Part 2/11:
The journey into the oddities of quantum mechanics traces back to a seemingly common object: the light bulb. Back in 1900, German engineers sought to perfect the light bulb's filament, unaware that their quest would provoke a scientific revolution. The bond between temperature and the filament's color was a mystery that puzzled them. To unravel it, the help of physicist Max Planck was enlisted, leading to groundbreaking revelations about energy and light.
