This expression is used in Carbon dating.
ln (Nf/No) is the natural logarithm of the percent carbon-14 in the sample (Nf),compared to the percent carbon-14 in living tissue (No), and t1/2 = the half-life of carbon-14 = 5,700 years.
After the {[ln (Nf/No) / (-0.693)] * t1/2 } is worked out, it gives how old the sample or fossil is.

Yes. It means divide the value of Nf by the value of No, take the natural logarithm of that quotient, divide it by -0.693, and multiply that result by the square root of the value of t.

to get things started
ln means natural log ie log to base e
e approx = 2.718

That math is hard.
