**Tower of Hanoi: scala and scala-js**

For a talk to school students, had solving the

*Tower of Hanoi*in scala recursively and animating it using scala-js (with scalatags, svg).

It took me four years to write the paper "Five stages of accepting constructive mathematics", which is based on an eponymous talk I gave at the Institute for Advanced Study in 2013. The paper has been published in the Bulleting of the AMS. I hope you'll enjoy it!

**The cost of a proof**

A rough calculation to see how expensive it would be to do the computation for the world's largest proof:

* On the google compute engine, a

*preemptible*processor costs $0.015 per hour

* So 800 processors (which is the number used for this computation) cost $12 per hour. (I assume that the processors in the two cases have roughly the same power).

* The computation ran for two days, say 50 hours.

* Total cost estimate : $600

Of course one has to add storage etc, but still the cost is quite reasonable - even in India about two months stipend of a research student.
