Derren Brown may not have predicted the lottery, but I predicted his bullshit

Sep 11th, 2009

Oh dear.

It was obvious from the start that Derren Brown wouldn’t predict the lottery, and the failure to reveal the balls before the draw just made the whole situation blindingly obvious. As soon as he did that, the whole situation boiled down to little more than a glorified card trick.

Now, I’ll be first to admit I don’t know how he did it. That’s not any indication that the trick was difficult, but rather the fact it was so sodding easy. While Paul Daniels claims that he knew 99 ways of achieving it was probably a slight exaggeration,  several possible solutions occurred to me both during and following the show. Personally I favour the ‘split screen’ argument, having used a similar technique myself I know how trivially easy such things are. (Even if I was thwarted by an ill-placed mirror)

The split screen idea is also supported by movements seen within the balls as the results are read out, although a similar effect could also have been seen with other suggestions, such as those of a mechanical ball printer. Other possibilities include an augmented reality approach, digitally projecting the numbers onto the balls, although if such an effect had been achieved, it was remarkably effective.

The general point being however that there are a number of ways the trick could have been achieved, not even taking into consideration sleight of hand, which admittedly would have been difficult if we are to assume that the camera feed was genuine. No prediction, or fixing, was required.

Now originally I dismissed simple camera trickery, it seemed too much of a cheat, and seemed unlikely to take up a whole hour show. Then again, I couldn’t see how any plausible explanation could take a few minutes; therefore Brown was going to bullshit us. The trick and misdirection would continue into the explanation, as Derren led us on a merry goose chase. Unfortunately it appears that I only bothered to tweet this at the beginning of today’s show, which is still a darnsight better than Brown’s after the fact ‘prediction.’

It was obvious from the start that Derren was aiming to misdirect, firstly by implying that there was any psychology involved, and then by progressively misleading bouts of mathematics.  While I wouldn’t go so far as to suggest that the lottery is truly random (such as some quantum events appear to be) any biases are going to be so minor, and external factors far more significant that any attempt at prediction will be impossible. To imply that crowd-sourcing would be ow any use in determining a random set of numbers is entirely misleading.

Which brings us from the impossible, to the improbable. The fixing. I don’t know if Derren hoped to convince his sceptic audience with this spiel, but we are fed a series of unlikely events which would be both illegal and unethical. While people indeed commit illegal and unethical deeds, they rarely do so publicly on national television.  Furthermore, to suspect that Camelot’s security is lack enough that a breach made in August could subvert a draw made in September is laughable.  Furthermore, there are 14 sets of balls, so I find it hard to imagine that this was the first time one of the alleged six was used since the claimed breach. Not to mention, I’m far from convinced that a 20g difference would be sufficient to entirely bias the draw.

While I’ve happily excluded the impossible maths explanation, leaving the improbable fix explanation, I’m sadly still left with a considerable set of downright more probable explanations. Had Derren’s numbers been revealed before the draw, then things would be different, and I’d probably be checking into exactly how long the broadcast delay is from lottery HQ. However just because Derren has given an answer, doesn’t mean I’m going to believe it.

Unfortunately Brown’s attempts at an explanation did little to endear me to him during the show, despite the fact I’m usually a fan. The fact he was spouting nonsense was obvious, which made me hope more and more for a strong pay-off. Derren Brown likes to market himself as a sceptic, and thus I hoped he’d build up to a clear crescendo, which illustrated his audience had been duped.  Parallels between the earlier practice ‘draws’ and the final draw (mainly that the result was revealed after the draw) made me hope that these factors would tie themselves into the great reveal, that we’d get a clear mention of why two camera-men were present when only one was necessary. Instead though we got yet another, albeit a marginally more plausible, shaggy dog story. Not only do I feel that Derren Brown did not reveal his trick, but he ultimately failed to demonstrate anything in the hour long show. Only in his last words, “I’ll tell them it was just a trick” did he bother to give any nod to the truth, a matter which probably passed by anyone who wasn’t already sceptical.

Ultimately I was disappointed with not only the trick itself, but with the explanation, which demonstrated little more than Derren’s ability to string people along.

Bean had?

Jun 9th, 2009

You may have noticed reports in several newspapers and tech sites today of the Heinz Beanzawave, a USB powered microwave. In total, according to Google News, the story appears to have been covered by over fifty different outlets including the UPI, CrunchGear, Cnet and the Daily Mail. Not to mention a number of popular blogs, such as BoingBoing. While some of these articles have users raising criticisms in the comments, none of the news sources I checked bothered to run a critical eye over the story. (If you find one, please post it in the comments so the good guys can get some acknowledgements.)

