Hey Abi!
Nice to read something from you. It was indeed a long time. I have nothing to really say, as usual, as this is very far from what I do ni my everyday's life. I may however ask a little joke-ish question: what is a real ghost? :D
Anyways, I am looking forward to your return! I hope things are all good in Portugal!
Oh @lemouth ❤️
Thank you for the warm comment.
What Is a real ghost?! 😂 Well, I don’t believe in ghosts ...
But, because so many people made a comment about it I now feel compelled to write about “ghosts” here on my blog! 😃
All the best to you & take care during your travels :)
But ghosts exist! Take for instance quantum chromodynamics (the quantum theory of the strong interactions). There are several ways to do any calculation, and one of them allows to introduce non-physical stuff in the calculations in order to simplify them. But then, one needs to remove those unphysical components at the end of the day. This is achieved by means of ghost contributions...
[I over simplified it but I feel this is still tough to get :p]
Here are our ghosts, special quantum fields. Ok, I agree this is not what anyone who may think about :D
Quantum chromodynamics? I was thinking of something more in the lines of Anton’s syndrome, psychotic episodes, halluciantions etc... to explain ghosts 😅
Oh by the way, you have failed at simplifying that 😛
No time to succeed and no blackboard. Hard to explain without equations. This is terribly technical :D
