The hyperloop is a revolutionary mode of transportation that combines vacuum tubes and magnetic levitation technology to achieve ultra-high-speed travel. Just like in the movies, it promises to allow people to travel long distances in a short amount of time, but there are still many technical challenges to overcome before commercialization.   We are living in an era where the imaginary...

Respiration plays an important role in maintaining life by regulating the balance of oxygen and carbon dioxide in the body.   What are the characteristics of life that are common to all animals? One of...

This article explains how wave motion is modified in shallow water by deriving the speed of travel of a wave through the variables amplitude, horizontal distance, and wavelength, and analyzing the acceleration and velocity patterns of water particles.   We’ll derive the speed of travel of a wave through three variables: amplitude, horizontal distance, and wavelength. Before we get...

The case of a boy with a low IQ who became proficient in multiple foreign languages and studies of people with aphasia confirm that human language ability exists independently of other cognitive abilities and is determined by specific areas of the brain. This shows that language is a distinct function of the brain.   A 13-year-old boy with an IQ of less than 70 cannot button his own clothes...
