In this video Paul Andersen explains how light can be absorbed, reflected, or transmitted as it moves from one medium to another. The reflection of different wavelengths creates the perceived color of an object. Absorbed light is...

In this video Paul Andersen explains how a net torque acting on an object will create rotational motion. This motion can be described by the angular displacement, angular velocity, and angular acceleration. The linear velocity can be...

In this episode of Crash Course Physics, Megneto helps Shini explain what induction is, how it works, and why magnetism is so seemingly complicated.

The useful glare-blocking properties of polarized sunglasses are well-known to just about anyone who goes outside. What isn't so well-known is how they reduce glare in the first place. That answer is deceptively complicated!

Some plants have very unique ways to disperse their seeds. Olivia introduces 5 of the most bizarre seeds in the world!

In this video Paul Andersen explains how light that is perfectly reflected creates specular reflection. The angle of the incident ray is equal to the angle of the reflected ray. Specular reflection is also known as mirror-like...

People have been exploring the oceans since prehistoric times, way before they had GPS to help them figure out where they were. Here are 6 ingenious ways our ancestors navigated the oceans.

In this video Paul Andersen explains how light can be refracted, or bent, as it moves from one medium to another. The amount of refraction is determined by the angle of incidence and the index of refraction. Snell's Law can be used to...

Take a look... A VERY special guest, LeVar Burton, explains how Double Rainbows are formed.

SciShow explains how three important ingredients -- sunlight, water, and you -- interact to create the illusion of a rainbow. The colorful details are inside!

Ever wonder why the earth has different seasons? Michael Aranda will explain in this episode of SciShow Quick Questions.

In this video Paul Andersen explains how electromagnetic induction occurs when the magnetic flux of an object changes. The magnetic flux is product of the surface area perpendicular to the magnetic field and the magnetic field strength....

A bit of the history behind how we came to use the symbol "pi" to represent what it does today, and how Euler used it to refer to several different circle constants.

After a friend of mine got a tattoo with a representation of the cosecant function, it got me thinking about how there's another sense in which this function is a tattoo on math, so to speak.

In this episode of Crash Course Astronomy, Phil takes you through the cause and name of the Moon's phases.

Paul Riario dives into the all-new Suhr Oso — a short-scale powerhouse that blends vintage vibe with modern finesse. Designed by John Suhr, the Oso reimagines a classic T with blind fret ends, compact spacing, and unmatched playability....

In this video we are going over how use the height of an oblique triangle to determine if you have 1 2 or no triangles

In this video we are going to explore a great question that many students struggle with in solving trigonometric equations.

This Student asked me to graph the radian in standard form so I decided to make a video about it how I like to approach it.

In this video I am going to work through how to evaluate a basic trig function using the unit circle and one more difficult

In this video we are going to work on how to determine the quadrant that the terminal side of an angle lies in.

In this video we are going to cover the trap that is the ambiguous case. If you struggle with understanding 1,2 or no triangles and how to find the missing parts then this is the right video for you.

Not all problems should be done in your head, but sometimes it is advised to do math in your head. Here are my top problems I want my students to be able to do.

In this video, I'll walk you through graphing cosecant functions by first focusing on the reciprocal sine graph. We'll explore the process for y=csc(2x) by understanding its relationship to y=sin(2x), covering key elements like amplitude...
