Welcome to the Universe microsite receives a Webby

We’re pleased to announce that the accompanying microsite to Welcome to the Universe by Neil DeGrasse Tyson, Michael A. Strauss, and J. Richard Gott has won a People’s Choice Webby in the Best Use of Animation or Motion Graphics category. Congratulations to Eastern Standard, the web designer, on a beautifully designed site.

Winning a Webby is especially gratifying because it honors how much fun we had making the site. We knew we wanted an unconventional approach that would mirror both the complexity and accessibility of the book it was meant to promote. Our wonderful in-house team and creative partners, Eastern Standard took on this challenge, and we are so happy with the results.
—Maria Lindenfeldar, Creative Director, Princeton University Press 

Creating this microsite was a wonderful experiment for us at Princeton University Press.  We wanted to explore how we, as a publisher, could present one of our major books to the public in a compelling way in the digital environment.  Ideally, we had a vision of creating a simple site with intuitive navigation that would give readers an inviting mini-tour through the topics of the book, Welcome to the Universe, by Neil deGrasse Tyson, Michael Strauss, and Richard Gott.  The animation was meant to be subtle, but meaningful, and to gently encourage user interaction, so that the focus would always remain immersing the reader in the content of the book – what we feel is the most interesting part!  We were very happy with how it turned out and now all the more thrilled and honored that the site was chosen for a Webby!
—Ingrid Gnerlich, Science Publisher, Princeton University Press

Exclusive interview with Neil deGrasse Tyson, Michael A. Strauss, and J. Richard Gott on their NYT bestseller, Welcome to the Universe

UniverseWe’re thrilled to announce that Welcome to the Universe, a guided tour of the cosmos by three of today’s leading astrophysicists, recently made the New York Times extended bestseller list in science. Inspired by the enormously popular introductory astronomy course that Neil deGrasse Tyson, Michael A. Strauss, and J. Richard Gott taught together at Princeton, this book covers it all—from planets, stars, and galaxies to black holes, wormholes, and time travel. The authors introduce some of the hot topics in astrophysics in today’s Q&A:

What is the Cosmic Perspective?

NDT: A view bigger than your own that offers a humbling, yet enlightening, and occasionally empowering outlook on our place as humans in time, space, on Earth and in the Universe. We devote many pages of Welcome to the Universe to establishing our place in the cosmos – not only declarations of that place, but also the reasons and the foundations for how we have come to learn how we fit in that place. When armed with a cosmic perspective, many earthly problems seem small, yet you cultivate a new sense of belonging to the universe. You are, in fact, a participant in the great unfolding of cosmic events.

What are some of the takeaways from the book?

NDT: If you read the entire book, and if we have succeeded as authors, then you should walk away with a deep sense of the operations of nature, and an appreciation for the size and scale of the universe; how and why planets form; how and why we search for planets orbiting around other stars, and alien life that may thrive upon them; how and why stars are born, live out their lives and die; what galaxies are and why they are the largest organizations of stars in the universe; the large scale structure of galaxies and space-time; the origins and future of the universe, Einstein’s relativity, black holes, and gravitational waves; and time travel. If that’s not enough, you will also learn about some of the continued unsolved mysteries in our field, such as dark matter, dark energy, and multiverses.

This book has more equations than do most popular books about astrophysics.  Was that a deliberate decision?

MAS: Yes.  The book’s subtitle is “An Astrophysical Tour,” and one of our goals in writing it was to show how observations, the laws of physics, and some high school mathematics can combine to yield the amazing discoveries of modern astrophysics: A Big Bang that happened 13.8 billion years ago (we show you how that number is determined), the dominant role dark matter has in the properties of galaxies (we tell you how we came to that conclusion), even the fact that some planets orbiting other stars have conditions conducive for liquid water to exist on their surface, thought to be a necessary prerequisite for life. Our goal is not just to present the wonders of the universe to the reader, but to have the reader understand how we have determined what we know, and where the remaining uncertainties (and there are plenty of them!) lie.

