IPython: How a notebook is changing science

Talk on the PyCon Sweden 2015 in Stockholm by Juan Luis Cano

Transcript

1. IPython: How a notebook is changing science Python as a real alternative to MATLAB, Mathematica and other commercial software Juan Luis Cano Rodríguez — @Pybonacci Stockholm — 2015-05-12
2. Who am I? • Almost aeronautical engineer • Self-taught Python programmer • Pythonic life: – Pybonacci blog about scientific Python – Chair of the Python Spain Association – Python developer at Airbus Operations – Final Master project: fluid-structure interaction analysis with Python (FEM + SPH) – Personal endeavour: interplanetary trajectory analysis with Python
3. Let's get to the point
4. Russell's teapot
5. Russell's teapot “If I were to suggest that between the Earth and Mars there is a china teapot revolving about the Sun in an elliptical orbit, nobody would be able to disprove my assertion provided I were careful to add that the teapot is too small to be revealed even by our most powerful telescopes.
6. Expectations...
7. ...and Reality™
8. Is there a better way?
9. IPython notebook
10. What is this IPython notebook? • Interactive Python interpreter in the browser • Open format combining executable code, text and multimedia • Inspired in Mathematica • Based on the Python programming language Demo! http://www.nature.com/news/ipython-interactive-demo-7.21492
11. The counter- analysis in a notebook
12. Python *Demand of Python programmers for Big Data jobs doubled in the last twelve months, says Forbes
13. Teaching tool • Book: Bayesian Methods for Hackers • Lorena Barba courses: • AeroPython* • 12 steps to Navier Stokes • Practical Numerical Methods with Python • Harvard CS109 Data Science *Not to be confused with our AeroPython ;)
14. ...the rise to fame
15. More articles!
16. Some myths → There's no support → Won't be free forever → Free software has bugs
17. Some myths → There's no support Enthought, Continuum Analytics → Won't be free forever → Free software has bugs
18. Some myths → There's no support Enthought, Continuum Analytics → Won't be free forever Free software belongs to the community → Free software has bugs
19. Some myths → There's no support Enthought, Continuum Analytics → Won't be free forever Free software belongs to the community → Free software has bugs Naturally.
20. Can we trust CAS?
21. Moral: Free software has bugs
22. World domination?
23. Ju·py·ter /ˈdʒu pɪ tər/ noun 1. the future incarnation of IPython. Julia + Python + R
24. Project Jupyter • Separation of the language-agnostic components – Jupyter: protocol, format, multi-user server – IPython: interactive Python console, Jupyter kernel • Jupyter kernels = Languages which can be used from the notebook (33 and counting) • Surprises are coming...
25. ¡IMatlab!
26. Some recent events May 7th, 2015: • GitHub + Jupyter notebooks = <3 https://github.com/blog/1995-github-jupyter-notebooks-3 • Embracing Jupyter Notebooks at O'Reilly https://beta.oreilly.com/ideas/jupyter-at-oreilly ...that scalated quickly!
27. Further resources • Official Python tutorial on python.org • Langtangen “A primer on Scientific Programming with Python” • “Curso de Python para científicos e Ingenieros” on YouTube (in Spanish) • AeroPython #0 with installation and getting started instructions (in Spanish) • Software Carpentry, programming for scientists and engineers • MOOCs at Coursera, EdX...
28. No more teapots :)
