حل عقدة رياضية عمرها 90 عاماً ومكافأتها مليون دولار.. في 88 ساعة فقط! 🚨🧮💥

​10,000 وكيل ذكاء اصطناعي من OpenAI حسموا لغز معادلات Navier-Stokes الفيزيائية الشهيرة التي عجز عنها كبار العلماء لعقود!

​كيف تحققت هذه المعجزة العلمية؟
• جيش رقمي منظم: تعمل 10 آلاف نموذج بالتوازي، تبادلت 2.7 مليون رسالة وأنتجت 130 مليار توكن في بيئة بحثية واحدة.

• سرعة خيالية: استغرق إنتاج الإثبات العلمي 88 ساعة فقط، بينما قضى GPT-6 Astra حوالي 17 ساعة إضافية للتحقق منه برمجياً عبر لغة Lean!

• النتيجة: إثبات امكانية حدوث انفرادية وتصاعد السرعة بلا حدود في ظروف معينة لمائع كان ساكناً.

​الذكاء الاصطناعي لم يعد مجرد "مساعد" لعلماء البشر.. بل أصبح يمثل مختبرات بحثية كاملة تختصر عقوداً من العمل البشري في أيام معدودة! ⚡️🔬

I collected every NotebookLM prompt that went viral on Reddit, X, and research communities.

These turned a "cool AI toy" into a research weapon that does 10 hours of work in 20 seconds.

16 copy-paste prompts. Zero fluff.

Steal them all 👇

📚 In summer 2023, my book Causal Analysis was published with @mitpress. Just two years later😉 I’m very happy to share that the lecture slides are now freely available in both PDF and LaTeX (as zip files), along with the datasets and R/Python code:

Mathematics. Prime Number Galaxy.

In 1994, Robert Sacks invented a way to detect patterns in numbers. Non-negative integers are plotted on an Archimedean spiral rather than the square spiral used by Ulam. Remarkable structures are highlighted by using small disks with diameters equal to the number of dividers for each number. The prime numbers are therefore represented by a disk of diameter 2.

We have a new post 🙃
Three recent DiD papers, one shared goal: better estimates in messy settings
☑️DiD that hits efficiency bounds
☑️Synthetic DiD that mimics an oracle
☑️TWFE vs. the new wave

"Probability is the logic of science."

There is a deep truth behind this conventional wisdom: probability is the mathematical extension of logic, augmenting our reasoning toolkit with the concept of uncertainty.

In-depth exploration of probabilistic thinking incoming.

Definitivamente el futuro de la enseñanza de econometría (y otras cátedras de economía) va a sufrir cambios y saltos drásticos con el uso de inteligencia artificial. Un artículo llamativo al respecto: https://t.co/TvgE6AbhI4

In 1921 George Pólya proved that a person almost surely would return to his starting point in a 2-D random walk, but for 3 dimensions or higher, the probability of returning to the origin decreases as the number of dimensions increases! In 3-D , the probability decreases to ~34%. The mathematician Shizuo Kakutani was known to refer to this result with the following quote: "A drunk man will find his way home, but a drunk bird may get lost forever".
