Through a series of case studies spanning abo litionist \npublishing\, radical print culture\, and contemporary zine pra ctices\, it traces \nhow independent publishing and archival work function as strategies of \nself-determination\, counter-record\, and collective m emory-making across \ngenerations. In a moment marked by censorship\, disi nvestment\, and rising \nauthoritarianism\, the talk argues that working w ith and circulating archival \nmaterials is a political act—one that posit ions us not only as users of \narchives\, but as active participants in pr oducing\, shaping\, and defending \nthem.\n\n \n\nNeta Bomani is a communi ty organizer\, educator\, and zine maker. She is the \nco-director of prog rams at the School for Poetic Computation and co-director \nof Sojourners for Justice Press—an imprint of Haymarket Books.

For a po sitive integer d\, let p_d(n) := 0^d + 1^d + … + n^d\; \ni.e.\, p_d(n) is the sum of the first d-th powers up to n. It’s well known \nthat p_d(n) is a polynomial of degree d+1 in n. While this is usually proved \nby induct ion\, once d is not small it’s a challenge as one needs to know the \npoly nomial for the inductive step. In this talk\, we show how this difficulty \ncan be bypassed by giving a simple proof that p_d(n) is a polynomial of \ndegree d+1 in n by using L’Hopital’s rule\, and show how we can then \nd etermine the coefficients by Cramer’s rule. *\n\n \n\n  DTSTART;TZID=America/New_York:20260430T121500 DTEND;TZID=America/New_York:20260430T131000 LAST-MODIFIED:20260424T135647Z LOCATION:Pardee 217 SUMMARY:MAAD talk - Sums of Powers by L'Hopital's Rule URL;TYPE=URI:https://calendar.lafayette.edu/node/71072 END:VEVENT BEGIN:VEVENT UID:calendar.71273.field_date.0@calendar.lafayette.edu DTSTAMP:20260514T004616Z DESCRIPTION:*The Math Dept Coffee Hour is a weekly informal gathering of st udents and \nfaculty every Thursday in Pardee 218.  Please join us for our last/ /coffee \nhour of the semester this Thursday @ 3 pm in Pardee 218.  We'll have coffee\, \ntea\, hot chocolate\, snacks\, and at least one dog :)  All are welcome!* DTSTART;TZID=America/New_York:20260430T150000 DTEND;TZID=America/New_York:20260430T160000 LAST-MODIFIED:20260428T174326Z LOCATION:Pardee 218 SUMMARY:LAST Math Dept Coffee Hour!

In this workshop\, you will build your own curved surface \nusing simple materials like paper\, cardstock\, and tape. No prior math \nbackground is needed. If you can cut and tape\, you are r eady to participate.*\n\n*We will experiment with different shapes\, such as equilateral triangles\, \nsquares\, and polygons\, and see how they fit together. As you build\, you will \nnotice that some combinations lie fla t\, while others begin to curve and \ntwist. This is a direct way to explo re ideas from hyperbolic geometry\, where \nspace behaves differently from the flat surfaces we are used to.*\n\n*You will be able to construct and take home your own model. Come try \nsomething creative and see what happe ns when polygons refuse to stay flat.*\n\n \n\n  DTSTART;TZID=America/New_York:20260430T153000 DTEND;TZID=America/New_York:20260430T163000 LAST-MODIFIED:20260424T173510Z LOCATION:Pardee 218 SUMMARY:Building Curved Geometry: A Hyperbolic Plane Workshop URL;TYPE=URI:https://calendar.lafayette.edu/node/71267 END:VEVENT END:VCALENDAR
