In which John Green teaches you about population. So, how many people can reasonably live on the Earth? Thomas Malthus got it totally wrong in the 19th century, but for some reason, he keeps coming up when we talk about population. In 1800, the human population of the Earth passed 1 billion, and Thomas Malthus posited that growth had hit its ceiling, and the population would level off and stop growing. He was totally right. Just kidding, he was totally wrong! There are like 7 billion people on the planet now! John will teach a little about how Malthus made his calculations, and explain how Malthus came up with the wrong answer. As is often the case, it has to do with making projections based on faulty assumptions. Man, people do that a lot.Crash Course is on Patreon!

Now that we’re done with the planets, asteroid belt, and comets, we’re heading to the outskirts of the solar system. Out past Neptune are vast reservoirs of icy bodies that can become comets if they get poked into the inner solar system. The Kuiper Belt is a donut shape aligned with the plane of the solar system; the scattered disk is more eccentric and is the source of short-period comets, and the Oort Cloud which surrounds the solar system out to great distances is the source of long-period comets. These bodies all probably formed closer to the Sun and got flung out to the solar system’s suburbs by gravitational interactions with the outer planets.Check out the Crash Course Astronomy solar system poster here: http://store.dftba.com/products/crashcourse-astronomy-poster--Chapters:Introduction: Where Do Comets Come From? 00:00Kuiper Belt, Scattered Disk, and Oort Cloud 2:52Long-Period Comets come from the Oort Cloud 4:03Short-Period Comets come from the Scattered Disk 4:27Pluto, Plutinos, and other Kuiper Belt Objects 4:47Oort Cloud Objects 8:25Review 10:38--PBS Digital Studios: http://youtube.com/pbsdigitalstudiosFollow Phil on Twitter: https://twitter.com/badastronomerWant to find Crash Course elsewhere on the internet?Facebook - http://www.facebook.com/YouTubeCrashCourseTwitter - http://www.twitter.com/TheCrashCourseTumblr - http://thecrashcourse.tumblr.com Support CrashCourse on Patreon: http://www.patreon.com/crashcourse--PHOTOS/VIDEOSHD Long Exposure Star Timelapse https://vimeo.com/34172172 [credit: Jeffrey Beach, Beachfront B-Roll]Fine Structure in the Comet’s Jets http://blogs.esa.int/rosetta/2015/01/16/fine-structure-in-the-comets-jets/ http://en.wikipedia.org/wiki/Protoplanetary_disk#mediaviewer/File:Artist%E2%80%99s_Impression_of_a_Baby_Star_Still_Surrounded_by_a_Protoplanetary_Disc.jpg [credit: ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA]Artist's impression of a protoplanetary disk.

This week Craig Benzine explores the leadership structure of congress. We’ll break out the clone machine to examine the responsibilities of the speaker of the house, the majority and minority leaders, and the majority and minority whips in both the Senate and the House. As the leadership heavily influences assignments to committees and acts as the primary point of contact with the media, they wield significant power in influencing public dialog.
