Measurement of the Planck constant at the
Researchers at the National Institute of Standards and Technology (NIST) have measured the value of the Planck constant to be h = 6.626 069 934(89)× 10−34J s (relative standard uncertainty 13 × 10−9). The result is based on over 10 000 weighings of masses with nominal values ranging from 0.5 kg to 2 kg with the Kibble balance NIST-4. The uncertainty has been reduced by more than twofold relativ...
متن کاملDeterminism and the Gravitational Planck Constant
A discussion is given of the uncertainty principle in view of the introduction of a Gravitational Planck Constant. The need for such a gravitational constant is shown first. A reduced electromagnetic Planck constant and the analogous reduced gravitational Planck constant are defined as h/e and H/m respectively. An attempt is made to reconcile the quantum uncertainty concepts with a deterministi...
متن کاملA new spectrometer to measure the molar Planck constant
A new spectrometer to measure the molar Planck constant. The SI-unit kilogram is scheduled to be re-defined within the next years. In the attempt to link it to a fundamental constant of nature – namely the Planck constant or the Avogadro constant – some discrepancies appeared. A direct determination of the molar Planck constant helps to trace this discrepancy. Such a determination can be done w...
متن کاملA Universal Constant for Exponential Riesz Sequences
The aim of this paper is to study certain correlations between lower and upper bounds of exponential Riesz sequences, in particular between sharp lower and upper bounds, where we show that the product of the sharp bounds of an exponential Riesz sequence is bounded from above by a universal constant. The result is applied to the norms of coefficient and frame operators and their inverses.
متن کاملA Universal Constant for Semistable Limit Cycles
We consider one–parameter families of 2–dimensional vector fields Xμ having in a convenient region R a semistable limit cycle of multiplicity 2m when μ = 0, no limit cycles if μ / 0, and two limit cycles one stable and the other unstable if μ ' 0. We show, analytically for some particular families and numerically for others, that associated to the semistable limit cycle and for positive integer...
