In this video Paul Andersen explains how the bond length and bond energy are calculated using an energy distance graph. The strength of the bond is determined by the charges in the constituent atoms. As the charge increases the bond...

Researchers have made some unexpected readings of mysterious particles called muons, which may make us reexamine the Standard Model in physics.

In the field of medical prosthetics, things are changing quickly. Learn about mind-controlled limbs, and research that suggests that we may be able to go high-tech with low-cost materials.

The study of electricity goes all the way back to antiquity. But, by the time electricity started to become more well known, a few familiar names started to appear. Edison, Galvani, and a few others really changed the way the world worked.

Mr. Andersen defines the terms energy, work and power. He also uses a simple example to calculate both work and power.

The concepts of work and power help us unlock and understand many of the physical laws that govern our universe. In this Lesson, Peter Bohacek explores the interplay of each concept when applied to two common objects---a lightbulb and a...

As the Earth's surface temperature gradually rises, it has become vital for us to predict the rate of this increase with as much precision as possible. In order to do that, scientists need to understand more about aerosols and clouds....

In economics, a gross domestic product — or GDP — deflator is a factor that is used to compare today's market prices to the market prices from a previous year. Calculating is simple once you know how.

When you make a measurement, it is important to know how accurate it is. Use relative error to express accuracy as a relative quantity.

The switch was closed for a long time before t = 0. Current measured by ammeter is 1 A at t = 0-. At time t = 0, the switch is opened. What is the value of the unknown voltage? What is ammeter’s reading at time t = 0+ s? What is...

What is Growth in a Startup Venture? There's an initial period of slow or no growth while the startup tries to figure out what it's doing. As the startup figures out how to make something lots of people want and how to reach those...

Business activity monitoring is software that aids the monitoring of business activities which are implemented in computer systems.

What's the difference between a CPU and GPU? And what the heck is a TPU, DPU, or QPU? Learn the how computers actually compute things in this quick lesson.
