Energy can only do things when theres different concentrations in different areas, for example a cold spot and a warm spot. You can use this to do whatever you want, make kinetic movement with an engine or catalyze a chemical reaction. But entropy and inneficiency means that the energy will become useless once it mixes. The cold and hot spots will become just warm, and there will be no way to use that energy to make pressure differences or anything else because in order for _anything_ to happen, there must be a flow of energy, from high to low or low to high. But when it is all average, there stops being high or low.
@leomadero5624 жыл бұрын
Another way to describe it is to stir a cup of water. There is energy in that glass, shown by the water's movement. But with entropy, the water stops swirling. The real life problem is that this is the state the universe is in. For the cup, you can just stir it to give it more energy, but you can't just give more energy to the universe.

Time doesn't slow down for you when you're moving fast, your "proper time" is always the same. Your time just appear to be moving slower from the perspective of a second observer outside your inertial reference frame. Edit: Then if you change directions and accelerate back towards the second observer, their clock will be moving a lot faster from your perspective. When you finally complete your journey and return to the same frame as the second observer, they will have aged a lot more than you.

Arvin, You do NOT know how thankful I am for this video. I've always been interested in physics since my childhood, but gave it up later as a rather foolish act of rebellion against the forceful insistence of my parents that I become a doctor. (They themselves are both doctors and I am from an Indian family, so you can imagine what pressure I was in) Anyhow, since the education system in our country is structured such that all science graduates must go on to become doctors, I gave up the sciences, and having done so, I pursued Law at University. These details about my life, youth and interests will no doubt bore you, but the reason I state these is that as a practicing lawyer who never had this interesting of a science teacher as you clearly demonstrate yourself to be at any period of my school life, I feel forever indebted and grateful to you from the bottom of my heart for so artfully piquing my long lost interest in science once again, to the point where I have now decided to expand my knowledge in the sciences in the duration of these rather unexpected days of pandemic where I am mostly at home with little to no clients in my practice.

This video truly lives up to its title, condensing an enormous amount of information on physics into a 15-minute video is no easy task, but the creator has done an admirable job. The explanations are concise and to the point, making it easy to grasp even for those with little prior knowledge on the subject. The visual aids used in the video are excellent, they help to explain the concepts in a way that text alone cannot. It's a valuable resource for students, educators and anyone looking for a quick and easy way to understand the basics of physics. I highly recommend It. As an engineer who has always been passionate about math and physics, I was intrigued by modern physics, despite neither relativity nor quantum mechanics were part of any course syllabus at my university. I studied these subjects on the side and found them really inspiring, I would go as far as to say that they gave me a novel perspective on life itself. That prompted me to create some online courses on Udemy on Quantum Mechanics, Quantum Field Theory, special and General Relativity. It’s not my job of course, but I love talking about these topics ans showing the "intution" behind the mathematics.

