    Excellent lecture except for the use of the word 'cool' twice. Very very unscientific vernacular. Used 'neat' once which is fine. Drop the use of the word 'cool' from your lectures please. 95 % of the people whom I have heard use the word cool have been dumb dumb's. You, of course, being in the 5% who are not. Could you imagine a heart surgeon saying 'cool' several times while performing open heart surgery on a loved one.
    Use of that word is for dope smoking kids….'coooooool man……coooool'. Thanks. Again, great lecture.

    Wake Up & Smell The Amino Acids

    One way to classify “special” smells is to smell the twenty

    basic twenty amino acids, remember them, and classify any

    “special” smell under the category of one of the twenty amino acids.

    I did that over forty years ago, and I have tables of correspondence

    tables that have the twenty basic amino acids corresponding

    to analogous things:

    > 1. itza, don, decider, alanine, dice: 4&2

    > 2. imix, drun, distributor, glycine, 6&1
    > 3. ik, ceph, memory, aspartic acid, 3&3
    > 4. akbal, graph, encoder, tryptophan, 3&5
    > 5. kun, un, extruder, hydroxyproline, 1&1
    > 6. chachuen, fam, EPR, methionine, 6&5
    > 7. cimi, orth, supporter, tyrosine, 6&2
    > 8.*oc, tal, producer, threonine, 4&4
    > 9. lamat, vau, internal trn., valine, 5&5
    > 10. muluc, gon, output trn., glutamine, 4&5
    > 11.*manic, pe, ingestor, lycine, 4&6
    > 12. chuen, ged, storage, phenylalanine, 2&5
    > 13. eb, med, channel&net, asparagine, 3&6
    > 14. ben, gizga, EPA, cysteine, 1&3
    > 15. ix, ur, reproducer, proline, 2&3
    > 16. menn, mals, decoder, serine, 6&6
    > 17. kib, veh, motor, histidine, 1&2
    > 18. caban, pal, boundary, glutamic acid,1&5
    > 19. eznab, nahath, input trn., leucine, 2&2
    > 20. cuac, ger, associator, isoleucine, 4&1
    > 21. ahau, gal, converter, arginine, 4&3
    > *: These have been exchanged in modern times. EPR is
    > Entropy Prodction Rate. EPA is Entropy Production
    > Acceleration. And, trn. is transducer.

    These words have meanings in different languages. For example, let’s take the last one here,

    #21, ahau means flower, and is one of the twenty Mayan calendrical symbols.
    It was amazing; Dr. John Dee, in the Sixteenth Century, presented the Enochian alphabet,

    whose names don’t sound like the letters they represent, but, the names of these twenty-one

    letters mean the same as Dr. James Miller’s subsystems in his book

    “Living Systems”, the primary text book of living systems dynmaics.
    For example in #21 the word “gal” is the pre-Aryan word for the living systems subsystem the

    “converter”. One of the twenty amino acids produced from the DNA code, in this case “arginine”,

    is represented here. The extra amino acid in this system is hydroxyproline,

    which is produced from a code in the “junk” DNA, the most

    important product of the “junk” DNA.
    The DNA code is composed of combinations of four nucleic acids, giving 64 different

    combinations, like the Yi Jing. But, most of the basic 20 amino acids are produced from more

    than one of these combinations. These 20 amino acids compose proteins which build the body and

    assemble other compounds together to compose our complete body.
    There are seven levels of living systems: cells, organs, entities (like us, animals, and plants),

    groups (like families, gangs, teams, etc.), organizations, societies, and suprasocietal living

    systems. All of these depend upon their 21 subsystems. If any subsystem is missing, a higher living

    system must provide a substitute, or, that living system with the missing subsystem will die.
    The number combinations at the end of each line of correspondences represent the combinations

    of dice symbols, which have symbols to represent them: 1, . ; 2, U ; 3, / ; 4, O ; 5, X ; and 6, = .

    You will notice that these symbols span the usual dice symbols.
    Now we combine these six into 21 symbols. The way I’ve seen the 4&3 drawn is a circle with a

    vertical diameter, which also represents the lette D. So, each one of these also represents a

    letter. Also, of coincidence for English speaking people, the compination for B is 4&6, which

    is a cicle with a horizontal parallel in it that makes this symbol look like a bumble bee (B).
    Since we use these subsystems all the time it is organizing to notice them. For example, when

    we go grocery shopping for our family, we become the ingestor by getting the groceries, extruder

    by extruding the money to pay for the groceries, distributor by bringing the groceries to our

    family, and then we use the storage subsystem of our family (group) by storing the groceries

    where they are stored. And, if we decided what to buy, we were

    also the decider for our family.
    But, every group, organization, society, and suprasocietal living system, has a decider that has

    been called a group mind. The Greek for “group spirit” is “demon”, which comes from the Greek

    root “dem” from which we get the word “democracy”. So, we have the group mind to

    help us. Then, that’s literally “demonic”.
    The group entity is a magnetic flux circulating through all the medullas in the brains of all

    the group’s members. But, us Christians are only supposed to have Jesus Christ as our group mind,

    “having the mind of Christ”, and, being members of the “Body of Christ”.
    In the Middle Ages the ranks of these fallen “angels” were defined. The demon of a group was

    called an angel; for an organization, an archangel; for a society, a principality;

    and for a suprasocietal living system, a power.
    Now you can see what was meant, “We fight not flesh and blood; we fight principalities and powers”.

    Smelling licorice is like, but easier than, transcendental meditation. Licorice is synesthetically

    onomatopoeic to a hollow cylinder, and it stirs closed circuitry in the brain that

    goes confluent with the circuit that is the entity so that near nonexistence, nirvana,

    is experienced. Everything is actually striving for nonexistence.

    Nonexistence is the ultimate essence of pleasure. The corresponding sound, the sound of a hollow

    cylinder, pronounced “eyennn”, like the German word for one, “ein”, means “nothingness”,

    “aleph yod nun”, in Hebrew, and is onomatopoeic by meaning a well, but, it also means an eye and a ring.

    The movie “The Ring” plays upon this, the “lost word”.

    Protein is very essential for the growth of the body, to repair damaged tissue, maintaining body functions and also mainly for the immunity system to protect you. Proteins are antibodies that kill bacteria, viruses, and fungi that enter the body. They need to produce hormones that need to the function of the body. Almost all the enzymes used to digest foods are produced from them. They also help to transport various substances and compounds through the blood. As an example, Hemoglobin is a protein that transports oxygen from the lungs to other cells. Therefore it is very important to take a necessary amount of protein from foods daily.

  • Reply rgudduu March 5, 2020 at 7:03 am

    When protein folds, do the backbone bonds remain intact? Since so many atoms are then close together, we don't know which atoms hv bonds between them, no? Those bonds before folding, that we draw in the picture, aren't 'hard-wired' in real, isn't it?
