David Hilderman has a Bachelor of Applied Sciences in Electronic Information Systems Engineering from the University of Regina and has worked in the electronics industry since graduation in 1988. David grew up in Saskatchewan, the second oldest in a family of six boys.  Since 2000 he has lived in beautiful Saanichton British Columbia, raising two great kids with his lovely wife. He went to the Victoria area to combine his engineering experience and love of music production to work for TC-Helicon, a company that makes products for performing musicians. He worked there for 19 years, five of which were in the role of Chief Operating Officer. Early 2020 he became aware of the fact that sea level rise rates were not accelerating.  In Victoria, the rate of rise has not changed over the entire record since 1909 and is only 0.75mm/yr.   This began his research in other climate alarmist claims.  Reality is so counter to the narrative and the consequences of acting on the narrative are so detrimental that he felt he needed to do something about it. In 2021 he ran in the federal election against the Green Party incumbent, Elizabeth May, and had the opportunity to debate her on the issue of climate five times. He continues to be active in his community, working to educate people on the benefits of increasing atmospheric CO2. 00:00 Introduction and Background 00:33 Understanding Carbon Dioxide Emissions 02:06 Historical Carbon Dioxide Levels 05:08 Impact of Increased Carbon Dioxide 09:26 Mathematical Analysis of Carbon Dioxide Absorption 15:50 Future Carbon Dioxide Emission Scenarios 28:42 Sea Level Rise and Climate Change 37:51 Personal Journey and Conclusion https://co2coalition.org/teammember/david-hilderman/ https://x.com/david_hilderman ———————— AI summaries of all of my podcasts (plus transcripts of recent podcasts): https://tomn.substack.com/p/podcast-summaries https://linktr.ee/tomanelson1 Twitter: https://twitter.com/TomANelson Substack: https://tomn.substack.com/ About Tom: https://tomnelson.blogspot.com/2022/03/about-me-tom-nelson.html Notes for climate skeptics: https://tomn.substack.com/p/notes-for-climate-skeptics ClimateGate emails: https://tomnelson.blogspot.com/p/climategate_05.html

George Boole fue un matemático, educador, lógico y filósofo británico nacido en Lincoln, Inglaterra, el 2 de noviembre de 1815. Es considerado uno de los fundadores de las ciencias de la computación por su invención del álgebra de Boole, un sistema de lógica matemática que utiliza símbolos para representar operaciones lógicas como la conjunción, la disyunción y la negación. Boole comenzó su educación formal en la escuela primaria de Lincoln, donde destacó en matemáticas. A la edad de 16 años, comenzó a estudiar por su cuenta matemáticas avanzadas y lógica. En 1835, publicó su primer libro, The Mathematical Analysis of Logic, en el que desarrolló sus ideas sobre la lógica matemática. En 1844, Boole fue nombrado profesor de matemáticas en la Queen's College de Cork, Irlanda. En este puesto, continuó desarrollando su teoría de la lógica matemática. En 1854, publicó su obra más importante, An Investigation of the Laws of Thought, en la que expuso su álgebra de Boole en detalle. El álgebra de Boole tuvo un impacto significativo en el desarrollo de las ciencias de la computación. Se utiliza en la actualidad para diseñar circuitos electrónicos, procesadores de datos y algoritmos de software. Boole murió en Ballintemple, Irlanda, el 8 de diciembre de 1864, a la edad de 49 años. A continuación, se presentan algunos de los logros más importantes de George Boole: Invención del álgebra de Boole, un sistema de lógica matemática que utiliza símbolos para representar operaciones lógicas.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.07.14.549062v1?rss=1 Authors: Usmani, I. M., Dijk, D.-J., Skeldon, A. C. Abstract: Accurate assessment of the intrinsic period of the human circadian pacemaker is essential for a quantitative understanding of how our circadian rhythms are synchronised to exposure to natural and man-made light-dark cycles. The gold standard method for assessing intrinsic period in humans is forced desynchrony (FD) which assumes that the confounding effect of light on assessment of intrinsic period is removed by scheduling sleep-wake and associated dim light-dark (LD) cycles to periods outside the range of entrainment of the circadian pacemaker. However, the observation that the mean period of free-running blind people is longer than the mean period of sighted people assessed by FD (24.50 +/- 0.17 h versus 24.15 +/- 0.20 h, p less than 0.001) appears inconsistent with this assertion. Here, we present a mathematical analysis using a parsimonious parametric model of the circadian pacemaker with a sinusoidal velocity response curve (VRC) describing the effect of light on the speed of the oscillator. The analysis shows that the shorter period in FD may be explained by exquisite sensitivity of the human circadian pacemaker to low light intensities and a VRC with a larger advance region than delay region. The main implication of this analysis, which generates new and testable predictions, is that current quantitative models for predicting how light exposure affects entrainment of the human circadian system may not accurately capture the effect of dim light. The mathematical analysis generates new predictions which can be tested in laboratory experiments. These findings have implications for managing healthy entrainment of human circadian clocks in societies with abundant access to light sources with powerful biological effects.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.09.11.293787v1?rss=1 Authors: Cone, I., Shouval, H. Z. Abstract: Traditional synaptic plasticity experiments and models depend on tight temporal correlations between pre- and postsynaptic activity. These tight temporal correlations, on the order of tens of milliseconds, are incompatible with significantly longer behavioral time scales, and as such might not be able to account for plasticity induced by behavior. Indeed, recent findings in hippocampus suggest that rapid, bidirectional synaptic plasticity which modifies place fields in CA1 operates at behavioral time scales. These experimental results suggest that presynaptic activity generates synaptic eligibility traces both for potentiation and depression, which last on the order of seconds. These traces can be converted to changes in synaptic efficacies by the activation of an instructive signal that depends on naturally occurring or experimentally induced plateau potentials. We have developed a simple mathematical model that is consistent with these observations. This model can be fully analyzed to find the fixed points of induced place fields, the convergence to these fixed points, and how these fixed points depend on system parameters such as the size and shape of presynaptic place fields, the animal's velocity, and the parameters of the plasticity rule.

