Imagine an electric vehicle that can get you to work -- or anywhere in a six-mile radius -- quickly, without traffic frustrations or gasoline. Now imagine you can pick it up and carry it with you. Yes, this souped-up skateboard could...

Paul Andersen begins this podcast with a discussion of brain lateralization and gives a brief demonstration of tests that were performed on split-brain individuals. He then discusses the major parts of a neuron and explains how action...

Electronic music is older than you may think. Enter the theremin - a device that turns your body into part of a capacitor, and allows you to play music without even touching an instrument!

In this video Paul Andersen details the action potential in neurons. The resting potential of a neuron (-70mV) is maintained through differences in concentration and permeability of Na, K, and Cl ions. A graded potential is created as...

What do you and a sack of batteries have in common? Today, Hank explains.

Pet trackers, and lots of other electronics, have little cylinders inside them called ferrite beads. If they didn't, they'd probably be picking up the local traffic report instead.

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. ...

Paul Andersen explains how objects interact when touching and at a distance. Electromagnetic forces are very important when objects are touching and fields explain both electromagnetic and gravitational forces. The strong and weak...

You might have heard about animals behaving oddly right before an earthquake hits. But are these reports more than just anecdotes?

In this video Paul Andersen explains how electric permittivity of a material resists the formation of electric fields. Capacitors store energy be preventing the formation of electric fields in dielectric material. The electric...

You’ve probably seen the videos on YouTube turning grapes into fireballs in the microwave. Well, there’s a pretty cool scientific explanation for why a grape is perfect for making plasma.

Thunder is not something you normally associate with a winter storm. However, if the conditions are right, you might experience thundersnow.

Plastic is an incredible substance for the economy -- and the worst substance possible for the environment, says entrepreneur Andrew Forrest. In a conversation meant to spark debate, Forrest and head of TED Chris Anderson discuss an...

Some fish have superpowers! Zebrafish eyes can boost the color and contrast of what they see and baby whale fish are electric.

You probably know about the geomagnetic field that protects the earth from solar storms and radiation. But precision satellites have measured ANOTHER magnetic field coming from Earth, and its signals might hold the key to searching for...

In this video Paul Andersen explains how the nucleon number and charge is conserved in all nuclear reactions and radioactive decay. Fission, fusion, alpha decay, beta decay, and gamma decay all conserve the number of neutrons and...

A more equal world starts with you. Citing a formative moment from her own life, equity advocate Nita Mosby Tyler highlights why showing up and fighting for others who face injustices beyond your own lived experience leads to a fairer,...

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

Jeff Smith spent a year in prison. But what he discovered inside wasn't what he expected -- he saw in his fellow inmates boundless ingenuity and business savvy. He asks: Why don't we tap this entrepreneurial potential to help...

Even though doctors have been using general anesthesia for nearly 200 years, they haven’t really understood the details of how it temporarily shuts down your brain — until now.

In this video Paul Andersen explains how the electric field strength decreases as the square of the radius as you move away from a point charge, or a uniform distribution of charge on a sphere. This is a direct application of Coulomb's...

Ever wonder how your finger can magically control your smartphone screen? We explain in this episode of SciShow.

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...

It might sound like science fiction, but if you press on a crystal of sugar, it will actually generate its own electricity. This simple crystal can act like a tiny power source because sugar happens to be piezoelectric. Ashwini...
