History Readings

One thing that has hampered progress is that physicists still do not agree on how much the new particle weighs.

What does it matter how much a Higgs boson weighs? It could determine the fate of the universe.

his colleagues ran the numbers and concluded that the universe was in a precarious condition and could be prone to collapse in the far, far future. The reason lies in the Higgs field, the medium of which the Higgs boson is the messenger and which determines the structure of empty space, i.e., the vacuum.

It works like this. The Higgs field, like everything else in nature, is lazy, and, like water running downhill, always seeks to be in the state of lowest energy. Physicists assume that the Higgs field today is in the lowest state possible, but Dr. Giudice found that was not the case. What counts as rock bottom in today’s universe could turn out to be just a plateau. Our universe is like a rock perched precariously on a mountaintop, he explained, in what physicists call a metastable state. The Higgs field could drop to a lower value by a process known as quantum tunneling, although it is not imminent.

If that should happen — tomorrow or billions of years from now — a bubble would sweep out through the universe at the speed of light, obliterating the laws of nature as we know them.

The calculations assume that the Standard Model is the final word in physics, good for all times and places and energies — something that no physicist really believes. Theories like supersymmetry or string theory could intercede at higher energies and change the outcome.

The calculations also depend crucially on the mass of the top quark, the heaviest known elementary particle, as well as the Higgs, neither of which have been weighed precisely enough yet to determine the fate of the universe. If the top quark were just a little lighter or the Higgs a little heavier, 130 billion electron volts, Dr. Giudice said, the vacuum would in fact be stable.

, “Why do we happen to live at the edge of collapse?” He went on, “In my view, the message about near-criticality of the universe is the most important thing we have learned from the discovery of the Higgs boson so far.” Guido Tonelli of CERN and the University of Pisa, said, “If true, it is somehow magic.” We wouldn’t be having this discussion, he said, if there hadn’t been enough time already for this universe to produce galaxies, stars, planets and “human beings who are attempting to produce a vision of the world,” he said.

“So, in some sense, we are here, because we have been lucky, because for this particular universe the lottery produced a certain set of numbers, which allow the universe to have an evolution, which is very long.”

the David S. Wyman Institute for Holocaust Studies, a research organization in Washington, has circulated a detailed rebuttal, as well as a rival book, “FDR and the Holocaust: A Breach of Faith,” zeroing in on what it characterizes as Roosevelt’s personal desire to limit Jewish immigration to the United States.

They pointed in particular to the fate of the 937 German Jewish refugees on the ocean liner St. Louis, who were turned away from Cuba in May 1939 and sent back to other European countries, where 254 died after war broke out. The episode, made famous in the 1974 novel “Voyage of the Damned” and a subsequent film, has come to seem emblematic of American callousness. There is simply no evidence, Mr. Breitman and Mr. Lichtman say, to support accounts that the United States Coast Guard was ordered to prevent the refugees from coming ashore in Florida. What’s more, they were turned away from Cuba, the authors argue, as part of a backlash against a previous influx of some 5,000 refugees to that country, who may have been admitted under the terms of a previously unknown deal between Roosevelt and the Cuban leader Fulgencio Batista, who got reduced tariffs for his nation’s sugar in return. The book notes that the St. Louis affair unfolded against a backdrop of intense isolationist and anti-immigrant sentiment in the United States while Roosevelt was preparing to press Congress to allow the sale of weapons to nations victimized by German aggression.

The idea that the Allies could and should have bombed the crematories or the rail lines leading to them came to wide public attention with a 1978 article in Commentary by Mr. Wyman, who reprised it in a best-selling book, “The Abandonment of the Jews,” which became the basis for the 1994 PBS documentary “America and the Holocaust: Many people, the authors say, believe that Roosevelt refused to bomb the camp (an option, historians note, that became feasible only in May 1944, after 90 percent of Jewish victims of the Holocaust were already dead). But the book contends that there is no evidence that any such proposal came to him, though a number of Jewish leaders did meet with lower-level officials to plead for bombing. And while the authors call the objections raised by those officials “specious,” they maintain (echoing others) that bombing would not have significantly impeded the killing.

the book points to the War Refugee Board, established by Roosevelt in 1944, which they say may have helped save about 200,000 Jews — a number that, if even 50 percent accurate, they write, “compares well” with the number that might have been saved by bombing Auschwitz.

