🎞 Doyne Farmer - How can we understand our complex economy?
https://www.youtube.com/watch?v=GPKmFEDLh5E
We are getting better at predicting things about our environment - the impact of climate change for example. But what about predicting our collective effect on ourselves? We can predict the small things, but we fail miserably when it comes to many of the big things. The financial crisis cost the world trillions, yet our ability to forecast and mitigate the next economic crisis is very low. Is this inherently impossible? Or perhaps we are just not going about it the right way?
The complex systems approach to economics, which brings in insights from the physical and natural sciences, presents an alternative to standard methods. Doyne will explain this new approach and give examples of its successes. He will present a vision of the economics of the future as it confronts the serious problems that our world will face.

متاسفانه خبردار شدیم که امروز صبح، فلیپ اندرسون فوت کرده. اندرسون برنده جایزه نوبل در فیزیک و از پیشگامان فیزیک ماده چگال و سیستمهای پیچیده بود. جمله معروف «بیشتر، متفاوت است.» از او به ارمغان مانده.

Forecasts by Country
On this page, we present the 6-day forecasts of COVID-19 case counts by country based on a novel epidemiological model that integrates the effect of population behavior changes due to government measures and social distancing.

سه استراتژی برای شکست کرونا در ایران + هزینهها
کشور در آستانه یک بحران فراگیر قرار دارد و به اعتقاد بسیاری از کارشناسان پاسخ درست و یا اشتباه به بحران کرونا میتواند مسیر تاریخی ایران را تغییر دهد، اهمیت مساله تا جاییست که بسیاری از کشورهای جهان کرونا را بزرگترین بحران خود پس از جنگ جهانی دوم میدانند،…
🕯 Epidemiological models aren't crystal balls that predict the future, nor are we sure if their parameters are correct! That's okay because that's not what they're for. Let's treat them as what they are: the future imploring us to choose our fate.

Bridging the gap between graphs and networks
Gerardo Iñiguez, Federico Battiston, Márton Karsai
https://arxiv.org/pdf/2004.01467
Network science has become a powerful tool to describe the structure and dynamics of real-world complex physical, biological, social, and technological systems. Largely built on empirical observations to tackle heterogeneous, temporal, and adaptive patterns of interactions, its intuitive and flexible nature has contributed to the popularity of the field. With pioneering work on the evolution of random graphs, graph theory is often cited as the mathematical foundation of network science. Despite this narrative, the two research communities are still largely disconnected. In this Commentary we discuss the need for further cross-pollination between fields -- bridging the gap between graphs and networks -- and how network science can benefit from such influence. A more mathematical network science may clarify the role of randomness in modeling, hint at underlying laws of behavior, and predict yet unobserved complex networked phenomena in nature.

🕸 نظریه گراف و علم شبکه
نزدیک به ۲۰ ساله که چیزی به اسم نظریه شبکه یا علم شبکه در ادبیات علمی پیدا شده. شاید نزدیکترین یا نامآشناترین نظریه به علم شبکه، نظریه گراف در ریاضیات باشه. چیزی که از زمان اویلر (۱۷۳۶) شکل گرفته و در چند قرن اخیر هم همیشه حوزهی پژوهشی برای ریاضیدونها بوده. اما این فقط ظاهر کاره...
