what are the universal constants? is pi such a constant?

Answer 1

bohr = 0.529177249 angstroms
atomic mass unit = 1.6605402 x 10 -27 kg
electron charge = 1.602188 x 10 -19 C
Planck's constant (h) = 6.6260755 x 10 -34 J s
Avogadro's number = 6.0221367 x 10 23
calorie = 4.184 J
hartree = 4.3597482 x 10 -18 J
Speed of light (c) = 2.99792458 x 10 10 cm / s
Boltzmann's constant (K) =1.380658 x 10 -23 joule/degree

The mathematical constant π (pi) is a real number, approximately equal to 3.14159, which is the ratio of a circle's circumference to its diameter in Euclidean geometry, and has many uses in mathematics, physics, and engineering. It is also known as Archimedes' constant (not to be confused with Archimedes number) and as Ludolph's number. but I guess it is not considered as one of the universal constants.

Answer 2

No , just because pi is an irrational number , dose not mean that it is not constant . A circle is a circle and pi is pi . U know pi as ..
3.14159 . Your math teacher isn't going to tell you that pi = 1.3246 any time soon . Cuz , u know it's constant .The only thing that is is different is it's level of approximation .

Answer 3

pi is a constant, since its value doesn't change (it doesn't matter than it can't be fully written, just like 1/3 = 0.3333 repeating). Other constants are: gravity (big G), e, ln (natural log), planke's constant as mentioned above (h). There are lots of constants.

Answer 4

the 20 in a square root is constant. Pi is not yet a constant, we'll find out later.

Answer 5

universal constants are numerical constants that will not change with time or space.

Answer 6

universal constant is Plank'constant that the amount of it has been determined. pi has not determined exactly.

Answer 7

women will always change their mind
men will always be horny
children will always say the most inappropriate things
knowledge is infinite
no system is both complex and complete
we'll never know if we've discovered the most elegant algorithm to a solution (Turing's Entscheidungsproblem)
