The scale does depend on cosmological parameters like the baryon and matter densities, and the number of neutrinos, so distances based on BAO are more dependent on cosmological model than those based on local measurements. Light echos can be also used as standard rulers, [27] [28] although it is challenging to correctly measure the source geometry.
A star prime is a star number that is prime. The first few star primes (sequence A083577 in the OEIS) are 13, 37, 73, 181, 337, 433, 541, 661, 937. A superstar prime is a star prime whose prime index is also a star number. The first two such numbers are 661 and 1750255921. A reverse superstar prime is a star number whose index is a star prime ...

Number the stars is partly focused in the friendship of two 10-year old girls but it's really about the struggle of the Danes in rescuing the jews from being 'relocated'(killed) by the Nazis. it's also good for adults.
The modern scale was mathematically defined to closely match this historical system by Norman Pogson in 1856. The scale is reverse logarithmic: the brighter an object is, the lower its magnitude number. A difference of 1.0 in magnitude corresponds to the brightness ratio of , or about 2.512. For example, a magnitude 2.0 star is 2.512 times as ...
