Photographer's Note

An anemometer is a device for measuring wind speed, and is one instrument used in a weather station. The term is derived from the Greek word, anemos, meaning wind. The first anemometer was invented by Leon Battista Alberti.

Anemometers can be divided into two classes: those that measure the velocity of the wind, and those that measure the pressure of the wind, but as there is a close connection between the pressure and the velocity and a suitable anemometer of either class will give information about both these quantities.

You may think why i'am talking about anemometer.. i will tell you, I saw this gentle man in a temple at thirukazhikundram. In that day wind was bit heavier then normal... there i found this gentlemen beard moving the sides towards the flow of wind...that time i remembered this anemometer.

Now can you say by which side wind is blowing ??
