Pancake Day

This coming Tuesday, the 16th February, is Pancake Day here in the UK.
Officially this day is Shrove Tuesday, the day before Ash Wednesday which is the first day of the season of Lent. The word shrove comes from the old English word shrive, which means to obtain forgiveness of sins by confession and penance. On a lighter note, Shrove Tuesday was also the last opportunity for a feast involving things like sugar, flour and eggs which were often given up for lent and therefore needed using up. If you put those ingredients together and add a bit of righteous haste, you get pancakes!
We celebrate this edible family tradition every year without fail, and if you'd like to partake too but are 'culinarily challenged', here's all you need:

• 100g plain flour
• 2 eggs
• 300ml milk
• 1 tablespoon vegetable or sunflower oil
• pinch of salt

Put the flour and pinch of salt into a large bowl and mix well. Crack the eggs into the middle and add about 50ml milk and the spoon of oil. Start whisking from the centre, gradually drawing the flour into the soggy bits until you have a smooth, thick paste. Now, while still whisking steadily, pour in the rest of the milk until you have a batter just thick enough to coat the back of a spoon.
Add a little vegetable oil to a fying pan and heat until hot. This is a key; for good pancakes the oil needs to be so hot it is just beginning to smoke. So open a window then pour some batter into the pan, tilting the pan around so it gets filled by a thin, even layer. Cook this for about 30 seconds or until the bottom is golden brown, then flip and cook the other side. Take the pancake out onto a warmed plate (keep it flat, don't fold) and cover to keep warm. Repeat with the rest of the batter, occasionally adding a little more oil to the pan as required.

Great! Now you've got your pancakes the next question, of course, is how to eat them. Basically you need to coat the pancake with a dollop of something nice then fold it or roll it up. Here are some variants:

• Tate & Lyle's Golden Syrup - Sorry if you can't buy this overseas; it's a British thing. Its a thick, thick, golden liquid that sticks to your spoon and is sweeter than anything could ever be.
• Honey - Not bad; give it a try. The runny sort is easier to work with.
• Maple Syrup - A sweet American import. Just pour it on.
• Mincemeat and squirty cream - Another British thing; this is not minced meat; it's the heavy concoction of preserved fruits you get in minced pies and Christmas puddings. Use a spoonful straight from the jar and let the kids enjoy adding their own aerosol cream.
• Pie fillings - The fruit kind you get in tins. Just drop in a spoonful and maybe add some squirty cream or sugar.
• Chocolate spread - Personally I think this is going too far, but each to his own.
• Fresh fruit - Thinly sliced strawberries, with a sprinkling of sugar or a hint of cream, are very good.
• Ice cream - Use a soft type, don't add too much and eat quickly.

My personal favourite though, and the one I always go back to, is also the simplest. Just drizzle the pancake with lemon juice, sprinkle on a good helping of sugar, roll, and enjoy.
Have a great pancake day! And let me know how you ate yours.

