Indult Mass [17] Tridentine Latin Mass [18] or Traditional Latin Mass [19] [20] (both abbreviated as TLM), or simply the Latin Mass [21] [b] Old Order of Mass (Latin: Vetus Ordo Missae) or simply the Vetus Ordo [22] Preconciliar liturgy [23] The preconciliar Ambrosian Rite has been called the Extraordinary Form of the Ambrosian Rite. [24]
The Tridentine Mass, [1] also known as the Traditional Latin Mass [2] [3] or the Traditional Rite, [4] is the liturgy in the Roman Missal of the Catholic Church codified in 1570 and published thereafter with amendments up to 1962.
The law of conservation of mass can only be formulated in classical mechanics, in which the energy scales associated with an isolated system are much smaller than , where is the mass of a typical object in the system, measured in the frame of reference where the object is at rest, and is the speed of light.

The earliest surviving account of the celebration of the Eucharist or the Mass in Rome is that of Saint Justin Martyr (died c. 165), in chapter 67 of his First Apology: [2]. On the day called Sunday, all who live in cities or in the country gather together to one place, and the memoirs of the apostles or the writings of the prophets are read, as long as time permits; then, when the reader has ...
Mass–energy equivalence states that all objects having mass, or massive objects, have a corresponding intrinsic energy, even when they are stationary.In the rest frame of an object, where by definition it is motionless and so has no momentum, the mass and energy are equal or they differ only by a constant factor, the speed of light squared (c 2).
The first law of thermodynamics is a formulation of the law of conservation of energy in the context of thermodynamic processes.The law distinguishes two principal forms of energy transfer, heat and thermodynamic work, that modify a thermodynamic system containing a constant amount of matter.
Total energy is the sum of rest energy = and relativistic kinetic energy: = = + Invariant mass is mass measured in a center-of-momentum frame. For bodies or systems with zero momentum, it simplifies to the mass–energy equation E 0 = m 0 c 2 {\displaystyle E_{0}=m_{0}c^{2}} , where total energy in this case is equal to rest energy.
