Why and how absolute zero is -273.15 Celsius
By: Joel Stottlemire
Actually, absolute zero is -273.15 C not Kelvin. There is nothing colder than 0 Kelvin except perhaps a lawyers soul.I work for the government as a statistician. This can be difficult because govenment officials tend to view statistics as a sort of beehive...

The international inch is defined exactly as 25.4 mmAt one time an 'inch' was a imprecise measurement. Often each town or region would have its own version, an this itself would change from time to time. Measures were, and are, used in trade, and...

Time travel would be an amazing achievement for humanity and has been a fantasy for science fiction for a long time. Einstein's theory of relativity (1905) and experiments with atomic clocks has shown that forwards time travel is possible. The closer to the speed of...

What if sometime in the future a time travel device is somehow invented to travel back in time? It hasnt been invented so far. However, if it will be invented sometime in the future then someone would have gone back to the year 2007. So...

Gravity is in effect, the pull or attraction, one object has on another. The larger the mass and density, the greater the pull or attraction of the object. Distance is also an important factor with the effect gravity has on an object. Gravity is what...

To a curious mind, gravity is a curious phenomenon. The more one pays attention to it, the more fascinating and mysterious it becomes. Today, we have the advantage of having had great minds ponder the mystery and define what can be observed and inferred by...

In physics, one of the most fundamental ideas needed to understand the universe is that of force. Understanding this concept is the first step to begin understanding the more complex ideas in physics and also getting a handle on its immense power of prediction...

Moments in Science: PlanckIn 1982, Carl Morris (C.N. Morris, Natural Exponential Families With Quadratic Variance Functions, Annals of Statistics, Vol. 10, pp. 65 80, 1982) introduced to statistical science world a class of probability distribution functions having a special relation between the mean and...

Yes. I think that it may well be possible to characterize a "Black Hole," at least the very simplest one. In a recent publication it was noted that a model of the surface of "Black Holes" could only truly be explained if that surface...
Quantum Physics is Time Travel Theoretically Feasible
By: Alan Watson
There are two distinctly separate perceptions of time travel. Firstly, time travel by the human mind, which, as a reader of history well knows, is possible by means of our imagination. Secondly, the notion of physical transport' from one time to another, by means of...
