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.
The Power of Adults Over Children: Oppressive or Liberative?
Adults can use their power over children in either oppressive or liberative ways.

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 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.
