Strange

It is nice of you to give us a preview, but which peer-reviewed journal is this being published in?

*shakes fist* I MEANT TO SAY THAT!! Can I get back to you on that... Did you know that De Morgan taught Ada Lovelace?

What evidence do you have that any such slashing of energy consumption will happen? What evidence do you have for the numbers of deaths that this will cause?

I think that Turing's contributions were very important but computers would have been developed anyway. Possibly in a more ad-hoc or experimental way in some respects. People were working on computing machines before Turing. One of his major contribution was to the theory of what it is possible to compute (which had been developed by others) by showing that a certain type of computer (a Turing machine) can solve the same problems as any physical computer. And this set of problems is exactly the same as that which can be computed by any method (the Church-Turing thesis). He also did some important work on the application of computers to information theory (algorithmic information theory). These concepts were probably important in the development of cryptography and compression algorithms, by helping to define the limits of computation and compression, and these are important to the development of the Internet.

And also explains a lot of things in embryonic development.

Well, thank you.

Interesting question. I can’t think of anything. Most of his work was theoretical, on things like “what functions does a computer need; what problems can it solve” I am not aware of anything specifically related to network connectivity. Someone who has studied CS might have more ideas.

One lesson that one can take from that article is that waves/particle/fields are not what these thing are, they are just how we describe them. The map, not the country

You cannot equate spacetime curvature with time dilation. For all the reasons that have been explained to you repeatedly and in great detail by many people over many years. As you desire to replace the Einstein Field Equations with some simplistic model based on a refractive aether, you very obviously do want to replace GR. "I don't want to replace GR, I just want it to be completely different. And give the wrong results."

That loud noise you can hear is my head hitting the table repeatedly. I give up. Have it your own way,. You are a genius. Einstein was wrong. Everyone else is blind to the simple truth. I think this thread has run its course.

One problem is the rate of change. Evolution and adaptation is a very, very slow process. If environmental change happens too fast then there is no chance to adapt. And we know that the current changes are happening faster than at at any time in the past. I find it strange that those whose political ideologies are aligned with using natural resources are so often opposed to managing those resources. I am sorry, but after Brexit (a campaign run by an elite group of billionaires and public schoolboys in politics and the media) I find accusations against "the liberal elite" ludicrous. It has become the modern "political correctness" - a pathetic and meaningless insult to throw at people who you disagree with. In what sense are academics (who are experts because they have spent their careers studying a subject) "elite"? Even if they are "liberal" (gasp!!!) they are not in charge. They provide information and advice. It is up to governments to take action. The UK has one of the most extreme right wing governments for decades. Not one of them could be described as "liberal elite"; they are just elite - rich, entitled and not terribly clever. But even they see the need for lockdown (even if a little too late so they have killed many thousands of people). You may think you are incredibly strong, brave and street-smart (none of that stupid book-learning for me, thank you very much) but viruses don't care. You might be young, white and healthy, and therefore at low risk. But your selfish desire for "personal freedom" means you would put others at risk. If you think your personal freedom is more important than other people's survival then that makes you you are the "liberal elite". Nice goalpost shifting. "If Elk are in danger; they can just move" "So what if they can't move, who cares about them anyway"

Form the article: "Now, Willner and friends have done much the same thing, but with 28GHz radio waves." Did you see that? 28 GHz. That is more than 100 MHz. And they managed a distance of 1 metre. Water is many, many times more dangerous than the signals from cellphones.

No, I’m saying there is a relationship but not a direct or necessarily simple one. I’ll work out an example... Imagine two planets with exactly the same surface gravity but where one is 10% heavier and has a 5% larger radius. There will be a slight difference in gravitational time dilation: clocks on the larger one will run about 3 billionths of a percent(*) slower (I think I've got that the right way round). So gravity and time dilation are related but not directly. (*) I really should have chosen a more extreme example, but I can't be bothered to go through it again.

Fundamental doesn't mean easily solvable. It depends how you define independent. And, perhaps, how you define "gravitational attraction" as you are equating it to spacetime curvature. They are clearly related because they have the same cause. But the usual meaning of gravitational attraction is the "force of gravity" (the acceleration due to gravity, g here on Earth). In which case, there is direct relationship between the two. You can have two places with the same value of g but different time dilation. (Or the same time dilation but very different values of g.)

What value judgement? What's in my mind? What are you talking about? It is simply false. If it is honest, then you are ignorant. I have no idea what "value judgments" you are talking about. (But you are right, your erroneous descriptions are probably off topic. So we can leave it there.)

Because engineers investigate. And scientists “carry out” (I assume you mean do/implement things, rather than get takeaway food ) It is an arbitrary and misleading distinction

No, just wrong. (And slightly disparaging to scientists and engineers.)

Yep. That is what you need to do. I am surprised you don't realise that. Maybe you could read some books / look at some videos on marketing and how to create a new business / sell your skills. Sadly, it is never as easy as just saying "Hey, I've got some skills and am available to work with you." There are plenty of other people out there with similar skills, so you need to find some way of differentiating and selling yourself. In the case of academics, they have ready access to a pool of students and technicians to help develop projects. If they need more help, and the research budget stretches to it, they may go to an outside contractor or industrial partner. But this is likely to be someone they have worked with before, or someone recommended by a colleague. I don't think academic institutions are much different, or more bureaucratic, than commercial companies. You would face similar challenges getting work with an industrial organisation. Pffft

Or look for a job as a lab technician to build contacts and experience I suspect most people who do the sort of freelance design work you are talking about, start out by doing work for their former employer(s). It can be hard to get started without a proven track record of successful projects and satisfied clients

There are a few posts with some general help at the top of this section of the forum: https://www.scienceforums.net/forum/28-suggestions-comments-and-support/ And a guide to Latex here: https://www.scienceforums.net/topic/108127-typesetting-equations-with-latex-updated/

I'm not sure what a smoke bomb is, but it sounds incompatible with the idea of trying to create a vacuum. Smoke is just fine material suspended in air. In a vacuum there is no air so you cannot have smoke. But you can have dust. So any fine material would do. It won't float about (if you have a good vacuum) but I assume that is the point: you want to know that your device is exerting a force on it, not just random air movements. One problem you might have is eliminating any static charge to avoid clumping. Lycopodium was the classic inventor's material for this sort of thing. There may well be modern alternatives. https://en.wikipedia.org/wiki/Lycopodium_powder#Other_uses

The"end" is a pressure of zero (not 30). You can get as close as you want to zero. But the closer you get the more difficult and expensive it is (because of leaks, outgassing and all the other issues mentioned in this thread). Here: Read the article at that link. It is useful

To write Latex, you need to use the [math] tags. For example: [math] n \in N [/math] Gives: [math] n \in N [/math] (Note there is a bug in the software and you will have to refresh the page to see the result) ! Moderator Note Moved to The Sandbox
