I just joined and am technically inclined but have a real software disability. I have just spent a couple of hours in extreme aggravation. I would just like to plot a curve and I get millions of pages of instructions and details of my options but nowhere I can find does it tell me how to get to a page where I can actually get it to do something. I go to the help line and they just ask ME questions and make me wwait, then tell me to send an email somewhere else. I understand the plot function how do I get to a place where I can actually do it?

Hi, I am Martin. I am a health economist in the Centre for Health Economics at the University of York. These days I mostly work on data and I use R and Stata. I have previously worked on economic theory and for that, at various times, I used Mathematica -- the last time about 15 years ago(!) . I am getting back into some theoretical work now, studying optimal incentive contracts and so picking Mathematica back up. I am very rusty with it. I very much appreciate the structure of Mathematica .... everything is an 'Expression' .... very neat and very unified. I know a bit more maths now than I did 15 years ago (I did an Open University maths degree in my spare time) and so like understanding a bit more of what is under the skin of this program. Wish I had had access to it whilst doing an introduction to Group Theory; I could have more successfully cheated on the assignments!

I have used Mma since about 1998 when I found it as part of my computer science studies at the Chalmers University of Technology in Gothenburg. It first became my main, and later, as a became lazier, my only tool for computation-related problem solving. I have worked mainly in the social sciences and humanities in Sweden, with various kinds of more or less complicated data analysis and visualization.

For some years I worked as a "product expert" for the Swedish resellers of Mma, with information, courses and some development. I have also tried to introduce Mma in Swedish secondary education, with very little success.

Since January I work in an area called "digital humanities" and I am curious to see how Mathematica will measure up to the many other programming languages and tools in use there. It seems to me that Mma should do quite well, with its functionality for manipulation of strings and lists, not the least in combination with interactivity.

I have a specific question too, if perhaps someone reading this is an expert programmer. :) An interesting idea in digital humanities (DH) is to search large sets of text for common subsequences of words. Each text can consist of say 100 000 words, and the set can contain, say, 1000 texts. The problem is similar to that of sequence alignment in genomics, but also somewhat different. As a test I have used SequenceAlignment function on smaller texts, but it is not clear to me if it is possible to adjust its functionality for the "real" task. Help.

Hello, I started out as a child, albeit a bright, troubled, talkative one unable to concentrate. I went to High School in the 60's, graduated into a hospital with severe depression and continued confusion. After some flight training and taking a number of exams I was offered entrance into the Air Force with immediate promotion and then declared 4-F. I went to college on the GI bill and spent 4 years failing miserably. I stumbled through life for a while and eventually landed a steady position as a guest of the Dutch Queen on a small island off the coast of Venezuela. My four year education began in earnest here, receiving crates of books and competing with the local fauna to see who could devour them first. After graduation I took a contract job in the Electrical Engineering department of a large utility assisting engineers doing studies and modeling their systems. They found that I needed no assistance from the engineers and kept me on. After a dozen peaceful, happy years I moved on, doing odd jobs. I worked in agribusiness and then doing bioinformatics for a drug discovery company, chiefly designing very large databases for the storage and retrieval of the exponentially increasing volume of biological sequence and annotative data for sequence analysis and data mining molecular data for drug candidates. I ended the first decade of the millennium moving a bank (qua data), part of a single bank purchase the price of which, by the time I arrived, would have bought a dozen of the world's largest banks. I have retired now, am taking some classes and doing some short-term consulting.

Hi Eric, Your project sounds very interesting. If you have not all ready, you might investigate Amazon Web Services (AWS) for your project.

My name is Joris Verrips, I make speaking software for the handicapped and do research in that area. Videos are on my website

I use Mathematica to make sense of the data from research, mostly Plot but also BarChart, FindFit, Location and related functions. Some days I try my hand at recreational programming, and I have attended a few courses at CAN, the Netherlands. This helped to understand how Mathematica operates internally and how the Evaluate and lambda functions fit in. It was very useful to me personally and was even necessary to see Mathematica is not as unpredictable as it seemed at first.

Very slowly I proceed to understand the Symbolic programming paradigm and I start to really like it. Took me a long while because I do not like details and tend to read and forget the manual. Also took me a while to accept how much the Plot command can do.

I would like to integrate my speaking software with Wolfram technologies, especially semantics, hope to meet some people with similar interests and even consider if I should not port all my speaking software, to distribute at low cost and get more feedback.

