Quantum Harmonic Oscillator

Some trajectories of a harmonic oscillator (a ball attached to a spring) in classical mechanics (A-B) and quantum mechanics (C-H). In quantum mechanics, the position of the ball is represented by a wave (called the wavefunction), with real part shown in blue and imaginary part in red. Some of the trajectories, such as C,D,E,F, are standing waves (or "stationary states"). Each standing-wave frequency is proportional to a possible energy level of the oscillator. This "energy quantization" does not occur in classical physics, where the oscillator can have any energy.

Space, Time, and Indiscernibles in Leibnitz

If space is real separately from substances, then two substances can be indiscernibles and be in different locations - this entails a paradox.
But, if space is a 'projection' of internal properties of substances, then two apparently indiscernible substances are really different by virtue of those properties which are perceived as spatial relations.


The properties of every monad in the universe, just like the properties within any one monad, are all interconnected n a vast network of explanation, according to the law of sufficient reason. But what is the reason for the whole set of monads - what explains the existence and nature of the universe itself?

Unicursal hexagram

The unicursal hexagram is a hexagram or six-pointed star that can be traced or drawn unicursally, in one continuous line rather than by two overlaid triangles. The hexagram can also be depicted inside a circle with the points touching it.

Aleister's unicursal hexagram

Aleister Crowley's adaptation of the unicursal hexagram placed a five-petaled rose (symbolizing the Divine), in the center, the symbol as a whole making eleven (five petals of the rose plus six points of the hexagram).

Shamanic trance (N. Drury 1982)

As the trance condition is induced there is a withdrawal of consciousness from the everyday world and a shift toward the inner world of reverie, thoughts and images. In the case of the shaman it is not just that trance is involved, for this condition is also common in the case of mediums, epileptics and schizophrenics. In the person of the shaman we have one who is able to control the trance dimension and who is able to explore the realms of the cosmos which his altered state of consciousness opens for him.

Schrödinger's cat

Schrödinger's cat is a thought experiment, usually described as a paradox, devised by Austrian physicist Erwin Schrödinger in 1935. It illustrates what he saw as the problem of the Copenhagen interpretation of quantum mechanics applied to everyday objects. The scenario presents a cat that might be alive or dead, depending on an earlier random event. Although the original "experiment" was imaginary, similar principles have been researched and used in practical applications. The Cat paradox is also often featured in theoretical discussions of the interpretation of quantum mechanics.
