I guess one of the biggest facts and ways to explain the energy theorem, "energy can neither be destroyed nor created, only transformed from one or another" is the fact that energy has a tendency to expand, and like said above, get transformed into different energy; but the total energy will always remain constant. I'm not a pH.d professional or a professor to explain this well but I'll try, if you take a hot object with energy of 10. And that hot energy spreads out in the environment slowly, the environment gets hotter. But would the energy of the object decrease since it's technically given away a part of it energy? No! It wouldn't lose energy. it's total energy would always remain 10. That's kind of the beauty of entropy. And i think explains the theorem very well. How energy cannot be created nor destroyed. And the energy of the universe remains constant despite it's expansion. Sorry for the ramble, I know you didn't ask for this. I just felt like talking about it.

Flawless video. Energy is a fundamental concept in physics that refers to the ability of a system to do work or cause a change. It is a scalar quantity that is measured in joules (J) or other units such as calories or electronvolts. There are many different forms of energy, including: Kinetic energy - energy that an object possesses due to its motion. Potential energy - energy that an object possesses due to its position or configuration. Thermal energy - energy associated with the temperature of a system or object. Chemical energy - energy stored in the bonds between atoms and molecules. Electrical energy - energy associated with the movement of electric charges. Radiant energy - energy that travels through space as electromagnetic waves, such as light and radio waves. Energy is the ability to cause change or do work. It comes in different forms like motion, position, temperature, bonds, electricity, and light. Energy can change from one form to another but the total amount of energy in a closed system remains the same. This means that energy cannot be created or destroyed, only transformed.
Neil, as usual, is correct on the broader points. Which leaves me scraping the bottom for nits. Of which, as usual, there are several: • The concept of _phlogiston_ was invented to explain fires-that is, the why's and how's of burning aka combustion. Obsolete now; it's been replaced by chemistry. • The concept of _caloric_ was invented to explain heat flow. Obsolete now; it's been replaced by thermodynamics. • Classical thermodynamics explains concepts like thermal energy, heat flow, temperature, entropy etc. without resorting to atoms and molecules. • Atoms were postulated several millennia ago by Greek philosophers such as Democritus. However, they became accepted by modern science only from the 19th century onwards, due to work by Dalton, Einstein _et al._ • Thermodynamics can be reformulated in terms of atoms and molecules, giving us _statistical thermodynamics._ Classical thermodynamics emerges from it at macroscopic scales (akin to how classical mechanics and classical electromagnetism emerge from quantum mechanics). • And finally, an internal combustion engine gets hot because *there's literally combustion happening inside it!* 😜
I was hoping to hear something about entropy too, because there's such a close connection between energy, heat and entropy. It's also worth explaining the 'heat death of the universe' and of course how it's connected to energy and entropy. But maybe next time.
@@akakakaka287 Partially yes, but I find your explanation a bit incomplete, we must talk about a system if we talk about entropy. Calling it spontaneous heat (or waste heat) is too simple. The reason why I would gladly hear more about these, is because most people don't understand the connection between energy, heat and entropy. It would be so nice to hear a great explanation, it's effects on the whole universe (heat death as mentioned), maybe even something about black holes and Hawking radiation too.
@@akakakaka287 I agree with @Mikáci's last elaboration. Entropy is much (MUCH!) more complicated. For one, it is not "disorder" as is often mischaracterized ("disorder" is an over-simplification & partly inaccurate). Hoping there's a 2nd+3rd video: energy, entropy, MassEnergy (since mass/energy are the same thing), how energy transfers ("moves"), equilibrium ("heat death" & Hawking radiation)... many complex aspects.
Energy (force) is spin, which creates a vibration, the force is created by the presence of matter. Force shapes matter and matter generates force. They are two equal opposites that are connected, they exist because of each other and the universe is shaped by their shape & interactions. Matter has physical limits, force does not. Force is able to pass through itself & matter, matter cannot pass through matter. Dark energy is our lack of understanding of this, dark energy describes something that we can’t see with our eyes, this is force.
You know what energy is, you pay for it every month when you pay your electric bill. Energy = Power x Time. If you have 120 volt outlet, and you plug in a bulb that draws .5 amps of current, that means the bulb draws 60 Watts of power. If you keep the light on for 1 hour that is 60 Watt-Hours of ENERGY. Keep it on for 10 hours and that is 600 Watt-hours of ENERGY. If you had a bulb that draws 50 amps of current that means the bulb draws 6,000 Watts of power. If you keep the light on for 1 hour that is 6,000 Watt-hours of ENERGY. If you leave the light on for 10 hours that is 60 KiloWatt-Hours of ENERGY (60,000 Watt-Hours of ENERGY.) That's what energy is, an accounting system of Watts and time, which is POWER x TIME. ;)
Neil I am over here trying to focus on work!! Then I go and get a notification from you. Now I have to stop what I’m doing to listen wait to what you have to say!!😅
Love to see this editing going forward, 1080p with some videos referencing what is being talked about to make it easier to imagine what it would look like, amazing !
