Welcome back to BYJU’S Sunday Challenge! In this edition, we explore accidents through history that unexpectedly led to fortunate discoveries and inventions. The topic for the week is ‘Serendipity’!
Remember:
You can take a shot at the questions and field your guesses in the comments section below. Answers will be revealed on subsequent Sundays in the comment section.
Ready? Here are your questions:
Question 1
The word ‘serendipity’ means ‘unexpected discovery’ or ‘fortunate chance’. The word derives from ‘Serendip’, the old Persian name for an island nation that is known by a different name today. The word Serendip itself is thought to be derived from ’Sinhaladvipa’. How do we better know the country today?
Question 2
In 1946, a young engineer at the Raytheon company, Percy Spencer was walking past a military-grade magnetron when he noticed that the chocolate bar in his pocket melted. What serendipitous invention followed as a result of this?
Question 3
This process of fortifying rubber was chanced upon by a 19th century American chemist and entrepreneur when he accidentally dropped some sulphur into liquid rubber. This process is named after the Roman God of fire. Name the process and the chemist (pictured below).
Question 4
During World War II, Dr Harry Coover was conducting research with chemicals known as cyanoacrylates in an effort to find a way to make a clear plastic that could be used for precision gunsights for soldiers. While working with the chemicals, he discovered that they were extremely sticky, and this property made them very difficult to work with. Cyanoacrylates found no use in the war effort but a decade later they became popular for a completely different reason, and are used widely even today. How do we better know cyanoacrylates?
Question 5
On a hiking trip in 1941, Swiss engineer Georges de Mestral found burrs clinging to his pants and his dog’s fur. On closer inspection, he found that the burr’s hooks would cling to anything loop-shaped. He tried to artificially replicate this and this led to a serendipitous invention used widely even today. What did he create?
Leave your guesses in the comments section below. And remember, answers will be revealed next Sunday in the comments section too, along with a brand new edition of BYJU’S Sunday Challenge.

Answers-

3.Charles Goodyear discovered the process of ‘Fortifying Rubber’!
4. Cyanoacrylates is known as ‘Super Glue’!
Sagnik Brata Chatterjee
July 22, 2021
Ans. 1) The country is better known as “Sri Lanka”. “Serendip” or “Sinhaladvipa” was the ancient Persian name for the island of Sri Lanka.
Ans. 2) Scientist Percy Spencer invented the “Microwave” serendipitously while working with military-grade magnetrons. When the chocolate bar in his pocket had melted, he realized that the waves emitted by magnetrons could be utilized to cook food.
Ans. 3) American chemist and entrepreneur Charles Goodyear discovered ,or rather invented, the process of fortifying rubber. The process was named “vulcanization”, after the ancient Roman God of fire “Vulcan”.
Ans. 4) Cyanoacrylate, better known as “Super Glue” is used as an adhesive, a hemostatic agent or to “glue” tissues together in a minor wound. It was invented (serendipitously) by Dr. Harry Coover along with Fred Joyner (who was a researcher in Dr. Coover’s lab).
Ans. 5) Swiss engineer Georges de Mestral created the hook and loop fastener, by artificially replicating burr’s hooks. This was an accidental discovery, which led to the foundation of the organization called “Velcro”(in 1995, by Geoges de Mestral). It has become the common household name for the hook and loop fastener, since then.

ANS-1-Serendip is the Persian name for Sri Lanka, possibly from the Tamil “Seran Theevu” (Island of the Cheras).
ANS-2-The microwave oven was born.
ANS-3-Goodyear bought Hayward’s process. In 1839 he accidentally dropped some India rubber mixed with sulfur on a hot stove and so discovered vulcanization.
ANS-4-Cyanoacrylate glue is a fancy name for what is commonly known as Crazy or Super Glue.
ANS-5-He then worked on inventing hook and loop fasteners for ten years starting in 1948. In 1955 he successfully patented hook and loop

The answer to question 1 will be Sri Lanka and we know the country a lot better today.
The answer to question 2 will be the Microwave oven.
The answer to question 3 will be Charles Goodyear and the process is known as Vulcanization.
The answer to question 4 will be: Cyanoacrylates are a family of strong fast-acting adhesives with industrial, medical, and household uses. They are derived from ethyl cyanoacrylate and related esters. The cyanoacrylate group in the monomer rapidly polymerize in the presence of water to form long, strong chains.
The answer to question 5 will be hook and loop fastener

Answers to—
Question1: Sri Lanka
Question2 : well, I don’t think I know the answer for this question…..but I’m guessing this to be the beginning of hot chocolate…
Question3: I have an idea about the Roman mythology, according to which, roman God of Fire must be Vulcan. So, prolly the process must be Christened Vulcanisation. (This is the best name i could Christine)
Question4: I guess, cyanoacrylates have evolved to become popular super glues, given that they are quite sticky.
Question5: A wild guess again—-the description seems to be hinting towards some sort of a fastener.

Question 1 answer =Serendipity is an unplanned fortunate discovery.[1] Serendipity is a common occurrence throughout the history of product invention and scientific discovery. Serendipity is also seen as a potential design principle for online activities that would present a wide array of information and viewpoints, rather than just re-enforcing a user’s opinion.
