Why do we need proofs?

Dr. Ihor Stasyuk

Abstract: Many famous conjectures in mathematics can be verified using computers for very large groups of objects they deal with. Examples include Fermat’s Last Theorem (proved by Andrew Wiles in 1993) and (still unproved) Goldbach’s conjecture stating that every even integer greater than 2 is a sum of two primes. There are other important conjectures that can be checked in many special cases. The natural question that arises is: do we still need to prove a conjecture if it can be verified (by computers or otherwise) for very large numbers or for many possible cases? The goal of this talk is to outline several (counter)examples that hopefully will convince you that the answer to this question is “yes”.​

Body:

Friday, February 16, 2018 1:15 pm to 2:30 pm, A129

Infinite series

Dr. Alex Karassev

Abstract: In many mathematical problems a solution can be expressed as the sum of a series, a summation that has infinitely many terms. We will discuss series through the history of mathematics, consider their general properties, and look at interesting examples. In particular, we will talk about the Basel problem, the question posed in the 17th century asking for the precise sum of reciprocals of the squares of the natural numbers. We give an outline of the solution obtained by Leonhard Euler in 1735.​

Body:

Friday, April 20, 2018 1:15 pm to 2:30 pm, A129

Three classical theorems

Dr. Vesko Valov

Abstract: We will talk about the three most famous geometric constructions, impossible to perform using compass and straightedge. The problems of squaring the circle, doubling the cube, and angle trisection have been known for over 2000 years, but impossibility of these constructions has been completely proved only in the 19th century. Attempts to solve these problems led to significant discoveries in geometry, algebra, and number theory.​

Body:

Friday, May 25, 2018 1:15 pm to 2:30 pm, A129

Quantum dot nanophotonics

Dr. Ali Hatef

Abstract: Quantum dots (QDs) are nanoscale semiconductor materials with a unique size-tunable optical property. These unique size dependent qualities lead to a narrow photoluminescence spectrum in the range of visible to infIn this talk we present a brief description of QDs and their associated optical properties. We also show how the coupling of QDs with the other nanostructures can dramatically alter the QDs photoluminescence for further development of QDs for each respective application.

Body:

Friday, November 17, 2017 1:15 pm to 2:30 pm, A129

Photoacoustic response from metallic nanoparticles irradiated by pulsed laser in water

Dr. Ali Hatef

Abstract: Metallic nanoparticles (MNPs) have received growing interest over the last decade as unique contrast agents in photoacoustic (PA) imaging technique for biomedical applications. In this presentation, we talk about the fundamentals of PA imaging and show how the presence of the MNPs improve the contrast of the PA images for the detection of tumors in their early stages of development.​