I can (and often do) watch Neil content all day. I just wish that I could have had him as a teacher back when I was in high school, as he makes learning a pleasurable experience 👏👏
You realize that at his core, Snake in DeGrasse Tyson believe that the world would be better off if half of you were 'gone', right? You can get back to fellating the enemy of your children now, if you like.
he wouldnt be able to maintain this kind of energy for an entire semester. nobody could. he only gives you the highlights and headlines . the most interesting bits of science. its an unrealistic bar to be set for other educators. behind every cool science factoid or concept theres tons of boring, mundane, repetitive, mind numbing sessions of memorization and pedestrian grunt work involved.
@@ShortFuseFighting Yeah, I came to this realisation the hard way. People (including me) think that they understand the concepts being talked about at a higher percentage than they actually do (the Dunning Kruger Effect) it makes it seem fun because its been oversimplified. However when you actually read about the topic and have to put in the hard work, memorise and think you understand the really almost monumental jobs that have to be done by teachers to teach children 80%+ of whom have no interest or the true capacity to understand these things on a more fundamental level. I've heard hundreds of hours worth of information about black holes but in reality I cant do any of the math or physics but understand the very simplified basic concept and factoids because they seem cool to me.
@@ShortFuseFighting Lol what? There are plenty of professors out there who stay excited for the class topic the whole semester. Also idk why that Ambrosia guy is talking about dunning-kruger and all that stuff when OP didn't even say anything about their perceived level of intelligence on the subjects lmao. All they said was "I love Neil because he makes learning fun." I think you guys need to pull the stick out of your black holes if you know what I'm saying
I’m a retired fireman. We used to use steam conversion in confined attic fires- taking advantage of the 1700 times expansion from water to steam!!! And good on us for finding a way to use the byproduct of boiling water!!!
This man shows you how fascinating physics can be... If only we would get the same kind of vibe and lessons from the teachers in school, the world would probably be a better place...
As a 13-year educator I can say a couple things about this. First, this quality of teaching sometimes DOES happen in schools. And teachers who teach like this in any subject are often denigrated by their administrators and colleagues for being “too cool” or “too informal.” Why? Because this style of teaching isn’t in the textbook. It comes from deeply understanding the field of study he’s talking about. Deep understanding isn’t as valuable to our educational systems as is obedience and conformity. It’s super frustrating.
I had two burned out Science teachers in high school, luckily the last one, Physics was not and that's when I decided to go for double major of Electrical Engineering and Computer Science in college.
I shared this video with my brother a former cannon cocker with the US Army, just to hear him vent when Neil said "back when cannons were a popular tool in warfare". I had to pause the video for 20 minutes while he explained the evolution of the cannon from the Napoleon era cannons all the way to the modern M777 howitzers that he used to crew. Listening to him get triggered was worth the delay.
- What is energy, really? ...i'm still learning the answer to this question... it seems like a mysterious sort of "thing"... like phlogiston or Caloric... but i know there's an even deeper understanding of energy that is not crystal clear to science yet... 2:20 - the Calorie & the Joule can measure energy... but i don't think they "define" it 10:19 - Also, i believe Chuck has much potential 11:31
Misleading title. This is more about "what are the different kinds of energy we encounter and how are they stored and converted?" The question of what energy is is not covered.
I started looking for videos to explain what energy is a few days ago, so this is a happy coincidence. But I still haven't found the answer, because mostly people are explaining the various forms it can take. But I am beginning to suspect that we still don't have a clue what it _is._
Life force & consciousness are also energy which is converted from the things we consume. All energy has spin. Even the circle of life. Even life & death is simply energy changing form. Your force is eternal. All energy, no matter what form it takes, has the same pattern of behaviour. A cyclic, duality of force that has a pair of vortices rotating in equal and opposite directions, exactly why for everything there is an equal opposite. You can see the spin in trees growing out of the ground, tornadoes, waves at the beach etc. etc. you can observe the force moving through all matter around you, I have countless examples of what it looks like, and I can share enough of my perspective to answer some of your questions.
@@Justin-gv3lp it is spin. A vibration that is caused by spin. The vibration is caused by the presence of matter, and the vibration shapes matter, which in turn shapes the vibration. They are two equal opposites, one is matter, the other is not, but they are connected.
@@Justin-gv3lp keep wondering, there's a whole universe to wonder about. Saying energy is the ability to do work is like saying water is what's required to turn a water wheel, it doesn't say what water is. Particles are the form of energy that fascinates me most, because it's energy that's kind of resonating eternally, like it's moving really fast but mostly in one place.
“Energy” is actually just an artificial concept to simplify physical formulas. It’s a math trick. Strictly speaking, there is no such thing as energy in nature. Or, as Neil put it in the video, it’s nothing you can point a finger at.
My understanding of energy is basically motion. Kinetic energy is motion in action. Potential energy is motion that can become action in motion. This seems to hold true for everything, from vibrating atoms to zooming protons to propagating EM waves. It's all physical motion.
