How Did Something Come From Nothing? : Questions do not come much deeper than this and until the 1970s only theologians and philosophers felt able to take it on (plus physics students still in the bar at closing time)
Why Can’t We Travel Faster than the Speed of Light? – This might be news to some of you but if you’re familiar with Einsteins theory of relativity, and that most famous of equations E=mc2, you’ll understand the limitations imposed by the equation. But exactly why should it be like this ?
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 ?
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.
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.
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?
What would you say if we said that you were able to see Neutrinos – small sub-atomic particles – with the naked eye.I don’t think you’d believe us. So it will come as a surprise that one of the smallest and lightest of particles can be observed by anyone with a pair of eyes.
We like to think that science has all the answers and that the more we learn the more we’ll be able to predict and control our environment. But what if there was a limit after which there’s too much uncertainty.
The pursuit of science is based on the belief that the explanations we seek are comprehensible to the human brain. But supposing they’re not? What if no human brain is well enough equipped to understand the universe. What if we are fooling ourselves?
We are Stardust … the chemical elements that make up our bodies, originated, with one exception, in the turbulent body of a star
Nuclear fusion is the energy source of the future. It promises to be a safe, clean and supply virtually limitless energy source. But how will it likely work?
The most accurate time piece today is an Atomic Clock. But how does it work & what’s the theory behind it ?
Why is it that we don’t fall through the floor? What’s stopping us ? A stupid question, surely ? … not really when you consider what an atom is made up of.
