I explore two logical possibilities for the discretization of time, termed ``instantaneous" and ``smeared". These are found by discretizing a continuous theory, and the resulting structure of configur...

When addressing the notion of proper time in the theory of relativity, it is usually taken for granted that the time read by an accelerated clock is given by the Minkowski proper time. However, there ...
Telling time from analog and digital clocks: A multiple-route account

Does the naming of clocks always require conceptual preparation? To examine this question, speakers were presented with
analog and digital clocks that had to be named in Dutch using either a relative...
Einstein's Clocks and Langevin's Twins
Einstein's Clocks Langevin's Twins History and Philosophy of Physics
2012/5/28
In 1905 Einstein presented the Clock Paradox and in 1911 Paul Langevin expanded Einstein's result to human observers, the "Twin Paradox." I will explain the crucial difference between Einstein and Lan...
Rydberg Spectroscopy in an Optical Lattice: Blackbody Thermometry for Atomic Clocks
Rydberg Spectroscopy Optical Lattice Blackbody Thermometry Atomic Clocks

Abstract: We show that optical spectroscopy of Rydberg states can provide accurate {\em in situ} thermometry at room-temperature. Transitions from a metastable state to Rydberg states with principal q...

A New Rb Lamp Exciter Circuit for Rb atomic clocks and Studies on Transition from Ring to Red mode
Rb Lamp Exciter Circuit Rb atomic clocks

In this paper we describe the development of novel RF exciter circuit for electrode less Rb lamp. The lamp exciter circuit is a RF oscillator with a a new configuration operating at 60 to 65 MHz freq...
Flavour-Oscillation Clocks and the Geometricity of General Relativity
general relativity geometry clocks
2009/11/20
I look at the ‘flavour-oscillation clocks’ proposed by D.V. Ahluwalia,
and two arguments of his suggesting that such clocks might behave in a way
that threatens the geometricity of general relativit...

New very high-speed 82.5-GS/s sampling IC and its incorporated burst-mode CDR compliant for 10G-EPON is presented. The 82.5-GS/s sampling CDR successfully achieved a high pulse-width distortion tolera...
Optical Lattice Clocks with Non-Interacting Bosons and Fermions

2009/6/1
We report on frequency comparison of two optical lattice clocks based on fermionic 87Sr trapped in 1D optical lattice and bosonic 88Sr in 3D one. We discuss that these two lattice clock configurations...
Galileo noted in the 16th century that the period of oscillation of a pendulum is almost independent of the amplitude. However, such a pendulum is damped by air friction. The latter may be viewed as r...
Watching the Clocks: The Role of Food Stamp Recertification and TANF Time Limits in Caseload Dynamics
