Science Vs Beliefs

అందరికి నమస్కారములు.

It gives immense pleasure writing this post...

Right from childhood, many of us would like to know differences or comparisons between Science and Beliefs. For me personally, has burning desire to know about beliefs(sayings)...which come out from old people or ancestors ...why do they tell so.....do that,do this, this is good, this is not good, this is bla bla, that is bla bla.... for a modern student all these things will give some irritation unless it is scientifically proven. But from my past experiences we can believe some of things (i don't know whether scientifically proven or not).

Here are some:

> In a place like Andhra Pradesh, for most of the festivals and small homely functions, we see decorating our doors and entrances, main windows with mango leaves or small mango branches.

Why do they do so. If you ask your ancestors they can't explain scientific reason as they are following their ancestors foot steps. But the reason behind it is, Mango leaves give pleasant smell as well as fresh Oxygen. On the eve of festivals or functions many relatives will join together. To overcome problem of suffocation, in each and every part of home people places mango leaves or branches.

> Don't cut finger nails in the night time.

Many of us have very strong nails and these are fastest growing areas of human body and poisonous too. If some body cuts theit nail and leave at the place where they cut (our ancestors do not make use of dust bins regularly), it leads to cutting of some body's foot and also it is very dangerous. This is the reason for that saying.

> Don't cut your hair on Tuesdays

Barbers needed holiday in their profession. So they themselves cannot be granted holiday. But if you create a belief in people it should followed by all. So they created a belief in people that if anybody cut their hair on Tuesday, it is bad for their health or wealth......

please update me if you are also familier with some other beliefs or sayings...