There are different kinds of energy, though I'm not enough of a physicist to explain it well. Electromagnetic, has properties different from other kinds... Like electromagnetic can cancel out (block?) electromagnetic energy of the same frequency... Unfortunately, I cannot articulate a good rebuttal 😅 Too much for this bio guy lol
@Tragoudistros.MPH what you mean is a wave and a 180-degree shifted wave of the same magnitude and frequency. Their peaks and valleys cancel. But it's still motion. And unless they're traveling together, the original propagation will continue past the point of incidence.
So the energy in our universe is finite. Every thing we in our universe from matter to photons was created in the big bang. So if energy can't be destroyed then if our universe keeps e
Chuck 9:10 that is why " the ROOF the ROOF " was on fire, the party got started. All that ENERGY of JOY and Celebration!!!! When the Dj drop that beat and cut it up.
i have a terrible science teacher this year...now while i still have an A because i just figure things out, i swear this man here is going to carry me so much this year
I have always asked me what energy even is, because physicists say that everything is energy vibrating at particular frequencies, yet noone has defined energed in what exactly it even is. Also, I have asked myself wether forces like dark energy are energy as well and if so what forces and energy really are at the most fundamental level. It seemed weird to me that forces are something that pushes or pulls something, but what pushes or pulls things? What do those forces consist of? What really are they? I hope this video gives me some answers! I love the way Neil is communicating science and making it fun, despite it being hard, like Einstein once said: „Genius is making complex ideas simple, not making simple ideas complex“
Simpler. Energy (mass) is a local excitation (available ready potential) on the fabric of spacetime. If potentials of electron field pass a certain density, they effect the field to focus its growth with similar curvature to its mass equivalent, with various critical mass equivalents as it grows. Mass itself in reverse, is potential energy. Edit- simplistic analogy for forces would be the peaks of any field has higher potential of its force than its valleys, and field upon field upon fields, create their own push and pull on the spacetime in possible interactions, or independently from each other. The mother force is time. It creates the duality of matter and amplifies the force by its field created by its duality to occupy space. Nothing but a massless particle can exist without time. Meaning of what we believe is a singularity. I’m not a scientist. Just a wannabe studying to explain it to myself without paradoxes to real science for a very long time building on a Simplistic foundation so I can grasp it
Energy is something that can be converted. It has the potential to "move things" or to heat things because it is stored in some way and is then converted to do work. At a fundamental level, yes everything is vibrating and is converting or storing energy. Dark Energy is simply energy we don't understand. As is Dark Matter; Dark Matter is gravity we dont understand. We can measure it, it has an effect on our perception of the universe but we can't really say what it is or where it comes from. And yes, Einstein was a genius because he understood reality in very simple terms.
Energy is the Noether charge of time-translation symmetry. What this means is that energy is an arbitrary number we can label a system with that can, under certain conditions, be conserved (the number is held constant).
Your explanations of the different types of energy and how they function is great. I was also delighted to learn that all energy comes from the sun. But the question still remains in my mind: what is energy? What is it made of?
Energy is the translatable output of entropy (a process). Entropy can be thought of as a measure of the dispersal of energy. It measures how much energy has been dispersed in the process. The flow of any energy is always from high to low. Hence, entropy always tends to increase. So you need to discuss both, because they work together.
Well i think it must be some kind of ability to take energy from things which do have energy, until the entropy of the system reaches its highest level.
Chuck is exactly like my brother. I am usually quite serious in meeting with our company. But just the stuff that comes out of his brain is hilarious and his timing is perfect. I don't even stop him now; he's a great icebreaker and makes everyone more interested in our meetings. I see why they have Chuck there, defiantly an asset to the show.
Neil didn't mention that Energy cannot be created or destroyed it is only transformed. Which makes me think how maybe literally everything in existence is related more or less because of this. Crazy thought. And it also leads me to think that after death maybe our energy in our bodies transforms into who knows what. Maybe there is something completely unimaginable after death. This Universe is really mysterious for sure with all these phenomenons.
Simple. After death, we return to the ecosystem. The kind of energy you're alluding to isn't the physical kind, more like 'spiritual'. And that's Pandora's box
Neil is smarter than you give him credit for. He didn't talk about the conservation of energy ... because *energy is **_not_** conserved!* 😵 • Due to the expansion of the universe, Dark Energy is getting created at an ever increasing rate. Created. From. Nothing. There's nothing being transformed into this form of energy. • At quantum scales, on the other hand, virtual particles are also getting created all the time - _out of nothing!_ And when they annihilate each other - _it results in nothing!_ They don't transform into mass or other forms of energy.
Wonderful episode..The human mind has trouble figuring out none physical phenomenon like energy.The same applies to time.Till now we can't totally understand time.
A circular ballet dance that starts from vibration in the nucleus of an atom to produce frequency which accumulate to produce energy to create stability. What an eternal dance. Thanks Neil.
Consumption and transportation (i.e. walking, climbing, swimming, hunting and other forms of harvesting the wild (e.g. fruit) etc.) were interactions with energy preceding our first literal ignitions.
