The Difference Between Being Intelligent And Being Wise

Intelligent : • wise, cunning, capable of thinking and reason Wisdom: • The state of being wise • Ability to use knowledge and / or experience wisely • Able to determine what is wise against what is unwise • A saying, a philosophy or other advice considered wise In Short: An intelligent man has a whole sea of knowledge and knows every fact. On the other hand, a wise man does not have all the knowledge that an intelligent man has, but he has the brain to know when to use knowledge. I have seen a lot of smart people make really stupid decisions. I was one of those people! The information I had before and after these decisions has not changed. But with every wrong decision, if I was willing to learn, my level of wisdom changed. The main difference is that: A smart or intelligent person knows how to solve any problem. A wise person knows how to avoid this problem. Knowledge makes a person intelligent. Experience makes a person wise.

Silt

Silt is granular material of a size somewhere between sand and clay, whose mineral origin is quartz and feldspar. Silt may occur as a soil or as sediment mixed in suspension with water (also known as a suspended load) in a body of water such as a river. It may also exist as soil deposited at the bottom of a water body. Silt has a moderate specific area with a typically non-sticky, plastic feel. Silt usually has a floury feel when dry, and a slippery feel when wet. Silt can be visually observed with a hand lens. Sources:- Silt is created by a variety of physical processes capable of splitting the generally sand-sized quartz crystals of primary rocks by exploiting deficiencies in their lattice. These involve chemical weathering of rock and regolith, and a number of physical weathering processes such as frost shattering and haloclasty. The main process is abrasion through transport, including fluvial comminution, aeolian attrition and glacial grinding. It is in semi-arid envir...
