Semiconductors - Inversion Layer Capacitance -
 - flashG (66)     The essence of this paper is to argue that in a semiconductor a precise equality exists between the bulk capacitance and inversion-layer capacitance at the threshold voltage. To start, the semiconductor threshold condition is defined as that for which surface potential is equal in magnitude... ( added 16 days 7 hours ago.) |

Black Holes, Super Colliders And The Bible -
- Joel Hendon (4,368)     Joel Hendon  Black Holes, dark energy, big bangs, and the like are ideas which come into scientific minds when they don't have a clue what is causing, whatever they see happening. I'm sure that the wheels in many of their brains become so absorbed with these phenomena that they lose lots of sleep at night.... ( added 33 days 18 hours ago.) |

Super Collider Extraordinary, Doomsday Machine? -
- Joel Hendon (4,368) Joel Hendon My limited knowledge of physics causes me to rely greatly on others with much greater knowledge. Studies of atom splitting and atom fusing has been going on for almost a century now. It was such a tedious and complex study that it took years of ingenious mathematical computations to master the... ( added 47 days 19 hours ago.) |

What is Gravity and Why Does it Work? -
Burt Jordaan (22)   Burt Jordaan Even today, gravity is still a mysterious force, if it is a force at all. We all know the effects of gravity and how difficult it is to work against it. Think about climbing a long staircase. What is it that tries to pull you down? Obviously it is the mass of Earth, but how does mass accomplish... ( added 303 days 1 hour ago.) |

Some Like it Hot - Some Like Physics, how Come? -
Thomas Oestereich (48)  Thomas Oestereich If you think about it, physics is at the root of many human activities. Nevertheless, it is obvious that the majority of people don't like it and keep away, actually: This seems to be the normal way to feel towards this subject. This includes many people who usually are very motivated to get... ( added 1 year 135 days ago.) |

E=mc2 is Wrong - Einstein's Special Relativity Fundamentally Flawed -
mike strauss (73) In 1905, Albert Einstein published 'On the Electrodynamics of Moving Bodies' now known as Special Relativity this theory revolutionized geometry, math, physics, science and the classical perspective of the universe as understood since Newton's time. However, were there intrinsic errors in... ( added 2 years 161 days ago.) |

Methods of Improving Boiler Efficiency -
Thomas Yoon (4,594)  Thomas Yoon With the rising cost of fuel prices, industries that use steam boilers for heating or power generation are hard pressed to operate at peak efficiencies. While steam consumption, leakages, and other heat transmission losses can contribute to the overall energy bill, this article focuses on the... ( added 2 years 303 days ago.) |

Biophysics: Advanced Knowledge Absorption Techniques -
Jim Ray (92) As humanity and its understanding of inter-conscious existence continue to evolve, so does the mind’s capacity to interpret a greater understanding of its overall capability, both collectively and individually. Broader access to central knowledge resources such as the Internet, libraries, and... ( added 2 years 318 days ago.) |

Perpetual Motion versus Pollution -
Tommy (20) Pollution is a topical subject, not least because of the effects of climate change and the US’s refusal to sign up to the Kyoto treaty. It doesn’t take a rocket scientist to work out that if our planet is to remain habitable, we cannot continue burning fossil fuels at the rate we are. An... ( added 2 years 322 days ago.) |

Sophus’ choice: Redefining the role of Ancient Greek scholars in modern society -
altspace (328) It is known by most high school students that Ancient Greek scholars were very adept in philosophy (from ‘ philos ’ and ‘ sophos ’), math (geometry), debates, and music. They depicted the universe as a set of harmonious arrangement of circles (the most idealistic shape in their mind). ( added 3 years 142 days ago.) |

Transducers -
Thomas Yoon (4,594) Thomas Yoon Complex control systems all make use of signals that can be easily measured and altered remotely. Automatically operated machines or actuators need to be powered either by electrical motors, pneumatic or hydraulic cylinders. The most common signals sent out from a transducer are electrical...

Cooling Towers - Workhorses of Industries -
Thomas Yoon (4,594) Thomas Yoon Industrial Processes usually produces a lot of heat. Air-conditioning also removes heat from the indoor areas through heat exchangers. Where does all the heat go? All these heat has to be removed. If you are not near the sea, you have to use cooling towers to cool down your warm water. ... ( added 3 years 165 days ago.) |

Boiler Water Chemical Treatment -
Thomas Yoon (4,594) Thomas Yoon A boiler is used for generating steam. It does this by heating water to its boiling point, after which steam will evaporate from it. When you boil a kettle of water, you will shut off the fire or electric power when the water comes to a boil. No so with a steam boiler. Generation of steam... ( added 3 years 165 days ago.) |

Boiler Manhole Safety -
Thomas Yoon (4,594) Thomas Yoon Boiler inspections are necessary in order to find out the effectiveness of the boiler water chemical treatment. It is also useful to detect any faults or potential weakness in the steel structures, plates and shells so that accidents can be avoided. However, even entering the boiler for...

Boiler Inspection -
Thomas Yoon (4,594) Thomas Yoon A steam boiler is a pressure vessel with a difference. The vessel is subjected to heat stress of expansion and contraction, internal and external corrosion, as well as intense heating on some of its surfaces. If we are not careful, the steam pressure can rise up very high, and it can become a... ( added 3 years 165 days ago.) |

Evaporator -
Thomas Yoon (4,594) Thomas Yoon Evaporator coils of air conditioning systems are sometimes called cooling coils. But cooling coils are also used in air-handling units. These contain chilled water. These are completely different from those used in direct expansion air cond units. So cooling coils is not an accurate word to... ( added 3 years 165 days ago.) |

In the beginning -
Ben Morrish (700)   Ben Morrish In the Beginning there was the Universe. Before that time didn't exist so "before that" doesn't have any meaning. The universe consisted of simple rules, and energy which obeyed them (indeed the rules and the energy are the same thing in a sense, each can only exist with the other and each is...

The Invisible Ether and Michelson Morley -
mike strauss (73) Modern scientists adopted the ancient concept of the ether to explain the fundamental nature of the universe. Einstein allegedly dethroned the ether concept with his space time continuum. In spite of this, we might have to revisit the ether concept. The concept of the invisible ether or...
