How Much Wood Would A Woodchuck Chuck If A Woodchuck Could Chuck Wood?

From "Strategic Humor" in HBR Sep-10 . We, lumberjacks, could if we should - To Tree Or Not To Tree ;)


This has a serious background, because we still find tree based methods even in newer quant finance presentations nad discussions. To make no mistake, tree-based methods are great for understanding, say, the option theory, but they are firewood if applied as solvers of complex financial PDEs. 

The Evermore Working and Frequently Updated FACTORY

A customer sent us this picture. With eyes twinkle, he asked us whether we will deny our already confirmed and scheduled update installation? And whether we have grown in the mean time and make business decisions on the street ;) ?

Do We All Need To Become Philosophers?

In my first short post about The Blank Swan , see The Market Of The Future, ... I mentioned that I find the thoughts behind this book present such a revolutionary way of treating derivatives pricing and technology that I placed it on the shelf with the books that influenced my thinking most.

Shanghai - the city that never sleeps

When I arrived in Shanghai, I thought "There is so much life in this city." People doing their businesses, thousands of busses at the EXPO parking area, a hotel dedicated to service their customers at the highest level, and Shawn Liu and his team having organised a perfect event for the following day.

Shanghai After Noon

Shawn Liu from China Quants (right picture) perfectly organized a program-rich UnRisk Shanghai 2010 Tour that brought us together with financial experts from the commercial sector to research institutes.

The Blank Swan Of Free Metal Forming

Just take the simplest process of free metal forming: bending, you need to understand the framework of the elastoplasticity theory and the complexity and limits of its mathematics derived from the mathematics of continuum mechanics. Deformation is decomposed (replicated?) into elastic and plastic parts and for simplicity decompositions shall determine stress and kinematical quantities.
However, resulting PDEs can be solved by finite element schemes. They "only" need to be calibrated related to the physical properties of the material that are dependent on recipes, and properties that are result of the process - like rolling and thermal treatment? And work as predictive models for angles?

Market Of The Future, Or Market With Future?

After having read many things about it, I read, The Blank Swan - The End Of Probability, Elie Ayache, author.
Yes, the thought behind the book is deeply challenging (Dan Tudball, Editor of Wilmott magazine). Ayache himself: I tend to only write the things that will be as difficult to read as they were to write. IMO, there is also an "economic aspect" of writing and reading and one might also think of the ink-factor one brings to reading. But this does not say anything about the quality which cannot be measured by operational semantics (like computational knowledge), only about my Blank Swans (as drawn in the picture here)
