| A idle boat at the entrance of Ilsan beach |
Today I visited Ilsan beach located in the south of the Republic of Korea, the atmosphere was soothing with a beautiful ambiance. I was passing through the coast and taking the pictures of surroundings. I notice two important phenomena quite familiar in Soft Matter Physics - (i) granular dilation and (ii) Hydrodynamic instability.

| Ripples on the surface of the sand in the beach (hydrodynamic instability) |

| Human foot mark on the surface of the sand in the beach (Granular dilation) |
I was amazed, though I went to sea beaches several times but never experience such joy. In granular physics, researchers are trying to understand the shear-induced expansion of granular material and the formation of ripples due to the granular flow. These serene observations are wonderful source of a quest for the researchers. Finally, I was also able to visualize the natural phenomenon that is well documented in the literature of Physics.
