Science Minister can't answer questions about Science because of his Religion

A Canadian Science Minister Gary Goodyear was asked whether he believed in evolution. His response?

I'm not going to answer that question. I am a Christian, and I don't think anybody asking a question about my religion is appropriate,

What?!?

Imagine the situation: an economics minister is asked "Do you believe that increasing the minimum wage helps poor people?". His response: "I'm not going to answer that question. I am a Keynesian and I don't think anyone asking a question about my Economic Beliefs is appropriate".

This is just too completely ridiculous for words - if your religious beliefs affect your ability to do your job, then asking questions about them damned well is appropriate. Given that he didn't answer the question, this guy presumably is some sort of creationist, and this is certain to affect his decisions regarding funding for biology (evolution is the organising principle of the whole of modern biology - if you don't believe in it, you have to throw the whole lot out of the window). There is no reason why religious beliefs should sacred (and yes, I know that's a bad word, but I never have been able to think of a better one), any belief which makes you incapable of doing your job is fair game.

CPS takes ridiculous law to its logical conclusion

According to the Mail on Sunday, the CPS has decided to treat Scientology in the same way as other religions when it comes to protections under the Race and Religious Hatred Act.

Now, don't get me wrong - Scientology is a really, really stupid religion - for God's sakes, it was founded by a man who said (something like)

"You don't get rich writing science fiction, if you want to get rich, you start a religion"

For more on this quote, see here - to quote that page:

To summarize: we have nine witnesses: Neison Himmel, Sam Merwin, Sam Moskowitz, Theodore Sturgeon, Lloyd Arthur Eshbach, Harlan Ellison, and the three unnamed witnesses of Robert Vaughn Young. There is some confusion and doubt about one of them (Sam Moskowitz). Two are reported via Russel Miller: one is reported via Mike Jittlov: one reported in his autobiography; one reported in an affidavit; and one reported to me in person. The reports describe different events, meaning that Hubbard said it perhaps six times, in six different venues - definitely not just once. And the Church's official disclaimer is now reportedly a flat lie.

It's a really, really stupid religion, it has some utterly ridiculous beliefs as part of its credo, and it does some pretty nasty things to people - but that's not my point here (there are other people far more qualified to comment on the stupidity and cupidity of Scientologists than I am. My point is that if you have laws which explicitly protect religious belief, then you're going to have to use them to protect "religions" like Scientology.

There's no evidence whatever that aliens flew to Earth in DC-8's, but then there's no evidence whatever that people can survive for three days in the belly of a whale, or that any of these things actually happened.

Taken at face value, almost all religious beliefs are ridiculous, and since religions don't demand any actual evidence for their beliefs, just about the only way to distinguish between a religion and a cult is that a religion has more members. This is something I've written about before, and I think it's quite important, and often missed by other people who write about this sort of thing. Once you start to officially recognise one form of unsupported nonsense, you're on a slippery slope to having to officially recognise whatever form of unsupported nonsense people happen to want to believe in tomorrow.

FSA thinks we're all *really* stupid

There are some new posters up around Whitechapel to encourage healthy eating - not sure if they're made by the FSA or by the local council. Anyway they have some really excellent health tips on them. So far I've seen:

Eating less pastry can help reduce your saturate fat intake.

Mildly patronising, but I suppose possibly useful for people who might not know that pastry is high in saturated fats.

Swapping olive or vegetable oil for butter in cooking could help reduce your saturated fat intake.

Well... ok, if I don't cook with saturated fat as much then I won't get as much saturated fat in my diet. Again, I suppose this could theoretically be useful for people who didn't realise that vegetable oils are healthier than butter (which people these would be, exactly, I wouldn't like to say).

Simply eating healthier snacks can help reduce your saturated fat intake.

Now we're getting really patronising. Since in order for this to make sense healthier can only be defined as "containing less saturated fat", this is almost tautologous, and surely not actually new information for anyone. In fact, after seeing this sign, I suggested (in jest) to my friend that they should just put up a sign which said "eating less saturated fat could reduce your saturated fat intake."... which leads us onto the latest one I've seen:

Just reading labels and choosing options which are lower in saturates could help lower your saturated fat intake.

Yes, seriously, someone thought it was a good idea to put that on a poster. Once again, to paraphrase, because I can't imagine anyone stupid enough that this poster would actually benefit them: "eating less saturated fat could help reduce your saturated fat intake". Is it possible that there's someone out there in the world who is intelligent enough to read a poster multisyllabic words like "saturated" and not intelligent enough to realise that if they want to reduce their saturated fat intake they should eat less saturated fat? I think I've probably repeated myself too much in this final paragraph, but I just can't get over the inanity of this poster campaign - seriously, how stupid does the FSA think we are?

Of course, all this is assuming that reducing saturated fat intake is a good thing, which I am led to believe is far from proven. I'm not an expert, I don't claim Rob Grant is an expert, and I'm not about to claim that the FSA is definitely wrong, but there are certainly well-qualified people out there who are not convinced that a diet high in saturated fats actually does increase blood cholesterol levels (or that this would necessarily be a bad thing if it did). Why doesn't the FSA spend money researching this instead of placing highly irritating and patronising posters on the Tube?

