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
Chaos Game and the Serpinski Triangle
Monday morning Simon showed me the Chaos Game: he created three random dots on a sheet of paper (the corners of a triangle) and was throwing dice to determine where … Continue reading Chaos Game and the Serpinski Triangle
A lot of fluid dynamics at Technopolis
Here Simon explains one more effect he has played with at home, the Magnus effect.
Experimenting with random walks in Wolfram Mathematica
Simon’s code is published online at: https://www.wolframcloud.com/objects/monajune0/Published/Random_walk_distribution.nbhttps://www.wolframcloud.com/objects/monajune0/Published/Random_walk_distribution2D.nb “If I take many random walks and see what the endpoints of those random walks are, what I’ll find is a Gaussian distribution!” … Continue reading Experimenting with random walks in Wolfram Mathematica
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
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
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
Physics Experiments: Making Holes in Soap Membrane
This demo is inspired by a recent video on Steve Mould’s channel. It’s about creating a movable hole in soap film with a loop of cotton thread (the photo shows … Continue reading Physics Experiments: Making Holes in Soap Membrane
MEL Chemistry Experiments: Making Batteries
We did two more experiments a couple days ago: Liquid Wires (creating a simple circuit using graphite and liquid glass, a sodium silicate solution) and making our own Zinc-Carbon Battery, … Continue reading MEL Chemistry Experiments: Making Batteries
