Outstanding choices!
Interesting bit of sociology: They are really studiously avoiding any mention of quantum computing. First and only mention came in the last few words of the presentation by Johansson.

Bad Policy: Subjecting PhD students and postdocs to 4-year visa limits, subject to immigration officials' review. This bureaucratic overregulation will reduce US competitiveness and weaken US science. There needs to be more awareness and discussion of this terrible idea

Both the House and Senate Committees on Appropriations have now passed funding for science agencies with moderate cuts and flat funding, respectively. Both bills are quite far from the president's budget request, which proposes massive cuts to science funding.
The Senate Committee on Appropriations gave the first signs Congress will push back on Trump's proposed budget cuts to science and instead keep funding flat, though an unrelated issue (the location of the FBI headquarters) stalled any vote today.

RIP Ray Laflamme, gone too soon.
Ray was a stellar scientist, the founding director of the IQC and of CIFAR's Quantum Information program, but more importantly a warm & generous human who built community and helped many (particularly junior researchers).
May his memory be a blessing.

Happy to see our book "Why Nobody Understands Quantum Physics" published in English www.panmacmillan.com/authors/fran.... Unlike other popular science books, we explain quantum and its applications in the way working physicists use and understand them, without shying away from the many-body problem.

Now explore probabilistic algorithms in this world."
