The human mind and human memory is truely one of the wonders of the world that we live in. Somehow experiences, knowledge can all be stored in our brain and recalled in split second almost by an unbidden instinct. In this article we look at some of the chemistry and biology (that we know of so far) behind this miracle of nature.
An odd question and an even odder answer when we say that it’s because “you can’t unspill milk or unshatter a glass”. In this article we explain what this means.
As the reasons roll around we accept it as a natural part of life; Autumn arrives, the days get shorter and the leaves fall from the trees. But why is it this way? Why do trees drop the very means by which they gain sustenance? Why not just hang on to them at least until the new Spring growth ?
Here at guernseyDonkey.com we like to ask (and try to answer), some of life’s bigger questions: What is reality, what is consciousness … “How do Spiders build their webs over such long distances ?
If ever there was a unifying World language it would be that of numbers. The 10 digits we utilise are in universal use throughout the world. You have no problem ‘conversing’ with anyone in any culture. In this article we look at the remarkable story of numbers and how one man helped to introduce them into the European ‘vocabulary’ .
How do plants feed? The answers quite ingenious … most plants create meals for themselves in the form of sugar. This process is called photosynthesis (‘photo’ meaning light and ‘synthesis’ meaning to make) in other words making food with light !
A litre of seawater contains about 7 teaspoons of salt – that’s about 35g. But how did it get so salty ?
We know that the Earth’s core is hot, but not how hot. Actually, even geologists don’t know exactly what the temperature is, either, but they know it is almost as hot as the sun. Now that’s hot ! In this article we look at what’s going on down there and why it’s so hot.
It used to be thought that there was no special reason for sleep, however we now know it does have a purpose and function, but we’re not entirely sure what it is yet. In this article we look at the probable reasons for sleep.
How did the Romans do the calculations necessary for construction and other purposes using Roman numerals?
The Romans were skilled architects and engineers the likes of which the world had not seen before. They built huge elaborate and perfectly balanced structures that are not only still standing but still in use 2,000 years later. However their number system, whilst useful, was anything but straight forward. So how did the Romans manage to do the calculations necessary for construction using this rather unwieldy number system ?
Asking ‘Why did the dinosaurs die out?’, most people would say that it was a vast meteorite that hit the earth wiping out much of the animal and plant life. Whilst undoubtedly this was a major contributing factor it is only part of the reason.
Why do we get old ? Some animals can seem to live forever 200, 300 even 400 years. Various theories in biology have been put forward regarding ageing. We look at some of them in this article.
This topic of this article is born out of pain and suffering, quite literally I’m afraid. Why do Mozzie bites itch so much ?. How can something so small cause so much misery ?
Stop and think for a moment , we live in a world where our main number system is in base 10 so why do we have the rather odd base 60 for time and angles. Why not decimal time or decimal segments to represent angles in a circle ?
