E. J. Marey--physiologist and first cinematographer.

J. E. Shaw

1866 he used to get up every morning at six in order to get from Bath to his classes in Bristol punctually. In 1869 he went to Edinburgh to complete his course, and qualified there in 1872. He was House Physician at the Edinburgh Royal Infirmary, a Fellow of the Edinburgh Botanical Society and President of the Royal Medical Society of Edinburgh. In 1875 he returned to Clifton and two years late...

The e + e − → J/ψD ¯D, J/ψD ¯D ∗ reactions with dynamically generated resonances

In two recent reactions by Belle producing DD̄ and DD̄∗ meson pairs, peaks above threshold have been measured in the differential cross sections, possibly indicating new resonances in these channels. We want to study such reactions from the point of view that the D meson pairs are produced from already known or predicted resonances below threshold. Our study shows that the peak in the DD̄∗ product...

Physiological apparatus in the Wellcome Museum. 1. The Marey sphygmograph.

ONE cHARAcrEsTIc of the new physiology of the nineteenth century was the graphic representation of body function.1 It provided a means whereby transient phenomena could be translated into a permanent record and studied at leisure. The dynamics of the cardiovascular system were particularly susceptible to such techniques. In 1860 E. J. Marey (1830-1904) devised the first convenient sphygmograph ...

J/ψ Electromagnetic Production at e+e− Colliders

Within the framework of QED we investigate the inclusive J/ψ production at ee colliders. It is expected to be as a further test to the charmonium production mechanisms and QED. We find that at the energies of CESR, BEPC, and TRISTAN (e.g. 4.0GeV ≤ √s ≤ 60GeV ), the contributions of the concerned electromagnetic processes to the J/ψ inclusive production are great, even dominant, thus they greatl...
