An Astronomically Correct Rendition Of Twinkle, Twinkle, Little Star

Saturday Morning Breakfast Cereal creator Zach Weinersmith, MinutePhysics' Henry Reich, and illustrator Chris Jones bring us the version of Twinkle, Twinkle, Little Star that every kid should grow up learning. Kids don't have to "wonder what you are." Science explains it all. » 12/23/14 2:40pm 12/23/14 2:40pm

Why Do We Eat Spoiled Food?

Not all spoiled food is created equal. Most everyone has an aversion to rotten foods. After all, they taste awful. But what about the foods we spoil intentionally? What separates rancid meet, for example, from moldy cheese, or bacteria-laden Salami? » 12/21/14 1:00pm 12/21/14 1:00pm

Why Is It So Damn Hard to Balance a Pencil on Your Fingertip?

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? » 8/21/14 2:20pm 8/21/14 2:20pm

The Ocean Is Crowded With Tiny Little Bits Of Plastic

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… » 5/11/14 9:47am 5/11/14 9:47am

Here's why winter has the best full moons

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. » 12/18/13 6:20am 12/18/13 6:20am

Earth's tides, explained in 9.999 seconds

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. » 11/14/13 8:20am 11/14/13 8:20am

When the Universe expands do we expand with it?

If the Universe is expanding (as opposed to, say, getting fat), shouldn't we, our planetary neighborhood, our galaxy, be expanding right along with it? If so, would we even be able to notice? » 8/02/13 6:20am 8/02/13 6:20am

Here's what happens when an unstoppable force meets an immovable object

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… » 1/25/13 12:20pm 1/25/13 12:20pm

Is there poop on the Moon?

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. » 12/14/12 7:00am 12/14/12 7:00am

Some infinities are bigger than other infinities. Here's how we know…

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. » 5/12/12 1:40pm 5/12/12 1:40pm

How Einstein Came Up With Special Relativity

Time dilation. Length contraction. The fact that time moves faster at your face than it does at your feet. These are all experimentally verified consequences of the Special Theory of Relativity, proposed in 1905 by Albert Einstein. But the theory also helped explain one of the most nagging questions of modern… » 3/19/12 8:20am 3/19/12 8:20am

How much milk would you have to vomit in order to levitate?

In X-Men: First Class, Banshee uses ultrasonic screaming like a jet pack to power his flight. In a recent video from special effects whiz Freddie Wong, a character named "Milk Man" gushes gallons of milk from his gullet to achieve a similar effect. » 2/13/12 8:45am 2/13/12 8:45am

How do we know for sure that we live in three dimensions?

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… » 9/06/11 8:00am 9/06/11 8:00am
