Question 1

True or false: Planck's famous constant, h, was derived from studying blackbody radiation.

Accepted Answer

True. In 1900, Planck introduced h to solve the ultraviolet catastrophe, founding quantum theory.

Question 2

True or false: Planck was awarded the Nobel Prize in Physics in 1918 for his discovery of energy quanta.

Accepted Answer

True. He won the 1918 Nobel (awarded 1919) for his quantum theory, though many initially doubted it.

Question 3

True or false: Max Planck originally wanted to become a professional pianist before switching to physics.

Accepted Answer

True. Planck was a gifted pianist and nearly chose music over science, but a professor convinced him physics offered more depth.

Question 4

True or false: Planck discovered the photoelectric effect before Einstein.

Accepted Answer

False. Einstein explained the photoelectric effect in 1905 using Planck’s quantum concept; Planck himself did not work on it.

Question 5

True or false: Planck's constant is the smallest possible unit of energy in the universe.

Accepted Answer

False. Planck’s constant is a proportionality factor, not an energy unit; the smallest energy depends on frequency and context.

Question 6

True or false: Planck’s second son, Erwin, was executed by the Nazis for involvement in the July 20 plot.

Accepted Answer

True. Erwin Planck was executed in 1945 for his role in the conspiracy to assassinate Hitler, devastating Max.

Question 7

True or false: Planck personally opposed Einstein's theory of relativity for decades.

Accepted Answer

False. Planck was an early supporter of Einstein’s relativity, helping to promote it and hiring Einstein in Berlin.

Question 8

True or false: Max Planck was forced to resign his academic post during the Nazi regime.

Accepted Answer

False. Planck remained in Germany and tried to protect Jewish scientists, but he kept his position until 1943, resigning due to age, not force.
