Thank you all for you insights, in none of the pop-science sources that talk about string theory etc. did anyone ever mention that compactifying higher dimensions is the equivalent of GR for other forces. That makes the introductiont of those higher dimensions suddenly make perfect sense, rather...

As far as I know, the grand prize of a Theory Of Everything is mathematically uniting of all forces in the conditions close to the big bang but one of the main problems from the GR end of things is that gravity is not actually a real force to be combined with anything. All the most popular...

As a note to the previous post, I've noticed that Sum/Dev and Mode/Dev should be swapped, as I mixed them up in the code. Also, on second though, I'd rather lenghten and flatten the very last one, "Mode More turbines" rather than just flattening Sum/Dev, as it starts at higher power and already...

I'm not sure if I have the right words to put it in proper terms out of context, but perhaps I can illustrate it. Below are two charts my script generates (the timesteps for the x-axis are 1s) This graph shows the modeled level of the sea vs. level of water in a lagoon basin. The water drops...

I'm sorry, I got back home and was trying to export the data to either an xlsx or txt, but the data consists of two 21601x40x50 arrays. Each file ends up being about 500 megabytes. And it's either that or 100 ~10MB files. Either way it's about a gigabyte of data.

Since the problem is about power generation (hydroelectricity), time is also a factor, i.e. if delivering a lot of power over short time gives a lot of total energy with low variability, but is not fit for purpose. That is actually a problem I run into, mostly because of working with an ideal...

Ok, can't do it right now, but I will in a few hours. As to the function, I wrote the script in MATLAB R2018a, is that the issue? Because rmmissing just deletes NaN values from the matrix.

Sorry, I now realize it wasn't clear. TideHeight1s is source data for the .m script, the code for which I've attached in the .txt file. The data I want to optimise is generated by the script itself as a 3D array. I'll edit it into the OP. I can export the end data if you think it'll make more...

Hello, I'm currently working on an assignment which requires me to choose an optimal curve of power generation based on data points generated by a script I wrote (attached for reference, TideHeight1s is the source data for the script, the txt file contains the code for the .m script). The...

I had to re-check what type of star Tabby's star is, because I was absolutely 100% convinced it was a red dwarf.

I think you're abusing terms such as "persistent", "rational" and "random". Organic chemistry had been proven multible times to spontaniously arise from inorganic processes, and both have favoured routes of dissipating available energy. All of this is already rational, not particularly random...

I'm trying to run with this idea and figure out what purpose would making a "blue dwarf" have. Could it produce heavy elements without going supernova like a heavy star? Would it be a more efficient power source that your garder variety Dyson sphere?

All right, that's brilliant to hear. I'm not trying to aim for a specific velocity, that's why I'm not concerned about drag or exact values, but I was worried whether the pressure/energy could have been off by an order of magnitude.

Hey, thank you for those. Yes, I'm considering gauge pressure and yes, I agree, surface area compared to it's mass dosn't do a plastic BB any favours. Certainly not compared to the drag/mass of a lead pellet. However my main question is still rather about the adiabatic work and whether 10 bar...

As in the title, I'm trying to establish the approximate velocity (sans friction and other losses) of a pellet propelled by compressed gas from a tank. Below is what I have came up with myself, I would appreciate if someone could review this as say whether the end values are reasonable. I have...
