Three Scientists

Three scientist went on a discovery tour to the sea, a biologist, a physicist and a chemist. Reaching the sea, a very big ugly fish swam to the shore and then swim back into the deep sea. The Biologist said he needs to find out the phylum to which the fish belongs so he dives into the sea.

After a long time, his friends didn't see any sign of him, the physicist said he must have been carried away by the waves, he therefore decided to go in and measure the wavelength and frequency of the wave so that they can be able to locate the location of the biologist. He went in and disappeared.

After a long period of waiting, the chemist started going home. A man nearby watching the drama stopped him and asked, "Why should you just walk away when two friends of yours are drowning in the sea?"

The Chemist replied, "We just came for discovery and I have discovered something; both of them are soluble in water."
