history of the measurement of mass by Mind Map: history of  the measurement of mass

1. Summary of mass concepts and formalisms

1.1. In classical mechanics, mass has a central role in determining the behavior of bodies. Newton's second law relates the force F exerted in a body of mass M to the body's acceleration α: F=ma

1.1.1. Goal 1

1.1.2. Goal 2

1.2. Additionally, mass relates a body's momentum p to its velocity v: p=mv

1.2.1. Session Rule 1

1.2.2. Session Rule 2

1.3. and the body's kinetic energy K to its velocity

1.4. In special relativity, relativistic mass is a formalism which accounts for relativistic effects by having the mass increase with velocity

1.5. Since energy is dependent on reference frame (upon the observer) it is convenient to formulate the equations of physics in a way such that mass values are invariant (do not change) between observers, and so the equations are independent of the observer. For a single particle, this quantity is the rest mass;

1.6. Define Action Points

2. history

2.1. Following the Council of Trent, Pope St Pius V, concerned with some innovations and improper accretions in the Order of the Mass in some areas, reviewed the Roman Missal. When he was finished, he declared that all priests of the Latin Church throughout the World must use the Roman Missal he prepared when they said Mass. They could not add a single word to it, or choose to leave a single word out, without his authority. Only those rites which had already been established for more than two centuries before the date he promulgated the new Missal were allowed to say Mass differently (eg, the Milanese Rite, the Dominican Rite).
