# Cool H+ type video

Not only do I love VNV Nation, but I thought that this fan-video is really excellent, and quite inspirational from a H+ point of view.

Thanks to Dirk for pointing this one out 🙂

# It’s just too cool to be a scientist these days.

Via Pharyngula:

I was thinking after the LHC rap that a QC rap video would be cool to do, but I don’t think anything I could do could possibly match the standards set by the Australian Commonwealth Scientific and Industrial Research Organization (CSIRO):

I also now want a giant gold medallion with a $\Psi$ on it…

OK, this may be even cooler than the violation of Bell’s inequalities in Phase qubits.

“The sky calls to us
If we do not destroy ourselves
We will one day venture to the stars”

Almost makes me cry… Here’s to the amazing Carl Sagan.

# Woo-rant: Mystics invade my Sunday morning

I spent some of my Sunday morning watching a program called ‘The big questions’. This is usually fairly good, they invite a general audience and some people considered knowledgeable in their field of speciality, and debate political issues. This week one of the questions was about ‘Life after Death’.

When I first heard the premise of the show, I thought that there would be at least one clued up scientist debunking the myriad of mediums, pentecostal ministers and downright crazy people making up stories about receiving personal visitations from their closely departed friends with tales of how pleasant the afterlife is. Alas, I was sadly mistaken. In fact, the only guy on the program who had any scientific background made the whole thing WORSE by completely fumbling his description of what is currently understood in the field of neuroscience and reducing it to ‘we really don’t understand at all how the brain works’ – wrong – ‘but we understand how vision works, for example, and if you remove a person’s eyes they cannot see, therefore how can they claim to have seen things after death’? – this was a.) irrelevant and b.) incorrect. The brain can simulate the experience of vision through memory prediction, (think about for example when you ‘see’ in a dream). It can also link other sensory inputs with predicted visual input (e.g. identifying objects whilst wearing a blindfold allows you to ‘imagine’ how the object looks).

Having just read Jeff Hawkins’ On Intelligence (thank you Geordie for recommending that one), the counter-arguments to a rational, physical theory of intelligence seem all the more strange. This book puts forward a beautiful computational model of the brain, which explains how intelligence can arise, why humans are so much better at certain tasks than computers, and also explains the hiaracy of intelligence in animals in terms of this model.

Indeed, after reading this book, I have now become even more of a Strong AI supporter.

How can people not acknowledge that the brain could be explained by a beautiful theory, instead wishing to attribute some ‘mystical’ connotations to it? Why does someone not having the wish to understand how something works give them the right to argue that no-one will ever have the capability of doing so? Why do their mystic arguments hold any water at all?

Because it’s easier to resign yourself to some fuzzy, warm, but completely incorrect way of thinking than to actually work damn hard towards the real understanding. And this laziness perpetuates itself.

Of course, people can resign themselves to this if they so wish, but they should not be allowed to preach it on live television as though it’s a scientifically sound point of view: Just some equally viable ‘alternative’ to the best possible scientific enquiry with which people have been diligently pushing forward the boundary of understanding for centuries.

What a horrible, deepening blow to the scientific community to let the people who know the least appear as experts via this incredibly popular and trusted style of information dissemination. And it’s downright wrong to give the impression that the argument is stronger from the mystical side and that the science itself is weak, just because you invite more passionate and ‘knowledgeable’ *cringe* mystics than scientists themselves.

This all makes me slightly annoyed, but all the more determined to actually a.) understand the cutting edge research in this field so I can b.) disseminate it correctly to these people.

To top off the woo-week, I watched What the Bleep Do We Know!? – Basically because I’d heard from the physics blogosphere that it was really, really awful. And hail! The physics blogosphere was correct 🙂 I would still highly recommend the film to anyone who works in QM or even Physics/Biology in general, because we should be aware that stuff like this is not only in circulation, but is actually believed to be factual by many people. Maybe we should make a sequel: What the Bleep Do We Know!?: Quite a lot actually, if you ask reputable scientific people… Subtitle: – And don’t edit their responses to favour your own warped point of view –

I also felt that the copy of the film was better off in the relatively safe quarantine of my woo-antivirus vault (aka DVD shelf) than publically accessible (I found it in HMV). I did however feel slightly wrong after actually paying for a copy :S

One thing I did actually quite like about the film were the Dr. Quantum animations, I think they were very visually appealing. They would be a great way to enhance the teaching of (correct) science to kids, and indeed to interested people of all ages.

