You’re probably familiar with the basics of magnets already: They have a north pole and a south pole. Two of the same pole will repel each other, while opposites attract. Only certain materials, especially those that contain iron, can be magnets. And there’s a magnetic field around Earth, which is why you can use a compass to figure out which way is north. In this episode of Crash Course Physics, Shini takes us into the world of magnetism!

In the early 1800s, Michael Faraday showed us how a changing magnetic field induces an electromotive force, or emf, resulting in an electric current. He also found that electric fields sometimes act like magnetic fields, and developed equations to calculate the forces exerted by both. In the mid-1800s, Scottish physicist James Maxwell thought something interesting was going on there, too. So he decided to assemble a set of equations that held true for all electromagnetic interactions. In this episode of Crash Course Physics, Shini talks to us about Maxwell's Equations and how important they are to our understanding of Physics.

In this, THE FIRST EPISODE of Crash Course Physics, your host Dr. Shini Somara introduces us to the ideas of motion in a straight line. She talks about displacement, acceleration, time, velocity, and the definition of acceleration. Also, how does a physicist discuss speed as opposed to a police officer? And did you deserve that ticket? You can figure it all out with the help of Physics!

I'm sure you've all heard about Isaac Newton and that apple that fell on his head and how that was a huge deal to our understanding of gravity. Well... let's talk about that. In this episode of Crash Course Physics, Shini sits down to talk about the realities of the apple story and how Newtonian Gravity is more than a little important.

It's time for our second to final Physics episode. So, let's talk about Einstein and nuclear physics. What does E=MC2 actually mean? Why is it so useful to us as physicists and humans? In this episode of Crash Course Physics, Shini sits down to go over the basics of it all.

How do lenses work? How do they form images? Well, in order to understand how optics work, we have to understand the physics of light. In this episode of Crash Course Physics, Shini talks to us about optical instruments and how they make magnification possible.

Have you ever wondered why we wear clothes? I mean, beyond the obvious. Why does wearing a jacket in the cold keep you warmer? What is happening to all the heat inside your body? In this episode of Crash Course Physics, Shini talks about the physics of heat!

Music plays a big part in many of our lives. Whether you just like to listen or you enjoy playing an instrument, music is powerful. So what is music? How does it work? What are the physics of music? In this episode of Crash Course Physics, Shini talks to us about how music functions in terms of waves and how these waves interact with our ears.

What is light? That is something that has plagued scientists for centuries. It behaves like a wave... and a particle... what? Is it both? In this episode of Crash Course Physics, Shini introduces the idea of quantum mechanics and how it helps us understand light. Also, there's this thing called the ULTRAVIOLET CATASTROPHE!

e=mc2... it's a big deal, right? But why? And what about this grumpy cat in a box and probability? In this episode of Crash Course Physics, Shini attempts to explain a little more on the topic of quantum mechanics.

Did you know that at a certain point on a moving wheel... there's no motion? I mean, kinda... it's all relative, right? Prepare to have your mind blown in this episode of Crash Course Physics where Shini delves into the world of rotational motion!

Bridges... bridges, bridges, bridges. We talk a lot about bridges in physics. Why? Because there is A LOT of practical physics that can be learned from the planning and construction of them. In this episode of Crash Course Physics, Shini talks to us about a particular mistake made in engineering the Millennium Bridge which allows us to talk about simple harmonic motion.

We learn a lot about our surroundings thanks to sound. But... what is it exactly? Sound, that is. What is sound? And how does it travel? And what is this doppler effect that we've heard so much about? In this episode of Crash Course Physics, Shini goes over some of the basics (and some of the not-so-basics) of the Physics of Sound.

So we've all heard of relativity, right? But... what is relativity? And how does it relate to light? And motion? In this episode of Crash Course Physics, Shini talks to us about perspective, observation, and how relativity is REALLY weird!

Light is everywhere … but it’s not as predictable as you might think. It’s a wave that travels in straight lines, yet it also reflects off of surfaces, refracts through various materials, and generally changes direction all the time! We’ve learned how to bend light to our will, with lenses and mirrors, but it’s time to take a step back and ask what we can LEARN from light.

The Physics we're talking about today has saved your life! Whenever you walk across a bridge or lean on a building, Statics are at work. Statics is the study of objects when they're NOT accelerating. In this episode of Crash Course Physics, Shini talks to us about stretching, compressing, and springing as they relate to statics! Also... Game of Thrones.

Bridges. Bridges don't deal well with temperature changes. In order to combat this, engineers have come up with some workarounds that allow bridges to flex as they expand or contract. In this episode of Crash Course Physics, Shini talks to us about temperature and the ideal gas law. Also, we figure out how much air is in your car.

Have you ever heard of a perpetual motion machine? More to the point, have you ever heard of why perpetual motion machines are impossible? One of the reasons is because of the first law of thermodynamics! In this episode of Crash Course Physics, Shini talks to us about thermodynamics and entropy. Also, we learn about isovolumetric, isobaric, isothermal, and adiabatic processes. It'll all make sense in a minute!

What is torque? This is one of those things that you may have heard about in passing but never really understood. In this episode of Crash Course Physics, Shini sits down with us to discuss what torque is, how it works, why it works, and what it all has to do with this thing called "moment of inertia."

Waves are cool. The more we learn about waves, the more we learn about a lot of things in physics. Everything from earthquakes to music! Ropes can tell us a lot about how traveling waves work so, in this episode of Crash Course Physics, Shini uses ropes to talk about how waves carry energy and how different kinds of waves transmit energy differently.
