Russian Spirals

The production line has been producing Russian spirals at a rather speedy rate. The multitude of options available for combinations of shapes, colours and sizes has provided a chance for a lot of experimentation :)

From left to right:
  • Purple size 11 with turquoise triangles
  • Teal size 8 with size 11 bronze
  • Silver size 8 with size 11 pink
  • Combination of size 11 lilac and silver and size 8 purple
  • Blue size 11 with iridescent squares
  • Red size 11 with grey squares
  • Turquoise squares with size 11 silver
  • Black size 8 and size 11 silver 
As you can see, the options are endless. So many more options to try...Any suggestions?

Pythons, pandas and ferrets: The zoo of tools for atmospheric scientists

Sitting in a postgraduate group meeting a few weeks ago, the modelling students were discussing the various tools available used. One social scientist commented that to an outsider the conversation sounded highly amusing, and to those not familiar with the tools, I suppose discussing ferrets, pythons, Fortran, C and R sounds like a cross between a zoo and alphabet soup.

Why all these different tools? Legacy....

Fortran is the backbone of all climate models, used mainly for its numerical core that some argue is still faster then C etc. (they just don't want to port the system to a newer language). One programmer described reading Fortran is like scratching your own eyes out...pretty graphic!

Then comes C, the quintessential language of the engineer.

Ferret is a scripting language for environmental applications.

Python is an interpreted language that is has evolved over time, it used to be incredibly slow to manipulate data, but the modifications have sped up calculations and new modules have made python a welcome addition to the scientific zoo. SciPy, NumPy, pandas make it possible to do R comparable (actually fixed issues in R) calculations. Matrix manipulations have never been better.
