Mesmerized by the Borealis installation. As part of the Cambridge Science Festival last weekend, Dan Acher recreated the Northern Lights right above the MIT Open Space on Kendall Square. Dan … Continue reading Cambridge Science Festival
Last night I was granted one of those magical bedtime conversations with Simon that we share every now and then, about the nature of the universe. We were reading Randall … Continue reading Photons are not to Be Taken Lightly
Simon’s way to celebrate Helloween: a little demo about how red marker reflects red LED light and becomes invisible. A nice trick in the dark! We also had so much … Continue reading Vanishing Letters
Here Simon explains one more effect he has played with at home, the Magnus effect.
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
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
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
We were reading Steven Hawking’s A Brief History of Time, and Simon asked: “If the speed of light is the same relative to any body, is it the same relative … Continue reading What Does it Feel Like to Be Light? And Why the Infinity Tunnel is Actually Finite.
Simon tests how well different light waves travel through the minuscule hole of the camera obscura.
Simon has been fascinated about the Opponent-process theory (suggesting that color perception is controlled by the activity of three opponent systems, three independent receptor types which all have opposing pairs: white … Continue reading Electromagnetic Spectrum and the Opponent-process Theory
