When machine learning is used to suggest new potential scientific insights or directions, algorithms sometimes offer solutions that are not physically sound. Take, for example, AlphaFold, the AI ...

A new study by physicists and neuroscientists from the University of Chicago, Harvard and Yale describes how connectivity among neurons comes about through general principles of networking and ...

Sometimes the universe is just too complicated to analyze. Heck, if you take a tennis ball and toss it across the room, even that is practically too complicated. After it leaves your hand, the ball ...

Both physical and economic phenomena may possess universal features that could be uncovered using the tools of physics. The principal difference is that in economic systems -- unlike physical ones -- ...

This is a preview. Log in through your library . Abstract A simple stochastic model for resource-limited populations is proposed and its properties examined by simulations. Features of the model are ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 87, No. 1 (Jan., 1990), pp. 429-433 (5 pages) In this note I present a simple model for the idiotypic network ...
