The Hubble space telescope was launched on April 24th 1990 on the space shuttle Discovery.

Earlier this month Hubble was pointed at a pair of interacting galaxies known as ARP 273 …

Some Physics Advice…
When I want to remember how to correctly spell practice or practise (which I do all the time) I remember the sage words of a former colleague who used to say, “Advise is a verb and advice is a noun.” This was good advice and I advise you to heed it when writing the word practice (the …

Ah, Hollydogs Again…
I hope you are all beginning to relax after the stresses of term. I am out in France for the first time since October and am having to convince an army of flies that this is my place not theirs. They are taking some convincing but I think that I am winning. Over the next …

Graphs can show trends in data and help you to predict possible future outcomes. The more data you collect the more accurate your graph is likely to be, allowing you …

Origin Of The Universe…
Something a little less exam-oriented but interesting stuff nonetheless I hope. This video from Minute Physics discusses what we do and do not know about the origins of the Universe. We make observations and draw conclusions. Hopefully what we don’t do is look for areas of uncertainty and then make up an explanation. It’s OK not to …

When I was a student, there was no Internet, at least not as we know it today. I got my information/entertainment in printed form. In Newcastle there was a fringe underground magazine that I bought weekly – it was a little like Private Eye but for juveniles. My favourite section was the Top Tips page. …

Radley…
I had a good time at the Radley Prep School’s Science Day yesterday. It is always a good opportunity to talk to other prep school science teachers and to talk to the people who may be teaching you in the future. We spent some time talking about the chemistry CE paper, and CE in general, with the man responsible …
