Moon is not the only satellite of the Earth....

There are satellites called as Quasi-satellite which are sometimes incorrectly referred as the Other moons of Earth. One of the most prominent quasi-satellite is 3753 Cruithne. Quasi satellites are in such Co-orbital configuration with planets that they revolve around the host star in the same time period. They have an Orbital resonance of 1:1.
Also there are Earth trojans, which lead or follow Earth in some orbit, while revolving around the sun. Only one Earth Trojan, 2010 TK7, has been found so far.
Meet the other moon of the Earth: 3753 Cruithne.

It's crazy, complete orbit:

Who invented the internet?

As you might expect for a technology so expansive and everchanging, it is impossible to credit the invention of the Internet to a single person.Long before the technology existed to actually build the Internet, many scientists had already anticipated the existence of worldwide networks of information. Nikola Tesla toyed with the idea of a “world wireless system” in the early 1900s, and visionary thinkers like Paul Otlet and Vannevar Bush conceived of mechanized, searchable storage systems of books andmedia in the 1930s and 1940s. Still, the first practical schematics for the Internet would notarrive until the early 1960s, when MIT’s J.C.R. Licklider popularized the idea of an“Intergalactic Network” of compute...

let's learn java today..

java(it’s hot!!) as you know in the market java is very popular.why java is hot now a days..??i’ll explain but before that will review the history of java so that we can understand the importance of this “hot cake”. history of java: java came in to picture in 1990s when c++ was very popular all over the world.the only disadvantage with c++ is c++ is platform dependent.so to solve this problem java came into picture.so what is platform independent and what is platform dependent. platform dependent and platform independent?? during the execution of any program the “cpu” or “micro processor ” will expect that the language compilation and the election platform must be same.so these kind of programing language is called platform dependent language. ex: if program is written in windows platform that object file must be executed only in windows platform.ex:c,c++ so what is platform independence ..yeah exactly opposite to this.during the execution of the program microprocess...
