In 1679, Denis Papin, a French physicist, who assisted Robert Boyle, used the latter's scientific discoveries and invented what is today one of the most commonly found kitchen equipment. His invention earned him a membership of the Royal Society of England. What was the invention?

Question

Adhir Mishra has three children: Urmila, Raghu and Sumit. Sumit married Roma, the eldest daughter of Mr. and Mrs. Mohan. The Mohans married their youngest daughter to the eldest son of Mr. and Mrs. Sharma and they had two children Sandeep and Shaifali. The Mohans have two more children, Roshan and Bimla, both elder to Sheila. Sohan and Shivendar are sons of Sumit and Roma. Leela is the daughter of Sandeep.

Answer 1

This question is best answered as Pressure Cooker, and it is worth noting that the original published key marked Fork, which does not match the historical record. Denis Papin worked as an assistant to Robert Boyle and applied Boyle's findings on gases and pressure to build a closed cooking vessel in 1679, known as the "steam digester" or "Papin's digester." By locking steam inside under pressure, the device cooked food, including tough bones, far faster than any ordinary pot of the time, and it is the direct ancestor of today's pressure cooker as well as an early influence on autoclave technology used in sterilizing equipment. This breakthrough is precisely what earned Papin his Fellowship in the Royal Society of England in 1680.

The fork and the knife are utensils that predate Papin by many centuries, tracing back to ancient Middle Eastern and European dining customs, so there is no historical thread connecting either of them to his scientific work. A kitchen stove is a heat-generating appliance, which is also unrelated to what Papin actually built, since his device was about trapping pressure rather than producing heat. Given how clearly documented the steam digester story is in the history of science, Pressure Cooker is the historically accurate answer here, even though it differs from the answer originally marked as key.
