Re: How many elephants ...


It’s not a trick question? Why would you ask then? I find this disturbing.
I thought finding #10 was tricky. Of course, now that I've said how many, it's spoiled.

Re: How should we deal with the coronavirus pandemic?

Do you know if the cause of the relative vitamin D deficiency in non-Western immigrants is genetic, behavioral and/or diet related? I dont know, but very likely a mix of these. More protected agains UVB as genetically from areas with much more sun exposure (warmer so show more skin etc.), and there...

Elefanten i rommet – vitamin D og korona blant innvandrere

"Faktisk har norske helsemyndigheter alt i forkant av pandemien vært kjent med at det er betydelig mer vitamin D-mangel blant ikke-Svestlige innvandrere. Dette kommer klart fram av en rapport utgitt av Helsedirektoratet i 2018"

Re: New Clock Synchronization Gedanken Experiment

"Kassner tries to justify the discontinuity by introducing the unusual concept of a ‘time gap’ and states that ‘the speed of light is c everywhere except at the point on the circle where we put the time gap " This is as we have mentioned an unphysical time-gap. Standard theory could need t...

Re: negative transition probability

"With this all in place, if the single gravitating atom demonstrates the key ingredient needed for quantum computation, which is curiously associated with "negative probability," nature must take the quantum gravity approach." https://www.sciencedaily.com/releases/2021/02/2102171...
