The Black-and-White Fantail

the black hole and the white dwarf

astrophysics is becoming now an integral part of general physics. considering the black hole theory ,which is a new and exciting branch of relativistic astrophysics, we see many connections between elementary particle physics and astrophysics. in this article we attempt to explain the development of star physics ,in an easy ,understandable manner. previous knowledge of relativistic theory or cl...

These ruminations are based on based on UTR 25 (Unicode and Mathematics), revision 7, section 2.11 (Geometric Shapes) in particular. The conclusions are-(i) a plea for more consistency when naming characters; (ii) a request that characters based on abstract shapes should have some indicator of the size of the character relative to the rest of the font; (iii) that the code chart entry for U+2023...

Black and White and Colour

Capturing the Color of Black and White

One of the first and iconic imaging targets to be developed for color photography was described by McCamy, Marcus, and Davidson. That was more than thirty years ago and, for better or for worse, the Macbeth ColorCheckerTM continues to be a de-facto target standard in imaging circles. The target was designed to simulate the spectral nature of critical or problematic colors for consumer photograp...

The dangers of black-and-white conservation.

The world is a complex place. To simplify this complexity, people often reduce it to simple either–or choices— black or white, do or don’t, yes or no, winners or losers, nature or nurture, and so on. Even our computer systems are based on binary logic. Conservationists are people, so we tend to do this too. Case in point: protected areas. Protected areas have long been the cornerstone of conser...
