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.

Turn on the captions. You'll like it.

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
• Paint thinner (odorless mineral spirits)
• Medium (stand linseed oil)
• Brushes - round detail brushes in sizes 1, 0 and 00; and synthetic filbert brushes in different sizes.
• Glass palette (homemade)
• Palette knife (from a local art-store)
• Paper towels (or tissues that I use to wipe the brushes)

We all belong to the only group of hominins on the planet today. But we weren’t always alone. 100,000 years ago, Eurasia was home to other hominin species, some of which we know our ancestors met, and spent some quality time with.

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 Craig talks about police searches and seizures. Now, the fourth amendment says that you have the right to be protected against "unreasonable searches and seizures" but what exactly does this mean? Well, it's complicated. The police often need warrants issued with proof of probable cause, but this isn't always the case - such as when you're pulled over for a moving violation. We'll finish up with the limitations of these protections and discuss one group of people in particular that aren't protected equally - students.
