Affine curve of an absolutely irreducible polynomial
Let $f \in F_{q} [X, Y]$ be an absolutely irreducible polynomial of degree n. Denote the affine curve defined by the equation $f (X, Y) = 0$ over $F_{q}$ by $Γ (F_{q})$ , and let $d = \deg Γ$ . The for each m there exists $q_{0}$ such that $| Γ (F_{q}) | \geq m$ for all $q \geq q_{0}$ .

How to write Kelvin equation in a different way
My question is about the Kelvin equation which is as follows:
$\ln (e / e_{s}) = \frac{2 \cdot σ}{n \cdot k \cdot T \cdot r}$
Keep in mind that the $e$ in $\ln (e / e_{s})$ is not the constant $e$ .
I know that:
$\frac{e}{e_{s}} = e^{(\frac{2 \cdot σ}{n \cdot k \cdot T \cdot r})}$
I need to show that this is equal to:
$\frac{e}{e_{s}} = 1 + \frac{a}{r}$
Where $a = \frac{2 \cdot σ}{n \cdot k \cdot T}$
How do I go about doing this?
