$N =\underbrace{\overbrace{R}^{\approx10} \times \overbrace{f_p}^{\approx 1} \times \overbrace{n_e}^{\approx 0.2}}_{\sim 1} \times \underbrace{f_l \times f_i \times f_c \times L}_{?}$  We can then simplify the Drake equation and re-write it in it's "2014 form"  as: $N \approx f_l \times f_i \times f_c \times L$
