Mathematical Constants
Intriguing, ubiquitous, and at times mysterious, numerical constants set the allowable limits for all universal phenomena. Whether your questions involves π, Avogadro's number, Planck's constant, the atomic mass unit, or any of the other multitudes of immutable numbers used in science, this is the category where they should be asked.

-2 and 2 are opposites as they lie on opposite side of 0 on number line. They are equal distance from 0 in different directions.
What is the fractional equivalent of the approximation of pi?
That depends on how precise you want the approximation.
What is the value for Stefan's constant?
The value of the constant, better known as the Stefan–Boltzmann constant is given, in SI units by
σ = 5.670373×10^−8 W m^−2 K^−4
W = Watts
m = metres
K = Kelvin
How is the refractive index of one medium with respect to the otherrelated to the speed of light?
The refractive index of any substance is
(speed of light in vacuum)/(speed of light in that substance) .
The number is greater than ' 1 ' in any material medium.
There are many occurrences of the Golden Ratio in nature, such as the arrangement of branches on plant stems or veins on plant leaves; skeletons of animals and their cario and nervous systems; proprotions of chemical compounds and geometry of crystals; the spiral of snail shells; and the proportions of face and body that we find most 'attractive'.
(a+b)/a = a/b = 1 + √5 = 1.6180339887498948482...
Graham's number is the upper bound of solutions to a certain equation in Ramsey
Theory. It is unimaginably larger than a googolplex. If you were to write it as an
ordinary decimal number, with digits the size of an atom, there wouldn't be enough
room in the observable universe to hold it. But the end of it is ...2,464,195,387.
You can find several nice detailed discussions of it if you do a web search
for "Graham's number".
What numbers are in the 74th and 75th decimal place?
How many digits are there in pi that you have found?
I found a million, but ten trillion have been calculated. The operation took 350 days, and was performed in base 16, taking an extra 10 days or so to convert to base 10.The first million can be found in the related link.
What is the speed of blue colour light in vacuum?
blue light is an ELECTROMAGNETIC WAVE.ALL THE EM WAVES HAVE THE VELOCITY
3*10^8M/S IN VACUUM.Hence the blue also..
Atomic mass differnet from the atomic mass number why is that?
The atomic mass is an average, allowing for the relative abundances of different isotopes.
No
To be divisible by 6 a number must be divisible by two and 6289 is odd
Why is the median so important?
It is NOT so important!
Its importance, such as it is, derives from the fact that it is relatively easy to compute and is not affected by outliers. However, it cannot be used for data which are qualitative and, even where it can be used, almost all the information in the data set is discarded which leaves a very low information content.
