Math Colloquium today
by David Wright 30 Sep '22

30 Sep '22

Hi: There is a Colloquium today in MSCS 101 (the big room on the first floor) at 3:30 PM: Refreshments at 4:30 in the lounge. Speaker Paul Dawkins, Texas State University Title: A Research-based approach to the teaching and learning of logic for the purposes of learning mathematical proving Abstract below: Hope to see you there David Wright Abstract: Based on eight years of teaching experiments both in laboratory and whole-class settings, we (Dr. Kyeong Hah Roh and I) have developed a novel approach to teaching logic for introduction to proof courses. We proceed from constructing property-based set relationships, to a theory of statements rooted in set-theory, to basic proof structures (direct, contrapositive, and biconditional). By focusing on sets throughout, we maintain students’ fundamental intuition that statements and proofs refer to objects, not to mere truth values. By comparing and contrasting statements and proofs, we build the logical structures on students’ existing reading competencies. By always beginning with sets of objects unified by some property, we support students in connecting logic and proof to mathematical inferences. While the theory we develop is compatible with the standard theory of logic in most introduction to proof textbooks, we argue that these unique features of our instructional sequence allow us to build on students’ existing ways of reasoning and to connect logic more directly to the proof-based activities they exist to support. (Note: This research was funded by NSF DUE #1954613 and #1954768.)

OSU Math Department Colloquium Information and Solicitation
by David Wright 16 Aug '22

16 Aug '22

Dear friends: We are planning to hold departmental colloquia on Fridays this year. I would like to invite you to make suggestions of good speakers to invite for our colloquia. Here are the possible dates for out-of-town speakers with one already claimed. Friday Sept. 23: open Friday Sept. 30: Paul Dawkins, Texas State University Friday Oct. 14: open Friday Oct. 28: open Friday Nov. 4: open Friday Nov. 18: open Friday Dec. 2: open There will also be special Math Education Seminars on Sat. Oct. 1. The Colloquium by Paul Dawkins is part of that activity. For each of the above dates, the department has reserved lodging at a local hotel for Thursday and Friday nights. The usual schedule is that a speaker comes in Thursday and departs on Saturday. However, that schedule is somewhat flexible. The department pays out-of-town speakers travel expenses, lodging, a per diem for expenses, and a small honorarium. In addition, the 7th Annual Meeting of SIAM Central States Section is being held at OSU on Saturday Oct. 1 to Sunday Oct. 2. That will be a busy math weekend in Stillwater. Please contact the co-chairs Xu Zhang and Xukai Yan for more info on those activities or go to the link https://siamcss2022.okstate.edu/ In addition there are invitations being processed now, and so if you would like to invite someone, please check the schedule at https://www.mathdept.okstate.edu/announce/ and please send me an email about your proposed speaker and dates. There is also a Physics Department Colloquium by a mathematician with expertise in Quantum Computing: Harry Buhrman, University of Amsterdam, Thursday August 25, in PS 110. That will count for our colloquium activity in the first week of term. The other Fridays conflict with football game weekends, which make it nearly impossible to arrange lodging, and there are other inconveniences as well. However, we invite new faculty and postdoctoral faculty to consider offering general colloquia to introduce themselves and their subjects to the general department. Please email me if you think you would like to give a colloquium. The possible dates are Friday Sept. 2 Friday Sept. 9 Friday Sept. 16 Friday Oct. 7 Friday Nov. 11 Friday Dec. 9 If a crusty old senior faculty member has a good idea for a colloquium, please consider volunteering as well. Ideally, a colloquium talk should have value for every department member including undergraduate math majors, graduate students, and mathematicians in any field. It is fair for a speaker to assume for half the talk that the audience knows basic abstract algebra, analysis, topology, differential equations, and other subjects of the level of first-year graduate mathematics. Anything specialized beyond that should be carefully introduced by the speaker. Usually the final 10 to 15 minutes offer a chance for the speaker to get to the meat of their subject and then they may make more demands of their audience. The normal time limit for our colloquium talk is 50 minutes, with 10 minutes after that for questions. A reception with refreshments will be held afterwards in the department lounge. A colloquium visit can also include time for a seminar talk, in which the speaker can discuss deeper research matters. For that, it may be necessary to book an extra day of lodging. Of course, we will have to be aware of how the pandemic is progressing, and there may be guidance about wearing masks, etc., as we move through the fall term. Please think of someone to invite or invite yourself and send me an email. Best wishes, David Wright david.wright(a)okstate.edu

Retirement
by Anthony Kable 31 May '22

31 May '22

Hi everyone. Bruce Crauder has decided to retire from OSU. His retirement will be effective in January 2023, so Fall 2022 will be his last semester as an active member of the faculty. Bruce's contributions to mathematics and to the University have been many and varied. His long service as Associate Dean for Instruction and Personnel helped to keep the College on track during some difficult times, and he was twice Interim Dean. He served as Interim Director of the OSU Museum of Art for three years while the Postal Plaza renovation was underway and was instrumental in guiding that project to success. He and his coauthors have written four textbooks in support of mathematics curriculum reform efforts, and those books have been influential and widely adopted. Of course, Bruce also contributed through research in algebraic geometry, through his teaching, and in many other ways as well. Please join me in thanking Bruce and in wishing him the best for his last semester at OSU and beyond.

Retirement

Hi everyone. I am writing to let you know that Birne Binegar will be retiring on September 1. Birne had a long career at OSU and made significant contributions in research, teaching, and service. Let me mention just two highlights. First, he was involved in the ATLAS of Lie Groups project and helped move that collaboration towards its successful computation of the Kazhdan-Lusztig polynomials for split E8. Secondly, he played a vital leadership role on Faculty Council during some very challenging times, and managed to build consensus whilst protecting faculty interests. I'm sure you'll all join me in thanking Birne and wishing him the best for the future.
