[Aspuru-Guzik group list] [IACS-events] IACS Seminar on Friday, 2/6--- "Orderly Randomness: Quasirandom Numbers and Quasi–Monte Carlo"

by Baker, Natasha

Date: Friday, February 6, 2015 Location: Maxwell Dworkin G115, 33 Oxford Street, Cambridge MA 02138 Speakers: Brian Hayes, IACS Associate Time: Lunch 12:30pm; talk 1:00pm Title: Orderly Randomness: Quasirandom Numbers and Quasi–Monte Carlo Abstract: Modern computing has an insatiable appetite for randomness. Cryptography and other kinds of adversarial computation demand “true” random numbers, which have three key properties: They are unpredictable, uncorrelated, and unbiased. Most other applications rely on pseudorandom numbers, which give up unpredictability but are still uncorrelated and unbiased. A third kind of randomness is even weaker. Quasirandom numbers are neither unpredictable nor uncorrelated; they claim only to be unbiased. They don’t even “look” random. Nevertheless, in some circumstances quasirandom numbers seem to be superior to pseudorandom ones. For example, they allow faster convergence or better error bounds in certain Monte Carlo simulations. Although quasirandom numbers have been known since the 1950s, some of their useful properties have been recognized only in the past few years, and they are not yet fully understood. Free and open to the public. No registration required. Speaker Bio: Brian Hayes is Senior Writer and columnist for American Scientist magazine and an Associate of SEAS. He writes mainly on mathematical and computational themes both for American Scientist and for his weblog bit-player.org<http://bit-player.org/>. In the 1970s and 80s he was an editor of Scientific American, and later he edited American Scientist. He has been a visitor at the Mathematical Sciences Research Institute in Berkeley and at the International Centre for Theoretical Physics in Trieste. A collection of Hayes’s columns, titled Group Theory in the Bedroom, and Other Mathematical Diversions<http://grouptheoryinthebedroom.com/>, was published by Hill and Wang in 2008. He is also the author of Infrastructure: A Guide to the Industrial Landscape<http://industrial-landscape.com/index.html> (W. W. Norton, 2005; second edition 2014). *********************** UPCOMING SEMINARS 2/13 Ray Jones (IACS Lecturer) on "Connectomics: extracting neural connectivity from very large data sets" Click here<https://lists.seas.harvard.edu/mailman/listinfo/iacs-events> to subscribe to our events list. _______________________________________________ Iacs-events mailing list Iacs-events(a)seas.harvard.edu https://lists.seas.harvard.edu/mailman/listinfo/iacs-events

[Aspuru-Guzik group list] [Aspuru-meetings-list] Group Meeting, 2/5 Div. Room, 3pm

by Jennifer Wei

Hi everyone, This week, Adrian will be giving us group meeting. Please see below for the title and abstract of his talk. *Also, please note the later group meeting time: 3pm.* Jennifer --------------------------------------------- Predicting and measuring Gibbs free energies of metabolic reactions There exist ~6000 metabolic reactions in cells, but we only have measurements of equilibrium constants (Keq) for around 10% of these. System biologists and metabolic engineers would like to get their hands on accurate values for these thermodynamic parameters. I will talk about our work in two fronts: 1) Designing experimental approaches for high-throughput measurements of equilibrium constants (in collaboration with Arren Bar-Even at the Max Planck Institute) 2) Efforts to predict Keq's using quantum chemistry, with a focus on new small basis set (HF-3C) and linear scaling coupled cluster (DLPNO) methods. _______________________________________________ Aspuru-meetings-list mailing list Aspuru-meetings-list(a)lists.fas.harvard.edu https://lists.fas.harvard.edu/mailman/listinfo/aspuru-meetings-list

[Aspuru-Guzik group list] EFRC slides

by Alan Aspuru-Guzik

Dear Excitonics group members, I am asking Sam to *collect* all the EFRC review slides (and any backup slides you have that may be useful) in a single PPTX file for me to use to prepare a presentation for this Thurdsay. So If possible, can you guys give them to Sam *today* so I can work on it tonight or tomorrow morning?

[Aspuru-Guzik group list] Small samsung phone

by Alan Aspuru-Guzik

Dear group members, I found a small Samsung phone in my office. It is in Cynthia's office right now if you lost it. I can open it for you if the phone is yours. It has no battery anymore so I could not see who was the owner.
