PhDs: the tortuous truth | Careers - Nature.com

Chris Woolston, freelance writer in Billings, Montana reports, Nature’s survey of more than 6,000 graduate students reveals the turbulent nature of doctoral research.

Getting a PhD is never easy, but it’s fair to say that Marina Kovačević had it especially hard. A third-year chemistry student at the University of Novi Sad in Serbia, she started her PhD programme with no funding, which forced her to get side jobs bartending and waitressing. When a funded position came up in another laboratory two years later, she made an abrupt switch from medicinal chemistry to computational chemistry. With the additional side jobs, long hours in the lab, and the total overhaul of her research and area of focus, Kovačević epitomizes the overworked, overextended PhD student with an uncertain future.

And yet she could hardly be happier. “I think I’m exactly where I need to be,” she says. “I love going to work each day. I have lots of things to do, but I’m not stressed. I can’t imagine anything else that would bring me this much joy.”

The results of Nature’s fifth survey of PhD students bear out Kovačević’s experience, telling a story of personal reward and resilience against a backdrop of stress, uncertainty and struggles with depression and anxiety. The survey drew self-selecting responses from more than 6,300 early-career researchers — the most in the survey’s ten-year history. The respondents hail from every part of the globe and represent the full spectrum of scientific fields...

Institutions also have much to learn. This survey and others like it should point the way for institutions trying to adapt to the needs of their students, Gotian says. Even though a majority of students are satisfied with their programmes, she says, their complaints and frustrations deserve close attention. “We don’t want to run programmes the way we did 20 years ago,” she says. “People have changed, technology has changed, the job market has changed. We need to constantly evolve.”

A personality quiz for fans of math and history: Are you a Newton or a Leibniz? | Science - Ars Technica

Math teacher Ben Orlin writes and draws the (aptly named) blog Math With Drawings and is the author of a new book, Change Is the Only Constant: The Wisdom of Calculus in a Madcap World. To mark its publication, he devised this entertaining accompanying quiz. You can read the Ars interview with Orlin here.

Ars Technica's Jennifer Ouellette, senior reporter says, Isaac Newton and Gottfried Leibniz 
are like night and day, or derivatives and integrals.
Arch-rivals Isaac Newton and Gottfried Leibniz famously fought over the credit for inventing calculus.
Isaac Newton and Gottfried Leibniz have a lot in common. Birthdates in the 1640s. Fatherless childhoods. Colossal egos. Show-stopping wigs. Most of all, each had the honor of bringing calculus into the world. But when it comes to personalities, Newton and Leibniz are like night and day, or England and France, or derivatives and integrals. They’re rivals. Opposites, even. Do you belong on #TeamNewton or #TeamLeibniz?

Math Research: How Does it Work? | Campus - The UTD Mercury

Take an inside look at how UTD's mathematical scientists operate, solve problems using high dimension math, explains, according to Breanna Shen, Mercury Staff.

When people think of research, they imagine a scientist in a white lab coat pipetting chemicals or culturing cells on a petri dish. But when asked to consider “math research,” what comes to mind? What does pure math research entail?

This fall, the School of Natural Sciences and Mathematics inducted seven new tenured and tenure-track faculty. Among them, Baris Coskunuzer and Stephen McKeown conduct research in math, while Qiwei Li conducts statistics research.

“Pure mathematicians are not really interested in the real-life applications,” Coskunuzer said. “They are trying to solve nice puzzles, which give you interesting relationships between objects.” 

Coskunuzer got his first taste of math as a high schooler in Turkey, where he enjoyed classes in abstract math. He majored in math in college, and as a Ph.D. student at Caltech, his advisor introduced him to geometric topology... 

In contrast with pure math research, Li said, statistics research centers on application, especially in medicine or biology.

“Statistics is the science about data, because the data can reveal lots of interesting things about the body and the world,” Li said...

