Heritability lost; intelligence found
Probably nothing makes human beings more different from other species—and from one another— than their intelligence. The subject is of profound general interest—what the brain is for and how it works, the distinctiveness of the human mind, what makes us individual and human—yet delivers so little. Human intelligence remains poorly defined and characterized, even among those who most study it. R...
متن کاملLost - and found - in translation.
Valued colleagues and friends, thank you for the extraordinary privilege of serving as the 101st ASCI president. To stand before this distinguished group of physician-scientists without a PowerPoint presentation full of data slides is a deeply uncomfortable position. I do not stand before you with the data of graphs, charts, and models, but rather with the data of experience acquired through a ...
متن کاملSaturn's spokes: lost and found.
The spokes are intermittently appearing radial markings in Saturn's B ring that are believed to form when micrometer-sized dust particles are levitated above the ring by electrostatic forces. First observed by the Voyagers, the spokes disappeared from October 1998 until September 2005, when the Cassini spacecraft saw them reappear. The trajectories of the charged dust particles comprising the s...
متن کاملPlanck-length Phenomenology
This author's recent proposal of interferometric tests of Planck-scale-related properties of space-time is here revisited from a strictly phenomenological viewpoint. The results announced previously are rederived using elementary dimensional considerations. The dimensional analysis is then extended to the other two classes of experiments (observations of neutral kaons at particle accelerators a...
متن کاملPlanck Length and Cosmology
We show that an unification of quantum mechanics and general relativity implies that there is a fundamental length in Nature in the sense that no operational procedure would be able to measure distances shorter than the Planck length. Furthermore we give an explicit realization of an old proposal by Anderson and Finkelstein who argued that a fundamental length in nature implies unimodular gravi...
