[The Signal Path] shows us how to recreate a classic science experiment to measure the weight of an electron. Things are easier for us, because unlike [J. J. Thomson] in …read more Continue reading Does this Electron Make Me Look Fat? Weighing an Electron
While it has become a word, laser used to be an acronym: “light amplification by stimulated emission of radiation”. But there is an even older technology called a maser, which …read more Continue reading The Amazing Maser
There was a time when making a cloud chamber with dry ice and alcohol was one of those ‘rite of passage’ type science projects every nerdy child did. That time …read more Continue reading Desk Top Peltier-Powered Cloud Chamber Uses Desktop Parts
[Stoppi] always has interesting blog posts and videos, even when we don’t understand all the German in them. The latest? Computer simulation of wave propagation (Google Translate link), which, if …read more Continue reading Models of Wave Propagation
There are (probably) less than two dozen fundemental constants that define the physics of our universe. Determining the value of them might seem like the sort of thing for large, …read more Continue reading Determine Fundamental Constants with LEDs and a Multimeter
Science fiction authors and readers dream of travelling at the speed of light, but Einstien tells us we can’t. You might think that’s an arbitrary rule, but [FloatHeadPhysics] shows a …read more Continue reading You Are Already Traveling at the Speed of Light
Lego! It’s a fun toy that is popular around the world. What you may not realize is that it’s also made to incredibly high standards. As it turns out, the …read more Continue reading Building an Interferometer With Lego
Is fire conductive? As ridiculous that may sound at first glance, from a physics perspective the rapid oxidation process we call ‘fire’ produces a lot of substances that can reduce …read more Continue reading Is Fire Conductive Enough To Power a Lamp?
We are deeply intuitively familiar with our everyday physical world, so it was perhaps a bit of a surprise when researchers discovered a blind spot in our intuitive physical reasoning: …read more Continue reading Turns Out Humans Are Terrible At Intuiting Knot Strength
The Brennan torpedo, invented in 1877 by Louis Brennan, was one of the first (if not the first) guided torpedoes of a practical design. Amazingly, it had no internal power …read more Continue reading Pulling Backward to Go Forward: The Brennan Torpedo Explained
