We’ve found the real 0° meridian!
And it turned out to be a that little path next to the Royal Observatory in Greenwich, not the Prime Meridian line. The 0° meridian is what the GPS uses … Continue reading We’ve found the real 0° meridian!

All Nerds Unite: Simon meets Steve Mould and Matt Parker in London
Hilarious, inspirational and loaded with cosmic coincidences, this was one of the best evenings ever! Many of our currently favourite themes were mentioned in the show (such as the controversy … Continue reading All Nerds Unite: Simon meets Steve Mould and Matt Parker in London

The Brachistochrone
Simon believes that he has found a mistake in one of the installations at the Technopolis science museum. Or at least that the background description of the exhibit lacks a … Continue reading The Brachistochrone
A lot of fluid dynamics at Technopolis
Here Simon explains one more effect he has played with at home, the Magnus effect.
Simon’s Community Contribution: Variation of 2D Casting Coding Challenge in p5.js
This is Simon’s version of Daniel Shiffman’s 2D Casting code, made on Wednesday last week right after the live session. Link to the live session including the coding challenge. Code … Continue reading Simon’s Community Contribution: Variation of 2D Casting Coding Challenge in p5.js
Chemistry Experiments: Polarized light iridizes crystals
Today we have made beautiful rainbow chrystals! Polarized light iridizes sodium thiosulfate crystals, so we made the crystals in between two polarizing films and then observed them through the microscope. … Continue reading Chemistry Experiments: Polarized light iridizes crystals
Black Hole Breakthrough
Caught Simon’s reaction to Wednesday’s breaking news on video: the first-ever image of a black hole published, made by the Event Horizon Telescope project team. Simon explains why, if you … Continue reading Black Hole Breakthrough
Physics Experiments: Using an LED backwards
We have tried using an LED backwards: not get it to shine by letting an electric current pass through it but produce electricity by shining light on an LED (this … Continue reading Physics Experiments: Using an LED backwards
Physics Experiments: Stroboscopic Effect
Simon showed us this amazing hing with a fidget spinner. It’s called stroboscopic effect. It’s a visual phenomenon that occurs when continuous motion is represented by a series of short or … Continue reading Physics Experiments: Stroboscopic Effect
How do 3 gear work?
Mesmerised by the 3D printed gears on Numberphile: “If you move two of these, the third one appears to be hovering in mid-air!”, Simon made a similar construction of his … Continue reading How do 3 gear work?
Physics Experiments: Double Slit
We have wanted to do the Double-Slit experiment for a long time. Finally, last Friday, armed with a suitable box, we ventured outside. To our common disappointment, light just wouldn’t … Continue reading Physics Experiments: Double Slit
