Inconsistency of the Wolf sunspot number series around 1848 [PDF]

open access: yes, 2013
Aims. Sunspot number is a benchmark series in many studies, but may still contain inhomogeneities and inconsistencies. In particular, an essential discrepancy exists between the two main sunspot number series, Wolf (WSN) and group (GSN) sunspot numbers ...

The solar differential rotation in the 18th century

open access: yes, 2012
The sunspot drawings of Johann Staudacher of 1749--1799 were used to determine the solar differential rotation in that period. These drawings of the full disk lack any indication of their orientation.

Interaction-free measurements by quantum Zeno stabilisation of ultracold atoms [PDF]

open access: yes, 2015
Quantum mechanics predicts that our physical reality is influenced by events that can potentially happen but factually do not occur. Interaction-free measurements (IFMs) exploit this counterintuitive influence to detect the presence of an object without ...
