The Fascinating Science of How We Think Not with the Brain But with the World

In The Extended Mind: The Power of Thinking Outside the Brain (public library), Annie Murphy Paul explores the most thrilling frontiers of this growing understanding, fusing a century of scientific studies with millennia of first-hand experience from the lives and letters of great artists, scientists, inventors, and entrepreneurs. Challenging our cultural inheritance of thinking that thinking takes place only inside the brain, she illuminates the myriad ways in which we “use the world to think” — from the sensemaking language of gestures that we acquire as babies long before we can speak concepts to the singular fuel that time in nature provides for the brain’s most powerful associative network.

Paul distills this recalibration of understanding:

Thinking outside the brain means skillfully engaging entities external to our heads — the feelings and movements of our bodies, the physical spaces in which we learn and work, and the minds of the other people around us — drawing them into our own mental processes. By reaching beyond the brain to recruit these “extra-neural” resources, we are able to focus more intently, comprehend more deeply, and create more imaginatively — to entertain ideas that would be literally unthinkable by the brain alone.

Zentropy — A New Theory That Could Transform Material Science

The universe naturally gravitates towards disorder, and only through the input of energy can we combat this inevitable chaos. This idea is encapsulated in the concept of entropy, evident in everyday phenomena like ice melting, fires burning, and water boiling. However, zentropy theory introduces an additional layer to this understanding.

This theory was developed by a team led by Zi-Kui Liu, the distinguished Dorothy Pate Enright Professor of Materials Science and Engineering at Penn State. The “Z” in zentropy is derived from the German term “Zustandssumm,” which translates to the “sum over states” of entropy.

Alternatively, Liu said, zentropy may be considered as a play on the term “zen” from Buddhism and entropy to gain insight on the nature of a system. The idea, Liu said, is to consider how entropy can occur over multiple scales within a system to help predict potential outcomes of the system when influenced by its surroundings.

SLAC fires up the world’s most powerful X-ray laser: LCLS-II ushers in a new era of science

The newly upgraded Linac Coherent Light Source (LCLS) X-ray free-electron laser (XFEL) at the Department of Energy’s SLAC National Accelerator Laboratory successfully produced its first X-rays, and researchers around the world are already lined up to kick off an ambitious science program.

The upgrade, called LCLS-II, creates unparalleled capabilities that will usher in a new era in research with X-rays.

Scientists will be able to examine the details of quantum materials with unprecedented resolution to drive new forms of computing and communications; reveal unpredictable and fleeting chemical events to teach us how to create more sustainable industries and ; study how carry out life’s functions to develop new types of pharmaceuticals; and study the world on the fastest timescales to open up entirely new fields of scientific investigation.

Post-Science Civilizations

For centuries now science has unlocked ever more mysteries, but could we one day run out of discoveries or abandon further research?
