As long as they didn't copy the text then the copyright wouldn't have been infringed and there is nothing Einstein would have been able to do. During my PhD someone published an easy but rubbish version of what I was trying to demonstrate. In the end it turned out that the hard version isn't really possible with current fabrication methods. If we'd have been able to get it to work it'd have been so much better. But that's a risk you take when you make decisions like that.

If your copyright has been infringed you can sue the author and publisher. I can see the situation where you're post history here for be evidence for copyright ownership. But if they've just taken the idea and written their own work on it then there is no protection for ideas.

What's the difference between making public and publishing?

Your visual system is a complex signal processing system with a dynamic nonlinear sensor on the front of it. Your experiments do not try and control for any of this. What you've done is shown than the amount of light hitting the sensor isn't the only factor involved.

My key has a data connection with the car when it's on gh dashboard (it logs error codes). It would be an added security measure if it used that connection to also pass newly created codes. Obviously if you just unlock and then lock your car without​ using the key tool drive you'd have to rely on the old method but that would reduce the opportunities for interception.

I disagree, people have invented them. https://en.m.wikipedia.org/wiki/Flying_car_(aircraft) I'm not sure getting others to give you a list is in the spirit of the task. Think about what could make your and people you know lives easier.

But if your boundary conditions are forcing a field value the. They will alter what you measure inside the box. What package are you using? It was a few years ago but i found meep very accessible.

And the y axis is something like E^2? I'm not sure that you want dirchlet boundaries for your box. As that might give some unusual effects. I was expecting PMLs or similar. It has been 5 years...

What are your boundary conditions? Can you clarify that on the x axis it is distance from source at a given time?

And then magic happens... And it works. Just trust me it works. And then magic happens. That is how your post reads. You've not answered my questions yet. That will probably result in the thread being closed.

Ah I see. I think a third might be needed as a there's no one stood there sensor at a very low height.

Have they experimented with not flat surfaces?

Very true. I've not tried them but you can get IR lidar modules that might be a little better. You'd have a much better grasp of the angle you're measuring as well.

When i read your opening post this is the question that appeared in my mind. I was hoping it was an already built device we could see. My initial thought would be by scanning an ultrasonic distance gauge over a few angles using a servo. You can then map the space, work out whether anyone is stood there and their height. An acoustic radar, ACDAR... I was assuming the sensor system had to be on the mic stand. Really I'm not convinced this is a terribly good idea, likely to be finicky and doesn't add much value.

The guys who fitted this must get around. Climate controlled laser lab. Air movement kit on one side of the room. Thermometers on the other side right next to the femptosecond laser. You'd get in in the morning and it'd be quite pleasant. Turn the laser on and within a few minutes the air con was pushing out air right over most of the bench and where you'd want to stand to align the optics at about 3degC.

In the UK we have a stem ambassador programme which people and organisations sign up to it makes it easier for schools to just contact an organisation and get someone to come talk to them about stem. I'm not an ambassador but several of my friends are and it seems to work quite well.

I don't think it is random. Even if the exhaust exit was random how would that be an improvement on ADC random generators? You've still not addressed my questions.

Surely the thing to do is use hardware random?

Several parts of your last post can be considered "and then magic happens". "The engine will recognise an algorithm" how? Show the maths for how this can work? Thus far you've answered zero of my questions.

Do you have any evidence or mathematical model for anything you've said? Again your post is just going to create more questions. It looks very much like wishful thinking. If you want to discuss blackholes start a new thread. But you'll get very similar questions.

You're going to have to present a mathematical model for how light can act as you suggest. How can compression force light​? Your follow up post answered none of my answers and opens a lot of new questions.

How do you get the photons to travel with the exhaust gas? With tubes that small how do you account for the drag stopping the exhaust escaping efficiently and stalling the engine? Can you show some maths on how you do a calculation?

We've got open plan offices. Where I used to have my desk was outside the coverage of all of the movement detectors. Most of the time it was fine but when I was the only one there I'd have to regularly stand up to not be plunged into darkness.

The best is probably something like InSb but the band gap isn't very great. I'd suggest reading about different types of semiconductor and semimetals.
