    Fuck it, physics is magic. You study for years to learn the innate laws of the universe and bend them to your will. You know what most people would do if magicians were real people? They’d call them nerds for spending too much time studying and most people would avoid the subject like the plague. Magicians and physicists are the same thing.

      Depends on how good the magic was. If it let you fireball a room full of goblins with a wave of your hand, read minds, lightning people with your fingertips like emperor palpatine, and conjure familiars to do your house work?

      All without any manufacturing facilities and minimal capital outlay

      I dare say physics would be more popular then

        But that’s never how magic is depicted - it always takes decades of knowledge and learning or powerful enchanted artifacts forged from rare minerals and materials, and rituals which always name a price.

        Modern magic can do all those things - if you have the right artifacts, likewise made of precious metals forged by lightning and etched with beams of sunfire and inlaid with gemstones from beyond the sea, fuelled by the ichor alchemically distilled from the remnants of ancient forests and carefully assembled by entire courts of white-robed magi who have each spent decades perfecting their deep knowledge of ritual and arcane lore.

        With these artifacts, I can incinerate an entire room with a twitch of my finger upon a staff of fire summoning, read minds with a helm of probing, lightning people with a tiny wand of stunning, and conjure familiar from across the world to do my bidding on my black mirror for the small sacrifice of tiny particles of lightning in a distant runestone.

        • Fireball? We have rocket launchers.
        • Lightning people? We have tasers.
        • Mind reading? Ok, I’ll give you that.
        • Conjure familiars? Buy a dish washer or cleaner service or whatever.

        Many of the fantasy powers can be done. It isn’t a question of capability but of economics. The economics are ignored in most stories, no matter if it’s fantasy or a real world thriller.

          Tasers and shooting lightning from your fingertips aren’t even close to the same thing

          But the point remains that, yes, society can do a thing but the power of wizards in most fantasy stories largely comes from personal, internal, strength rather than the ability to leverage a vast web of engineers, laborers and infrastructure in the outside world

          If someone dropped you in a remote area you wouldn’t just whip up a quick dishwasher to get a job done. The parallel between technology and magic as seen in most fantasy stories is weak at best

            I’m no physicist but researching this topic leads me to believe the person who posted the top comment is either a physicist worried about things that don’t impact others, or someone who has discovered the elixir of life and will live a thousand generations.

            According to perplexity, there are only 2 noteworthy consequences this could have, both of them relatively meaningless for most people’s existence today.

            First is what the end of the universe looks like (not a problem we need to worry about for all practical purposes) - If protons decay, all baryonic matter would eventually be converted into gamma ray photons and leptons. If they don’t decay, the matter will eventually be converted into… photons and leptons… same stuff, but it’ll take longer. Big whoop.

            Second is the implications on particle physics (again, not a real problem that substantially affects anyone’s life besides actual physicists) - since the stability of protons implies the conservation of the baryon number, which is a principle of the Standard Model, if protons don’t decay then… the standard model we already have is correct, and newer theoretical models attempting to unify all the forces will have a harder time doing so. That’s literally all it means, and impacts literally nobody except physicists AFAICT.

            So to the top commenter: either tell us your dirty secrets or get out of here with your alarmist crap.

    The difference between physics and magic is that physics works by describing the forces acting on a system. To predict an outcome, you just progressivly apply those forces over time.

    With magic, you just specify the outcome, but not how you get there.

    This is how we know that thermodynamics is magic. Conservation laws and Lagrangeans too.

      Weird, because my experience with science and mathematics is that everything I learned only leads to more questions. I personally preferred taking a small chunk of that knowledge and using it to do real-world stuff which was always surprisingly complicated but satisfying. An engineer that “guesses” is not a very good one IMO lol

        My whole life I thought I’d study mechatronics. I was one of those kids winning robotics comps and getting sponsored to go to global ones and get my arse beat by actually smart people.

        Anyway, I switched to physics because “I want to know why”.

        Ahaha, hahahahaha, aaahshahshshshs oh naive little me. Ha ha ha ha. Now I am an overeducated house wife with a head full of questions. I could have done something useful instead of rocking back and forth in a padded room screaming “but what is time? why does it break all the patterns?”

          Site, but that’s like saying “writing is an application of language”. The profession of writing is immensely different from the profession of inventing or studying a language. And the profession of electrical engineering is substantially different from the profession of studying electrical phenomena. There’s certainly overlap but it’s different fields.

        So you’re saying Electronics is Electromagnetics is Physics?

        In that case Biology is Chemistry is Physics and therefor Medical Doctors have degrees in Physics. If you feel like fighting me I will await you out back.

          First of all, yes - Electromagnetics is a branch of physics. James Maxwell was a physicist.

          Second - Electromagnetics is not electronics. Electronics is a field that applies electricity and magnetism to make useful things.

            Yeah but Electromagnetics is the DEEP magic behind electronics.

            You could, if you wanted, use quantum mechanics and electromagnetic field theory to do circuit design. But unless you’re building quantum computers or doing simple circuit analysis and wanted a real challenge applying Kirchhoff’s Laws, there’s no need.

            So you can use the simplified electronics model where the current (and therefore primary charge carriers) is positive.

            Electronics is a field that applies electricity and magnetism to make useful things.

            No, That’s electrical engineering.

            Electronics is specifically the study and application of devices whose properties are determined by the charge carriers themselves (the electrons), ie. band gap semiconductors.

            Whether it’s science (physics) or engineering (EE) depends on why you are doing whatever you are doing. Understand stuff? Science. Make stuff that does stuff? Engineering.

            Of course, there’s a lot of bleed and cross pollination on the bleeding edge. This is known as the science/technology feedback loop.

                  Right now I’m standing in front of the building, so I’m definitely not Stephen Hawkings. Also I’m not dead.

                  Also also, Hawkings was talented, but not a solid state physicist.

                  If you want to troll here, you need to up your physics game. At least pick a relevant dude from the scores of Nobel prize winners my discipline has brought forth in the last fifty years or so.
