What if Marie Curie had patented radium? She deliberately refused, believing science belonged to everyone. A single gram was worth $100,000 in 1921. She lived in poverty while others made fortunes from her discovery.

Marie Curie and Pierre made a conscious decision not to patent the radium isolation process. They published everything openly. Meanwhile, radium became one of the most valuable substances on Earth — used in medicine, industry, and even consumer products (radium watches, radium water, radium toothpaste).

If she had patented it, she would have been one of the wealthiest people in Europe. Instead, she worked in a leaking shed for four years, raised two daughters on a modest salary, and donated her Nobel Prize money to the French war effort.

Some argue the decision accelerated radium research worldwide. Others say it left her vulnerable — she couldn't even afford a proper laboratory until Andrew Carnegie funded one.

The deeper question: would nuclear physics have developed differently if radium research had been locked behind patents?
