by absorption of laser I mean reduction of its power (this is not the same as shooting a bullet). as you know, atmospheric use of laser is heavily influenced by turbulence (The basic mechanisms of atmospheric currents are wind shear and heating. Under turbulent conditions, flow is broken up into...

I have 2 questions: 1- how tough is building an electronic distance measurement device (a rather small one such as the one's used in land surveying total stations) which for instance can indicate distance of a particular point 1 km away? (our device should fire a laser beam towards the point...

I don't know anything about physics but some times I wonder whether a particular procedure is possible or not. As for this post, It is known that a major problem with use of laser is absorption by the environment (ex. clouds or any form of water vapor). It is also known that laser (as far as I...

This will produce a sense of detachment.

think of fastening the cup (or other relevant objects in the campartment) with magnetic (invisible) force. The force must be activated only when the sensors predict a near braking incident. At usual times external regulated force should suffice.

you talked about inertia. "Yes, the coffee must be there". however, when the whole compartment is not moving at all do you think inertia would be a problem. inertia is true if you are attached to compartment by any means. imagine a car is moving and and at the same time an appel is floating on...

Bose has developed an active electromagnetic suspension that accomplishes exactly what you are looking for. Here's a link to a video comparing the Bose suspension to your standard, everyday hydraulic suspension. http://youtube.com/watch?v=eSi6J-QK1lw I watched the clip (I appreciate it)...

To be more precise, I am thinking of using magnets (opposing forces of magnets to be used for compartment suspension). This should be irrespective of the wheels and physical structure of the passenger car.

I have been thinking whether it is possible to make a car with non-shaking compartment. Meaning that when the car moves, its internal compartment will not shake at all such that a passenger may just place a cup of coffee on the table while the car is moving on a rough surface.

Hello, I have seen some very good analysis on this website. Therefore, I would like to get some comments on my idea. I was thinking how practical is to develop a sheild by rapid and powerful shooting of numerous Iron blades (with diameter and length slightly bigger than a bullet) over a...

upon reading the first part of your reply I can conclude, - If your phpadmin does not have any problem then you should not need any decode() or encode() mechanisms (thus, your brief code also shows that you are not using any). Upon reaing the second part of your reply I can tell you...

I think there are a number of possibilities you can go for, which are: 1- check to see the integrated environment you use for php + mysql is supporting chinese or not (for instance xampp software supports a number of languages and can make your life easy. I have tried mysql for persian...
