James MacCullagh 1809 − 1847Springer Science and Business Media LLC - Tập 35 - Trang 113-122 - 2010
T. D. Spearman
The purpose of this paper is to set out in general terms the life of the Irish
mathematician and theoretical physicist James MacCullagh, in its context of
place and time. MacCullagh, who was born two hundred years ago in 1809, was best
known for his significant contributions to optics and light propagation, and in
particular towards the development of a model of the aether, a central
scientific co... hiện toàn bộ
History of solar oblateness measurements and interpretationSpringer Science and Business Media LLC - Tập 36 - Trang 407-436 - 2011
J. -P. Rozelot, C. Damiani
The story of the solar oblateness begins in the pre-relativity days when an
explanation of the observed advance of Mercury’s perihelion was searched for.
Then, examination of historical records during the first decade of the twentieth
century shows clearly a strong effort to measure the solar shape. Results show
discrepancies, due on one hand, to the fact that physical statements in the
solar case... hiện toàn bộ
Charles Galton Darwin’s 1922 quantum theory of optical dispersionSpringer Science and Business Media LLC - Tập 45 - Trang 1-23 - 2020
Benjamin Johnson
The quantum theory of dispersion was an important conceptual advancement which
led out of the crisis of the old quantum theory in the early 1920s and aided in
the formulation of matrix mechanics in 1925. The theory of Charles Galton
Darwin, often cited only for its reliance on the statistical conservation of
energy, was a wave-based attempt to explain dispersion phenomena at a time
between the the... hiện toàn bộ
Lord Kelvin on fluid mechanicsSpringer Science and Business Media LLC - Tập 37 - Trang 75-114 - 2012
Alex D.D. Craik
William Thomson, Baron Kelvin of Largs, was the best-known British scientist of
his day, who made fundamental contributions to many areas of physics and
engineering. Though his life and work have been much studied, his contributions
to fluid mechanics have received far less attention that those in heat,
electricity, magnetism, geophysics, “ether theory” and telegraphy. After a
general introduction... hiện toàn bộ
Searching for a response: the intriguing mystery of Feynman’s theoretical reference amplifierSpringer Science and Business Media LLC - Tập 44 - Trang 331-347 - 2019
Vincenzo d’Alessandro, Santolo Daliento, Marco Di Mauro, Salvatore Esposito, Adele Naddeo
We analyze Feynman’s work on the response of an amplifier performed at Los
Alamos and described in a technical report of 1946, as well as lectured on at
the Cornell University in 1946–47 during his course on Mathematical Methods. The
motivation for such a work was Feynman’s involvement in the Manhattan Project,
for which the necessity emerged of feeding the output pulses of counters into
amplifier... hiện toàn bộ
The fifth force: A personal historySpringer Science and Business Media LLC - Tập 40 - Trang 385-467 - 2015
Ephraim Fischbach
On January 6, 1986, a paper written by our group appeared in Physical Review
Letters entitled “Reanalysis of the Eötvös Experiment”. In that Letter we
reanalyzed a well-known 1922 paper by Eötvös, Pekár, and Fekete (EPF) which
compared the accelerations of samples of different composition to the Earth. Our
surprising conclusion was that “Although the Eötvös experiment has been
universally interpre... hiện toàn bộ
JETS and QCD: a historical review of the discovery of the quark and gluon jets and its impact on QCDSpringer Science and Business Media LLC - Tập 36 - Trang 245-326 - 2011
A. Ali, G. Kramer
The observation of quark and gluon jets has played a crucial role in
establishing Quantum Chromodynamics [QCD] as the theory of the strong
interactions within the Standard Model of particle physics. The jets, narrowly
collimated bundles of hadrons, reflect configurations of quarks and gluons at
short distances. Thus, by analysing energy and angular distributions of the jets
experimentally, the pro... hiện toàn bộ
Ryogo Kubo in his formative years as a physicistSpringer Science and Business Media LLC - Tập 45 - Trang 175-204 - 2020
Hiroto Kono
The Japanese theoretical physicist Ryogo Kubo made remarkable contributions to
statistical mechanics and condensed matter physics, amongst which his name is
most widely associated with the linear response theory. Despite his importance
in the history of modern physics, however, historians have paid him little
attention. Using his unpublished manuscripts in a newly organized archive, this
paper exa... hiện toàn bộ
Guglielmo Marconi, Augusto Righi and the invention of wireless telegraphySpringer Science and Business Media LLC - Tập 46 - Trang 1-28 - 2021
Matteo Leone, Nadia Robotti
One of the major accomplishments of the late nineteenth-century applied physics
was, as it is well known, the development of wireless telegraphy by Guglielmo
Marconi, future Nobel laureate. In this paper, we will explore what scientific
debt, if any, Marconi had toward another Italian physicist, internationally well
known for his research on electromagnetic waves: Augusto Righi. This question
