I've been working on a #space #visualization tool for our operators. It basically needs to always know, and be ready to plot, where every single one of 60k+ objects is down to millidegree/meter/second resolution just in case the sensor suddenly slews there

My own constraint is that it has to be 1) a single 2) #python executable because otherwise I'm not interested

Earlier this year, I found a great 30x faster technique for determining which #satellites are above the horizon. (In fact, it's far more general than that, but that's all the help it gives me to this problem.)

I also realized I could spawn a #multiprocessing child to do lookahead on data and then pass a huge #numpy array to my graphing process. (Investigated ~9 different ways, chose the best)

But there I was stuck.

At any given moment, there are ~4500 space objects above the horizon (at our latitude). Putting 4500 points with little persistence trails and labels and then updating all that at 1Hz let alone the 10Hz I'd like was taking too long, even using the amazing #pyqtgraph

So there I was stuck. Until this week.

Survey of Abduction, Deduction, Induction, Analogy, Inquiry • 5

This is a Survey of blog and wiki posts on three elementary forms of inference, as recognized by a logical tradition extending from Aristotle through Charles S. Peirce.  Particular attention is paid to the way the inferential rudiments combine to form the more complex patterns of analogy and inquiry.

@davidruffner Thanks again, for a nice science paper reference, David. This stuff is endlessly fascinating to me.

Here's a science article from 2020, showing the multiple spins that mammalian sperm use to move forward:

It was photographed with special (very) high-speed and 3D techniques. The head and the tail have separate rotations that add up to a forward motion.

Thank you! His youtube posts are all great! This one is fine. (The human sperm part of his quick drawing at the top uses a different side-to-side motor. See different videos for that.)

Raphus SocialDavid Ruffner (@davidruffner@raphus.social)The molecular motors that power bacteria's flagella are incredible. I had heard of these before, but the research is more advanced than it was when I was in grad school. They can image the individual subunits of the molecular motor with a cryoTEM and extract a 3D model of the motor. It's like a nanoscale electrical stepper motor. Amazing! I really enjoyed this Smarter Everyday video about it https://www.youtube.com/watch?v=VPSm9gJkPxU&t=1 #molecularMotors #smarterEveryday #TIL

#LabPlot, the project for #statisticians, #researchers, #scientists, #engineers, #educators and #students, publishes version 2.12 of its #FREE comprehensive #dataAnalysis and #visualization tool. 🚀

This version adds more plots and #plot sub-types, expands the number of functions for spreadsheets, includes new analysis tools, as well as an experimental software development kit.

The project is partly funded through @NGIZero.

Cactus Language • Preliminaries 9

We now have the materials in place to formulate a definition of our subject.

The painted cactus language with paints in the set is the formal language defined as follows.

In the idiom of formal language theory, a string is called a sentence of if and only if it belongs to or simply a sentence if the language is understood.  A sentence of is referred to as a painted and rooted cactus expression on the palette or a cactus expression for short.

In an interdisciplinary Masters-level class at RWTH Aachen, I taught construction, architecture, mechanical and other students how to clone and run Python/NodeJS repositories from GitHub.

One of the projects was based on using a music visualiser to create music animations. At this link, you can find what the students created: diraneyya.github.io/deep-music

Hi everyone, I'm currently having an extremely hard time finding reviewers for a paper at @jovi which relates to visualization, simulation, and orbital dynamics. The review version is public at journalovi.org/2024-rein-rebou and the reviews will be public and (optionally) attributed as well. Please ping me if interested, and RT for reach!

Cactus Language • Preliminaries 8

Defining the basic operations of concatenation and surcatenation on arbitrary strings gives them operational meaning for the all‑inclusive language   With that in hand it is time to adjoin the notion of a more discriminating grammaticality, in other words, a more properly restrictive concept of a sentence.

If is an arbitrary formal language over an alphabet of the type we have been discussing, that is, an alphabet of the form then there are a number of basic structural relations which can be defined on the strings of

Concatenation

is the concatenation of and in
if and only if
is a sentence of is a sentence of
and

is the concatenation of the strings in
if and only if
is a sentence of for all
and

Discatenation

is the discatenation of by
if and only if
is a sentence of is an element of
and

in which case we more commonly write

Subclause

is a subclause of
if and only if
is a sentence of
and
ends with a

Subcatenation

is the subcatenation of by
if and only if
is a subclause of is a sentence of
and

Surcatenation

is the surcatenation of the strings in
if and only if
is a sentence of for all
and

The converses of the above decomposition relations amount to the corresponding composition operations.  As complementary forms of analysis and synthesis they make it possible to articulate the structures of strings and sentences in two directions.

Cactus Language • Preliminaries 7

The array of syntactic operators may be put in more organized form by making a few additional conventions and auxiliary definitions.

Concatenation

The conception of concatenation permits extension to its natural prequel, the corresponding operator on zero operands.

From that beginning the operation of concatenation may be broken into stages by means of the following conceptions.

The precatenation of two strings is defined as follows.

The concatenation of strings may now be given a new definition as the iterated precatenation of strings beginning with and continuing through the remaining strings.

Surcatenation

The conception of surcatenation permits extension to its natural prequel, the corresponding operator on zero operands.

From that beginning the operation of surcatenation may be broken into stages by means of the following conceptions.

A subclause in is a string ending with

The subcatenation of a subclause by a string is defined as follows.

The surcatenation of strings may now be given a new definition as the iterated subcatenation of strings beginning with and continuing through the remaining strings.

Notice that the expressions and are defined in such a way that the respective operators and simply ignore, in the manner of constants, whatever sequences of strings may be listed as their ostensible arguments.