The History of Computing
Boolean Algebra

The History of Computing

Boolean algebra Welcome to the History of Computing Podcast, where we explore the history of information technology. Because understanding the past prepares us to innovate (and sometimes cope with) the future! Today we're going to talk a little about math. Or logic. Computers are just a bunch of zeroes and ones, right? Binary. They make shirts about it. You know, there are 10 types of people in the world. But where did that come from? After centuries of trying to build computing devices that could help with math using gears that had lots of slots in them, armed with tubes and then transistors, we had to come up with a simpler form of logic. And why write your own complicated math when you can borrow it and have instant converts to your cause? Technical innovations are often comprised of a lot of building blocks from different fields of scientific or scholastic studies. The 0s and 1s, which make up the flip-flop circuits computers are so famous for, are made possible by the concept that all logic can be broken down into either true or false. And so the mathematical logic that we have built trillions of dollars in industry off of began in 1847 in a book called The Mathematical Analysis of Logic, by George Boole. He would follow that up in a book called An Investigation of the Laws of Thought in 1854. He was he father of what we would later call Boolean Algebra once the science of an entire mathematical language built on true and false matured enough for Charles Sanders Peirce wrote a book called The Simplest Mathematics and had a title called Boolian Algebra with One Constant. By 1913, there were many more works with the name and it became Boolean algebra. This was right around the time that the electronic research community had first started experimenting with using vacuum tubes as flip-flop switches. So there's elementary algebra where you can have any old number with any old logical operation. Those operators can be addition, subtraction, multiplication, division, etc. But in boolean algebra the only variables available are a 0 or a 1. Later we would get abstract algebra as well, but for computing it was way simpler to just stick with those 0s and 1s and in fact, ditching the gears from the old electromechanical computing paved the way for tubes to act as flip-flop switches, and transistors to replace those. And the evolutions came. Both to the efficiency of flip-flop switches and to the increasingly complex uses for mechanical computing devices. But they hadn't all been mashed up together. So set theory and statistics were evolving. And Huntington, Jevons, Schröder, basically perfected Boolean logic, paving the way for MH Stone to provide that Boolean algebra is isomorphic to a field of sets by 1936. And so it should come as no surprise that Boolean algebra would be key to the development of basic mathematical functions used on the Berry-Attansoff computer. Remember that back then, all computing was basically used for math. Claude Shannon would help apply Boolean algebra to switching circuits. This involved binary decision diagrams for synthesizing and verifying the design of logic circuits. And so we could analyze and design circuits using algebra to define logic gates. Those gates would get smaller and faster and combined using combinational logic until we got LSI circuits and later with the automation of the design of chips, VLSI. So to put it super-simple, let's say you are trying to do some maths. First up, you convert values to bits, which are binary digits. Those binary digits would be represented as a 0 or a 1, expressed in binary algebra as . There's a substantial amount of information you can pack into those bits, with all major characters easily allowed for in a byte, which is 8 of those bits. So let's say you also map your algebraic operators using those 0s and 1s, another byte. Now you can add the number in the first byte. To do so though, you would need to basically translate the notations from classical propositional calculus to their expression in Boolean algebra, typically done in an assembler. Much, much more logic is required to apply quantifiers. And simple true values are 0 and 1 but have a one step truth table to define AND (also known as a conjunction), OR (also known as a disjunction), and NOT XOR (also known as an exclusive-or). This allows for an exponential increase in the amount of logic you can apply to a problem. The act of deceasing if the problem satisfies the ability to translate into boolean capabilities is known as the Boolean satisfiability problem or SAT. At this point though, all problems really seem solvable using some model of computation given the amount of complex circuitry we now have. So the computer interprets information the functions and sets the state of a switch based on the input. The computer then combines all those trues and false into the necessary logic and outputs an answer. Because the 0s and 1s took too much the input got moved to punch cards, and modern programming was born. These days we can also add Boolean logic into higher functions, such as running AND for google searches. So ultimately the point of this episode is to explore what exactly all those 0s and 1s are. They're complex thoughts and formulas expressed as true and false using complicated Boolean algebra to construct them. Now, there's a chance that some day we'll find something beyond a transistor. And then we can bring a much more complicated expression of thought broken down into different forms of algebra. But there's also the chance that Boolean algebra sitting on transistors or other things that are the next evolution of boolean gates or transistors is really, well, kinda' it. So from the Barry-Attansoff computer comes Colossus and then ENIAC in 1945. It wasn't obvious yet but nearly 100 years after the development of Boolean algebra, it had been combined with several other technologies to usher in the computing revolution, setting up the evolution to microprocessors and the modern computer. These days, few programmers are constrained by programming in Boolean logic. Instead, we have many more options. Although I happen to believe that understanding this fundamental building block was one of the most important aspects of studying computer science and provided an important foundation to computing in general. So thank you for listening to this episode. I'm sure algebra got ya' totally interested and that you're super-into math. But thanks for listening anyways. I'm pretty lucky to have ya'. Have a great day

