As you may have already heard, in order accelerate the growth of our different product lines, Maplesoft decided to spin off our online education products into a separate company. Let me introduce you to DigitalEd.

DigitalEd will focus on online education technology, including online courseware, testing and assessment, and placement testing (i.e. Möbus, Maple T.A., and the Maple T.A. MAA Placement Test Suite). Maplesoft will continue to develop and support Maple, MapleSim, and their related products, for both academic and professional use.  The two companies will maintain close ties, and Maple will continue to supply the mathematical engine to the DigitalEd product line.

For more information about this change, see https://www.maplesoft.com/digitaled/

For the past two years the Queen’s College of Guyana Alumni Association (NY) has been hosting its Queen’s College Summer Maths Institute, and Maplesoft has supported this initiative by giving students access to Maple.   With Dr. Terrence Blackman at its helm, the institute aims to sustainably implement a developmentally appropriate and culturally resonant middle school learning environment that engages Guyanese students in a cognitively rich mathematics learning experience.  The experience is intended to place them securely on pathways to STEM (Science, Technology, Engineering and Math) excellence.

The program uses a developmentally appropriate approach that combines significant mathematical content with a setting that encourages a sense of discovery and excitement about math through problem solving and exploration. Program Manager Shindy Johnson, a former student of Queens College, noted that by the end of the first week math sceptics fall in love and gained confidence, and math lovers renew their passion.

As avid Maple users, Dr. Terence Blackman and Cleveland Waddell, one of the main organizers and lecturer,  give the students the opportunity to use Maple. Last year, the students were amazed by Maple's computational power. “It was nothing like they have seen before.  Many students also wrote their first lines of computer code using Maple during the summer camp.  Maple is an invaluable resource for us during the camp,” said Waddell.

Students receive further enrichment through field trips to broaden their appreciation for education and industry in Guyana.  In addition, Guyanese professionals visit the Institute to share their expertise, career journeys and practical applications of math and other STEM disciplines in their professions.

Students who participate ranged from self-professed math lovers to teens who confessed to fearing and even loathing math. By the end of the first week, math lovers had discovered even greater “beauty in the mathematics” and those who quaked at the thought of math were beginning to commit – with confidence – to improving their math grades. This year’s Queen’s College Summer Maths Institute will take place July 26-August 3, 2018 in Georgetown, Guyana.   

Recently I looked through an interesting book D. Wells "The Penquin book of Curious and Interesting Geometry" and came across this result, which I did not know about before: starting with a given quadrilateral , construct a square on each side. Van Aubel's theorem states that the two line segments between the centers of opposite squares are of equal lengths and are at right angles to one another. See the picture below:

It is interesting that this is true not only for a convex quadrilateral, but for arbitrary one and even self-intersecting one. This post is devoted to proving this result in Maple. The proof was very short and simple. Note that the coordinates of points are given not by lists, but by vectors. This is convenient when using  LinearAlgebra:-DotProduct  and  LinearAlgebra:-Norm  commands.

The code of the proof (the notation of the points on the picture coincide with their names in the code):

restart;
with(LinearAlgebra):
assign(seq(P||i=<x[i],y[i]>, i=1..4)):
P||5:=P||1:
assign(seq(Q||i=(P||i+P||(i+1))/2+<0,1; -1,0>.(P||(i+1)-P||i)/2, i=1..4)):
expand(DotProduct((Q||3-Q||1),(Q||4-Q||2), conjugate=false));
is(Norm(Q||3-Q||1, 2)=Norm(Q||4-Q||2, 2));

The output:

                                                      0
                                                    true

I just feel that if at least one person less experienced than me reads this it will be a worth while post, because it will help them avoid things that eluded me when I was younger.

Up to swMATH   Maple is referenced in 4183 articles   in zbMATH   and

up to swMATH Mathematica is referenced in 4654 articles  in zbMATH.

These numbers are sure unexpected to me. I think the ratio of the prices of academic editions MMA/Maple (which approximately equals 2 ) truly reflects their capabilities.

