I’ve found a useful Chemistry/Biology tutor for all you science students out there


David Davis

here he is doing stuff on his site about energy flows:-

And here’s his main blog:-

We like numbers, we like playing with them….


…to find the truth.

The new Bentley Continental thing, you know, that car that the GreeNazis don’t want you to own? Well, it !”squirts out 338 grams of CO2 per Kilometer, that’s about 9 moles (a mole of it being 44 grams) at STP. Nine moles of any gas, as everyone knows, is about 9 cubic feet, give or take. You could easily get all of it into an average fridge.

So, your Bentley gives out about a fridge and a half of COs per mile. And they are complaining?

It must use, then, about a mole and a half of ordinary petrol, defined arbitrarily as nonane, per mile. And that’s the lot, even the stuff used to turn the engine over and keep it warm…About 120 grams: so what’s the beef?

Here’s the chemistry. It’s called CHY1A (Higher).

And here’s the “mark scheme”:-

I’ll leave you all in suspense for a couple of hours about the physics.

If you go here, then you  _might be able to_ hack past the “secure download” username/password thingies, to get at “Edexcel” papers too. They won’t let you download these unless you are a British State Apparatchik teacher in a scumbag-school with a password. You see, the State does not want you to help your child do well, if your are a mere parent, or even if you are the independent child, looking for yourself.

Tony, can you get onto this one please, and crakc it maybe?

UPDATE2:- It’s no use merely moaning and whingeing as I am doing here. Even by bringing this more to people’s attention, we can change little in a hurry. The State has not only taken Nazi ownership of our children, but has also intellectually cast them adrift at the same time, and it’s all probably deliberate.

The remedy is to live with them in a houseful of books, use the said books liberally in front of them while making sure that these are text books about real stuff and not pretentiously awful Booker-novels, and discuss with them scientific discoveries and the history of same at mealtimes.

UPDATE1:- From Driver Rob, this is fine stuff and I agree totally. I also use “old” O-level (remember that?) text books to support A2-students of 18 in maths, and “old” GCSE science ones from the 80s and the pre-Blair-90s in general, to cover random GcSE/AS/A2 work from the ages of 15-19.

This one’s biology: it is astonishingly appalling in its lack of interest in biological knowledge, and its insistence upon knowledge of the principles of dictated social behaviourism, and, er, sociology.

I’ll put up a chemistry paper later tonight: then you’ll really worry. Then, later, a physics one: you will go hysterical.

I just thought we needed a laugh.

For the benefit of foreign readers in proper countries, this is a sample of what’s been done to our science education, by our government, while we slept. Don’t go to sleep, while your government fiddles with your education setup, whatever it might be, while your back is turned.

Governments ought not to be trusted to “run education”, not anywhere, and not at any time, ever.

I follow this interesting and quite libertarian blog from time to time, having first had them brought to my notice over the tragedy of the disappearing Chemistry Sets (about which I have sadly done nothing useful yet.) They have a later post about this grave matter here, and there may be others I have not yet found.

Pretending, as I do, to teach Science in my retirement, I always get a thrill from watching the faces of students, when we do something pretty, coloured or explosive, such as one of these:-

I can’t afford Potassium, so we do it with Sodium instead, which is less horrendously expensive.

The little buggers like this one too:-

I have not yet tried this one, but may take it with me next week:-

They love this one. On the TV prog “Brainiac”, it is called “Peter Logan’s exploding paste”:-
