A clock network for geodesy and fundamental science

A clock network for geodesy and fundamental science

Leveraging the unrivalled performance of optical clocks as key tools for geo-science, for astronomy and for fundamental physics beyond the standard model requires comparing the frequency of distant optical clocks faithfully. Here, we report on the comparison and agreement of two strontium optical clocks at an uncertainty of 5 × 10(-17) via a newly established phase-coherent frequency link conne...

Art and science: geodesy in materials science.

A 3-dimensional model based on a molecular structural recipe having some unique and unexpected shape characteristics is demonstrated. The project was originally initiated to satisfy the aesthetic creative impulse to build a 3-dimensional model or sculpture. Further scientific investigation explained some important nanoscale structural observations that had been seen many years beforehand and mi...

Fundamental Limits on Network Clock Synchronization by Nikolaos Markos

We present fundamental impossibility results on clock synchronization in wireline or wireless networks, and sharply characterize what is feasible. We consider a network of n nodes with affine clocks, with one node designated as a reference. Each other node’s clock is described by a skew (relative speedup with respect to the reference clock), and an offset at time 0 (say) with respect to the ref...

passivity in waiting for godot and endgame: a psychoanalytic reading

this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
