Harvey L. Berger
Harvey Berger (August 30, 1938 – August 2007) was a scientist and inventor. He invented the modern commercial ultrasonic nozzle, which in its application has brought many benefits to the fields of research, combustion and manufacturing. Berger founded Sono-Tek Corporation based on this technology and while working at the company he made contributions to the fields of combustion, semiconductor manufacturing, electronic printed circuit board manufacturing, drug eluting stents and spray drying. Berger died in August 2007 after a struggle with liver cancer. He was survived by his wife Donna and by his three children, Michael, Robyn and Barbara. Early life and education Harvey Berger was born on August 30, 1938, in Brooklyn, New York. His parents were Regina Landow and Bernard Berger, a local pharmacist. His family later moved into the Hudson Valley region in mid-state New York. Berger earned a degree in Nuclear physics from Rensselaer Polytechnic Institute in 1960. During th ...

Capillary Wave
A capillary wave is a wave traveling along the phase boundary of a fluid, whose dynamics and phase velocity are dominated by the effects of surface tension. Capillary waves are common in nature, and are often referred to as ripples. The wavelength of capillary waves on water is typically less than a few centimeters, with a phase speed in excess of 0.2–0.3 meter/second. A longer wavelength on a fluid interface will result in gravity–capillary waves which are influenced by both the effects of surface tension and gravity, as well as by fluid inertia. Ordinary gravity waves have a still longer wavelength. When generated by light wind in open water, a nautical name for them is cat's paw waves. Light breezes which stir up such small ripples are also sometimes referred to as cat's paws. On the open ocean, much larger ocean surface waves (seas and swells) may result from coalescence of smaller wind-caused ripple-waves. Dispersion relation The dispersion relation describes the ...
