Dear readers, I appreciate your time and patience to read/try to read my article. However, this is not a simple article: as it describes the universe in informational terms (as it is a model of the universe; Bio-Info-Digital-Universe-Model [BIDUM]) and has almost 60 pages, it tends to be more like a manual in which I have reformulated a lot of classical and modern concepts of physics. Like any manual/book-like article, the abbreviations are inevitable, as I also try to impose new general concepts (together with their abbreviations which I try to propose too). If I had used the classical terms with a minimal abbreviational strategy, the phrases would become very complex and hard to read as the explanations have a lot of parenthesis (as I practice a tree-like multi-level phrase structures). The main abbreviations I have imposed is for fundamental physical concepts I try to present and I always first explain them (and mention them between parenthesis). These are the most frequent: (elementary) quantum particle ([E]QP), gauge-boson (GB), non-gauge particle (NGP), physical information (quantity/quanta) (PI[q/qua]), biological information (quantity/quanta) (BI[q/qua]), biophysical information (quantity/quanta) (BPI[q/qua]), physical observer (PO), biological observer (BO), Fine Structure Constant (FSC), GCC (gravitational coupling constant), fundamental forces/fields (FFs): strong nuclear force/field (SNF), weak nuclear force/field (WNF), electromagnetic force/field (EMF), (electro)gravitational force/field (EGF), super string theory (SST), M-theory (MT) etc. The majority of the rest of them are standard abbreviations used in standard physical language. I have also anticipated the difficulty of reading this manual-like article, that is why I have also created this separate file with all the abbreviations used in my BIDUM. Important remark: this update is also due Sergey G. Fedosin which I want to thank again as he convinced my once again that this table of abbreviations is a must to share with all my readers.
