Practical Quantum Realization of the Ampere from the Elementary Charge
One major change of the future revision of the International System of Units is a new definition of the ampere based on the elementary charge e. Replacing the former definition based on Ampère’s force law will allow one to fully benefit from quantum physics to realize the ampere. However, a quantum realization of the ampere from e, accurate to within 10−8 in relative value and fulfilling tracea...
متن کاملAMPERE Newsletter
Several thousands of million tons of wastes are generated worldwide every year. Of these, organic solid wastes have the potential to partially satisfy the production of chemicals, whilst the environmental impact can be minimized and the sustainability of the processes increased compared to those based on fossil resources. However, these wastes are complex due to their high heterogeneity, and ne...
متن کاملA non local Monge-Ampere equation
We introduce a non local analog to the Monge-Ampere operator and show some of its properties. We prove that a global problem involving this operator has C solutions in the full space.
متن کاملThe Ampere and Electrical Standards
This paper describes some of the major contributions to metrology and physics made by the NIST Electricity Division, which has existed since 1901. It was one of the six original divisions of the National Bureau of Standards. The Electricity Division provides dc and low-frequency calibrations for industrial, scientific, and research organizations, and conducts research on topics related to elect...
متن کاملAmpere Tension and Newton’s Laws
A recent paper (Robson and Sethian 1992, hereafter termed R&S) reports new experimental results on the old problem of Ampere tension. The null results they achieved led them to conclude the nonexistence of Ampere longitudinal forces, interpreted as forces differing observably from those predicted by the Lorentz force law. Their bibliography confirms that the subject is controversial. As with an...
