Hiya Joe, What would be your thoughts on why the human brain is much more intelligent than it needs to be for us to survive? It's just keeps me wondering what is nature trying to make us humans do? Any ideas where i can research this type of question? Thanks
This video is actually the most explanatory of the different articles etc. I've come across on constructor theory. At least you understand what David Deutsch is trying to do. He's trying to recast fundamental physics from the perspective of information and computationally theory, theories that fundamental physics has so far had a hard time dealing with.
One of the reasons this video makes sense is because it gives a history of how the ideas behind constructor theory came about. A good way to learn about a field of science, is through its history! Other articles haven't done this.
Great talk and a very interesting theory. I graduated in Physics in the 70's and looks like I may have to go back to school. Since when is thermodynamics not part of fundamental physics , aren't most laws immergent ? My mother was a Boswell but they left UK in the 1630's -
I had commented before that I was confused about why the initial state of a physical system corresponds to the program of some computer program - I thought the initial state corresponded to the input *to* the computer program and the laws of motion corresponded to *the program*. But the initial state actually does correspond to the program (because it has to be presented on a memory substrate to the computer to be manipulated by the CPU), and the laws of motion correspond to the basic instruction set I guess?
Wow, so I realized that every instruction set is a virtual reality environment - it is an environment that can execute recipes as recursive programs that bottom out in that environment's elementary tasks.
I keep wondering about this, but, would a universal computer need to have the ability to compute sets whose cardinality is infinite ? // if the 2nd axiom of thermodynamics is used to constrain the possible dynamical systems for constructors, and if the resultant set is still an infinite set (and thus the universe of possibilities is also infinite, being a superset), it would imply that the effect of such axioms (which produce infinite sets) is computable // it can also be composed with further axioms, such as to be further constrained or extended in the sense of what is possible or not
Deutsch says @ 12:06 that "possible and impossible have to be universal concepts" and that this means (he says @12:02) that "P & I" cannot occur just once but must be generalized and generalizable. This intrigues me, and forces me to ask...WHY is it that a possible thing must occur more than just once? (i.e. what causes...i.e. what forces...that to be a fact?). It's interesting to me, because that was a conclusion I came to in a theological thought experiment I conducted a couple of years ago. I concluded that "a thing can be unique" or "a thing can be replicated numerous times", it wasn't possible for a thing to be replicated ONLY ONCE. That seemed logical to me, but I couldn't clearly articulate exactly why. Deutsch's comments above draw attention to this phenomenon, so I am curious WHY he says that "a possible thing must occur more than just once".
You could say this: there are many universes in the multiverse, but only one Hilbert Space is required to describe them-- one Hilbert Space to bind them all, so to speak. Therefore all possible universes are such that Hilbert Space formalism "works" within those universes. No other can exist. Having said that, is the statement true?
What is Constructor theory? It's a theory that looks at what is possible/impossible to compute in a universal quantum computer and then states the physical laws of the universe emerge from these possible computations.
If you’re a physicist and you’re watching this video please share your opinion on my question. I am not the best at math I would probably say it’s my weakest subject. However I’ve always been since I can remember very analytical, and naturally I’ve always viewed things using “5 whys” Analysis. I’m never satisfied with the response. I always want to know more, the why, the how behind everything. I’m extremely attracted to critical thinking / first principles. For most of my life I didn’t know there was a definition to how I think. Should someone like myself even bother taking on a career in physics if I won’t be able to do the equations? I also know there many disciplines within physics. After reading what you read which discipline within physics would best suit me? I’m also into chemistry, in particular precision fermentation. I love science, but my lack of math has kept me away.
Hello, David, there is at the moment a tremendous addition, a parallelisation, a detailing of what is traditionally attributed only to entropy. It is the complexity hypothesis set in motion by Leonard Susskind. So, is there anything to consider?
Trying to frame what is possible and what isn't, in this universe, into a computational picture isn't especially "anthropic" in itself. But they haven't provided HOW these "constructors" are constructed. Experimentally? Theoretically? Using what theories? Will it follow the correspondence principle? No idea whatsoever
@@abhijithcpreej "But they haven't provided HOW these "constructors" are constructed. Experimentally? Theoretically? Using what theories? Will it follow the correspondence principle? No idea whatsoever" I have the same questions. It seems like eschewing experimentation would doom it.
The capacity of "simulating any other physical system" phrase is predicated on the access to INFINITE resources. Why is this? Because physical systems are computationally intractable by finite computational steps, i.e. with access to finite memory and time resources. This kind of mistake makes be a bit skeptical of Deutsch's class about Constructor theory. :-(
I think there is a finiteness that is relevant to what Deutsch is getting at, namely the length of the program. We know that even with infinite memory and running forever, there are non computable functions if the program has to be finite in length. Since his constructor theory involves distinguishing possible and impossible tasks to arbitrarily high degrees of accuracy, the more time and memory the better, but we know that even with infinite amounts of both there are intractable tasks as you say-as long as we have to use finite programs.

It should be called DESTRUCTIVE THEORY. If the 2nd law of thermodynamics is true and we are fairly sure that in the future at the end of time everything will eventually disappear . How can it be called CONSTRUCTION THEORY?
*Constructor theory is actually attempting to explain the origins of information* “In the beginning was the word” or, “in the beginning was information” . The question now becomes; what’s the source of information? Information is a process of selection that is, What can and what cannot be, is the same as, What’s allowed and what disallowed (setting up the rules/law) it is a process of selection, It’s also central to the process of design or engineering. Engineering is a top down process which is only generated in a mind.

For all things were created (designed) Selected to be! *God the elephant in the room that is denied!*
In essence, doesn't the Constructor Theory embrace this Oliver Wendell Holmes statement: There are one-story intellects, two-story intellects, and three-story intellects. All fact collectors who have no aim beyond their facts are one-story men. [Dynamic Law Theorists] Two-story men compare, reason, generalize, using the labor of fact collectors as their own. [Quantum Law Theorists] Three-story men idealize, imagine, predict-their best illumination comes from above the skylight. [Constructor Theorists]
Yes in a senses. But I don’t think constructor theory has been developed enough to be able to test adequately for its validity. So it is a the moment not a science. Just a thought experiment that cannot be tested.
Constructor theory has a bad ring to it, for my cultivated eye, to say the least. First, ”constructor” theory, the title, sounds unfortunate, simply a mishit, a failure. And if it is a fitting, succint ”description” of the theory the theory gets downgraded to a work of an engineer, not a bona fide theoretician, be the engineer a human mind or a machine, quantum or mechanical. This last note leads to the more fundamental critique of ’constructor theory’. When we reduce physical reality to computation and by the same token everything else (society and human subjects) we as a civilization have already taken the last step to a simulation society where digital rendering of what is physical, bodily, sensible, sensitive - REAL has replaced whar is real. Constructor theory - not for me. Thank you!
"...what can and can't happen." That's the theory? There seems to be no substantive explanation for this "theory". Give me something concrete, and for heaven's sake, show me the equations that models it.
On my interpretation which I used in my reply to a comment above, I think a start would be to refer you to Turing's 1936 paper on computable numbers. As I say above,
I certainly would like to see some new math, some equations illustrating his new theory. There is a lot of math in physics, so I expect something new there, and untill now he is only talking.

nobody does really think that, apart from the authors of the theory and apparently you
I think David Deutsch is cleverer than me.
Still don't understand what constructor theory is.
The laws of physics applied to the elements in space have to be computable within that space by the interaction of the elements within it.