Far from our first. Walking, seeing, breathing, mitochondrial biogenesis, or even [not] freezing to death. Every movement uses and converts energy. We are constantly interacting with energy, even when we're sitting still. Even non-living things are interacting with energy as they gain and lose heat, reflect light, etc.
The story about cannons was a little wrong. It was actually cannon manufacturers when boring out the the cannon wondering why the metal continuously got hotter, enough to melt the tool. I believe it was Benlaman Thompson (aka Lord Rumford) who studied this phenomenon.
One of the easiest ways to tell when someone is peddling charlatanry, pseudoscience or misinformation is how they constantly misuse or misrepresent the concept of energy.
As much as I enjoy Star talk this time I heard a good description of what energy does and the forms it can take, but I still don’t know what it is. I don’t know that anyone does. Why is there something rather than nothing is one question to which I don’t know that I have ever heard a definitive answer. Why that something moves is another, similar question whose answer still seems vague. Such answers may, as Dr. Tyson has pointed out many times, simply be beyond the reach of humanity’s limited intellectual capabilities. But it is sure fun to hear it talked about.
I'm certainly no expert here, but I believe a photon doesn't actually "travel". As an observer we see it as travelling and we can measure it; but from the photon's point of view it doesn't move through time or space. A photon comes into existence a million light years away and it appears here instantaneously, dissolving into our retina as energy. From everything I've read I think that's right and it explains why the speed of light is the fastest speed there is.
Photons are massless particles that travel at the speed of light. They do not rely on matter, potential energy or particles to transfer energy, but rather propagate through a vacuum by electromagnetic radiation. The reason the roller coaster was able to converter potential energy to kinetic and Vice versa was because it had mass. This is why they are able to travel vast distances through space without losing energy. As they travel, photons cannot be absorbed or scattered by other particles as they have no electric charge or magnetic moment. This means that they can travel incredible distances through space virtually unimpeded. In essence, a photon's energy is conserved because it is not exchanged with any other particle or medium. This is what makes them so unique and allows them to travel vast distances through the vacuum of space without losing any energy.
@@DanoTV209 this sounds like a great reply but it isn’t. The statement is actually false. If it was just true, there would be no such thing as a light year. So saying that a photon doesn’t travel is incorrect. In fact, saying that “as soon as it appears, we see it”…that’s a false statement because you are talking about us and the place it was created, not the photon. Of course, if you could truthfully talk about the photon’s perspective, as soon as it is created, we see it. It is everywhere and no where at once. But what a photon IS depends on how we perceive it, not on how it perceives itself. That’s why the Big Bang shouldn’t make sense to most people if they actually think about it. How can everything come from nothing? Well the phrase “come from” is the issue because you can’t “come from” anywhere if there is no time.
@@oidbio2565 Actually the reason photons can travel forever - without losing any energy - is the fact that photons travel at the speed of light. Special relativity tells us that clocks slow down as velocity is increased until at the speed of light, time ceases to flow. Without the passage of time, entropy doesn't come into play. A photon coming from billions of light years away, makes the journey in an instant from the photon's point of reference.
Just picked up Cosmic Queries: Star Talk's Guide to Who We Are, How We Got Here and Where We're Going by N.D.T. with James Trefil....totally excited to start reading this!
Energy = going 2-3 mins in the bedroom then taking a drink of water or Gatorade and nailing another 30 mins! That’s energy my friends. Gotta get that first one out of the way then come back “slanging” ENERGY. Lmao sorry Chuck and NDG just my definition
I had learned back in college classes that all processes (weather, winds, tectonics, etc) that occur on Earth are driven by the sun. Now I have an even better understanding of how wide the sun's effect is on life on our planet. So, I suppose there's some benefit to paying respect to the sun for our lives and gives deeper meaning to yoga's "sun salutation".

Neil, as usual, is correct on the broader points. Which leaves me scraping the bottom for nits. Of which, as usual, there are several:
• The concept of _phlogiston_ was invented to explain fires-that is, the why's and how's of burning aka combustion. Obsolete now; it's been replaced by chemistry.
• The concept of _caloric_ was invented to explain heat flow. Obsolete now; it's been replaced by thermodynamics.
• Classical thermodynamics explains concepts like thermal energy, heat flow, temperature, entropy etc. without resorting to atoms and molecules.
• Atoms were postulated several millennia ago by Greek philosophers such as Democritus. However, they became accepted by modern science only from the 19th century onwards, due to work by Dalton, Einstein _et al._
• Thermodynamics can be reformulated in terms of atoms and molecules, giving us _statistical thermodynamics._ Classical thermodynamics emerges from it at macroscopic scales (akin to how classical mechanics and classical electromagnetism emerge from quantum mechanics).
• And finally, an internal combustion engine gets hot because *there's literally combustion happening inside it!* 😜

Big ups to the person editing in the graphics and additional footage. Thanks!
Always love watching these two together. Great chemistry between them. Pun intended 😂
they are just exchanging energy.
