Human reproduction is complicated and important, and it's going to take a four-part series for us to cover it. Today, we're kicking that off with the female reproductive system, starting with how sex hormones affect oogenesis and ovulation, continuing through how the ovarian and menstrual cycles mature and release oocytes, and creating a comfy uterine environment for a fertilized egg.

Sex is complicated for different reasons in different cultures. But, it's the entire purpose of life, so there's no reason to blush. In this episode of Crash Course Psychology, Hank talks about Kinsey, Masters and Johnson, Sexuality, Gender Identity, and Hormones, and even looks into the idea of why we have sex. There's a lot to go through here.

The thing about European History is that it tends to leak out of Europe. Europeans haven't been great at staying put in Europe. As human beings do, the people of Europe were very busy traveling around to trade, to spread religion, and in a lot of cases to try and conquer other people. In the 15th and 16th centuries, Europeans developed a bunch of tools and techniques that would allow them to travel around the world, in numbers and force heretofore unseen on the planet. And a lot of the results weren't great for the people who already lived in the places Europeans were "visiting."

Today, we're going to talk about one of the earliest animal senses, one that every life form we've ever found seems to have -- chemosensation -- or our sense of taste and smell. We'll discuss how animals use these senses to explore their environment and communicate, and how that pair of nostrils of yours is an example of convergent evolution. Also, before we wrap up our discussion of animal senses we're going to talk about a couple so specialized that seem straight from the pages of comic books -- the ability to sense electric and magnetic fields!

James Cameron rocketed onto the action film scene with 1984's "The Terminator" and followed that up with a highly anticipated sequel to the 1979 film, "Alien." His film, "Aliens," would go on to not only be a financial success, but a critical one and has become a staple of action, science fiction, and effects filmmaking.

But, "Aliens" also rewards a deeper look through a critical lens in both some positive and not so positive ways.

***Alien and Aliens are the property of 20th Century Fox.

Check out all 15 films we'll be talking about below!!!

***Film Selection***
Citizen Kane
Aliens
Where Are My Children?

In the Mood For Love
Do the Right Thing

Today we’re going to talk about recommender systems which form the backbone of so much of the content we see online from video recommendations on YouTube and Netflix to ads we see on Facebook, Twitter, and well, everywhere else. We’ll talk about their types of systems - content-based, social, and personalized recommendations - and take a closer look at what they're good at, but also why they often fail.
