Every Decision Is Just Math Underneath.

this is the lecture I wish I found five years ago. MIT's Jake Xia breaks down financial markets from the ground up, not with buzzwords, with the actual structure practitioners think in. how markets are structured. how products are classified. how participants actually interact. why that foundation comes before any pricing model. and it's all open courseware. zero paywall. If you're serious about finance, this is where you start.

This MIT lecture is the skeleton key to understanding markets. Andrew Lo, the man who built Adaptive Markets, breaks down why the "efficient markets" story you were taught is incomplete. Markets are not machines. They are ecosystems. And ecosystems do not care about your model. Once you see it, you cannot unsee it.

MIT will teach you how Wall Street measures risk, for free. This lecture covers Value at Risk (VaR): the variance covariance method, Monte Carlo simulation, historical simulation, and how banks actually use these models in practice. No $200K tuition required. Just your curiosity. If you're in finance and haven't watched this, add it to your list.

Random Walks are not "just theory." They're one of the foundational models for decision-making under uncertainty. Robert Gallager's MIT lectures cover the full arc: Markov Processes → Random Walks → Hypothesis Testing → Thresholds. A pipeline that shows up everywhere: from stochastic modeling to signal detection to optimal stopping. This is the math your systems are built on. Know it.

Spent some time with this MIT lecture on game theory. The part that stuck: a VCG auction is designed so that lying about your valuation can never make you better off. Bookmark this before it's lost! Most market mechanisms aren't built that way. Most reward the best liar. Worth knowing which kind of game you're actually playing.

MIT published a full lecture on risk-neutral pricing and Black-Scholes equation. It covers forward contracts, options valuation, stochastic calculus, and why derivative prices depend on volatility. To all quants out there turn on Notifications, new article will be out tomorrow!