That's quite Punny🤣🤣🤣
And biology
Yeah, they have great potential for entertainment! 😅
@@1tapsocietyOTS good one little buddy 🙂
I was hoping to hear something about entropy too, because there's such a close connection between energy, heat and entropy. It's also worth explaining the 'heat death of the universe' and of course how it's connected to energy and entropy. But maybe next time.
entropy "disorder" is actually the energy (in the form of heat) that is released in such spontaneous reactions. He just didn't use the word entropy.
@@akakakaka287 Partially yes, but I find your explanation a bit incomplete, we must talk about a system if we talk about entropy. Calling it spontaneous heat (or waste heat) is too simple. The reason why I would gladly hear more about these, is because most people don't understand the connection between energy, heat and entropy. It would be so nice to hear a great explanation, it's effects on the whole universe (heat death as mentioned), maybe even something about black holes and Hawking radiation too.
@@akakakaka287 I agree with @Mikáci's last elaboration. Entropy is much (MUCH!) more complicated. For one, it is not "disorder" as is often mischaracterized ("disorder" is an over-simplification & partly inaccurate).
Hoping there's a 2nd+3rd video: energy, entropy, MassEnergy (since mass/energy are the same thing), how energy transfers ("moves"), equilibrium ("heat death" & Hawking radiation)... many complex aspects.
@graceonoja-iv6ex Boring scammer.
That‘s great explanations! Yet the question still remains: What is even energy and where does it come from?
lol Watch it again. 😉
Energy (force) is spin, which creates a vibration, the force is created by the presence of matter.
Force shapes matter and matter generates force. They are two equal opposites that are connected, they exist because of each other and the universe is shaped by their shape & interactions.
Matter has physical limits, force does not. Force is able to pass through itself & matter, matter cannot pass through matter.
Dark energy is our lack of understanding of this, dark energy describes something that we can’t see with our eyes, this is force.
There is no concept called odd or even energy. Everything is natural 🤣
You know what energy is, you pay for it every month when you pay your electric bill.
Energy = Power x Time.
If you have 120 volt outlet, and you plug in a bulb that draws .5 amps of current, that means the bulb draws 60 Watts of power. If you keep the light on for 1 hour that is 60 Watt-Hours of ENERGY. Keep it on for 10 hours and that is 600 Watt-hours of ENERGY.
If you had a bulb that draws 50 amps of current that means the bulb draws 6,000 Watts of power. If you keep the light on for 1 hour that is 6,000 Watt-hours of ENERGY. If you leave the light on for 10 hours that is 60 KiloWatt-Hours of ENERGY (60,000 Watt-Hours of ENERGY.)
That's what energy is, an accounting system of Watts and time, which is POWER x TIME. ;)
@@rmeyers2021 yes, that is one of many forms of energy.
Neil I am over here trying to focus on work!! Then I go and get a notification from you. Now I have to stop what I’m doing to listen wait to what you have to say!!😅
Love to see this editing going forward, 1080p with some videos referencing what is being talked about to make it easier to imagine what it would look like, amazing !
Thank you for your feedback!
I can (and often do) watch Neil content all day. I just wish that I could have had him as a teacher back when I was in high school, as he makes learning a pleasurable experience 👏👏
You realize that at his core, Snake in DeGrasse Tyson believe that the world would be better off if half of you were 'gone', right? You can get back to fellating the enemy of your children now, if you like.
he wouldnt be able to maintain this kind of energy for an entire semester. nobody could. he only gives you the highlights and headlines . the most interesting bits of science. its an unrealistic bar to be set for other educators. behind every cool science factoid or concept theres tons of boring, mundane, repetitive, mind numbing sessions of memorization and pedestrian grunt work involved.
@@ShortFuseFighting Yeah, I came to this realisation the hard way.
People (including me) think that they understand the concepts being talked about at a higher percentage than they actually do (the Dunning Kruger Effect) it makes it seem fun because its been oversimplified. However when you actually read about the topic and have to put in the hard work, memorise and think you understand the really almost monumental jobs that have to be done by teachers to teach children 80%+ of whom have no interest or the true capacity to understand these things on a more fundamental level. I've heard hundreds of hours worth of information about black holes but in reality I cant do any of the math or physics but understand the very simplified basic concept and factoids because they seem cool to me.
You and about a hundred thousand other kids
@@ShortFuseFighting Lol what? There are plenty of professors out there who stay excited for the class topic the whole semester. Also idk why that Ambrosia guy is talking about dunning-kruger and all that stuff when OP didn't even say anything about their perceived level of intelligence on the subjects lmao. All they said was "I love Neil because he makes learning fun." I think you guys need to pull the stick out of your black holes if you know what I'm saying
I’m a retired fireman. We used to use steam conversion in confined attic fires- taking advantage of the 1700 times expansion from water to steam!!! And good on us for finding a way to use the byproduct of boiling water!!!
"I have another explainer bubbling up inside me" "Are you sure that's an explainer" Lord Nice you are a godsend 😭
This man shows you how fascinating physics can be... If only we would get the same kind of vibe and lessons from the teachers in school, the world would probably be a better place...
