Document Summary
Deductive reasoning is a logical process in which a conclusion is based on the concordance of multiple premises that are generally assumed to be true. Deductive reasoning is sometimes referred to as top-down logic. Inductive reasoning is a logical process in which multiple premises, all believed true or found true most of the time, are combined to obtain a specific conclusion. Inductive reasoning is often used in applications that involve prediction, forecasting, or behavior. To see an object light from the object must reach our eyes. Light must take time to reach us so we always see objects as they were in the past. We seen the moon as it was 1. 3 seconds ago. Mars 14 min on average (3-22 min depending on where we are on the orbits) The mars rover cannot be driven in real time. The speed of light is c= 300,000 km/s. Light year is the distance light travels in one year- about 10 trillion kilometers.
