The more you know about a quantum particle's position, the less you know about its momentum, and vice versa. This is the Heisenberg uncertainty principle, and I thought it applied to quantum particles only, so I didn't mind not understanding why this was so because quantum physics is weird. But 3Blue1Brown says the Heisenberg uncertainty principle applies to non-quantum things to, and in this 20-minute video, he explains why. You can actually get a reasonably good understanding of the uncertainty principle by watching the first two minutes of the video.
Quantum physics gets real weird real fast, and one idea gaining more currency of late is the concept of quantum retrocausality, where a decision made in our experience of the present may influence what we experience as the past. These aren’t a bunch of Time Cube type cranks, either. From a helpful overview by Lisa […]
Chinese researchers demonstrated quantum entanglement at a record distance, between a satellite and ground stations 1,200 kilometers apart. When objects are quantum entangled, their quantum states are linked. Measuring the state of one affects the state of the other. It’s weird shit. So weird that Einstein called it “spooky action at a distance.” The experiment […]

These days, there isn’t much our iPhone camera can’t do – except feel like an actual phone. Despite years of steadily increasing resolution and image sensing technology, we’re still taking shots awkwardly with two hands, fumbling for the shutter button. Leave it to an avid photographer to design Shuttercase, a versatile iPhone case that solves […]
Still determined to keep those New Year’s health resolutions? If you’re going to stick with the exercise plan, it’s enough of a challenge to budget your time. No need for your financial budget to take a hit, too. Here’s a more convenient – and cheaper – alternative to a gym membership or Peloton bike: Two […]
