Crash Course A&P continues the journey through sensory systems with a look at how your sense of hearing works. We follow sounds as they work there way into the ear where they are registered and transformed into action potentials. This mechanism not only helps you hear but also helps maintain your equilibrium.

In which John Green explores F. Scott Fitzgerald's novel of the Jazz Age, The Great Gatsby. John introduces you to Nick Carraway, Jay Gatsby, Daisy and Tom Buchanan, and the other characters in the novel, and tries to look beyond the surface story to figure out what this thing is ABOUT. Set in the 1920's against a conflicted backdrop of prohibition and excess, The Great Gatsby takes a close look at the American Dream as it existed in Fitzgerald's time. It turns out, it had a lot to do with money and status, and it still does today. John will cover the rich symbolism of the novel, from the distant green light to the pale gold of wealth and decay. Also, Paris Hilton drops by.

Vision behind the painting:
I wanted the main figure to represent strength and independence, and the abstraction surrounding the figure to create a free boundless environment, an imaginary world of some kind. I believe this blend of realism and abstraction can really produce something unique.
I decided to use soothing but as the same time expressive colors and their combinations to support the feelings I want this painting to evoke. Such as a feeling of serenity, strength, awareness.. and certainly a feeling of freedom.


Materials used:
• Oil paints "Nevskaya palitra"
• Frosted acrylic panel

Ratites have spread to Africa, Australia, New Zealand, and South America. And there are fossils of Ratites in Europe, Asia, and North America too. That’s a lot of ground to cover for birds that can’t fly. So how did Ratites end up all over the world?

Experts are still arguing over whether Archaeopteryx was a true bird, or a paravian dinosaur, or some other kind of dino. But regardless of what side you’re on, how did this fascinating, bird-like animal relate to today’s birds? It turns out its teeth were a clue that this story goes all the way back to what we now call the non-avian dinosaurs.

This week, we're continuing our discussion of heroes by talking about Gilgamesh, star of one of the earliest written hero stories, The Epic of Gilgamesh. Gilgamesh was a terrible ancient king who left his kingdom seeking adventure, and eventually on the prowl for immortality. Along the way, he checks pretty much all the boxes on the checklist of Joseph Campbell's Hero's Journey.

In which John Green ACTUALLY teaches about the Civil War. In part one of our two part look at the US Civil War, John looks into the causes of the war, and the motivations of the individuals who went to war. The overarching causes and the individual motivations were not always the same, you see. John also looks into why the North won, and whether that outcome was inevitable. The North's industrial and population advantages are examined, as are the problems of the Confederacy, including its need to build a nation at the same time it was fighting a war. As usual, John doesn't get much into the actual battle by battle breakdown. He does talk a little about the overarching strategy that won the war, and Grant's plan to just overwhelm the South with numbers. Grant took a lot of losses in the latter days of the war, but in the end, it did lead to the surrender of the South. If you want to learn more about the Civil War, we recommend these books:
Battle Cry of Freedom by James McPherson
The Civil War by Shelby Foote

Massive stars fuse heavier elements in their cores than lower mass stars. This leads to the creation of heavier elements up to iron. Iron robs critical energy from the core, causing it to collapse. The shock wave, together with a huge swarm of neutrinos, blast through the star’s outer layers, causing it to explode. The resulting supernova creates even more heavy elements, scattering them through space. Also, happily, we’re in no danger from a nearby supernova.
