    This 1,000-Year-Old Smartphone Just Dialed In

    Lost & Found This 1,000-Year-Old Smartphone Just Dialed In By Franz Lidz and Clara VannucciFor 2,000 years, celestial observers mapped the heavens with astonishingly precise instruments called astrolabes.Resembling large, old-fashioned vest pocket watches, astrolabes allowed users to determine time, distances, heights, latitudes and even (with a horoscope) the future.Recently, an astrolabe dating to the 11th century turned up at the Fondazione Museo Miniscalchi-Erizzo in Verona, Italy.Federica Gigante, a historian at the University of Cambridge, first noticed it in a corner of a photograph while searching online for an image of a 17th-century collector whose miscellany was housed in the museum.After learning that the museum staff had very little information about the piece, Dr. Gigante went to Verona for a closer look.At the museum, a curator brought her to a side room, where she stood by a window and watched the sunlight illuminate the relic’s brass features.She made out Arabic inscriptions and, seemingly everywhere, faint Hebrew markings, Western numerals and scratches that looked like they had been keyed.“In the raking light, I realized that this wasn’t just an incredibly rare, ancient object but a powerful record of scientific exchange between Muslims, Jews and Christians over nearly a millennium,” Dr. Gigante said.Astrolabes are believed to have been around at the time of Apollonius of Perga, a Greek mathematician from the third-century B.C. known as the Great Geometer.Islamic scholars improved the gadgets, and by the ninth century A.D. the Persians were using astrolabes to locate Mecca and ascertain the five periods of prayer required each day, as stated in the Quran.The tool reached Europe through the Moorish conquest of much of Spain.By analyzing the Verona astrolabe’s design, construction and calligraphy, Dr. Gigante narrowed its provenance to 11th century Andalusia, where Muslims, Jews and Christians had worked alongside one another, particularly in the pursuit of science.“As the astrolabe changed hands, it underwent numerous modifications, additions and adaptations,” Dr. Gigante said.The original Arabic names of the signs of the zodiac were translated into Hebrew, a detail that suggested that the relic had at one point circulated within a Sephardi Jewish community.One side of a plate was engraved in Arabic with the phrase “for the latitude of Cordoba, 38° 30’”; on the other side “for the latitude of Toledo, 40°.”A handful of latitude values were corrected, some multiple times. Another plate was etched with North African latitudes which indicated that, during the instrument’s travels, it might have been used in Morocco or Egypt.A series of Hebrew additions led Dr. Gigante to conclude that the astrolabe had eventually reached the Jewish diaspora in Italy, where Hebrew, rather than Arabic, was used.“Basically, carving in the revisions was like adding apps to your smartphone,” Dr. Gigante said.Lost & FoundThis 1,000-Year-Old Smartphone Just Dialed InFranz Lidz and March 12, 2024Updated 10:06 a.m. ETProduced by More

    Americans Are Signing Up for Obamacare in Record Numbers

    The NewsMore than 15 million people have signed up for health insurance plans offered on the Affordable Care Act’s federal marketplace, a 33 percent increase compared to the same time last year, according to preliminary data released by the Biden administration on Wednesday.Federal health officials project that more than 19 million people will enroll in 2024 coverage by the end of the current enrollment period next month. That total would include those who gain coverage through state marketplaces, continuing the record-setting pace.“It means more Americans have the peace of mind of knowing that going to the doctor won’t empty their bank account,” Xavier Becerra, the health and human services secretary, said in a statement.An Affordable Care Act sign-up kiosk in a mall in Miami this month.Rebecca Blackwell/Associated PressWhy It Matters: The Affordable Care Act is expanding its reach.Despite a recent warning from former President Donald J. Trump, the front-runner in the race for the 2024 Republican presidential nomination, that he was “seriously looking at alternatives” to the Affordable Care Act, the latest surge in marketplace enrollment is a testament to the law’s enduring power.Legislation passed earlier in the Covid-19 pandemic increased federal subsidies for people buying plans, lowering the costs for many Americans. The Biden administration also lengthened the sign-up period and increased advertising for the program and funding for so-called navigators who help people enroll.“More and more people are realizing they can come onto the marketplace,” said Cynthia Cox, the director of the Program on the Affordable Care Act at KFF, a nonprofit health policy research group.She added: “Just because the A.C.A. has been around for a while doesn’t mean people who need to sign up for it know how to do that.”One Eye-Popping Statistic: 750,000 sign-ups in a single day.On Dec. 15 — the deadline to sign up for coverage that begins on Jan. 1 — nearly 750,000 people opted for a marketplace plan on HealthCare.gov. It was the largest single-day total yet.Dr. Benjamin Sommers, a health economist at Harvard who served in the Biden administration, said that improved outreach helped explain the record sign-ups. “I’m pleasantly surprised,” he said.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Russian Academics Aim to Punish Colleagues Who Backed Ukraine Invasion

