    Credit: NASA/CXC/MIT/F. Baganoff, R. Shcherbakov et al. How do you probe a supermassive black hole? Take a look at the pulsars that orbit it. These rapidly spinning neutron stars flash regular radio pulses, and in an upcoming issue of The Astrophysical Journal astronomers say that the timing of such pulses could provide a new understanding of the 4 million solar mass black hole at the center of the Milky Way.

    Pigeons can learn abstract numerical rules, a skill that scientists had believed only primates possessed. Although the birds may not be able to do higher math, their ability to reason numerically is likely something that a wide variety of species can do, too, researchers say.

Resistance « Teach. Brian. Teach. - 1 views

shared by John Burk on 31 Dec 11 - No Cached
  • Because of this, and despite the fact that it is common practice, it is sort of a mistake to find the resistance of a circuit element by plotting V vs I and finding the slope. Obviously, if the circuit element is non-ohmic it doesn’t make any sense to report a single R value. However, even if the circuit element can be nicely approximated by Ohm’s Law, it actually makes more sense to report the value of R as an average of all V/I ratios than it does to calculate the resistance by determining the slope of the best fit line.  This is especially the case if your best fit-line has a non-zero y-intercept.

    very interesting subtlety about the definition of resistance and finding R from a I-V plot.
