How the Phantom Traffic Jam Occurs (Experimental Evidence)
All this shows is a hard braking vehicle can create a chain reaction that forces other cars in traffic to stop. How to prevent them? First thing is, just keep your distance. And if you see a space open up in front of you, don't rush to fill it.

Principle behind Hydraulic Power

Technically speaking, there is very little power being demonstrated. The hydraulic pressure generates a significant force, which raises the bricks by about an inch. Moreover, it does so slowly. Force times velocity is power. Force is great, power is note.

    I have very serious reservations about the use of the word “infinity”. Infinity doesnt close the loop. For practical applications….. ok maybe, but in reality the “closed loop” seems more like a plugged gap that doesnt describe the intersection correctly. I have no clue about math though so what the hell do I know. 😅

      Yeah! That makes no sense to me. Using Taylor series with x=1 ends at e, I believe. Euler may have stumbled on this another way when looking at compound interest. 1+1/1!+1/2!+1/3!+1/4!+1/5!... If I was gonna calculate e by hand, I would do this.. If we use calculus to discover relations that we need for calculus, it's cheating.

    Ouh god,what he calling that formula.That what he doing is correct.But his explain of"e" isn't correct.And that formula is called Indenitty.Because he using E,the name of phonex and his started Name .And He what doing,it was for his added negative number"1" but how he get 0.That isn't correct and E we got for fuse(cosX)+i(sinx) and we got E.But how we can fuse cosX and sin X.so we have the function of fuse positive and Negative numbers.Positive number is 2,5,8,11... And negative 3,4,6,7,9,11... And we got e(i,π) but we got 3 so we need to over his Formula for negative 1 to be equal zero.And you over his indenitty.

    • @putinscat1208
      @putinscat1208 Рік тому

      Euler calculated e using something like Taylor series with x = 1. As for sin, cos, you need to take the Taylor series approximations for them and relate to Taylor series for e^(ix). I used UA-cam to see this in action. It would almost be nice if math teaches went thru the history of these things.

    for those who dont get how its supposed to work: you'll have to measure the distance from your pov to your object on the ground, and then measure the angle between your line of sight to the object and the ground with the "altimeter" from the video. with some trigonometry you can calc the height of the object.

  • @jaywhited1174
    @jaywhited1174 2 роки тому

    how does that measure altitude? Do you know what an altimeter is? Altimeters measure changes in atmospheric pressure as the plane climbs or descends. It has no reference to the ground or even sea level. When correctly set, the altimeter reads height above mean sea level, known as MSL. The altimeters found in aircraft are barometric sensitive altimeters.

    Matter and dark matter: Galaxies rotate too fast but are not torn apart. What causes galaxies from flying apart? By Csaba A. Bodor. Last edited April 4, 2022 gravity, they say, is associated with baryonic matter and with dark matter. EVEN better: gravity is associated with the mass of baryonic matter and the SPEED of motion of the former. Dark matter gravity is caused by ordinary baryonic matter in motion! Some speculate that a mysterious substance called "dark matter" must exist which holds the galaxies together. I submit that this dark matter is nothing more than ordinary matter which is in motion around the galactic core and around the billions of stars. Matter that is in motion presses against the aether of space (to those stuck in the Einstein loop, it is also called space-time) and the aether presses back in the form of gravity and the moving matter also creates time dilation. This gravity could be the missing gravity that is holding galaxies together. There are two types of time dilation. One is caused by the aether's affect on matter and the other is the aether's affect on speeding matter or electromagnetic "waves". As matter, of any size, displaces the aether, the aether presses back with what we call gravity. This gravity presses on the matter affecting it's "being". All activity of matter os slowed down. The cesium in a cesium clock runs slower because the nuclear particles of cesium are slowed down. The clock therefore runs slower. Radioactive elements all run slower; their half-lifes are increased. Their internal subatomic particles run slower. The microprocessors and other perts of computers all run slower. Our brains are affected also and our minds work slower. Everything near and about that matter that intruded into the realm that belongs to the aether runs slower. As one moves away from the mass of that large mass we live on the press of the aether becomes less and the particles and pieces of the atoms will run faster since the gravity created by the aether slowly lessons as we move away from the large mass. That cesium clock runs faster. The half-life of the radioactive elements changes and its "time" is affected. Humans living further from the mass of the earth will perceive time as running faster. Computers will likewise run faster. Time dilation that is caused by motion comes about because of the motion of matter or electromagnetic waves through the aether. A photon traveling at "C" pushes against the aether, the aether pushes back and creates gravity. The internal properties of the photon or even matter are slowed down. As humans move through the aether at great speeds we perceive the time runs slower for us. Time dilation. For a photon, because it is traveling at "C", time actually stops. The photon experiences NO time. The photon cannot travel faster than "C" because the aether sets the speed limit by pushing against the photon's motion through the aether. This is also why matter cannot go faster than "C". When light goes through a gas or a liquid it is forced to slow down and give part of its energy to the gas or liquid which eats into the photon's ability to move at "C". The energy given up heats up the gas or liquid or can even affect the atom's motion; even give off its own "light". We do not see a photon as it travels through the aether. When the photon or other electromagnetic wave hits matter, it slows down and even stops. As the photon does this the photon's energy turns into visible light. PS: Dark matter gravity and dark energy is nothing more than the gravity created by the matter inside a galaxy moving about, pressing against the aether, and then the aether presses back with gravity caused by that motion. All the electromagnetic waves (photons) bouncing around the galaxy also add to the missing gravity that some say is caused by dark matter. Nothing dark (unknown) about it. Look to the movement of matter and electromagnetic waves (including photons).

      No, by definition the derivative function is df/dx = 1/(deltax) *(f(x+deltax) - f(x)) . So when he subtracts 0 (ln1) he can replace all that by the derived of lnx with 1 as the base point, and turns out all that is 1.

    • @jacobstrength3945

      In a sense, yes! The natural log and logarithm properties were discovered and defined before e. All of these properties were provably true, and they knew e was some constant that had its famous properties, they just didn’t know what that constant was equal to. This video is in deriving how to calculate that constant.

    It turns out one needs to watch the whole video to understand where e comes from. He actually starts out constructing how one obtains the derivative of any exponential expression and "discovers" e in the process, i.e he "backs into" what e is by determining its existence, although its exact value is not known, and can't be because its irrational. He then uses e because of its mathematical properties, not its numerical value. In the end he demonstrates a mathematical way to approximate e's numerical value derived from its previously noted properties. A very elegant lecture and worth watching in its entirety.
