Red Letter Day

On July 3rd, 2014 I discovered the Master Angle, a particular configuration of horizontally-disposed slope and a particularly angled backboard which (I believe) permits an object to roll UPWARD.

This is possible because H - V > V (H).

This is possible, I have proved (or believe I have proved) in very particular configurations (I believe the equation is not enough by itself, but rather there must be a particular ratio of weight placement between the horizontal and the vertical, including consideration of the height of the marble relative to the horizontal slope, affecting the angularity of the backboard).

I have tested with a level, and the bubble is close to the middle, but sometimes indicates upward slope. The optimal case is shown in my video, Master Angle / Reverse Gravity 1.

In the following video

I think I have evidence that a spherical weight can roll upwards under certain very specialized conditions:

I measured from the floor on the right and left edges of the marble's movement, and it appears that the right side was higher than the left. Mixed results with a level, although clearly when measured on a partial contingency, the slope is upwards.

My explanation for the theory is that the forwards angularity of the marble is steeper than the difference between the horizontal slope and the vertical slope, corresponding to the two pieces of cardboard underneath the marble. A very special case, if true.
