It seems quiet at first, and even dull. Not much happening… Dreich, as one might say! Sad. Grim. Bleak. Not much to do… Not much to see here… Just sheep… But wait!! Look closer! Is that Dolly in this field? Now, that’s interesting! Oh, Aye, we’re in Scotland! It changes EVERYTHING…

Do you know who your fourth cousins are? The chances are you don’t. But do you know who your friends are? Of course, you know that much. But did you ever stop and think why or how your friends are your friends? Could your friends actually share part of your DNA, to the same extent a distant family member does?

Earlier this month, UKube-1, a satellite built by Glasgow-based technology firm Clyde Space, successfully launched on a test flight from Baikonur, Kazakhstan. It is the first ever spacecraft to be fully assembled in Scotland.

What is the difference between heat and temperature? Heat is thermal energy. Temperature is a measurement of the average kinetic energy of the particles which compose the matter being tested. When heat flows into a material, one of two things happen: either the temperature of the material can rise, or there may be a change in its state (such as from ice to liquid, or liquid to vapour).

Today’s the 60th Anniversary of the Death of Alan Turing – a genial mathematician, a cryptographer and one of the pioneers of computer science at Bletchley Park. He is considered one of the greatest minds of the 20th Century. Alan Turing‘s life was one of complexity and secret triumphs, overshadowed by a very public tragedy.

Buoyancy is the upward force exerted by a fluid that opposes the weight of an object immersed in a particular substance. Essentially, this is what Archimedes (c.287 – 212 BC) observed when he stated that:

What is the ultimate strategy for winning at rock-paper-scissors? According to three physicists in China, the answer does not lie in having absolutely no strategy and ensure that your choice of weapon is completely random, unlike previously thought. If that strategy seemed obvious, perhaps you haven’t played the game enough to delude yourself into thinking that this might be a winning strategy…
They are found everywhere in Nature. From the leaf arrangement in plants, to the pattern of the petals of a flower, the bracts of a pine cone, or the scales of a pineapple. The Fibonacci numbers are applicable to the growth of every living thing: a single cell, a grain of wheat, a hive of bees, all of mankind. From sunflowers to sea shells, the same recurrent mathematical pattern can be observed in Nature, again, and again, and again…

Break a magnet into two pieces, and what do you obtain? What you get, unsurprisingly perhaps, are two new magnets – each one with two sides of opposite polarity. You don’t get a north half and a south half. Back to square one, it seems…
Please take a moment to enjoy this thing of great beauty… Simple to look at. Yet incredibly profound. Does it get any better than this?
