The Perfect Mathematician

Think I’ve stumbled upon what is fundamentally wrong with UK STEM policy, at least for the Maths bit.  We’re not raising mathematicians correctly.

In ‘The First Men in the Moon‘, H.G. Wells shares with us how the Selenite moon people got it right – over a century ago:

“If, for example, a Selenite is destined to be a mathematician, his teachers and trainers set out at once to that end. They check any incipient disposition to other pursuits, they encourage his mathematical bias with a perfect psychological skill.  His brain grows, or at least the mathematical faculties of his brain grow, and the rest of him only so much as is necessary to sustain this essential part of him. At last, save for rest and food, his one delight lies in the exercise and display of his faculty, his one interest in its application, his sole society with other specialists in his own line. His brain grows continually larger, at least so far as the portions engaging in mathematics are concerned; they bulge ever larger and seem to suck all life and vigour from the rest of his frame. His limbs shrivel, his heart and digestive organs diminish, his insect face is hidden under its bulging contours. His voice becomes a mere stridulation for the stating of formula; he seems deaf to all but properly enunciated problems. The faculty of laughter, save for the sudden discovery of some paradox, is lost to him; his deepest emotion is the evolution of a novel computation.  And so he attains his end.”

Appearances Can Be Deceptive

I keep running into this demonstration of how strange our brains can be, so thought I’d have a go myself.

Have a look at the inverted face below.  Upside down, but still pretty cute eh?

Cute
Cute

Now look at the next picture where she’s turned the right way round – yuk!

But it’s exactly the same picture just inverted.  Our brains somehow pick out the individual elements of the face and reconstruct them as we normally expect to see them – I guess?   Personally, I can’t see a glum person in the top picture without turning my head to a degree – I’ve just discovered – not so good for my neck.

Not so cute.  Well, not so happy anyhow.
Not so cute. Well, not so happy anyhow.

This simple example was made by cutting, rotating, and pasting the mouth of the girl in the painting.

I saw something like this a couple of years back at the Exploratorium Science Centre in San Francisco.    The most recent demonstration I’ve seen was at the Weird Science event here in London earlier this month, where Richard Wiseman had us all in hysterics with a doctored picture of Margaret Thatcher.  That was doubly strange, as: (a) he’d turned the eyes round as well (which is the correct thing to do, but my painting struggles because of the hair) and, (b) rotated the image slowly, which revealed there is a certain point where the brain clicks over to seeing the ‘new’ image – the gestalt switch moment.

The Exploratorium exhibition also included so-called hybrid images of faces that change expression depending on how near or far you stand from them.  The effect still works very well on a computer screen, but you need to stand a long way back.

Not entirely sure how the brain processes compare for the two types of phenomena, but I find the ‘switch’ is more gradual with the hybrid images.   In deference to copyright I’ll not share the snaps I took, but you can find something very similar at the ‘Hybrid Images’ website owned by Dr.Aude Olivia, Dept. of Brain and Cognitive Sciences at MIT.

Heat Friends And Influence People

If you want to get close to someone, give them a nice hot cup of tea. Or anything warm for that matter.

Nice Hot Cuppa
Can't beat a nice hot Cuppa

New research suggests that when someone experiences physical warmth, they develop increased feelings of interpersonal warmth – and it all happens without them even knowing.

Tests by researchers at Yale University and the University of Colorado at Boulder showed that when given a hot cup to hold, a subject would judge another person to have a ‘warmer’ personality. In another test, application of a thermal pad resulted in the person tending to choose a gift for a friend rather than themselves.

The key to this behaviour is the discovery that a part of the brain, the insular cortex, looks after both the physical and psychological versions of warmth information, with feelings like trust, empathy, guilt and embarrassment also implicated.

So there you go – yet more evidence that we are completely out of control of ourselves. Ho Hum…..

P.S. Only use a Los Alamos mug if you are looking for that ‘extra warmth’.
