Today is National Weed Appreciation Day in USA! Appreciate your Weed!
Why did the dandelion become a motivational speaker?
Because it wanted to teach everyone how to turn their weeds into wishes!
Why was the clover invited to the garden party?
Because it was a popu-lawn guest!
Isidor TraubeDied 27 Oct 1943 at age 83 (born 31 Mar 1860).German physical chemist who founded capillary chemistry and whose research on liquids advanced knowledge of critical temperature (the point at which liquid and gas states of a substance are identical), osmosis, surface tension and colloids (suspensions of nanometer-sized particles). He studied liquids including gastric juice, urine, blood, and milk. He designed a viscometer to measure viscosity and a capillarimeter to measure capillary action, the rise of a liquid in a narrow tube. In 1891 he made what could be the first systematic observation of what is now commonly known as the hydrophobic effect. (A single molecular layer of a surfactant adsorbed to a planar liquid-vapour interface does so with hydrocarbon "tails" protruding.) |
