The first Indian, and for that matter the first Asian, to win the Kalinga Prize for science popularisation instituted by the UNESCO is Jagjit Singh in 1963 for his books such as Mathematical Ideas: Their Nature and Use and Modern Cosmology.
Where did ‘Karate’ develop?
Karate which literally means “empty hand” had its beginnings in the 5th century AD and is attributed to a Zen Buddhist priest called Bhodi-dharma.
In those days the Buddhist priests are said to have deve-loped proficiency in self-defence, based on yoga techniques.
Bhodi-dharma is said to have gone from India to China where he taught yoga tech¬niques at the Shaolin monastery. Later, he is said to have introduced the Chinese fighting method, called kempo, into his training schedule. Vital parts of the body identified in acupuncture were made target areas of attack in kempo and later formed the basis for attack areas of karate.

What is the avian influenza virus?
This is a virus that has been circulating among birds and typically does not infect human beings. There are, however, three main sub-types of this virus that are known to infect both birds and humans. These are avian influenza A H5, H7 and H9. Nine potential sub-types are known for each of these three, i.e. 27 in all.
Of these 27 known sub-types, so far only five have infected humans. Among them, avian influenza A (H5N1) is the most well known. It is circulating among poultry in as many as 15 countries. In the past, H7N2, H7N3, H7N7 and H9N2 have also infected human beings, causing effects ranging from mild illness to death.
How does a wireless mouse work ?
A mouse is a very important peripheral device in a computer which is used to move the cursor on the computer screen. It has several other buttons which are used to highlight a part of text, images or other information, to scroll pages, to click and open files, folders, etc.
In case of a wired mouse, the information from the mouse to the CPU and back are transmitted through a pair of wires. In case of wireless mouse, these pieces of information are exchanged through radio signals. To support this arrangement, there is a radio transmitter in the mouse and a corresponding receiver in the computer. The radio frequency receiver receives the radio frequency signals, decodes them, and then sends these signals to the computer
as normal. RF receivers usually come as built-in components that connect to the mouse input. In some cases, a separate card is installed in the computers.
Most wireless mice have integrated receivers that plug into a computer’s peripheral input and are very small in size. Wireless mice mainly use radio frequencies at 2.4 gigahertz and at these frequencies a mouse can transfer data at very quick speed. Also there is very little or no interference in a work or home environment. They also have a good range of the order of 100 feet or so. Another technology that is used in wireless mice is Bluetooth RF technology. It uses 2.4 gigahertz frequencies. Bluetooth also has a decent range, usually about 20-30 feet.
