WHY DID THE DINOSAURS DISAPPEAR?
About 65 million years ago, according to a theory, one asteroid more than 6 to 7 miles across struck the coast of Mexico’s Yucatan Peninsula. The impact created the Chicxulub crater, more than 110 miles wide, and caused a gigantic dust cloud. The dust settled, forming the layer of an indium rich clay which is now found in sedimentary rock under the Atlantic and Pacific Oceans and in most northern landmasses. The cloud likely caused the world temperatures to drop linking this global cooling to the extinction of dinosaurs.
VALUE OF CHOCOLATE
Etymologically, meaning, “food of the Gods”, cocoa is one of the natives of the American culture considered sacred and also medicinal. It originally comes from the poorest of the states of Africa and is sold in the richest parts of the world. Nearly, 5,000,000 tonnes of cocoa are produced every year, harvested at the lowest but sold at the highest rates.
WHAT DO B.C. AND A.D. MEAN?
B.C. stands for ‘before Christ’ and A.D. stands for anno Domini, Latin for “in the year of the Lord.” Both originated as per the dates that the scholars took as the basis for dating the birth and death of Jesus Christ. Some historians prefer C.E. and B.C.E. i.e. Common Era and before the Common Era. Dates in both the systems are identical but B.C. and A.D. are widely used.
WHO WERE THE EARLIEST MATHEMATICIANS?
With a flourishing agricultural economy, ancient Babylon, located in modern-day Iraq, was one of the first societies complex enough to need modern record keeping. The ancient Babylonians were thus among the first to develop a good counting system. They later came to be known for their Pythagorean Theorem.
WHAT IS THE ZODIAC?
The zodiac is a set of constellations that extends approximately nine degrees on each side of the ecliptic, the sun’s certain yearly path through the sky. Greek Historians divided the zodiac into 12 parts. These parts are called signs. Factually Zodiac is an “ecliptic coordinate system”, which takes the ecliptic as the basis of the latitude, and the position of the Sun at “vernal equinox”, as the basis of longitude.
