We have a use case for this in pgRouting.
Basically we compute the driving distance of a network and get a

3. The entropy change, ΔS, associated with the isothermal (i.e.
constant temperature) change in volume of n moles of an ideal
gas from volume V1 to volume V2 is given by the equation
ΔS = nR ln(V2/V1)
where R is the gas constant.

I am wondering how to find the minimal polynomial of 2+\sqrt{i} over \mathbb{Q}.
I have got it to x^{4}-2x^{2}+9 but I don't know how to shaw that this is irreducible!
I don't know from where did you get that polynomial. I got:

ok, if we start with an equal triangle number 1 with short sides 2m. Then the long side is 2.8m. That then becomes one of triangle number 2's short sides.so triangle number 2s long side is 4m. that

Local data for elliptic curves over number fields