Also I wonder if and how Mathematica and related matters should be taught. It contradicts accepted wisdom like languages should be small, universal programming languages are impossible, and must be impossibly complex too. Also it uses Math for notation, amazingly, it is not fully object oriented and mixes high-level design with low-level details and extremely pluriform syntax. But it is much fun and it is very fascinating as well and rather helpful in my research and might well be better suited to math-inclined highschool students than the TI 82.

In the Appendix I have included an example of my recreational programming that aimed to reproduce some wall paper that I saw long ago and to write well documented code too. Not something I do every day, alas.

Hola Omar, greetings from a former "rolo"! I spend my time as a bachiller at the german school in Bogotá! Allow me to tell you as somebody, who now retired due to health problems is updating his mathematical skills to be able to use the technique of design by modeling for his hobby building a sailboat. I have analyzed in some level of detail competing products and have decided to embarque in using Mathematica and System Modeller, because Wolfram offers the opportunity to acquire a license for none commercial use at a reasonable price. For the other tools I would have to sign in at a german university and would only be able to use their product while being at the university.

Mathematica, specially now in release 10.0, is a powerful tool for symbolical and for numerical mathematics and to combine it by connecting it to external hardware! System Modeller and the programming language Modelica represent a powerful toolset to combine mathematics and experiments. As it is 35 years ago that I left the university my mathematical skills have eroded and also mathematics has advanced a lot. So I have embraced to charter to make my bachelor in mathematics. Mathematica is a powerful and very adequate instrument to apply the mathematics I am studying following the courses offered from the MIT for free via "OpenCourseWare" to apply that to address the mathematics to deal with problems I do formulate myself. I am also still looking for a good source to study "Modelica" to create an adequate model of a stepper motor and its controls in such a way that it reflects the functionality offered to control a stepper motor using devices from a company called "Trinamic". So bottom line: mathematica from Wolfram is a great tool and its language probably the most advanced and sophisticated for symbolical mathematics. For simulations there are more advanced tools from the 2 competitor, but together with Modelica and the improvements system Modeller will have in the next years I have decided to go with this tool!

Hi, I am Hellmut and I am refreshing and developing my math knowledge to be able to design, model, simulate and will be using Matlab and Simulink to optimize a sail control system I am developing as part of my activities as a hobby model boat builder. The boat I am developing is the red line along which I keep my grey cells active and the objective of modeling my concept for a sheet control system using a stepper requires to refresh and update my 35 years old math knowledge. With this goal i am studying in self study, using the free courses available from MIT at OpenCourseware and a few german universities to learn all courses that make up the math bachelor degree at the technical university of Munich. Once this goal has been achieved y will join that university to get the degree, just for fun. mathematica will enable me to "play" wit the math I am learning to deepen my understanding and practising to apply it! I will acquire the SystemModeler additionally to model my concept of the sheet control system I have in mind and simulate it to capture critical parameters and to optimize the parameters for best energy efficiency and to better understand the impact of design decisions! I hope God will give me enough time to follow those goals for the many years that hopefully are ahead of me!

Hello, I'm Henrick. I have a Ph.D. in Electrical Engineering from The City College Of New York. I am currently an instructor at the University Of South Florida, in the Department of Computer Science. In my previous life, when working in Industry (Bell Labs, IBM T.J. Watson Labs, UPS Research Labs, Nielsen Media Research), I specialized in Pattern Recognition. I did so in Image Processing, Image Recognition, Handwriting Recognition, Optical Character Recognition and Face Recognition. I also wrote algorithms for a Financial Start-up to analyze stocks and determine when to buy or sell equities, determining target prices and confidence levels of those predictions. I currently am still interested in all those areas, but am currently writing apps for the Windows and Windows Phone platforms using C#. I have used Net-Link to connect a C# library to work I was doing on Mathematica, with great success. I have lots of ideas and am interested in pretty much anything that involves the use of Mathematics to solve problems (pretty much everything). My interest in Mathematica is immense. I find it to be an amazing tool. However, one thing that I find disturbing, is that I find it difficult to learn. For instance, I've worked with Basic, Assembler, C, C++, C# and I can always describe in exquisite details my algorithms in those languages. Perhaps it is because each statement is a simple piece of computation. The beauty of Mathematica is that I can express in one line what would require 100's of lines in those other languages. And therein might lie the issue. Each function in Mathematica is so powerful that I have difficulty in associating a general, high-level algorithm with just a few functions in Mathematica. But I am working on it. I wish I had been introduced to it 25 years ago. Now, THAT would have been something. But, as we say in French, "Il n'est jamais trop tard pour bien faire", meaning, "It is never too late to do well". So, onwards and upwards with learning more of Mathematica.

