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?
In a nutshell … tides are caused by the gravitational attraction between the moon and the Earth. In this article we look at how.
In the days of analogue TV you turned into a channel through various UHF frequencies. If you stopped tuning before you found a channel, you’d see a screen full of ‘snow’ – white dots . Some of that ‘snow’ is a sign of the Big Bang , although nobody was aware of its significance until the 1960s.
You may have heard of the name ‘Gaia’ as the personification of the Earth, or mother Earth. But in this article we look at a serious hypothesis that relates to mother Earth as if she ‘acts’ as part of a global system.
Geologist often trot out some incredible facts without a second thought – “This rock is 4.4 billion years old…” said geologist Simon Wilde in 2001 as he introduced the oldest known piece of the Earth, but how did he know?
Sometimes science has a strange way of proving what every body else has known all along, so here it is : Apparently “Men and Women are different”. Not only that but their brains are wired differently!
Sunflowers are among several plant species – especially desert plants – that have the ability to either grow or move in response to stimuli from sunlight to maximise the amount of direct solar radiation received for photosynthesis and growth. Here’s how they do it.
