NASA scientists are said to have invented a lot of household items over the decades. Some, like Velcro, or Tang, or the first cordless power tools, are misattributions. But other claims are totally legit. And you probably own at least...

Space is a dangerous place. One of the many dangers comes in the form of radiation. On Earth, sunscreen helps shield our bodies. But astronauts on the ISS, or eventually on the Moon/Mars/etc., will have to be rocking some suped-up sunblock.

Ovens are great for baking, cooking, and.... discovering quantum mechanics? In this fascinating episode of SciShow, Hank takes you through the science of quantum mechanics, and how ovens played a big part in their discovery.

Can the radiation emitted by electronic devices affect your body and make you feel terrible?

You've probably heard that carbon dioxide is warming the Earth. But how exactly is it doing it? Lieven Scheire uses a rainbow, a light bulb and a bit of quantum physics to describe the science behind global warming.

In this video Paul Andersen explains how humans use information technology and instrumentation to better understand their surrounds. Technologies (including X-rays, computers, and phones) use electromagnetic waves to improve the lives...

When we hear the word radiation, it's tempting to picture huge explosions and frightening mutations. But that's not the full story - radiation also applies to rainbows and a doctor examining an X-ray. So what is it, really, and how much...

Join Hank Green as he explains why blacklights make some things glow!

Much like a cell membrane, our atmosphere forms a protective boundary between outer space and the biosphere that allows for all life to exist on Earth’s surface. Today, we’re going to talk about its composition and layers (the...

Many people avoid using microwave ovens, fearing how it changes the molecular structure of your food, but studies have some evidence that may surprise you.

In this video Paul Andersen explains how heating is the transfer of energy (heat) from a warmer object to a cooler object. Heat can be transferred through conduction, convection and radiation. At the microscopic level conduction...

You might think that quantum physics was discovered because of some super complicated electron behavior or something, but it was actually invented to explain ovens.

Unlocking the mysteries of ancient ceramics is a bit complicated. Radiometric dating tells us the age of the clay, but when was it first shaped by a human? We can find out by blasting it with heat again!

In this video Paul Andersen describes some of the properties of electromagnetic radiation. The electromagnetic spectrum varies by wavelength from radio waves to gamma rays. We only see a portion of the spectrum known as visible light. ...

In this video Paul Andersen details the characteristics of electromagnetic waves. Electromagnetic waves are transverse waves that can move through both mediums and vacuums. The electric and magnetic fields oscillate perpendicular to...

In this video Paul Andersen details the waves in electromagnetic radiation. There is an inverse relation between the wavelength and frequency of electromagnetic waves. Electromagnetic radiation includes gamma rays, x-rays, infrared...

In this video Paul Andersen describes the major parts of an atom and explains how the Bohr Model more accurately represents the location of electrons around the nucleus. Niels Bohr refined the Rutherford model to account for spectra.

Paul Andersen explains how natural selection is a major mechanism in evolution. The video begins with a discussion of Charles Darwin and the details of natural selection. The data of the peppered moth during the industrial revolution...

In this video Paul Andersen explains how heat is the movement of energy from an object with a higher temperature to an object with lower temperature. Heat transfer can occur through conduction, convection, and radiation.

Not only do they describe every electrical and magnetic phenomenon, but hidden within these equations is a fundamental truth about the nature of light, and why it is the ultimate speed of the universe. We...

Summary:

The information that we know about the universe comes almost exclusively from the analysis of electromagnetic radiation. But there is only so much this light can reveal because there is an inherent...

Max Planck's theory was  proposed by Max Planck in 1900 revolutionized the field of physics by introducing quantum mechanics and fundamentally reshaping our comprehension of the subject. Planck conducted research on black body...

In 1913, Niels Bohr proposed an atomic model that dramatically altered our comprehension of atomic structure by establishing a novel framework for describing the arrangement and behaviour of electrons within an atom....

Black body radiation is a fundamental topic in physics that has significantly influenced our understanding of quantum mechanics. A black body is an idealized physical object that absorbs all electromagnetic radiation, regardless of...
