Probably everyone has at least once have been stuck in the traffic jam. But most probably not everyone had thought about the possible relationship between the complexity science and traffic. For quite a long time it was thought that traffic jams can be caused by noticeable events on the road – car crashes, road works and etc. But in the recent decades number of cars in the streets grew rapidly and it was noticed that sometimes traffic jams form without any obvious reasons. In this text we present a simple traffic model by Nagel and Schreckenberg, which predicts traffic jams occurring due to small errors made by drivers themselves. Continue reading “Stop-and-go waves”
Physics of Risk is becoming more and more popular and gaining more attention from the media. This time our permanent contributor Aleksejus Kononovicius gave an interview to a journalist Marija Rudzevičiūtė from Bzn start. The original article was published in Lithuanian language, but here you can find its free form translation to English.
“Probably most of us were stuck in a traffic jam for at least once in our life. Some of us were certainly stuck in a traffic jam, though there were no car crash, no road works or no other apparent reason for the road to be jammed. Yet all cars move in a jerky motion – they suddenly accelerate, move a bit and then suddenly stop. The reason lies in a small errors made by the drivers themselves”, everyday situation in a large city is reviewed by Aleksejus Kononovicius, younger research fellow at Institute of Theoretical Physics and Astronomy, Vilnius University. He is also a current contributor to the “Physics of Risk”, a website which presents an idea that “more physics – less risk” for a broader society. Continue reading “Not that good at physics? Your business might be at risk…”
Originally I have written this article back in the end of 2013 and submitted it to a pop-science article contest organized by three locally well-known pop-science blogs “Mokslo sriuba” (en. Science soup; online pop-science web-show), technologijos.lt (en. technology; general science news portal) and konstanta.lt (en. constant; very popular blog dedicated to astronomy and astrophysics). The article was rather successful and won the scientific jury prize in the contest!
Now, after the contest has ended, I can publish this article (and its English translation) on “Physics of Risk”. So… read on! Continue reading “Statistical physics – a key to understanding of the social and economic complexity”
Recently while zapping over TV channels one program on the Discovery Science channel caught my attention. So have started watching “Weird connections” episode “Law of the Urinal” out of pure general interest. Yet after finishing watching it I thought that it should prove to be very interesting in a context of Physics of Risk. Thus I would like to encourage you to watch it on the Discovery Science channel (as far as I know it is being shown again from time to time) or on the vimeo.com website.
For the first time in history of the Cafe Scientifique organized by Student’s Scientific Association of Faculty of Physics of Vilnius University the event was recorded on the video (special thanks to the webseminarai.lt team)! Which very useful to us as we can now share for all people who are interested in the popular side of Physics of Risk. We invite everyone interested to view the video (though note that everything is presented in Lithuanian) Continue reading “Cafe Scientifique “Physics of Risk: the more physics, the less risk” video recording”
Topic: “Physics of Risk: The more physics, the less risk”
Speaker: Aleksejus Kononovičius
Briefly: I will talk about the complexity of socio-economic systems and how physicists (and not only physicists) attempt to understand, describe and explain it. I will present some of the research done worldwide and also research done at VU ITPA.
When? 6th of November, 19:00.
Where? Cafe “Savas Kampas” (Vokiečių st. 4, Vilnius)
Organized by: VU Faculty of Physics Students Scientific Association.
Facebook event: here.
Slides: Download (without video; Lithuanian).
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.
