The evolution of our Universe and the formation of stars and galaxies are mysteries that experience lengthy wondered scientists. contemporary years have introduced new clinical figuring out of those profound and primary concerns. In energetic prose, Professor Padmanabhan paints an image of latest cosmology for the final reader. in contrast to different well known books on cosmology, After the 1st 3 mins doesn't gloss over information, or draw back from explaining the underlying options. as a substitute, with a lucid and casual sort, the writer introduces the entire appropriate historical past after which rigorously items jointly an interesting tale of the evolution of our Universe. Padmanabhan leaves the reader with a cutting-edge photo of scientists' present knowing in cosmology and a prepared style of the thrill of this fast-moving technological know-how. all through, no arithmetic is used and all technical jargon is obviously brought and strengthened in a convenient thesaurus on the finish of the e-book. For normal readers who are looking to come to grips with what we actually do and do not learn about our Universe, this publication offers a thrilling and uncompromising learn. Thanu Padmanabhan is a Professor at Inter-University Centre for Astronomy and Astrophysics in Pune, India. he's the recipient of diverse awards and writer of 3 books, constitution Formation within the Universe (Cambridge, 1994), Cosmology and Astrophysics via difficulties (Cambridge, 1996), and, including J.V. Narlikar, Gravity, Gauge Theories and Quantum Cosmology. he's additionally the writer of multiple hundred well known technology articles, a comic book strip serial and several other general columns on astronomy, leisure arithmetic, and the historical past of technology.

Extract Class if a class is doing too much to have a meaningful name. Extract Method if a method is doing too much to have a meaningful name. Inline Class if a class is too abstract to have a meaningful name. Single Table Inheritance (STI) Using subclasses is a common method of achieving reuse in object-oriented software. Rails provides a mechanism for storing instances of different classes in the same table, called Single Table Inheritance. Rails will take care of most of the details, writing the class’s name to the type column and instantiating the correct class when results come back from the database.

Rails will take care of most of the details, writing the class’s name to the type column and instantiating the correct class when results come back from the database. Inheritance has its own pitfalls - see Composition Over Inheritance - and STI introduces a few new gotchas that may cause you to consider an alternate solution.

Prevention By following Composition Over Inheritance, you’ll use STI as a solution less often. Comments Comments can be used appropriately to introduce classes and provide documentation, but used incorrectly, they mask readability and process problems by further obfuscating already unreadable code. Symptoms • • • • • Comments within method bodies. More than one comment per method. Comments that restate the method name in English. TODO comments. Commented out, dead code. join(', ') end This comment is trying to explain what the following line of code does, because the code itself is too hard to understand.
