Magnetic Field Cube
The following equation gives the volume accurate to about 1 part in 70,000, equivalent to 0.1 °C:
V(ml./gr.) = 0.073554 + 0.000013245 * T + 1.22823*10-9 * T2
The volume (or density) versus temperature is something many of us use daily since it is the basis of mercury thermometry. You will note that the volume equation is nearly linear, as is usually assumed in Hg thermometer calibration.

'The strength and weakness of physicists is that we believe in what we can measure. And if we can't measure it, then we say it probably doesn't exist. And that closes us off to an enormous amount of phenomena that we may not be able to measure because they only happened once. For example, the Big Bang. ... That's one reason why they scoffed at higher dimensions for so many years. Now we realize that there's no alternative... '
