On some Linux distributions, the default font (Lucida Bright at size 12) for text mode in Maple's Standard GUI doesn't look as good as it might at the default magnification.

Here's a screenshot of Maple 12 and some text in a worksheet (on my very old Fedora Core 2).

Notice how some letters look odd. The "i" and "s" are mismatched, as are the "u" and "c", etc. The screenshot may not do full justice to its ugliness. That is with Maple's option for font antialiasing enabled (though it wasn't improved by disabling the antialiasing -- those letters' sizes were still mismatched).

This is with Lucida Bright, which as I gather is the "recommended" font for a Java application that is intended as cross-platform. That is used at size 12 as Maple's default style for text mode (on Linux).

So I installed the "Microsoft TrueType core fonts", by following the instructions here.

My old Linux FC2 X server can handle TrueType fonts, as I believe  most  modern  Linux distributions can.

Now I get the following look, first with and then without font antialiasing enabled. It is much improved.

I don't know how the default appearance on other, more modern Linux distributions looks. Perhaps the Lucida Bright 12pt font appears more pleasing on new distributions using the stock fonts. Feedback is welcome.

The rightmost column on this page, entitled "Points from all posts", has all zeroes.

Also, the description says that there are five classifications in the table. But there are only four.

Over the past few months, a team of dedicated staff has been working hard on a project that has recently come to fruition: I’d like to introduce you to Maplesoft’s new and improved Application Center. The Application Center provides one central place where you can find “thousands of free applications from the Maplesoft community”, such as Maple documents, graphics, animations, and packages; and MapleSim models, components, and templates.

Define the following bump function: f:=(x,a,b)->piecewise(x

RSA Algorithm Worksheet and Video Tutorial

Hi! The following worksheet illustrates how you can use determinants in a variety of geometric applications. The worksheet outlines how you can determine the area of a triangle or a parallelogram, and the volume of a tetrahedron or parallelepiped using a determinant containing the coordinates of vertices. The worksheet also shows you how to obtain the equation of a plane through three points, and to determine if three points are collinear, or four poin

Hi there! The following worksheet contains 3 examples that show you how to solve a linear system. The 3 examples outline linear systems that have solution sets containing 1 point, infinitely many points, or no points. Given a set of equations, the worksheet demonstrates how Maple can be used to convert these equations into a matrix, how to row-reduce the matrix, and how to determine the solution of the system. Then using Maple's Linear System Plot Tuto

A prolonged winter is one of the challenges of living where I do. But each year, we also get the pleasure of experiencing the very first spring day and that’s a special feeling that I would not trade for all the tropical weather in the world. For me, spring in my town is not defined by the temperature or amount of sunshine. It’s defined, oddly enough, by robots … the third week in March is typically the week of the FIRST Robotics Waterloo Regional Tournament. FIRST stands for “For Inspiration and Reward of Science and Technology”. It is an international team sport where high-schools from around the world compete in complex robotic games with full sized remote controlled and autonomous robots on the playing field about the size of half a basketball court.

I am using the Physics package of Maple 12 to do some research. The main objects I am using are spacetime tensors. However it seems the Simplify command need to be improved. Here are some limitations of this command:

I am trying to manipulate some equations of motion in block matrix form. My first attempt is with the old linalg package because I don't want the submatrices to expand until I am ready However, linalg is not working as I expected. In particular, the formation of EoM1 in the eample below does not lead the &* operator propagating into a block matrix multiplication. If there is a better way to do this with the Linear Algebra package, I would sure like to see an example. Failing that, what am I doing wrong in the linalg example?

Maplesoft has launched our brand new Application Center.  Aside from updating the overall look of the Application Center, several new features have been added, such as the ability to post comments on apps.  When you have a minute, head on over and take a look for yourself!

As I was preparing for an upcoming presentation, I stumbled on a graphic that I always thought was one of the best ones in my endless collection of Powerpoint slides. This particular graphic portrays the evolution of engineering modeling software and I always thought it was an incredibly impactful and clear view on a very complex topic. Unfortunately, I really can’t take any credit for it. The basic concept was created by Mr. Alex Ohata of Toyota. I remember the first time I saw it at a conference.  It really was one of those light-bulb moments where the Universe unfolded as it should … and now I pay due homage to this work of scientific art.
