[BlindMath] 3 Dimensional Graphs

Hello Sabra,

I just wanted to make a quick general comment about 3D plotting in the 
physical sciences. Often 3D plots are not particularly helpful and are 
done more for visual appeal than to convey information effectively. The 
usefulness of a 3D plot really depends on the situation.

For a really complicated 3D data set it can be impossible to make a 
useful 3D plot, and if data is sufficiently simple (for example symmetry 
around an axis or something) then looking at either a 2D slice of the 
data, or a projection of it, or a series of 2D slices can be just as 
informative.

At least this is my take on it.

For the record, I am a sighted person who just finished a graduate 
course on data analysis. I used the Python language and a number of very 
useful libraries for working with data sets including NumPy. A cool 
thing is that Python gets used a lot in industry these days. MATLAB can 
also do most of this.

Best wishes,

Brian

> You are correct. I do prefer to listen. However, I still believe that Braille is very important and I'm glad that I know it. There are some things like math and science that I need to be able to read. And if I am writing something long, I will write using a combination of braille and speech. Sometimes I like to get what I have written and read it to myself out loud, and I cannot do that without braille. I actually want to read it to myself instead of having something else read it to me. I can look for grammar and typos a lot easier. Also, if I am doing a speech or a presentation, my notes need to be in braille. I would say that I use both for different purposes and a lot of times I use a mixture of speech and braille. If something is really hard for me to understand, I might understand it better if I read and listen at the same time. Some math equations we're very hard for me to read and I had to have someone repeat the equation to me as I read it at the same time. I couldn'!
>   t read the braille, that was not the problem. These equations were just so complicated. It is pretty annoying that my phone does not have very good braille support. When I write an email on my phone as I am doing now, it can be harder. The braille screen input on my phone is also hard for me to use. However, if I were reading a novel or even a training manual, I would prefer to listen to it. When I am cooking, I prefer to listen to the recipe and follow the steps as I hear what to do. If I am socializing with someone, I would prefer to talk to them instead of write to them.

If you cannot get it to play your graph, you may have written an equation that has some sort of error in it. Also, after you put in your equation, it will not play the graph automatically. You have to press a button to get it to.
