Physical Science

Computational chemistry is a branch of chemistry that deals with mathematical calculations that lead eventually to the determination of the energy and geometry of particular chemical compounds of interest to the chemist. For the most part, the interesting information that…

Britain’s Big Space Balloon is a huge high altitude research balloon, intended to explore the highest areas of the atmosphere. The super pressured balloon will fly up to 130,000 feet, above the Earth, in the stratosphere carrying climate change and…

A hot-air balloon flies or rises when the air inside the envelope is heated causing it to be less dense than the surrounding air mass. Since the less dense air is contained within the envelope, the envelope and attached basket…

For any wave, the speed or velocity (v) at which the wave travels is the product of the wavelength (λ) and frequency (f) of the wave.  This is true for light waves, sound waves, seismic waves, or even waves made…

Light and other forms of energy, including sound, are measured by its wavelength and frequency.  Wavelength multiplied by frequency is equal to the speed of light. The relationship between wavelength and frequency is that they are inversely proportional to one…

I’m sorry, but why and how is this a debate question. Asking if molecules can be changed into atoms is as silly as asking is a car can be changed into autoparts. Molecules are groups of atoms! In fact, a…

TIME IS RELATIVE…relatively speaking.One dictionary defines time as “the distance between two events.” I like this definition. It’s short and sweet, making it difficult to refute. The distance between today and tomorrow is twenty-four hours. Seven days is the distance…

Time is the most inquisitive thing to be analyzed. Time and space are interrelated. They can not be studied alone. Wherever there is space or a place, there is a time. The fact can be visualized like this: A place…

The Standard Model is hands down the most precisely and thoroughly tested physical theory of all time [See the introduction to Dr. Steven Weinberg’s three volume “The Quantum Theory of Fields”]. The mathematical structure of the Standard Model is based…
