49 is the square of 7, which is a prime number.
It's the smallest discriminant of a 'totally real cubic field', which sounds sort of suspicious by insisting on its real-ness.
49 squared is 2401, and 2+4+0+1 is 7, which is the square root of 49. There doesn't appear to be a fancy name for that, but Wikipedia found it noteworthy.
It's the atomic number of Indium, which is used as a vacuum seal and thermal conductor in cryogenics.
49 is the code for International direct dial calls to Germany
The 49th parallel forms much of the border between the US and Canada

It's also how old I am today. :)

Congrats! (And Indium is also the most valuable metal in No Man's Sky, available only after you get your best star drive engine that allows you to visit blue stars.)
