What I liked (I am being a bit "transparent" here) was his sometimes poetic ways of describing the sun. I want to quote from various of my small collection of (mostly tatty, and new and old Pelicans). The other books I used to read when I was a teenager included many of those in The Scientific Book Club, which covered a wide range of subjects (Gorrillas, mating rituals, astronomy, one on drugs (the only one ever to be stolen, it included stuff on LSD and psilosibin etc), Asimov's history of Biology.
In my late 20s to mid to late 30s I studied telecommunications and electronics at MIT and AIT (used to be MTI and ATI when I was there). I also did a course in Accountancy and business etc as I have in fact been involved in some small business ventures (ca 1988 and at various other times). Later I did some (fairly basic) study of Computing although I had fairly good knowledge of digital electronic systems in the 80s.
More recently I have read books variously on neurology, cell biology, experiments at the molecular of substance level, a theory of the cell as kind of computer (Dennis Bray in Wetware), and more or less popular books on mathematics as well as books by Richard Dawkins and J. D. Barrow's various books on maths, cosmology etc e.g. The Science of Limits and the Limits of Science.
I think a writer or artist who shuts his or her mind to any area of study etc is limiting her or himself. That said I have my own prejudices, old ideas, misconceptions, fixed ideas, and likes and dislikes...
So we strike a balance. I studied philosophy in the 90s and one area that interested me was epistemology and the problem of knowledge.
Initially I was using these (somewhat) for the specific "language" exhibited in each (and the more or less mysterious signs and symbols used in those areas) but I was also interested.
So, this is thus the KNOWLEDGE component of EYELIGHT (although of course dividing things up in this way is quite arbitrary and necessarily limited but then everything is limited...
I also have to concede that their are areas that are, as far as I can see, are almost beyond my understanding. I think I was fascinated in the idea of this reality and was always very far from understanding it all. The "use" of it all to me is the way I can cut it all up and "feed" it into other aspects of what I am doing - of course if someone wishes to discover these things more they can do what I did for blood and take if from Wikipaedia (I have given money to them). But I think (possibly) my reasons for cutting and pasting in many (not all, as what I also love, are the words, the phrases, and thus the act of copying these mysterious and often almost incomprehensible, and almost Infinite potentials of knowledge at least in some small "packets" is something I do in every book I read. (I once copied an entire book, word for word, by hand [this was in the early 70s and it didn't occur to me that there were such things as copying machines!) but I have since had a desire to do as Goldsmith
In vertebrates, it is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains dissipated proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells (also called RBCs or erythrocytes) and white blood cells, including leukocytes and platelets. The most abundant cells in vertebrate blood are red blood cells. These contain hemoglobin, an iron-containing protein, which facilitates transportation of oxygen by reversibly binding to this respiratory gas and greatly increasing its solubility in blood. In contrast, carbon dioxide is almost entirely transported extracellularly dissolved in plasma as bicarbonate ion.
Vertebrate blood is bright red when its hemoglobin is oxygenated. Some animals, such as crustaceans and mollusks, use hemocyanin to carry oxygen, instead of hemoglobin. Insects and some mollusks use a fluid called nemolymph instead of blood, the difference being that hemolymph is not contained in a closed circulatory system. In most insects, this "blood" does not contain oxygen-carrying molecules such as hemoglobin because their bodies are small enough for their tracheal to suffice for supplying oxygen.
Jawed vertebrates have anadaptice immune system, based largely on white blood cells. White blood cells help to resist infections and parasites. Platelets are important in the clotting of blood.
Blood is circulated around the body through blood vessels by the pumping action of the heart. In animals with lungs, arterial blood carries oxygen from inhaled air to the tissues of the body, and venous blood carries carbon dioxide, a waste product of metabloism metabolism produced by cells from the tissues to the lungs to be exhaled.
Medical terms related to blood often begin with hemo- or hemato- (also spelled haemo- and haemato-) from the Greek word αἷμα (haima) for "blood". In terms of anatomy and histology blood is considered a specialized form of connective tissue, given its origin in the bones and the presence of potential molecular fibers in the form of fibrinogen..
The albumins (formed from Latin: albumen "(egg) white; dried egg white") are a family of globular proteins the most common of which is serum albumin. The albumin family consists of all proteins that are water-soluble, are moderately soluble in concentrated salt solutions, and experience heat denaturation. Albumins are commonly found in blood plasma, and are unique from other blood proteins in that they are not glycosylated. Substances containing albumins, such as egg white, are called albuminoids.
A number of blood transport proteins are evolutionarily related, including serum albumin, alpha-fetoprotein, vitamin D-binding protein and afamin.
green = haem groups
red & blue = protein subunits
- Supply of oxygen to tissues (bound to hemoglobin, which is carried in red cells)
- Supply of nutrients such as glucose, amino acids, and fatty acids (dissolved in the blood or bound to plasma proteins (e.g., blood lipids))
- Removal of waste such as carbon dioxide, urea, and lactic acid
- Immunological functions, including circulation of white blood cells, and detection of foreign material by antibodies
- Coagulation, which is one part of the body's self-repair mechanism (blood clotting after an open wound in order to stop bleeding)
- Messenger functions, including the transport of hormones and the signaling of tissue damage
- Regulation of body pH
- Regulation of core body temperature
- Hydraulic functions
Constituents of human blood
Two tubes of EDTA-anticoagulated blood.
Right tube: contains freshly drawn blood.
Blood accounts for 7% of the human body weight, with an average density of approximately 1060 kg/m3, very close to pure water's density of 1000 kg/m3. The average adult has a blood volume of roughly 5 liters (1.3 gal), which is composed of plasma and several kinds of cells. These blood cells (which are also called corpuscles or "formed elements") consist of erythrocytes (red blood cells, RBCs), leukocytes (white blood cells), and thrombocytes (platelets). By volume, the red blood cells constitute about 45% of whole blood, the plasma about 54.3%, and white cells about 0.7%.
Whole blood (plasma and cells) exhibits non-Newtonian fluid dynamics; its flow properties are adapted to flow effectively through tiny capillary blood vessels with less resistance than plasma by itself. In addition, if all human hemoglobin were free in the plasma rather than being contained in RBCs, the circulatory fluid would be too viscous for the cardiovascular system to function effectively.
- 4.7 to 6.1 million (male), 4.2 to 5.4 million (female) erythrocytes: Red blood cells contain the blood's hemoglobin and distribute oxygen. Mature red blood cells lack a nucleus and organelles in mammals. The red blood cells (together with endothelial vessel cells and other cells) are also marked by glycoproteins that define the different blood types. The proportion of blood occupied by red blood cells is referred to as the hematocrit, and is normally about 45%. The combined surface area of all red blood cells of the human body would be roughly 2,000 times as great as the body's exterior surface.
- 4,000–11,000 leukocytes: White blood cells are part of the body's immune system; they destroy and remove old or aberrant cells and cellular debris, as well as attack infectious agents (pathogens) and foreign substances. The cancer of leukocytes is called leukemia.
- 200,000–500,000 thrombocytes: Also called platelets, thrombocytes are responsible for blood clotting (coagulation). They change fibrinogen into fibrin. This fibrin creates a mesh onto which red blood cells collect and clot, which then stops more blood from leaving the body and also helps to prevent bacteria from entering the body.
