...sophisticated scientific analysis has raised questions about the authenticity of three paintings attributed to Jackson Pollock, Harvard researchers reported this week. But the canvasses are still slated to go up for exhibition at Boston College this fall. Using scanning electron microscopy, Raman spectroscopy, and a slew of other state-of-the-art techniques, scholars at the Harvard University Art Museums found materials in the paintings that were not available until years after Pollock died. The analysis revealed that one of the three paintings includes a brown pigment that was not created until the early 1980s and not available...
Leverett Professor of Physics Gerald Gabrielse and his team recently advanced one of the major theories in phsyics by measuring the magnetic moment (G-factor) of an electron to a precision an order of magnitude higher than previous measurements, confirming that an electron has no internal structure and is, indeed, a fundamental particle...
...breakthrough that allowed for this new precision include a new technique to cool an electron until it reached its quantum-mechanical ground state, according to physics graduate student David A. Hanneke, who co-authored the paper. The researchers then carefully controlled the planar and axial motions of the electron through a combination of electric and magnetic forces to measure precisely the frequency responses of the electron...
Hilbert responded kindly and quite generously the following day, claiming no priority for himself. "If I could calculate as rapidly as you," he wrote, "in my equations the electron would have to capitulate and the hydrogen atom would have to produce its note of apology about why it does not radiate." Yet one day later, Hilbert sent a paper to a scientific journal with his own version of the equations for general relativity. The title he picked for his piece was not a modest one. "The Foundations of Physics," he called...

A Lowell House student tried to find out how a fridge worked, ruptured the machine’s gas pipe and had to be rescued by the fire department. 4/23: Harvard, MIT get largest electron accelerator in the world. Costing $6.5 million, the project will be completed by 1960. 5/7: Robert B. Woodward, Loeb professor of chemistry, synthesized reserpine, an important drug in the treatment of mental disorders.