Former Greenpeace Head sees sense on Nuclear Power

For years I (and no doubt many other people) have wondered why on Earth environmentalist groups who claimed to want to reduce carbon emissions spent so much of their time opposing the only feasible alternative to carbon-based fuels - nuclear power. Finally, it seems, they are starting to see the light. In an article for the Independent, Steven Tindale (a former head of Greenpeace) and three other leading environmentalists come out in favour of nuclear power. Tindale said:

“It was kind of like a religious conversion. Being anti-nuclear was an essential part of being an environmentalist for a long time but now that I’m talking to a number of environmentalists about this, it’s actually quite widespread this view that nuclear power is not ideal but it’s better than climate change.”

That 'religious conversion' point is particularly telling. Steven Landsburg argued years ago that environmentalism was never about saving the environment, it was about following the cathecism.
Things which 'sound' wrong have always been opposed by environmentalists whether they would be a good thing or not - look at Tindale's 'Being anti-nuclear was an essential part of being an environmentalist'. This is certainly something that happens in other areas - I remember when I was a member of an anti-war group in Birmingham, it was widely accepted that in order to oppose the Iraq war you had to oppose the Israeli occupation (I had no problem with that, but why the two should be inherently linked, I have no idea), and it's both irrational and damaging to the cause.

Landsburg's classic example of a basic tenet of enviornmentalistm that may or may not have anything to do with the good of the environment is recycing paper. There is at least a possibility that recycling paper reduces the total number of trees on the planet, by making owning trees less profitable - this may or may not be true, but how many environmentalists would even bother to entertain the notion. Recyling is a Good Thing, wasting paper is a Bad Thing - and you will be shunned for suggesting otherwise (seriously - try it with one of your green friends some time).

Conformity bias is a powerful force, as is consistency bias - the fact that four powerful figures have changed their minds about such a major issue is surely an encouraging sign for environmentalism - whether or not nuclear power is a good thing (I'm pretty convinced it is, but that's not the issue), it's good that environmentalists are willing to actually look at the facts, maybe one day they'll even give their backing to GM....

The Perfect Pancake

Ok, so I'm probably not the first, and I'm sure I won't be the last, to deconstruct this utterly ridiculous formula, but I mean, seriously... which utterly ridiculous formula you may ask? There are, of course at least two a week in the Metro. Well, for now let's do this one. Dr. Ruth Fairclough who is a "maths expert" and teaches at Wolverhampton University has come up with the following formula for the perfect pancake:

Dr Ruth, who teaches at Wolverhampton University found that
100 - [10L - 7F + C(k - C) + T(m - T)]/(S - E) created the tastiest snack.

In the complex formula L represents the number of lumps in the batter and C equals its consistency.
The letter F stands for the flipping score, k is the ideal consistency and T is the temperature of the pan.
Ideal temp of pan is represented by m, S is the length of time the batter stands before cooking and E is the length of time the cooked pancake sits before being eaten.

The closer to 100 the result is - the better the pancake.

Now we all know how this bit goes. I decide to vary the inputs and see how utterly ridiculous the formula becomes. First let's start with the units. So far as I can tell we have units of "lumps + consistency^2 + Temperature^2)/time". It's a long time since I did any dimensional analysis, but I don't think this is a dimensionless parameter.

Second, let's see what happens if we increase S. In fact, let's increase S a lot, let's leave the batter to stand for, say, 2 million years before we cook it. Then (assuming that the units make some sort of sense) it doesn't matter how bad we get our consistency, or how many lumps we have, it's going to be damn-near perfect. (Anything divided by 2 million years is pretty small).

Now let's see what happens if we let S and e be really close together. Say we let the pancake batter stand for a minute before we cook it, and then eat the pancakes a minute after we have cooked them. Well then, unfortunately, our (S-e) term goes rapidly towards infinity, and it doesn't matter how perfect our consistency was, or how hot the pan - the pancakes are going to be terrible.

We'll skip over the question of what "flipping score" is supposed to mean, and resist the urge to make the obvious play on words...

Finally let's consider those consistency and temperature terms. They are, remember: C(k - C) and T(m - T) where C and T are actual temperature and consistency and k and m are ideal temperature and consistency (why the strange choice of letters I have no idea. Now, depending on the value of (10L-7F), we are either trying to maximise or minimise these terms. If we are maximising them, a little calculus shows that we want to choose C = k/2 and T= m/2. So then we don't actually want to set the pan to the ideal temperature, we want half of the ideal temperature.

But we're probably minimising them (that seems to make more sense.. although why that should affect anything to do with this formula I have no idea). Then we want to choose either T to be one of 0 and m and C to be one of k and M (of course, as these functions are continuous, T arbitarily close to zero will give arbitrarily close to the minimum value. So the optimal temperature for cooking pancakes is either the ideal temperature or zero. And the optimal consistency is either the ideal consistency or zero... remind me again what ideal meant?