In “A Breach of Faith” Mr. Medoff argues that Jewish immigration levels in the 1930s were largely below established quotas because of Roosevelt’s animus, not as a result of anti-immigrant and anti-Semitic sentiment in Congress and the State Department. Roosevelt’s vision for America was “based on the idea of having only a small number of Jews,” Mr. Medoff said in an interview. Mr. Breitman and Mr. Lichtman’s book, he added, is just an effort “to rescue Roosevelt’s image from the overwhelming evidence that he did not want to rescue the Jews.”

Mr. Breitman and Mr. Lichtman scoffed at that charge, noting that their book is certainly not always flattering to Roosevelt. They depict him as missing many opportunities to aid Jews and generally refusing to speak specifically in public about Hitler’s Jewish victims, lest he be accused of fighting a “Jewish war.” “This is not an effort to write a pro-Roosevelt book,” Mr. Breitman said. “It’s merely pro-Roosevelt in comparison to some things that are out there.”

In the end, however, their verdict is favorable, crediting Roosevelt’s policies with helping to save hundreds of thousands of Jews, as well as preventing a German conquest of Egypt that would have doomed any future Jewish state. “Without F.D.R.’s policies and leadership,” they write, “there may well have been no Jewish communities left in Palestine, no Jewish state, no Israel.”

Henry L. Feingold, the author of “The Politics of Rescue: The Roosevelt Administration and the Holocaust, 1938-1945,” bemoaned the rise of “accusatory” history that elevates retrospective “what ifs” over historical context. Roosevelt, he said, had one overriding concern: to win the war. “The survivors said, ‘You didn’t do enough to save us,’ and who could deny it?” Mr. Feingold said. “But do you write history as it should have been or as it was?”

It is doubtful that China will reinforce the United Nations sanctions by imposing penalties of its own

American troops stationed in South Korea could move north and help unite the Korean Peninsula under an American umbrella, the last thing China would want,

Before this study, continuous temperature record reconstruction only went back about 2,000 years. The temperature trend produces a line shaped like a "hockey stick" with a sudden spike after what had been a fairly steady line. That data came from tree rings, ice cores and lake sediments.

the general downward trend of temperatures that reversed 100 years ago seemed to indicate the Earth was heading either toward another ice age or little ice age from about 1550 to 1850. Or it was continuing to cool naturally until greenhouse gases from the burning of fossil fuels changed everything.

"We have, through human emissions of carbon dioxide and other heat-trapping gases, indefinitely delayed the onset of the next ice age and are now heading into an unknown future where humans control the thermostat of the planet,

The laws are gradually internalized through a system of lifelong study, argument and practice. The external laws may seem, at first, like an imposition, but then they become welcome and finally seem like a person’s natural way of being.

At first piano practice seems like drudgery, like self-limitation, but mastering the technique gives you the freedom to play well and create new songs. Life is less a journey than it is mastering a discipline or craft.

there are still obligations that precede choice. For example, a young person in mainstream America can choose to marry or not. In Orthodox society, young adults have an obligation to marry and perpetuate the covenant and it is a source of deep sadness when they cannot.

“Marriage is about love, but it is not first and foremost about love,” Soloveichik says. “First and foremost, marriage is about continuity and transmission.”

“The technology to allow the resale of digital goods is now in place, and it will cause a dramatic upheaval,

“The vast majority of e-books are not available in your public library,” said Brandon Butler, director of public policy initiatives for the Association of Research Libraries. “That’s pathetic.”

For over a century, the ability of consumers, secondhand bookstores and libraries to do whatever they wanted with a physical book has been enshrined in law. The crucial 1908 case involved a publisher that issued a novel with a warning that no one was allowed to sell it for less than $1. When Macy’s offered the book for 89 cents, the publisher sued. That led to a landmark Supreme Court ruling limiting the copyright owner’s control to the first sale. After that, it was a free market.

