I help look after a Trust reserve where Hazel Dormice have been reintroduced. There is Hazel coppice, that is degrading as time goes on.Which group is running this reintroduction? I assume PTES who have been releasing. They ought to be aware of the importance of habitat management for dormice.
Soooo... fields, as I've described them in my question don't actually exist and are just an easy way to describe how something in the physical world works and behaves?They donít exist in the way you think about them, but what they measure and model are real enough.
Geeze!! I was testing how to download a picture. The test was a success, but I deleted the picture. Now move along and let this meaningless post move down the list of unread posts until it disappears into the aether.There is no aether
Ps - I did not quite understand the reference towards tryin to beIs it racist to mention a general characteristic of a nation or group? Not sure whether we do talk about the weather more than other nations, but we have a lot to talk about in the local weather:
" BRITISH " .
I Strongly Object Racism.
(Are you trying to be a Racist?)
You seem to me to be be saying or implying that ,if measurements were finer and more efficient that the position and the momentum of a particle could be determined separately and not as a pair that are joined at the hipNo, Iím not saying that, as Alan has explained very clearly.
Iím not aware of one either. I think this is a misinterpretation of the solution to some wave equations where there is equal probability of 2 or even 4 solutions; that doesnít mean those solutions exist simultaneously.I often read that particles can be in two separate locations at once.This has certainly never been demonstrated, and while not denying it, I am unaware of a quantum interpretation which goes to far as to assert this.
Agreed, itís a common misunderstanding of the SchrŲdingerís thought experiment.It is when I read that 'a particle' can be in two separate locations at once I wonder if the statement is true and if it is at all helpful to describe it as such when discussing superposition?A cat being in superposition of dead and alive is not the same as saying it is both dead and alive. I think that's the disconnect not spelled out well in statements that word it otherwise.
(Let's just Forgive & Forget & move on...bcoz they certainly do not know, what they are doin)Agreed, let's leave this thread as quickly as the OP left.
All women need to be impregnated immediately by men who show natural resistance to the lethal covid disease,As women have a stronger immune response than men and men are more likely to die from covid, it may be the other way round. Look for the women who had very few symptoms?
I Agree with the Simulation Hypothesis.Not our doing. Curious, furious, billy is playing some odd self pleasing game.
But i find it Futile to respond to your OPs.
Considering they will be Gone Away with the Winds.
more of like from Knockin on Heaven's Doors.Guns version was very good, Dylan is one of my favourites, and Dylan + Knofler is well worth hearing. Raign version very atmospheric, used on Ď100í and ĎSons of Anarchyí. Clapton version is a classic. One of the fascinating things about Dylanís songs is how they inspire very different arrangements, very few are straight covers.
But for those who have indicated the possibility of this being the case, have they or do they need to take into consideration what happens to 'me' and our universe before relativity, at the uncertain quantum level?Not sure how relativity would come into it, but if you donít know of their existence then it would be impossible to take into account what happens to them.
The idea of Spam is that the canning process has anti-aging properties for the Spam - mod.I believe the frying process also releases extra anti-agens, particularly if deep fried in batter. It also helps if you sing along as you fry 🎶spam, spam, spam, spam🎶
However, with time, this virus started to show less and less symptoms, until it became almost completely harmless to rabbits.This is rubbish.
You know, it's funny. I LITERALLY just had an online chat with a cosmologist yesterday evening and one of the things he said to me was that matter, as we currently know it, may not actually exist at all. Fields exist, and particles such as Protons, Neutrons and Electrons are merely excitations of those fieldsI agree with @Halc on this, but I think you need to sit down and think what you mean by the word exists.
At any rate though, I do understand most of what you're saying. Mostly that we have very little idea what light actually is.Actually we we know a great deal about what light is, how it works etc. It is another of those ďmerelyĒ excitations of a field, and that means we can understand it in ways we couldnít before.
The next important thing is that you have probably read or been taught that momentum = mass x velocity. This is probably why you are concerned about the photon having 0 mass but still having a non-zero momentum.I may be misreading what you say, but it implies that relativistic mass was Ďdevelopedí in response to the Ďrest massí of the photon being zero, and hence to maintain the concept of momentum for the photon.
There are at least two ways we can address this issue. The first is to say that many physicists were also troubled about this. It's a very good question to ask and something that does seem quite puzzling.
Physicist's were sufficiently determined to maintain this simple concept of momentum that they developed a quantity called "relativistic mass". They accepted that the invariant mass of a photon wasn't anything you could ever really measure, it certainly wasn't going to be measured as the mass of the particle when it was at rest in some inertial frame. So they determined that the invariant mass wasn't something that should be used in that formula momentum = mv.
........I thought perhaps I would email some private dermatologists or find one where I can present this as clearly as possible.That sounds a good way forward, but they are going to be interested in appearance (photos) and symptoms (eg itch). They might suggest skin sample for analysis, but this is a specialist job for a lab as they are looking for more than microorganisms.
Perhaps the surface has something to do with it.Dishwashers (including me when I do them by hand) rely on retained heat to do the final drying. Glass & ceramics retain heat, plastics donít.
Maybe Plastic ain't as smooth as Others.
"Can space ever be described as empty when the electrostatic field of oscillations is always active allowing us to perceive the history of our universe?"Well Ron, you are right that the electromagnetic field is continually active in the form of light, radio waves including microwaves etc and these fill space.
Thanks very much.I know you deserve a response to your reply but I feel embarrassed to spell out what I was thinking as it might seem that I was trying to back up my opinions.(or that I understood what I was saying;) )No need to feel embarrassed, itís just a case of my wanting to clarify what you were looking for.
But just to attemt to clarify the point you were asking directly,I had in mind that there might be a discreteness at levels unattainable of detection either practical or theoretical such that we would have to simply assume it to be the more likely case out of intellectual preference (if such a concept is valid).
I guess I just anticipate that it will be entirely impossible to find evidence one way or the other but you seem to be suggesting that evan_au 's link contains an avenue of attack that may bear fruit at some stage.(I had better attempt to have a look at it even it is probably too hard for me to understand)
Not sure what this has to do with the continuity of spacetime, but:It was in response to a question from geordief ďIf we postulate continuity of spacetime at the finest detail it seems to me that that may pose more problems than to postulate discretenessĒ and I assumed he was drawing a parallel between quantum world and spacetime, I was just pointing out that not all the quantum world is discrete.
Even then, the energy is frame dependent and probably expressed in the proper frame of the atom, which is becoming complex enough to have a classic property like KE.I agree that the the KE is frame dependent, but that frame is not relative to the atom for a free electron that is not bound to the atom or part of a metal lattice, say, itís usual to take the frame of the particle accelerator, or even a crt.
I have a rough time giving KE to a free electron when (per Heisenberg uncertainty) such a thing doesn't really have a velocity until measured, and that measurement does not preserve the velocity, so you only know what it was, not what it is. For the same reason, it doesn't have a location, and it having neither of these properties kind of puts a dent in the model of continuous spacetime.
