	SMMG – September 2023 Date: September 10th, 2023 Time: 12pm-2pm Location: PMA 4.102 Speaker: Shiyu Liang Title: A Taste of Knot Theory Abstract: Ever wondered about the secrets hidden in simple knots? Join us for a journey into the captivating world of knot theory! From the knots in your shoelaces to the mysteries of 3- and 4-manifolds, we'll explore it all. Get ready for an exciting adventure inspired by everyday life. This talk is designed to be fun and accessible for everyone.
	SMMG – September 2023 Date: September 24th, 2023 Time: 12pm-2pm Location: PMA 4.102 Speaker: Justin Toyota Title: The Theory of Numbers Beyond Counting Abstract: Number theory is the study of the properties of the integers, the numbers we use to count. Despite their apparent simplicity, there are a variety of deep questions one can ask about them, and their study has spurred the development of mathematics for hundreds of years. In this talk, we will explore a small sample of the riches the field has to offer.
	SMMG – October 2023 Date: Octerber 8th, 2023 Time: 12pm-2pm Location: PMA 4.102 Speaker: Paulina Hoyos Restrepo Title: Tfdvsf Dpnnvojdbujpo xjui Dszquphsbqiz Abstract: The title of this talk has been encrypted for secure communication purposes! All four words in the title also appear in this abstract; is that enough information to decipher the title? Come to our next SMMG talk to learn about Cryptography, a discipline that seeks to develop techniques to prevent third parties or the public from reading private messages. We'll do a historical overview of various cryptographic techniques, and you'll learn how to create your own encryption protocols to communicate privately with your friends!
	SMMG – October 2023 Date: October 22nd, 2023 Time: 12pm-2pm Location: PMA 4.102 Speaker: Erin Bevilacqua Title: Pólya's urn Abstract: Imagine you have an urn with w white balls and b black balls. You may have heard of sampling without replacement or with replacement, but what happens if every time you pick a ball at random you replace it with c balls of the same color? This is Pólya's urn, and in this week's talk we will discuss what happens in each of these cases. We will begin with an hour of probability related riddles to warm up before diving into this problem.
	SMMG – November 2023 Date: November 5th, 2023 Time: 12pm-2pm Location: PMA 4.102 Speaker: Jeffrey Cheng Title: Isoperimetric Sets Abstract: Abstract: Given a shape, the perimeter is the length of the boundary of the shape. For a square, the perimeter is 4 times the side length. For a circle, the perimeter is 2pi times the radius. What do you think the shape with the greatest area is, assuming that the perimeter of the shape is 1? This is a question that people have been thinking about for thousands of years. In this talk, we will answer this question, and talk about why it was so hard to answer!
