    10:32 (r+s)²=r²+d² 2rs+s²=d² 2rs=d²-s²=(d-s)(d+s) s=(d/r -s/r)(d+s)/2 s=(tanθ - λ)q, θ is clockwise, ...(1) q=(d+s)/2=(1+s/d)d/2=½(1+sinθ')d ...(1i) Let AB be the straight line from the top of the circle to where s meets the 2nd r line. We see that: rθ>|AB|. For example, say that: rθ/|AB|=1+rφ/|AB|, for some φ<θ. => r(θ-φ)=|AB|. But, also: |AB|²=s²+d²-2sd·cosα, where α is opposite line AB, so cosα≈s/d. Therefore: (rθ)²>s²+d²-2sd·cosα Actually: r²(θ-φ)²=s²+d²-2sd·cosα Using 1 & 1i with the eqn above, we have: r²(θ-φ)²=(tanθ -λ)²q²+d²-2(tanθ -λ)qd·cosα Divide all by r²: (θ-φ)²=¼(tanθ -λ)²(1+sinθ')²tan²θ+tan²θ -(tanθ -λ)(1+sinθ')tan²θ·cosα => (((θ-φ)/tanθ)² -1)/((tanθ -λ)(1+sinθ')) =¼(tanθ -λ)(1+sinθ')-cosα If we say θ≈θ' and make it small so that sinθ≈θ, then: (((θ-φ)/θ)² -1)/(θ -λ)(1+θ))≈¼(θ -λ)(1+θ)-cosα => ((-2(φ/θ)+(φ/θ)² )/(θ -1+1 -λ)(1+θ)) ≈¼(θ -1+1 -λ)(1+θ)-cosα => ((-2(φ/θ)+(φ/θ)² )/(θ² -1+1 -λ+θ -λθ)) ≈¼(θ² -λ+θ-λθ)-cosα θ and λ=s/r are both small => ((-2(φ/θ)+(φ/θ)² )/(-λ+θ))≈¼( -λ+θ)-cosα Now multiply by θ => ((-2(φ)+(φ²/θ))/(-λ+θ))≈¼( -λ+θ)θ-θ·cosα Small θ & λ =>((-2(φ)+(φ²/θ))/(-λ+θ))≈ -θ·cosα As θ decreases, cosα decreases & α approaches ½π, therefore θ·cosα is small. =>((-2(½π)θ+(¼π²))/(-λ+θ)) ≈0 => -2(½π)θ+(¼π²)≈ 0 => θ≈ ¼/π radians Also, (θ-φ)=|AB|/r , |AB| will approach d. => φ≈ ¼/π -d/r ≈ ¼/π -tan(¼/π) ≈0. Therefore r/4π ≈ d, which kinda indicates the validity of the relevant laws of Poisson & Gauss. i.e Gravity flux area = 4πd², although this is meant to be part of a sphere... The trajectory is QUANTIZED!!! If r= 320,000km then d≈ 25,464 km which is about 2 times Earth's diameter !! We see that the area 4πd² is also the area of a rectangle equal to r·d, so each gravity impulse from Earth that affects the moon must be acting as the Earth moves from one position to the next. That distance is equivalent to about 1.93 minutes of travel relative to the MW Galaxy (v=220km/s), or 14mins 15secs relative the Sun (v=29.78km/s). The speed of the moon relative Earth is about v=1km/s (slightly over), so the time taken for my particular d to be traversed is: t= d/v > 25464 secs ≈ 7.07 hours. In that time, the Earth moves about 7.58*10⁵ km relative the Sun and 5.6*10⁶ km relative to MWG. Therefore the impulse it sends to the moon must be as it traverses about 59 and 437 Earth diameters respectively. As d≈r/4π , we have 2rs+s²≈r²/4π² Thus s≈ -r±½√(4r² -4r²/4π²)=r(-1±√(1-1/4π²)) Take r= 320,000km , then s≈ -4078.8km or s≈ 63.6*10⁴ km. The only value that makes sense is the negative value, and so s≈ -4.08*10³ km. s/d & 90°-α≈atan(s/d)° are then about -0.16 & -9.1°, so that α≈80.9° to 83.5°. Perhaps someone could carry on this analysis and work out if Earth's orbit around the Sun or MWG has more affect on the moon's trajectory. Interesting stuff.

