Over the past couple of years, I've really fallen in love with #tikz and all of its quirks.

TikZ is a plotting/graphics package for LaTeX that is especially useful for creating mathematical diagrams.

The support for mathematical notation is unbeatable and the flexibility of the language is extremely high. Also, graphics rendered to pdf/svg in this way are extremely lightweight and reproducible.

I do find it very challenging syntax to remember though, so I put together this GitHub repository to keep track of tikz code I've written.

github.com/ctesta01/tikz-examp

Each graphic shown in the README is linked to its underlying .tex code.

Also the README has several links to documentation / tutorials that I've found helpful along with some tips I've learned from experience.

The impact #probability for #2024YR4 has been revised downward in the past days to well below 1%.

I wonder if showing how these impact probabilities change over time also helps to convince people that they should switch doors in the Monty Hall problem. 🚪🚪🐐

The analogy can be strengthened if you take into account that looking for the asteroid in a particular direction and *not* seeing it may also lower the impact probability. #PhilSci

Conference: Probability in Philosophy and Science at the University of Graz 🇦🇹, September 24-26.
It will be a long train journey, but I will speaking there; I don't think any of the other speakers are active on Mastodon.

philevents.orgProbability in Philosophy and ScienceProbabilities permeate all aspects of our lives. The beliefs we form, the various risks we assess, the epistemic uncertainty we account for, and the decisions we make typically depend on how likely we take some relevant states of the world to be. As finite subjects living in a vast world, we are constantly facing various forms of uncertainty, and it is our experiences that provide us with our most direct, though still limited, access to the world. Given the limited and perspectival character of our fundamental justifiers, i.e. our experiences, our beliefs (and the justification we have for them) seem to come in degrees. Many identify such degrees of belief, or credences, with subjective probabilities. On the other hand, it seems that probability can be interpreted in a more objective way as well. One’s subjective probability assignments may be internally consistent and yet strike us as objectively unjustified or inadequate. Accordingly, some aim to account for probability in epistemic terms that are less subjective than belief, linking it to evidence or justification. Finally, and perhaps most widely assumed, there is the view that probability is a feature of the world itself: probabilities are completely independent from any subject but are out there in the world. This view seems to align well with certain branches of science such as statistics or quantum mechanics. Of course, we can also be pluralists about probability, allowing for both subjective and objective forms of probabilities. However, despite this widespread and apparently intuitive distinction, the details of this overall picture still remain widely debated. What is more, the role probability plays in science remains strongly contested. For instance, quantum mechanics is one of the most fundamental scientific theories, but it is far from clear how we are supposed to interpret quantum probabilities. For some, they are prime examples of objective probabilities; others advocate a thoroughly subjective interpretation. On top of that, various researchers working on reconstructing quantum theory from information-theoretic principles have come to the conclusion that quantum theory fundamentally is a theory of probability. This conference has three interrelated aims: to 1) interrogate the nature and epistemological implications of probability, 2) address the role of probability in science, and 3) assess the epistemic, formal, and pragmatic norms governing our probability assignments. Issues we wish to discuss include, but are not limited to: - the nature of probability; - pluralism about probability; - the relation between probability and concepts such as belief, experience, and justification; - the constraints on rational probability assignments; - the relation between probability and reality; - phenomenological approaches to probability; - the place of probability in action; - the role that probabilities play in the sciences; - the interpretation of quantum probabilities.

A post of @11011110 has reminded me that (after a year and a half lurking here) it's never too late for me to toot and pin an intro here.

I am a Canadian mathematician in the Netherlands, and I have been based at the University of Amsterdam since 2022. I also have some rich and longstanding ties to the UK, France, and Japan.

My interests are somewhere in the nexus of Combinatorics, Probability, and Algorithms. Specifically, I like graph colouring, random graphs, and probabilistic/extremal combinatorics. I have an appreciation for randomised algorithms, graph structure theory, and discrete geometry.

Around 2020, I began taking a more active role in the community, especially in efforts towards improved fairness and openness in science. I am proud to be part of a team that founded the journal, Innovations in Graph Theory (igt.centre-mersenne.org/), that launched in 2023. (That is probably the main reason I joined mathstodon!) I have also been a coordinator since 2020 of the informal research network, A Sparse (Graphs) Coalition (sparse-graphs.mimuw.edu.pl/), devoted to online collaborative workshops. In 2024, I helped spearhead the MathOA Diamond Open Access Stimulus Fund (mathoa.org/diamond-open-access).

Until now, my posts have mostly been about scientific publishing and combinatorics.
