# Degrees Of Freedom

Quantum Superposition-- is a fundamental principle of quantum mechanics. It states that, much like waves in classical physics, any two (or more) quantum states can be added together ("superposed") and the result will be another valid quantum state; and conversely, that every quantum state can be represented as a sum of two or more other distinct states.

This newly advanced prosthetic limb is the result of a collaboration between the University of Pittsburgh and Johns Hopkins University. The arm has the ability to accurately detect vibration,temperature, contact with objects and degree of pressure. It also has up to 27 degrees of freedom of moment, making it far more than a cosmetic addition.

De SItter and hyperbolic spaces. Modern view Degrees of freedom In the year 2000 Tom Banks and Willy Fischler discovered that the mass density parameter Ω is determined as the inverse of the number N of degrees of freedom. Refer to the figures below: the curvature parameter Ω0 encodes the system density, a relation between mass + energy and volume. But, the volume strictly depends on the number of degrees of freedom. And that’s why the amount of degrees of freedom are since then…
