Famous quotes containing the words interesting and/or properties:
“PLAYING SHOULD BE FUN! In our great eagerness to teach our children we studiously look for educational toys, games with built-in lessons, books with a message. Often these tools are less interesting and stimulating than the childs natural curiosity and playfulness. Play is by its very nature educational. And it should be pleasurable. When the fun goes out of play, most often so does the learning.”
—Joanne E. Oppenheim (20th century)
“A drop of water has the properties of the sea, but cannot exhibit a storm. There is beauty of a concert, as well as of a flute; strength of a host, as well as of a hero.”
—Ralph Waldo Emerson (18031882)
