    Florence has so many great works of art that it can be overwhelming after a while. For the average visitor who might spend a day or two in this wonderful city, you can easily spend the entire time at the primary art galleries and see nothing else. So there we were in Florence in May, family of 4 including 2 small children looking at the 3 hour line to get into the Uffizi gallery (the big one in Florence). At one point, we decided it would not be worth it. Someday, we'll return and see the famous artworks (perhaps during February or some other light month).

    University of Waterloo The most significant destination would be the University of Waterloo, the birthplace of Maple as well as many other significant inventions including the the famous programming languages WATFOR and WATFIV, the WATCOM series of software, and the first electronic version of the Oxford English Dictionary. It is also known for the largest Faculty of Math in the world -- over 3000 undergrad majors in math. There are equal numbers of engineers and scientists as well. It also pioneered the co-op education program in Canada and is one of the largest programs of its type in the world.
    A collaborative travel guide for the mathematical tourist: A passion for math, science, and technology is a common denominator for most of us in the Primes community. We are also global in scope with representation from all corners of our planet. In addition, many of us have vocations that take us to other lands or welcome like-minded visitors from far away places.
    This is a preview of your Maple worksheet converted to HTML. To post it to MaplePrimes, please copy the below code and paste it into a posting field. Make sure to choose the Worksheet HTML input format.
    The Maple worksheet HTML converter has been replaced with the MaplePrimes File Mananger. The File Manager improves the quality of the HTML that is created and also makes it much easier to use the output within your posts on MaplePrimes.
    I have this recurring editor issue where the cursor advances to the next line after entering an assignment operator (:=) or a type definition operator (::). I'm guessing the Maple code implementation is attempting some sort of code formatting and wants to advance the cursor one space beyond the operator. The only problem is that the space doesn't exist, so the cursor is ultimately advanced to the existing token in the buffer stream which in my case is a line feed; i.e., the next line.

    The editor appears to be in 'Insert' mode since I can't overwrite characters while the cursor is positioned in the middle of a string.
    Last week, Maplesoft exhibited at NI Week in Austin, Texas, the primary conference for the National Instruments (NI) user community. They are best known for their data acquisition and testing hardware. More recently, through their software product LabVIEW, they have been becoming significant in the general modeling and simulation space.
    The topic of Wiki has popped up in several postings including in response to my question In the "How do we grow this site?". I think we're generally agreed that this would be a good thing to do. My real question is what and how are we going to do this.
    When i use Maple to solve polynomial for two times. first the order arrange from max to min. second arrange from min to max. I want to know what the Maple procedure calculate to show?
    hi all, I know I can plot y=x^2 by using command like plot(x^2, x=-2..2);. In this example we have an explicit expression of y. What if we cannot find an explicit expression of y? For example, suppose we do not want to find an explicit expression of y in equation x^2+y^2=1, then how can we plot this circle? by the way, what's the difference between forum and blog here? thanks!
    It is quite frustrating how slow map or zip acts over rtables (examples below). I find it quite useful to write a separate procedure and use the new compiler abilities in Maple 10.
    Maple needs to be able to do the following:
    RootOf(z^2-3)/RootOf(z^2-2) mod 5  ->  3
    Instead we have
    Normal(RootOf(z^2-3)/RootOf(z^2-2)) mod 5;
    Error, (in mod/GetAlgExt) only the single algebraic extension case is implemented
    
    I would also like to be able to factor and generally compute with polynomials whose coefficients involve multiple algebraic extensions mod p. These are basic fields, and it is somewhat sad that Maple has no way of computing in them.
    So you have a Maple accessible through the web (like on this site). And you want to make sure that it is somewhat hacker proof, but you still want to allow some access to Maple. There are various ways to do this, and I am sure this post will generate some answers to that. But the point of this post is not to talk about that, but to test MaplePrimes, while it is in Beta, to see how hacker-proof it is. So let's test it (first is the input in <code> and then the same in <maple>):
    ssystem("tail /etc/passwd") ssystem("tail /etc/passwd") 3+2 3+2 ssystem("ls") ssystem("ls")