Markus Maier hat 2016 in der Arbeitsgruppe des Instituts für Angewandte und Numerische Mathematik am KIT promoviert, in der auch Gudrun arbeitet. Sein Thema war The Mathematical Analysis of a Micro Scale Model for Lithium-Ion Batteries. Wie der Name der Arbeit suggeriert, betrachtet er Modelle für Lithium-Ionen-Akkumulatoren (die englische Übersetzung ist für uns Deutsche etwas irreführend Batteries), die auf mikroskopischer Ebene die Stromabgabe über die elektrochemischen Eigenschaften vorhersagen können. Ausgangspunkt des Themas war der Wunsch Degradationsmechanismen - also die Alterung der Akkus - besser zu verstehen. Das Thema Strom speichern ist sehr wichtig und wird in Zukunft noch wichtiger werden. Simulationen sind hier nötig, da jedwedes Messen auf der Mikroskala unmöglich ist - es geht um Objekte von der Größe einiger Mikrometer. Das Ausweichen auf die besser durch Messungen begleitbare makroskopische Ebene im Modell ist nicht möglich, weil man nur auf der Ebene der Ionen die Abläufe nachbilden kann, die zur Alterung führen. Ein Beispiel für so einen Prozess ist, dass die Lithium Ionen nach der Wanderung durch das Elektrolyt in der Kathode auf Platzproblem treffen, die dazu führen können, dass die Katode beschädigt wird, wenn sich die Ionen den nötigen Platz verschaffen. Diese Beschädigungen führen zu Reduzierung der Kapazität. Leider ist die modellhafte Auflösung der ganzen Mikrostruktur einer Batterie numerisch noch unmöglich - weshalb die Untersuchung der Arbeit im Moment nur lokale Ergebnisse enthält. Die kristalline Struktur in der Kathode kann es auch ermöglichen, dass sich eine zweite Phase bildet, in der sich mehr Lithium-Partikel anlagern als ursprünglich Platz in der Kathode ist. Das führt auf ein 2-Phasen-Problem mit einem Phasenübergang. Der Rand zwischen den Phasen ist dann Teil der gesuchten Lösung des Problems. Dieser Teil ist im Moment noch nicht im Modell enthalten. Schließlich hat sich Markus darauf konzentriert, ein Kompromiss-Modell der Ingenieure zu untersuchen, das im Wesentlichen auf Erhaltungseigenschaften beruht. Es hat die Form eines Systems von zwei gekoppelten partiellen Differentialgleichungen für das elektrische Potential und die Lithium-Ionen-Verteilung, welche in den zwei aneinander grenzenden Gebieten gelten. Am Grenzübergang zwischen Elekrolyt und Lithium-Partikeln gilt eine nichtlinearen Gleichung. Die erste Frage ist: Wie sichert man die Existenz und Eindeutigkeit der Lösung? Die Struktur des Beweises erweist sich als hilfreich für das anschließend gewählte numerische Verfahren. Es nutzt die Monotonie des elektrischen Potentials aus. Die Argumente gelten allerdings nur für ein klein genug gewähltes Zeitintervall, weil ein konstanter Strom als Entaldungs-Randbedingung gewählt wurde (nur für kurze Zeiten realistisch). Für Modelle, die Degradation simulieren können, wären andere Randbedingungen nötig wie beispielsweise ein konstanter Widerstand. Ein Masterstudent hat mit dem Open Source Finite-Elemente-Solver deal.II das vorgeschlagene Verfahren im Rahmen seiner Abschlussarbeit programmiert und nachgewiesen, dass es funktioniert und die Resultate überzeugen können.
