Incredible! And it was great to supervise Lucas last summer. Over the next few years, we have big plans to get our Computer Science undergraduates @ChCh_Oxford working on the open source libraries that power science and technology worldwide.
Oxford Comp Sci@CompSciOxford

We are proud to share that Computer Science & Philosophy student Lucas Colley has been made a maintainer of SciPy (@SciPy_team), a free, open-source software library. This is very exciting news, congratulations Lucas! Read more here: chch.ox.ac.uk/news/lucas-col… #compscioxford

@amirvaxman_dgp I've been in this situation for a long time, needing to visualize 3D scenes (meshes, volumes, objects, whatever) in Python. There are many newer cool libraries, but to be honest the thing that has always worked for me is VTK. Just plain VTK. If you want a GUI, embed it in PyQT.

What are the cool kids using nowadays to visualize modest 3D scenes in Python? I mean like examine a mesh or show some simulation of rigid bodies on an infinite plane etc.

@Peter_shirley To be clear, you have a stack of single-channel float images? Then I think what you want is np.argmax using the axis keyword, where axis is the stack dimension.

Hey numpy gurus: I have a N same-size numpy arrays of floats... I label then O..(N-1). I want to create an image that for each pixel has the index of the image with the largest value in that pixel. Straightforward with loops. Is there some clever array operation method?

@john_pryan Other option - numerical integration! But doing just one numerical inverse Laplace transform is hard enough, let alone three.

@john_pryan To be clear, is that a triple Laplace transform (e.g., x, y, and z are all Laplace-transformed variables)? Would have to know more to say more, but if there is no simple closed form you can sometimes derive infinite sums by applying the residue theorem in the contour integration.

What approaches are worth attempting to get the inverse laplace transform of this multivariate function? Don't think a simple closed form exists, but any infinte sum would be useful. The 2d case (polyagamma distribution) is an infinite sum of gamma rvs.

The first thing you notice when you walk into Bill Gates’s private office, just outside Seattle, is a wall-size installation of the periodic table with a sample of each chemical element in its own glass-fronted vitrine [source: ow.ly/OkJm50vHJqr]

It's been extraordinary to grow Computer Science at Christ Church from scratch with @yaringal. We're rightly proud of our students, are now expanding again, and encourage anyone thinking of studying Computer Science at Oxford to apply!
Christ Church@ChCh_Oxford

5 years ago, ChC started offering Computer Science and it's now one of the largest subjects. Our CS students recently met with our Research Student Sir Tim Berners-Lee to discuss the history of the Web and the significance of "//" after "http:" #MuChChLove

@Kaju_Nut @martinmbauer Far too much focus on quantum (at least 3 courses) versus almost nothing on certain classical topics (like fluid mechanics).

If you went to University for physics, what topic was covered that you think was overemphasized or should not have been covered at all? (Inspired by @martinmbauer's recent question)

To my own immense surprise, from September I will be Lecturer in Greek Culture and Classical Receptions at the University of Liverpool. The end of the beginning.