Hi, I'm Chen, Honglong from Taiwan. I'm an R&D director in the field of electronic cooling industries. Everyday I engage in projects for designing various kinds of thermal solutions for PC coolers, heat sink, heat pipe fin modules, etc. In order to cope with these cumbersome designs, I haven't been using Mathcad for heat sink footprint estimation; then using CFD code Flotherm for further refinement; finally, we do the mockup sample for final validation. Our clients include Acer/Asus/Lenovo/HP/DELL, etc.

Recently, I work for my PhD degree and have some new projects that need to optimize the cost/weight and performance. I have begun to use Mathematica to solve heat equation / fin equation which can't be done in Mathcad. Since then, I found Mathematica much more productive and capable to meet my needs. For the time being, I use Mathematica everyday for my design works and can't leave without it. That's the most powerful math tool I've ever found!

I am a physicist by avocation although I am making my living in other ways nowadays. I am doing general relativity calculations using Mathematica just as a hobby and for the same reason I went into physics in the first place:curiosity about the universe.

I have not been able to post a question because the software is asking me to choose a "post type", which I could not even see using Chrome, and am choosing it in Firefox to no avail. So I'll just post it here in the hopes that someone could help...:

I have a 4x4 matrix which I am trying to find eigenvalues to, but much of the output is suppressed with <<n>> type output where n ranges from 1 to 5544. I tried stopping that behavior to no avail with: SetOptions[EvaluationNotebook[], OutputSizeLimit -> Infinity] $OutputSizeLimit=Infinity.

Here is my input line: ToRadicals[ Simplify[Eigenvalues[RUd], Element[{f[t], gg[x], Derivative[1][f][t], Derivative[1][gg][x], r}, Reals]]]

How do I get all my output?

Hello, my name is Scott and I'm new to the group today. I live 2 hours by car west of Seattle in the blue hole of Washington state.

I'm a retired naval officer who worked in passive submarine detection but came to it from a history/poly sci background. As such, my math background needs work and I'm doing that with Mathematica and Khan Academy. My aims are to use Mathematica for statistics and astronomy. I may branch into Arduino as well. I'm also waiting for the Wolfram language to hit the streets. Who knows where this will all go but I'm looking forward to the journey.

Hello. I'm Eon, a recent compsci grad from University of Waterloo, and I'm currently unemployed... orz.

My first encounter with Mathematica was about 10 years ago. I was preparing for a algorithm contest with my friends, and some of them were using pirated ;) Mathematica 5. I had it installed on my laptop, too, and was so amazed by the power of symbolic computation. That's when I became a fan of Mathematica, but soon I had to say good bye to it because I decided not to use any pirated software.

In my second year in university, I finially purchased a copy of Mathematica 8 home edition, and it gave me lots of power. For example, while taking lecture notes, I could solve and plot mathematical equations and systems. Also, I could rapidly build prototypes of various algorithms, ranging from 3D graphice to computational vision and AI.

I also made little music using Mathematica. All the sound samples used in the music is generated by solving Lorenz system in Mathematica, with some effects and adjustments applied from composing software.

Whether they are free or need payment I will have to make the right adjustments to acquire them, overall I want to be a member or client of Wolfram.

I can't really brag about anything great that I have done in my scientific career so far, so I will leave that out :-)  My best piece of work, made together with a few of my fellow students, was a new method developed for detecting and quantifying levels of the active compounds of Hypericum Perforatum, Hypericin, Pseudohypericin and Hyperforin in human blood plasma, by the means of an MS compatible HPLC method with UV endpoint detection.

Beside that I've spent most of my time programming. This includes programs for PCs,  and Apps for Androids and iPhones. I hope to use the community for learning more about general Mathematica skills, and surely some best practices!

Normally I'm developing software using C/C++. I think that there is a fine line between understanding an algorithm
and dealing with underlying machinery. That's why I'm using Mathematica. 

