Smart materials are designed materials that have one or more properties that can be significantly changed in a controlled fashion by external stimuli, such as stress, temperature, moisture, pH, electric or magnetic fields.
Famous quotes containing the words smart and/or materials:
“Glorious the northern lights astream;
Glorious the song, when God’s the theme
Glorious the thunder’s roar:
Glorious hosanna from the den;
Glorious the catholic amen;
Glorious the martyr’s gore:
Glorious—more glorious is the crown
Of him that brought salvation down
By meekness, called thy Son;
Thou that stupendous truth believed,
And now the matchless deed’s achieved,
Determined, Dared, and Done.”
—Christopher Smart (1722–1771)
“Young children learn in a different manner from that of older children and adults, yet we can teach them many things if we adapt our materials and mode of instruction to their level of ability. But we miseducate young children when we assume that their learning abilities are comparable to those of older children and that they can be taught with materials and with the same instructional procedures appropriate to school-age children.”
—David Elkind (20th century)
