This video is about how Albert Einstein made a mistake when applying the Field Equations of General Relativity to cosmology (in particular, to a static, constant density universe), and solved the...

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!

Dive into fluid dynamics with this step-by-step walkthrough of a challenging Bernoulli's equation problem. Learn how to calculate the radius of a pipe using ideal fluid flow, volumetric flow rate, and pressure differences. Whether you're...

For years, astronomers have been unable to find up to half of the baryonic matter in the universe. We may just have solved this problem.

Learn how the speed of an ideal fluid changes when it flows through a pipe with varying cross-sectional areas. In this fun and engaging video, we apply the continuity equation for volumetric flow rate and solve a problem step-by-step....

This video shows the process for solving the problem presented in IGCSE A June 2018 paper 2HR Q2, which involves force. By using the formula for pressure and the given dimensions of the rectangle, we will work through the steps to...

This video shows the process for solving the problem presented in IGCSE A June 2018 paper 1HR Q11, which involves unit conversion. In this video, we will start by reviewing the basic units of length and time and their relationship. Then,...

Stories of discovery and invention often begin with a problem that needs solving. Summoned by the king to investigate a suspicious goldsmith, the early Greek mathematician Archimedes stumbles on the principle that would make him famous.

Cosmic inflation is a theory that was proposed in the 1980s by cosmologist Alan Guth to answer some of the most fundamental questions of the origins of our universe. It also solved the Horizon Problem and the Flatness Problem.

Here, we perform a sample calculation for heat capacity in which we solve for heat (q) using q=smΔT.<br/>

Join us as we investigate a classic question: what happens to the water level in a glass when a chunk of ice melts? Learn about buoyant force, density, and volume displacement, and witness the principles of physics come to life before...

In this video, I work a second example problem using the principle of corresponding states.<b<br/>r/>

-Find the temperature and pressure at which a gas b<br/>ehaves as another gas.

The Centroid of an area is the same as the center of mass for objects which have constant thickness and constant density. A general approach to solving centroid problems is to:

1) define an
axis
2) Find equations o
f...

It’s one of the biggest mysteries in science. It makes up the majority of the universe. What is dark energy? What is dark energy made of? What is quintessence? Is Dark energy the cosmological constant?...

Einstein Field equations explained intuitively and visually: Isaac Newton changed our paradigm by connecting earthly gravity, with the movement of heavenly bodies. He formulated an equation that is...

Traffic is one of the biggest problems plaguing cities today. Idling cars cause increased emissions, more traffic means more accidents, and it is, of course, annoying. Meet traffic scientist, Dr. Alex Bayen who is working to solve...