So your emphasis is on astrophysics as a quantitative science, a branch of physics?

MAS:  Yes.  We introduce the necessary physics concepts as we go: we do not expect the reader to know this physics before they read the book.  But astrophysicists are famous (perhaps notorious!) for rough calculations, “to astrophysical accuracy.”  We also lead the reader through some examples of such rough calculations, where we aim to get an answer to “an order of magnitude.”  That is, we’re delighted if we get an estimate that’s correct to within a factor of 2, or so.  Such calculations are useful in everyday life, helping us discriminate the nonsensical from the factual in the numerical world in which we live.

Can you give an example?

MAS: Most people in everyday discourse don’t think much about the distinction between “million,” “billion,” “trillion,” and so on, hearing them all as “a really big number,” with not much difference between them.  It is actually a real problem, and the difference between Federal budget items causing millions vs. billions of dollars is of course huge.  Our politicians and the media are confusing these all the time.  We hope that the readers of this book will come away with a renewed sense of how to think about numbers, big and small, and see whether the numbers they read about in the media make sense.

Is time travel possible?

JRG: In 1905 Einstein proved that time travel to the future is possible. Get on a rocket and travel out to the star Betelgeuse 500 light-years away and return at a speed of 99.995 % the speed of light and you will age only 10 years, but when you get back it will be the year 3016 on Earth. Even though we have not gone that fast or far, we still have time travelers among us today. Our greatest time traveler to date is the Russian cosmonaut Gennady Padalka, who by virtue of traveling at high speed in low Earth orbit for 879 days aged 1/44 of a second less than if he had stayed home. Thus, when he returned, he found Earth to be 1/44 of a second to the future of where he expected it to be. He has time traveled 1/44 of a second to the future. An astronaut traveling to the planet Mercury, living there for 30 years, and returning to Earth, would time travel into the future by 22 seconds. Einstein’s equations of general relativity, his theory of curved spacetime to explain gravity, have solutions that are sufficiently twisted to allow time travel to the past. Wormholes and moving cosmic strings are two examples. The time traveler can loop back to visit an event in his own past. Such a time machine cannot be used to journey back in time before it was created. Thus, if some supercivilization were to create one by twisting spacetime in the year 3000, they might use it to go from 3002 back to 3001, but they couldn’t use it go back to 2016, because that is before the time loop was created. To understand whether such time machines can be realized, we may need to understand how gravity works on microscopic scales, which will require us to develop a theory of quantum gravity. Places to look for naturally occurring time machines would be in the interiors of rotating black holes and at the very beginning of the universe, where spacetime is strongly curved.

Do we live in a multiverse?

JRG: A multiverse seems to be a natural consequence of the theory of inflation. Inflation explains beautifully the pattern of slightly hotter and colder spots we see in the Cosmic Microwave Background Radiation. It explains why the universe is so large and why it is as smooth as it is and still has enough variations in density to allow gravity to grow these into galaxies and clusters of galaxies by the present epoch. It also explains why the geometry of the universe at the present epoch is approximately Euclidean. Inflation is a period of hyperactive accelerated expansion occurring at the beginning of our universe. It is powered by a large vacuum energy density and negative pressure permeating empty space that is gravitationally repulsive. The universe doubles in size about every 3 10-38 seconds. With this rate of doubling, it very quickly grows to enormous size: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024… That explains why the universe is so large. When the high density vacuum state decays, it doesn’t do so all at once. Like water boiling in a pot, it does not turn into steam all at once, but should form bubbles. Each expanding bubble makes a universe. The inflationary sea should expand forever, creating an infinite number of bubble universes, ours being one of them. Other distant bubble universes are so far away, and the space between us and them is expanding so fast, that light from them may never reach us. Nevertheless, multiple universes seem a nearly inevitable consequence of inflation.

What discovery about the universe surprises or inspires you the most?

