A bar of soap is a chemical miracle – a little scented block that unleashes molecular forces when dunked in water. In this article we look how this little miracle actually works.
Chameleons camouflage themselves in a variety of different ways but most famously by changing the colour and pattern of their skin.
“We no longer have to wonder what self-awareness looks like – we can see it for ourselves” : A bold statement indeed. What we’re referring to here though is that scientists now believe that they can trace where they think conscientiousness physically sits in the brain
Fire – one of the most primitive and yet intriguing of the ‘fundamental elements in our world. Indeed one of the things that differentiates mankind from the rest of the animal kingdom is his ability to make and control fire. but : What is fire made of ? What is its atomic structure? What causes things to burst into flame in the first place and why can’t all materials be made to produce flame ?
As children, many of us learn about the wondrous process by which a caterpillar morphs into a butterfly. The story usually begins with a very hungry caterpillar hatching from an egg. But what does that radical transformation entail?
The human body is a pretty remarkable thing to the point that it actually has several different types of internal clocks that helps to keep us ‘ticking along’ for both the daily and seasonal rhythms of life.
According to the theory of evolution shouldn’t the strongest organism live forever ? …. No. But the ‘answer’ as it stands is rather mind-bending
That matter is composed of atoms we take for granted … but can we hope to unravel what they actually look like ?
Burning, technically known as combustion, is a chemical reaction where a substance combines with oxygen and releases energy in the form of heat and light, which we see as flames. The substance starts off in a higher energy state, and by combining with oxygen ends up in a lower energy state.
In the springtime we see migratory birds returning to us whilst in the Autumn we bid them farewell as they head for warmer southern climes. But how do they know when to leave our shores ? – and why do they bother to return again ?
The simplest of experiences can hatch eureka moments. Legend has it that despite all his inherited wealth and global travels, the ancient Greek philosopher Democritus hit upon one of the most fundamental of ideas in physics while sitting in the comfort of his own home.
One of the most common and baffling science questions is “how does gravity work?”. If you too find yourself confused then rest assured you’re in good company … even Sir Isaac Newton admitted he was baffled by gravity. In this article we look at Einsteins solution to this conundrum.
The popular image of an atom-smasher – or particle accelerator – is of a device that somehow smashes atoms together with such high energy that they break apart and we can see what’s inside them – but is this true ? What goes on in these mysterious machines ?
The Autumn display of colours when trees begin to lose their leaves is a pretty spectacular thing. But why and how does it occur?
