Physicists at the University of Washington have recently proven, without the shadow of a doubt, that a cold drink warms up when the air is warmer. And no, this has nothing to do with the temperature, because that would be too obvious. Instead, the underlying physics has something to do with the latent heat of vapourisation.

A few days ago, some students asked what would happen when an unstoppable force meets an immovable object. It was an innocent question, but one that caused the whole class to stop work and ponder on the answer. Since the class was supposed to cover a whole different topic on physics (thermal transfer), I decided to answer the question, under the condition that we had to finish the topic before going through the physics behind the force and the object.
When I was taking a break in Bali, I came across a place with a glass tank for a ceiling. The water in the tank was oscillating with the wind, and the sun was in the perfect place its light to shine down from the sky to the floor. It was a marvel by itself, and then I looked at the floor.

2008. I was having trouble with keeping up with classes. The reason: every teacher’s chronic request – more time. At that time, I was teaching secondary General Science. So I decided that I need a blog. The blog was about General Science, tailored to what I wanted to cover in order to catch up with lessons. Read the rest of this entry →
German physicists working on secure data connection have developed an improved method to transmit data securely from one computer to another, using the ideas of quantum mechanics. Read the rest of this entry →
I’ve been teaching physics to kids for at least seven years. I know that’s not a long time in absolute terms, but it’s pretty amazing what you can pick up and learn over such a time span. There’s a lot of things that can be done, either to link different areas of study, or to make one point last long. And so, here’s the big pitch: Not only will I be posting stuff related to learning physics (and science in general), but I will also be posting stuff on how to teach physics in a manner that works efficiently.
There’s also gonna be a new look to the site, as I have received feedback that the last one did not have an intuitive feel to it, especially in terms of clicking and reading through articles. Most of that feedback came from my students. I do feel that there is some wisdom in a young one’s requests (like this story about Harry Potter author J.K. Rowling), so I have turned it back into a click-and-read site.
Finally, I now have some time I can use to update the site again. Since the last time, I have had several ideas, which I wanted to either write down or share, but just could not do so. So here’s to a few new things to look forward to. Thanks for sticking around!
A few months ago, that something new came up as a section: the What If? page. It’s as simple as it sounds. What if _________________? Most of the time, site readers submit the questions and one gets answered every week.
Here’s one of my favourites. It’s such a simple question, but with a lot of physics in it. Here you go…
If you enjoyed that, just keep reading. There’s a lot to go through, and more coming every week!