JRG: Perhaps the most amazing thing about the universe is that it is comprehensible to intelligent, carbon-based life forms like ourselves. We have been able to discover how old the universe is (13.8 billion years) and figure out many of the laws by which it operates. The object of this book is to make the universe comprehensible to our readers.

Don’t miss this C-Span video on the book, in which the authors answer questions about the universe, including how it began and the likelihood of intelligent life elsewhere.

#ThanksEinstein: Katherine Freese on how relativity rejuvenated her career

Thanks Einstein Meme 3Under the Spell of Relativity

By Katherine Freese

Katherine Freese is director of Nordita, the Nordic Institute for Theoretical Physics, in Stockholm, and author of The Cosmic Cocktail, which tells of the epic quest to solve one of the most compelling enigmas of modern science—what is the universe made of? This is the story of how one of today’s foremost pioneers in the study of dark matter came back from the brink of burnout because of Relativity.

My career choice was hugely influenced by the work of Albert Einstein. I chose a career in physics precisely because I was inspired by his theories of relativity. My first exposure to physics was at Exeter Summer School in New Hampshire when I was fifteen years old. I went there after my junior year in high school because, frankly, I enjoyed learning and would otherwise have been bored over the long summer. I took an introductory course in physics and have to admit that, at first, I was a bit intimidated. But I got into it quickly and was gratified to discover that I did really well. The course was inspiring, and my teacher Mr. Dudley probably has no idea what an impact he had on me.

It was when the summer course turned to Special Relativity that I became really excited. What a bizarre and fascinating subject! To begin with, the idea that there is no absolute reference frame was an eye-opener. I later tried to explain this to friends, but they persisted in arguing that the Earth really does provide a special reference frame, world freeseat least for humans, so we should just compute everything from our own point of view.

Strange paradoxes arise when one makes one simple postulate, that the speed of light is the same in every reference frame. Two observers moving with relativistic speeds (relative to one another) measure completely different things. Clocks measure different times, and rulers measure different lengths. The shortest time is measured in the reference frame where the event takes place, and in every other frame time appears dilated. So an astronaut, who goes off into space and eventually returns, ages more slowly than the rest of us. There can be time travel! In the sense that the astronaut can come back to the Earth at an arbitrarily distant point in the future…if she can tolerate traveling at those speeds. Recently I met quite a few astronauts in Stockholm at the Congress of the Association of Space Explorers. They are amazing people. I was invited to give a 20 minute talk on “What we know about the Universe today.” A tall order in front of these folks. Can you guess what I talked about? Cosmology, beginning with Einstein’s relativity, of course.

These exciting things I learned when I was 15 made me determined to learn more physics, and I ended up majoring in physics in college. I went very young, at 16, and graduated with a bachelor’s degree in physics from Princeton University at the age of 20. It was really hard, I was burning out quickly, and at that point I wasn’t sure I wanted to continue. Chapter One of The Cosmic Cocktail, the book that was published by Princeton University Press just over a year ago, describes what happened next. I decided to take some time off from school. With my best friend, I went off to Tokyo to teach English and ended up serving drinks in bars for a giant salary. (I finally surpassed it a few years ago as a Full Professor.) A year and a half later, I went to Korea to renew my visa. While I was traveling around Pusang, my stomach, or so I thought, started to hurt. When I returned to Tokyo I was walking around doubled over with pain. Indeed it turned out to be appendicitis. I went to the Catholic Hospital, run by English nuns, and had my appendix removed.

While I was lying in the hospital bed, I read the only book I had brought with me, Spacetime Physics by Taylor and Wheeler. It is a book about Einstein’s special relativity. The book is beautifully written and only requires simple knowledge of forces, energy, and so on, and I loved it. The minute I got out of the hospital, I flew back to the US, reinvigorated by the desire to study physics. I contacted Columbia University, which had previously accepted me, and they let me in at a moment’s notice. I was lucky they did.

