Rules of the Quiz• There are 28 questions in total, out of which 24 questions will follow normal

pattern and 4 will be written. There will be a warm-up question to get familiarised with the rules.

• The quiz will follow pounce+infinite bounce format. This will be explained by the QM shortly.

• Each correct answer gets you 10 points (part questions will be divided equally for points).

• No negative marks on direct and pass questions.

• Negative points (-5) if you get any answer wrong on pounce.

• All parts required in pounce to get points, part answers will give you -5.

Pounce Format Explanation

Infinite Bounce Explanation

Warm-up QuestionCarl-Johan Haster published a preprint on 11th May, 2020 where he calculated X using gravitational waves. The work began with Haster's observation that X appears in several terms of an equation describing propagation of waves. He treated X as a variable instead of as a constant and perturbed the quantities in the equations to see how well he could approximate X, and it came out to be 3.115. What is X?

Question 5

The Clock of the Long Now is under construction & is designed to keep time for 10,000 years.

Many options were considered for powering this clock like nuclear, solar power etc, but most were rejected. The designer Danny Hillis decided for regular human winding. However the clock is designed to keep time even when not being wound. How will then it be powered?

Question 7This protocol combines two different cryptographic algorithms to give end-to-end encryption for a certain type of communication channel.It uses the widely popular Diffie–Hellman key agreement protocol with a Double Ratchet Algorithm, which after an initial key exchange maintains several short sessional keys.Ratchet is a mechanical term, which is a ‘device’ that allows movement in only one direction, similarly the above algorithm allows generation of keys from previous keys. This is one reason why we see a certain phenomenon whenever someone changes her cellphone/number or updates their software.Where is this protocol used? What phenomenon do we see often?(5+5 points)

Question 11In Shakespeare’s Hamlet, Act V, Scene 2 , the protagonist mentions that God controls everything, including trivial events such as the death of a sparrow, and that everything works out in a fashion it was destined to be. Albeit, unscientific and irrational, one can draw analogies between the statement in the fictional world with that of the life of a pioneering individual who also happened to be a distant cousin of one of the presidents of Pakistan.

Name the individual and how a trivial event as described above shape his destiny.

Question 12During its manufacture, it is toughened by ion exchange. The material is immersed in a molten alkaline potassium salt at a temperature of approximately 400 °C (750 °F), wherein smaller sodium ions in the glass are replaced by larger potassium ions from the salt bath. The larger ions occupy more volume and thereby create a surface layer of high residual compressive stress at the surface, giving its surface increased strength, ability to contain flaws, and overall crack resistance, making it resistant to damage from everyday use.

Question W1A right-angled triangle with edge lengths in geometric progression is named after a key scientific figure who was famously described by an esteemed science communicator as "the first astrophysicist and the last scientific astrologer”,

The ratio of the edges of such a triangle is linked to the golden ratio, the squares of the edges of it are in geometric progression according to the golden ratio.

For an exact such triangle, the inclination of the sides should be oriented at specific angles. Certain reports mention that this angle have been used by the Egyptians in the construction of the Great Pyramid of Cheops.

After whom are these triangles named?

Question W4Sir John Randall was a famous physicist who is known for his efforts in contributing to the Allied victory in the Second World war as he supervised the radical improvement of the cavity magnetron, an essential component of centimetric wavelength radar.

In May, 1952, Randall’s student, while working with another scientist X, took an image of a paracristaline gel which has gone down in history as a seminal finding in the elucidation of the specific structure of a molecule. The picture has also been central to various debates and controversies that concentrated on sexism and prejudices prevalent in the scientific circles. Name the scientist X.

Question 22In 2019, researchers at the University of Copenhagen successfully extracted a complete human genome of a 5700 year old female from a piece of X. This was the first time that such a genome had been extracted from something other than human bones. X was made of birch pitch, which was used for glueing stone tools since the Palaeolithic era. Competing theories suggest that one use of birch pitch was as a X. Ancient X is a new untapped source of DNA which may also help understand how bacteria and viruses evolve. What is X?

Question 23Urbain Le Verrier is best known for predicting the existence of Neptune using only mathematics. But that is not the only planet predicted by Le Verrier. To explain some aberrations of the orbit of Mercury, he proposed that a planet, named X lay even nearer to the Sun than Mercury. The name was chosen in honour of a Roman God, due to its apparent proximity to the Sun. X was later discarded when a new theory explained the orbit of Mercury. X is probably the most famous fictional planet. What is X? And, which new theory?
