An old saying tells us that “the whole is greater than the sum of its parts”. A fancier way of saying this is with the term emergent properties, a term used in science, systems theory, philosophy, urban studies and even…
You probably know that magnets don’t stick to nonmetal materials such as wood, plastic, glass, cotton and wool, but you may not know that magnets don’t stick to all metals. In fact, most metals are not magnetic. TL;DR (Too Long;…

Calculating lighting load relies on a single equation, watts = volts x amps, described mathematically with the following relationship: (text{watts} = text{volts} times text{amps} implies P = V times I) where P is power (measured in watts), V is voltage…
A flood plain is a type of geological feature that results when a river periodically overflows its banks due to rainfall, snow melt, or other factors. Floodplains are initially formed due to the meandering course of a river that gradually…
Ethanol, or ethyl alcohol, and methanol, or methyl alcohol, are renewable fuel sources, made from plant-based materials ranging from corn and sugar cane to agricultural and timber waste. They are highly flammable and volatile substances. Outside of carefully controlled environments,…
Dinosaurs with long necks are part of the sauropod clade, a group of plant-eating dinosaurs. They tend to have elongated necks, thick legs and smaller heads. They used their necks to reach taller trees and plants, so they could eat…
The dinosaurs roamed the earth for more than 150 million years. The Mesozoic Era, lasting from about 252 MYA to 66 MYA, marks the time of the dinosaurs (i.e. archosaurian reptiles). Many other species that still exist in some form…
