Notes:
१. 1795 की तिथियों से उपरोक्त उपसर्ग प्रयोग में लाए जारहे हैं, जबसे मीट्रिक प्रणाली प्रयोग में आई थी । अन्य तिथियाँ आवश्यक रूप से प्रथम प्रयोग की नहीं रहीं हैं, बलकि CGPM के समझौते द्वारा मान्यता की तिथि हैं जो कि 1889 में हुआ था ।
2. 2. "मैक्रॉन" शब्द को CGPM नें १९४८ में अनुमोदित किया, पर १९६७-६८ में उसे रद्द कर दिया।

  • Whenever the force does work, potential energy is lost.

क्वांटम यांत्रिकी (Quantum Mechanics)[संपादित करें]

Postulate 1: State of a system A system is completely specified at any one time by a Hilbert space vector.
Postulate 2: Observables of a system A measurable quantity corresponds to an operator with eigenvectors spanning the space.
Postulate 3: Observation of a system Measuring a system applies the observable's operator to the system and the system collapses into the observed eigenvector.
Postulate 4: Probabilistic result of measurement The probability of observing an eigenvector is derived from the square of its wavefunction.
Postulate 5: Time evolution of a system The way the wavefunction evolves over time is determined by Shrodinger's equation.