The news seemingly originated from a press-release form the ‘Microwave Association,’ working in association with Heinz. Unfortunately for fans of beans and fancy USB gadgets the story appears to be, well, a load of old beans1.

Even a quick critical eye will spot some key flaws. The average modern microwave has an output of 850W, with even weaker models outputting at least 650W. By comparison, the USB 2.0 standard provides a maximum current of 500mA, at 5V; which works out as a maximum power output of just 2.5W2. The former figures should be familiar to anyone who has cooked something in the microwave, as the output is printed on the front, and you are expected to adjust cooking times accordingly. The latter meanwhile should be obvious in part to anyone who has hooked up a printer. While simple devices like mice can obtain sufficient power from a USB socket, the same can’t be said for more power-hungry devices such as printers, which need their own power supplies. Indeed, the power supply units of most computers aren’t certified to deliver 850W of power, with possibly only high quality gaming rigs fitted with a hefty enough PSU; even then, powering a microwave would leave scant remainder for the processor and graphics card.

So we’ve already seen that such a device would have to operate at a significantly lower power output than most modern microwaves. Such a device would be unlikely to be marketed as a novelty, and instead would be positioned to replace most standard microwaves. However is it possible that such improvements have been made, and we are in fact looking at vastly superior technology. In short, not likely, unless they have also managed to break the laws of thermodynamics in creating this miracle microwave.

In demonstrating how truly impossible their claims are we need to consider some physics.

The specific heat capacity of a substance is used to describe how much energy is required to raise its temperature; for water, this is given as approximately 4.2 joules per gram per kelvin. This means that for every gram of water, you must supply 4.2 joules of energy, to raise the temperature by 1 kelvin, or 1 degree Celcius3. Therefore, for a 200g tub of beans (which we shall approximate by assuming it is all water.) it takes 4.2 x 200 = 840 joules to raise the temperature by a single degree.

So how does this translate to our microwave? Well fortunately, the measurement watts tells us how many joules of energy are transferred each second. In other words 1 watt = 1 joule per second. So if we are to assume that our microwave is 100% efficient, that all energy it uses goes directly into heating the beans, we can discover how long it will take to deliver the required 840((And here is a good illustration of the inefficiency of standard microwaves. As by this calculation the beans should be ready in just under a second.)) joules to raise the temperature of the beans by a single degree. Simply divide 840 by 2.5 and… oh dear… 336 seconds. Five minutes, 36 seconds to warm the beans by a single degree. If you want them boiling hot4, then you are going to be waiting over 7 hours.

What bothers me most about this story isn’t the dubious nature of the original press-release. It was clearly constructed by marketing bods in an attempt to gain free column inches. In that respect it worked, and I’m only adding to the effect by writing this. What bothers me is the way the press regurgitated it, unthinkingly, unquestioningly, delivering advertisements as news. Not only this, but it is clear that in most cases, they didn’t even stop to pass a critical eye over it. This isn’t just churnalism, this is factually incorrect churnalism. When the media sacrifices its credibility in terms of fact checking, and ends up falling slave to marketing, what does it have left? And when we lose one of the key methods of fact distribution, of investigation and exposure, what do we have left? Blogs and citizen journalism go so far, but an effective and trustworthy media is is important for everyone; this story is only one of many that makes me wonder how much of one we have left.

I have already contacted the Microwave Association in the E-mail provided in the press-release, and have invited them to respond. I’ll update this entry as soon if I hear anything from them, and leave the comments open if they wish to contribute there. (Although I encourage you do do so via my E-mail, as that way I can be sure the response is genuine. Also, please bear in mind that comments from new users will be held for moderation, and may not get published immediately.)

  3. The scale of Celcius and kelvin is identical. Only the position of the zero position changes, with 0 kelvin being equal to -273.15 °C []

Not in my name

Jun 9th, 2009

Sixty-five years ago 160,000 troops landed on the beaches of Normandy to drive back the forces of fascism, and to protect the freedoms that they held to be important. Thousands of others worked behind the scenes to provide the ships necessary to co-ordinate such an astonishing feat, not to mention those involved in the concurrent air assault.

On Sunday, the UK elected two members of the British National Party to the European parliament.

