Photobioreactor-Based Energy Sources,imilar triangles, it may be necessary to also include uniform scalings.) Projective geometry, on the other hand, can be considered to be the study of properties left invariant under projective transformations. In this sense, topology is just the study of properties left invariant under homeomorphisms, i.e., bicontinuous mappings.

Introduction to General Relativityine relative to each other, describe nature in identical terms. Certainly, aesthetics demands that if nature would not show preference for one or the other of two observers in uniform rectilinear motion relative to each other, then it should also not show any preference between two observers with an

Introduction to Black Holesmatical existence of the black hole, as embodied in the exact solution of Schwarzschild, dates back almost to the advent of general relativity itself, most of the relevant aspects related to it were discovered essentially after the mid-sixties. These include the geometric structure of the black hole

Introduction to Relativistic Cosmologysable. Starting from simple observational facts combined with a limited number of conceptual assumptions, one can build elegant cosmological models based on general relativity. These models have been quite successful in providing a framework for considering various physical processes in detail and i

An Approach to Anisotropic Cosmologiesof physics. Normally, one has some observational data and the theoretician goes on to build up a structure with a minimum of . assumptions which help to systematize and ‘explain’ the data. In 1917, Einstein had hardly any observational data to explain and the little he had, he chose to ignore. Even