    I wonder what the spacecraft was doing all the while they were running about, must have been pitching about, especially with them being all bunched up at one side. It would be interesting if spacex could get a larger diameter tank up to low orbit so they could try spinning it instead, see how sick they all got! I haven't read what it felt like, if it was like running up a slope or constantly tumbling over.

    That's the way to lecture - notice the humour which converts to understanding. Without any effort, it is easy to see change in momentum requires a force to promotes that change. That is the way Aristotle viewed science which after all is Naturay Science. This lecture could have been done 3,000 years ago. Great demonstration Dan. I shall include in the training (as an engineer) in future, so also; thanks for the lesson.

    Why is it that the bouncy side provides more force into the 2x4 rather than the firm side? It seems to me that the bouncy side would provide less force into the 2x4 because it maintains kinetic energy by bouncing off. While the firm side does not recoil as much and because of this it seems that it should distribute its kinetic energy into the 2x4 better than the bouncy side.

    If the ball hits and sticks, it transfers momentum to the board. If the board were to "throw" the ball away from it, that would transfer momentum to the board. The bouncing ball is like the board is catching AND throwing it back. I go to great lengths to show this here: kzread.info/dash/bejne/d6SVpNyPn8aZf7g.html

    Time travel is not possible because time is absolute and is the same for all inertial frames! The proof for this is that nearfield light has been experimentally measured to be infinite, and deriving Relativity using infinite speed nearfield light yields Galilean Relativity. See papers below for proof. This can easily be seen by inserting c=infinity into the Lorentz Transform, yielding the Galilean Transform. where time is the same for all inertial observers and no Relativistic effects are observed. Also only the present exists, the past is gone, and the future has yet to be. So if a moving object is observed with farfield speed c light, then Relativistic effects will be observed. But if the frequency of the light is reduced such that instantaneous nearfield light is used, then no Relativistic effects will be observed. So with the flick of a switch, Relativistic effects can be made to vanish. Since Time and Space are real and are independent of the frequency of the light used to observe it, then the effects of Relativity are not real and are simply an optical illusion. Many researchers have independently verified nearfield light is instantaneous, and it has been measured in different ways. In addition theoretical analysis using Maxwells equations agree perfectly with these results. These results show that the phase speed, group speed, and front speed (information speed) are all instantaneous in the nearfield and reduce to the speed of light c in the farfield after about one wavelength. Some may say that many experiments have proven Relativity, so how can Relativity be wrong? Well no experiment can prove an experiment right. They can only provide evidence toward a theory. But one experiment can absolutely prove a theory wrong, and the experimental measurement that nearfield light is instantaneous proves Relativity is wrong. The evidence here shows that it describes only an optical illusion. Since General Relativity is based on Special Relativity, then it has the same problem. A better theory of Gravity is Gravitoelectromagnetism which assumes gravity can be mathematically described by 4 Maxwell equations, similar to to those of electromagnetic theory. It is well known that General Relativity reduces to Gravitoelectromagnetism for weak fields, which is all that we observe. Using this theory, analysis of an oscillating mass yields a wave equation set equal to a source term. Analysis of this equation shows that the phase speed, group speed, and information speed are instantaneous in the nearfield and reduce to the speed of light in the farfield. This theory then accounts for all the observed gravitational effects including instantaneous nearfield and the speed of light farfield. The main difference is that this theory is a field theory, and not a geometrical theory like General Relativity. Because it is a field theory, Gravity can be then be quantized as the Graviton. Lastly it should be mentioned that this research shows that the Pilot Wave interpretation of Quantum Mechanics can no longer be criticized for requiring instantaneous interaction of the pilot wave, thereby violating Relativity. Consequently the Pilot wave interpretation should become the preferred interpretation of Quantum Mechanics due to its deterministic simplicity.
