    I switched from ubuntu to debian when 12 was released and it’s been fine. Only thing i was worried about was running WoW via lutris but had no issues.

    So when my SO windows pc died we bought some newish parts and i installed debian on it as well. Also installed chrome since that’s her browser of choice. She’s still getting used to gnome, but all she needs is browser, WoW, and libreoffice, which is close enough that it hasnt been an issue. She doesn’t even know how to update the system.


  • I teach my physics undergraduates the basics of latex for writing. They usually figure it out. It’s basically like writing some code. The biggest pain are graphs. And like a lot of code these days, chatgpt can help a lot.

    If you just need to write basic text formatted using apa, you could find or create a template and give it to your students. Then they won’t even need to think about the formatting cause the template will deal with it all correctly.

    Oh, i should add, in that screenshot, most of that code creates the fornatting. Once that is set, your actual content with words and paragraphs looks mostly like text.

    Start with a minimal preamble and start testing it out.

    I’m a college professor. I’m very aware of textbook prices. Most students don’t read the textbook anyway, even if its something you want them to read everyday.

    For intro classes, I use openstax, which are available free online. For upper-level classes, I try to pick non major publishers, ie not pearson or cengage, with much more reasonably priced books.

    My version of this meme would be the prof begging the students to actually read the book he/she picked out that is free or cheap so that they are prepared for class and the students rolling their eyes and instead just going to chatgpt or chegg…






  • I assume you mean grip strength instead of arm strength. I go overhand grip for my first two sets at 135 and 225, but then use switch grip on my higher sets. It allows me to not use wrist wraps. Try out switch grip and see how much you can do. Deadlifts will increase your grip strength.

    My deadlift day goes: 10 reps at 135, 10 reps at 225, 1 or 2 less than max effort at 315 (usually around 5), 1 rep at 405, and 1 rep at 405 + some change to try to go for max or more. I sometimes fail the last rep. The first two sets I try to really concentrate on my form.




  • I don’t think it’s too much. I don’t really consider deadlifts that much of a leg and instead a back exercise. I also go 1 rep max on deadlifts, where my 2nd to last set is nearly max and last rep is max.

    I’d recommend doing romanian deadlifts instead of leg curls or leg press. I added them in the past year and really feel them. I do them elevated so i can really get low with barbell.



  • Linux mint or fedora are great options. I’d probably recommend mint as usually geared more to those switching from windows and the forums and communities might be more helpful for beginners.

    I’d avoid ubuntu these days. While not horrendous, i’ve run into enough annoyances with their snap package manager that there’s just no reason to learn this additional thing for a beginner.



  • From your first 3 points:

    1. Spacetime is not a fixed grid. Einstein’s theory of curved spacetime has been supported by numerous experiments: mercury precession, observations of stars near the sun during a solar eclipse, gravitational waves, etc.
    2. Planck time is defined from the Planck length and the speed of light, so yes, this is by definition true.
    3. Define evolve and self-propagate. Protons or electrons certainly do not produce copies of themselves, at least to my knowledge, as this would violate conservation of energy, momentum, spin, lepton number, etc. Show me a proposed process where an electron creates two electrons that does not violate conservation laws.

    Big bang theory makes a hell of a lot of sense, and currently explains CMBR extremely well. The cause of the big bang is obviously still unknown (if that is even a reasonable question.) Not liking, or understanding, the theory is not reason to dismiss it. “Spewing information from digits of pi?” This is pure stoner talk. Digit of pi are arbitrary, and are different in different number bases: decimal, binary, hexadecimal, etc. Numbers are also not things in physical reality, only conceptual concepts.

    From your properties of a graviton:

    1. Size is unrelated to being detectable. In addition, in particle physics, size is a bit fuzzy, since all particles are waves, and “size” might be defined by the wavelength of the particle.
    2. Gravitons are proposed as the force carrier for the gravitational force. But possibly don’t exist since Einstein’s theory demonstrates that mass curves spacetime instead, and gravity is not an actual force, and thus no force carrier required. This contradiction is one problem with merging quantum theory and general relativity.
    3. Sure, if a graviton was emitted, dynamics could be worked out to determine where the emitting mass is, similar to emitted photons indicating where the object that emitted the photon is.
    4. Vector directions are arbitrary. A vector is not a thing, but a mathematical construct used to define magnitudes and directions. Negative vector is only an instruction to reverse the direction of that vector.

    Particles exhibiting intelligence? Define what you mean by intelligence. How does a photon “try to survive”? Current understanding of particles is that they obey very predictable rules governed by quantum theory, which doesn’t indicate any intelligence or decision making from the particle.

    Finally, for your use of gravitons:

    1. This could be measured in a lab. One could measure a particle decay through an unknown mechanism. As far as I’m aware, this has not been observed.
    2. Mass is gravitationally attracted to mass. Sure. Gravitons are the proposed force carrier for gravitational force. If they existed, this is how they might work.

    You have an interest in physics, which I applaud, but you should read some introductory physics textbooks, or enroll in undergraduate introductory physics classes, and master the fundamentals (Newtonian mechanics, classical electrodynamics, quantum, stat/mech).
