Astrophysics and Cosmology: Crash Course Physics #46

In this episode of Crash Course Physics, Shini sits down to talk about Astrophysics and Cosmology. By using what we've learned this year, we can come to understandings about our universe. Understandings that open ideas to us to help us grasp how our universe works. Join us for this final episode of Crash Course Physics as we head into the final frontier.

AC Circuits: Crash Course Physics #36

We've talked about AC Circuits, but now it's time to delve into the world of AC Circuits (or Alternating Currents). We’ve talked about how they change voltage, which helps transmit electricity over long distances, but there’s so much more to the physics of AC circuitry.

Light Is Waves: Crash Course Physics #39

The way light behaves can seem very counterintuitive, and many physicists would agree with that, but once you figure out light waves it all starts to make more sense! In this episode of Crash Course Physics, Shini shows us how we know that light exists as a wave and why that's really cool!

Nuclear Physics: Crash Course Physics #45

It's time for our second to final Physics episode. So, let's talk 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.

Maxwell's Equations: Crash Course Physics #37

In the mid-1800s, Scottish physicist James Maxwell thought something interesting was going on with electric fields. 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.

Geometric Optics: Crash Course Physics #38

Sunlight, moonlight, torchlight, and flashlight... They all come from different places, but they’re the very same thing: light! It’s what makes it possible for us to see the world around us, so it’s worth a close, hard look. For instance, how does light travel? When you flip that switch in the bathroom to brush your teeth, how does light move from the light bulb, to the mirror, and into your eyes?

Special Relativity: Crash Course Physics #42

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!

Optical Instruments: Crash Course Physics #41

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.

Magnetism: Crash Course Physics #32

Magnets 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!

Ampère's Law: Crash Course Physics #33

Hans Christian Oersted had just discovered the connection between electricity and magnetism. Meanwhile, a French physicist named André-Marie Ampère was experimenting with some wires, trying to learn more about the connection between currents and the magnetic fields they create. Ampère would discover one of the most fundamental laws of electromagnetism: what we now call Ampère’s Law.

Quantum Mechanics - Part 1: Crash Course Physics #43

What is light? That is something that has plagued scientists for centuries. It behaves light 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!

Spectra Interference: Crash Course Physics #40

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.

Capacitors and Kirchhoff: Crash Course Physics #31

What happens when there are MULTIPLE batteries, connected in ‘parallel’? And what happens when we add ‘capacitors’ into the mix, with resistors in our DC circuits? On this, our last go-round inside a DC circuit, we’ll encounter junctions, loops, and capacitors!

Resistors & Batteries: Crash Course Physics #29

Batteries power much of your daily life, so today we're going to talk about how they work. We're also explaining how terminal voltage results from the natural internal resistance of every real battery.

8m 11s

Electric Current: Crash Course Physics #28

Electric current works like a river... kinda... Instead of flowing based on elevation, electric current works a little differently. But it's a good metaphor. In this episode of Crash Course Physics, Shini talks to us about electric current, voltaic cells, and how we get electric charge.

Voltage & Capacitors: Crash Course Physics #27

So, how do those defibrillators you see on TV actually work? Surprise! Physics can explain! Okay buckle up, everyone! Today, Shini has the task of breaking down Electrical Potential Energy, Electric Potential, Voltage, Capacitors, Energy Storage, and Potential Energy... it's a lot!

Fascinating. Entertaining.

Yours.
