According to some, nanotechnology holds the promise of a future heaven on Earth: all Man's needs will be met and an idyllic paradise will ensue driven by wondrous machines the size of molecules.Others predict a hell of unprecedented proportions.Like all predictions, the truth...
How understanding chemistry can help you in daily life
By: Kevin J. Browne
I remember as a kid being very bored in chemistry class. A few experiments here and there and a mountain of equations somehow could not compel me to curiosity for molecules and chemical reactions. How unfortunate. The worst part is that my boredom was almost...

A reaction rate is simply the speed at which a reaction occurs. Chemical kinetics, the study of reaction rates, analyzes the five main factors that influence the rate of a chemical reaction: temperature, concentration, particle size, the nature of the reaction, and the presence of...

All solutions are made up of two elements – a solute and a solvent. The solute is solid matter, liquid or gas, and the solvent is liquid into which the solute is mixed. Solubility is, to put it very simply, the amount of a particular...

In school they teach the speed of sound is 1,126 feet per second. That is only part of the story and it is only partially true. The reason for this is that the speed of sound changes. The factors that effect the speed of...

A human's "reaction time" is the amount of time it takes for a person to respond to stimuli, or to perform simple reflexive functions. Reaction time is generally related to reflex, the involuntary movement in response to a stimuli. To slow a reflex is to...

Humans have always debated the possibility that we are not alone in this universe. While the concept of alien life on other planets may sound stupid to some, others find it intriguing and fascinating. Most people who believe in aliens are considered to be stupid...

The maximum amount of solute that can dissolve in a certain amount of solvent is know as solubility. The solubility of a solute is measured by the concentration of the solution - as more solute is being added, the solvent's concentration will increase, eventually becoming...

Reaction time is the period between any emergency or danger, and a person’s response to the situation. This brief period, which is usually a matter of seconds, can mean the difference between life and death, or serious injury.Factors that affect reaction time range...

It perhaps represents one of the greatest enigmas the human mind can ponder, at least in terms of a lot of minds that hang out on Helium.com. Is time travel possible? Ironically, it really is no mystery at all and the unequivocal answer is...
