Why can’t position and momentum both be precisely known? The uncertainty principle explained with the formula, a simple proof, and real-world consequences.
Nuclear binding energy = mass defect × c². Binding energy per nucleon curve peaks at iron-56. Mass defect calculations, why fission and fusion release energy, 4 worked examples.
