Jared Duker Lichtman, 26, has proved a longstanding conjecture relating prime numbers to a broad class of “primitive” sets. To his adviser, it came as a “complete shock.” Read more at quantamagazine.org. Music is “Thought Bot” by Audionautix.
The second law of thermodynamics is among the most sacred in all of science, but it has always rested on 19th century arguments about probability. New arguments trace its true source to the flows of quantum information. Read more at quantamagazine.org . Music is “Pulse” by Geographer.
Robots are about to venture into the sunless depths of lunar craters to investigate ancient water ice trapped there, while remote studies find hints about how water arrives on rocky worlds. Read more and explore infographics at quantamagazine.org .
