They make a path for radio waves to follow in our atmosphere. 它可以使无线电波按照一定途径进入我们的大气。 These natural waveguides occur when the Sun is rising or setting, which makes sunrise and sunset good times to pick up VLF emissions. 当日出或日落的时候,这些波导就会产生,这样日出日落时...
What occurs when the frequency of a forced vibration is the same as the object's natural frequency? If the fundamental frequency of a note is 200 Hz, what is the frequency of the second harmonic? What does beat frequency presents in physics? At what frequency must the string vibrate to fo...
This looks like a rather strange system; but it is three vector equations (3), (4), (5) in four vector (or one-form) unknowns , together with a divergence-free condition (6) and a positive definiteness condition (7), which I view as basically being scalar conditions. Thus, this ...
This is a review of the issue of randomness in quantum mechanics, with special emphasis on its ambiguity; for example, randomness has different antipodal r
the planet is unbelievably massive and has more than met the demands of a few Billion people in fact, with ever less poverty and deaths from disease and famine than ever. The whole concept of sustainability is meaningless or falsely asserted in many of the contexts it is used – to control...
Optical physics is the study of light and its interaction with matter. Most of us think of light as an illuminating energy. With light, we can see things. Without it, we’re in the dark. To optical physicists, though, light is a series of electromagnetic waves that vary widely in their...
the impact of computer simulation (Hashagen ). One of the stan- dard historical references in this context is Galison's work on Monte Carlo methods and how they required as a simulation method, the constitution of a "trading zone" where different practices (including ...
In physics,frequencyis a property of a wave, which consists of a series of peaks and valleys. A wave’s frequency refers to the number of times a point on a wave passes a fixed reference point per second. Other terms are associated with waves, including amplitude. A wave’s amplitude re...
Late last week, workers on an oil rig(钻井平台) noticed the animal, all alone, in the water. It began swimming toward the side of the rig. The dog was able to get itself onto a solid area. He appeared cold, tired and fearful. The workers lowered a rope and secured it around the ...
