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.
Slugs (and vampires) watch out! – Researchers at Newcastle University have found eco friendly ways to kill them.
If you have the opportunity to speak with any fish, I suggest you don’t choose herring. Herring communicate by shooting a burst of bubbles out of their anus. In this article we look at Fish Communications.
When animals, plants and other organisms die, they typically decay completely. But sometimes, when the conditions are just right, they’re preserved as fossils. In this article we take a look at how that process occurs.
Is the Earth’s magnetic field about to flip? – As it says on the cover of venerable “Hitch Hikers Guide to the Galaxy … “DON’T PANIC” (yet). But here’s a curious thing : The strength of the Earth’s magnetic field has decreased by 10% over the last 150 years.
The Caloric value of food appears everywhere today. It’s almost as if there’s some malevolent conspiracy to make us feel bad about that chocolate bar or bag of crisps we like to snack on. But how do they estimate the calorific values and is it very accurate ?
