Pepsi

Yeh dil mange more..

Aren't these ads of pepsi, mountain dew etc. injecting an attitude of a different kind into the new generation? A dont care or do anything kind of attitude, without thinking about the after effects? That shootout in a delhi school comes to my mind now.. Are incidents like this the resultant of such ads?

The answer to last trivia was Pepsi. Congrats Deepthi, for being the lucky winner, and congrats to all those who got their answers correct. Now, moving on to today's trivia..

This material consists of many microscopic crystals of iodoquinine sulphate (herapathite) embedded in a transparent nitrocellulose polymer film. The needle-like crystals are aligned during manufacture of the film by stretching or by applying electric or magnetic fields. With the crystals aligned, the sheet is dichroic: it tends to absorb light which is polarised parallel to the direction of the crystal alignment, but transmits light which is polarised perpendicular to it. The resultant electric field of an electromagnetic wave (such as light) determines its polarisation. If the wave interacts with a line of crystals as in a sheet of polaroid, any varying electric field in the direction parallel to the line of the crystals will cause a current to flow along this line. The electrons moving in this current will collide with other particles and re-emit the light backwards and forwards. This will cancel the incident wave causing little or no transmission through the sheet. The component of the electric field perpendicular to the line of crystals however can cause only small movements in the electrons as they can't move very much from side to side. This means there will be little change in the perpendicular component of the field leading to transmission of the part of the light wave polarized perpendicular to the crystals only, hence allowing the material to be used as a light polariser.

Sorry if it sounded like mumbo-jumbo; but the above material, known as J-sheet, was the main concept behind a product. Can you name it?