A Snowball's Chance

Ah, I do love quantum physics. It's the strange scientific realm where everything is possible - and I do mean everything.
In the 'real world', if a ball bounces off a solid object or another ball, even if both of them are moving, we can say with certainty what will happen. Observe this same collision ten thousand times and every time the result will be the same - which is just as well if you're trying to learn how to play squash or pocket the eight-ball in pool.
Scale things down to the quantum level, however, and strange things start to happen. If we watch two particles colliding, for example, the outcome according to quantum physics becomes anything but certain and the predictability of conventional Newtonian science lets us down. Not only do things happen that we would expect to see happening, but things we wouldn't expect also happen, and occasionally things take place that seem completely impossible. In real-world terms, it would be like throwing a snowball at someone but having it turn aside in mid-air and miss the target. Or, even more bizarrely, flying straight back to smack you in the face.
Sounds insane, doesn't it? But these aren't the deranged ramblings of a mad theorist who ate too much cheese before settling down for the night; these are real, measurable effects.
At the quantum level of matter every outcome is possible, even the impossible ones, and if you watch for long enough you will see them actually happen. Thus it becomes impossible for us to say that in a given situation a particular outcome will occur; all we can do is quote the probability, or chance, of each concievable (and inconcievable) result.
This kind of thinking is weird and uncomfortable, so weird that even Einstein didn't like it and made his now famous assertion that "God does not play dice". Developments since then have shown, however, that God really does play dice - and He's very good at it.
One of the 'shouldn't-ever-happen-but-sometimes-does' effects that occur at the quantum level is really strange. To use a real-world example again, if we saw a car being driven at speed toward a solid wall what we'd expect would be a loud bang followed by the tinkle of falling glass and the quiet hiss of escaping steam. What we definitely wouldn't expect is for the car to pass through the wall as if it simply wasn't there and continue on it's way totally unaffected. Quantum particles do this sometimes; it's called tunneling. If moving particles hit a barrier, most of them get stopped but some pass straight through it, like the girl in the X-Men films who can walk through solid walls. It sounds quite insane, but it's an observable effect and it's coming to a smartphone near you.
This wierdness is harnessed in a material called QTC (Quantum Tunelling Composite) recently invented by a Yorkshire-based company and already licensed by two Japanese corporations that make components, particularly touch screens, for mobile phones and other portable devices. Embedded within the material are conductive nanoparticles which, if they were in contact, would allow the material to conduct electricity. It doesn't, however, because the particles are slightly separated - except for the tiny current that flows anyway because some of the electrons quantum-tunnel through the insulation that surrounds them. Compressing the material forces the conductive particles closer together, this increases the probability that tunneling will occur and so the current rises.
What does this give us? Pressure sensitive material!
Think of a touch screen that responds not only to the speed of the finger swiped across it but also to how hard the finger presses and how that pressure varies throughout the stroke. It would make the best of today's touch-screen devices seem as clumsy as a mechanical keyboard. Imagine also placing that material on the surface of a mechanical hand and giving it what we humans take for granted - touch sensitive skin. A robot with a hand like that would be able to sense how much pressure it was applying with it's fingers and adjust accordingly - enter the gentle robot surgeon, the kitchen helper that can hold an egg without crushing it, or the prosthetic that allows the wearer not just to move but also to feel. That's a massive improvement over a simple motorised claw, and it's all thanks to quantum physics.
Regular readers will be wondering if there's a spiritual angle to all this. Well, sometimes we humans gain a little knowledge and then become arrogant, strutting intellectually around God's universe like we own the place and telling him how He should behave. That's when God lets us discover something like quantum physics to show us that there's far more to Him and to the hidden mysteries He's created than we're ever likely to understand. As the book of Ecclesiastes so neatly puts it, "God is in Heaven and you are on the earth. Therefore let your words be few."
The Bible states, and quantum physics confirms, that "With God, nothing is impossible." So be careful next time you decide to throw a snowball, because if there's one thing that quantum physics shows us above all else, it's that God has a really mischievous sense of humour.

The Foam Strikes Back

A while ago I promised you an update on my experiences with the memory foam pillow. I know it's been a while, but I wanted to make very sure I was happy before I came back with an endorsement.
I'm still sleeping better and glad to find I'm not permanently tired like I used to be. Sleep is certainly an under-rated activity and something we probably all should be doing more of. But in my case it wasn't so much the quantity of sleep as the quality of it; I could sleep for ten hours and still wake up shattered, which was no good at all. The new pillow is helping, though.
I'm also glad to report that so far the pillow hasn't developed a head-shaped cavity. It has, though, become a little softer and more willing to mould - perhaps an indication that memory foam gets better with age and that you have to persevere to get the best from it.
All in all, then, the foam pillow has got to be the best forty quid I've ever spent, and if it ever becomes unserviceable I'll be getting another to replace it.
Hmm. I wonder what memory foam matresses are like?

Have Your Say?

So, Gordon Brown is suddenly anxious to make sure that we, the great British people, have the chance of a referendum on his proposed changes to the voting system.
That's nice.
Pity about all the other critical referenda that he and his Government carefully avoided giving us. There's the Lisbon Treaty (in violation of a manifesto promise), the war in Iraq, the identity card proposals and the question of whether expense-fiddling MPs should be thrown into the town stocks and pelted with rotting fruit to name just a few.
Let's face it - none of the current crop of politicians want to risk a possible public veto. They'd rather hide behind their election mandate and implement their ideology for five years regardless of what anybody thinks.
Yes, our political system does need to change. But not by tinkering with it so a bunch of ploiticians who know they're doomed can climb back onto the gravy train that much sooner. The change we really need is for politicians of all colours to realise their high office is a position of accountability and trust and that they are there not to build a career or make money but to serve those that elected them.
