The goal of parental authority should not be to crush the child’s will and force the child into alignment with the parent’s will. Rather, the goal should be to develop and lift up the child’s will with the child’s well-being in mind.

This title is misleading. It merely estimates the atmospheric lead concentration during the Roman era from Arctic ice core samples, then estimates blood lead levels from the atmospheric lead concentration, and finally estimates the impact on IQ from those blood lead levels.

The decline of the LCD business has led to a shift toward solar cells. I wonder how long perovskite solar cells will hold up. As for organic thin-film solar cells, it still seems tough for them to gain traction.

The Fast Multipole Method (FMM) improves the computational complexity of n-body simulations, such as particle systems, from O(N^2) to O(N). It achieves this by grouping distant particles and calculating their interactions collectively. The Japanese name for this method is "高速多重極展開法".

If video generation models advance to the point where fake videos can be created freely and indistinguishably from real ones, will images and videos lose their evidentiary value, rendering surveillance cameras meaningless? Ultimately, will it even become possible to install fake memories...?
It might not be very relevant, but I occasionally come across careless mistakes like this. I've even seen a math professor make such errors.

True, it's not as "real life" useful as the Pythagorean theorem or the solutions of differential equations, but it is part of a larger whole of understanding polynomials, and those are important. #EduSky #MathSky
It is obvious the date of the winter solstice is the same in the northern hemisphere. However, given that the Earth orbits the Sun and its rotational axis is tilted relative to the orbital plane, it seems less obvious due to the variation in the time of solar noon. en.wikipedia.org/wiki/Analemma

Why probability probably doesn’t exist (but it is useful to act like it does)
All of statistics and much of science depends on probability — an astonishing achievement, considering no one’s really sure what it is.

Recent sports radial tires tend to prioritize grip performance over durability year by year. It can't be helped, though, since lap times take precedence over durability on the circuit. > ‘The first and the last priority is always going to be safety.’
