  1. Inner Privacy of Conscious Experiences and Quantum Information.Danko D. Georgiev - 2020 - Biosystems 187:104051.
    The human mind is constituted by inner, subjective, private, first-person conscious experiences that cannot be measured with physical devices or observed from an external, objective, public, third-person perspective. The qualitative, phenomenal nature of conscious experiences also cannot be communicated to others in the form of a message composed of classical bits of information. Because in a classical world everything physical is observable and communicable, it is a daunting task to explain how an empirically unobservable, incommunicable consciousness could have any physical (...)

    Quantum Transport and Utilization of Free Energy in Protein Α-Helices.Danko D. Georgiev & James F. Glazebrook - 2020 - Advances in Quantum Chemistry 82:253-300.
    The essential biological processes that sustain life are catalyzed by protein nano-engines, which maintain living systems in far-from-equilibrium ordered states. To investigate energetic processes in proteins, we have analyzed the system of generalized Davydov equations that govern the quantum dynamics of multiple amide I exciton quanta propagating along the hydrogen-bonded peptide groups in α-helices. Computational simulations have confirmed the generation of moving Davydov solitons by applied pulses of amide I energy for protein α-helices of varying length. The stability and mobility (...)

    Launching of Davydov Solitons in Protein Α-Helix Spines.Danko D. Georgiev & James F. Glazebrook - 2020 - Physica E: Low-Dimensional Systems and Nanostructures 124:114332.
    Biological order provided by α-helical secondary protein structures is an important resource exploitable by living organisms for increasing the efficiency of energy transport. In particular, self-trapping of amide I energy quanta by the induced phonon deformation of the hydrogen-bonded lattice of peptide groups is capable of generating either pinned or moving solitary waves following the Davydov quasiparticle/soliton model. The effect of applied in-phase Gaussian pulses of amide I energy, however, was found to be strongly dependent on the site of application. (...)

  4. Quantum No-Go Theorems and Consciousness.Danko D. Georgiev - 2013 - Axiomathes 23 (4):683-695.
    Our conscious minds exist in the Universe, therefore they should be identified with physical states that are subject to physical laws. In classical theories of mind, the mental states are identified with brain states that satisfy the deterministic laws of classical mechanics. This approach, however, leads to insurmountable paradoxes such as epiphenomenal minds and illusionary free will. Alternatively, one may identify mental states with quantum states realized within the brain and try to resolve the above paradoxes using the standard Hilbert (...)

    Quantum Propensities in the Brain Cortex and Free Will.Danko D. Georgiev - 2021 - Biosystems 208:104474.
    Capacity of conscious agents to perform genuine choices among future alternatives is a prerequisite for moral responsibility. Determinism that pervades classical physics, however, forbids free will, undermines the foundations of ethics, and precludes meaningful quantification of personal biases. To resolve that impasse, we utilize the characteristic indeterminism of quantum physics and derive a quantitative measure for the amount of free will manifested by the brain cortical network. The interaction between the central nervous system and the surrounding environment is shown to (...)

    Probing Finite Coarse-Grained Virtual Feynman Histories with Sequential Weak Values.Danko D. Georgiev & Eliahu Cohen - 2018 - Physical Review A 97 (5):052102.
    Feynman's sum-over-histories formulation of quantum mechanics has been considered a useful calculational tool in which virtual Feynman histories entering into a coherent quantum superposition cannot be individually measured. Here we show that sequential weak values, inferred by consecutive weak measurements of projectors, allow direct experimental probing of individual virtual Feynman histories, thereby revealing the exact nature of quantum interference of coherently superposed histories. Because the total sum of sequential weak values of multitime projection operators for a complete set of orthogonal (...)

    Quantum Information Theoretic Approach to the Mind–Brain Problem.Danko D. Georgiev - 2020 - Progress in Biophysics and Molecular Biology 158:16-32.
    The brain is composed of electrically excitable neuronal networks regulated by the activity of voltage-gated ion channels. Further portraying the molecular composition of the brain, however, will not reveal anything remotely reminiscent of a feeling, a sensation or a conscious experience. In classical physics, addressing the mind–brain problem is a formidable task because no physical mechanism is able to explain how the brain generates the unobservable, inner psychological world of conscious experiences and how in turn those conscious experiences steer the (...)

    Computational Capacity of Pyramidal Neurons in the Cerebral Cortex.Danko D. Georgiev, Stefan K. Kolev, Eliahu Cohen & James F. Glazebrook - 2020 - Brain Research 1748:147069.
    The electric activities of cortical pyramidal neurons are supported by structurally stable, morphologically complex axo-dendritic trees. Anatomical differences between axons and dendrites in regard to their length or caliber reflect the underlying functional specializations, for input or output of neural information, respectively. For a proper assessment of the computational capacity of pyramidal neurons, we have analyzed an extensive dataset of three-dimensional digital reconstructions from the NeuroMorphoOrg database, and quantified basic dendritic or axonal morphometric measures in different regions and layers of (...)