    A campaign is circulating a list of dozens of researchers in the hopes they will be denied the prestige of election into the Russian Academy of Sciences.Some academic researchers in Russia are quietly working to prevent colleagues who have supported their country’s invasion of Ukraine from being elected to the Russian Academy of Sciences this month.If they succeed, they will deny those who back the war a prized credential that confers prestige in Russian institutions of higher learning. Their campaign could also show that some acts of protest remain possible despite a government crackdown on dissent.The Russian Academy of Sciences is a nonprofit network of research institutes in a variety of disciplines across the Russian Federation. It has just under 1,900 members in Russia and nearly 450 nonvoting foreign members.The academy elects new members every three years. The upcoming poll, starting on Monday, is for 309 seats, including 92 for senior academicians and 217 for corresponding members. The competition is steep: More than 1,700 candidates have applied.This month, a group of Russian researchers started circulating a list of dozens of candidates who have publicly supported Russia’s invasion of Ukraine by signing pro-war declarations or letters their universities or institutions released or by making such statements themselves.Hundreds of high-ranking officials at Russian universities, most of whom were administrators rather than prominent scientists, also signed a letter in support of the war in March.But many academic researchers have taken an antiwar stance. More than 8,000 Russian scientists and science journalists have signed an open letter opposing the invasion since it was first published in February.Three academic researchers — who were not identified because they risk job loss, imprisonment and their safety by publicly opposing the war — said in interviews that they helped create the list of those who supported the war to prevent them from being elected to the academy.Members of the leadership of the Russian Academy of Sciences did not respond to a request for comment.Some voters think the list could make a difference in the elections.“Most of the scientific community is definitely antiwar,” said Alexander Nozik, a physicist at the Moscow Institute of Physics and Technology who was not involved in creating the list. “Being in such a list could significantly reduce chances to be elected.”Some outside observers say that the Russian Academy is not as powerful as it once was.“It used to be a vast network of research institutes containing the best scientists in the country,” said Loren Graham, a historian who specializes in Russian science, with emeritus positions at the Massachusetts Institute of Technology and Harvard University. “Those institutes have now been stripped away by the Putin government, given to the Ministry of Education, and leaving the academy as an honorific society without genuine heft in science.”Members of the academy have also been implicated in ethical shortcomings in recent years. In 2020, a commission the body appointed found that Russian academic journals and research publications were riddled with plagiarism, self-plagiarism and gift authorship, where scientists were listed as co-authors of manuscripts without contributing to the work. As a result of the report, Russian journals retracted more than 800 research papers in which the authors were thought to have committed ethical violations.A separate 2020 exposé by the same commission at the academy found that several rectors and other senior university officials were guilty of publishing papers in questionable journals, listing fake collaborators and plagiarism.And some say such problems diminish the importance of the academy’s upcoming election.“A lot of people in Russian science still believe that the academy is the oldest structure that can do something — not because it is good but because others are worse,” said Dr. Nozik.Russia-Ukraine War: Key DevelopmentsCard 1 of 4In eastern Ukraine.