As a 13-year educator I can say a couple things about this. First, this quality of teaching sometimes DOES happen in schools. And teachers who teach like this in any subject are often denigrated by their administrators and colleagues for being “too cool” or “too informal.” Why? Because this style of teaching isn’t in the textbook. It comes from deeply understanding the field of study he’s talking about. Deep understanding isn’t as valuable to our educational systems as is obedience and conformity. It’s super frustrating.
I had two burned out Science teachers in high school, luckily the last one, Physics was not and that's when I decided to go for double major of Electrical Engineering and Computer Science in college.
@@juanjoperez7537these are heavy, lots of math and analytical energy, I will go bonkers 😅

Thanks Chuck, I feel better about myself. I am full of potential.
Gotta love it when this video drops right when we are covering the chapter on energy in Bio. 👍🏻
Hope this is a valuable study aid!
I shared this video with my brother a former cannon cocker with the US Army, just to hear him vent when Neil said "back when cannons were a popular tool in warfare". I had to pause the video for 20 minutes while he explained the evolution of the cannon from the Napoleon era cannons all the way to the modern M777 howitzers that he used to crew. Listening to him get triggered was worth the delay.
"where did the log get its energy?" Oh wow that question brings back great memories of watching Richard Feynman's "Fun to imagine"
Oh so good! Educational, fun, and funny! Love it!! Thank you so much Neil and Chuck!!
The ending was perfect!
Energy comes from energy. And the first energy comes from nothingness. And nothingness comes from magic. I assume.
- What is energy, really? ...i'm still learning the answer to this question... it seems like a mysterious sort of "thing"... like phlogiston or Caloric... but i know there's an even deeper understanding of energy that is not crystal clear to science yet... 2:20
- the Calorie & the Joule can measure energy... but i don't think they "define" it 10:19
- Also, i believe Chuck has much potential 11:31
Misleading title. This is more about "what are the different kinds of energy we encounter and how are they stored and converted?" The question of what energy is is not covered.
Since I started to see this channel I have learned so much.... 👏
I started looking for videos to explain what energy is a few days ago, so this is a happy coincidence. But I still haven't found the answer, because mostly people are explaining the various forms it can take. But I am beginning to suspect that we still don't have a clue what it _is._
Life force & consciousness are also energy which is converted from the things we consume.
All energy has spin. Even the circle of life. Even life & death is simply energy changing form. Your force is eternal.
All energy, no matter what form it takes, has the same pattern of behaviour. A cyclic, duality of force that has a pair of vortices rotating in equal and opposite directions, exactly why for everything there is an equal opposite.
You can see the spin in trees growing out of the ground, tornadoes, waves at the beach etc. etc. you can observe the force moving through all matter around you, I have countless examples of what it looks like, and I can share enough of my perspective to answer some of your questions.
@@Justin-gv3lp it is spin. A vibration that is caused by spin. The vibration is caused by the presence of matter, and the vibration shapes matter, which in turn shapes the vibration. They are two equal opposites, one is matter, the other is not, but they are connected.
@@Justin-gv3lp keep wondering, there's a whole universe to wonder about. Saying energy is the ability to do work is like saying water is what's required to turn a water wheel, it doesn't say what water is. Particles are the form of energy that fascinates me most, because it's energy that's kind of resonating eternally, like it's moving really fast but mostly in one place.
“Energy” is actually just an artificial concept to simplify physical formulas. It’s a math trick.
Strictly speaking, there is no such thing as energy in nature. Or, as Neil put it in the video, it’s nothing you can point a finger at.
Energy is everything. It's the reason there is something rather than nothing.
My understanding of energy is basically motion. Kinetic energy is motion in action. Potential energy is motion that can become action in motion. This seems to hold true for everything, from vibrating atoms to zooming protons to propagating EM waves. It's all physical motion.
There are different kinds of energy, though I'm not enough of a physicist to explain it well.
Electromagnetic, has properties different from other kinds...
Like electromagnetic can cancel out (block?) electromagnetic energy of the same frequency...
Unfortunately, I cannot articulate a good rebuttal 😅
Too much for this bio guy lol
@Tragoudistros.MPH what you mean is a wave and a 180-degree shifted wave of the same magnitude and frequency. Their peaks and valleys cancel. But it's still motion. And unless they're traveling together, the original propagation will continue past the point of incidence.
So the energy in our universe is finite. Every thing we in our universe from matter to photons was created in the big bang. So if energy can't be destroyed then if our universe keeps e
Expanding does the energy dissipate over the larger space?
That literally one theory about how the universe will end. and it’s called the Big freeze
This was brilliant. Thanks guys for another fantastic, and informative episode. 👍👍

Potential puke to kinetic puke.
