Foreword / How to read this doc
This document was written for developers who have worked with Java™ before and want to start developing for the Android Platform. I tried to make this as much “hands on” as possible, placing example codes everywhere it fit. Also I tried to insert as many picture as possible, because they liven up the learning process and relax the reader’s eyes

This book deals with topics in atomic and molecular structure and
dynamics that are important to astronomy. Indeed, the topics selected
are of central interest to the field of astronomy, many having been initiated
by the needs of understanding worlds other than ours. Except
for some lunar surface material returned by the Apollo missions, and
material naturally delivered to us by cosmic rays, comets, and meteors,
our only access to the other worlds of our astronomical Universe is
through our observations of electromagnetic radiation from them.

As your choice of today will directly influence your picture of tomorrow, it is important to correctly
choose your projector depending on the field of application you would like to use it in. A digital
cinema projector remains after all a cinema projector! To choose the projector model it is essential
that it is correctly adapted to the size of the screen that it has to illuminate ...
Home theater projection has always promised greater viewer
engagement, the prospect of a bigger, more exciting, more
enveloping picture than just television. Greater engagement
requires the screen to fill a larger field of view. This can only be
achieved by sitting closer to the screen or increasing the overall
screen size. But this has always run the risk of exposing image
artifacts that pass without notice on smaller screens.
The film print shown in theaters is typically a copy of a copy of a copy,
three generations removed from the Original Camera Negative. Each generation
sacrifices detail and contrast, leaving audiences with a pale imitation of the
original. Digital presentation is typically far closer to the Original Camera
Negative, enabling much higher picture quality.
Stability. Film projectors must “pull down” each frame, then pause while that frame
is projected. This process is inherently mechanical and somewhat imprecise.
A more engaging movie experience depends on sitting closer to the screen.
But how close is close? The answer varies by screen size. The same viewing
distance that is “close” for a 70-foot screen is “far” for a 20-foot screen.
To account for screens of different sizes, we need a special way to measure
viewing distance. That’s why engineers consider viewing distance as a
multiple of Picture Height (PH).
Based on widely-accepted measures for the threshold of visual acuity,
2K presentation will satisfy audience members with 20/20 vision who sit at
distances of 3.
In pursuit of a more engaging experience, one might be tempted to sit closer
to a 2K presentation. But moving closer than 3.16 PH causes unwanted
on-screen artifacts to become more obvious. The illusion of a continuous
image begins to break down as individual pixels become evident. Subjects
that present fine detail such as motion picture credits will appear especially
rough. Image diagonals will appear jagged. And gaps between the pixels
may also become visible. This is called “screen door effect” because viewing
the movie becomes like looking through a screen door. ...
At the start
of the 1960s, the studios were providing lucrative prime-time television pro-
gramming, but theatrical moviemaking was not a great business to be in.
Attendance was falling sharply. Road show pictures like The Sound of Mu-
sic (1965), playing a single screen for months on end,were for a while bright
spots on the ledger, but the cycle of epic road show productions, already over-
stretched with the failure of Cleopatra (1963) and Mutiny on the Bounty
(1965), crashed at the end of the decade.
To placate the resurgent opposition, the MPPDA promised to abide by a set of guidelines
more extensive and restrictive than the simple nostrums enshrined in the “Don’ts and Be
Carefuls.” The document that articulated the new commitment to screen morality was the
Production Code. Written in 1929 by Martin J. Quigley, an influential editor and
publisher of motion picture trade periodicals, and Reverend Daniel A. Lord, a
multitalented Jesuit who first lent his spiritual expertise to Hollywood as the Catholic
advisor to Cecil B.
