Quaternions are essentially magic. With just four numbers, they can describe the position and orientation of an object in space. For example, the rotation of an object about one axis. Consecutive rotations can also be described by a quaternion. There are many explainer articles which help to understand quaternions and their uses (they are used […]
Calendar: Assessing Raspberry Pi Camera Uptime
A while ago, I set up a couple of Raspberry Pi Zero cameras to make long-term time lapse movies. To recap: the idea was to take pictures every ten minutes and turn them into a movie. The process is totally automated so that every day, the photos from each Pi get saved to a server, […]
Notes from a panel II: Value of successful BBSRC grants
This post follows on from the last post on BBSRC Responsive Mode funding. Another frequent question from applicants is: “How much can I ask for?” One answer is: the same amount as successful grants. This information is freely available and can be downloaded from the UKRI website. All awarded grants can be searched (even those […]

This month I spent a lot of time evaluating proposals for BBSRC Committee D. At the same time a number of my colleagues were also preparing BBSRC applications for the next round. A question came up: Is it best to put Track Record before Case For Support or vice versa? If you have no idea […]

Child’s Play: pi-hole set up for a safer internet
I have been running a pi-hole to block ads on my home network for a while. It’s great! Not only are ads blocked, but it speeds up internet browsing because… the ads do not load. I wondered if it would be possible to use a pi-hole to make a child-safe internet experience to protect the […]
Coming Soon: The Digital Cell
Long-time readers might remember the short-lived series on quantixed called The Digital Cell. There is a reason why I stopped these posts, which I can now reveal… The Digital Cell will soon be a book! Published by Cold Spring Harbor Laboratory Press, The Digital Cell is a handbook to help cell and developmental biologists get to […]
Communication Breakdown
There is an entertaining rumour going around about the journal Nature Communications. When I heard it for the fourth or fifth time, I decided to check out whether there is any truth in it. The rumour goes something like this: the impact factor of Nature Communications is driven by physical sciences papers. Sometimes it is […]
Rollercoaster IV: ups and downs of Google Scholar citations
Time for an update to a previous post. For the past few years, I have been using an automated process to track citations to my lab’s work on Google Scholar (details of how to set this up are at the end of this post). Due to the nature of how Google Scholar tracks citations, it […]
Turn A Square: generative aRt
A while back I visited Artistes & Robots in Paris. Part of the exhibition was on the origins of computer-based art. Nowadays this is referred to as generative art, where computers generate artwork according to rules specified by the programmer. I wanted to emulate some of the early generative artwork I saw there, using R. Some […]
