The Latin poet Titus Lucretius Caro (I century B.C.), speaking of the origins of music in his work De rerum natura, expresses an interesting opinion on the scientific and technological progress that man has attained over the course of time.

  According to the Titus-Bode law, orbits of planets in the solar system obey a geometric progression. Many investigations have been launched to improve this law. In this paper, we apply square and exponential models to planets of solar system, moons of planets, and some extra solar systems, and compare them with each other.

We will discuss recent results for the spin structure functions, with an emphasis on g2. High precision g2 data allows for tests of the Burkhardt–Cottingham sum rule, and is needed to consistently evaluate higher twist effects.
