What separates struggling artists from successful ones? Looking to creative geniuses like Mozart, Edison and Monet, video creator Jon Youshaei explains why aiming to be prolific — despite flops and failures along the way — is the key to...

Conservation laws are among the most important tools in physics. They feel as fundamental as you can get. And yet they're wrong - or at least they're only right sometimes. These laws are consequences of a much deeper, more fundamental...

In this video Paul Andersen explains how scalar fields can be used to show the distribution of scalar quantities. The most important scalar fields in AP Physics 2 deal with electric potential. Scalar addition can be used to combine...

Energy is the most powerful and useful concept in all of physics, but what exactly is it?

In this video Paul Andersen shows conceptual thinking in a mini-lesson on orders of magnitude.

Scale models - a representation that has been reduced or enlarged to a specific
scale
Orders of magnitude - is an approximation...

Mathematician Kelsey Houston-Edwards explains exactly what singularities are and how they exist right under our noses.

Mr. Andersen demonstrates the azide-winkler method of dissolved oxygen analysis.

We breathe constantly, but have you ever thought about how breathing works? Discover the ins and outs of one of our most basic living functions-- from the science of respiration to how to control your breaths.

In this video Paul Andersen shows conceptual thinking in a mini-lesson on physical quantities.

You've found Leonardo da Vinci's secret vault, secured by a series of combination locks. Fortunately, your treasure map has three codes: 1210, 3211000, and. . . hmm. The last one appears to be missing. Can you figure out the last number...

Mr. Andersen explains the differences between scalar and vectors quantities. He also uses a demonstration to show the importance of vectors and vector addition.

So, during times of inflation or deflation, why doesn't the government just set prices? It sounds reasonable, but price ceilings or floors just don't work. Adriene and Jacob explain why. Subsidies, however, are a little different, and...

If being alive on Earth were a contest, humans would win it hands down. We're like the Michael Phelps of being alive, but with 250,000 times more gold medals. Today Hank is here to tell us the specifics of why and how human population...

Mr. Andersen shows you how to use the factor label method to solve complex conversions.

In this video Paul Andersen explains the importance of scale in science and engineering. The Universe varies in size along three scales: size, timespan, and energy. Many phenomenon are too small and fast, or two large and slow to...

Physicists, air traffic controllers, and video game creators all have at least one thing in common: vectors. But what exactly are they, and why do they matter? David Huynh explains how vectors are a prime example of the elegance, beauty,...

In this short math video we will learn how to use the Zero Product Property to find the zeroes of a quadratic function in factored form. We will understand that the Zero Product Property states that any quantity a multiplied by a...

In this math video we will find unit rate using a table. We will be given a relationship where one quantity is a fraction. We will set up and use a table to find the unit rate. We will find the reciprocal and multiply the fractional...

In this math video we will write and simplify a complex fraction to find unit rate. We are given a relationship and asked to find the unit rate. We will write the relationship as a ratio in fraction form. Since one of the quantities...

In this video we will use a double bar diagram to model how to find unit rate with two fractional quantities. We will interpret the information given. We will understand that unit rate is a rate where the second quantity is 1. I will...

In this high school algebra math video we will be interpreting an exponential model or a real world problem.
