De Indorum Anno Solari Astronomico, Leonhard Euler Dec 1737

De Indorum Anno Solari Astronomico, Leonhard Euler

All Works by Eneström Number

This work is an appendix following two other appendices in a book by Euler's friend and St. Petersbrg Academy colleague T. S. Bayer, Historia regni Graecorum Bactriani (History of the Bactrian kingdom of the Greeks). The original appendices were written by a Danish missionary in Tranquebar, C. T. Walther ("The Indian Doctrine of Time," pp. 145-190), and by Bayer himself, based on his correspondence with Walther and other Tranquebar missionaries ("Supplement to the Indian Doctrine of Time," pp. 191-200). Euler's contribution appears immediately after these.

Observationes De Theoremate Quodam Fermatiano Aliisque Ad Numeros Primos Spectantibus, Leonhard Euler

All Works by Eneström Number

Euler shows that the fifth Fermat number, 225 +1 = 4,294,967,297, is not prime because it is divisible by 641, though he does not give any clues about how he discovered this fact. He also tacks on a few "theorems" but says that he does not yet know how to prove them.

Studying Properties Of Xenon Doped Argon And Developing Optical Simulation Techniques For The Legend Collaboration, A Neutrinoless Double Beta Decay Experiment, Neil Christopher Mcfadden Dr

Physics & Astronomy ETDs

Neutrinoless double beta decay is a hypothesized lepton-number-violating process in which two neutrons decay to two protons, producing two electrons but no electron antineutrinos. The LEGEND collaboration will search for this decay in 76Ge. To improve the argon active veto for LEGEND-1000, xenon doped argon was explored as an alternative active volume. Simulations using argon doped with 10 ppm xenon and pure liquid argon were used to predict the light yield from cosmic muons in a 100 liter cryogenic vessel. The simulations predicted that xenon doping would yield 1.83+/-0.02 more light, while an increase of 1.81+/-0.05 was measured. From …
