The Xingming guizhi (性命圭旨, Principles of Inner Nature and Vital Force) is a comprehensive Ming dynasty (1368-1644) text on neidan ("internal alchemy") self-cultivation techniques, which syncretistically quotes sources from the Three teachings of Daoism, Confucianism, and Buddhism (particularly the Yogachara school), and is richly illustrated with over fifty illustrations that later ...
The microcosmic orbit should be viewed in the context of a variety of Taoist exercises and techniques designed to purify the body physically, mentally and spiritually, improve health and longevity, and prepare the way for meditation, and also including other techniques such as the macrocosmic orbit which means circulating energy into the other ...
It is described as lead(II,IV) oxide, or structurally 2PbO·PbO 2, and is the best-known mixed valence lead compound. Lead dioxide is a strong oxidizing agent, capable of oxidizing hydrochloric acid to chlorine gas. [77] This is because the expected PbCl 4 that would be produced is unstable and spontaneously decomposes to PbCl 2 and Cl 2. [78]
Dilithium (Li 2) exists (two covalently bonded lithium atoms); but something else is referred to in fiction. In Star Trek, dilithium occurs in crystal form and serves as a controlling agent in the matter-antimatter reaction cores used to power the faster-than-light warp drive. In the original series, dilithium crystals are rare and cannot be ...
[1] [2] For many centuries, it was the most sought-after goal in alchemy. The philosopher's stone was the central symbol of the mystical terminology of alchemy, symbolizing perfection at its finest, divine illumination, and heavenly bliss. Efforts to discover the philosopher's stone were known as the Magnum Opus ("Great Work"). [3]
[2] In speaking of the lower of the three energy centers, the term dantian is often used interchangeably with the Japanese word hara (腹; Chinese: fù) which means simply "belly." In Chinese, Korean, and Japanese traditions, it is considered the physical center of gravity of the human body and is the seat of one's internal energy .
Schematic of energy levels involved in two photons absorption. In atomic physics, two-photon absorption (TPA or 2PA), also called two-photon excitation or non-linear absorption, is the simultaneous absorption of two photons of identical or different frequencies in order to excite an atom or a molecule from one state (usually the ground state), via a virtual energy level, to a higher energy ...
newton meter squared per kilogram squared (N⋅m 2 /kg 2) shear modulus: pascal (Pa) or newton per square meter (N/m 2) gluon field strength tensor: inverse length squared (1/m 2) acceleration due to gravity: meters per second squared (m/s 2), or equivalently, newtons per kilogram (N/kg) magnetic field strength
