Physical Science for Kids is the fun way to learn important facts about physical science and get ready for tests. Take a fascinating journey to the Super Science Station to learn about light and energy.

Using real world demonstrations and colorful graphics, Real World Science: Light teaches students the different properties of light, pertinent definitions and how light travels. Students will learn how different mediums can affect light,...

MUMBAI, INDIA - NOVEMBER 12: CONJOINED twin boys are thriving one year after separation surgery. Twins Prince and Love were born joint at the stomach, and a shared liver, urinary bladder, intestines and fused pelvic bones. But in...

In this video Paul Andersen explains how light can be absorbed, reflected, or transmitted as it moves from one medium to another. The reflection of different wavelengths creates the perceived color of an object. Absorbed light is...

In this video Paul Andersen explains how light can be treated as both a particle and a wave. Physicists use scale to determine which model to use when studying light. When the wavelength of light is equivalent to the size of the object...

In this video Paul Andersen explains how light can be refracted, or bent, as it moves from one medium to another. The amount of refraction is determined by the angle of incidence and the index of refraction. Snell's Law can be used to...

Today we begin our discussion of computer graphics. So we ended last episode with the proliferation of command line (or text) interfaces, which sometimes used screens, but typically electronic typewriters or teletypes onto paper. But by...

In this video, I show you:<br/>
1) How to search UniProt for a protein of interest given its na<br/&<br/>gt;me or code.
AND
2) How to access its XM numbe<br/>r and gene sequence from UniProt.

Companies are counting on their future leaders to manage with more speed, flexibility and trust than ever before. But how can middle managers climb the corporate ladder while also challenging the way things have always been done?...

Across sub-Saharan Africa, small farmers are the bedrock of national and regional economies—unless the weather proves unpredictable and their crops fail. The solution is insurance, at a vast, continental scale, and at a very low,...

When we look at the sky, we have a flat, two-dimensional view. So how do astronomers figure the distances of stars and galaxies from Earth? Yuan-Sen Ting shows us how trigonometric parallaxes, standard candles and more help us determine...

The other day I got bored and noticed this weird thing happened when I held my finger up to my eye, so I had to science it and figure it out! Let me know if you try these light-bending experiments too, especially that last one that I...

In order to see the faint light from objects in deepest space, astronomers go to the darkest places on the planet. In order to listen to their quite radio signals, they head as far from any radio-noisy humans as possible. But there’s...

Sunbeams shooting down through the clouds make for some great photographs, but what's the science behind these beautiful rays of light?

The way light behaves can seem very counter intuitive, and many physicists would agree with that, but once you figure out light waves it all starts to make more sense! In this episode of Crash Course Physics, Shini shows us how we know...

Scientists have created beams of light that are slower than a car! Not only that, but with the literal flick of a switch, they can freeze that beam of light in place!

We've all had the experience: you're walking across a soft carpet, you reach for the doorknob and - ZAP. But what causes this trademark jolt of static electricity? Anuradha Bhagwat sheds light on the phenomenon by examining the nature of...

Can we accurately describe light as exclusively a wave or just a particle? Are the two mutually exclusive? In this third part of his series on light and color, Colm Kelleher discusses wave-particle duality and its relationship to how we...

Tennis legend Billie Jean King isn't just a pioneer of women's tennis -- she's a pioneer for women getting paid. In this freewheeling conversation, she talks about identity, the role of sports in social justice and the famous Battle of...

Light travels through space as fast as anything in the universe possibly can, but before scientists could figure out light’s speed, they had to figure out whether that speed was even finite.

Having the ability to dim your lights seems like a pretty simple thing, but modern dimmer switches work in a surprisingly cool way!

Each kind of light has a unique wavelength, but human eyes can only perceive a tiny slice of the full spectrum -- the very narrow range from red to violet. Microwaves, radio waves, x-rays and more are hiding, invisible, just beyond our...

Ed Boyden shows how, by inserting genes for light-sensitive proteins into brain cells, he can selectively activate or de-activate specific neurons with fiber-optic implants. With this unprecedented level of control, he's managed to cure...

When ultraviolet sunlight hits our skin, it affects each of us differently. Depending on skin color, it'll take only minutes of exposure to turn one person beetroot-pink, while another requires hours to experience the slightest change....
