Light pollution is contributing to worldwide insect decline and that’s actually a huge problem. Insects may seem pesky. They bite and sting […]

DIY Home Energy Monitor & CT sensors explained

Hi everyone! This is a bit of a special Simply Explained video with me talking about my DIY home energy monitor and how I built it. You see I was interested in measuring how much electricity our whole apartment was using and I wanted to collect that data over time. Now, of course, I could […]

5 of the Best Measurements In Science

[ intro ] If you take all the humans who have ever lived, then, all told, members of our species have probably witnessed around a quadrillion sunrises — give or take. That’s a quadrillion tests of the hypothesis that the sun rises in the morning. Today’s humans use what’s called the Standard Model of particle […]

Hubble Spotted New Evidence That Dark Matter Is “Cold”

Cosmologists know that dark matter must exist. If it didn’t, the rate galaxies spin would tear them apart— so there must be something unaccounted for generating the gravity that’s holding them together. Something that doesn’t interact with regular matter in any other way that we’ve detected yet. What exactly that something is, is anyone’s guess—and […]

This Is the Biggest Neutron Star Collision We’ve Ever Detected

Gravitational waves resulting from crashing neutron stars have rocked our universe once again. And while you may not have felt it, LIGO sure did. And these gravitational waves are the ripples from a collision of the most massive neutron star pair we have ever witnessed. As you may know, this isn’t LIGO’s first rodeo with […]

Day 69: Electricity From Air

Hey guys! And welcome to Goodness! Today’s Goodness is about a generator that produces electricity from air! Or more accurately, fluctuations of temperature in the air! Researchers from MIT have created a thermal resonator that harnesses the movement of energy and particles when temperatures change which means they can create electricity just by putting the […]

What Does It Take to Enrich Uranium?

Nuclear programs are constantly in the news, with reports that they’re enriching uranium. Usually, the stories mention percentages and centrifuges, but to the uninitiated, it’s not clear why these things are important. What exactly does it mean to enrich uranium? And at what point should we be worried? Now when I imagine enriching uranium, I picture […]

Earth’s Magnetic North Pole Is Shifting South… So What Now?

You may have heard that the earth’s magnetic poles tend to move around. I mean, so do the geographic poles, but magnetic North and South are really mobile…and magnetic North in particular is moving real fast. Like, way faster than we thought it would. And the scientific community is coming up with some really exciting […]
