MORSE codes....

Morse code is a type of character encoding that transmits telegraphic information using rhythm. Morse code uses a standardized sequence of short and long elements to represent the letters, numerals, punctuation and special characters of a given message. The short and long elements can be formed by sounds, marks, or pulses, in on off keying and are commonly known as "dots" and "dashes" or "dits" and "dahs". The speed of Morse code is measured in words per minute (WPM) or characters per minute.

Originally created for Samuel F. B. Morse's electric telegraph in the early 1840s, Morse code was also extensively used for early radio communication beginning in the 1890s. In the early part of the twentieth century, the majority of high-speed international communication was conducted in Morse code, using telegraph lines, undersea cables, and radio circuits. However, the variable length of the Morse characters made it hard to adapt to automated circuits, so for most electronic communication it has been replaced by machine readable formats, such as Baudot code and ASCII.

The most popular current use of Morse code is by amateur radio operators, although it is no longer a requirement for amateur licensing in many countries. In the professional field, pilots and air traffic controllers are usually familiar with Morse code and require a basic understanding. Navigational aids in the field of aviation, such as VORs and NDBs, constantly transmit their identity in Morse code. Morse code is designed to be read by humans without a decoding device, making it useful for sending automated digital data in voice channels. For emergency signals, Morse code can be sent by way of improvised sources that can be easily "keyed" on and off, making Morse code one of the most versatile methods of telecommunication in existence.\

Applications for the general public

Representation of SOS-Morse code.

An important application is signalling for help through SOS, "· · · — — — · · ·". This can be sent many ways: keying a radio on and off, flashing a mirror, toggling a flashlight and similar methods.

rare facTS about FroG

A species of frog thought to have been extinct for 30 years has been found in rural Australian farmland, officials said Thursday.
It's not that easy being green, or any other color, in Earth's changing climate.

The rediscovery of the yellow-spotted bell frog is a reminder of the need to protect natural habitats so "future generations can enjoy the noise and color of our native animals," said Frank Sartor, minister for environment and climate change.





<>.Frogs drink and breathe through their skin. This is something very interesting that a lot of us don’t know. Instead of swallowing water like we do, frogs usually absorb the moisture needed through their skin. This is also how the get extra oxygen. This is probably why we always find frogs in moist areas

<>.Frogs eyes are very cool. They can be a variety of colors including gold

, brown, silver and green. Can you imagine having gold eyes? How cool is that? The shape of frogs’ eyes can also vary. You may see that the pupils are horizontal, round or heart shaped. Some are even triangular or star-shaped!

Two headed snake !!!!!!!!!!!!!!

This is a rare two headed snake found by a farmer in a village in Alicante, Spain. The chances of a two headed snake surviving in the wild is very slim as both would often fight over which head will swallow the prey as well as difficulty in deciding which direction to go.

Amazing facts about Indian education history..

<>.Algebra, Trigonometry and Calculus are studies which originated in India.

<>.The number system was invented by India. Aryabhatta was the scientist who invented the digit zero.

<>.The' place value system' and the 'decimal system' were developed in 100 BC in India.

<>.The World's first university was established in Takshila in 700 BC. More than 10,500 students from all over the world studied more than 60 subjects. The University of Nalanda built in the 4th century was one of the greatest achievements of ancient India in the field of education.

<>.Bhaskaracharya rightly calculated the time taken by the earth to orbit the sun hundreds of years before the astronomer Smart. His calculations was - Time taken by earth to orbit the sun: ( 5th century ) 365.258756484 days.

<>.The value of "pi" was first calculated by the Indian Mathematician Budhayana, and he explained the concept of what is known as the Pythagorean Theorem. He discovered this in the 6th century, which was long before the European mathematicians.

<>.Algebra, trigonometry and calculus also orignated from India. Quadratic equations were used by Sridharacharya in the 11th century. The largest numbers the Greeks and the Romans used were 106 whereas Hindus used numbers as big as 10*53 ( i.e 10 to the power of 53 ) with specific names as early as 5000 B.C. during the Vedic period. Even today, the largest used number is Tera: 10*12( 10 to the power of 12 ).
