Transport yourself to antiquity with full-color maps, drawings, photos, and 3D reconstructions of the Eternal City, featuring descriptions of the fourteen regions of Rome and the urban history of each in unprecedented detail. Included are profiles and reconstructions of more than 500 major monuments and works of art, such as the Sanctuary of Vesta, the domus Augusti, and the Mausoleum of Augustus. This two-volume, slipcased edition examines the city’s topography and political-administrative divisions, trade and economic production, and social landscape and infrastructure using the most current archaeological findings and the latest mapping technologies. Take a look at a sampling of some of the detailed images from the book here, and be sure to mark your calendar for when this book becomes available in February 2017.
Virus by Marilyn Roossinck is your go-to guide to the fascinating world of viruses. This stunningly illustrated reference work offers an unprecedented look at 101 microbes that infect all branches of life on Earth—from humans and other animals to insects, plants, fungi, and bacteria. Check out our new trailer for an introduction:
In the January/February 2000 issue of Computing in Science and Engineering, Jack Dongarra and Francis Sullivan chose the “10
algorithms with the greatest influence on the development and practice of science and engineering in the 20th century” and presented a group of articles on them that they had commissioned and edited. (A SIAM News article by Barry Cipra gives a summary for anyone who does not have access to the original articles). This top ten list has attracted a lot of interest.
Sixteen years later, I though it would be interesting to produce such a list in a different way and see how it compares with the original top ten. My unscientific—but well defined— way of doing so is to determine which algorithms have the most page locators in the index of The Princeton Companion to Applied Mathematics (PCAM). This is a flawed measure for several reasons. First, the book focuses on applied mathematics, so some algorithms included in the original list may be outside its scope, though the book takes a broad view of the subject and includes many articles about applications and about topics on the interface with other areas. Second, the content is selective and the book does not attempt to cover all of applied mathematics. Third, the number of page locators is not necessarily a good measure of importance. However, the index was prepared by a professional indexer, so it should reflect the content of the book fairly objectively.
A problem facing anyone who compiles such a list is to define what is meant by “algorithm”. Where does one draw the line between an algorithm and a technique? For a simple example, is putting a rational function in partial fraction form an algorithm? In compiling the following list I have erred on the side of inclusion. This top ten list is in decreasing order of the number of page locators.
- Newton and quasi-Newton methods
- Matrix factorizations (LU, Cholesky, QR)
- Singular value decomposition, QR and QZ algorithms
- Monte-Carlo methods
- Fast Fourier transform
- Krylov subspace methods (conjugate gradients, Lanczos, GMRES,
- Simplex algorithm
- Kalman filter
Note that JPEG (1992) and PageRank (1998) were youngsters in 2000, but all the other algorithms date back at least to the 1960s.
By comparison, the 2000 list is, in chronological order (no other ordering was given)
- Metropolis algorithm for Monte Carlo
- Simplex method for linear programming
- Krylov subspace iteration methods
- The decompositional approach to matrix computations
- The Fortran optimizing compiler
- QR algorithm for computing eigenvalues
- Quicksort algorithm for sorting
- Fast Fourier transform
- Integer relation detection
- Fast multipole method
The two lists agree in 7 of their entries. The differences are:
|PCAM list||2000 list|
|Newton and quasi-Newton methods||The Fortran Optimizing Compiler|
|Jpeg||Quicksort algorithm for sorting|
|PageRank||Integer relation detection|
|Kalman filter||Fast multipole method|
Of those in the right-hand column, Fortran is in the index of PCAM and would have made the list, but so would C, MATLAB, etc., and I draw the line at including languages and compilers; the fast multipole method nearly made the PCAM table; and quicksort and integer relation detection both have one page locator in the PCAM index.
There is a remarkable agreement between the two lists! Dongarra and Sullivan say they knew that “whatever we came up with in the end, it would be controversial”. Their top ten has certainly stimulated some debate, but I don’t think it has been too controversial. This comparison suggests that Dongarra and Sullivan did a pretty good job, and one that has stood the test of time well.
Finally, I point readers to a talk Who invented the great numerical algorithms? by Nick Trefethen for a historical perspective on algorithms, including most of those mentioned above.

