Literary and artistic naturalism aims at accuracy and objectivity and cultivates realistic and even sordid portrayals of people and their environment. Philosophical naturalism, which is often identified with materialism, holds that minds, spirits, and ideas are fundamentally material.
For the stiffness to weight ratio, see specific modulus. The specific strength is a material's strength (force per unit area at failure) divided by its density. It is also known as the strength-to-weight ratio or strength/weight ratio. In fiber or textile applications, tenacity is the usual measure of specific strength. The SI unit for specific strength is Pa /(kg / m 3), or N Â·m/kg, which is dimensionally equivalent to m 2 /s 2, though the latter form is rarely used.
Ratio and proportion are two geometric principles used by medical professionals on a daily basis, allowing them to compare two quantities and calculate the results. If a physician writes an order for 10 mg of medication for every 10 pounds of body weight, the nurse would have to calculate the proper dosage.
