The Surprisingly Complex Way That Scientists Measure Sea Level

Most of us have probably never given a second thought as to how sea level is determined. It's basically where the ocean starts, right? Not even close. It turns out there are countless factors that have to be taken into account because the oceans simply aren't at the same level all around the world. » 11/25/13 3:20pm 11/25/13 3:20pm

A Quick (Crazy Quick) Explanation of Negative Temperature

With Minute Physics videos we pretty much expect to have the universe explained to us in . . . a minute. Or maybe a few minutes. But this rundown of temperature and how to achieve "negative temperature" only takes 10 seconds. Impressive. » 11/17/13 9:00pm 11/17/13 9:00pm

How To Improve Your Chances of Surviving a Lightning Strike

It's no secret that finding yourself outside and exposed during a thunderstorm greatly enhances your risk of being struck by lightning.

Where Exactly Did the Big Bang Actually Happen?

When you think of the big bang, that cosmic explosion that jump-started the ever-expanding universe as we know it, it's only natural to imagine it as a single point. One corner of space that just blew up into the galactic being. But where was it? » 8/24/13 10:01am 8/24/13 10:01am

Can Humans Really Feel Hot and Cold?

If you compare the feeling of touching a piece of metal versus a piece of paper, the metal will always seem cooler, even if both objects are actually the same temperature. So what gives? It turns out that what we're really feeling as cold when we touch something is actually an object's increased ability to conduct… » 5/30/13 12:20pm 5/30/13 12:20pm

One of the Basic Math Rules You Learned In School Is Wrong

There are probably a lot of things you learned in school that you don't even remember, but the "order of operations"—also known as PEMDAS—is likely to be one that stuck with you; you'll mess up even simple equations without it. The catch? Well, it's wrong. » 5/18/13 7:30pm 5/18/13 7:30pm

How Parallel Universes Actually Work, Scientifically

Parallel universes are basically the most popular trope in science fiction, because Batman and Spider-Man in alternate universe costumes are awesome, and also human existence is inherently full of awful, soul-crushing regret. But how does the science actually work? » 4/02/13 1:54pm 4/02/13 1:54pm

Comparing the Universe To the Pixels In This Video Puts Its Massive…

Taking advantage of its medium of choice, Minute Physics makes the incredibly vast scale of the observable universe a little easier to comprehend by comparing it to the 2,073,600 pixels in this 1080P video. But be forewarned: drawing similarities between the earth and a single pixel in this clip isn't going to help… » 3/11/13 5:20pm 3/11/13 5:20pm

Just How Incomprehensibly Massive Is the Universe? (Hint: Even Bigger…

Have you ever stared up at the stars and wondered just how far you'd have to travel before you reached the edge of the universe? The answer—as Minute Physics illustrates—is far. Like really far. Like somewhere in the neighborhood of 46 billion light years starting wherever you're standing. » 2/25/13 4:40pm 2/25/13 4:40pm

What Is the Universe? (In One Minute)

What is the Universe? Is the Universe everything there was, is and will be? Is the Universe everything we can observe and things we know exist but haven't been observed yet? I mathematics part of the Universe or do they exist outside of the Universe? This one-minute-long video shows exactly what the Universe is—but… » 2/16/13 6:30pm 2/16/13 6:30pm

What Would Really Happen if an Unstoppable Force Met an Immovable…

The Joker thought he had found the answer while dangling at the end of The Dark Knight, but have you ever really wondered what would happen when an unstoppable force meets an immovable object? The folks at Minute Physics did, and as usual brought a mountain of entertaining science to explain how such an interaction… » 1/25/13 9:24am 1/25/13 9:24am

In Case There Was Still Any Doubt, Here's the Top Ten Reasons We Know…

At this point it's hard to find a skeptic who would raise an eyebrow at the notion that our planet is round. But every family has that one uncle or cousin who's so caught up in conspiracy theories they'll question anything. And if you happen to find yourself in a tedious argument defending the spherical nature of… » 1/01/13 1:00pm 1/01/13 1:00pm

Do You Get Less Wet Walking or Running in the Rain?

It's one of the more interesting thought experiments to ponder when you're stuck inside on a dreary day, but Minute Physics finally breaks out the math and science to determine once and for all if walking or running through the rain will keep you the most dry. » 12/20/12 8:41am 12/20/12 8:41am

Is There Poop on the Moon?

Everyone always talks about the wonders of space: its vastness, its complexity, and how exploring it is stretching the limits of human endeavor. Oddly, nobody ever talks about what astronauts do with their poop. » 12/14/12 6:49am 12/14/12 6:49am

Gravity Doesn't Work How You Think It Does, And Other Common…

Most of us grew up believing that gravity is just the mass of two objects attracting each other. We probably still think that, really, since who spends their time reading up on gravity? Well, that's WRONG. » 12/06/12 9:40am 12/06/12 9:40am

Here's What's Missing from a High School Physics Education

If you want to be a world leader in science and technology, it's important that your kids learn all about the science that makes technology work, right?

Will We Ever Be Able to Predict Everything?

As super computers get more and more super, you'd think that eventually we'd be able to calculate the position and interactions of every atom in the universe and be able to accurately predict the future. In fact, this was once a widely held belief in science, until quantum mechanics arrived and put an end to that… » 11/05/12 8:23am 11/05/12 8:23am

How Quantum Mechanics Was Born From the Need For a Better Lightbulb

Some of mankind's most remarkable scientific discoveries came to light as a result of research that had nothing to do with the breakthrough itself. And such was the case with quantum mechanics. Back in the early 1890s the German Bureau of Standards asked Max Planck to design a lightbulb that produced the maximum… » 10/15/12 8:28am 10/15/12 8:28am
