The idea that a popular science book by a reputable physicist has no value seems to me to be preposterous. Are you saying that we cannot learn anything from such books? Einstein wrote a popular science book on Relativity and explained it really well. The link you sent me explains Carrolls view...

David Deutsch is a well known proponent of the Many Worlds Interpretation. His argument seems to be that a single photon in the double slit experiment must be interfering with one from another world. It is commonly held by physicists that the the photon, as a wave going through double slits, can...

Regarding the continuum of universes. Maybe Deutsch is referring to his hypothesis that all the universes interfere with each other in quantum experiments. Also, he could mean that you would have a continuum of universes where one differs from the next by the smallest degree. It is hard to pin...

Firstly, it is no way obvious how to post a question on this forum. I have only found out how to make a reply. David Deutsch is a well known proponent of the Many Worlds Interpretation. His argument seems to be that a single photon in the double slit experiment must be interfering with one from...

That is roughly what I thought, but Rovelli in his popular books is very confusing. I am waiting for a negative review. You could of course have quantum effects have a real purely objective probabalistic effect on the world by putting the likes of Donald Trump in Schrödinger's box instead of a cat.

I agree, but in regards to the temperature of a cake, Rovelli maintains that the there is entanglement between the cake and a thermometer stuck in it. This is a classical situation. He is very confusing.

Yes, of course, but apart from such situations. Is there interference and superposition when I am about to open the door of the bedroom to see if my wife is inside, or in any other situations that might be described as classical. I do not think so, but after reading Rovelli's Helgoland, I am not...

I don't know if you have read Covelli's book Helgoland. It is very confusing that he uses the example of Schrödinger's cat. The simplest way of approaching SC is to hold that collapse occurs in the geiger counter (and Rovelli emphasises that a conscious observer is not required). In this case it...

Yes of course, but I was talking about the macro-world. We do not for example see interference when I go into a room to see if my dog is there. I have great respect for the double slit experiment, but only here do we see interference. Thanks for you reply Peter.

Sorry Frederik, you already have given your objections to Rovelli in terms of symmetry. But there are many simpler objections such as his treatment of Shrodingers cat. Are we to say that the superposition continues in an infinite sequence. And how does this differ from an every day world where...

Ok Frederik (probably from Denmark - irrelevant of course) - a very peaked probability distribution might just do it. But this cannot be empirically be verified, or more importantly, be falsified. Also he should say that the probability distribution is peaked. What please tell me what aspects of...

My question still stands. If he assumes that the same fundamental principles should be valid for both then he he must be able to identify examples of interference in the macro-word. He has actually said in Helgoland that the macro-word is also probabalistic. And this probability is not one based...

Good. Please let us know why you are not a fan of RQM.

To me the Schrödinger's cat experiment is a red herring, unless you believe that there has to be a conscious observer. The geiger counter would collapse the wave function If you include the observer and an observer of the observer, then you get into an infinite regress and introduce QM into the...
