What the HECK is Energy?

Just about every scientific discipline talks about energy. There are many different types: potential, kinetic, thermal, chemical, and even nuclear. It's behavior has consequences that affect the very nature of matter and space-time itself, so what is it exactly?

I have a rusty 50 year old degree in chemistry which I used to get into medical school, but I've finally retired and am trying to dust off and modernize my mental library of basic science. I used to think of this guy's videos as a sort of circus side show - freakish enough to attract attention but a bit light on substance. I clicked on this video because my brain was still aching from watching multiple SpaceTime vids, and I needed a cool-down of some sort. Instead I got an epiphany - NIck's a genius wrapped in several kilos of faux nutcase. This is easily the clearest explanation of the relation between force, work and energy I've ever seen. The little interludes of "insanity" which I used to see as irritating dork-outs (e.g. singing along to work themed songs) actually seem to serve a purpose - they're little cognitive time-outs to allow digestion of the preceding dose of facts. So, Nick, I badly misunderestimated you; this is good stuff. I'm going to dive into your backlog of videos, which I suspect contains a number of deceptively coherent gems of insight like this.

[@altrag]

Physics has a lot of "explanations" for energy, though this was certainly one of the better ones I've seen. But it only really describes energy.. it doesn't really tell us what it is. That's not super surprising though given that physics has exactly the same problem when trying to explain basically every fundamental property of the universe.. try explaining spin, or even a really common one like electric charge that you think we'd have nailed down given the success of QED. But it (currently) can't be explained -- its just a number we assign to particles to describe how they interact with things, because it lets us do math and make predictions and that's very useful to us. These aren't questions that will be answered soon. Probably not in the lifetime of anyone living today -- probing matter to that level is likely centuries ahead of us, if its even possible, barring a fluke discovery. So for now, we're stuck with just really good descriptions like Nick just gave us and try not to think too much about what it all means at a deeper level. Unless you're a particle physicist and that's your job, of course!

[@2380knight]

altrag I think it’s the measure of work, an invisible abstract force

[@argiepoul7457]

@@altrag Its impossible to find out what substance particles and even energy (if it is a substance) is because simply we can't see it, even if we see it someday we may not be able to explain what we saw and if you belive in God pray to give you some light to your difficult for science question...

[@altrag]

+Argie88 "Seeing" is a relatively loose term when it comes to physics. We can't see protons, electrons, quarks, etc. Even things as large as viruses and bacteria can't be seen with the naked eye. You could argue that a simple lens still falls in the realm of "seeing" since its just focusing the same wavelengths of light our eyes pick up normally, you still lose that by the time you hit electron microscopes and other such things. We're only seeing machine-generated visualizations of the things those devices are observing. On the other end of the scale, most astrophysics is "observed" in radio wavelengths, xray, infrared, etc -- wavelengths that again we can't "see" without help from technology. And even on the human scale, things like CAT, MRI, Xray machines, etc let us "see" things that would otherwise be impossible. In that case, not because we couldn't necessarily look directly but because doing so has some pretty negative consequences (ie: having to cut the person up!) Anyway, point is that just because we don't know how to "see" it with our current technology and understanding of physics, doesn't mean we will never be able to. String theory for example, if it pans out, may give us a lot more insight into these things. But even if its true, our currently-largest detector (the LHC) is still many orders of magnitude too weak to even think about "seeing" strings or testing string theory predictions. Sadly I don't expect us to reach the necessary energy levels within my lifetime, but you never know -- maybe some clever person will come up with a completely new style of detector that scales better than just trying to smash things together harder and harder.

[@DipayanPyne-wo8cx]

Hi Nick ! I just wanna share something personal with you. Back in 2012, during my high school years, I had a Physics teacher who taught us Newtonian Mechanics and Electricity & Magnetism. He changed my life completely, by not just making me fall in love with him as a teacher but more importantly with the beautiful subject 'Physics'. The way he explained everything, giving us proper definitions and examples to illustrate various concepts/laws, along with mathematical proofs for the most general cases, employing vectors and calculus (both differential and integral) to do so, completely mesmerized me. All the topics were covered by him in a very systematic, step-by-step fashion, from the fundamentals to the most difficult of concepts, leaving no room for confusion and making problem solving fun and easy. He remains the best Physics teacher I have seen in my life, better than Walter Lewin or Neil deGrasse Tyson or just about anyone I have come across in the last 7 years. I have often felt very sad about the shortage of such extraordinary teachers in the world, which is perhaps the biggest reason why students never realize the beauty of Physics. Just a week or two ago, I discovered this channel 'The Science Asylum'. Having watched this video on Energy (and a few more on your channel), I am convinced that your way of teaching very much resembles that of my Physics teacher back in the day. You are truly a legend, just like him. The way you cover the fundamentals, especially the definitions, with proper animations and examples, is exactly what is needed to make students fall in love with Physics. In this world where students are drifting away from science, you are a ray of hope ! I admire and respect you from the bottom of my heart. I will recommend your videos to as many people as I can in my life. Keep up your brilliant work of educating the public ! Love from India !!!

