Main topic: General information

Under this topic we cover general information, which is unrelated towards certain models or their presentation. Thus most of the posts related to this topic will talk about the project itself or technical supervision of Physics of Risk website. We will also write about our newest scientific publications and visits to different scientific conferences.

Prisonner’s dilemma

Posted on April 29, 2013.

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.

Research Council of Lithuania has announced a call for applications for students’ research practice in Lithuania in summer of 2013. The contributors towards Physics of Risk website, dr. (HP) Vygintas Gontis and PhD student Aleksejus Kononovičius, offer two topics for the research practice. The offered topics are mainly based on the following topics, previously published on this website:

More information is available from the Research Council of Lithuania website (see the call here) and from the portal dedicated to the project “Promotion of Students’ Scientific Activities” (see here).

FuturICT: participatory science and computing for our complex world

Posted on January 14, 2013.
futurict

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.

Teaching math in a different way

Posted on December 31, 2012.
monty-hall

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” »

The importance of open access in science

Posted on December 17, 2012.

The creators of the well known science related web comic offer everybody a chance to become familiar with the open access philosophy (video taken from http://www.phdcomics.com/comics.php?n=1533).

Download rates of our open-access review

Posted on December 3, 2012.
StochasticControl788_big

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.

On the stochastic theory of nonequilibrium steady states

Posted on November 19, 2012.
ruseckas

In October 2012 our group has familiarized themselves with this interesting theory. Few seminars, which were held at VU ITPA, on the stochastic theory of nonequilibrium steady states were read by dr. Julius Ruseckas, one the researchers in our group. This theory is discussed in two articles recently published in the Physical Reports journal 1, 2. Read on Continue reading “On the stochastic theory of nonequilibrium steady states” »

Quantum mechanics + statistical physics = ?

Posted on October 29, 2012.

Quantum mechanics and statistical physics use very similar and inter-connected concepts. Ex. the latter is concerned with distribution and probabilities, while the former operates with wave functions and amplitudes. Even the essential equations, master and Shrodinger, appear to be similar:

The only difference is the imaginary factor i! But these similarities lie just on the surface… Continue reading “Quantum mechanics + statistical physics = ?” »

Seminar at VU Faculty of Physics: Brief introduction into the Physics of Risk

Posted on October 16, 2012.
kononovicius

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.