    SNARE Proteins as Molecular Masters of Interneuronal Communication.Danko D. Georgiev & James F. Glazebrook - 2010 - Biomedical Reviews 21:17-23.
    In the beginning of the 20th century the groundbreaking work of Ramon y Cajal firmly established the neuron doctrine, according to which neurons are the basic structural and functional units of the nervous system. Von Weldeyer coined the term “neuron” in 1891, but the huge leap forward in neuroscience was due to Cajal’s meticulous microscopic observations of brain sections stained with an improved version of Golgi’s la reazione nera (black reaction). The latter improvement of Golgi’s technique made it possible to (...)

    Enhancing User Creativity: Semantic Measures for Idea Generation.Georgi V. Georgiev & Danko D. Georgiev - 2018 - Knowledge-Based Systems 151:1-15.
    Human creativity generates novel ideas to solve real-world problems. This thereby grants us the power to transform the surrounding world and extend our human attributes beyond what is currently possible. Creative ideas are not just new and unexpected, but are also successful in providing solutions that are useful, efficient and valuable. Thus, creativity optimizes the use of available resources and increases wealth. The origin of human creativity, however, is poorly understood, and semantic measures that could predict the success of generated (...)

    Hans Albert a Problém Hodnotové Neutrality Vědy.Jitka Paitlová - 2013 - Teorie Vědy / Theory of Science 35 (3):381-396.
    Studie pojednává o analýze a navrhovaném řešení problému „hodnotové neutrality" vědy německým kritickým racionalistou Hansem Albertem. Především Albert odmítá dvě vyhrocené pozice: novopozitivistickou ignoraci hodnotících soudů i jejich existencialistickou adoraci. Naopak se prostřednictvím takzvaných přemosťovacích principů snaží překlenout propast mezi poznáním na jedné straně a rozhodnutím na straně druhé. V návaznosti na Maxe Webera uznává princip hodnotové neutrality ve vědě, ovšem pouze v oblasti jejího objektového jazyka, neboť věda jako technologický systém výpovědí má pouze informativní, nikoli normativní charakter. To však (...)

    Nevidí ten, Kdo Se Jen Dívá.Jindřich Černý - 2012 - Teorie Vědy / Theory of Science 34 (2):189-200.
    Kuhn byl stoupencem tzv. „relativizovaného apriori". Apriori se nevyznačuje apodiktičností; zachovává si však stále konstitutivní funkci pro předmět poznání. Poznávající subjekty musí znát významy „paradigmatických propozic" proto, aby měli zkušenost. Zkušenost se neredukuje na vnímání. S Fleckem řečeno, pro vidění je dívání se jen nutnou, nikoli však dostatečnou podmínkou; je nadto nutné i vědět. Paradigmatické propozice se tak stávají podmínkou veškerého poznání, které je jimi „nasyceno". Různým paradigmatům respektive teoriím proto odpovídají různé zkušenosti. Paradigmata však nejsou na zkušenosti zcela nezávislá. (...)

  13. Oko mysli: Agnes Arberová k otázce biologického hlediska.Matěj Pudil - 2018 - Teorie Vědy / Theory of Science 40 (1):107-126.
    Práce se zabývá filosofickou analýzou vědeckého výzkumu, kterou v polovině minulého století provedla botanička Agnes Arberová. Její koncepce je cenným příspěvkem k otázce kontextu vzniku vědeckého objevu a procesu jeho zdůvodnění v biologických disciplínách. Ve stati se pokusím doložit, že její úvahy mají ráz v zásadě fenomenologický, a proto bude její koncepce interpretována na pozadí úvah Maurice Merleau-Pontyho o tělesné povaze smyslů. Taková interpretace napovídá, že Arberová ve shodě s Merleau-Pontym uvažuje o fenoménech nikoli jako o objektech, které lze zkoumat (...)

    Aristotelés o panství: mezi Heideggerem a Gagarinem.Jakub Jinek - 2006 - Reflexe: Filosoficky Casopis 31:19-44.
    Je otrok podle Aristotela vykořisťovaným nástrojem výroby stojícím na úrovni zvířete, nebo méně nadaným jedincem, jenž může svoje omezené možnosti naplnit pouze jako podřízený člen domácnosti? Aristotelští badatelé zdůrazňují jednu z možností podle toho, nakolik jsou sami liberálně, či komunitaristicky orientováni: buď je Aristotelova teorie panství vykládána jako nelidská a ideologická, nebo jako realistická a solidární. Spor se však netýká pouze „liberalismu“ a „komunitarismu“ v Aristotelovi, nýbrž – jelikož je otrok v obou výkladech chápán jako nástroj pána – také dvou (...)
