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?

Photoelectric effect

In physics, Compton scattering is a type of scattering that X-rays and gamma rays undergo in matter. The inelastic scattering of photons in matter results in a decrease in energy (increase in wavelength) of an X-ray or gamma ray photon, called the Compton effect. Part of the energy of the X/gamma ray is transferred to a scattering electron, which recoils and is ejected from its atom (which becomes ionized), and the rest of the energy is taken by the scattered, "degraded" photon.

Heisenberg's gamma ray microscope

Heisenberg's gamma-ray microscope for locating an electron (shown in blue). The incoming gamma ray (shown in green) is scattered by the electron up into the microscope's aperture angle θ. The scattered gamma-ray is shown in red. Classical optics shows that the electron position can be resolved only up to an uncertainty Δx that depends on θ and the wavelength λ of the incoming light.

The tree of life

The qabalistic tree of life, important in the magical order A∴A∴ as the degrees of advancement in are related to it.

Tychonian system

Diagram depicting the basics of the Tychonian geocentric system. Basically, the objects on blue orbits (the Moon and the Sun and the fixed stars) revolve around the Earth. The objects on orange orbits (Mercury, Venus, Mars, Jupiter, and Saturn) revolve around the Sun. All is surrounded by a sphere of fixed stars (though they are fixed only with respect to each other, for the sphere revolves around the earth). The system is essentially geocentric, though everything except for the moon and the fixed stars and the earth centre itself revolves around the Sun.


5. The Black Cross or Central Tablet.
The upper and lower sides are equally attributed to Spirit.
The left-hand sides to the element of the file, in this order from left to right: Spirit, Air, Water, Earth, Fire. The right-hand sides to the element of the rank in this order: Air, Water, Earth, Fire.


The Shew-stone, a crystal which Dee alleged to have been brought to him by angels,was then placed upon this table, and the principal result of the ceremonial skrying ofSir Edward Kelly is the obtaining of the following diagrams, Plates III.-VIII.
He symbolized the Four-Dimensional Universe in two dimensions as a squaresurrounded by 30 concentric circles (the 30 Æthyrs or Aires) whose radii increase in a geometrical proportion.
