“Since the Egyptian scribe Ahmes put pen to papyrus some time around 1550BC to explain how to calculate the slope of a pyramid, we’ve had over three millennia of maths literature. So within some level of statistical confidence: here are a subset of the best ever maths books.”
@actuallyautistic#actuallyautistic Somehow got into an argument earlier about fractions with my parents, especially the fraction 15/16. I said that 7.5/8 is the same thing as 15/16, because they can be converted to each other by multiplying or dividing the numerator and denominator by 2.
My mom basically said, no, that's not right because it's not a "proper fraction" which doesn't make sense to me. The math checks out, and numerators can have decimal integers. Is there something I'm missing?
Mathematicians Attempt to Glimpse Past the Big Bang
“Researchers already knew that in a universe with so-called dark energy, but without matter, the start of inflation identified in the BGV theorem is a coordinate singularity that can be eliminated. But the real universe has matter, of course. Might mathematical tricks also make it possible to get around its singularity? The researchers showed that if the amount of matter is negligible compared to the amount of dark energy, then the singularity can be eliminated.”
