In the other two pronunciations of Latin, vowel sounds were not changed. The English pronunciation of Latin applied vowel sound changes which had occurred within English itself, where stressed vowels in a word became quite different from their unstressed counterpart. One immediate audible difference between the pronunciations is in the treatment of vowels. Meanwhile, scholarly proposals were made for a reconstructed Classical pronunciation, close to the pronunciation used in the late Roman Republic and early Empire, and with a more transparent relationship between spelling and pronunciation. Following Catholic emancipation in Britain in 1829 and the subsequent Oxford Movement, newly converted Catholics preferred the Italianate pronunciation, which became the norm for the Catholic liturgy. Until the beginning of the 19th century all English speakers used this pronunciation, including Roman Catholics for liturgical purposes. ![]() This traditional pronunciation then became closely linked to the pronunciation of English, and as the pronunciation of English changed with time, the English pronunciation of Latin changed as well. In the Middle Ages speakers of English, from Middle English onward, pronounced Latin not as the ancient Romans did, but in the way that had developed among speakers of French. The traditional English pronunciation of Latin, and Classical Greek words borrowed through Latin, is the way the Latin language was traditionally pronounced by speakers of English until the early 20th century.

But it's a natural consequence of the physics, if you apply the theory under these extreme conditions.This article or section should specify the language of its non-English content, using for phonetic transcriptions, with an appropriate ISO 639 code. "A photon suddenly converting from one flavor to another - you don't usually see this kind of thing. "You can think about the polarization as two flavors of photons," Lai continued. The polarity could therefore cause high-energy X-rays to swing 90 degrees relative to low-energy X-rays. ![]() Because they have a charge, however, these particles are influenced by the magnetar's powerful magnetic field. Lai said that in this phase, photons that have no electric charge could convert into a virtual pair of particles (an electron and a positron) that have equal and opposite charges but still combine to a net zero charge. QED predicts that as X-ray photons leave the tenuous atmosphere of a neutron star's surrounding plasma - hot and magnetized gas - the photons pass through a phase called vacuum resonance. This image uses data from the James Webb Space Telescope's Mid-Infrared Instrument (MIRI) to reveal the remnant in a new light.

"QED is one of the most successful physics theories, but it had not been tested in such strong magnetic field conditions." "In this observation of radiation from a faraway celestial object, we see a beautiful effect that is a manifestation of intricate, fundamental physics," Lai said. "Photon metamorphosis" is an element of quantum electrodynamics (QED), which is a field of physics examining subatomic interactions between electrons and photons. ![]() "Photon metamorphosis," meaning the transformation of X-ray photons into electrons and positrons, may be able to explain the weird behavior of X-rays around magnetars, Cornell University astrophysics professor Dong Lai said in a May 4 statement. Both energetic ray sets were oriented at 90 degrees to the electromagnetic field of the magnetar. IXPE information suggested that may be the case after looking at X-rays in the supernova remnant Cassiopeia A around the magnetar 4U 0142+61, located 13,000 light-years away.Īs the first-ever measurement of the polarization of X-rays around a magnetar, the IXPE observations showed that lower energy X-rays were polarized at 180 degrees to the high-energy X-rays. But, scientists were surprised in 2022 when data collected by NASA's Imaging X-ray Polarimetry Explorer (IXPE) satellite, which launched the year before, showed polarization may depend on energy. ![]()
