 String Theory and String Rotation

## Strings

An elaborate theory has been developed that elemental particles such as quarks and leptons are very small strings, which may be open or closed.

## Do they rotate? Do they ever!

From the work of Aage* Bohr and Dan Mottelson we have that at the nuclear level the angular momentum of a structure is quantized according to the formula

#### Jω = h(I(I+1))½

where J is the moment of inertia of the structure, ω is its rate of rotation, h is Planck's constant divided by 2π and I is a positive integer.

The moment of inertia of a circular closed ring of radius r and mass m rotating like a wheel is mr². The moment of inertia for a closed ring rotating like a flipping coin is same as that of the ring rotating as a wheel.

The masses of the up and down quarks are estimated to 1/470 and 1/296 of the mass of a proton, respectively

#### mup = 1.673×10-27/470 = 3.56×10-30 kg r = 2×10-16 Jup = 3.56×10-30(2×10-16)² = 1.4242×10-61 kg m²

Therefore the minimum rate of rotation is given by

#### ω = h(2)½/Jup = (1.05457×10-34)√2/1.4242×10-61 = 1.05×1028 per second

A ring rotating this fast through spinning and flipping motion would have the appearance and effect of a spherical shell.

The Danish name Aage is properly pronounce like the English word owe with a slight eh at the end. This is because the proper spelling of this name in Danish is Åge. The letter å has the sound oh.
