## The why behind ‘1+1=2

I was satisfied and thought that that question was now filed. After having joked about it, questioned my kid brother, emailed astronomers and googled it, I think I now finally have a rather good and simple answer to why behind 1+1=2.

“In number base systems higher than ‘2’, 1+1=2 because it is defined as such. Based on definitions of number ‘2,’ number ‘4’ and mathematical operation of addition, answer is always same.”

Such a simple question, which is at base of so many complex equations, isn’t that simple after all, is it? There is actually an entire book, Principia Mathematica by Whitehead and Russell (not one by Sir Isaac Newton) which devotes several hundred pages to deriving and explanation of just why 1+1=2.

## Cellphones are the devil’s work

Cellphone radiation has yet another effect on your grey matter. It increases blood-vessel permeability in brain. This permits molecules normally excluded from brain to seep in. This same thing happens in rats’ brains. It is now thought that this bleach in blood-brain barrier may be accompanied by death of brain cells. If however you like fact that all types of I-don’t-know-what molecules are pouring into your ‘defeated’ brain, then only may you continue to use your cellphones regularly. But don’t blame me; blame yourself.

And yes; you’re right! A rat’s brain is not like a man’s one. In fact energy absorbed by rat is really low compared to what a person gets when using a cellphone! And what if effects add up over time? Maybe your head will literally explode.

Neuroscientist, W. Ross Adey of Loma Linda University says, “You have to ask, ‘How much can people handle before it becomes a significant problem?’”

Cellphones may come in handy when you’re in need. But remember that many of your cells are dying every time you pick up cellphone. Hang up!