I am trying to imagine a white president forced to show his papers at a national news conference, and coming up blank. I am trying to a imagine a prominent white Harvard professor arrested for breaking into his own home, and coming up with nothing. I am trying to see Sean Penn or Nicolas Cage being frisked at an upscale deli, and I find myself laughing in the dark. It is worth considering the messaging here. It says to black kids: “Don’t leave home. They don’t want you around.” It is messaging propagated by moral people.

Everything is linked: Chinese drought and Russian bushfires produced wheat shortages leading to higher bread prices fueling protests in Tahrir Square. Sternberg calls it the globalization of “hazard.”

from 2006 to 2011, up to 60 percent of Syria’s land experienced the worst drought ever recorded there — at a time when Syria’s population was exploding and its corrupt and inefficient regime was proving incapable of managing the stress.

The future does not look much brighter. “On a scale of wetness conditions,” Femia and Werrell note, “ ‘where a reading of -4 or below is considered extreme drought,’ a 2010 report by the National Center for Atmospheric Research shows that Syria and its neighbors face projected readings of -8 to -15 as a result of climatic changes in the next 25 years.

Similar trends, they note, are true for Libya, whose “primary source of water is a finite cache of fossilized groundwater, which already has been severely stressed while coastal aquifers have been progressively invaded by seawater.”

when it comes to climate change, we need to manage what is unavoidable and avoid what is unmanageable. That requires collective action globally to mitigate as much climate change as we can and the building of resilient states locally to adapt to what we can’t mitigate.

The Arab world is doing the opposite. Arab states as a group are the biggest lobbyists against efforts to reduce oil and fuel subsidies. According to the International Monetary Fund, as much as one-fifth of some Arab state budgets go to subsidizing gasoline and cooking fuel — more than $200 billion a year in the Arab world as a whole — rather than into spending on health and education. Meanwhile, locally, Arab states are being made less resilient by the tribalism and sectarianism that are eating away at their democratic revolutions.

The United States, which fought on South Korea’s side during the war, still keeps 28,500 troops in South Korea.

During a strike in 2008 in Oaxaca, I remember walking through the temporary campground in search of a teacher reading a book. Among tens of thousands, I found not one

I shouldn’t have been surprised by the response when I spoke at a recent event for promoting reading for an audience of 300 or so 14- and 15-year-olds. “Who likes to read?” I asked. Only one hand went up in the auditorium. I picked out five of the ignorant majority and asked them to tell me why they didn’t like reading. The result was predictable: they stuttered, grumbled, grew impatient. None was able to articulate a sentence, express an idea.

A few years back, I spoke with the education secretary of my home state, Nuevo León, about reading in schools. He looked at me, not understanding what I wanted. “In school, children are taught to read,” he said. “Yes,” I replied, “but they don’t read.” I explained the difference between knowing how to read and actually reading, between deciphering street signs and accessing the literary canon.

We have turned schools into factories that churn out employees. With no intellectual challenges, students can advance from one level to the next as long as they attend class and surrender to their teachers. In this light it is natural that in secondary school we are training chauffeurs, waiters and dishwashers.

The educational machine does not need fine-tuning; it needs a complete change of direction. It needs to make students read, read and read.

police have yet to identify him. The mystery man slipped away into the darkness while police arrested the suspected criminal, who was later charged with fraud-related offenses and handling stolen goods.

The numbers astound: 30,000 slave labor camps; 1,150 Jewish ghettos; 980 concentration camps; 1,000 prisoner-of-war camps; 500 brothels filled with sex slaves; and thousands of other camps used for euthanizing the elderly and infirm, performing forced abortions, “Germanizing” prisoners or transporting victims to killing centers.

In Berlin alone, researchers have documented some 3,000 camps and so-called Jew houses, while Hamburg held 1,300 sites.

Dr. Dean, a co-researcher, said the findings left no doubt in his mind that many German citizens, despite the frequent claims of ignorance after the war, must have known about the widespread existence of the Nazi camps at the time.

Even at the current concentration, the evidence suggests that increases in sea level of 25 feet or more may have already become inevitable, albeit over a long period.