When you start to develop/explore a new algorithm you first want to understand how the algorithm does behave
and maybe later, after gaining a full understanding, deal with system specific issues such as:
  • Processor
  • Cache semantics
  • multi-precision

I am interested in use Wolfram in education, specially with info visualization to foster a bran new cognitive model in kids and  adolescents
I'm Tomas, from Mexico. I´ve been a Mathematica fan since the early nineties. Its most important contribution - for me, at least - is that it helped me learn Mathematics properly and without pain, filling gaps in my former education, and letting me try my hand at a few problems which would previously have been out of my reach. I feel I know something and can explain and teach a few things using this system, which I usually introduce to my audiences as a "djinn"  (in the tradition of ancient arabic literature), residing not in a bottle, but inside my Mac, and is a powerful and obedient servant, able to quickly and painlessly complete long and tedious calculations, produce millions of random numbers for experimental simulations in a few seconds, and solve otherwise very difficult problemas - all without a complaint. Nowadays I am retired, but invariably spend a few hours every day doing maths by computer in order to keep myself in good spirits and mental health.

Hi all,
I'm Carlo, I live and work in Naples, Italy. I'm totally new in Mathemetica and in Wolfram Technology in general.
I'm a Certified E.F.F.A.S. Financial Analyst (C.E.F.A.) and I'm a specialist in building models that deal with Corporate Finance, M&A, Management Control, Balance Sheet Analysis, Investment Valuation, etc.
For my job I use Quantrix Modeler, a mutidimensional spreadsheet that works per matrices and that can be used also as BI tool.
I'm thinking to switch to Mathematica so, as you can imagine, this Community is very important for me.

Greetings from Naples.

My name is Paul Beeken and I am currently a physics teacher at Byram Hills High School where I teach advanced and AP physics. My degree is in atomic and molecular physics. I am an experimentalist who started working with Mathematica back in the eighties when I developed computer algorithms and data visualization tools. I have worked with a large number of CAS systems, they all have their strengths and weaknesses but, for me, Mathematica has been the tool I keep returning and use almost exclusively now.

I have worked in a variety of applied research applications before returning to teaching which informs my instructional approach. I am mostly interested in pedagogical applications and developing tools to improve student understanding of physics through data analysis. Lately, I have been also exploring using Mathematica's graphical visualization tools for analyzing student performance and the effectiveness of instructional techniques.

Greetings everybody, I'm Manuel from Taiwan, and is a pleasure to joing.
I just started using mathematica 2 month ago and I love so much to do my research with this language. I'm so happy and I wish to learn more of Mathematica!
I'm a PhD student at NTU taiwan, and my research involves topics like: Kinetic Theory, Statistical mechanics, Semiclassical Boltzmann theory and solve hyperbolic conservation laws with discretizations methods such as TVD, WENO and DGFEM. If anyone is also working on any of this fields lets keep in touch through GitHub

Btw, are we going to see CDF player for notebooks in iOS any soon? ; )

Greetings, I'm Sevrin, but i preffer to be called Sevy!
I just went through the mathematica summer camp, and had a huge amount of fun.  I also learned alot about mathematica, and made a demonstration for the demonstrations project!  Hopefully in the next few weeks it will be uploaded, and i may even be able to edit a link into this reply (i hope, haven't tested this...).  Anyway, i found out alot about mathematica, especially the AstronomicalData function.
Well, unfourtunatley i'm not much for giving out personal info online, so that's it for now!

Edit 1: Yep, i found out i can edit! Will post link to demonstration when (if) it's uploaded!

I am Rob. I am a Mathematica Home user. I have been aware of Mathematica in one way or the other since the early 1980’s. At that time I thought I would like to own a Rainbow computer, install Mathematica and become Dr. Rob physicist. However due to economic reality; I enlisted in the Navy as a nuclear operator Rob instead.

After my enlistment I again became aware of Mathematica while going to college at Colorado School of Mines. I did start with the intention of becoming Dr. Rob Physicist, however; my wife caught pregnancy and I stuffed all my 1st and 2nd semester physics courses into electives and became…. Go to work Rob Chemical Engineer…. In hindsight the most excellent thing/decision that could have happened.

Through the years, I did, however; always maintain some level of fascination with Mathematica. In truth my poor math skills would have precluded me being a great (possibly even adequate) physicist. The language simply eludes me someplace around tensors and eigenvalues, etc. I did, however; think if I could just learn to program my way through the heavy math as I did with spell and grammar checkers through English courses. I may have had a better shot. Well let’s just say I never succeeded at the time…In addition I have never looked back as I truly am happy at Chemical Engineering.

