I talk to robots while driving. “We jumped from discussing Cooper Flagg’s basketball stats at Duke to comparing Carlo Rovelli and Brian Greene’s competing theories of physics to talking about the history of San Francisco. In a daring feat of economic analysis, I asked it to calculate if the after-tax returns of two ETFs were statistically significant & to compare the energy portfolios using the 13-Fs of a few hedge funds for investment ideas.

The team, led by researchers at China's Zhejiang University, leveraged this insight through its work and developed an innovative gas sensing material to create a screening process.” ~ learn more

A new algorithm for uncovering causality in complex systems. Created by a team of MIT engineers, “The algorithm determines the specific nature of that relationship, such as whether two variables are synergistic—meaning one variable only influences another if it is paired with a second variable—or redundant, such that a change in one variable can have exactly the same, and therefore redundant, effect as another variable.” ~ learn more
