Get to know plasma, the most common, but probably least understood, phase of matter in the universe!

Researchers have published a new method of guiding lightning strikes using a laser. And another team of researchers developed a new test that uses DNA as bait for respiratory viruses like COVID-19.

In order to have a meaningful conversation about the dangers of radiation exposure, it’s important to be clear about just how much radiation we are dealing with. Unfortunately, the units we use are kind of a mess… but SciShow is here...

Hank explains the whole story about radiation - the good, the extremely helpful, and the bad.

Get to know plasma, the most common, but probably least understood, phase of matter in the universe!

A bisected grape in the microwave makes plasma. But how does it work? A grape is the right size and refractive index to trap microwaves inside it. When you place two (or two halves) close together the fields interact with each other...

One of the most confusing points with acids is the difference between strength and concentration. This video covers exactly what strong vs weak means and explains what the pH scale really represents. This video is suitable for: - Higher...

The video is a lecture on the natures and properties of nuclear radiations. The speaker discusses the three types of ionizing radiation: alpha particles, beta particles, and gamma rays. They explain the ionizing and penetrating abilities...

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

Today, your Passport to Discovery takes you to UCLA's Basic Plasma Science Facility. Come learn how this facility uses a vacuumed sealed tube to create super-heated gas.

An introduction to mass spectrometry.

In this video, the teacher explains the concept of acidity and pH levels. They discuss the differences between strong and weak acids, as well as dilute and concentrated solutions. The teacher also demonstrates how to test the pH of a...
