Re: archaeology

the pyramids of Norway, man made or not? I am going into the hidden cave to find out (the alternative is to sit inside scared at home and watch Indiana Jones on TV, eat potato chips and wait for the mandatory vaccine).

Re: Stupid question of the day

"Is [$]\Box[$] not a bit silly?" at least it makes it harder for fresh young students (like me) to understand connections between different papers. One read one paper with  \(\frac{\partial^2 }{\partial t^2}-\frac{\partial^2}{\partial x^2}-\frac{\partial^2}{\partial y^2}-\frac{\partial^2}{\partial z...

Re: Stupid question of the day

I thought heart operator is a name "students" would actually remember ;-) (one student so far = me), not fancy but practical!  It is an operation, on the very heart of physics, space and time. "Mathemticians use \(\Delta\) instead of [$]\nabla^2[$]".  good they like to be compact! so do I, so heart ...

Re: norway

" Do you have canals in Oslo?" yes they have built several short ones in the fancy waterfront areas. What does floor space cost per [$]m^2[$]? just standard canal price I think,   91 078  kr per m^2  (+ buyers gov tax)  actually that is not in the new FANCY area, this is budget canal. the new James...

Re: Philosophy As A Way of Life

In 2020 I hope to have a book published a called 'On Nature' that clarifies the Greek thinker Herakleitos (also in relation to Parmenides). This book is an introduction to my 'Opus Magnum' and introduces a more primordial theory on time and thus ontology. It will solve all problems in philosophy. w...

Re: Philosophy of Mathematics

" No way, p ~ 1.4142 cannot be a probability unless  you try to change the rules like Feynman." I disagree with F on negative probabilities, but why could we not introduce in discrete observations framework, that 5.4142 represent an expectation of for sure 5 events with 100% probability and one even...

Re: Philosophy of Mathematics

the world is discrete, so sqrt 2 cannot exist physically ? it is a probability = in the head of mathematicians, and a very good approximation in the macroscopic world !! Weyl tile Sqrt(2) is a number, not a probability. sure, my point was simply that sqrt 2 possibly not has an observable parallel i...