Li uses Bayesian statistical tools to draw conclusions in two areas of application, digital pathological images and microbiomes, which are collections of microorganisms, using both data and prior knowledge. High resolution images of pathological tissues can be analyzed by a deep learning AI to identify different types of cells, Li said. The patterns of cells are statistically quantified and used to predict patient survival outcome.

Mathematician discovers method to simplify polymer growth modelling | Mathematics - Phys.Org

A mathematician from RUDN University has proven that there are no solutions to functional differential inequalities associated with the Kardar-Parisi-Zhang (KPZ)-type equations, nonlinear stochastic partial differential equations that arise when describing surface growth by Phys.Org.

The obtained conditions for the absence of solutions will help in studies of polymer growth, the theory of neural networks, and chemical reactions. The article was published in Complex Variables and Elliptic Equations

The main difficulty with nonlinear partial differential equations is that many of them are not solved exactly. For practical purposes, such equations are solved numerically, and the questions of the existence and uniqueness of their solutions become problems over which scientists have been struggling for decades, and sometimes centuries. One of these problems—Navier-Stokes existence and smoothness—was included in the famous list of Millennium Prize problems: The Clay Mathematical Institute in the U.S. offers a prize of $1 million for solving any of these problems.

Any partial differential is defined in a certain area, e.g., on a plane or in a sphere, or in space. Usually, it is possible to find a solution to such equations in a small neighborhood of a point, i.e., a local solution. But it may remain unclear.

RUDN University Mathematical Institute mathematician Andrei Muravnik used the method of inequalities. He generalized the existing theorems to the quasilinear case that arises in the study of the KPZ-type equations. The conditions obtained not only limit the set of possible solutions to the KPZ-type equations, but are also are necessary for the solvability of problems that arise in practice. In particular, these results help in solving the problems of surface growth when modeling the behavior of polymers, and can also be used in the theory of neural networks.

75 books from university presses that will help you understand the world | Culture - Vox.com

These books will help you understand the world and make it a better place by Constance Grady, Staff Writer at Vox.

Under the Donald Trump administration, misinformation is as constant and pervasive as oxygen. Which means that rigorously researched and fact-checked books are a deeply attractive resource — but they’re not always easy to find. 

Traditional publishing doesn’t have a built-in fact-checking system. It leaves the task (and expense) of fact-checking entirely to its authors. The result is that every few months, a major book is torpedoed by the news that it is riddled with errors.

The latest version of this story came earlier this week, when a new book from Hachette’s conservative imprint Center Street claimed that under President Barack Obama, the CIA complained of “nonstop PC [political correctness] meetings.” That claim then became a Fox News headline, and kicked off a round of right-wing outrage as stories in conservative outlets like the Washington Examiner followed. PC in this context, however, did not stand for “political correctness.” It stood for “principals committee” meetings, and when news of that error hit Twitter, it drove another round of outrage, this time from the left, with mocking headlines popping up on progressive outlets across the web...

University presses get peer reviewed. That’s a level of quality control most books don’t have.
“University press books are consistently the most reliable source of longform content based on deep research that has been vetted by experts,” says Kathryn Conrad, director of the University of Arizona Press and president of AUPresses.

Unlike traditional publishers, university presses peer review their books, meaning that they send each book to scholars who are experts in the subject matter to obtain their seal of approval before they send a book to the printers. (Disclosure: I used to work at a university press.) When the system works the way it’s supposed to, readers of a university press book can trust that a team of experts has ensured that what they’re reading is accurate and up to date...

The books on the list cross disciplines from linguistic anthropology to environmental studies to history to border studies to sociology, but all of them are designed to be readable even to a non-scholarly audience. That’s not always the case for university press books, many of which are written for scholars who already know all the jargon and backstory of a given field — but almost all university presses do aim to publish trade books for a lay audience alongside their academic books, and the trade books all get peer reviewed, too.