"If you can change that energy from one type to another, or move it from one object to another, you're doing work." @5:19 This is the definition that I think exists at the crux of what work is, but the more abstract definition presented at the beginning of this video covers even this.

[@Bodyknock]

Related to the point about energy either being kinetic or potential energy, I think the slide at 5:15 that shows various formulas for different types of energy really ties that point together. Just glancing at the formulas you can quickly see that they fall into expressions similar to “mass times expression related to position” (potential) or “mass times something related to velocity squared” (kinetic). Notice how none of those formulas use the square of the mass, for example, energy always scales linearly with the (rest) mass. It shows how everything boils down to individual particles moving or being in a position where a force will move them. Or in the case of a massless particle like a photon the ability of the particle to move something else.

[@LuisAldamiz]

That's a great observation, Doug. Thank you. Now this puts a twist to my question about "what are 'things' in fundamental physics: quantum fields and space time?", which I posited above. In all those formulas it seems to be "something with mass", but mass we know is nothing but "concentrated energy" (mostly the gluon field, also the Higgs field to a minor extent), so it would seem like I'm reaching a point of circular logic here. Is thus energy the potential to move or modify other energy?

[@Bodyknock]

Luis Aldamiz Energy is a property of things and not every thing has mass. A photon for example is massless but has energy equal to its frequency times a constant. The mass of something (by which I mean the rest mass) is, as you said, actually a placeholder for what might be considered energy that is potentially available but not going to be used in a given interaction the equations are evaluating. But hypothetically if an interaction converted all of something with rest mass entirely into photons then the resulting set of photons would collectively have the same amount of energy as the original object plus the energy of its rest mass E=mc^2. It’s just that in most situations the rest mass isn’t changing so is constant on both sides of energy conversion equations. What I’m getting at is a photon isn’t just energy, energy is a property that a photon has just like it has a frequency and a wavelength. The photon is a thing and when we talk about what that thing is capable of doing in the world we can calculate those effects using the values of its properties. Energy is the property that tells you how much effect a thing might be able to have on other things but isn’t by itself a thing.

[@LuisAldamiz]

But in QFT, a photon is not "a thing" but a wavefunction, a vibration in a field (the photon field specifically) that pervades all space. All particles are just waves, the most honest quantum physicists acknowledge that openly nowadays and waves are not "things" but vibrational energy of something else, the corresponding quantum field or more generally space (as all quantum fields exist in all space, even if they are at rest). Same for gluons, or more specifically the gluon field, which is incidentally the main culprit of mass and thus of "thingness" as we usually consider it, with the difference that photons are practically everywhere (even in darkness there's heat and radiation) while gluons are only in very specific locations at any given instant (outside atomic nuclei there are no gluons but there is still gluon field at value zero, else gluons, and nuclei and atoms, would not be able to move: where to if there were no gluon field to be charged with their vibrational energy?) So that's my conundrum: particles seem to be nothing but vibrational energy, so what is "something" then: quantum fields? Is ultimately all work reduced to moving energy through those fields (and thus through space) and acting on other such vibrational energies (particles)? It'd seem so.

[@Bodyknock]

Luis Aldamiz In short, yes, perturbations of quantum fields are things. Energy is not a thing, it’s numerical property of those disruptions in the fields, essentially a numerical accounting device.

[@LuisAldamiz]

Numbers alone do nothing: thus energy is something more than just "a numerical property" because it makes work. Energy seems to be a some-THING operating in the other some-THING which is space-time (or space and time as separated parameters when convenient). As far as I can tell those are the fabric of the Universe and we are all made of them.

[@tommyanderson2785]

So, (relativistic) mass is potential work you could do if you annihilate the thing (e.g. by collision with anti-matter)?

[@ScienceAsylum]

Yep... and rest mass is just a part of that.

