Is it a particle or is it a wave?
Posted by: ozymandias1 on: October 6, 2010
Sometimes I think I’d gladly be locked up in a dungeon ten fathoms below ground, if in return I could find out one thing: What is light? Galileo, from the play Life of Galileo, by Bertolt Brecht The single greatest source of debate among physicists in the early decades of the last century was to [...]
Ernst Mach: the problem with Science Education
Posted by: ozymandias1 on: January 15, 2009
1859 marks not only the 150th birthday of the publication of Darwin’s On the Origin of Species, but also a somewhat less well-known occasion; It was the year Ernst Mach published the first of his 500 publications (his last was published five years after his death, in 1921). Most will know of this man through [...]

We had half a class the other day so we just played around with some equipment left lying about. One such piece was a cardboard disc with black circles and shapes on a white background. If you spin it quickly you get to see coloured circles! It’s mad I tell you. Only thing is, because it’s got [...]

A colleague reminded me recently that when you think about it, there are really only two concepts that fascinate young kids; Space and Dinosaurs. Okay, so this is a gross generalisation, but with work with me here. Somebody in England has cottoned on to the first part of this. The Society for Popular Astronomy (SPA), [...]

I must get around to talking about the Physics of what’s happening here at some stage. I just figured nobody would be too interested on the day.

I needed to start puting together resources for Junior Cert Physics, so I started with some simple ideas for teaching Electricity. I lost it just a little at the beginning but decided to include it in case people got to thinking that all my classes are perfect - far from it.
It’s been a pretty cool few days

After a number of months of trying (off and on, mind), I finally managed to get the url for the blog changed to thinkforyourself.ie Thanks to my colleagues at St. Columba’s College English department for the idea. After putting in quite a bit of work into Young Scientist Projects for the first time this year, we [...]
Unusual resource for explaining Joule’s Law
Posted by: ozymandias1 on: October 23, 2008
An offshoot of Joules’ Law is that when transmitting electrical power, the current is kept as low as possible in order to reduce energy losses associated with heat of the electrical cables. Because the power being transferred is the product of the voltage and the current, we can still get the same power transferred if [...]

Tom Healy teaches Physics in Cabinteely Community School and for quite a while now has been uploading revision videos on Leaving Cert Physics to youtube. He has almost 50 up there by now and has divided them into Mandatory and Non-mandatory experiments. A wonderful way to revise, but also a wonderful resource for any new teachers. [...]