Einstein’s influence persisted. Two years into my graduate program at Columbia University, I went to Fermilab, the particle physics accelerator outside of Chicago, to work in experimental high energy physics. However, I also took a class in cosmology at the University of Chicago twice a week, out of curiosity. Plus, it took me into the city of Chicago. Fermilab is on a farm an hour west and has buffalo roaming around. The professor who taught the course, David Schramm, was a giant both physically and mentally, and one of the founders of the field of astroparticle physics, where the smallest particles explain the properties of the largest galaxies. We nicknamed him “Schrammbo.” (If you want to know more about him, you’ll have to read my book.) In that course, Einstein’s equations were applied to the Universe as a whole. Wow. I stopped showing up in the lab and instead sat in my housing at Fermilab and read about general relativity, this time at a graduate level framed by far deeper mathematics. Again, it was a turning point. I transferred to the University of Chicago to get my PhD with David Schramm in the field of cosmology.

In human history, every culture has had creation myths. In the past 100 years we have developed our own, the Big Bang. The difference is that the Hot Big Bang is right! The achievements over the past century in the field of cosmology are breakthroughs for all of mankind. We understand everything about our observable Universe all the way out to the farthest distant that light could have traveled to us in the age of the Universe (anything farther out could not have impacted us because the information could not travel in excess of the speed of light).

Now I’m a professional. I work with Einstein’s equations or their immediate consequences every day. I’m a theorist. I invent things and hope they turn out to match reality. All my work lies within the framework of modern cosmology, which began with Einstein’s work in relativity in 1915. What a brilliant man he was! Ever since I learned about relativity I’ve been under its spell, and I still am.

Katherine Freese is director of Nordita, the Nordic Institute for Theoretical Physics, in Stockholm, and professor of physics at the University of Michigan. She is the author of The Cosmic Cocktail.

Princeton University Press launches The Digital Einstein Papers

DEP front page

Launching today, THE DIGITAL EINSTEIN PAPERS is a publicly available website of the collected and translated papers of Albert Einstein that allows readers to explore the writings of the world’s most famous scientist as never before.

Princeton, NJ – December 5, 2014 – Princeton University Press, in partnership with Tizra, Hebrew University of Jerusalem, and California Institute of Technology, announces the launch of THE DIGITAL EINSTEIN PAPERS (http://einsteinpapers.press.princeton.edu). This unique, authoritative resource provides full public access to the translated and annotated writings of the most influential scientist of the twentieth century: Albert Einstein.

“Princeton University Press has a long history of publishing books by and about Albert Einstein, including the incredible work found in The Collected Papers of Albert Einstein,” said Peter Dougherty, director of Princeton University Press. “We are delighted to make these texts openly available to a global audience of researchers, scientists, historians, and students keen to learn more about Albert Einstein. This project not only furthers the mission of the press to publish works that contribute to discussions that have the power to change our world, but also illustrates our commitment to pursuing excellence in all forms of publishing—print and digital.”

THE DIGITAL EINSTEIN PAPERS website presents the complete contents of The Collected Papers of Albert Einstein, and, upon its launch, the website—http://einsteinpapers.press.princeton.edu—will contain 5,000 documents covering the first forty-four years of Einstein’s life, up to and including the award of the Nobel Prize in Physics and his long voyage to the Far East. Additional material will be available on the website approximately eighteen months after the print publication of new volumes of The Collected Papers. Eventually, the website will provide access to all of Einstein’s writings and correspondence, accompanied by scholarly annotation and apparatus.

What sorts of gems will users discover in THE DIGITAL EINSTEIN PAPERS? According to Diana L. Kormos-Buchwald, director of the Einstein Papers Project, “This material has been carefully researched and annotated over the last twenty-five years and contains all of Einstein’s scientific and popular writings, drafts, lecture notes, and diaries, and his professional and personal correspondence up to his forty-fourth birthday—so users will discover major scientific articles on the general theory of relativity, gravitation, and quantum theory alongside his love letters to his first wife, correspondence with his children, and his intense exchanges with other notable scientists, philosophers, mathematicians, and political personalities of the early twentieth century.”

