Naslov predavanja: WHEN THE PRECISION OF MATHEMATICS MEETS THE MESSINESS OF THE WORLD OF PEOPLE

Apstrakt: Almost all mathematicians are attracted to the subject by its certainty and precision. It’s one of the most finely sharpened blades in the human cognitive armory, and it rules supreme in many parts of Physics and Engineering. It is almost as precise when applied to the activities of large groups of people, though the precision then is a statistical one that applies to the group as a whole. But can math be useful when applied to human activities on a more local scale? The answer is “yes”, but the contribution mathematics can make shifts from “providing precise answers to specific questions” to “providing data that helps a domain expert make a decision”. These newer uses of mathematics can be traced back at least as far as the early days of probability theory (concepts such as “utility”), but became prevalent much more recently when computers enabled rapid computations of large datasets. Applications in the financial markets (for example, the Black-Scholes model for pricing derivatives), manufacture, retail sales, transportation, and workplace design are ubiquitous. I’ll give two examples I have worked in: developing a framework to understand information flow and using that framework to analyze communication breakdown in the workplace—work that eventually found application in intelligence analysis.

Napomena: prof. Keith Devlin održaće još jedno predavanje tokom svog boravka u Beogradu. Predavanje će biti održano 1. marta 2018. u svečanoj sali SANU sa početkom u 11 časova.

Naslov predavanja: MATEHEMATICS IN THE 21ST CENTURY

Apstrakt: All the mathematical procedures I learned in school and at university became obsolete during my career. Except for proofs, all the exam questions I struggled with can now be solved faster, more accurately, and with much larger data sets, by freely available software applications.

Yet there are more people I the world using mathematics today than there were in my childhood, and advanced mathematics is more important today than at any time in human history. What has changed—and it has been a dramatic change—is how mathematics is done today. Mathematics educators across the globe are struggling to adapt to this new world.
