Same objection as that by Stuart applies of course in the case of simplest particles as 1-bit objects. After all, there is no way to know the lower bound necessary for nature to startup and the only way for this would be to find an exact match with a generic automaton or network of automata that perfectly mimic actual phenomena. This then brings about the totally "infamous" Zuse-Fredkin-Wolfram Conjecture which is nothing but a rather contrived version of the old Church - Turing Thesis. (Infamous because after 2000 people associated it with "Simulationists" arguments like Bostrom and others.) Too much water has run on this mill from the 60s onwards without any clear result but there were some very interesting attempts that have now been largely forgotten. For instance, who remembers nowadays the work by Pierre Noyes on the combinatorial hierarchy?<br />https://en.wikipedia.org/wiki/Combinatorial_hierarchy<br />https://en.wikipedia.org/wiki/Bit-string_physics<br />Even worse, there are things that have been swept under the carpet like the isomorphism of certain dualities and concurrencies with the algebraic structure of QM, first shown by Vaughan Pratt with the aid of some rather deep categorical mathematics in "Chu Spaces".<br />http://chu.stanford.edu/guide.html<br />So the quest continues but the true reason for my previous comment is the existence of analog encodings which are equally good with "binary" ones and hence they put into trouble all this talk about an absolute distinction between "discrete" and "continuous". In fact, what I find unnerving is how much (bad) engineering (say "Gates" or just "It's-Better-Manually") may become an evil influence for physicists. Once I met a blog article by a "stringy" theorist who was beating down two guys by bringing in their face a 1961 paper by Landauer claiming that his principle should be promoted to an axiom of nature. I could not conceive of a biggest misdirection given that there are already various methods for reversible computing. But that's not the worse. Recently they managed to do it with just "schmutzdecke"! <br />https://www.elsevier.com/about/press-releases/research-and-journals/computing-with-slime<br />So, the one thing I would need to know is the encoding, the basis of everything else.Theophanes Raptishttps://www.blogger.com/profile/01269614280130174555noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-37216273627795921162016-04-29T14:25:09.595-07:002016-04-29T14:25:09.595-07:00Stuart: Good comment.

Ideally, this appears to require at least some binary medium. In such a medium any deletion/erasure act would invoke Landauer's Principle on irreversibility thus raising the entropy of the medium. But there are more tricky ways to store information in analog media via Fourier encodings. So, the exact storage mechanism here does matter.Theophanes Raptishttps://www.blogger.com/profile/01269614280130174555noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-84082042970882834752016-04-20T22:28:54.194-07:002016-04-20T22:28:54.194-07:00Wouldn't the proposed "information deleti...Wouldn't the proposed "information deletion" violate the quantum no-deleting theorem ?Unknownhttps://www.blogger.com/profile/17066011884614465783noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-77838760417853177302016-04-13T01:12:28.427-07:002016-04-13T01:12:28.427-07:00Hi Duane.

There have been far, FAR too many frauds and charlatans on that path. Jim Woodward's method wrt his "Mach Effect Thrusters" is a much better way to build quiet credibility - make limited predictions, no promises, adhere strictly to the scientific method, open the books at all times so that anyone can examine your procedures and database. And do as much as possible in test-stand hardware; show tangible results, not the kind of mathematized navel-gazing metaphysical pseudo-philosophy that produced dark energy and dark matter to begin with.

Let's see, the Diamond Light Source has electrons travelling close to c, in a ring 89m in radius, so (forgetting about the corners for now) it accelerates at about 10^15 m/s^2 so the Unruh waves should shorten to a tractable 720 m and they'll be different from the synchrotron radiation. These waves will only be seen by the electrons, not us, but if we take account of relativity, and apply radio waves of the right wavelength so that in the electrons frame of ref' they're 720m long, then we could damp the em-component of the electrons' Unruh waves, and change their inertia. This'll have to be calculated for the vertices of the polygon: the acceleration will be higher there.Mike McCullochhttps://www.blogger.com/profile/00985573443686082382noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-2030685788354674532016-04-12T03:51:30.211-07:002016-04-12T03:51:30.211-07:00Would the Unruh radiation be easily distinguishabl...Would the Unruh radiation be easily distinguishable from the normal synchrotron radiation?

Usually MiHsC shows itself at very low acceleration, but I published a nice CERN test for MiHsC a few years ago (see EPL, 90, 29001, 2010). The idea is that the LHC can accelerate objects so fast that the Unruh radiation the objects see, which is usually light years in wavelength, becomes short wavelength enough to be interfered with by our technology (eg: very long radio waves). Can we modify a particle's inertia electromagnetically? I gave a talk on that up in St Andrews a while ago.Mike McCullochhttps://www.blogger.com/profile/00985573443686082382noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-85726511909030548482016-04-12T02:02:46.762-07:002016-04-12T02:02:46.762-07:00As for the multi-billion-dollar thing, it does ind...As for the multi-billion-dollar thing, it does indeed seem that dark matter would be a lot less popular without the LHC, which holds out the possibility of finding Something Odd which the DM theorists can latch onto. If LHC reaches its design energy without finding Something Odd - and indeed potentially excluding a number of the simpler DM candidates - we may see a wave of restructuring pass through the theoretical community. Or if it does find Something Odd, at least we'll have something to navigate by.<br />Heh. What should we be looking for in the LHC data to validate MiHsC? :)AdamWhttps://www.blogger.com/profile/06729190099956182183noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-78786595986286907232016-04-12T01:55:53.771-07:002016-04-12T01:55:53.771-07:00For the hard-of-thinking, can you use this approac...For the hard-of-thinking, can you use this approach to explain the EM-drive results?AdamWhttps://www.blogger.com/profile/06729190099956182183noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-45644424308669613492016-04-10T08:10:56.679-07:002016-04-10T08:10:56.679-07:00Maybe I should emphasise that MiHsC is a potential...Maybe I should emphasise that MiHsC is a potential new source of energy, get the oil companies mad at me, and then reap the sympathy vote? :)Mike McCullochhttps://www.blogger.com/profile/00985573443686082382noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-59495493188250872062016-04-10T07:00:16.805-07:002016-04-10T07:00:16.805-07:00Find an expensive experiment for MiHsC? :)Find an expensive experiment for MiHsC? :)Czekohttps://www.blogger.com/profile/04231020181834141834noreply@blogger.comtag:blogger.com,1999:blog-4637778157419388168.post-36153844030219737272016-04-10T03:22:16.970-07:002016-04-10T03:22:16.970-07:00Yesterday I received an interesting email from Rob...Yesterday I received an interesting email from Robert Ludwick, so with his permission I reproduce it here:<br /><br />"Hi Dr. McCulloch,<br /><br />Please excuse my use of email instead replying on the blog in the normal fashion, as I have no ‘identity’ acceptable to the reply filter.
