Title: Data Science Curriculum for Industry

Abstract:

John Marriott earned his PhD from UH Math in 2013 and currently works

at Boeing as a data scientist. He combines mathematical modeling,

statistics, and programming to create data products on logistics,

labor estimates, and workplace safety. He will talk about his current

work, the transition from academia to industry, and suggestions for

curriculum to prepare students for work in this field.

Title: The universal algorithm, the $Sigma_1$-definable universal finite sequence, and set-theoretic potentialism

Abstract: As shown by Woodin, there is an algorithm which will computably enumerate any finite list you want, so long as you run it in the correct universe. More precisely, there is a Turing machine $p$, with the following properties: (1) Peano arithmetic proves that $p$ enumerates a finite sequence; (2) running $p$ in $mathbb N$ it enumerates the empty sequence; (3) for any finite sequence $s$ of natural numbers there is a model of arithmetic $M$ so that running $p$ in $M$ it enumerates $s$; (4) indeed, if $p$ enumerates $s$ running in $M$ and $t$ in $M$ is any finite sequence extending $s$, then there is an end-extension $N$ of $M$ so that running $p$ in $N$ it enumerates $t$. In this talk, I will discuss the universal algorithm, along with an analogue from set theory due to Hamkins, Welch, and myself, which we call the $Sigma_1$-definable universal finite sequence.

These results have applications to the philosophy of mathematics. Set-theoretic potentialism is the view that the universe of sets is never fully completed and rather we only have partial, ever widening access. This is similar to the Aristotelian view that there is no actual, completed infinite, but rather only the potential infinite. A potentialist system has a natural associated modal logic, where a statement is necessary at a world if it is true in all extensions. Using the $Sigma_1$-definable universal finite sequence we can calculate the modal validities of end-extensional set-theoretic potentialism. As I will discuss in this talk, the modal validities of this potentialist system are precisely the theory S4.

Applied Mathematics in Action through Biostatistics

Applied mathematics is a field of constant adaptability to the world’s contingencies. Such

adaptability requires a solid training and a keen understanding of theoretical and pure

mathematical thinking—as the activity of applied thinking is vitally connected to research

in pure mathematics. One such applied mathematical field is the field of statistics. As the

world continues to rely more on data for inference and decision making, statistics and

associated data-driven fields have gained an increased recognition. The purpose of this talk

is to educate the audience about the field of statistics, about statistical involvements, and

provide examples of settings where statistical theory finds an application and where real-

world applications call for new statistical developments. The presentation further provides

some general guidance on the mathematical and computational skills needed for a

successful graduate work in Statistics or Biostatistics.