Buchwald also noted that THE DIGITAL EINSTEIN PAPERS will introduce current and future generations to important ideas and moments in history, saying, “It is exciting to think that thanks to the careful application of new technology, this work will now reach a much broader audience and stand as the authoritative digital source for Einstein’s written legacy.”

THE DIGITAL EINSTEIN PAPERS enables readers to experience the writings of Albert Einstein in unprecedented ways. Advance search technology improves discoverability by allowing users to perform keyword searches across volumes of Einstein’s writing and, with a single click, navigate between the original languages in which the texts were written and their English translations. Further exploration is encouraged by extensive explanatory footnotes, introductory essays, and links to the Einstein Archives Online, where there are thousands of high-quality digital images of Einstein’s writings.

The Tizra platform was selected for this project, according to Kenneth Reed, manager of digital production for Princeton University Press, because of its highly flexible, open, and intuitive content delivery approach, and its strong reputation for reliability. Equally important was creating a user-friendly reading experience.

“One of the reasons we chose Tizra is that we wanted to preserve the look and feel of the volumes,” said Reed. “You’ll see the pages as they appear in the print volumes, with added functionality such as linking between the documentary edition and translation, as well as linking to the Einstein Archives Online, and the ability to search across all the volumes in English and German.”

THE DIGITAL EINSTEIN PAPERS is an unprecedented scholarly collaboration that highlights what is possible when technology, important content, and a commitment to global scholarly communication are brought together. We hope you will join us in celebrating this achievement and invite you to explore Einstein’s writings with the links below.

Work on THE DIGITAL EINSTEIN PAPERS was supported by the Harold W. McGraw, Jr. endowment, the California Institute of Technology, the National Science Foundation, the National Endowment for the Humanities, and the Arcadia Fund, U.K.

A Sampling of Documents Found in THE DIGITAL EINSTEIN PAPERS

Website: http://einsteinpapers.press.princeton.edu

“My Projects for the Future” — In this high school French essay, a seventeen-year-old Einstein describes his future plans, writing that “young people especially like to contemplate bold projects.”

Letter to Mileva Marić — The first volume of The Collected Papers of Albert Einstein revealed that the young Einstein had fathered an illegitimate daughter. In this letter to his sweetheart and future wife, Einstein, age twenty-two, expresses his happiness at the birth of his daughter Lieserl, and asks about her health and feeding.

Einstein’s first job offer — Einstein graduated from university in 1900, but had great difficulty finding academic employment. He received this notice of his appointment as a technical clerk at the Swiss Patent Office in June 1902 and would later describe his time there as happy and productive.

“On the Electrodynamics of Moving Bodies” — Einstein’s 1905 paper on the special theory of relativity is a landmark in the development of modern physics.

“On a Heuristic Point of View Concerning the Production and Transformation of Light” — Einstein received the Nobel Prize in Physics for this paper on the hypothesis of energy quanta.

The telegram informing that Einstein he has won the Nobel Prize — Einstein was traveling in the Far East when he officially learned via telegram that he had been awarded the prize. However, he had long been expecting the prize, as evidenced by a clause regarding its disposition in a preliminary divorce agreement from Mileva in 1918.

“The Field Equations of Gravitation” — Einstein spent a decade developing the general theory of relativity and published this article in late 1915.

To his mother Pauline Einstein — Einstein writes to his ailing mother to share the happy news that his prediction of gravitational light bending was confirmed by a British eclipse expedition in 1919.

To Heinrich Zangger, on the mercurial nature of fame — Having been propelled to world fame, Einstein writes to his friend about the difficulties of being “worshipped today, scorned or even crucified tomorrow.”

To Max Planck, on receiving credible death threats — Einstein writes that he cannot attend the Scientist’s Convention in Berlin because he is “supposedly among the group of persons being targeted by nationalist assassins.”

Four Lectures on the Theory of Relativity, held at Princeton University in May 1921 — On his first trip to the United States, Einstein famously delivered these lectures on the theory of relativity.

About The Collected Papers of Albert Einstein
