Time dilation and time travel have always fascinated me since I watched Carl Sagans Cosmos as a kid but as I tried to better understand it a couple of things about the formula to calculate the amount of time dilation have always bothered me.Simply...

The coefficient of friction is a dimensionless scalar value which describes the ratio of the force of friction between two bodies and the force pressing them together.The coefficient of friction between the tires of a car and the road varies depending on the road...

The best forms of energy use are functions of how energy is used. Intellectual energy is of the highest priority. A lethargic nation intellectually will create far more problems that were avoidable than it needed to. Those who forget the future are doomed to repeat...

A distracted driver will have a greater reaction time than a non-distracted driver. A distraction to a driver will increase the drivers' reaction time and reduces the ability to respond to an emergency situation. The driver takes longer to react and more time passes between...

There are two main types of momentum: linear and angular.Linear momentum (p), which is primarily used for determining velocities in collisions because the linear momentum is always conserved, is most typically defined to be the product between the mass of an object and its...
Why and how absolute zero is -273.15 Celsius
By: Joel Toutloff
The temperature where all molecular motion has stopped is referred to as absolute zero, and it is considered as the lowest possible temperature ergo "absolute". Despite what the article title reads, absolute zero is at zero Kelvin, making the Kelvin scale an absolute temperature scale...

In order for the energy requirements of the future to be met, an unprecedented development of new energy harvesting technologies to replace simple exothermic oxidation is absolutely essential. An imminent large-scale development and implementation of new energy harvesting technologies is vital for a number of...

Entropy is a concept in thermodynamics. It measures heat loss. When any process happens in a physical system, energy is dissipated. When you drive a car, the engine doesn't just produce forward motion, but also noise and heat. This noise and heat is useless energy...

When I became involved in the nuclear waste issue in 1980, the Concerned Citizens of Manitoba (CCM), attempted to locate scientists in a variety of disciplines who could help us in our effort to gather and analyze information to deal with the underground radioactive waste...

If string theory is the ultimate, we are stuck with a number of unknowns in ten dimensions. This writer is of the opinion that we can develop a simpler, easier to understand model by the use of a little logic. Step one. Find an alternative...
