Ah yes - Hugh Everett. I've cited the Everett-Wheeler metatheory of Quantum Mechanics a few times in the Drawing Room thread "Is there a God?" I don't think many people understand it - you're not alone.


It's not really about parallel universes either. Bryce DeWitt called it the "many-worlds" interpretation, a more popular but still vague description of what is probably the most remarkable, mind-boggling and thought-provoking scientific theory ever proposed.

Thank you Katie - I was wondering how one might explain Hugh Everett?s meta-theory to a lay audience. Here are a couple of (admittedly, simplistic) analogies based on the two principal interpretations of Quantum Mechanics.


According to the Copenhagen Interpretation: an "Observer" in a quantum car would travel along all possible routes to every possible destination but would only "exist" at the single destination where the car crashes into something (i.e. the wave function collapses).


According to Hugh Everett's Interpretation: an "Observer" in a quantum car would travel along all possible routes and would come to "exist" at every possible destination as a superposition of his original self, with each of those selves having no knowledge of any of the other selves (i.e. the wave function does not collapse - the universe bifurcates).


Life, the universe and everything - it doesn?t get much weirder than that!

Hmmmm...purposeful and cunning misconstruction aside...I am surprised that an erudite programmable machine such as yourself should declare such a thing. May I suggest that, on this occasion at least, your - usually - rational thought has become clouded by that feisty temperament of yours.


My life has taken many directions in an immeasurable number of branching universes. Indeed, it will not have escaped your notice that at the last point of bifurcation - i.e. in this fork of the universe - I was destined to be a "staffie". As you know, each branch will have embarked on a different future completely independently of each other. As you - yourself - have alluded to above, under Everett's interpretation "I" will have come to "exist" at every possible destination as a superposition of [my] original self, with each of those selves having no knowledge of any of the other selves.


Therefore, whereas I may have been aware of the correct grammatical usage of "complimentary/complementary" whilst in a superposition in location X, it does not necessarily follow that I should then be similarly aware whilst in a superposition in an altogether different location - e.g. location Y.


However, I'm sure, you knew that.

STILL laughing BTW:))

Erm...shd I have put a smile thing at the end of my cars, mechanics. Is any of this thread relative, ha ha? that's in italics btw ;)


Anyway...did you hear the one about two electrons sitting on a park bench? No? Good, I'll leave it there then...


*goes back to reading 'bluffers guide to super-string theory'*


And at the same time..


*still laughing in another dimension*


And..

pssstt...


pssstt...Katie...


*whispers so HAL9000 cannot hear*


It's all on Google...but don't say nuffink...cos HAL9000 finks me is clever innit...


Anyway, I'm just on my way out...intend grabbing a scoop of SCIC(TM)...shall I have an extra scoop on your behalf?



*tiptoes away everso quietly*


BTW, Quantum Mechanics = Quantum Cars...love it!! Utterly logical!(tu)

Executed with due care and diligence.


Hopefully the information has now branched off to a parallel universe where it's interpretation will result in an entirely different outcome to our ?universe and where computers are now extinct. Indeed, computers have been replaced by Quantum Cars. I only pray that a superposition "Scoop" is in existence in readiness for the arrival of our superpositions.


I therefore hope to meet your superposition at Location X^/>Y in due course.


Laters.

    • Thank you both. Inexperience Landlord trying to save  a few pennies - hence no agent involved. The issue is the fact that it is my understanding that without an EPC that is current then they should not have rented the property - far  more to the point and taken rent from me. They commissioned an EPC 4 weeks & I am still waiting for or a copy!!! No gas in property. Well I guess it will be a case of instructing solicitors which I have tried to avoid doing but as they are not responding at all, I have no choice. If I am correct about EPC then it will cost them alot more than refunding me my rent.            
    • Went there a couple of weeks ago and had their set lunch menu - very good value and generous portions. Sea bream was delicious .
    • Some years ago, one of our dogs ate something dropped by rubbish bins outside a local café and haemorrhaged. Rushed to emergency vet in Streatham, who suggested that someone, worried about rats getting into rubbish bins may have put down poison. Our dog died the next day. Consequently, any dog we had afterwards wore a muzzle to stop them picking up food.
    • They have been awful for years. I moved ages ago.
