About this Famous Scientists quiz

This famous scientists quiz celebrates the people behind the ideas we learn in every science class, from Albert Einstein and Marie Curie to C.V. Raman, Jagadish Chandra Bose and A.P.J. Abdul Kalam. The 15 questions mix world-famous names with great Indian scientists, and they move from easy picks to a few hard ones about particles and stars.

It works well for school and college students preparing for GK rounds, quiz club members, and anyone who enjoys science trivia. Many questions also link a scientist to an invention or discovery, so it doubles as a quiz on scientists and inventions. Every answer comes with a short explanation that adds a date or a story, which makes the facts easier to remember.

Play it once for a score, then open the answer key below to read all the scientists quiz questions and answers together. Teachers can use it as a quick classroom round: read each question aloud, let teams pick an option, and use the explanations to start a short discussion.

A fun fact to take away: Marie Curie is still the only person to have won Nobel Prizes in two different sciences, physics in 1903 and chemistry in 1911. Her daughter Irene Joliot-Curie also went on to win a Nobel Prize in Chemistry.
