It will teach about rhythm, the pattern of stressed and unstressed syllables in a line, and meter, the number of feet in a line. Focuses will be on specific vocabulary (iambic hexameter, trochaic pentameter, anapest, dactyls, spondees etc.) and the practical application of differentiating between stressed and unstressed syllables, including feminine and masculine endings.

Everyone loves Harry Potter, but are you aware of the extensive Latin roots and ancient mythology behind the favorite kids books? J.K. Rowling got her degree in Classics, and this is evident in her famous series. This course will discuss the many hidden shout-outs to Classical times, including spells that come from Latin roots, characters' names that evoke mythical meanings, names of places that have ancient connotations, and even the Hogwarts official motto!

Tsar Peter the Great is known for bringing "backwards Russia" to the European Stage. However, He also tortured and killed a ton of people including his son. But he also founded St. Petersburg, a city described to be the "Venice of the North". Except he did that by building the city upon the bones of peasants. But he also highhandedly created a Russian Navy and significantly increased Russia's power in Europe. But he also got notoriously drunk at diplomatic parties and damaged a lot of property.

Who exactly is this guy? Does he matter at all? Who even knows?

Come learn and discuss the life and works of Peter the Great.

Learn about how books looked and who read them before they went digital - that is, a long time before they went digital.

Overview of a variety of computer science algorithms and their uses.

Have you ever wondered how your information is protected? How President Obama might send Putin a message he doesn't want other world leaders to be able to see? Have you ever wondered how math is used in the real world? By surveying historic and modern cryptosystems, this course will provide students with a broad knowledge base for how information is protected.

Topics include: Caesar Cipher, Vigenere Cipher, Public Key systems, RSA, Secret Sharing, and additional topics as time permits.


Prerequisites
Algebra I or Algebra II is needed. Students need to be comfortable with symbol manipulation. Calculus would be helpful but not required. Little to no calculus will be used, but that level of mathematical maturity will be beneficial. This course will have some very difficult parts, other very easy parts. Students with different mathematical backgrounds will be able to understand more or less of the course.

One cool thing about numbers is that they just keep going. For any number you give me, I can give you one that's bigger by simply adding one. But if I asked you to name a big number (none of that infinity garbage), you might say something like "The number of hairs on my head" or "the number of grains of sand in the Sahara". While these numbers are big to us, they are pretty small in a mathematical sense. I want to tell you about TRULY big numbers. Incomprehensibly big numbers. Numbers so big that even computers can't deal with them. This course will focus on computer science, computation theory, the need for mathematical rigor, and number's so large that if you imagined them as a continuous string of digits your head would literally collapse into a black hole killing us all. That last part's not a joke. I'll prove it to you. We'll talk about infinity at the end if time permits.

This course in psychopharmocology will discuss what various recreational and prescription drugs do to the human brain and their effects on the body and behaviors. We will also discuss the science of addiction and its effect on the brain homeostasis.

If you love brains, register for this class! Scientists originally thought that the brain's neural pathways were originally hardwired, much like a machine, and therefore assumed that brain damage in patients was permanent. But with new scientific breakthroughs, researchers have come to realize how incredibly plastic, or moldable, the brain actually is! The brain can, in essence, fix itself! This course will explore this theory that the brain can change itself with the experiences and injuries it faces. If you find brains even remotely interesting, take this class!

Some consider the heart integral to what they do in life. There's no denying it: the heart pops up everywhere, be it in pop culture, engineering, and, of course, the world of medicine.

This course will briefly go over the anatomy of the heart and how the heart works. Then, we will discuss some common complications and current methods to tackle these.


Prerequisites
A heart for fun facts

In this course, we will take a look at the basics of modern neuroscience research in the twenty first century. The connectome is quickly becoming one of the hottest topics for brain scientists. Connectomics enables researchers to map a brain image to a graph, which opens the door to highly simplified analysis of brain functionality. In this course, we will investigate a particular technique for breaking a functional magnetic resonance image (fMRI) into a simple graphical representation. Course topics will include an introduction to matrices, basic statistical techniques for modern day neuroscience, image analysis techniques, and a simplified pipeline for converting a brain image to a connectome. If time permits, we will look at the outlook of connectomic research in the near future, and what is being done here at Hopkins to study connectomes.

If you check out the images, by the end of this course you will have a solid understanding of how we can go from raw brain data to the figures pictured. These figures and their mathematical representations form the basis of modern connectomic research.

Course topics: matrices, network theory, correlation, fMRI basics, timeseries extraction, timeseries analysis, processing


Prerequisites
most topics relevant will be introduced at an easily understandable level, but a basic understanding of high school math will be helpful.
