Wolfram Blog: Spherical Aberration Optics Problem Finally Solved Using the Wolfram Language

posted on August 13, 2019 by Swede White

Solving a 2,000-Year-Old Mystery It’s not every day that a 2,000-year-old optics problem is solved. However, Rafael G. González-Acuña, a doctoral student at Tecnológico de Monterrey, set his sights on solving such a problem—spherical aberration in lenses. How can light rays focus on a single point, taking into account differing refraction? It was a problem [...]

Wolfram Blog: Sharing Your Creations Just Got Easier with the Wolfram Language Paclet Repository

posted on March 03, 2023 by Bradley Ashby

Since we released the Wolfram Function Repository in June 2019, we’ve often run into situations where someone wants to distribute content that can’t easily be contained in a single, standalone function. The answer is usually to create a paclet, the Wolfram Language equivalent to what would be called a package in other programing languages. Paclets […]

Now, 7 years later still nothing and I'm looking with a bit of sadness at videos like this. Other hot topics, like neural networks, have flourished in a fraction of the time, although everybody who is serious about it probably uses TensorFlow or other alternatives. So it is still not more than a playground for some fancy demos.

I have released a stable version 1.0.0 of MeshTools package. If you find this package useful, feel free give any feedback. Also, to make messing around with source code a little bit easier, the repository contains quite extensive test suite.

I'll never understand finding a question with an accepted answer and neither the question or answer has an upvote. If I take the time to answer a question then I been the question worthy of a vote. Or if someone answers my question - if the answer is on-topic I give a vote.

Practical, fast and reliable way to read CSV files (why is that we still don't have this in 2016?!?) Import is not reliable because it's trying to be too smart. And we can't specify the column types. SemanticImport is slooooow. Import should be faster too.

I feel as though I've become a bit less patient with (particularly newer) users on the SE. Maybe, probably, it's completely on me but I feel like the eternal september is even more septembery lately. (Insert Principal Skinner "it's the children who are wrong" meme)

This whole unit system is a joke. I don't even know why they added it. Every time I try working with it (out of necessity, since all the *Data functions return them), I get extremely frustrated about how unusably slow it is.

@all: I hope everyone knows that there is an easy way to turn on LaTeX for our chat. Go to your bookmarks manager and create a new bookmark called "Start LaTeX in Chat". As URL, you don't use a normal URL but you paste this code in it. Now, it is as simple as pressing this bookmark and bam, you have LaTeX turned on

To whom it may concern.
Hello, my name is Vinicius, and I need the help of Mathematica & Wolfram Language.
Last year, the users @Michael E2 and @cvgmt presented valuable suggestions and orientations that have greatly helped me with my research problems. Today, I am writing a scientific work in which I want to acknowledge these users, but I am facing difficulties in contacting them (Below, you may find the links to my posts).

Bearing this in mind, is there any way to contact these users from Mathematica & Wolfram language?

It's odd that the blog post begins with the question "So, are you using Wolfram Language and its computational intelligence in your production software system?" considering the free engine explicitly does not allow that

I have an idea but I am not 100% sure this is a good idea and I wanted to get some feedback first. I was thinking about asking the SE community what FEM features should be added next. This question is, due to my work with WRI, a bit different than other questions here, I understand that. I have a draft text that I can post if people here are not completely opposed to the idea.

But being accused of introducing a bug "so bad that someone must have worked at making it bad" as an accomplice to "an intentional, hidden part of Wolfram’s strategy"? That hits home a bit. In my life, I've been wrong, I've been stupid (there seems to be no end of that!), but I try very hard to be honest.

fyi, Mathematica 12.0 did a very good job in the Kamke differential equations test suite. Mathematica score improved from 77.47% in version 11.3 to 82.78% in version 12. Also its speed improved quite a bit. From average of 26 second to 1.75 seconds per ODE, which is excellent speed improvement.

They seem to have changed the user profile today. Now the "last seen" time is gone (again, I think). I used that to give someone a fair chance at responding to an inquiry before closing/voting. I guess now I have to assume they've been unresponsive. It's a waste of a close vote when a problem can be and in fact is easily fixed with an edit by the OP. Not to mention that it risks closure, non-reopening, and alienation of a user.

Matlab's GUI uses event call back. And I did much more complicated GUI in Matlab's actually than in Mathematica, and never had a case where I did not understand why something is working or not working the way it was. It was much easier to understand the flow. Not with Dynamics where things are more fuzzy. One day, I might learn Qt and C++ and try that.

The longest gap in time between major releases have been V 3.0, which happened almost 6 years after version 2.0

Nasser

Jan 23, 2023 20:06

@Marteen from this page we see there was about 6 months between 13.0, 13.1, 13.2. So if 13.3 will happen, my guess it will be around June. It is possible also for WRI to just make 14.0 release and my guess this will happen in the fall if so as the average time between Major releases have been around 2.5 years in recent times.

nice example why adding symbolic on top of a language which is not symbolic to start with will produce something less ideal to work with. differentiating-a-bessel-function-with-lambda You need to use sympy's symbolic besseli function rather than scipy's numeric jv function This problem is not only in sympy, but with Matlab's symbolic toolbox, and Julia symbolics and to some extent sagemath...
