My satellite dish was fixed on Wednesday. There were men on my roof and everything! So I have Sky working again after an extended drought of about 5 months. I needed something intellectually stimulating so put on Dave in the hope of an old episode of QI. Instead, I saw something completely new to me …

During the IPL cricket match I watched yesterday, the commentators spoke to Dr Daniel Harris who was wearing a microphone on the field for the Deccan Chargers. When not playing cricket he is a hospital doctor and I thought that this was pretty unusual. I can’t think of very many sports stars with a science background. …

Lego is a 3rd declension verb that goes like rego (rego, regere, rexi, rectum – has there ever been a funnier verb?). There’s a jolly website here that is full of third declension related fun and frolics. It seems to mean variously; I read, I pick out, I choose – but I am sure that you are much …

Just easing myself back into blogging mode after the end-of-term bedlam, I could not decide between a response to the LHC colliding particles at 7TeV, which I watched live on the Internet yesterday, or a spoof video clip about scientists teaching animals to embrace the impermanency of existence. Since the former required work and the …

The balanced equation for the combustion of ethane in oxygen is C2H6 + 7O2 –> 2CO2 + 3H2O. Therefore, we need to destroy 12 C-H bonds and 7 O-O bonds. This requires (12413) + (7498) = 8442 KJ of energy. The joining of the bonds requires 4 C-O bonds and 6 H-O bonds. This requires …

Distribution Graphs…
When 8R & 8L have done their power experiment, we can plot a distribution curve showing how much variation there is in power between members of Y8. Normal distribution describes the range of outcomes when collecting data during experiments. Some of the numbers will be larger than the average and some will be below average …

It’s time to start getting ready for term so no more new posts now until Long Leave. Very well done if you have read the last 14 posts and clicked on the associated links. Even better if you have engaged in the discussion – that’s the most important bit. I normally finish with an intellectual …
