Saying your name
When you introduce yourself, don’t through your name out a mumbled string of syllables. It is difficult for those whose culture is not the same as yours to catch your first and last name (or others). Say: My name is (short pause) <firstname> (one second pause) <lastname>. It will be more memorable for everyone. I…

Co-authorship policy
Co-authorship and acknowledgement are forms of recognition for direct contributions to a work. I want to elaborate on the policy I follow, influenced by the groups were I have worked. I essentially agree with this blog post, which is well-written: https://ramblingsofanecologa.wordpress.com/2020/11/10/who-should-be-a-co-author-rules-and-etiquette-of-academic-authorship/ There are multiple aspects of how to contribute to a paper: “conceiving the idea,…

Understanding exponentials: COVID19 and climate change
Exponential growth is unintuitive. The default heuristics of our brains is that things will continue as they are, or keep growing linearly. In the most intense phases of COVID19, exponential growth of case numbers, and thus hospitalizations, and the trigger-happy reaction needed to stop this exponential growth curve early was understood by most people. In…

Conflicts: my rule of thumb
Conflicts are common place when working in scientific collaborations, and with people in general, whether in private or professional settings. Be it, that others take undue credit, screw someone’s plans over, belittle contributions, are confrontational and rude, or mock someone. Conflicts are stressful. Disappointment, anger, frustration, fear, insecurity, are intense emotions that can arise. My…

Urgency is the mindkiller
A senior colleague of mine once said (paraphrasing): “We can all manage to fill our week with things to do. It is not difficult to be busy. The challenge is to actively and consciously steer what you decide to spend our time on, and prioritize things that will have an impact.” When you look back…

A lesson for mastering sports
I have learned one lesson in one sport, which I have found to be universally applicable to most other sports. The lesson is as follows: Imagine your shoulder points and your hips forming a rectangle. This rectangle needs to be mobile. Start any action by moving that rectangle. Not flailing the arms and legs. Move…

How to get emotionally attached to software but leave no impact to science
How do people get emotionally attached to software? I mean positively emotionally attached to the point of plastering stickers on their laptop, or negatively attached to the level of raising their voices in discussions. Here I explore a few causes that I have seen. 1. Attachment to strict teachers This cause of attachment is common…

AGN physics open questions
How are black holes created? What is their spin distribution? What is the shape and location of the hot X-ray corona? We know it is compact (<10Rg, from microlensing) and parallel to the disc (from polarimetry). But how is it powered? In practical terms: what sets the LUV-LX relation? The relation can be reproduced with…
