Boston Computation Club
By Max von Hippel
The Boston Computation Club is a small seminar group focused on mathematical computer science, and computational mathematics. Its name is plagiarized from the London Computation Club. Boston Computation Club meetings occur roughly every other week, on weekends, around 5pm EDT (modulo speaker availability). The usual format is a 20m presentation followed by 40m of discussion. Some, but not all, meetings are posted on YouTube and in podcast form.
01/08/22: Covert C2 Channels with Kai Bernardini
Kai Bernardini is a professional hacker/security researcher, a mathematician, and and a lecturer in computer science at Boston University. He's also better than me at lead belay (no short-roping from Kai!). Today Kai joined us to discuss covert command and control (C2) channels. Sure, your communication might be indistinguishable from random noise. But is it indistinguishable from r/dankmemes? If not, prepare to get caught by the local sysadmin.

12/04/21: Feynman Integrals for a Mathematical Audience with Matthew von Hippel
Matt von Hippel is (a) my cousin and (b) a professor at the Niels Bohr International Academy in Copenhagen, Denmark, where he researches scattering amplitudes in gauge and gravity theories. Matt received his PhD in 2014 from SUNY Stony Brook, and from 2014 to 2017 he was a postdoctoral fellow at the Perimeter Institute. Today Matt joined us to discuss Feynman integrals. Apparently "Feynman integral" means different things to different people; the kind discussed here are those associated with "Feynman diagrams". The talk was engaging and fun, and at the end Matt fielded mathematical questions from the audience, which included both usual BCC members and some NEU mathematics faculty. This was a fun one and I encourage you to watch it, if you didn't make the live event! Matt's personal page at the NBIA is HERE. Matt's popular physics blog is HERE. Matt can be found on Twitter HERE. This talk can be found in video form HERE. You can learn more about the Boston Computation Club HERE.

10/09/21: Types in PL Research vs Types in Julia with Julia Belyakova
Julia Belyakova is a PhD student in computer science at Northeastern University, where she is currently focused on formalizing the Julia programming language. Julia's primary primary research interests are programming languages and type theory, although she also enjoys theorem proving, generic programming, functional and object-oriented programming, software engineering, programming by contracts, software testing, and as of late, human aspects of software engineering and the interaction between humans and programming languages. In short: Julia is quite the polymath. Today she joined us to discuss the Julia Language's type system, in contrast to type systems in other languages, and in programming language research papers. This was a really fun talk and also a very accessible entry-point to the topic for those without a strong PL background. We hope you enjoy! - Julia Belyakova's homepage: https://julbinb.github.io/ - The Julia language: https://julialang.org/ - The Boston Computation Club: https://bstn.cc/ - This talk but as a video: https://youtu.be/JNxrX2XvZIY

07/10/21: The Illogical Nature of Chemical Nomenclature [Biology Café #1]
"Café Events" are small, informal events where we discuss our research and our (perhaps, unfulfilled) research interests. Our ongoing "Biology Café" series is exactly that, but focused on topics at the intersection of biology and computation. Today's presentation by Sophia von Hippel covered the open, and very important, problem of developing a mathematical language for chemistry. Chemistry has a great diagrammatic syntax, but a (or, multiple) terrible prose representation. Sophia presents the problem in clear and careful detail with examples, and then we discuss. TL;DR: we don't solve the problem. Sophia is currently pursuing a BS in Chemistry at the University of Arizona (with Honors). She previously interned with NASA and served as a COVID-19 vaccinator. She is also an Emergency Medical Technician with the University of Arizona Emergency Medical Services (UAEMS). You can also view this presentation as a video on YouTube [HERE].
