The relationship between a main sequence star's b-v color value and luminosity is a direct relationship.

The Hipparcos satellite measures the distances between hundreds of thousands of stars. It measures the magnitude of each stars through two filters which are, a blue filter, yielding for B magnitude (for blue) and a greenish filter, yielding a V magnitude (for visual).

The difference between the B and V magnitude of star is (B-V) color , or sometimes just "color" in short. The wavelength of light where the star is related to the star's temperature, i.e., the hotter the star the more blue it is and the cooler the star the more red it is.

the population of Chicago is about 3,000,000. how does that compare to the total number of dead and wounded in World War 1? ( in
ivanzaharov [21]
During World War I, 116,516 US soldiers were killed and 204,002 were wounded. If you add those two numbers together, the total number of US soldiers killed or wounded was 320,518.

You can represent that as a fraction of the current population of Chicago like this:

\frac{320,518 soldiers}{3,000,000 Chicagoans}

For simplicity's sake (since I assume the Chicago population number is an estimate), let's round the number of soldiers killed or wounded down to 300,000. That would look like this:

\frac{300,000 soldiers}{3,000,000 Chicagoans}

We can simplify that down a lot by dividing the number of soldiers and the number of Chicagoans by the least common denominator of 300,000. That would give us this fraction:

\frac{1 soldier}{10 Chicagoans}

So for every 1 US soldier killed or wounded in World War I, there are 10 Chicagoans living in the city today.
