    The Science and Grace of Auroras

    PBS Member Stations rely on viewers like you. To support your local station, go to: http://to.pbs.org/DonateOKAY ↓ More info and sources below ↓ The science behind Earth's nocturnal light showClick here to SUBSCRIBE, it's FREE! -- http://bit.ly/iotbs_sub Space might seem like an empty place, but the area surrounding Earth is constantly being bombarded by waves of charged particles released by the Sun: The solar wind. Luckily, thanks to Earth's swirling, molten core (and the magnetic field it provides), we are protected from this planet-sterilizing onslaught like an invisible force field All that science has a beautiful side effect: It makes the auroras! The Northern and Southern lights are the result of the solar wind and its dance with Earth's magnetic field and polar atmosphere. It's Earth's own cosmic light show!

    Could You Be a Chimera?

    PBS Member Stations rely on viewers like you. To support your local station, go to: http://to.pbs.org/DonateOKAY ↓ More info and sources below ↓ Follow me to MONSTRUM! https://youtu.be/x-GjSU4nOxE SUBSCRIBE so you don’t miss a video! ►► http://bit.ly/iotbs_sub Ever feel like you aren't totally yourself? Well, maybe you aren't. In this video, we explore the idea of human chimeras. In mythology, the "Chimaera" was a beast made from different animals combined into one. But in biology, a chimera is a single organism whose body is made from parts of two or more genetically distinct individuals of the same species. Biological chimeras were once thought to be rare, but modern genetics has shown us that these genetic mashups are so common, that you yourself may actually be a chimera. And even if you don't have part of another body in you, your body is certainly not just one thing. We also discuss the idea of mosaicism and how it relates to cancer, Tasmanian devils, and circus sideshow attractions. #genetics #chimera Special thanks to Dr. Emily Zarka, our favorite monsterologist!

The colossal geometric monuments found at Giza and elsewhere in Egypt are some of Earth’s most impressive constructions. Pyramids are truly wonders of the ancient and modern world. But when the pyramids were built, the ancient Egyptians hadn’t invented the wheel, developed bronze tools, or discovered pi. How were they able to stack two million stone blocks, each weighing more than two tons, into precise geometric alignments that would survive more than 4,000 years and capture the imaginations of explorers throughout history? They did it the same way we always have: by trial and error. The true history of the pyramids is one of experimentation and science, not magic… or aliens. ----------- REFERENCES: Lehner, M. (1997).

    The History of Money (From Barter To Bitcoin)

We all use it. But is it real? I mean, you can touch a coin or bill, but who decided that’s worth anything? And what about all those 1’s and 0’s getting swapped and traded by computers thousands of times per second? How are those worth anything? We trace the history of money, from physical barter to bitcoin, and discover that money isn’t just a lie we all agree to share, it’s been built on the back of technology and invention for millennia.
