Political Mathematics
(I don't understand why explaining choices using numbers/open models is political but I guess creating clarity is deemed a political objective in this era of alt-facting):
• MALT=Mortgage-Analysis-Learning Tool, 3rd project/working App '16/'17;
• Tax analysis learning tool, 3rd project/making a working App on tax choices explained for all, in progress, '17/'18;
• On falsification/verification of Boris Johnson's/Leave's claim ``We send the EU 350M a week; let's fund our NHS instead'':
(i) Google UK's annual EU contribution; see from the table that it is 11342M Euros per annum.
(ii) Divide 11342M per annum by 52 weeks, yielding 218.1M Euros per week.
(iii) Dividing by the Euro/pound rate of 1/0.8910 (on Oct 25th 2017) gives 245M per week which is significantly less by 75M per week than Johnson's 350M per week.
(iv) Moreover, putting this 245M per week in the NHS after Brexit would imply that the EU contributions on science, various projects in Wales and such will not be replaced by UK contributions.
(v) Draw your own conclusions from these simple calculations on whether Johnson & co. were disingenuous or not.
(vi) The point of the above is that anyone could have done these checks. I finally checked matters on Sept. 2017 (facebook post) and the next day it emerged in The Guardian but without explaining how simple this calculation is. Anyone can do this check.
Studying waves with mathematics is fun!

Roaring movies GFD: on hydraulic and granular bores.

Geophysical fluid dynamics (GFD) concerns the fluid motions of the atmosphere and ocean, and environmental dynamics such as river and coastal flows. This includes floods, beach erosion due to breaking waves, tides, and weather prediction.

My particular interest is in the applied mathematics of GFD: design and testing of laboratory configurations for validation of mathematical models, computational techniques for PDEs (DGFEM), Hamiltonian fluid dynamics, and hydraulic solutions of hyperbolic systems. I also investigate geological and industrial problems related to GFD. Examples are safety of underground storage sites due to break throughs (of volcanic magma) and granular flows in blast furnaces.
