  • I used the higher level 3-dimensional definition of work, and you told my I was wrong and provided my the high school level 1-dimensional definition of work. Then you hang it over my head and try to correct me as if my definition is incorrect.

    The fact is your knowledge of physics is so low that you didn’t even know this nuance; and you are not arguing in good faith because this is something you easily could have looked up and realized if all you cared about wasn’t “being right”.

    Not AI. I’m in academia, so I write academically.

    I specify “physics work” to mean physic’s definition of work (dot product between Force and Displacement).

    And to not connect the importance between the electric and magnetic field as it pertains to the the electrostatic force and magnetic force reveals your basic understanding of the physics. Hence, why your prior comment was so problematic…

    Oh boy, this is very incorrect, because it sounds like you are attempting to explain magnetism with electrostatic forces. Here is a basic model which separates the difference between the two:

    1. Electrostatic forces are caused by the electric field. Something produces an electric field simply by having an unbalanced charge. Positive attracts negative, negative repels negative, positive repels positive.

    2. Magnetic forces are caused by the magnetic field. Something produces a magnetic field by having an unbalanced charge AND is moving.

    This is why when trying to explain how solid magnets work, we focus on the electrons because electrons are charged particles that are always moving. So they produce both an electric field (being charged) and a magnetic field (being a moving charged system).

    Rhaedas is sorta correct. Any solid system has the capability of being a magnet, but this takes an incredible amount of physics work where iron is special. Iron’s electrons are able to easily maintain a synchronous orbit with each other which results in magnetic forces being observable at a macroscopic scale (seeing iron magnets pull on each other). In most other materials, the electrons orbits are chaotic, so even though magnetic fields are still being produced by their electrons, the lack of order results in no magnetic force being observable on the macroscopic scale; but if you place this non-iron material within a very strong magnetic field, you may be able to align their electrons orbits so that it becomes magnetic on the macroscopic scale (like iron).



  • This is a major L take. Your argument is to compare bad behavior performed by a 5 year old child and a grown adult, and say “they are basically equivalent”. The Internet is trying to point out to you how ridiculous it is to hold a 5 year old and professional adult to the same standards.

    The teacher is hands down “the asshole” in this scenario, and I am saying this as a professional public school teacher. Yes, the five year old was wrong to steal, but the kid is five and is in the process of learning what society considers right and wrong. The teacher escalated the scenario due to her bigotry and then expected the father to be susceptive to her concerns about the child stealing stuff. She should have professionally address the behavior to the child’s parents and admin (especially if it was repeated behavior) so that the team can help the child understand why what they are doing is incorrect.

    Head over to Norfolk, Virginia and tell them that they are to ignore the years of racism that they experienced and fight a class war. This is the divide racism creates. If all sides can’t come to terms, then asking them to join and fight a class war will be extremely difficult; and a big part of this is white america finally coming to terms with their privilege and actively destroying the caste system.

    Hence, why the bosses have been actively demonizing DEI and CRT to maintain white america’s denial of their privilege so that it continues to stoke the divide between the castes.

    But you make a point, perspective is everything. Folks in middle america do not see their privilege as much because a lot of them live in towns full of other white people. This means they are largely of the same caste. Nevertheless, they are essentially being convinced that their grievances are due to dangerous people of color elsewhere in America.

    That is frankly false, and also my biggest gripe about the modern communist movement. Racism is basically America’s caste system. If the caste system isn’t destroyed either before or during the class warfare, then it will either reform after a revolution or prevent people from banding together to form a revolution in the first place.

    Telling people that racism is a distraction to be ignored is a major mistake. If the modern communist movement wants their class revolution, then this would be far easier (or actually possible) in a America without racism. Hence, why bosses have been perpetuating Racism in America for hundreds of years.
