The topology of data

The paper that I wish to discuss today is An Introduction to Topological Data Analysis: fundamental and practical aspects for data scientists, by Frederic Chazal and Bertrand Michel. Topological data analysis is an exciting new field, and this paper can be understood by people from a wide range of backgrounds. Notation: For this paper, denotesContinue reading “The topology of data”

CRISPR- A review

The paper that I want to talk about today is The CRISPR Toolkit for Genome Editing and Beyond by Mazhar Adli, published in Nature Communications in 2018. My rather elementary knowledge of Biology did not make this easy, and it was fun to watch countless youtube videos to try and get to grips with thisContinue reading “CRISPR- A review”

Notation in Riemannian Geometry

I have always found the notation in Riemannian Geometry to be very confusing. How and why are we doing the things that we’re doing? What does all this abstruse notation mean? This is my attempt to write a helpful guide for anyone starting out in this field. Why the affine connection? Why this notion ofContinue reading “Notation in Riemannian Geometry”

Neuromorphic Computing

I’ve searched far and wide for an easy to understand review paper on Neuromorphic computing, and finally got lucky with Neuromorphic Computing: From Materials to Systems Architecture. This is a report from a roundtable conference organized in 2015 to discuss the future of Neuromorphic computing. The organizing committee of the conference comprised of Evan SchullerContinue reading “Neuromorphic Computing”

How, on Earth, we took a picture of a black hole

The paper that I will be writing about today is Computational Imaging for VLBI Reconstruction by Katie Bouman, et al. The image processing algorithm explained in this paper was the reason for the first photo that humanity ever took of a black hole. Introduction At the time that this paper was written, there was anContinue reading “How, on Earth, we took a picture of a black hole”

Why is chlorophyll green?

The paper that I want to discuss today is Quieting a Noisy Antenna Reproduces Photosynthetic Light Harvesting Spectra, by Arp, Aji, Gabor et al. I first read about this in a Quanta article. The scientific question that was answered in this paper was amazing- why are plants green? So, why indeed are plants green? OneContinue reading “Why is chlorophyll green?”

Jagdish Chandra Bose and Plant Neurobiology

The paper that I’ll be discussing today is Jagdish Chandra Bose and Plant Neurobiology by Prakash Narain Tandon, a celebrated Indian scientist. When I was a school student in India, I often came across JC Bose’s claims of plants being sentient beings, having nervous systems, etc. However, these things were never part of the officialContinue reading “Jagdish Chandra Bose and Plant Neurobiology”

The science of going in circles on doughnuts

The paper that I’m going to be reviewing today is A Topological Look at the Quantum Hall Effect. It explains an amazing coming together of topology and quantum physics, of all things, and provides a review of very important, Nobel prize winning work in Physics. The Hall Effect We all learned in high school thatContinue reading “The science of going in circles on doughnuts”
