Due to a grant of the Luxembourg National Research Fund (FNR), we are happy to have several vacancies for PhD candidates at the Mathematics department of the University of Luxembourg. Those are 4-year attractive positions.

The deadline for applications is 30 April 2017.

There is more information and a button to apply on the following page:

Please address any question to:

We would be grateful if you could share the information with any potentially interested student.

Do you know any good textbook on basic linear algebra or analysis?

From next september we'll have to give elementary mathematics courses (linear algebra 1 & 2, analysis) for computer science majors, in english. I'm therefore looking for good english-language textbooks (either published or available online). Our courses tend to be more complete than in most places in the US, so we would need textbooks containing full definitions and proofs, and if possible some interesting exercises, while not being too long or extending too far beyond what we'll be teaching.

Thanks in advance for any help!

Steven Weinberg on the continuing challenges of quantum mechanics.

"The development of quantum mechanics in the first decades of the twentieth century came as a shock to many physicists. Today, despite the great successes of quantum mechanics, arguments continue about its meaning, and its future."

An educated justification of the common core approach to K12 mathematics. I'm not convinced, but it's good to understand why intelligent experts thought this up.

Some thoughts about the challenge presented to the economy by rapid progress in artificial intelligence.
"[...] this report suggests and discusses
below three broad strategies for addressing the impacts of AI-driven automation across the whole
U.S. economy:
1. Invest in and develop AI for its many benefits;
2. Educate and train Americans for jobs of the future; and
3. Aid workers in the transition and empower workers to ensure broadly shared growth."

New: up to four postdoctoral positions in geometry are currently open for 2-year positions, possibly extendable to a third year, starting in Sept 2017. Applications are on the university portal. Deadline for application is Jan 30, 2017. Those positions are particular attractive (low teaching load, active and dynamic environment, budget for travel and invitations, very competitive salary). In case you know someone who might be interested, please spread the word!

About an interesting book by a biologist on the growing role of narcicism in academia. Mathematics seems to be an exception, but I do see this a lot in other fields.

Another indications that girls need to be encouraged, even more than boys, when studying mathematics.

A fascinating glimpse into the complex life that's going on below the ground in a forest.

Interesting answers to a good question: why exactly is mathematics a good intellectual training for non-mathematical tasks?
Can you relate to these six?

Nearly dismissed this as one of "those" essays about the importance of #mathematics for everyone,, but the more I read of this post by +Jeremy Kun in +Medium, the more I cheered him on. His premise? That there exist concrete, unambiguous skills that students of mathematics, when properly taught, will practice and that will come in handy in their lives outside of mathematics. Not an exhaustive list, but certainly a good one to start with.
