The latest installment of MinutePhysics tackles the enduring question of why the sky appears blue, and the less common (albeit related question) of why the sun appears yellow.
If stars themselves are giant balls of gas and appear as dots in the night sky, why is it so common to draw them with pointed arms? Minute Physics explains how the light from stars interacts with our eyes to create that "star-shaped" image.
If you've ever tried balancing something as short and skinny as a pencil on your fingertip, you know it isn't easy. Why is that? How is it possible to create a free-standing rock sculpture like this one, when it's all but impossible to balance a stinking pencil for more than a couple seconds?
The ocean is full of plastic. Not big pieces of plastic, as you've probably heard, but tiny bits of plastic. Microplastic. Plastic that hasn't decomposed, but broken down into small pieces that are incredibly durable. We've found this stuff throughout the world's oceans, at every depth. What kind of environmental…
Ever wonder why squinting helps you focus when you've misplaced your glasses? Or why things appear clearer when viewed through a small hole? Here's the answer in video form.
Winter makes for longer nights and shorter days. It also boasts the year's greatest lunar displays – but there's more to this fact than an increase in daily hours of darkness.
Henry Reich of Minute Physics may have just set a world record for providing the quickest explanation to that infamously inexplicable phenomenon: Earth's tides.
It's a match made in YouTube Science Heaven: In the latest episode of Minute Physics, Henry Reich teams up with the folks at Veritasium to address one of the Internet's favorite scientific conundrums: MAGNETS.
Between 2006 and 2012, 127 Americans died from being struck by lightning. Here's how you can avoid joining their ranks.
Here's an idea! Let's get reeaaaal pedantic about what it means for an object to be truly "immovable" (i.e. "un-accelerateable") and a force to actually be unstoppable (spoiler: all forces are unstoppable) and use the thought experiment to answer one of the oldest, most ancient questions to ever come up ever. Turns…
Here to give us the down and dirty on space excreta (because let's face it, you were always curious) is Minute Physics' Henry Reich and Smarter Every Day's Destin. It's a match made in YouTube science-explainer heaven. With poop. And spacecraft-trajectory-altering pee. In spaaaace.
Henry Reich — creator, illustrator and narrator of Minute Physics — has a message for the President. America's educational standards for physics, he argues, provide a surprisingly dated and incomplete introduction to the world of physics. A lot has happened in the field since 1865; shouldn't some basic knowledge of…
This is the story of how quantum mechanics — that physical science of the very, very small — came to be. It's a fascinating tale involving Max Planck, Albert Einstein, cookies and fussy light.
Minute Physics' Henry Reich takes a break from physics to drop some maths knowledge. Using some basic tenets of set theory, Reich explains how we know that one infinity can be bigger than another.
We all know that time has direction, because we've all experienced it; you will never again be as young, for example, as you are at this very second. Or this second. Or this second. The directionality of time prohibits it.
Sure, our surroundings certainly appear to exist in three dimensions, but any good Cartesian will tell you that the appearance of a material object alone is insufficient evidence of its true nature. So how do we go about proving that we aren't, in fact, deluded inhabitants of Abott's two-dimensional Flatland, or…
