Why most people are RIGHT -HANDED?


Many animals show a preference for one side of the body over another, but the split between right- and left-handed varies.
  • Seven out of 10 chimpanzees are right-handed.
  • Almost all kangaroos are left-handed. 
  • In cats, males are nearly all left-handed and females are nearly all right-handed. 
Humans have a higher proportion of right-handers than any species, with left-handers making up just 10 per cent of the population.

The perfect reason is, "we are a tool-using species", and also highly social. We make use of things that are build by others. So, to match the hand pattern, people use same handed versions.
The very earliest flint tools, around two million years ago, don’t show a strong bias towards left- or right-handed versions.
 But it’s a big advantage if you can use the tools someone else has made, and, from about 1.5 million years ago, we seem to have standardised on the right handed versions. It’s not exactly clear why right-handedness won, but it may be that one side of our brain was already specialised for fine-motor control. One theory why left-handedness hasn’t been completely eliminated is that it provides an advantage in combat, precisely because it is rarer, and, therefore, unexpected. You can see this today in sports like tennis, where left-handed professionals are more common than in the general population.

Could JUPITER Become a Star?


Jupiter is often called a ‘failed star’ because, although it is mostly comprise of hydrogen like most normal stars, it is not gigantic enough to commence "thermo nuclear reactions" in its core and thus become a ‘real star’.

But the term ‘failed star’ is a bit of a misnomer. According to Theory, any object at all could be made into a star, simply by adding enough matter to it. With enough mass, the internal pressure and temperature of the object will reach the threshold needed to start thermo nuclear reactions. That threshold is the least for the simplest element, hydrogen. In order to turn Jupiter into a star like the Sun, for example, you would have to add about 1,000 times the mass of Jupiter.

But, to make a cooler ‘red dwarf’, you would only need to add about 80 Jupiter masses. Although the exact numbers are still a bit uncertain, it is possible that a ‘brown dwarf’ could still form (in which deuterium, rather than hydrogen, fuses in the star’s core) with only about 13 Jupiter masses.

So, Jupiter cannot and will not spontaneously become a star, but, if a minimum of 13 extra Jupiter-mass objects happen to collide with it, there is a chance it will.

The Magic of Fibonacci numbers



Let us look in the real world to find the traces of Fibonacci. In every bee hive, there is one female bee (queen) who lays all the eggs. If an egg is not fertilized, it ultimately hatches into a male bee, called a drone.

If an egg is fertilized by a male bee, then the egg produces a female bee (i.e, worker bee), who doesn't lay any eggs herself (unless she is fed something called royal jelly, in that case she will turn into a queen to challenge the existing one or fly off and start a new hive).

Now let's look at the family tree of a male. If we will count the numbers of parent, grand parent, great grandparents, great-great grandparents, great-great-great grandparents, great-great-great-great grandparents and so on of a male bee, we will find the Fibonacci sequence. 1, 1, 2, 3, 5, 8, 13...

These numbers are then used to derive the Golden Ratio. The Golden Ratio is 1.618. It appears naturally in almost all aspects of life i.e, family trees in bunnies, petals on a rose, body ratio’s in humans. It is said that people that are considered ‘naturally beautiful’ have a face and body that follows the golden ratio. Both the Fibonacci numbers and the Golden Ratio appear in Honeybees.
If you divide the number of female bees by the number of male bees you get 1.618, the golden ratio. This mathematical sequence work for any honeybee hive at any give time. Commonly, honeybee hives are always used to explain the Fibonacci Sequence and Golden Ratio.
