What are carbon credits?

Credits can be sold in the international market at the prevailing prices via certain credit exchanges. Formalized in the Kyoto Protocol, carbon credits help developing/ underdeveloped countries as they traditionally have lower per-capita carbon emissions than developed countries and will need to emit CO₂ owing to increasing industrial growth. At this point though, these countries can sell their carbon credits to other countries and reap the economic benefits of not polluting the planet.

Why the number 1 is not considered a prime number though it fits the definition?

The number 1, in fact, does not fit the definition of a prime number. A positive integer is called a prime number only if there are exactly two divisors of that number. Since 1 has exactly one divisor (which is 1 itself), it does not fit this definition. Another equivalent definition of a prime number is this: a prime number’s only positive divisor should be less than 1 and itself. Again, 1 does not fit this definition either – there are no positive divisors of 1 which are less than 1.

What is known as the Baudhayan theorem?

Baudhayan Sulv Sutra (1000 BC) is today known as the Pythagoras theorem, which states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. In Baudhayan theorem, this has been expressed as follows: in a Deerghchatursh (triangle), the chetra (square) of rajju (hypotenuse) is equal to the sum of squares of the parshvamani (base) and triyangmani (perpendicular line). It is amazing to note that the Pythagoras theorem was known in our country as far back as 1000 BC.

What is gnotobiology?

Gnotobiology is the science of study of animals or other organisms rose in environments free of germs or those which contain only specifically known germs. Scientists compare gnotobiotic animals with ordinary animals whose bodies carry many germs, like bacteria, viruses and parasites. In this way, scientists can determine more precisely hoe specific germs affect a body.

Which nation has the smallest army in the world?

Vatican City, the world’s smallest country, has the smallest army. This army of 110 men is also known as the Swiss Guard. In the year 2006, the Vatican celebrated the 500^th anniversary of the Swiss Guard. The celebration commemorated the 150 Swiss Helvetian mercenaries who came to Rome to serve Pope Julius II, on January 22, 1506. The mercenaries covered a distance of 723 km in 27 days to enter Rome from Bellinzona, Switzerland. Swiss Helvetian mercenaries, famous for their courage, die-hard attitude and loyalty to their employers, were part of the regular armies of various countries at that time. As allies of the Pope, they helped to shape Italy’s destiny and thus they were granted the title ‘Defenders of the Church’s Freedom’ by the Pope. During the sack of the Rome on May 6, 1527, the Swiss Guard, comprising 189 personnel at that time, resisted a Spanish attack on Rome and the Vatican. But they had to retreat after suffering heavy casualties. Only 42 men survived the attack. However, the guard was able to ensure Pope Clement VII’s escape to safety.
