Is the U.S. an empire?
Author, peace-keeper, refugee worker, human rights activist and now political candidate for the Indian Parliament, Shashi Tharoor straddles several worlds of experience.
Chairman of Dubai-based Afras Ventures and former Under-Secretary-General of the United Nations, Dr. Shashi Tharoor was the official candidate of India for the succession to UN Secretary-General Kofi Annan in 2006, and came a close second out of seven contenders in the race. His career began in 1978, when he joined the staff of the United Nations High Commissioner for Refugees (UNHCR) in Geneva, and included key responsibilities in peace-keeping after the Cold War and as a senior adviser to the Secretary-General, as well as the United Nations Under-Secretary-General for Communications and Public Information.
Dr. Tharoor is also the award-winning author of nine books, as well as hundreds of articles, op-eds and book reviews in a wide range of publications, including the New York Times, the Washington Post, the Los Angeles Times, the International Herald Tribune, Time, Newsweek and The Times of India. He has served for two years as a Contributing Editor and occasional columnist for Newsweek International. Since April 2001 he has authored a fortnightly column in The Hindu and since January 2007 in The Times of India.
Born in London in 1956, Dr. Tharoor was educated in India and the United States, completing a Ph. D. in 1978 at the Fletcher School of Law and Diplomacy at Tufts University, where he received the Robert B. Stewart Prize for Best Student. At Fletcher, Shashi Tharoor helped found and was the first Editor of the Fletcher Forum of International Affairs, a journal now in its 31st year. A compelling and effective speaker, he is fluent in English and French.
In January 1998, Dr. Tharoor was named a "Global Leader of Tomorrow" by the World Economic Forum in Davos, Switzerland. He is the recipient of several awards, including a Commonwealth Writers’ Prize, and was named to India’s highest honour for Overseas Indians, the Pravasi Bharatiya Samman, in 2004. He serves on the Board of Overseers of the Fletcher School of Law and Diplomacy, the board of trustees of the Aspen Institute India, and the Advisory Boards of the World Policy Journal, the Virtue Foundation and the human rights organization Breakthrough. He is also a Fellow of the New York Institute of the Humanities.
Question: Does America's status as the sole superpower mean it is becoming an empire?
Shashi Tharoor: No, I don’t think so. I think the U.S. has an extraordinary reach that no other country has; but empires actually go and conquer lands and rule them directly, and the U.S. has shown no particular taste for that. And the one place where it’s tried to do something analogous, Iraq, I think it’s learned bitterly the wisdom of the old French maxim of the statesman Talleyrand that the one thing you cannot do with a bear net is to sit on it. Just ruling a place by force is not going to be a way to build an empire. And I don’t see the U.S. becoming an empire.

Tharoor believes the US does not have a particular taste for empire.
The Spilhaus Projection may be more than 75 years old, but it has never been more relevant than today.
- Athelstan Spilhaus designed an oceanic thermometer to fight the Nazis, and the weather balloon that got mistaken for a UFO in Roswell.
- In 1942, he produced a world map with a unique perspective, presenting the world's oceans as one body of water.
- The Spilhaus Projection could be just what the oceans need to get the attention their problems deserve.
It's just the current cycle that involves opiates, but methamphetamine, cocaine, and others have caused the trajectory of overdoses to head the same direction
- It appears that overdoses are increasing exponentially, no matter the drug itself
- If the study bears out, it means that even reducing opiates will not slow the trajectory.
- The causes of these trends remain obscure, but near the end of the write-up about the study, a hint might be apparent
Through computationally intensive computer simulations, researchers have discovered that "nuclear pasta," found in the crusts of neutron stars, is the strongest material in the universe.
- The strongest material in the universe may be the whimsically named "nuclear pasta."
- You can find this substance in the crust of neutron stars.
- This amazing material is super-dense, and is 10 billion times harder to break than steel.
Superman is known as the "Man of Steel" for his strength and indestructibility. But the discovery of a new material that's 10 billion times harder to break than steel begs the question—is it time for a new superhero known as "Nuclear Pasta"? That's the name of the substance that a team of researchers thinks is the strongest known material in the universe.
Unlike humans, when stars reach a certain age, they do not just wither and die, but they explode, collapsing into a mass of neurons. The resulting space entity, known as a neutron star, is incredibly dense. So much so that previous research showed that the surface of a such a star would feature amazingly strong material. The new research, which involved the largest-ever computer simulations of a neutron star's crust, proposes that "nuclear pasta," the material just under the surface, is actually stronger.
The competition between forces from protons and neutrons inside a neutron star create super-dense shapes that look like long cylinders or flat planes, referred to as "spaghetti" and "lasagna," respectively. That's also where we get the overall name of nuclear pasta.

The researchers' computer simulations needed 2 million hours of processor time before completion, which would be, according to a press release from McGill University, "the equivalent of 250 years on a laptop with a single good GPU." Fortunately, the researchers had access to a supercomputer, although it still took a couple of years. The scientists' simulations consisted of stretching and deforming the nuclear pasta to see how it behaved and what it would take to break it.
While they were able to discover just how strong nuclear pasta seems to be, no one is holding their breath that we'll be sending out missions to mine this substance any time soon. Instead, the discovery has other significant applications.
One of the study's co-authors, Matthew Caplan, a postdoctoral research fellow at McGill University, said the neutron stars would be "a hundred trillion times denser than anything on earth." Understanding what's inside them would be valuable for astronomers because now only the outer layer of such starts can be observed.
"A lot of interesting physics is going on here under extreme conditions and so understanding the physical properties of a neutron star is a way for scientists to test their theories and models," Caplan added. "With this result, many problems need to be revisited. How large a mountain can you build on a neutron star before the crust breaks and it collapses? What will it look like? And most importantly, how can astronomers observe it?"
Another possibility worth studying is that, due to its instability, nuclear pasta might generate gravitational waves. It may be possible to observe them at some point here on Earth by utilizing very sensitive equipment.
The team of scientists also included A. S. Schneider from California Institute of Technology and C. J. Horowitz from Indiana University.
