Any of the more important scientific creations and inventions in history are inseparable from the creator's independent and in-depth approach to looking at problems. ——Hua Luogeng, mathematician Imagination is more important than knowledge, because knowledge is limited, and imagination summarizes everything in the world, promotes progress, and is the source of knowledge evolution. Strictly speaking, imagination is a real factor in scientific research. ——Einstein, American physicist Thinkers help people think because they set the way for others to think. No one can write or think alone behind closed doors - thinking is invisible, but in order to create something tangible and contemporary, it is necessary to express thoughts. —— Hubbard, American humorist Laziness in thinking, unwillingness to delve into and understand deeply, complacency or contentment with trivial knowledge are all causes of intellectual poverty.
