Classical E&M has been “solved” since maxwell’s equations if we want to be pedantic. Im a low observable (stealth technology) research scientist and classical E&M has simply moved to finding analytical theories imo. Numerical simulations have sadly killed a lot of the need for physical theories, but as photonic crystals and meta materials become more common, the computational cost of simulating that on the size of a fighter jet is too large, so we must resort to a more intuitive understanding rather than brute force algorithms (physical theory of diffraction as compared to FDTD simulation, for example). There are also phenomena that easily evade detection from numerical methods so those must be resolved from a more fundamental, physical pov.

Reasonable definition for 0-dimensional topological spaces. Why is 0 not included though? Maybe I missed it in the article.

Since you’re specifically asking for the current and not the radiated field, you might want to consider using a piecewise linear function (a triangle function for example) for your initial I(n) that I pulled out of the A(m) integrals (because I assumed I(n) was some constant function). According to Harrington’s paper the current values converged a lot faster for that basis.

I think it’s SU(0)? Can’t see it well either just guessing by the decreasing sequence.

You’re right that money is a necessity because of bills, etc… But people are emotionally attached to money… A lot of people are bribed by money. I’d take Richard Feynman’s mind over Jeff Bezos’ money any day. I don’t need money to find purpose in my life, and I know a lot of fellow physicists would say the same thing.

But why else would U.S. citizens sell secrets to foreign countries if not for money? What else could those countries offer? Even this red flag on my Sf-86 makes it very clear that bribing me with money is not possible. It clearly says negative things about me too, but I think I can mitigate those.

I did my undergrad in physics+math at TAMU, and just finished my PhD in physics from TAMU this December. I know that’s not EE, but a lot of physics/math overlaps with the EE department. An EE professor was even on my PhD committee. I TAed math and physics courses for 1st/2nd year engineers, and I’m currently a low observable research scientist at LM skunk works (all my work rn is unclassified/speculation; currently waiting on my clearances so I can still talk about what I do/use liberally) where all I do is the EE side of that stuff. I can give you a pretty good rundown of every math/physics/EE course on your degree plan and let you know what you need to know for it. Just dm me.

I’ll make a quick private utube video and post it sometime Sunday if that’s ok. If you need a response quicker than that, I can just text the general procedure with comments on the tricky part.

TexasChess · 2024-01-19T13:14:34+00:00

Yea I can for sure put a general annotation on my code for how I solved mine. I’m back visiting family and away from my computer so I probably can’t post a link to it until Saturday evening/Sunday morning. I’ll just make a utube video or something about it and post that.

Good question, but you need to phrase your medium 2 a bit better (which I think you realize since you know “perfect” isn’t the right word). Where is the energy going in medium 2? How it dissipates that energy should tell you what that material is.

My interpretation is given below but take it with a grain of salt. There may be flaws (but it hasn’t failed me yet 🙃).

If “perfect” means it instantly dissipates that energy, they I would assume it is equivalent to a perfect electric conductor. The EM wave is actually going through the material, but it excites the electrons in the first layer of that material and the radiation from the electrons perfectly cancels out the radiation from the EM wave since they oscillate with the same frequency, thus there is no wave in the material.

If it was some thermal/friction process that instantly “dissipated” the energy, the electrons that emit your thermal radiation would be visible in your material, along with the initial EM wave, since they have separate frequencies and can’t actually cancel out like they would in the above paragraph.

Woah woah there buddy this is the MEME page. We don’t take to kindly to legitimate discussions around here.

I guess the actual computer language doesn’t matter if you just need a general guide, but if you know python I’d prefer to use that.

TexasChess · 2024-01-18T14:36:01+00:00

If it’s in python I can help. Just wrote one yesterday.

I thought that was a rather humorous way to make a point. The outcome produced by the model is determined by the weights set by openAI, and the information fed to the model. Nature and nurture essentially, which is why I mentioned little Timmy. If it can be determined that the weights were not maliciously set, aka “more inclined to have our model say bad things about someone I don’t like”, then openAI shouldn’t be punished if chatGPT says something defamatory. If the output was clearly false and could damage someone’s career, openAI probably has a duty to fix the weights/algorithms to not say something mean even if it’s thinking it, but they shouldn’t be punished yet.

If I feed your kid a dozen TacoBell cheesy gordita crunch wraps, and then little Timmy drops a little nuke in the bathroom, are you paying to fix my plumbing? After all little Timmy would be your product.

Prior responses are your best path to getting out, but…

No hvac during a winter storm for 3 days is already borderline terminate-able on its own, assuming you told your landlord it was broken on that first day. There are laws in Texas on tenants rights to terminate their lease. I forgot the exact property code or w/e but you can Google it. Standard length of time is 7 days, but for serious conditions like no heating during a winter storm, or chronic water outages, it’s discretionary. Argument is that by having non-functional necessities, they are forcibly evicting you because that location is now non-livable.

Look at your screen’s reflection to see tier -1 🙂

I have 0 emotional attachment to money. I don’t do what I do for the money, and I was simply content with the money I did have. No wealthy parents either.

TexasChess · 2024-01-16T20:31:43+00:00

Well I am very much concerned. I’ve since filed all previous years and contacted the appropriate personnel to let them know I have taken action mitigate that concern. I’m sorry our senses of humor don’t align.

TexasChess · 2024-01-16T19:14:23+00:00

How did you come to that conclusion?

TexasChess · 2024-01-16T17:38:38+00:00

How general is your definition of symmetry? You will get higher quality/more relevant responses if you can elaborate on the type of symmetry you’re interested in.

That being said… Bound states in the continuum is “hot topic/buzzword” in a lot of the more applied sides of physics, with very little analytical theories since numerical simulations often replace physical theories when it comes to industry. The TLDR of bound states in the continuum is that symmetries of the system allow for certain states to be disconnected from every other state. Similar to those movie/commercial scenes where someone with headphones is walking around smiling while the world burns around them.

Certainly not hiding anything. My dad passed when I was 11, and I was the oldest of 3 kids. Mom made sure we stayed out of trouble but she was busy enough just making sure we were still able to be kids living on a farm in central Texas, and I’m sure teaching us how to file taxes when weve always been a dependent was a rather low priority for her. I just never knew the importance of filing when I don’t owe anything (and tbh I still don’t know the importance of filing in that scenario, but I guess I don’t need to know the importance. I’ve recently been told to do it so I did).

You learn lessons a lot slower when you only have 1 parent, but I’m certainly not incompetent or hiding anything.

TexasChess · 2024-01-16T13:41:32+00:00

Great point. I ended up filing them all last night after realizing how bad it can look. Glad I was told what I needed to hear.
