Stars A star is a massive‚ luminous sphere of plasma held together by gravity. The nearest star to Earth is the Sun‚ which is the source of most of the energy on the planet. Solar System The Solar System consists of the Sun and its planetary system of eight planets‚ their moons‚ and other non-stellar objects. It formed 4.6 billion years ago from the gravitational collapse of a giant molecular cloud. The vast majority of the system’s mass is in the Sun‚ with most of the remaining mass contained

An Open Mind to an Open System AN OPEN MIND TO AN OPEN SYSTEM The Open System Theory was initially developed by Ludwig von Bertanlanffy (1956)‚ a biologist‚ but it was immediately applicable across all disciplines. It defines the concept of a system‚ where "all systems are characterized by an assemblage or combination of parts whose relations make them interdependent". As one moves from mechanical to organic and social systems‚ the interactions between parts in the system become more complex and

The Senses The sensory system involves hearing‚ touching‚ tasting‚ smelling‚ and seeing‚ which provide data for perception. The eye is a sensory organ held by an orbit that allows vision (a detection of light in a way that provides mental images of objects) and holds photoreceptors. Photoreceptors are used to absorb light energy‚ which are bent by a transparent unit called the lens. Some photoreceptors in the eye are the rod cell and cone cell. Rod cells are used in dim light for coarse images and

Family Systems Theory This theory emerged from General Systems Theory by scholars who found it had many applications to families and other social systems. Any system is defined as a bounded set of interrelated elements exhibiting coherent behavior as a trait. (Constantine‚ 1986). Another definition is an assemblage of objects related to each other by some regular interaction or interdependence (Webster). Families are considered systems because they are made up of interrelated elements or objectives