Of course, there's no reason why that term we subtract from 100 should be positive. If you're damn good at flipping pancakes, (F is very high) then you might be wanting to minimise those temperature and consistency terms, in order to stop the whole lot being 'too negative'.

Of course, this is all nonsense. I haven't even gone into how one is supposed to give a numerical value to 'consistency' and 'lumps', or the fact that we're not even told what units we're measuring temperature in. It's poppycock, and balderdash. No wonder people think scientists waste all their time doing pointless things when some idiots are willing to put their name to a formula like this. It doesn't help anyone, it's completely uneducational, and it just adds to the idea that maths is something complicated and useless.

I don't know who Ruth Fairclough teaches at the University of Wolverhampton, but I bet she doesn't let them get away with sloppiness on this level in their coursework.

Addendum: Just noticed this excellent post, which makes much the same points as I did, but has a much prettier layout...

Enforced Quackery: Day 7

So, I wondered how long it would be, and it seems the answer is "about 6 weeks". The question? 'How long is it possible to be taught by homeopaths without hearing some nonsense about quantum mechanics?"

Day 7 consisted of a visit to the London Homeopathic Hospital. Just for added irritation value, this is on Great Ormond Street, and one has to (I am reliably informed) walk past the famous hospital where they actually do real medicine in order to get there. There was a meeting with a GP who is also a homeopath. He seemed to be the most sensible of the pracitioners they'd come into contact with so far - coming pretty close to Ben Goldacre's ideal of "ethical bullshit". He gives homeopathic remedies to patients because they seem to help, and doesn't worry about why - he was quite willing to admit that the mechanism is very probably the same mechanism as a placebo... but he made the fairly valid point - if I can give these people pills that make them feel better, why not do it? And who cares how they work?


Of course, then he was asked about how he thinks they work... while admitting that a placebo effect was a possibility, he then spouted the traditional nonsense about what he thought the mechanism might actually be, invoking the "memory of water", and something called "non-linear quantum mechanics". Now, I'm no expert, but I distinctly remember reading something about non-linear quantum mechanics fairly recently, it was this paper which no-one who isn't studying Complexity Theory should bother reading. It says that if quantum physics is non-linear, this should in theory allow us to build quantum computers which solve NP (and even #P) problems in polynomial time. It also says:

Such non-linearity is highly hypothetical: all known experiments confirm the linearity of quantum physics to a high degree of accuracy.

That's right the explanation for the extremely macro-level phenomenon of really really tiny water molecules somehow managing to remember that they once came into contact with significantly less tiny arnica molecules has something to do with the fact that the superposition principle of quantum mechanics - which has to do with things which are a lot tinier than water molecules, might possibly be violated in some cases (even though no-one has ever actually seen this happen).

This is classic bullshit. Essentially the argument goes: homeopathy works, and we don't really know why. I don't really know how quantum mechanics works either, so surely it must have something to do with that. It's not science, and it's certainly not an important part of a medical education.

Once again, there were complaints made to the people in charge about the fact that there hasn't been nearly enough patient contact (although apparently they did see a few during this session). Once again, the reason given was that the "medical practitioners" were worried about what the future doctors might say to their "patients". Again, a promising sign that they've not been brainwashed, but surely if they're not going to be allowed to see patients, then they're not going to be able to observe Medicine in Society.

Enforced Quackery: Day 5

Day 5 consisted mostly in a visit from a herbalist. Well, I say a herbalist, she seems mostly to have worked in Marketing for A Vogel - the "educational" material from this session consists of no less than 9 advertising leaflets from that company along with three or four studies which find that herbal medicine is just as effective as conventional medicine at treating certain illnesses (more cherrypicking? I don't know - maybe these medicines actually are as effective as the artificial counterparts). I would post links to the leaflets, but I can't seem to find them online, and I'm not sure I really want to give them even more free advertising. They were also given a free sample of one of the products (I think it was Echinacea throat spray).

Now, I am not a medical student, and my girlfriend has only been one for just over a year, but we're both pretty sure that it is not standard practice to invite representatives from drug companies to give a brief talk to students about how awesome their company's products are (if it is, we're pretty sure it shouldn't be). And can only imagine the reaction from the Alt. Med community if it were widely reported that Big Pharma had been having friendly one-to-ones with students in which it passed out free samples of it's products, and leaflets explaining how ibuprofen was way better than arnica for treating a sore ankle.

Anyway - the other thing to come out of day five was more details about the assessment for the module. There will be an essay on the case study from day 4, and my girlfriend has also chosen to write an essay on "The role of homeopathic medicine in the health service" (or some very similar title - it might be the role of homeopathic medicine in society, which I guess is slightly more pallatable). If anyone's still reading this, she'd be very grateful for suggestions on how it might be possible to write an essay about that, to be marked by a homeopath, without being intellectually dishonest.

Day 6 was today - I'll post something about that as soon as I've spoken to her.
