2. In the Aug.99, issue of Discover Magazine pg.50 shows excellent picture=s =

(electron microscope)of cavitating bubbles and their destructive pot-mark=s =

made in metal surfaces. It also gives a good basic explanation of the pro=cess.

3. =

In the July 12th , 1999 issue of the periodical - Physical Review L=etters, =

Vol.83, #2, pg.440 is a study that was published entitled "Cluster Format=ion in =

a Granular Medium Fluidized by Vibrations in Low Gravity" it describes an= =

experiment done recently by French scientists. The experiment was designe=d and =

launched aboard a suborbital flight that only lasted for a little over 20=0 seconds. =

In a nutshell, it states that in a vibrated granular medium, motion=less =

eggshaped clusters form, surrounded by low particle regions. The experime=nt used =

several different freqs. and grain densitys. The grains used, were bronze= spheresof different diameters. This experiment proves the possibility that the suns' pulsing playe=d a part =

in the formation of the planets. It should be mentioned here, that the ac=tual shape =

of planet Earth and recently discovered that the planet Mars, has been de=scribed asthat of a slightly pear or eggshaped, not a perfect sphere! =