Explainers make my day. Fr I’ve used these more in real life than any of my 14 years of schooling (basics aside)
I have always asked me what energy even is, because physicists say that everything is energy vibrating at particular frequencies, yet noone has defined energed in what exactly it even is. Also, I have asked myself wether forces like dark energy are energy as well and if so what forces and energy really are at the most fundamental level. It seemed weird to me that forces are something that pushes or pulls something, but what pushes or pulls things? What do those forces consist of? What really are they? I hope this video gives me some answers! I love the way Neil is communicating science and making it fun, despite it being hard, like Einstein once said: „Genius is making complex ideas simple, not making simple ideas complex“
Simpler.
Energy (mass) is a local excitation (available ready potential) on the fabric of spacetime. If potentials of electron field pass a certain density, they effect the field to focus its growth with similar curvature to its mass equivalent, with various critical mass equivalents as it grows. Mass itself in reverse, is potential energy.
Edit- simplistic analogy for forces would be the peaks of any field has higher potential of its force than its valleys, and field upon field upon fields, create their own push and pull on the spacetime in possible interactions, or independently from each other. The mother force is time. It creates the duality of matter and amplifies the force by its field created by its duality to occupy space. Nothing but a massless particle can exist without time. Meaning of what we believe is a singularity.
I’m not a scientist. Just a wannabe studying to explain it to myself without paradoxes to real science for a very long time building on a Simplistic foundation so I can grasp it
Energy is something that can be converted. It has the potential to "move things" or to heat things because it is stored in some way and is then converted to do work. At a fundamental level, yes everything is vibrating and is converting or storing energy.
Dark Energy is simply energy we don't understand. As is Dark Matter; Dark Matter is gravity we dont understand. We can measure it, it has an effect on our perception of the universe but we can't really say what it is or where it comes from.
And yes, Einstein was a genius because he understood reality in very simple terms.
@@rezadaneshi it's flawed but it was worth reading
Energy is the Noether charge of time-translation symmetry. What this means is that energy is an arbitrary number we can label a system with that can, under certain conditions, be conserved (the number is held constant).

Neil and Chuck for 2024
Your explanations of the different types of energy and how they function is great. I was also delighted to learn that all energy comes from the sun. But the question still remains in my mind: what is energy? What is it made of?
Haha.. This episode had great energy between Neil and Chuck 😏
I am loving watching this guy. I understand better so many things
"Abstract human thinking" is the only thing that consumes less energy than it procuces ... in my oppinion . Great explainer with lots of "potential"
that is wrong by the way, our brain uses 20% of our body's energy, and anyways what energy does "Abstract human thinking" produce?
@@DendrocnideMoroidesit produces imense "potential" energy😊
Energy is the translatable output of entropy (a process).
Entropy can be thought of as a measure of the dispersal of energy. It measures how much energy has been dispersed in the process. The flow of any energy is always from high to low. Hence, entropy always tends to increase. So you need to discuss both, because they work together.
Better question, what's NOT energy ?
Dark energy
Well i think it must be some kind of ability to take energy from things which do have energy, until the entropy of the system reaches its highest level.
Me on the couch. 😂
🤷♂️
What's not nuclear energy?
Chuck is exactly like my brother. I am usually quite serious in meeting with our company. But just the stuff that comes out of his brain is hilarious and his timing is perfect. I don't even stop him now; he's a great icebreaker and makes everyone more interested in our meetings. I see why they have Chuck there, defiantly an asset to the show.
Excellent talk guys! Now we need part 2 on entropy 😊
i can listen to Neil all day. He is really good with explaining physics principles
Neil didn't mention that Energy cannot be created or destroyed it is only transformed. Which makes me think how maybe literally everything in existence is related more or less because of this. Crazy thought. And it also leads me to think that after death maybe our energy in our bodies transforms into who knows what. Maybe there is something completely unimaginable after death. This Universe is really mysterious for sure with all these phenomenons.
The law of conservation of mass states that matter cannot be created or destroyed not energy.
Simple. After death, we return to the ecosystem. The kind of energy you're alluding to isn't the physical kind, more like 'spiritual'. And that's Pandora's box
Neil is smarter than you give him credit for. He didn't talk about the conservation of energy ... because *energy is **_not_** conserved!* 😵
• Due to the expansion of the universe, Dark Energy is getting created at an ever increasing rate. Created. From. Nothing. There's nothing being transformed into this form of energy.
• At quantum scales, on the other hand, virtual particles are also getting created all the time - _out of nothing!_ And when they annihilate each other - _it results in nothing!_ They don't transform into mass or other forms of energy.
@@nickbisson8243 But in nuclear reactions, matter _is_ destroyed. So clearly, the _"Law of Conservation of Mass"_ is false, isn't it?
@@nHans nope either atoms are fused together to make heavier elements like in the sun or they're split with fission
I love the art prints in each of their homes……and listening to Sir Neil talk about science.
Wonderful episode..The human mind has trouble figuring out none physical phenomenon like energy.The same applies to time.Till now we can't totally understand time.
A circular ballet dance that starts from vibration in the nucleus of an atom to produce frequency which accumulate to produce energy to create stability. What an eternal dance. Thanks Neil.
