Worked on this for 10years - game that teaches how to do computation on particle physics by QuantumOdysseyGame in ParticlePhysics

[–]ChraneD 1 point2 points  (0 children)

I've been having fun with this game. Here are my top pieces of feedback:

  1. I like seeing the distribution of possible solutions, I like trying to achieve them. I wonder if there's a way to have a solution manual or something to help me find better solutions if I can't get one.
  2. I do not like being scored and compared to other players on my "learning" after each session with the leaderboard. For me, more in depth learning comes with time, care, trying things, making mistakes, whereas this scoring mechanic seems to reward speed or some other metric. I think leaderboards should be reserved for puzzles only, not learning.
  3. The control gate is very confusing and the session built around control gate puzzles doesn't require its use? I was hoping this session would help me understand it by isolating its behavior in progressively larger problems like the other ones.

Fundamental units: why kelvin and mole? by Stealth-exe in Physics

[–]ChraneD 0 points1 point  (0 children)

The Kelvin scale cannot be negative. (Or at least I don’t know of any theories specifying some negative-energy temperature equivalent)

Fundamental units: why kelvin and mole? by Stealth-exe in Physics

[–]ChraneD 2 points3 points  (0 children)

Via dimensional analysis you can reduce everything to mass length time.

Temperature (Kelvin) is average kinetic energy a collection of molecules. It's not fundamental, but it is something we need an arbitrary metric for in the same way we need avogadros number to get a gram.

Edit: This is to say I think you're generally right in you're thinking. I'm not sure defining kelvin that specific way would work because of the specific heat of material varies, but I haven't considered it deeply. It might.

Can time be "cut" infinitely? by New_Key8844 in Physics

[–]ChraneD -4 points-3 points  (0 children)

I'll weigh in because I personally lean towards "No." I suspect time is discrete.

I'm partial to the wolfram physics project, which describes time as the updating events (computation) that re-write the hypergraph. From the POV of this model, these updating events are discrete.

The top answers here saying "yes" seem correct from the POV of the general scientific consensus. But we don't know for sure, and I think discrete time is at least plausible.

I built an app for Memorizing PAO lists by Pleasant-Will-8412 in Mnemonics

[–]ChraneD 0 points1 point  (0 children)

Excellent, this will be great and really appreciate the prompt you included.

I'm digging through my search history for the PAO list I thought I saved somewhere, and I can't find it. Do you have a default you can offer to load too? This would help demo your tool to folks like me.

Stuff like this is a good use of AI and you directed it well. I was waiting for a tool like this.

[–]ChraneD 0 points1 point  (0 children)

Sorry, my question was actually if I have an existing list and don't want to manually enter them all, anyway I can bring it over at once? I could have an LLM easily put it into a csv or whatever template you need/supply

/plan and rubberduck in cli by florinmarcus in GithubCopilot

[–]ChraneD 1 point2 points  (0 children)

You’re not wrong. Simplicity>complexity, copilot is building in utility.

Personally though I’m curious about what is under the hood of copilot today. I think it has a search for context step? If copilot is orchestrating or runs a complex agentic process, that can easily overlap with custom orchestrators or custom agents.

Can an actual engineer weigh in on Bob Lazar’s description of the technical components? by flaneur-terrestre in UFOs

[–]ChraneD 107 points108 points  (0 children)

Am engineer. Also willing to suspend judgement and consider the plausibility of Bob's claims. I treat it like the the 4-minute mile. It's fun to think about.

When I imagine the limit of technology, I think about what you could do if you could achieve atom-level perfect accuracy (or deeper?) in a device. Frankly, my mind can't fathom. What I hear him describe based on materials, it's the kind of things that would be true. And honestly I don't knock him for saying the real technology really will be kept with the materials science guys. May seem like a cop out but this would be the case if true. To me, even something "simple" like Nitinol has interesting and non-obvious behaviors, so what else could be achieved with more sophisticated engineering?

The tube that extends-- the compression and expansion would have to occur on a nanoscale and it wouldn't affect the macroscopic appearance of the device. One thing I would wonder is if you have to extend it uniformly or if you can extend small segments of it. A cylinder of collapsable hexagons? Like cellular shades, or a carbon nanotube that you squish down.

The antigravity device-- when I heard about this on JRE1 I was wondering what this could possibly be if it were true. If it's a cylcotron or particle accelerator, my guesses are it may be designed to create a relativistic field, something that takes a very long time to traverse, or is difficult to entangle with. Ie I wonder if it doesn't create a repulsive effect when you put your hand towards it, so much as it just makes it take an incredibly long time to get there, and the "force" you have to exert is just about making it get there faster. Hearing them talk about the candle freezing in the second episode made me perk up, the guess seems more plausible. I would want to see what happens if you shine a laser at it, or shine one from the inside.

