Deepest part of the Ocean System

Q: Where is the deepest part of the ocean system located?

A: The deepest part of the ocean system is the Mariana trench in the Pacific Ocean. First pinpointed in 1951 by HM Survey Ship Challenger, this trench is 1,500 miles long, averaging over 40 miles in width having maximum known depths of over 35,000 feet. On January 23, 1960, the manned US Navy submersible vessel Trieste descended to the bottom of the trench for the first time. On March 24, 1995, the unmanned Japanese probe Kaiko also reached the bottom, recording a depth of 35,797 feet, the most accurate measure of the trench ever made.

Humanoid robot

Q: When was the first humanoid robot designed?

A: In 350 BC, Greek mathematician Archytas of Tarentum built a steam-driven mechanical bird which can be termed as the first step towards the development of robot. Later, in around 1495 Leonardo Da Vinci of Italy planned and sketched out a humanoid robot in the form of a mechanical knight with anatomically correct joints operated by cables and pulleys. However, the word 'robot' was introduced by novelist and playwright karel Capek of Austria-Hungary in 1921 in one of his plays to depict artificial people. In 1989, the first walking robot 'Genghis' was developed at the Massachusetts Institute of Technology (MIT), USA. Later in 2000, ASIMO (Advanced Step In Innovative Mobility), a humanoid robot, was unveiled by Honda.

Remote Sensing..

Q: What is Remote Sensing?

A: Remote Sensing is the technique of collecting information by observing the surface of the Earth and other planetary bodies through sensors on aircraft and space satellites. The basic tool used here is photography-infrared and false colour photography in particular. Modern remote sensing satellites are equipped with special cameras which take photographs of any particular region of the Earth's surface in several colours simultaneously. These separate images can be electronically proceessed to produce multicolour images and maps outlining areas of specific interest such as diseased or pest-infected crops, forest areas and vegetation, rich fishing areas in seas, even underground water and mineral reserves. Remote Sensing is an indispensable tool for better monitoring and management of natural resources.

Judaism... origin....

Q: When did Judaism originate?

A: One of the most ancient belief systems, Judaism is the religion of the Jews. Judaism is the oldest of the monotheistic religions, which hold that there is only one god rather than a plethora of many different deities. The name of the Jewish God is Yahweh (Jehovah) and the holy book is the Torah. The historical origins of Judaism are disputed among scholars. However, followers of the religion believe that a man named Abram (later known as Abraham) left the Mesopotamian city of Ur for Cannan (Palestine), sometime around 1800-2000 BC. In Cannan, Abraham made a covenant with Yahweh, accepting him as the most important god and the ruler of the universe.