Answer Gravy: This isn’t part of the question, but if you’ve taken intro physics, you’ve probably seen the equations for kinetic energy, momentum, and acceleration in a uniform gravitational field (like the one you’re experiencing right now). But unless you’re actually a physicist, you’ve probably never been freaked out by seeing a Lagrangian work. This gravy is full of calculus and intro physics. The “action”, S\left(\vec{x}(t) ight), is a function of the path a system takes, \vec{x}(t)=(x_1(t),x_2(t),x_3(t))=(x(t),y(t),z(t)). More specifically, it’s the integral of the Lagrangian between any two given times: S\left(\vec{x}(t) ight)=\int_{t_1}^{t_2}\mathcal{L}\left(\vec{x}(t),\dot{\vec{x}}(t) ight)dt where t1 and t2 are the start and stop times, \vec{x} is a path, \dot{\vec{x}} is the time derivative (velocity) of that path, and \mathcal{L} is some given function of \vec{x} and \dot{\vec{x}}. If you want to chose a path that extremizes (either minimizes or maximizes) S, then you can do it by solving the Euler-Lagrange equations: \frac{\partial\mathcal{L}}{\partial x_i}=\frac{d}{dt}\frac{\partial\mathcal{L}}{\partial \dot{x}_i} This is called the Euler-Lagrange equations (plural) because this is actually several equations. Each different variable (x1=x, x2=y, x3=z) tells you something different. In regular ol’ calculus, if you want to find the value of x that extremizes a function f(x), you solve \frac{df}{dx}=0 for the value x. Using the Euler-Lagrange equations is philosophically similar: to find the path that extremizes S, you solve \frac{\partial\mathcal{L}}{\partial x_i}=\frac{d}{dt}\frac{\partial\mathcal{L}}{\partial \dot{x}_i} for the path \vec{x}(t). The Lagrangian from earlier, for a free-falling object near the surface of the Earth, is: \mathcal{L}=\frac{1}{2}m\left|\dot{\vec{x}}(t) ight|^2-mgz(t)=\frac{1}{2}m\left[\left(\dot{x}(t) ight)^2+\left(\dot{y}(t) ight)^2+\left(\dot{z}(t) ight)^2 ight]-mgz(t) For z: \begin{array}{l}\frac{\partial\mathcal{L}}{\partial z}=-mg\\[2mm]\frac{\partial\mathcal{L}}{\partial \dot{z}}=m\dot{\vec{z}}(t)\\[2mm]\frac{d}{dt}\frac{\partial\mathcal{L}}{\partial \dot{z}}=m\ddot{\vec{z}}(t)\end{array} So the E-L equation says: m\ddot{\vec{z}}(t)=-mg or \ddot{\vec{z}}(t)=-g In other words, “everything accelerates downward at the same rate”. Doing the same thing for x or y, you get \ddot{\vec{x}}(t)=\ddot{\vec{y}}(t)=0, which says “things don’t accelerate sideways”. Both good things to know. You wanna be even slicker, note that this Lagrangian is independent of time. That means that \frac{\partial\mathcal{L}}{\partial t}=0. Therefore, applying the chain rule: \begin{array}{rl}\frac{d\mathcal{L}}{dt}=&\frac{\partial\mathcal{L}}{\partial t}+\sum_i\left(\dot{x}_i\frac{\partial\mathcal{L}}{\partial x_i}+\ddot{x}_i\frac{\partial\mathcal{L}}{\partial \dot{x}_i} ight)\\[2mm]=&\sum_i\left(\dot{x}_i\frac{\partial\mathcal{L}}{\partial x_i}+\ddot{x}_i\frac{\partial\mathcal{L}}{\partial \dot{x}_i} ight)\end{array} But we have the E-L equations! Plugging those in: \begin{array}{rl}=&\sum_i\left(\dot{x}_i\frac{d}{dt}\frac{\partial\mathcal{L}}{\partial \dot{x}_i}+\ddot{x}_i\frac{\partial\mathcal{L}}{\partial \dot{x}_i} ight)\\[2mm]=&\sum_i\frac{d}{dt}\left(\dot{x}_i\frac{\partial\mathcal{L}}{\partial \dot{x}_i} ight)\end{array} And therefore: \frac{d}{dt}\left(\sum_i\dot{x}_i\frac{\partial\mathcal{L}}{\partial \dot{x}_i}-\mathcal{L} ight)=0 This thing in the parentheses is constant (since it never changes in time). In the case of \mathcal{L}=\frac{1}{2}m\left[\left(\dot{x} ight)^2+\left(\dot{y} ight)^2+\left(\dot{z} ight)^2 ight]-mgz we find that this constant thing is: \begin{array}{rl}&\sum_i\dot{x}_i\frac{\partial\mathcal{L}}{\partial \dot{x}_i}-\mathcal{L}\\[2mm]=&\left[\dot{x}\frac{\partial\mathcal{L}}{\partial \dot{x}}+\dot{y}\frac{\partial\mathcal{L}}{\partial \dot{y}}+\dot{z}\frac{\partial\mathcal{L}}{\partial \dot{z}} ight]-\mathcal{L}\\[2mm]=&\left[\dot{x}(m\dot{x})+\dot{y}(m\dot{y})+\dot{z}(m\dot{z}) ight]-\left[\frac{1}{2}m\left[\left(\dot{x} ight)^2+\left(\dot{y} ight)^2+\left(\dot{z} ight)^2 ight]-mgz ight]\\[2mm]=&\frac{1}{2}m\left[\left(\dot{x} ight)^2+\left(\dot{y} ight)^2+\left(\dot{z} ight)^2 ight]+mgz\end{array} Astute students of physics 1 will recognize the sum of kinetic energy plus gravitational potential. In other words: this is a derivation of the conservation of energy for free-falling objects. A more general treatment can be done using Noether’s Theorem, which says that every symmetry produces a conserved quantity. For example, a time symmetry (\mathcal{L} doesn’t change in time) leads to conservation of energy and a space symmetry (\mathcal{L} doesn’t change in some direction) leads to conservation of momentum in that direction.