13 best Asian American children's and young adult books 2019 | Asian America - NBC News

The list includes a retelling of 'Little Women,' a story set amid Kuala Lumpur's 1969 riots, and an illustrated biography of Disney's first Asian American animator by Lakshmi Gandhi, Freelance reporter and Social Media Manager at NBC News

Asian American books for children and young adults to read in 2019
Recent years have seen an onslaught of books featuring both diverse characters and diverse experiences, including from and about an Asian American lens.
For parents eager to raise a young reader, filling your home with books your child can connect to is essential.

“You want books all throughout your house — not just that one shelf in the living room, but the dining room, the bathroom, [and so on],” Maria Russo, co-author of “How To Raise a Reader,” told NBC News in October. She discussed how to build and nurture your child's love of literature.

For Russo, the most important thing parents of readers can do is make sure reading is seen as accessible and fun. “Having a lot of books in your own house and creating an environment where books are nearby that they can stumble on sets a family culture [of reading],” she said...

As we approach the end of the year, we’re looking back at some of the best children’s and young adult books to be released in 2019 by and about Asian Americans. From the illustrated story of a Disney legend who was instrumental in creating “Bambi” to an award-nominated young adult novel about a Filipino American teen caught between two worlds, here are some books to consider placing on your bookshelves this winter.

The Greatest Unknown Intellectual of the 19th Century | Science & Technology - The MIT Press Reader

Photo: Emil du Bois-Reymond
Emil du Bois-Reymond proclaimed the mystery of consciousness, championed the theory of natural selection, and revolutionized the study of the nervous system. Today, he is all but forgotten, argues Gabriel Finkelstein, Associate Professor of History at the University of Colorado Denver.

Unlike Charles Darwin and Claude Bernard, who endure as heroes in England and France, Emil du Bois-Reymond is generally forgotten in Germany — no streets bear his name, no stamps portray his image, no celebrations are held in his honor, and no collections of his essays remain in print. Most Germans have never heard of him, and if they have, they generally assume that he was Swiss.
But it wasn’t always this way. Du Bois-Reymond was once lauded as “the foremost naturalist of Europe,” “the last of the encyclopedists,” and “one of the greatest scientists Germany ever produced.” Contemporaries celebrated him for his research in neuroscience and his addresses on science and culture; in fact, the poet Jules Laforgue reported seeing his picture hanging for sale in German shop windows alongside those of the Prussian royal family. 

Those familiar with du Bois-Reymond generally recall his advocacy of understanding biology in terms of chemistry and physics, but during his lifetime he earned recognition for a host of other achievements. He pioneered the use of instruments in neuroscience, discovered the electrical transmission of nerve signals, linked structure to function in neural tissue, and posited the improvement of neural connections with use. He served as a professor, as dean, and as rector at the University of Berlin, directed the first institute of physiology in Prussia, was secretary of the Prussian Academy of Sciences, established the first society of physics in Germany, helped found the Berlin Society of Anthropology, oversaw the Berlin Physiological Society, edited the leading German journal of physiology, supervised dozens of researchers, and trained an army of physicians...

Detecting brain-beats is not yet common practice in barbering, but it is in medicine. In this respect Kierkegaard was right: The march of technology has been steady to the point of routine. Every refinement of du Bois-Reymond’s electrophysiological apparatus, from the vacuum-tube amplifier to the microelectrode to the patch clamp, can be thought of as a footnote to his original technique. Such achievement in instrumentation is anything but small: Two years after Kierkegaard’s taunt, du Bois-Reymond contended that physiology would become a science when it could translate life processes into mathematical pictures. The imaging devices associated with medical progress — the EKG, the EEG, the EMG, and the CT, MRI, and PET scanners — seem to vindicate his prediction. But success is not a category of analysis any more than failure. To make sense of why du Bois-Reymond devoted the whole of his scientific career to one problem, it helps to understand his deepest motivations...


