QUES: Beyonce announced a hiatus from her music career in January 2010, heeding her mother's advice, "to live life, to be inspired by things again". During the break she and her father parted ways as business partners. Beyonce's musical break lasted nine months and saw her visit multiple European cities, the Great Wall of China, the Egyptian pyramids, Australia, English music festivals and various museums and ballet performances.
Which famous landmark did Beyonce see in China?

ANS: the Great Wall of China

QUES: Energy transformations in the universe over time are characterized by various kinds of potential energy that has been available since the Big Bang later being "released" (transformed to more active types of energy such as kinetic or radiant energy) when a triggering mechanism is available. Familiar examples of such processes include nuclear decay, in which energy is released that was originally "stored" in heavy isotopes (such as uranium and thorium), by nucleosynthesis, a process ultimately using the gravitational potential energy released from the gravitational collapse of supernovae, to store energy in the creation of these heavy elements before they were incorporated into the solar system and the Earth. This energy is triggered and released in nuclear fission bombs or in civil nuclear power generation. Similarly, in the case of a chemical explosion, chemical potential energy is transformed to kinetic energy and thermal energy in a very short time. Yet another example is that of a pendulum. At its highest points the kinetic energy is zero and the gravitational potential energy is at maximum. At its lowest point the kinetic energy is at maximum and is equal to the decrease of potential energy. If one (unrealistically) assumes that there is no friction or other losses, the conversion of energy between these processes would be perfect, and the pendulum would continue swinging forever.
Name another example of a heavy isotope.

ANS: thorium

QUES: In 1671, Robert Boyle discovered and described the reaction between iron filings and dilute acids, which results in the production of hydrogen gas. In 1766, Henry Cavendish was the first to recognize hydrogen gas as a discrete substance, by naming the gas from a metal-acid reaction "flammable air". He speculated that "flammable air" was in fact identical to the hypothetical substance called "phlogiston" and further finding in 1781 that the gas produces water when burned. He is usually given credit for its discovery as an element. In 1783, Antoine Lavoisier gave the element the name hydrogen (from the Greek - hydro meaning "water" and - genes meaning "creator") when he and Laplace reproduced Cavendish's finding that water is produced when hydrogen is burned.
Who recognized hydrogen gas as a discreet substance?

ANS: Henry Cavendish

QUES: During the early 20th century it became increasingly common to bury cremated remains rather than coffins in the abbey. In 1905 the actor Sir Henry Irving was cremated and his ashes buried in Westminster Abbey, thereby becoming the first person ever to be cremated prior to interment at the abbey. The majority of interments at the Abbey are of cremated remains, but some burials still take place - Frances Challen, wife of the Rev Sebastian Charles, Canon of Westminster, was buried alongside her husband in the south choir aisle in 2014. Members of the Percy Family have a family vault, The Northumberland Vault, in St Nicholas's chapel within the abbey.
