OC I’m back with several more community icons: check out Artemis (future kbin app), Urban Details, 3D Modeling and some other stuff

Honestly, I’ve been really enjoying making these, probably the most I’ve been excited to model something for months. So I exchanged some sleep for a faster turnaround :) Previous post here...

OC I designed and rendered a couple of icons for the magazines I started, and I’d like to share some behind the scenes images with y'all. I’m also open to doing a few more of these in future.

So I 3D modelled two icons (well, illustrations rather) for the communities that I created on kbin: Industrial Design and Jewelry Design. These icons are meant to reimagine kbin’s logo in a way that's relevant to each community....

If you have any interest in data visualization, consider giving @infobeautiful a follow.

Founded by British journalist & designer David McCandless, they've been posting their high quality visual explorations of information here since September.

The fedi account has been flying a bit under the radar so far - they have many tens of thousands of followers on other platforms for good reason.

I need a job!

My PhD is drawing to a close.

I'm looking for post-doc research opportunities or web/software development roles, ideally a combination, as in digital humanities research.

My previous research experience is in heritage and higher education for the arts.
My PhD was about knowledge frameworks and the affordances of digital tools and representations in research, in relation to research reuse, transparency and inclusivity.

I would love to be able to contribute more to innovative work on research and knowledge representations.

I am open to new possibilities! In particular I am interested in the possibility of becoming involved in sustainability and biodiversity-related research.

I am a full-stack web developer, and have a good deal of front-end design experience. I am open to all opportunities, particularly remote working!

I am not great at this self-promotion thing...
I will be putting a portfolio site online soon, but am happy to share a CV with anyone who is interested in the meantime.

Thanks for any boosts!

#PhysicsFactlet
A quantum simple pendulum.
The pendulum position is spread out, with opacity here being proportional to the probability that the pendulum is at that position at a given time. The average position of the quantum dynamics is the same as the classical pendulum dynamics (Ehrenfest theorem).

Technicalities: I used the Crank-Nicholson method to evolve the system in time. This is a 1D problem, and the only variable I considered was the angle, with the initial state being a Gaussian.

#QuantumMechanics #Physics #ITeachPhysics #Visualization

Schematic drawing of a simple pendulum oscillating, with its quantum version represented as a distribution of pendula with their transparency proportional to the probability to be at a certain position at any given time.

I'd like to make some maps to understand who can access a particular location by public transport.

I'm imagining specifying a small area and drawing all the public transport lines that intersect that area. Bonus points if I can filter by timetables - it's for church and Sunday timetables are a pain.

Can code something if needed but I've not worked with map data before. All ideas welcome :) tyvm!

Can shadows move faster than light?
Not really. There is nothing moving sideways, so nothing is moving faster than light (which, incidentally, mean you can't use shadows to communicate faster than light).
But the edges of the projection of the shadow can indeed appear to move arbitrarily fast.

Many dots move away radially from a centre to represent light. At a distance s small screen block part of the dots/light and move around, with the shape of the shadow following with a lag.

Magnetic hysteresis: In a ferromagnet the equilibrium configuration is with all magnetic moments aligned with each other. If we want to flip them, we need to flip all of them at the same time, which requires a stronger field than if the moments were independent, resulting in the characteristic hysteresis loop.

(Simulation done by numerically solve the Landau–Lifshitz equation with a tiny bit of noise added to speed the process up on a square grid of magnetic moment with periodic boundary conditions.)

Left: a square gray plan with a grid of short lines coming out of it. Each line represents a magnetic moment, and moves following the Landau–Lifshitz equation. An arrow on the left shows the external magnetic field, which starts from up and gradually decrease to zero and then goes negative. The lines representing the magnetic moments move only a little bit until the field is negative and strong, and then start precessing quickly, until they all flip in the new equilibrium configuration. Right: Plot of the total magnetization as a function of the external magnetic field, showing the characteristic hysteresis loop.

Does a chaotic system always behave chaotically?
Not really, as many chaotic systems have a subset of possible initial conditions that lead to a quasi-periodic motion.
As an example, below are two sets (black and orange) of 20 double pendula each, all with the same initial energy, and each group starting with very similar initial conditions.
The first group (black) spread out a little bit with time, but nearby initial conditions keeps evolving into nearby dynamics, which is typical of integrable systems.
On the other hand the pendula in the second group (orange) also starts with similar initial condition, but after a short transient evolve each very differently from each other, which is a mark of a chaotic system.

Simulation of two groups of double pendula. On the left 20 black double pendula that evolve staying very similar to each other. On the right 20 orange double pendula, whose dynamic quickly diverge from each other.

So far, I really like the (relatively) new -oriented interface for , one of my favorite libraries in .

It feels much cleaner, more logical, more compact, and there is indeed less need to go down to for many tweaks to a plot.

Documentation here: https://seaborn.pydata.org/tutorial/objects_interface.html

Code and result for a very simple bar chart example below. Quite compact and very clean.

Barplot resulting from the code shown in the first image. Six light blue bars of differing height. Most prevalent number of co-editors is 2, with 37.9 percent.

Any folks know of a library for drawing pretty-looking, clean boxes arranged in various patterns?

I am looking to make some simple images like this to demonstrate addition, subtraction, multiplication, etc.

Bonus points if it has support for some existing pedagogical framework (e.g. “ten frames”).
