Previously we wrote about mathematical “puzzle” originating from a TV game (see the description of the Monty Hall problem). This time we shall consider the opposite case – the mathematical “game” used as a base for a TV game. Watch a fragment of the “Golden Balls” final stage called “Split or steal”.
The game is very simple, yet it possesses no correct solution or optimal strategy. Interestingly enough it can also be used as model for understanding social behavior of humans.
Žaidimo esmė yra elementari, bet kaip nebūtų keista – teisingo sprendimo ar laiminčios strategijos čia nėra ir negali būti. Įdomu ir tai, kad toks elementarus modelis gali būti panaudotas žmonių visuomeniškumo ir egoistiškumo supratimui 1.
The most active and well known scientists contributing towards FuturICT project have organized their ideas into few articles, which discuss the current situation in contemporary complex social system modeling. These articles we published in a special issue of “The European Physical Journal Special Topics”. Most of the articles are available for free, thus we invite you to familiarize yourselves with them.
Recently on my Facebook news feed I found one article, which was rather interesting. “Teaching mathematics differently?” – ironical thought crossed my mind, while at the same time recalling some stand up comedians telling “wild” stories about the problem-based learning. It is truly funny to hear that children nowadays are forced to help the squirrel to count the nuts! Or to solve another default setup: “10 apples + 4 pears = 48 Litas, while 5 apples + 6 pears = 32 Litas, if so then how many Litas does a single apple or pear cost?” Why should anyone solve this problem in this way? Can’t the client just look up the price tags? Or check his receipt? Continue reading “Teaching math in a different way” »
Previously, approximately 2 years ago, we have written that we published a review of our works 1 in a book by open-access publisher. Recently we discovered that during the recent two and a half years this books was downloaded almost 7000 times (namely 8 times per day). It was downloaded by the people all around the world – with the USA, China, India, Japan, Germany being the most active countries in the process. It is an excellent result!
While being happy with excellent “diffusion” of our ideas via open-access publisher, we would also like to speak about the improving statistics of the Physics of Risk website. In 2012 we expect to be visited 12 thousand times! It is slightly better than in 2011, in which we had 11 thousand visits. Improvement is small, yet promising a bright future.

Recent hurricane, which struck east coast of the USA, has very interesting symmetry properties. This natural phenomenon obeys the golden ratio! Well at least such information has been circulating on the science.memebase.com! Similar properties are also observed in some fractals such as Penrose tiling (we have not yet discussed this fractal on Physics of Risk, thus we’d like to recommend reading an article on the Wikipedia).

Topic: “Physics is not a risk: Brief introduction into the Physics of Risk” Speaker: Aleksejus Kononovičius Briefly: Social sciences have accomplished many different things. Yet it should be evident that there is a place for improvements – to look into the old and new social problems a bit differently. As many of the social problems are strongly non-linear and very complex, the physicists’ point of view is very useful. This, new, point of view is known as Physics of Risk. When? 18th of October, 17:00. Where? VU Faculty of Physics (Saulėtekio al. 9, III rūmai, Vilnius), 201 auditorium. Organized by:VU Faculty of Physics Students Scientific Association. Facebook event:here.
Modern science strongly relies on the computer modeling. Most of the models in the complexity science, the object of the Physics of Risk, requires computer modeling and usually may not be dealt with analytically. For a person familiar with the computer modeling it should be known that the variety computer algorithms is very large and that there also is a variety of ways to understand these algorithms. Thus each person might solve the same complex task slightly differently and thus produce slightly different results. This brings us to the point that in order to comprehend what has been done by a certain scientist one should not only study the equations and assumptions made by him, but one also needs to have access to the source code of the software used by that certain scientist.
Yet there is still a problem that only few scientists to make the source code of their software public available. This behavior is not very desired as in order to reproduce the same results other scientists must make a lot of efforts. Some times the attempts to reproduce published results fail. This problem may be solved by encouraging adoption of the open source ideas by the scientific community.
We, the contributors of Physics of Risk, have already faced the negative effects of the closed source culture, thus most of our models made available on Physic of Risk are published together with their source code. Though it is well hidden inside the applet’s JAR archive (open it with any modern archiver, inside you should find java file, which contains the source code).
