The paper briefly reviews the progress in turbulence research in the20th century and a number of issues are addressed based on achievements.The mod-ern theory o
Both the velocity and temperature measurements taken in turbulent Rayleigh-B'enard convection experiments have been analyzed. It is found that both the velo
Recent experiments related to the Dragon Wash phenomena showedthat axisymmetric capillary waves appear first from excitation, and circumferentialcapillary waves
