Chaos at fifty
In 1963 an MIT meteorologist revealed deterministic predictability to be an illusion and gave birth to a field that still thrives.
Niels Bohr between physics and chemistry
Bohr’s atomic theory was addressed as much to chemical problems as to physical ones. But the great scientist’s intent to establish a new framework for atomic and molecular chemistry was less successful, and was unacknowledged by most chemists.
Getting a grip on the electrical grid
As our electrical grid systems become smarter and more autonomous, they require greater control technologies to protect them from failing.