Already, many words have been written by people vastly more knowledgeable and articulate than me. Members of both the left and right have expressed the disappointment, anger, and sorrow at such an event. On Monday, and late Sunday, Twitter swarmed with people discussing the result and its implications, and for most of the day BNP was the top trending topic, with many other related terms putting in an appearance further down the list. Blogger Anton Vowl considered how some of the failures of New Labour led to this situation, not through any particular success of the BNP but through the apathy of other voters. Others, in their frustration, threw eggs.

I shall not be re-hashing these arguments. They are elsewhere and the points have been made. I shan’t be throwing any eggs, our position against the BNP is stronger than that; we don’t want to re-enforce their delusions of martyrdom. I will however say this: The BNP don’t speak for me. They claim they represent average Britions; I’m British, they don’t represent me. They claim they wish to make Britain great, but in doing so attempt to destroy the things I love about this country. We are better than this. The BNP may talk of “stemming and reversing the tide of non-white immigration” but they do not do so in my name. hnh

Anti-racism and fascism organisation, ‘Hope Not Hate’ is collecting signatures1 to deliver to the European parliament to show that the BNP do not speak for all British people. If you feel that the BNP do not speak for you, and wish to make your feelings known you can find the petition here.

  1. I sign this out of my own moral revulsions that I have become associated with these people by virtue of nationality. The petition is not an attempt to overturn the democratic process. []

Weddings

May 26th, 2009

On Saturday I attended my first wedding of the year. The weather was absolutely gorgeous, and the whole thing went off seemingly without a hitch to the various guests assembled. Well, apart from the bride’s car breaking down, but what would life be if it couldn’t mimic a sitcom every once in a while. But in short, everyone was in a great mood, and the whole thing proceeded with a genuine sense of warmth, which was down to more than just the weather.
The fact that the happy couple were tying the knot wouldn’t come across as a surprised to anyone there. They had been together for many years already, and to anyone who knew them their marriage had become a matter of when, not if. Two people recognising and celebrating the fact that they love each other, what else could be more deserving of celebration?

You’d think so anyway wouldn’t you? Except for some people, a change of one small detail, one which I have in fact neglected to even mention in full, would change the above situation from something which should be celebrated, to something which should be prevented.

Today the Californian Supreme court voted to uphold Proposition 8, a dark stain which had made Obama’s victory in November, somewhat bitter-sweet. For the 52% of Californian voters who gave their support to the legislation, gender is far more important than love when it comes to marriage. Seemingly “Life, liberty, and the pursuit of happiness,” bears a footnote ensuring that it is somewhat tempered if you happen to love someone with the same genitals as you.

“The freedom to marry has long been recognized as one of the vital personal rights essential to the orderly pursuit of happiness by free men.”
-Earl Warren 1891-1974
Governor of California 1943-1953,
Chief Justice of the United States 1953-1969

Of course, America has been through this all before, albeit in a slightly different guise. It has been 42 years since Earl Warren, a Californian, overturned Virginia’s Racial Integrity Act, and ended race based restrictions on marriage throughout the US. I’ve borrowed a quote from him, which is as valid now as it was then, and I hope that he’d approve of its usage in this context, even if it would distance him from 52% of voters in his state, and countless members of his Republican party.

Charlie Brooker to do Gameswipe?

May 6th, 2009

Its looking likely! Earlier today, newspaper columnist, television presenter and all-round misanthropist Charlie Brooker gave hints that we mad soon be seeing a series of ‘Gameswipe.’ In a tweet on his @charltonbrooker Twitter account, Brooker asked for the following:

Worst videogame bosses ever? Email yr suggestions to gameswipe at zeppotron dot com. Make what you will of that email address.
10 minutes ago from TweetDeck

Brooker is no stranger to games journalism, as his career began back on the pages of PC Zone. He has also regularly mentioned various computer and video games in his column in the Guardian. The E-mail address also appears to be associated with Zeppotron, the production company behind both Newswipe and Screenwipe.
Brooker’s recent satirical and biting look at news coverage in the form of Newswipe was absolutely fantastic, both hugely entertaining, and damning in its criticism, proving to be one of the only television programs for which I will bother setting an alarm.
Exactly how the *wipe format will be adapted to gaming is unclear, as both Newswipe and Screenwipe focused heavily on the past week or so in television/news, an approach which is unlikely be be so suitable for the slightly slower moving world of gaming. Thus its possible that we shall be looking at a one off special episode, or a short series taking a more general look at gaming; certainly the E-mail request somewhat suggests the latter.

Edit: Wow! I should post breaking news more often, this post is only twenty minutes old, and its already brought in a load of visitors.
