Octave GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. The Octave language is quite similar to Matlab so that most programs are easily portable. Octave is distributed under the terms of the GNU General Public License. Version 4.0.0 has been released and is now available for download. An official Windows binary installer is also available from Thanks to the many people who contributed to this release!
advice John Baez March 25, 2007 I have reached the stage where young mathematicians and physicists sometimes ask me for advice. Here is my advice. Most of it applies to grad students and postdocs in any branch of science who seek an academic career involving research. On Keeping Your Soul The great challenge at the beginning of ones career in academia is to get tenure at a decent university. The great thing about tenure is that it means your research can be driven by your actual interests instead of the ever-changing winds of fashion. To do this, you have to make sure you never lose that raw naive curiosity that got you interested in science in the first place. In our acquisition of knowledge of the Universe (whether mathematical or otherwise) that which renovates the quest is nothing more nor less than complete innocence. So: keep playing around with all sorts of ideas, techniques and tools. Some Practical Tips Go to the most prestigious school and work with the best possible advisor. home
Envisioning Julia sets The Julia set is approximated by the black dots in the image below. The set is generated by a function. The arrows highlight the working of the function. The dark red arrow represents an input point as a direction and distance from the center of the plot. We first double it's angle relative to the right-hand axis and then take the square of the distance from the center, called the magnitude of the point. click the images for an interactive version The Julia set is infinitely deep, but the computer displays finitely-sized pixels. What we have looked at so far is but one Julia set. But the basic properties of Julia sets we explored above are still valid.
Construire une éolienne - Fabriquer une eolienne à axe vertical Mathematica With energetic development and consistent vision for three decades, Mathematica stands alone in a huge range of dimensions, unique in its support for today's technical computing environments and workflows. A Vast System, All Integrated Mathematica has over 6,000 built-in functions covering all areas of technical computing—all carefully integrated so they work perfectly together, and all included in the fully integrated Mathematica system. Not Just Numbers, Not Just Math—But Everything Building on three decades of development, Mathematica excels across all areas of technical computing—including neural networks, machine learning, image processing, geometry, data science, visualizations and much more. Unimaginable Algorithm Power Mathematica builds in unprecedentedly powerful algorithms across all areas—many of them created at Wolfram using unique development methodologies and the unique capabilities of the Wolfram Language.

Engineering ToolBox inventeurs et leurs inventions "Encore quelques générations qui passent, et nos machines seront conduites par la force obtenue à n'importe quel point dans l'univers... C'est une simple question de temps et les hommes réussiront à connecter leurs machines aux rouages mêmes de la nature." - Nikola Tesla En effet, il a été démontré que le vide contient une énorme quantité d'énergie, proche du zéro absolu (le point zéro), une énergie utilisable en abondance : L’énergie libre, ou énergie du vide (éther). C’est une source d’énergie renouvelable disponible gratuitement appelée aussi « énergie du point zéro ». Les recherches révèlent que cette source d’énergie peut être partiellement convertie en énergie utilisable. Imaginez-vous que cela existe depuis 20 ans: en avez-vous déjà entendu parler? Il existe beaucoup d’inventeurs indépendants qui ont construit des machines à énergie libre et dont les résultats ont été publiés au grand jour et vérifiés Viktor Schauberger R.
