Monday's session in our Exploring and Getting Started with Wolfram Language Daily Study Group will feature a guided tour of the new Wolfram Notebook Assistant with @Arben Kalziqi. He'll show how to get help writing code, running calculations and getting answers to questions that include real-world data from the Wolfram Knowledgebase, all from a chat-based assistant. Looking forward to it!

Hello, happy to hear you've passed the quiz. We will be collecting the passing attendee emails and sending out the certificates next week. Please let us know if you do not receive your certificate.

Have a great weekend!

Hi Arben,

I missed the end of Tuesday's recording since I had to hop on another meeting. I just watched it and noticed that you discussed how to make visualizations with sliders. Can I make a visualization and post it somewhere for my students to play with it? The code worked on Wolfram Alpha, but it did not activate the slider. My students technically have free Mathematica as well, but it's not a language they'd be familiar with. If I can do something like Desmos/GeoGebra applets for them, it would work great and would not require downloading or working with the commands directly.

Another question related to Tuesday's topic is about the parts in lists and MatrixForm. I'm a bit confused about how those work. If I have an odd number layers, such as a 4x3x2 list, MatrixForm turns it into a 4x3 matrix of size 2 vectors, and not a row of four 3x2 matrices. I experimented with a five layer list (4x3x2x2x3) and that also turned into a 4x3 matrix of 2x2 matrix of size 3 vectors. It looks like the last layer always becomes the innermost vector size in the matrices if we have odd number layers. Is that the default? Can that be changed?

Relatedly, it looks like there are no parts to the MatrixForm version of a list. If I look at part 1 of a list, I get the first term. But once I convert it to a MatrixForm, then part 1 gives the whole thing, which means the MatrixForm is a single part type. I don't get the first entry in the first row. In other words, the MatrixForm doesn't think of its entries as parts. I don't have access to Mathematica Notebook Assistant, but another assistant said it's because the MatrixForm is only for displaying and does not convert the list to a matrix. Is that correct?

Thanks for any information!

Hi,

Could you ask BigMarker to permit downloads of the study group recordings, assuming that functionality exists in BigMarker? It's a matter of convenience (and user-friendliness) since it's possible to record anything that appears in a GUI desktop using an external program.

Thanks.
