In this video Paul Andersen explains how the energy, charge, and momentum in a system is conserved over time.

The idea of conservation might seem like a thing that’s only popped up in the last century or so, but organized efforts to conserve resources that directly benefit humans go back centuries!

Between 2006 and 2016, the number of drug patents granted in the United States doubled -- but not because there was an explosion in invention or innovation. Drug companies have learned how to game the system, accumulating patents not for...

In this video Paul Andersen shows conceptual thinking in a mini-lesson on the conservation of energy. Two examples are included in the video and two additional examples are included in the linked thinking slides. ...

In this video Paul Andersen explains how the charge is conserved in nuclear reactions. When elementary particles are created or destroyed in a reaction the net change in charge will remain constant. Alpha, beta -, and beta+ decay are...

SciShow Psych host Brit Garner joins Hank to talk about wildlife conservation, big data, and Complexly’s new show Nature League, and Jessi stops in with a whole mess of invertebrates.

Today Shini explains the law of conservation, beginning with simple, steady-state systems. We’ll discuss conversion and yield, accumulation, and how generation and consumption can affect how much accumulation there is in a system.

Did you know you have useful tools right at your fingertips? That's right: your fingernails! Jessi and Squeaks learn why fingernails are so important!

Conservationist and TED Fellow Moreangels Mbizah studied the famous Cecil the lion until he was shot by a trophy hunter in 2015. She wonders how things could've gone differently, asking: "What if the community that lived next to Cecil...

Hank wraps up the Crash Course on ecology by taking a look at the growing fields of conservation biology and restoration ecology, which use all the kung fu moves we've learned about in the past eleven weeks and apply them to protecting...

SciShow News takes you to the depths of the Earth, where the world’s most abundant mineral is found, and to the Arabian Sea, where a strange population of whales has been living in isolation for 70,000 years!

Some scientists believe we are in the middle of Earth’s sixth mass extinction: a big, precarious game of Jenga that involves every ecosystem on the planet. In this episode of Crash Course Biology, we’ll see how conservation biology aims...

In this video Paul Andersen explains how the conservation of charge applies to objects in a system. When a charged object induces charge or conducts charge to a neutral object the net total of charge will not change. Grounding allows...

Howcast - Learn about the best time of year to visit Dubai in this Howcast travel video.

SUMMARY

The law of energy conservation may be the most fundamental law in physics. It says that overall energy is always conserved. It can never be created nor destroyed - it can only change form. But this law...

👉 Learn how to find the derivative of an implicit function. The derivative of a function, y = f(x), is the measure of the rate of change of the function, y, with respect to the variable x. The process of finding the derivative of a...

The CEO and chief pilot of JetPack Aviation, David Mayman, talks with WSJ personal technology columnist Joanna Stern about creating the first jetpack.

It presents arguments for conservation of biodiversity including narrowly utilitarian, broadly utilitarian and ethical reasons. It also describes in-situ and ex-situ conservations methods.

Learn the basics about the law of the conservation of mass, when learning about properties of matter. The Law of Conservation of Mass says that in chemical reactions no matter is lost or gained. The law of conservation of mass means that...

Dr. Forrester explains the basic factors influencing the choice to settle in a particular region and the forced resettlement of the Cherokee from their homeland.

On April 16, 1972, Apollo 16 launched to the moon! Apollo 16 was NASA's fifth lunar landing and the penultimate mission of the entire Apollo program. Three NASA astronauts were on board: John Young, the commander, Ken Mattingly, the...
