beating the tyranny of the equation
Controls
Presets
The rocket equation grows delta-v only with the logarithm of the mass ratio, so a single stage hauling empty tanks all the way up is hopelessly inefficient. Staging drops dead weight along the way: each stage contributes ve·ln(mass ratio), and their sum easily clears the ~9.4 km/s needed for low Earth orbit.

Reaches LEO?yes
Governing equation
Reading this result: 2 stages at Isp 350s and mass ratio 4 each sum to 9.5 km/s — past the ~9.4 km/s LEO budget, since every stage adds ve·ln(ratio) after dropping dead weight.