OK, end of PZMyers-esque-ness 🙂

# Fusion power and climate change

I’m really confident someone will have fusion technology working pretty soon. There are so many people now getting interested in this area. Just in the past few weeks I’ve found this article covering progress at General Fusion, and this follow up article from Next Big Future. There’s also this article about progress with Polywell-style reactors, and that’s just what’s popped up in my newsfeeds, I wasn’t even looking 🙂

Speaking of cleaner energy, this story was all over the main news channel yesterday, discussing climate change in the UK in 60-70 years time. What? Why do people insist on extrapolating current trends without even considering technological advancements (exponential ones at that)? I can’t believe that people have such a pessimistic doom and gloom attitude towards this issue. They should be running news stories about research and progress towards future methods of active, local and global climate control and advances in green technologies. I seriously believe that by 2080 we’ll be thinking it was rather quaint that people were so worried about the fate of the planet from the point of view of traditional, naturally occurring weather systems. And our ability to produce large amounts of CO2 detrimental to our own survival will be more likely seen as a bygone era once we are able to control the global climatic conditions.

I do still believe we should make what changes we can now to reduce further compunding of the energy crisis. Hence why I’m saving up for a hybrid car. But think about the probability that someone, somewhere will engineer and commercialize (Note: not even invent – there are plenty of good ideas already) a green energy technology which can be implemented globally within the next 50 years. I don’t think that seems unlikely. I get really irritated with the large proportion of technologically traditionalist and Luddite views in this country, especially when they dominate news headlines!

# Quantum computing fail…again.

Courtesy of Quantum Bayesian Networks, an article entitled “The Quantum Leap of Quantum Computing” on Penny Sleuth. It’s great to see a wider business and market audience becoming interested in QC.

However, this is slightly irritating:

“This means computers would become exponentially more powerful because each “quantum bit” (qubit) could store a much greater range of numbers than the two that binary math restricts us to. Imagine a laptop with the computing power of the world’s 10 most powerful supercomputers. Then you begin to grasp the potential of quantum computing.”

In the spirit of a very popular television program:

Let me explain for any readers who are slightly confused at this point: Quantum computers will be very good at solving certain types of hard problems somewhat faster than classical computers. This should become some sort of mantra. (If anyone can think of a catchy version that would be cool).

They won’t be general purpose machines. The best way to think of a QC is more like a co-processor (say like a hardware graphics accelerator).

The types of problems that they will be good at solving are exciting and interesting in themselves. Quantum computers are cool enough without the overhype 🙂

# An Inconvenient Truth

I’ve recently watched the film AN INCONVENIENT TRUTH, directed by Davis Guggenheim, featuring Al Gore.

I’d highly recommend watching this film. I found it really moving. Here is the Wikipedia entry for the film, including quite a few opinions from film critics. Trying to normalise away any potential political spin here, Al Gore seems like a nice guy who actually cares. And indeed one who knows his stuff.

A few film critics accuse the movie of skewing the data, however I’ve attended several seminars on climate change recently, and the results reported in those seem to agree with what was presented in the film. They all seem to paint a similar picture.

‘Nine errors’ have been pointed out in the film, points used for impact which are unsupported by current scientific studies. This news report gives a good summary. The film is allowed to be shown in schools as long as ‘guidelines’ documenting and explaining these errors are included.

The film gives some useful information and tips at the end, and believe me even if you *think* you’re being green, you could probably improve on it tenfold. The film has seriously made me consider buying a hybrid car.

On a slightly unrelated note, the film also demonstrates how to essentially make a movie out of a seminar consisting of a slide-show presentation. It works really well and keeps the audience attentive. I think this is generally a good way of presenting physics/scientific ideas.
