Abstract: Contemporary physics has many unsolved problems. Most of them are due to inadequacy of theories or illogical application of one theory to seemingly similar problem elsewhere. An alternative concept, presented in book ‘MATTER (Re-examined)’ proposes to provide logical explanations to all these apparent problems. In this article, author proposes to present short notes and pointers to detailed explanations in the book. All explanations are based on a single assumption that ‘Substance is fundamental and matter alone provides substance to all real entities’. There are neither imaginary particles nor mysterious actions nor actions at a distance through empty space in this concept. Cause and effect relations are followed in all topics.
