Getting a PhD, Week 9: On Passion and Talent

Coming into the research year of my Masters, I was full of uncertainty. If I was either naturally talented or highly motivated - preferably both, as it seems the scientists that surround me are - I knew that I could do it, could become a true scientist. For the previous six months or so I hadn't felt either.

Getting a PhD, Week 5: The Joy of Sextractor

I love programming. There is little more satisfying than watching your hard-written program cascade into reality. It's the closest I've ever come to feeling like a god. However, this rarely - perhaps never - happens on the first try. I present the following as an example of the numerous frustrations that can encumber scientific research.

Getting a PhD, Week 1: Indexing Starts at Zero

My name is Lachlan Marnoch, and I have just begun a PhD - the degree of a Doctor of Philosophy, an antiquated title from back when philosophy was anything that involved deep thinking about any topic. The specific flavour of thinking which I’ll be doing is on astrophysics. What that means is that I will use physics to try and make sense of information from the night sky. As with my Masters, I’ll be studying fast radio bursts - very brief, very mysterious bursts of radio waves originating from other galaxies. They’re pretty fascinating, and I’ll get to explaining more about them soon.

A Map of Every Place I've Ever Been

You could fit a linear trend to the points on this map, if you wanted, and probably get a pretty good χ2. If you follow that through logically, I must be destined to travel to northern India, Greenland, and the Antarctic Peninsula. Maybe I can go other places where the line wraps back around the Earth.

Essay: "Tens and tenths: decimalising calendar and angle"

Way back in first year, for an elective about soft mathematics (that wasn't the official description), I wrote an essay about the advantages and disadvantages of adopting further decimal units. I tidied it up a little, and here it is!

Which Nintendo characters would burn in holy water? A comprehensive study

Yesterday, Simon Belmont (of Castlevania fame) was announced for Super Smash Bros. Ultimate. One of Simon’s attacks is holy water. The only possible conclusion to is that, in some way, every character in Smash is an unholy monstrosity that must be vanquished. Here, we try to work out why.

The Ultimate* Cheat Sheet for Astrophysics Students

At some point during my undergraduate degree (Bachelor of Science in Astrophysics, with a Bachelor of Arts in Creative Writing) I thought, "wouldn't it be cool if I collected all the physics and maths formulae I've learnt into a notebook?" This became three notebooks, then, when I realised how untidy they were getting, a LaTeX document. In the hope that others might find it useful, I decided to put it up here. Three years after it began, here it is!
