Graphical relationship between acceleration, velocity and displacement I created the following GeoGebra app to illustrate the relationships between the physical quantities acceleration, velocity and displacement. Modify the acceleration graph using the two green dots. Notice how the velocity and displacement… Continue Reading

The recently launched Apple AirPod Pro presents a wonderful opportunity to relate an A-level concept to a real-world example – how noise-cancelling earphones work. Apple’s website explained it in layman terms that seem to make sense. Let your students attempt… Continue Reading
I was looking for an extension to the Micro:bit Go set that I bought a while back and came across a robot set that is currently on sale. This set comes with most of the sensors a typical line following… Continue Reading
https://www.seriouslyscience.sg/one-north-Festival/Overview Happening now from 13-14 Sept 2019 at one-north. My colleagues and I took the opportunity to visit the exhibitions during lunch time today. I learnt about 3M’s solar films and retroreflection material, I^2R’s speech-to-text recognition app with code switching… Continue Reading
This is a free public lecture by Dr Nergis Mavalvala (an astrophysicist from MIT) on how her team detected gravitational waves generated from colliding black holes and neutron stars at the Laser Interferometer Gravitational-wave Observatory (LIGO). Held on this coming Friday 26… Continue Reading
This video relates a phenomenon that we have taken for granted to the study of quantum physics (more specifically, photon absorption) and atomic structure.
I created a series of GeoGebra apps for the JC topics of Waves and Superposition, mainly on the concept of Phase Difference. The sizes of these GeoGebra apps are optimised for embedding into SLS. When I have time, I will… Continue Reading
Here’s a good explanation by Veritasium on why the image of the black hole looks the way it does.
