5000 Demonstrations

Wolfram has passed 5000 demonstrations published by the Wolfram Demonstrations Project. Congratulations!

Conrad Wolfram has announced this in Wolfram Blog .
I often visit this site myself. My interest is broad, but especially I browse application-oriented demonstrations (business, engineering, systems, ..).

As UnRisk developers, we use Manipulate quite extensively. How? In quantitive finance tasks can become complex and bear the danger of model and method risk that can become horrible in interplay. We test our models, algorithms and calibration schemes across comprehensive scenarios, not forgetting the pathologic cases. In the above visualization you just see a single spot of such a dynamic visualization; the price and the vega of a complex convertible bond over the price of the underlying and time to maturity. If you do not solve the related PDE correctly and robust you get severe mis-pricing and misleading hedging parameters. 

The significance is new insight without additional effort
