Simon is interested in space again, since he has gravitated towards Physics and has been learning a lot of astrophysucal concepts. We had times when he didn’t bother to join … Continue reading Looking at the Moon and Mars
We built a water fountain powered by sound waves! There is a little speaker attached to the bottom of the water basin. Warning: the sound frequencies in the video may … Continue reading Water Fountain Powered by Sound Waves
What looks like strange planets in dark space are actually glimpses of the microstructures forming the Giant Blue Morpho’s wings, as seen through a microscope. Simon told me about how … Continue reading Microstructures Interfering With Light
Going for a walk quickly turns into yet another Physics experiment. “Here’s a challenge: what if you can force the ball down so much and induce so much horizontal motion … Continue reading Horizontal force
Simon is baking Dutch traditional “pepernootjes” (“pepper nuts” or spicy cookies) and explains why they get bigger in size after you put them in the oven and what the optimal … Continue reading Why Cookies Get Bigger in the Oven
Simon told me this morning that he has found the answer to a question that bothered him so much lately -why photons (and gluons) violate E = mc². “It’s because … Continue reading Serious answers
Mom, did you know there’s a density limit? Density is mass divided by size! If an object reaches the density limit it will become a black hole. If you have … Continue reading No Limit
Simon really wanted to try building a capillary bowl – a version of a perpetual motion machine in which water circulates. Although aware of the fact that perpetual motion was … Continue reading Physics Experiments: Capillary Bowl
Simon isn’t fond of magic or fantasy. Plus, he is not fond of long walks in the woods. Both “not fond of” are understatements. What was I counting on when … Continue reading Photons Trapped in Flemish Woods
“Are you impressed?” – Simon asks, laughingly, and I can see it must be a pun. We are in bed, reading up on Newton’s laws of motion that talk of … Continue reading Impressions on Newton’s mechanics.
