Fun facts (that aren’t even true)

Monday, May 31st, 2010 | Distractions, Science

Memes are incredible things. One good example I have noticed, is that there are quite a lot of fun facts that survive – despite not even being true, simply because they make a good story. Here are a few of my favourites…

You can see the Great Wall of China from space
Think about it. The United Kingdom is a dot from space, maybe a small blog at best. The city of Leeds is indistinguishable. It’s streets, rivers, buildings, Tesco Extras, all not even a speck. And you think you can see a wall four metres across? Didn’t think so 😀 .

The Americans spent millions developing a zero gravity pen. The Russians used a pencil.
This one is sort of true, but the Americans started out using pencils too. They just found they broke a lot and it’s irritating sharpening a pencil in zero gravity because the shavings go everywhere. It wasn’t like they just didn’t think to use a pencil.

If you put a frog in boiling water it will jump out, but if you heat it up slowly it will just slowly cook alive and won’t notice
Again, this is probably one of those that first makes sense but when you think about it is probably quite unlikely. To prove the point someone did it and found the opposite happens – if you heat the pot up slowly the frog soon jumps out when it gets too hot whereas if you throw it in a pan of boiling water it gets really badly scalded and dies.

On a hot day, it’s better to wearing white
This just isn’t true. This probably originates from the stereotypical image of Saudis wearing all white but many people in the Middle East wear black and are just fine. Actually there is no real evidence that light coloured clothes are any cooler in the warm weather than wearing all black.

Own brand painkillers are just as good as Nurofen
This might surprise the sceptics who read my blog, suprisingly. Actually research shows that Nurofen can often be more effective than own brand painkillers. Not because it is actually any better (they are exactly the same as own brand) but because a lot of people aren’t as sceptical as us and associate the fact that Nurofen has adverts on the telly box with medical efficacy. It is of course nothing more than a placebo effect but a measurable once none the less. Pat yourself on the back if you find the own brand ones just as effective because you know it’s the exact same ingredients – you’re one of us smart people.

In Australia, toilets swirl the other way round
It’s widely believed that when you flush a toilet in the Southern hemisphere it will swirl counter clockwise. But it doesn’t. The fact is the Coriolis effect simply isn’t strong enough to overpower other influences such as the way the drains are laid out, the way the jets are set up to go or even a draft in the bathroom.

Toffee tastes better when manufactured in high altitudes
I’ve tasted Lowland Toffee and it’s just as good.

Coca Cola made Santa Claus red
Smart people know that Santa Claus wasn’t always red. He used to dress in all kind of colours, often, green, until the Coca Cola Company re-branded him in red to fit with their advertising. Even smarter people know that actually, while the Coca Cola Company did go a long way to popularising Santa’s red outfit, the iconic modern image of Santa should really be credited to the American cartoonist Thomas Nast if anyone should receive the honour.

The death penalty still exists in the UK, but only for treason
This is something I hear from time to time although more people are becoming aware of it’s falsity. We actually did still have the death penalty in the UK until 1997 (not that it was ever used any more) but one of the first things New Labour did when coming to power was to see it out of law.

Re-examining Atkins

Tuesday, March 9th, 2010 | Science, Thoughts

One of the guys in my office has been doing the Atkins diet for a while now. This caused me to take a look at the research carried out on low-carbohydrate diets to see if there was any basis for the misery he is putting himself through.

Most people including myself just kind of wrote off the diet because the pseudo-scientific explanation behind it didn’t make much sense. However in 2004 the flagship BBC science documentary Horizon broadcast an episode showing it probably does work for reasons differing from those that Dr. Atkins actually claimed.

In fact, looking into the evidence for low-carbohydrate diets, while there is a huge mixed bag of results, the overall consensus seems to be that while more research is needed in the area, such diets are generally safe and are effective in weight loss.

Of course this isn’t to say that everyone should jump on Atkins. Diets are no replacement for basic healthy eating and well all know this. We’re all well aware the way to be healthy is to eat a balanced diet, treat yourself occasionally, hit all the major food groups and avoid eating prepared meals, fast food or generally anything that doesn’t require you to put some effort in preparing yourself, as much as possible. However, if you are going to diet, Atkins at least isn’t any worse than any other diet.

10:23 homeopathic protest

Sunday, January 31st, 2010 | Events, Humanism, Science

Yesterday saw a nationwide protest against the sale of homeopathic remedies at Boots. At cities across the UK, and indeed some in Australia and Canada too, people gathered to take a homeopathic overdose to show that there was in fact nothing in the pills at all.

At Leeds we managed to get 32 people down to the event most of which, including myself, downed an entire bottle of homeopathic arsenic and yet somehow survived. We also got a reporter from ITV’s Calendar news come down and featured us on their evening segment – I’ve yet to see it but I’ve heard a mixed reaction so far.

The response from Boots was a predictable one – homeopathy is recognised by the NHS (something which is in the process of changing as the government inquiry is quickly dismantling the case for it) and that many people use homeopathic remedies – of course many people read horoscopes that doesn’t mean there is any truth in them. But of course we knew they would just ignore the science and just try and insist that lots of people bought it so it must be true.

Most of the major papers have run stories about it today so we’re chalking this one down as a big success for the skeptics movement. A big thank you to everyone from Leeds Skeptics who came down to take part, Daryl for organising the Leeds event and the guys at Merseyside Skeptics for putting it all together.

Is sex necessary?

Tuesday, January 29th, 2008 | Science

I was Googling the spelling of necessary to make sure I had got it right when the top result of the search caught my eye. It was an article on Forbes entitled is sex necessary? It makes the case that sex is important in your overall health.

Benefits include a reduce risk of heart disease, weight loss, improved fitness, reduced depression and less frequent colds and flu.
