Heisenberg's uncertainty principle is a fundamental concept in quantum mechanics that states that certain pairs of physical properties, like position and momentum, cannot be simultaneously measured with arbitrary precision. For year 12 assignments, resources such as "Quantum" by Manjit Kumar and Wikipedia's page on the uncertainty principle are recommended for comprehensive overviews. Additional academic papers and discussions, including those by Albert Messiah and Lee Smolin, provide deeper insights into the principle's implications. Forums and lecture series by Richard Feynman may also offer accessible explanations suitable for high school students. These resources collectively help clarify the complexities of the uncertainty principle for educational purposes.
