Mathematical Database MATHEMATICAL INDUCTION 1. Introduction Mathematics distinguishes itself from the other sciences in that it is built upon a set of axioms and definitions‚ on which all subsequent theorems rely. All theorems can be derived‚ or proved‚ using the axioms and definitions‚ or using previously established theorems. By contrast‚ the theories in most other sciences‚ such as the Newtonian laws of motion in physics‚ are often built upon experimental evidence and can never be

AP Psychology February 11‚ 2013 FRQ: Stages The stage theories of J. Piaget‚ E. Erikson‚ and L. Kohlberg are fundamental in explaining how a person develops. In Piaget’s case he described cognitive development in four stages- sensorimotor‚ preoperational‚ concrete operational‚ and formal operational. In Piaget’s sensorimotor stage which is usually from birth to age 2‚ babies experience the world through their sensory and motor interactions with objects such as through looking‚ hearing‚ touching
