Hi WIlliam:
I'm curious, is there any further progress on this plan of a Use Sage!

Ah! Linear Algebra! This creates an itch I have to scratch, especially if you intend to emphasize its computer applications.
I firmly hold that modern approaches to teaching Linear Algebra are deeply crippled by failing to go far enough in their concepts. I am a huge fan of the Geometric Algebra of Dr. David Hestenes, Professor Emeritus of Mathematical physics at Arizona State University. This is to be sure based on Clifford Algebra but in a way that is vastly more user friendly, something you find too rarely in mathematics nowadays. think of defining "vector" so it is compatable with the traditional definition used in physics, an entity having direction and magnitude, representable by a string of REAL numbers. I should note that complex numbers are not permissible as components as the equation" i^2 = -1" is not unambiguous in Geometric Algebra. There are many possible entities whose square can equal -1 and they are best handled using a spinor algebra. These fundamental spinor algebras play a big role in Geometric Akgebra, especially the sopinor algebra of

As a 2008 SIMUW'er, I have to say this is an amazing program (both SIMUW
and Sage, that is)! I squarely blame SIMUW, William, and Sage for getting
me sucked into the open-source world. :-)

Is there a record of what you did with them? I'd be very interested.

Thanks,

I was lucky in that what I did was fully funded -- the students didn't have
to pay for anything, and got full room and board, thanks to a huge
anonymous donation to the program (SIMUW).

Sage Days for high schoolers?

See for instance [link] - which I will be
teasing my open source advocate friend at Bentley about :) I bet it's a
money-maker for them, anyway, at $1700 a pop for housing that wouldn't be
used in the summer anyway.
Certainly some of what William has done with HS students has been sort of

Helloooooooooooooo !!!
I have a question about the circular_planar function in the graphs package.
You are right, the problem comes from Sage : the documentation of that
method is not very clear, and in this case the result is not the one you
would expect. The code is good, but there is no way for you to guess what

Re: Coursera course on CS linear algebra using Python

Right. I guess as a "blended" course it is interesting, but I hardly
think that people who know *neither* LA *nor* any programming would be
a good candidate for this course's level of discourse. It's pretty
hard to teach two things at once.

circular_planar the graphs package

2013-04-10T19:27:43Z

I have a question about the circular_planar function in the graphs package.
The first line of the documentation says:
*Tests whether the graph is circular planar (outerplanar)*
*
*
My understanding of the outer planar property is that, for example, graphs.CircularLadderGraph(6)
would not be outer planar, but it is circular planar. Can anyone clarify

It says " You will write small programs in the programming language
Python to implement basic matrix and vector functionality and
algorithms, and use these to process real-world data..." so I'm
guessing he views the lack-of-math-functionality in Python as an
advantage for his teaching style.

Just FYI, seems relevant.

If someone knows the instructor, they should tell him to use Sage :-)
though we aren't at Python 3 yet, which it sounds like is what he'll
use.

Nice. Thanks Karl!

This is already a few years old, but I love the way the author so
naturally pulls out Sage as a resource AND makes a great pedagogical
moment with it.
