A physicist ran the numbers on a black hole through you
When a physicist runs the numbers on a black hole passing through a human body, the result is not a cinematic vaporization but a precise, almost clinical portrait of how gravity would pull a person ...
When analyzing a system, internal forces (forces between objects within the system) do not affect the system's overall motion ...
Representing Variables: In algebra, the gray unit can also represent a variable, such as 'x' or 'y'. In this case, the size and shape of the gray unit don't necessarily correspond to a specific ...
Abstract: It is shown that a simple active oscillating circuit with memristor yields quite complicated two-parameter bifurcation diagrams. When two (out of three) parameters of the circuit change ...
Horizontal lines run left to right, parallel to the horizon, with slope 0 and equation y = k. Vertical lines run top to bottom, perpendicular to the horizon, with undefined slope and equation x = k.
