“Jump to 2017, when Google unveiled AlphaZero, a computer that had been given the rules of chess and then taught itself how to play. It took four hours of training to be able to beat Stockfish, the best chess machine programmed with human tactics. Intriguingly, AlphaZero made what looked like blunders to human eyes. For example, in the middlegame it sacrificed a bishop for a strategic advantage that became clear only much later.
Quant funds can be divided into two groups: those like Stockfish, which use machines to mimic human strategies; and those like AlphaZero, which create strategies themselves. For 30 years
quantitative investing started with a hypothesis, says a quant investor. Investors would test it against historical data and make a judgment as to whether it would continue to be useful. Now the order has been reversed. “We start with the data and look for a hypothesis,” he says.”

Building a Career, One Academic Step at a Time

““The four-year undergraduate experience is often out of reach for large segments of our population,” said Kemi Jona, associate dean for digital innovation and enterprise learning at Northeastern University in Boston. Moreover, he said, “the idea of getting that one degree and you’re set for life doesn’t really hold water anymore. Then the question becomes, ‘how do we make it easier for working adults and people who need to pick up new kinds of tools and technologies?’”
The answer: stackable credits, which Cassandra Horii, director of Caltech’s center for teaching, learning and outreach, defined as “a more bite-sized piece of education that stands on its own and has value in the workplace.” But “if you continue on your educational trajectory, that piece fully counts towards your next educational step.”
The stackable term itself, noted Jimmie Williamson and Matthew Pittinsky in an article in “Inside Higher Education,” is “clever, invoking the image of Lego blocks and the metaphor of assembly.”” “}}

An example is the combination of rigidity and flexibility in protein-based teeth of the squid sucker ring. Other examples are time-delayed actuation in plant seed pods triggered by environmental signals, such as fire and water, and surface nanostructures that combine light manipulation with mechanical protection or water repellency. Bioinspired engineering transfers some of these structural principles into technically more relevant base materials to obtain new, often unexpected combinations of material properties. Less appreciated is the huge potential of using bioinspired structural complexity to avoid unnecessary chemical diversity, enabling easier recycling and, thus, a more sustainable materials economy.
