We Have Always Been . . . Cyborgs

philosophy of mathematics suited well the ‘‘general emphasisin later nineteenth-century mathematics on revisiting foundationalquestions’’ (p. 61). Pure geometry as it emerged from Frege, Paschand Hilbert, provided a diagram-free, purely sentential notion ofproof, which has lasted unto our own day.In the second, and greater, part of the book, Greaves traces outthe interre...

Been: Long-Lived Plasma Cells Induced by T What Is and What Should Always Have

We'll always have RNA.

My romance with RNA began in Paris at the age of 21. After four undergraduate years at Caltech and before going to graduate school at MIT, I somehow managed to spend a miraculous year in the city of light, where I worked in the laboratory of Marianne Grunberg-Manago. She had done a post-doc with Severa Ochoa at NYU, where she discovered the enzyme polynucleotide phosphorylase (PNPase). This was...

Have Pentaquark States Been Seen?

The status of the search for pentaquark baryon states is reviewed in light of new results from the first two dedicated experiments from CLAS at Jefferson Lab and of new analyses from several labs on the Θ + (1540). Evidence for and against the heavier pentaquark states, the Ξ(1862) and the Θ 0 c (3100) observed at CERN and at HERA, respectively, are also discussed. I conclude that the evidence ...

Have Orbitals Really Been Observed?

1492 Journal of Chemical Education • Vol. 77 No. 11 November 2000 • JChemEd.chem.wisc.edu The purpose of this article is to comment on the pedagogical ramifications of the recently claimed observation of d orbitals and the way in which these results were first announced and subsequently reported (1–6 ). Atomic orbitals—their use in writing electronic configurations and as a means of rationalizi...
