Uses the Doppler effect to detect frequency shifts in the transmitted pulse caused by the radial velocity of detected targets.  The echos is processed through a series of RF filters &, based on the amount of frequency shift & angle of approach, the radar can then determine the true target velocity.\n\nMostly used in weather apps.\n\nPS. the speed of light is normally rounded to 3*10^8 meters/sec or 300,000,000 m/s.  Also Doppler is a guy's name.  (Christian Johann Doppler 1803-1853 Austrian physicist)

Well, you didn't say whether you're building a building, a bridge, a trestle, a tower, or other structure.  But you could start with some general articles, like this Wikipedia article, which has links to specific sites which give some specifications.\n\nThe other link gets properties for different I-beam sizes--I presume you understand the terminology well enough to read the resulting tables.

Shorty does have it right but the propulsive thrust, I hypothesize, is from the elastic contraction of the balloon as air exits the hole (nozzle). Air placed into a balloon is under pressure from the expanded rubber walls. When the nozzle in a filled balloon is opened, the air rushes to equalize with the outside (where the pressure is lower) as the balloon collapses to its rest state. This jet of air propels the balloon in the opposite direction of the thrust but it is not perfectly aligned with the travel-axis of the balloon and tends to drive it in a spiral path as the stem of the nozzle rolls around the axis of flight. The nozzle is also interrupted by the cyclical sputtering of the balloon’s elastic nozzle. Both of these effects can be modeled by differential equations. The on-off nature of the air through the nozzle as well as the off-center nozzle alignment at the end of a stem accounts for the balloon's spiraling, erratic flight.

A BEAM of particles behaves like a wave\nas you know. The wavelength is h/mv.  (De Broglie)\nInteresting is your question: do moving partikels create a wave? I cannot say yes or no. I will think about it very carefully. fd_r@yahoo.com\n\nAdded later. You suggest space/time is waving.\nTo me space and time are nothing physically. It is only fantasy in man’s brain and it works usefully.\nEinstein is talking about curved space. I cannot imagine that. I can only understand curved matter like a rubber ball and a standing wave in a string of a guitar. I cannot grab space and bend it.\nIn the same way I cannot visualise the concept of an oscillation of space, so an oscillation of nothing.\nMore acceptable for me is an electromagnetic wave as a cluster of oscillations of the electric and magnetic field.\nI do not reject your concept of waving space/time. I only cannot imagine. Maybe I am too simply minded. Maybe with waving space/time there is a field, not electromagnetic, because a beam of neutrons shows wave behaviour as well. What kind of field? Gravitational? I do not know.

assuming the object is not self powered or already in motion from somebody's pushing or wind power - then it is an optical illussion

Generally, I'd say transfering energy using a microwave beam would be hazardous to anything living in the beam, however, it depends on the intensity, or beam density. If you're transfering enough energy to be usefull, I'd say it was dangerous, unless the beam was very wide, and your collectors were very large, then the beam density would be low, but such an unfocussed beam would be inefficient. \nMicrowave radiation is all around us, naturally and artificially generated - background radiation, line of site communications, radar guns, etc.....

to accelerate particles :p\n\nActually, I know one purpose quite well, next year I'm going to be doing research with a particle physicist(im a physics major) and I know that what he's using it for is to accelerate particles so they're moving really really fast and then crashing them into each other and seeing what kind of junk comes flying out.  This is how they discover new particles.  They are currently working on a particle that is undetectable, but they know it's there because there's another particle shooting out in a different direction, and in order for the forces to be balanced the way that they are, there must be something there...\n\nCrashing particles together at these ginormous accelerations is really interesting actually, because when you crash them together so that they combine, you sometimes get a particle that has more mass than the sum of the 2 masses you started with!! So where is that extra mass coming from? Some of the energy is actually being converted into mass through Einstein's famous formula E=mc^2.

I admire mathematician's concise answers, but in this case some additional explanation may be due:\n\nWhen a wave is partially transmitted and partially reflected the two outgoing waves are shifted in phase from the incident wave. If energy or probability is to be conserved, the difference between the two phase shifts is pi/2 (90°). In this diagram each of the two possible outgoing  beams consist of components from two paths (R=Reflection,T=Transmission):\n\nOutgoing Horizontal: TRR + RRT\nOutgoing Vertical: TRT + RRR\n\nIn the first case the relative phase shift between the two components is 0 and in the second case it's pi (180°) ==> the two components are negatives of each other and interfere destructively.

An impulse turbine is one where water flows out of a nozzle and hits the turbine blade to give up its kinetic energy.  A "Pelton wheel" is an example of an impulse turbine.\n\nA reaction turbine reacts to the flow of the water past its blades.  It doesn't have a jet nozzle, the turbine is just set in the water flow.  A "Kaplan turbine" is an example of a reaction turbine.

Lasers are generally classified by the state of the substance excitied to make light: solid, liquid, or gas.  The fist lasers were solid (ruby), but gas lasers have become more common.\n\nLasers are also classified into pulse or continuous beam lasers.  Pulse lasers build up energy and release it periodically, usually several times a second - these have interesting industrial applications.  The lasers used in CD and DVD players and light shows are continuous beam lasers.

The Beamsplitter (basically) splits the infrared light into two halves. One half of the split light beam travels to a moving mirror in the interferometer and the other half to the fixed mirror. Both beams are reflected back to the beamsplitter where they recombine. Half of this recombined energy (the interferogram) is transmitted to the detector. All of this occurs in on every stroke of the moving mirror. This data (collected in the time domain) is then transformed via the Fourier algorithms to the frequency domain. A series of these scans with nothing in the sample compartment constitutes the “background”, then the sample is added, scans collected again, and the sample collection is ratioed against the background collection and what is left are the infrared absorptions of the sample.

On the contrary, a light beam would merely percieve that it travelled instantly inbetween origin and destination. Space would be warped to Zero distance in the direction of travel, not Zero space. I know it seems like a sleight-of-hand trick with the mathematics, but the distinction is important.

Mostly used to seed clouds jets can fire them into clouds or a flare can be used.  This is still used but can be very expensive.  Recently they stopped a drought in Austrilia by seeding some clouds.  Also i believe its spelled Silver iodide :-p im sure it was just a typo. AgI everyone does it

There is often a wide divergence between theory and application.  I remember one application where lengthy mechanical linkages and cables were used to transmit rudder position for a huge seagoing ship in the even that the steering gear room became flooded (and electronic indication was lost).  The system had too much lost motion to indicate rudder position even though it looked good in theory.  I suggested connecting a vertical rod to the rudders that pierced the overhead into the ("unflooded") compartment above which could be connected to a reliable electronic transmitter (similar to existing "flooded" transmitters) and that worked much better.  Even electronic control systems can exhibit unexpected hysteresis when built.

They talk about it in the link below. I think it's basically the effect of the string bed on the racket kind of being pushed back as the shuttlecock hits it, and then bouncing back, sending the shuttlecock on its trajectory, much like a slingshot works: the sling material is pulled back, and then when you let go, it flings the object forward at great speed.\n\nSo, no, it's not a fault, it's just the effect that occurs when the shuttlecock hits the racket.
