack­aged togeth­er at Cos­mic Vari­ance) will appear in the Physics Sec­tion of our col­lec­tion of Free Cours­es Online.
