- What are wave snakes?
Wave snakes are long, red tubes that help convert the motion of waves into electricity and form part of a commercial wave power station. It was developed by a British company and took ten years to create. Currently the pilot wave power project has been launched off the coast of a Portuguese town called Agucadoura and aims to power 1,000 families home’s in it’s initial phase.

3.What is the God particle?
God particle is the nick name given to Higgo boson particle, so far a hypothetical subatomic particle believed to impart mass to the atom and eventually to all matter in the universe.

4. What is Munchausen Syndrome?
Munchausen Syndrome also known as hospital addiction, factitious illness, afflicting those referred to as professional patients is a repeated fabrication of clinically convincing simulations of a disease for the purpose of gaining medical attention. It refers to patients who wander from hospital to hospital feigning acute medical or surgical illness and giving false and fanciful information about their medical and social background for no apparent reason other than to gain attention. The cause is unclear, prognosis poor and the treatment is often unsuccessful in these psychiatric patients.
5. What is Einstein’s Rule of 72?
The Rule of 72 is a rule of thumb credited to Albert Einstein that investors use to approximate the time it takes for money to double at a given rate of return. It states that if you divide the number 72 by any given rate of return the answer you get is the time it takes for money to double at that given interest rate, assuming you can get the same rate each year and it is compounded annually. For eg if you earn 10% on your money it would double in 7.2 years(72 divided by 10=7.2)The value 72 is a convenient choice of numerator since it has many small divisors, 1,2,3,4,6,8,9,12.It provides a good approximation for annual compounding and for compounding at typical rates(from 6% to 10%).The approximations are less accurate at higher interest rates.
6. What does Acropolis mean?
Acropolis is a Greek term and refers generally to an elevated area in the centre of a city, acting as it’s focal point for cultural, religious and civil activities. In particular the term refers to the rocky hill at the centre of Athens, Greece on which are located several ancient monuments including the famous Parthenon, the temple for the Goddess Athena constructed around 5th century B.C. In Greek, Acro means high and polis means city. All ancient cities were supposed to have been first set up on elevated areas primarily for defence. Even after a city grew around the initial elevated area, the elevated area continued to act as a nucleus for the city’s growth and culture. By generalization of the term Acropolis it is now used to refer to a central complex of structure in some cities.
7. What is creative capitalism?
Creative capitalism is an approach where governments, businesses and nonprofit organizations work together to stretch the reach of market forces so that more people can make a profit or gain recognition and do work that eases the world’s inequities.

9.What is the Captcha Project?
The term CAPTCHA was coined over fifteen years ago. They have been through many changes over these years. It is an acronym for ‘Completely Automated Public Turing Test To Tell Computers And Humans Apart.’ It is also known to be a particular type of challenge-response test and other than trying to tell humans and computers apart it is a web-based protection mechanism. It was introduced in the year 2000 by Luis von Ahn, Manuel Blum, Nicolas J. Hopper and John Langford. The main uses of CAPTCHA are to prevent comment spam in blogs, protect website registration, protecting email accounts from scrapers, online polls and prevent dictionary attacks. Most of us must be familiar with programs that submit bogus comments in the hope of raising search engine ranks of a certain website. By using CAPTCHA only humans would be able to make a post on the comment section of the blog.
10. What is a false vacuum?
In quantum field theory, a false vacuum is a hypothetical vacuum that is not actively decaying but somewhat is not totally stable. It may last for a very long time in that state, a property that is known as metastability and might eventually move to a more stable state in an event known as Vacuum decay. A false vacuum exists at a local minimum of energy and so is not stable in contrast to a true vacuum which exists at a global minimum and is stable.
11.What is the dissociative identity disorder?
Dissociative Identity disorder(DID) previously known as Multiple Personality Disorder(MPD) is a mental disorder characterized by the maintenance of at least two distinct and relatively enduring personality states. The disorder is accompanied by memory gaps beyond what would be explained by ordinary forgetfulness. Some other conditions that often occur in people with DID include post-traumatic stress disorder, personality disorders, depression, substance use disorders, conversion disorder, somatic symptom disorder, eating disorders, obsessive-compulsive disorder and sleep disorders.
12. Why does the moon appear upside down in the southern hemisphere?
The moon does appear ‘upside down’ in the southern hemisphere as compared to the northern hemisphere but it is simply a matter of orientation. If we imagine the moon orbiting in the same plane as the equator and if we were in the northern hemisphere the moon would always appear in the southern sky as that is the direction of the equator. The reverse is true in the southern hemisphere, the moon would appear in the northern sky.
So the two observers are looking at the same object from opposite directions and naturally it means one sees the object flipped compared to the other. It means that the ‘man in the moon’ is upside down in the southern hemisphere and can actually look more like a rabbit.