Anyway turn the clock forward some decades and my children in High school and Mathematica 7-8 comes out and computer power is so much cheaper, etc. I finally bought a copy of Mathematica and programed a couple of demonstrations and have been hooked one way or the other ever since. Combine that with the fact that I am enamored with Mr. Wolfram’s contribution of Mathematica and the active documents and the repository of knowledge he makes available and his commitment to people like me via the home user pricing, etc., etc. etc.

Anyway, All in all I am very happy to be here. I have some fuzzy and as yet undefined fully, intention of trying to program and utilize Mathematica in my consulting business. I currently model Chemical Process in several commercially available products I won’t name here. I would like to either write code or possible leverage in System Modeler or? In order to possibly give my end users and clients access to interactive documents so that they can do some of their own “what if” analysis in my deliverables, etc. However, to date, this is a lofty goal given my skill set and time constraints so I remain a Hobbyist with a dream for now.
I'm Blanca Parra, from Mexico.
40 years ago I decided that Math Education was my call. I've been a researcher in this field but, most importantly, a math teacher in every level from Junior High to Post grad education, including training teachers. I retired last year but I continue to teach Calculus and Statistics at college level.
My first Mathematica licence was 3.0.1 or something like that. I still have the very big volume accompanying the software.

Hi everybody,
I'm Ruben Garcia Berasategui and I teach math to last-year high-school students and first-year college students in Jakarta International College in Jakarta, Indonesia.
I've using Mathematica since 1997 when, while in Berkeley,CA, I fell in love with functional programming after discovering the beauty of statements like this:

I'm trying to spread my enthusiasm about Wolfram technologies and functional programming to my students and also to other schools and universities in Indonesia.
I'm currently also the only Wolfram Certified Trainer in ASEAN although I hope that as a result of my activities others will join me soon!

I'm looking forward to sharing experiences about incorporating Mathematica and WolframAlpha in the classroom with other community members.
Salutations! My name is Joshua Towns, and I am the Chief Information Officer at the Indiana Department of Education.

I am looking for innovative ways to incorporate Mathematica technologies in the display, manipulation and analysis of student information, in order to better inform teachers, parents, administrators and policy makers.

I am making the sometimes painful but consistently exciting experience of transitioning from procedural programming to functional programming--and I can think of no better technology to take this journey with! I very much look forward to interacting with you all!

I have been associated to Wolfram since 2006. I have been involved in various projects in the company including some related to languages and computational linguistics, and basic and applied research. I am based in the UK but I often travel to Sweden and the U.S.

I have a PhD in Computer Science from the University of Lille, France, and I am particularly interested in the theory of cellular automata, complex networks, algorithmic randomness, and information theory. And more recently in computational systems biology with particular emphasis to network biology (network reverse engeneering and reconstruction) for hypothesis testing.

As a highlight of my research work, I can mention the conception of a Block Decomposition Method that I conceived together with colleagues, as an extension of the power of an alternative way to measure the Kolmogorov complexity of objects such as strings, images and networks, based on the algorithmic Coding theorem that relates the algorithmic complexity of a string to its frequency of production as a result of running a random computer program.

Feel free to visit my webpage and contact me if you have any interesting projects or have any questions:
where most of my papers are freely available. 

I look forward to meeting people in this great community.

I am a theoretical physicist with specialization in relativity, gravitation, and quantum field theory. My main work has been in curved space renormalization methods and black holes. The very long and tedious tensor calculations in this work lead me to symbolic computation via computer and thus to Mathematica. I was one of the very first users of what became Mathematica in the mid-1980's and using it, I co-wrote the tensor analysis system MathTensor, which has been sold as a commercial product for 25 years.

In the process of doing this work, I started the Mathematica mailing list which evolved into the comp.soft-sys.math.mathematica newsgroup that I moderate. More than 131,000 posts have occurred in that group over the years. I am now a co-moderator of this Community effort.

My other work consists of the creation of packages for the Sun/Oracle operating system Solaris. This can be found in the and web sites. I build and distribute thousands of such packages to many places in the government, military, academic, and business worlds in more than 200 countries and territories.

My consulting company provides assistance to organizations needing help in physics, mathematics, and computing projects and software.

I am also a very avid amateur astronomer.
