Quantum Quotes

“the next”
― Jim Al-Khalili, Quantum: A Guide For The Perplexed

“During the first decade of the century, Rutherford was able to show that the Earth’s crust had to be billions of years old. He did this by measuring the amount of helium trapped inside rock samples, in which tiny amounts of uranium ore had slowly been emitting alpha particles ever since the rocks had been formed. Each alpha particle would be trapped by the rock and would quickly acquire a couple of electrons to become a helium atom. Such simple yet irrefutable proof one hundred years ago that our planet had to be more than a billion years old is something which those who subscribe to the notion of creationism are unable to challenge with any credibility.”
