Quantum entanglement’s long journey from ‘spooky’ to law of nature: Quantum mechanics has always included mind-bending ideas. But the concept of quantum entanglement, famously termed “spooky at a distance” by Albert Einstein in a 1947 letter, seemed to challenge the limits of belief. It remained well on the edges... by Knowable

Scientists warned about climate change in 1965. Nothing was done.: A key report to President Lyndon B. Johnson in 1965 warned that humankind was “unwittingly conducting a vast geophysical experiment” through the burning of fossil fuels and a consequent buildup of “the invisible pollutant” — carbon dioxide... by Knowable
