A comparison of the masses
for these weights for the 1965, 1971, and 1989 determinations is shown in Fig.
McArthur says that the team expects over the next year to ferret out the masses
of several other planets from existing Hubble data.
We want to bring biometrics to the masses
so the world will know you as you are.
Other techniques described last month, while more speculative, may eventually enable astronomers to measure the masses
of black holes going back to the era when galaxies first formed.
Another six stars require further study before the masses
of their companions can be accurately measured.
Both theory and experiment so far suggest that any neutrino masses would be so peculiarly small as to be far out of line with the masses
of all other forms of matter.
But the standard model of fundamental particles and interactions says nothing directly about the masses of quarks and leptons.
Theorists have proposed that the masses of the fundamental particles depend on how strongly each type of particle interacts with a hypothetical entity called the Higgs field, which permeates the otherwise empty vacuum of space.
knowing the masses
of binary neutron stars will prove invaluable for analyzing observations with a set of gravitational wave detectors now under construction.
Although we don't have a good [theoretical] understanding of what any of the masses
of the fundamental constituents are," says Chris Quigg, also of Fermilab, "the top is now so much heavier than any of the others.
The new technique measures the masses
of huge protein molecules far more swiftly, accurately and easily than gel electrophoresis, the standard method for such analyses, say chemists Brian T.
It fails, for example, to specify why the various elementary particles of matter have the masses they do, and why these particles fall into exactly three families.
And particle physicists are pushing forward their search for the still-undiscovered top quark and a fifth force of nature required by the standard model to determine the masses of the elementary particles.
My view is that the masses
of stars are related to, if not determined by, the properties of the clouds out of which stars form.
The experiment concerns one of the foundation principles of the theory, Einstein's idea of the masses
of material objects.
