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 ?
Do you really need your Brain ? : WHAT !? … A joke surely. No, this is a serious question (sort of). To see why we might ask it though we need to look at a rather strange phenomenon first observed in the 1980s.
Doctor Doolittle may have been able to talk to the animals but what about plants ? Prince Charles is famous for his chatty behaviour towards his plant friends but, do plants ‘talk’ to each other ?
If the fact that all magnetic compasses don’t actually point to the geographical North Pole comes as a shock to you then what we discuss below will blow your socks off, because magnetic north actually moves year by year AND the poles have even flipped in the past; North is South & South is North!
This is one of those mysteries that refuse to lie down (if you’ll pardon the pun). It’s also one of those questions where there’s much debate and no clear answer. However there are some good theories that are interesting to chew over.
What is the largest recorded explosion you might think that it was the Hiroshima A-bomb or maybe Krakatoa? In fact the answer is neither. The largest recorded explosion occurred some 200 years ago and was a phenomenal 60,000 times the power of the Atom bomb dropped on Hiroshima in 1945..
How does moisture from the soil reach the top of tall trees? : This is one of those questions we all think we know the answer to but you’d be surprised to know what the answer really is.
Sometimes science really comes up with a way of proving something we felt was right all along. In this case researchers at the University of Maryland School of Medicine have confirmed what the editors at Readers Digest have claimed for years – that ‘laughter really is the best medicine.
So here’s a question you might idly contemplate as you lie back one summers evening gazing into star bright night sky watching as the planets, the moon and the stars idly move on by, “Will the Earth ever stop spinning ?”
When you look at pictures of our beautiful plant you can’t help but notice the startling blue of the world’s oceans. They occupy two-thirds of the planets surface but how did they get there ?