How, then, could someone so famous and so important end up so forgotten? Let me suggest three kinds of answer. The first has to do with the histories that disciplines write about their origins. These usually take the form of the classical Greek myth of the Titanomachy, with a Promethean figure (the disciplinary founder) aligning with the Olympian gods of truth against an older and more barbaric generation (here symbolized by Kronos, or tradition). Psychology provides a perfect case in point. In Russia the discipline’s heroes are the two Ivans, Pavlov and Sechenov, with little discussion of how much they owed to Carl Ludwig’s studies of digestion or Emil du Bois-Reymond’s studies of nerve function. In Austria the hero is Sigmund Freud, and only recently has Andreas Mayer laid out just how much he learned from Jean-Martin Charcot’s use of hypnosis. And in the United States the hero is William James, the center of a veritable industry of scholars, none of whom quite put their finger on why he moved to Berlin in 1867. James never mentioned his debt to du Bois-Reymond, perhaps because he quit his class, or perhaps because so many of his early lectures drew from du Bois-Reymond’s writings. In each case the titanic hero breaks the line of continuity, throws over the all-devouring father, and benefits humanity with his torch of reason.

No one gets left behind | Columns - INQUIRER.net

I know that there are many people who dream of finishing school, summarizes Kim Alexis V. Sta. Ana, graduate of the ALS Program of La Salle Greenhills, and is now a freshman mass communication student under the AMA University Online Education.


Fortunately, for some of us who lack the resources to acquire formal education, there is finally a solution that can benefit many of our out-of-school youth and adult learners who just want to get their hands on a diploma.

The Alternative Learning System (ALS) is a parallel learning system implemented by the Department of Education under the Bureau of Alternative Learning System that serves as a viable option to the existing formal instruction, so that learners can complete basic education in a mode that is beneficial to their distinct situation and needs. For those who do not have the chance to attend formal schooling, ALS is the substitute. Unlike in the formal education system where students are taught in a classroom within a strictly implemented time period, ALS learners are taught in places like barangay halls, private homes, community centers and even libraries, within a schedule that they themselves choose. Therefore, while formal learning is “pushed” on learners, learners are “pulled” toward informal education.

No matter what age, ethnicity, color or religion, ALS welcomes people with open arms, giving them a taste of what it is like to learn things at their own pace, or what’s convenient for them. ALS can apply to everybody: primary and secondary school dropouts, out-of-school youths, nonreaders, working individuals and even senior citizens who are interested in either brushing up or developing new skills... 

ALS has benefited me and my classmates in more ways one can imagine. I used to be so unwilling to get assistance, especially whenever I was having a hard time. But because of ALS, I have learned that there’s nothing wrong in wanting and asking for support. Achieving something on your own is triumphant, but achieving something with the people around you is transcendent. Success isn’t just something you can accomplish by yourself. It’s the guidance of other people that can take you on the right path, and that’s truly what ALS has been able to do for me. My ALS classroom has easily become my second home, and my classmates and instructors my family.

From Alice in Wonderland to the Hitchhiker's Guide: top 10 books about mathematics | Mathematics- The Guardian

From Lewis Carroll to Douglas Adams and even Dostoevsky, the imaginative possibilities of numbers have animated some dazzling fiction by Catherine Chung, author.

Sories and mathematics have always been woven together in my mind – two foundational ways of looking at the world, not incompatible but complementary. When I was growing up, my mother told me myths and fairytales at bedtime, while my father recounted stories of famous mathematicians and gave me his favourite maths riddles to try to solve. Which is maybe why in my new novel, The Tenth Muse, I try to bring the two together, while challenging the many mistaken assumptions people hold about maths. My protagonist is a brilliant and ambitious mathematician who happens to be a woman tackling one of her subject’s most pressing conundrums. 

I hope her journey provides a history of mathematics and the ways it has changed the world, the challenges women in particular have faced in trying to join its professional ranks, and a glimpse of how exhilarating it can be. My favourite kind of maths reveals the outer reaches of the imagination and how in finding a solution it is possible to illuminate an idea. Maths can shine a light on both the simplest and most complex things; the same is true of my favourite literature.
