# DAE-HEP 2018 – Preons, Fermions and All That

The 23th DAE-BRNS High Energy Physics Symposium was held at IIT Madras from Dec 10 – Dec 14. It was an interesting event. I met lots of very smart people. My abstract based on my paper had been selected for a talk in the “Formal Theory” parallel session on Dec 11. Interestingly the talk preceding… Continue reading DAE-HEP 2018 – Preons, Fermions and All That

# Zotero vs Mendeley

There are two nice reference management apps out there with desktop and web versions: Mendeley and Zotero. Zotero is apparently the original open source version from which the developers of Mendeley decided to develop a more commercial version, which was eventually taken over by Elsevier. Mendeley is the more polished, functional and useful software. So… Continue reading Zotero vs Mendeley

# Negative Temperatures

The thermodynamic concept of temperature is defined by the following equation: $$T = \frac{\partial E}{\partial S}$$ where $E$ is the energy of the system and $S$ is the entropy. Now usually when the energy of a system increases or decreases it’s disorder, and hence it’s entropy, also increases or… Continue reading Negative Temperatures