[@DJ_Force]

The Science Asylum so, since mass is just a property of energy (m=e/c^2), and energy curves space, is that curvature relative to the observer, or is it universal? If universal, does that mean energy is "real", not just a property?

[@altrag]

Its relative (hence "general relativity.") But the relationships in GR are far, far more complicated than the "simple" Lorentz transformation from special relativity. I suspect it would be very difficult (maybe impossible) to formulate GR in such a way as to "flatten" spacetime in a particular frame of reference. More likely, everyone would see a curved spacetime, but not necessarily curved in exactly the same way as everyone else sees it.

[@DJ_Force]

@@altrag So, gravity is relative? Is the mass and gravity of, say, the Earth affected by relative velocity? Would someone in a train (trains seem to be the 'standard' relativity thought experiment vehicle) see the earth as having a different mass than someone at the station, and therefore weigh less?

The Dark energy is the energy of the existence of space itself, I guess? And the space is just one of energy form?

[@shpageltheduck6098]

Dark energy is just stuff that we don’t know of we don’t know what it is but we know it’s there because of its effects on the universe

[@baptistebauer99]

7:08 "What matters, is energy..." divided by the speed of light square for an object that possesses a rest mass. :D

[@lx4302]

this guy's energy is what makes this channel so great. also, "hey crazies", that's my kind of vibe.

[@Rafaga777]

May the energy be with you...As always clearly explained with lot's of energy and enthusiasm. Thanks for the upload...

[@rayhanmansoor2951]

So what’s Dark energy Things that could probably happen in dark Really it is energy that does things that cannot be understood by scientist

[@h2kodracu886]

Sex happens when lights are off, does it mean sex it's dark energy?

[@FGj-xj7rd]

Dammit! Sex is causing the universe to expand.

[@shpageltheduck6098]

Dark energy is just more stuff we don’t know about because of our physical limitations we know it’s there but we don’t know what it is

[@cleitonoliveira932]

Dark energy is stuff that happen and we cannot know why, but we know it's there because things are happening, work is being done.

[@howiedick6857]

So if energy is potential, then mass itself is also just potential and therefore just a number.

[@KaosFireMaker]

Yep. The potential to do work if annillated.

[@ldevika7580]

Nick Ur totally awesome! Please continue doing Ur great work.

[@user-bl1pw2th4l]

Nick you're very proficient at the side head bops! Im impressed. "Gotta go to work work work work"

[@yuvrajmahalle9684]

Careful, If you put energy all in one place it can form a kugelblitz!

[@kbbeats3099]

I believe I may have clicked on this video at a decent percentage of light speed. Finger kinda hurts.

[@shpageltheduck6098]

NorthernLightsOG you must have put a lot of work to do that meaning you have lots of chemical energy

[@calinculianu]

This is the single best explanation I have ever seen.

[@sergiolucas38]

Great video, i always had this question of what's the difference between energy and work, it's very subtle :)

[@ScienceAsylum]

Yep, very subtle.

[@jong-unkim6277]

So energy is just potential to do work?

[@ScienceAsylum]

Yep.

[@jong-unkim6277]

Phew. I'm often overwhelmed by these videos and am not sure if I get anything out of them. If I ever develop proper long range nukes, it will be thanks to you.

[@youtubesurfer586]

nO YoU!

[@Nemesisrooster]

@@jong-unkim6277 👍👍😀😀

[@davidsmulson2314]

So THAT'S what energy is!?!?!?!?!?

[@SUMANPOUDEL-BCE]

I wanted to ask you for this video earlier. But since you already had other videos about energy and i didnt saw much people asking for it so i also remained shut. But i m very happy,it finally came out.😁😁

[@4pharaoh]

You did a great job of describing many of the different types of potential and kinetic energies, and how they relate to Work. I gotta tell ya though, my instincts are screaming at me, telling me that there is a much simpler underlying principal or meaning; a simpler way of understanding energy such that all of these energies are just manifestations or perspectives of that quintessence. Or it could just be that spicy taco I just ate.

[@Master_Therion]

If energy is the potential to do work, then why is saving energy such hard work?

[@ScienceAsylum]

Because you have to save it to do specific work that _you want to do_ later on rather than letting it do the work it wants to do now.

[@BattleBunny1979]

question clone really saved this video. you should clone him a girlfriend sometime.

[@francislong5114]

Nice information video!

[@philociraptor6751]

Very enlightening, thanks !

[@ScienceAsylum]

You're very welcome 🤓