Fire was our first interaction with energy, other than hit it harder it's not dead yet.
Consumption and transportation (i.e. walking, climbing, swimming, hunting and other forms of harvesting the wild (e.g. fruit) etc.) were interactions with energy preceding our first literal ignitions.
Far from our first. Walking, seeing, breathing, mitochondrial biogenesis, or even [not] freezing to death. Every movement uses and converts energy. We are constantly interacting with energy, even when we're sitting still. Even non-living things are interacting with energy as they gain and lose heat, reflect light, etc.
I love listening to this guy, and I’m currently reading and loving his Starry Messenger book,…

I like the new opening sound along with that animation
Neil & Chuck -gold as always -thanks guys!
The story about cannons was a little wrong. It was actually cannon manufacturers when boring out the the cannon wondering why the metal continuously got hotter, enough to melt the tool. I believe it was Benlaman Thompson (aka Lord Rumford) who studied this phenomenon.

The both of you together makes science funny😂
As much as I enjoy Star talk this time I heard a good description of what energy does and the forms it can take, but I still don’t know what it is. I don’t know that anyone does. Why is there something rather than nothing is one question to which I don’t know that I have ever heard a definitive answer. Why that something moves is another, similar question whose answer still seems vague. Such answers may, as Dr. Tyson has pointed out many times, simply be beyond the reach of humanity’s limited intellectual capabilities. But it is sure fun to hear it talked about.
I want to learn everything in life from Neil and Chuck. What a wonderful world it would be.

Please talk about the energy of a photon and how photons can travel light years with the same energy
I'm certainly no expert here, but I believe a photon doesn't actually "travel".
As an observer we see it as travelling and we can measure it; but from the photon's point of view it doesn't move through time or space. A photon comes into existence a million light years away and it appears here instantaneously, dissolving into our retina as energy. From everything I've read I think that's right and it explains why the speed of light is the fastest speed there is.
Photons are massless particles that travel at the speed of light. They do not rely on matter, potential energy or particles to transfer energy, but rather propagate through a vacuum by electromagnetic radiation. The reason the roller coaster was able to converter potential energy to kinetic and Vice versa was because it had mass. This is why they are able to travel vast distances through space without losing energy.
As they travel, photons cannot be absorbed or scattered by other particles as they have no electric charge or magnetic moment. This means that they can travel incredible distances through space virtually unimpeded.
In essence, a photon's energy is conserved because it is not exchanged with any other particle or medium. This is what makes them so unique and allows them to travel vast distances through the vacuum of space without losing any energy.
@@DanoTV209 this sounds like a great reply but it isn’t. The statement is actually false. If it was just true, there would be no such thing as a light year. So saying that a photon doesn’t travel is incorrect. In fact, saying that “as soon as it appears, we see it”…that’s a false statement because you are talking about us and the place it was created, not the photon.
Of course, if you could truthfully talk about the photon’s perspective, as soon as it is created, we see it. It is everywhere and no where at once. But what a photon IS depends on how we perceive it, not on how it perceives itself.
That’s why the Big Bang shouldn’t make sense to most people if they actually think about it. How can everything come from nothing? Well the phrase “come from” is the issue because you can’t “come from” anywhere if there is no time.
@@oidbio2565 Actually the reason photons can travel forever - without losing any energy - is the fact that photons travel at the speed of light. Special relativity tells us that clocks slow down as velocity is increased until at the speed of light, time ceases to flow. Without the passage of time, entropy doesn't come into play. A photon coming from billions of light years away, makes the journey in an instant from the photon's point of reference.
@@AL_EKs that’s not true. There is no entropy of Energy
I loved Chuck's impression of Charles Boyer.
The cosmos is made of pure energy. Energy is eternal. It has always been and will always be. The thoery (not just my theory) of infinity.
Well said.
"Ever wonder what energy is?
*15 minutes of listing the behaviors of energy instead of ever actually defining energy*"
Energy is vibration! It comes out of the polarization of space-time!
Chuck, love the jokes
Just picked up Cosmic Queries: Star Talk's Guide to Who We Are, How We Got Here and Where We're Going by N.D.T. with James Trefil....totally excited to start reading this!
Energy = going 2-3 mins in the bedroom then taking a drink of water or Gatorade and nailing another 30 mins! That’s energy my friends. Gotta get that first one out of the way then come back “slanging” ENERGY. Lmao sorry Chuck and NDG just my definition
You’re talking about slangin dat D ! On a science show…. 😂
I never thought about when energy was a scientific measurement and not just a generic concept. Super Cool!

You two are awesome. Great educational content. Thanks for your efforts 🙂!
ur awesome little rick 🙂
I had learned back in college classes that all processes (weather, winds, tectonics, etc) that occur on Earth are driven by the sun. Now I have an even better understanding of how wide the sun's effect is on life on our planet. So, I suppose there's some benefit to paying respect to the sun for our lives and gives deeper meaning to yoga's "sun salutation".
This is soooo beautiful, and i kove how you’ve added infographics