From chapter 11 of Garden Insects of North America:
Most lady beetles lay between 5 and 30 orange-yellow eggs at a time. They are distinctive, but may sometimes resemble those of leaf beetles. Eggs are laid near colonies of insects to provide food for the larvae.
Garden Insects of North America is the most comprehensive and user-friendly guide to the common insects and mites affecting yard and garden plants in North America. In a manner no previous book has come close to achieving, through full-color photos and concise, clear, scientifically accurate text, it describes the vast majority of species associated with shade trees and shrubs, turfgrass, flowers and ornamental plants, vegetables, and fruits—1,420 of them, including crickets, katydids, fruit flies, mealybugs, moths, maggots, borers, aphids, ants, bees, and many, many more. For particularly abundant bugs adept at damaging garden plants, management tips are also included. Covering all of the continental United States and Canada, this is the definitive one-volume resource for amateur gardeners, insect lovers, and professional entomologists alike.
To ease identification, the book is organized by plant area affected (e.g., foliage, flowers, stems) and within that, by taxa. Close to a third of the species are primarily leaf chewers, with about the same number of sap suckers. Multiple photos of various life stages and typical plant symptoms are included for key species. The text, on the facing page, provides basic information on host plants, characteristic damage caused to plants, distribution, life history, habits, and, where necessary, how to keep “pests” in check–in short, the essentials to better understanding, appreciating, and tolerating these creatures.
Whether managing, studying, or simply observing insects, identification is the first step–and this book is the key. With it in hand, the marvelous microcosm right outside the house finally comes fully into view.
• Describes more than 1,400 species–twice as many as in any other field guide
• Full-color photos for most species–more than five times the number in most comparable guides
• Up-to-date pest management tips
• Organized by plant area affected and by taxa for easy identification
• Covers the continental United States and Canada
• Provides species level treatment of all insects and mites important to gardens
• Illustrates all life stages of key garden insects and commonly associated plant injuries
• Concise, clear, scientifically accurate text
• Comprehensive and user-friendly

Grammar: It’s the difference between knowing your stuff and knowing you’re stuff. Some even say it saves lives (see below). If you haven’t noticed, today is National Grammar Day (March 4), so here at Princeton University Press we are celebrating good grammar, proper punctuation, and clear communication with Frank L. Cioffi’s anti-textbook handbook, One Day in the Life of the English Language: A Microcosmic Usage Handbook.
Cioffi’s chatty and charming reference doesn’t just lay out the “rules,” but also makes a convincing case for why good grammar and usage matter. Cioffi argues that Standard Written English (also known as “formal English”) is vital for success in professions where exactness and clarity carry great importance, and he also proposes that correct English can foster a more honest, ethical, and functional culture of communication.
The book draws on some three hundred real-world sentences printed in eleven newspapers and six weekly magazines and published on a single, typical day (December 29, 2008). Cioffi emphasizes that English usage is continually evolving and he debunks some of the most popular grammar “rules.” Is it acceptable to end a sentence with a preposition? It is. Can you start a sentence with a conjunction? You can. Is it “correct” to use split infinitives. Sure.
What do you think? Does “formal” English still matter in the post-Twitter world?
Check out the introduction and let us know.
We’ve also been tweeting out #NationalGrammarDay #protips from the book today.
Happy National Grammar Day!
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
“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
The Collected Papers of Albert Einstein is one of the most ambitious publishing ventures ever undertaken in the documentation of the history of science. Selected from among more than 40,000 documents contained in Einstein’s personal collection, and 15,000 Einstein and Einstein-related documents discovered by the editors since the beginning of the Einstein Project, The Collected Papers provides the first complete picture of a massive written legacy. When completed, the series will contain more than 14,000 documents as full text and will fill thirty volumes. The volumes are published by Princeton University Press, sponsored by the Hebrew University of Jerusalem, and supported by the California Institute of Technology.

Steven Pinker, author of How the Mind Works, The Blank Slate, and The Sense of Style: The Thinking Person’s Guide to Writing in the 21st Century, was recently featured in The New York Times Sunday Book Review to, well, review books (among other things). Pinker covers everything from the current books sitting beside his bed on his nightstand to his dream literary dinner party, but one question and answer caught the Press’s attention in particular.
When asked if there were “any unexpected gems you came across” while researching his latest book “The Sense of Style,” Pinker names Mark Turner and Francis Noël Thomas’s Clear and Simple as the Truth. “Their model of ‘classic prose’ — the writer directs the reader’s gaze to something in the world — elegantly captures the differences between vigorous and turgid writing,” explains Pinker in the interview.
Not long after the Times interview (literally one day later) Pinker was published in The Chronicle Review of Higher Education for his explanation of why academics stink at writing. Here, Pinker turns to Turner and Thomas for help framing his argument. “In a brilliant little book called Clear and Simple as the Truth, the literary scholars Francis-Noël Thomas and Mark Turner argue that every style of writing can be understood as a model of the communication scenario that an author simulates in lieu of the real-time give-and-take of a conversation.”
“They distinguish, in particular, romantic, oracular, prophetic, practical, and plain styles, each defined by how the writer imagines himself to be related to the reader, and what the writer is trying to accomplish…Among those styles is one they single out as an aspiration for writers of expository prose. They call it classic style, and they credit its invention to 17th-century French essayists such as Descartes and La Rochefoucauld.”
