alpha

At his heart is a gorgeous star of first magnitude, α or Regulus.

Certainly we must take the tan α at the maximum Ky value for minimum speed, as then the drift is the greatest (Fig. 1, A).

In addition to its regular name, α Urs Minoris is frequently called by the special name Polaris, or the pole star.

The total quantity of electricity carried by the α-particles emitted in one second is measured independently.

Let r be the radius of the torsion rod, l its length from the needle over ef to r, and α the observed torsion angle.
