Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibres derived from wood, rags, grasses or other vegetable sources in water, draining the water through fine mesh leaving the fibre evenly distributed on the surface, followed by pressing and drying. Although paper was originally made in single sheets by hand, almost all is now made on large machines—some making reels 10 metres wide, running at 2,000 metres per minute and up to 600,000 tonnes a year. It is a versatile material with many uses, including printing, packaging, decorating, writing, cleaning, filter paper, wallpaper, book endpaper, conservation paper, laminated worktops, toilet tissue, currency and security paper and a number of industrial and construction processes.
The papermaking process developed in east Asia, probably China, at least as early as 105 CE, by the Han court eunuch Cai Lun, although the earliest archaeological fragments of paper derive from the 2nd century BCE in China. The modern pulp and paper industry is global, with China leading its production and the United States following.
i am last year electrical engineering student.
my project is really technically innovative & theoretically sound with mathematical background.
so i want to publish my project on 'theoretical level'.
what is the procedure for it?
I have a multiple choice question paper from ISRO 2012.

Hiya,
First off, I'm not sure where to post this topic. I was thinking either the homework section, or General Astronomy, but I chose to put it here because my question relates to a research paper in Astronomy.
Let me discuss the basics of the paper. We have to pick a topic in the 1920s that...
In a theoretical paper, the primary investigator which is my advisor, is first author, and he also writes the first draft. Me, the second author, and another graduate student have contributed substantially to the numerical simulation. We have another external collaborator which has not...

Hello, can somebody give me the link to Paul Dirac's research paper(1933) which showed that if any magnetic charge exists, then electric charge is quantized?

It is commonly said (based on a quick Google search) that wrapping your beer in a wet paper towel and placing it in the freezer will allow it to cool faster than placing it in the freezer without said paper towel.
Newton's Law of Cooling suggests otherwise. The fact that water releases energy...
"Quantum jump" is a somewhat misleading term because the transition is not instantaneous. We can assume that at any given temperature there is a characteristic length of time it takes for the system to make the transition to a distinct quantum state. A local observer's proper time is essentially...
Hi, I'm 14 and i like physics too much to just stick with the Newton laws at school, I learned Calculus and Special Relativity, and now I'm learning Mathematical Background for Quantum, I was wondering... After I learn Quantum can I send a research to college (my dad gave me this idea)? And if I...
In his 1905 paper introducing special relativity, Einstein calls attention to the asymmetry in the classical treatment of the relative motion of a magnet and a conductor:
In a previous post, it was explained to me that, when the conductor is moving, the electromotive force has "in itself ...

Hi there,
I'm doing a paper about the special theory of relativity. The paper consists of two parts:

Hi,
Does anyone have any experience with this synthetic paper made by Decro?
It is very similar to the material that those "Fatheads" are made out of. This paper comes in 44" x 100' rolls and is used to make banners, signs, etc.
It has a base material of polypropylene. Just wondering if...
In another thread, Dalespam posted this paper:

The paper is, overall, very nice and introduces a very convenient unification of all coordinate systems for the spherically symmetric vacuum GR solution that manifest the static character ( of the exterior...

http://www.vibsys.put.poznan.pl/journal/2010-24/noga-2.pdf
Equations (9) leads to (11).
How from R boundary condition do we end up with the equation in (11)?
In the paper, http://arxiv.org/pdf/1205.3365v1.pdf, page 21, the author argues that if:
t →∞(1-iϵ), all the terms in equation (193) goes to zero, except the first term.
Can anyone explain this to me?
Thanks
