The tenth planet
By: Jason Sorrell
Those of us who have an interest in astronomy and astrology are aware of an accurate, though complex formula which predicts the presence and positions of planets in our solar system. It is based on the observed movements of bodies in space which we are...
Bernoulli's principle of lift
By: Harry Stevens
When was the last time that you travelled on an airplane? Last year? Last month? Last week? Whenever it was, you owe your plane ride to the principle developed by famous mathematician Daniel Bernoulli. The principle is appropriately called Bernoulli's Principle, and it relates the...
An overview about the chemical element Oxygen
By: Reynold Conger
Oxygen may be the most important element on Earth. Without Oxygen, there would be no life, no fire, no water and little decay.On the periodic table, Oxygen is atomic number 8 and has an atomic mass of 16. The nucleus consists 8 protons and...

H Cl and H 2 OMuriatic acid, or hydrochloric acid is found in dilute form in the human stomach. The betaine hydrochoride found in the human stomach can be 100,000 to 1 million times more acidic than water. It is a highly corrosive, mineral...
Would aliens look like us?
By: Darren Chau
There is only one Earth, one Homo sapiens, in all the cosmos after all, it is hard to believe that billions of evolutionary steps could be perfectly reproduced elsewhere. In that sense, our species is unique. But where does one draw the line between similarity...
Why Pluto is not a planet anymore
By: Laurel Kornfeld
Pluto IS a planet because unlike most objects in the Kuiper Belt, it has attained hydrostatic equilibrium, meaning it has enough self-gravity to have pulled itself into a round shape. When an object is large enough for this to happen, it becomes differentiated with core...
Noteworthy features of the solar system
By: Darren Chau
The Great Red Spot is a gigantic high-pressure system that is likely to have raged on Jupiter continuously for the past 340 years, ever since it was first observed by man. During this period it has fluctuated in both size and colour; its famous reddish...
The Big Bang Theory
By: R K vanderHoek
The "Big Bang Theory" describes a rapid initial and then slowed, but, now accelerating, continual cosmic expansion of our observable universe from a super, hyper, mega, giga, uber, very, very, very dense particle of energy-mass, about 13.7 billion years ago. This has been confirmed...
The discovery of helium
By: Sam Beever
Helium is colorless, odorless, and tasteless. It is inert, not reacting with any element, including itself, and so tiny that it is used to find microscopic leaks. How did we ever discover such an elusive element?Well, first we have to observe something that has...
Methane on Mars
By: Argann Argannon
The easiest explanation for methane is geology. However, when you look at the amount they found (minute at best), then biology is a better preliminary guess. Which is all it is on both sides of this argument at this point, a guess. Almost forty years...
