Peruvian Amazon ants
An unbelievable number of 43 species of ant can be found on a single tree in the Peruvian Amazon, which is equal to the entire ant fauna of the UK!
The Oldest Trees
The Bristlecone Pine is the oldest known tree species in the world. It is found only in the scattered, arid mountain regions of six western states of America, in a harsh windswept environment. The oldest Bristlecone Pines grow at an elevations of 3,000 to 3,300 metres, and the oldest known tree is 'Methuselah', which is 4,789 years old!

Electric Bulb
Why is Thomas Alva Edison considered to be the inventor of the electric bulb?
The actual inventor of the very first electric lighting was Humphrey Davy. In 1809, he invented the original source of electric lighting. Since his invention, many other men had set out to improve this idea and invent their own form of electrical lighting. Many have succeeded, but none were practical or long lasting.
It was only in 1879 that Edison invented a carbon filament that would burn for at least forty hours. With his great mind and wonderful thinking, he had made a longer lasting electric light bulb in 1880. It burned for over 1,200 hours, using a bamboo-derived element.
So, though there were very many men trying to invent longer, safe, and economical electric lighting, it was Thomas Alva Edison who did the best job. He made quite a few improvements on his improvements on his invention too. Edison spent several years after this, putting together the electric industry, so that this new source of lighting would be used throughout the world, on streets, in homes, and in businesses.

Some more fun stuff
The following is for those of you who have learnt some Geometry. I wanted to show you a simple proof of Pythagoras theorem and, for that, you need to understand the following. Feel free to ask questions if you do not understand something.
In the diagram above, PQ and XY are parallel straight lines (what does it mean?).
And, AB=BE (that means, if you slide the green parallelogram along the parallel lines as below, you will see that the base of the green parallelogram coincides with the base AB of the rectangle).
FACT: If you have such a set up as the green parallelogram and the red rectangle as seen here, then the area of the rectangle is same as the area of the parallelogram.

Believe it or not!
Bourke's Luck
Bourke's Luck Portholes are swirling whirlpools which occur as the Treur River plunges into the Blyde River. They were named after Tom Bourke, a farmer on whose land the portholes were located. Tom Bourke correctly predicted that large gold deposits would be found at the bottom of his potholes - and he was right!
