Introduction:

“Supersymmetry” is a term from physics which describes an extra symmetry among the elementary particles of physics. It hypothesizes that there exists superpartners between the two types of particles, bosons and fermions. 

The term “supersymmetry” also appears in mathematics, but the meaning can seem to be different from the meaning in physics. For example, a supermanifold is a geometrical space which is like a manifold but with invisibly small extra dimensions. 

In my talk, firstly, I will give an example of how supersymmetry in physics and supersymmetry in mathematics are related. Secondly, since I am a mathematician myself, I will describe how supergeometry is well-motivated independently of physics. At its core, supergeometry is related to taking squareroots. For example, what is the squareroot of –1, and how does this relate to supersymmetry? Part of the answer is the number system called the octonions, which is an 8-dimensional extension of the real numbers.

Introduction:It has only been about a 100 years since humanity has realized that our Milky Way galaxy is not the whole Universe, but forms a mere speck in its large expanse.

A large fraction of the ‘fuzzy objects’ classified by Messier in the 17th century actually turned out to be galaxies much further away from our own little home galaxy.

Since then, our understanding of galaxies has grown with the growth of our knowledge in a variety of different scientific domains, all of which have been found to influence the properties of these amazing structures. The interplay between gas dynamics, gravitation, cosmology and stellar physics has been found to determine why galaxies look the way they do.

We will take a journey from the earliest generation of galaxies less than a billion years after the big bang, to the latest which includes our Milky Way. We will see how the conditions in the early Universe, drastically different, led to galaxies looking very different from how they are now. Nevertheless, the same physical processes have been dictating them, and hence making all galaxies across cosmic time fundamentally similar to one another. Galaxies, so very different but yet the same: we will see how these ‘fuzzy objects’ tell us a tale of the ever changing state of our Universe.