It post can be called a continuation of the theme “Determination of the angles of the manipulator with the help of its mathematical model. Inverse  problem”.
Consider  the use of manipulators as multi-axis CNC machines.
Three-link manipulator with 5 degrees of freedom. In these examples  one of the restrictions on the movement of the manipulator links is that the position of the last link coincides with the normal to the surface along the entire trajectory of the working point movement.
That is, we, as it were, mathematically transform a system with many degrees of freedom to an analog of a lever mechanism with one degree of freedom, so that we can do the necessary work in a convenient to us way.
It seems that this approach is fully applicable directly to multi-axis CNC machines.

(In the texts of the programs, the normalization is carried out with respect to the coordinates of the last point, in order that the lengths of the integration interval coincide with the path length.)

Due to the mechanistic process of our students and little creativity in analysis in schools and universities to be professionally trained is that STEM education appears (science, technology, engineering and mathematics) is a new model that is being considered in other countries and with very slow step in our city. In this work the methods with STEM will be visualized but using computational tools provided by Maplesoft which is a company that leads online education for adolescents and adults in the current market.

Using Maple's native syntax, we can calculate the components of acceleration. That is, the tangent and normal scalar component with its respective units of measure. Now the difficult calculations were in the past because with Maple we solved it and we concentrated on the interpretation of the results for engineering. In spanish.

Last week, my colleague Erik Postma and I had the pleasure of spending a few hours with a group of bright and motivated high school students at the Math for Real: High School Math Solves Real Problems workshop held at the Fields Institute for Research in Mathematical Sciences in Toronto, and sponsored by the Fields Institute and NSERC PromoScience. The purpose of this three-day workshop was to train students for the International Mathematical Modeling Challenge, also known as IM²C.

The IM²C is hosted by York University and run by the IM²C-Canada committee, consisting of parents and high school teachers, as well as faculty and students in York’s Department of Mathematics and Statistics. In this competition, students working in small teams have five days to solve a mathematical modelling problem in diverse application areas. To support the “Real World” aspect of the contest, students are expected not just to showcase their mathematical creativity and problem-solving skills, but they are also asked to clearly communicate their analyses and conclusions through a written report and visualizations.

The contest allows students to use appropriate software tools to help them with their tasks. Of course I am biased but I can’t help thinking that Maple is the perfect tool for students wanting to do a combination of prototyping, modelling, visualization and document-preparation. The IM²C organizers also thought that the students could benefit from our software, so Erik gave an hour-long introduction to Maple. I was impressed by the students’ enthusiastic remarks and sometimes challenging questions, though admittedly they were partly motivated by the chance to receive as prizes our highly coveted limited-quantity “Math Matters” t-shirts.

The workshop also introduced the students to other software products, taught modelling and writing skills, and had them work on fun practice problems. Over the lunch break, I was struck by the sense of camaraderie at this event, which probably should not have surprised me, as unlike many other competitions involving mathematics, this one is a true team-based activity. Both Erik and I are eager to see what the students will be doing with Maple. Responding to the students’ enthusiasm and interest, Maplesoft has agreed to offer complimentary Maple licenses to all students participating in IM²C. 

As a Corporate Affiliate of the Fields Institute, Maplesoft is pleased to provide training and support to students and researchers that come to Fields for its many events. Developers like myself are encouraged to participate in the institute’s events when possible, and I’ve had the opportunity to attend a number of workshops in the past few years. I encourage you to look at their wide range of activities and to consider visiting the culturally diverse city of Toronto!

The first update to the Maple 2018 Physics, Differential Equations and Mathematical Functions packages is available. As has been the case since 2013, this update contains fixes, enhancements to existing functionality, and new developments in the three areas. 

The webpage for these updates will continue being the Maplesoft R&D Physics webpage. Starting with Maple 2018, however, this update is also available from the MapleCloud.

To install the update: open Maple and click the Cloud icon (upper-right corner), select "Packages" and search for "Physics Updates". Then, in the corresponding "Actions" column, click the third icon (install pop-up).

NOTE May/1: the "Updates" icon of the MapleCloud toolbar (that opens when you click the upper-right icon within a Maple document / worksheet), now works fine, after having installed the Physics Updates version 32 or higher.

These first updates include:

• New Physics functionality regarding Tensor Products of Quantum States; and Coherent States.
• Updates to pdsolve regarding PDE & Boundary Conditions (exact solutions);
• A change in notation: d_(x), the differential of a coordinate in the Physics package, is now displayed as shown in this Mapleprimes post.