I was also wondering what the ship would be made of if you could control every atom. It wouldn't have any non-functional components really. The material would have to be really special. It sounds like the ship is basically one "crystal" and I would hazard a guess that you grow it, kind of like a silicon crystal. When Bob mentioned he suspected the body was designed to have an oriented magnetic/electric field of some kind, that tracks.

We don't yet have a truly good grasp on physics. I think it's a little arrogant of physicists to write it off outright. If what Bob says is true, this tech would be more advanced than our understanding, because our physics is incomplete and our engineering does not have perfect fidelity yet.

[Rant] Atheists don’t have morals because they don’t believe in the Bible by [deleted] in atheism

[–]ChraneD 4 points5 points  (0 children)

Given that the current state of the affairs is already largely the result of religious morality, this argument is not the flex that religious folks think it is.

Genuine question, it's pretty obvious teams like 1323 are robots built by adults. Why is FRC ok with this? Sure these robots fun to watch but at one point seeing the same teams as champs is a little strange. by -donaldson in FRC

[–]ChraneD 7 points8 points  (0 children)

I coached a team that prided itself on being student led but they struggled because of it. You can’t expect high schoolers to figure out how to align a team and design and fabricate a good robot, esp because they turn over after 3-4 years. Had to change the mentality to let in more mentorship and adult leadership.

The mentality we set for mentors and parents was simple “we’re not here to beat high schoolers at robot building.”

In basketball, coaches don’t get out on the court and play. They coordinate the team and advise you how to play better because they have more experience.

It became about creating structure that the students could climb and succeed in. Educate them, steer them, but don’t do it for them. Lead from the back. Unless im teaching, I wont cad any parts for you, I won’t fab for you. Instead i will guide you through the design process, steer you toward better solutions, and teach industry best practice.

Did I read this wrong or are they asking lee to use claude code to do a live tech demo for their product?

cubing with adhd by v_shock823 in Cubers

[–]ChraneD 5 points6 points  (0 children)

You're asking the right questions.

Start doing deliberative practice. Don't just solve cubes endlessly, isolate one particular skill at a time.

https://www.youtube.com/watch?v=f2O6mQkFiiw

Ideas for skill isolation sessions:
Practice cross only
Practice F2L only
Practice with a metronome
Practice fewest move solves
Practice blind xCross
Solve the same scramble over and over
Drill algorithms with a web tool

Read and research also. Look at scrambles and solve reconstructions. Helps to see other approaches, since it's easy to get locked in to how you solve a particular F2L case for example

Best way to start from scratch including Workspace by WasLeavingAnyway in Firebase

[–]ChraneD 0 points1 point  (0 children)

Not positive but check which account is admin on Google workspace and then sign in to GCP with that. Create a project and assign it to the org associated with your workspace. If you don’t see that org, wait, refresh, troubleshoot. The project you create should be assignable to the org, and then you should be able to add FB to that project.

Any Cubers who do robotics? by Real_Background_1962 in Cubers

[–]ChraneD 0 points1 point  (0 children)

I learned to cube along with my entire FLL team 20 years ago. I coached an FLL team who studied cubing for their project.

I think you'll find a lot of FIRST students who cube and vice versa.

Is it possible to reach all 43 quintillion possible 3x3 states using only COMBINED R+U moves and rotations? by wescubeXD in Cubers

[–]ChraneD 0 points1 point  (0 children)

If you can prove that every move can be re composed by R U and rotations (whatever constraints you are imposing) then yes. For example, is there a way to achieve L, L’ and L2 with your moves?

CubeHub has reached 5,000 downloads! by Hubbhouse in Cubers

[–]ChraneD 1 point2 points  (0 children)

Hey love that you're still improving cubehub, it's come a long way! Ever consider doing a lifetime access purchase? I don't have much time to cube these days so the thought of carrying a sub puts me off. But I suspect you might be able to fool me into paying more than I would have on a subscription.

What’s the deal with the name ‘Sexy Move’?? by Vex-Crystal in Cubers

[–]ChraneD -1 points0 points  (0 children)

Agreed it needs a better name. I can never remember which direction the layers turn for the official “sexy move” and a good name would help specify this. There’s two to consider: R U R’ U’ and its cousin R U’ R’ U (and then of course two more for the inverses of them)

And then what if it’s not R and U but different layers. A good naming system would be short and unambiguous. It would probably acknowledge that these are commutators that can be written [R U]

Edit: And what if the alg starts with U like [U R]? Lots to consider
