Chalmers in point 2 is not saying to imagine such a world, but that such a world is logically possible. Chalmers gives as an example of a logical impossibility a male vixen since it is contradictory. He states "... a…
To illustrate what can be done with the BOSL2 library for openscad this can add 3 "diamonds" to the RIGHT, FWD, and TOP direction of a square, with the RIGHT and FWD diamond's corner touching the square on the side and…
Another option is the BOSL2 library for openscad which has align, attach and anchor operations and many other useful operations and parts.
In the case of sunlight exposure to UVB an equilibrium is reached where the amount vitamin D produced in the skin equals the amount destroyed by UVB. This does not happen if you pop vitamin D pills. I've recently…
This was about 10 years ago but here in New Zealand I found someone who could repair and replace the rubber so my 30 year old infinities are as good as new.
The tiling window manager in popOS is well thought out, has intuitive key bindings. As a former i3wm user I find it a significantly better.
The light that is required to increase vitamin D production is UVB. The Penn State researchers used a pulsed UVB source for their research. Lower frequency light will not activate the conversion to vitamin D. Glass…
The problem here is that UVB levels, required for vitamin D synthesis, decrease dramatically before 9am and after 6pm, whereas UVA does not. The best option for vitamin D synthesis is short sun exposure around midday.
