Happy Birthday, Oliver Heaviside
At the age of 16, Oliver Heaviside’s formal education came to an end. However, he went on to discover the first coaxial cable, the modern Maxwell’s equations, and the Kennelly–Heaviside layer.
The Science Behind Plant-Based Foods
You have probably heard of almond milk, coconut milk, and oat milk. But are you familiar with potato milk? This milk substitute hit grocery shelves in Europe in early 2022.
A Novel Technique for Producing Ultrastrong 2D Polymers
A group of materials science researchers have developed a new polymerization technique for producing strong and lightweight 2D polymers (a creation that was thought to be impossible!)
Happy Birthday, Norbert Rillieux
Sugar has been around for centuries, but the revolution in sugar processing occurred less than 200 years ago. Learn about the life and work of the engineer behind this revolution.
Happy Birthday, Ralph Fowler

Happy Birthday, Joseph Petzval
In 1840, this Hungarian physicist introduced a lens design that could gather more than 20 times as much light as lenses used in earlier cameras.
How Long Does It Take an Engineer to Turn on a Light Bulb?
Misconception about electricity: Electrons carry the energy in an electrical circuit. Today, we investigate this theory with simulation.
The Science Behind Lie Detector Tests
Polygraph machines accurately monitor cardiovascular, respiratory, and electrodermal activity. But can they really determine whether a subject is being deceptive?
5 Fun Facts to Celebrate Fibonacci Day
Fun fact: The Fibonacci sequence can be found in flowers, pine cones, tree branches, and shells.
Möbius Strips: Where Math Meets Art
The Möbius strip was simultaneously and independently discovered by two German mathematicians in the 1850s. Today, this one-sided object is found in tools, art, nature, and more.
Extracting DNA: From Pumpkins to Mammoths
Here, we go over how to recover DNA from a pumpkin using a simple experiment, as well as how scientists made a recent breakthrough in DNA extraction research.
Happy Birthday, Adhémar Jean Claude Barré de Saint-Venant
The shallow water equations, a derivation of the Navier–Stokes equations, and Saint-Venant’s principle can all be credited to French physicist Adhémar Jean Claude Barré de Saint-Venant.
The History and Science Behind Vinyl Records
As vinyl records explode in popularity, we take a look back at the history of records, as well as the interesting science behind how they are produced — and how they play music.
Happy Birthday, Egon Orowan
Egon Orowan found that the theory of dislocations could be used to explain the plastic deformation of ductile materials. He also studied geological fracture, munitions production, and more.
Happy Birthday, John Sealy Townsend
From fluorescent light bulbs and Geiger counters to plasma televisions and semiconductor manufacturing, Townsend discharge has many important applications. Who discovered this phenomenon?
Why Do Pigeons Have Iridescent Feathers?
If you look at a pigeon a certain way, the feathers around their necks shine in bright hues of emerald and amethyst. As it turns out, a prehistoric animal exhibited a similar trait…
