These systems, often referred to as cyber-physical systems, blend physical infrastructure, such as power grids, with advanced control and automation technologies. Historically, this integration has roots in SCADA systems, which were among the first examples of distributed computing, and remains crucial for ensuring resilience and operational efficiency in today's energy networks.The Historical Foundations of Electrical Systems: The episode highlights key moments in the evolution of electrical infrastructure, from the early debates between alternating current (AC) and direct current (DC) to the development of distributed control in power systems. Ziegler discusses how early technological decisions and innovations shaped the global grid, setting the stage for the modern challenges of integrating renewable energy and decentralized energy systems.The Promise and Challenges of Nuclear Energy: Ziegler provides a balanced perspective on nuclear power, acknowledging its potential as a low-carbon energy source but highlighting challenges such as high costs, public fear, and the complexities of large-scale projects. He notes the emerging interest in modular reactors, which aim to reduce costs and improve scalability, but stresses that their real-world impact is still to be proven.The Role of Renewable Energy and Storage: A major focus is on the rapid advancements in renewable energy, particularly solar power, and the associated need for effective storage solutions. Ziegler explains the dramatic drop in costs for lithium-ion batteries, making short-term energy storage more viable. However, he underscores the ongoing challenge of developing affordable long-term and seasonal storage technologies to support a 100% renewable energy system.Data Centers as Emerging Energy Consumers: The growing demand for electricity from data centers, especially those supporting AI technologies, is a significant trend discussed in the episode. Ziegler points out that data centers could consume up to 8-9% of total electricity in regions like Europe and the U.S. by 2030, driven by the energy-intensive nature of AI computations. This shift necessitates innovative approaches to grid connectivity and efficiency.Decentralization vs. Centralization in Grid Design: The debate over centralized versus decentralized energy systems is a recurring theme. Ziegler explains how historical constraints on communication bandwidth led to resilient, distributed architectures in power grids. He advocates for hybrid systems that balance centralized control with localized decision-making, drawing inspiration from biological systems like the human body for their adaptability and resilience.The Global Energy Transition and Geopolitical Risks: The episode explores the geopolitical dimensions of the energy transition, including dependencies on materials like lithium and solar panel production concentrated in regions like China. Ziegler argues that while local renewable energy generation reduces reliance on external energy sources, the global supply chain for components remains a vulnerability. He also emphasizes the need for greater resilience and strategic planning to navigate potential disruptions.

Bolis Ibrahim is the president of Cence Power, a start-up that aims to stop energy waste when AC power is converted to DC. The power coming into your house or office is AC, or alternating current. However, the vast majority of the devices and lights you use are DC, or direct current. Currently (har har), each individual device does its own AC/DC conversion, and if you've ever felt a hot laptop charger, you'll have witnessed power going to waste. Cence can save buildings up to 40% on their energy consumption for lighting and HVAC systems, which adds up when you consider how many commercial buildings there are in the world! ➡️ https://www.cencepower.com/ ➡️ Highlights: https://rosspalmer.com/bolis-ibrahim ➡️ Follow me on Instagram: @therosspalmer ➡️ Subscribe on YouTube: @therosspalmer

Abstract: Background: The aftereffects of transcranial alternating current stimulation (tACS), especially targeting occipital alpha oscillations, have been reported to show large individual differences in behavioural effects and neural responsiveness. We predicted that this variance at least partly originates from the fact that multiple alpha components are affected differently by alpha-tACS. Objective: To test the above prediction, we decomposed several alpha components from the data and evaluated the aftereffects separately for each component and participant. More specifically, we tested how the difference between the stimulation frequency and peak frequency influences the aftereffects of tACS on each alpha component. Methods: Eighteen participants received 20-min tACS or sham stimulation on separate days. Ten minutes of magnetoencephalography data were collected before and after stimulation, and spectral analysis was performed with a high-frequency resolution (0.1 Hz) to disentangle different alpha components based on the difference in peak frequencies and spatial patterns. Results: The results revealed three alpha components with slightly different frequencies. tACS increased or decreased the power of these alpha components depending on the relative frequency difference from electrical stimulation. Furthermore, observable components differed among participants, possibly because of anatomical differences in each alpha source. Conclusion: When each alpha component is not analysed separately, the change in overall alpha power will be a combination of decreased or increased components, and inter-individual differences will become larger. Our study highlights the importance of noting the presence of multiple alpha components with relatively small differences in the peak frequency for experimental design and analysis.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2022.11.15.516556v1?rss=1 Authors: Pariz, A., Trotter, D., Hutt, A., Lefebvre, J. Abstract: Transcranial alternating current stimulation (tACS) represents a promising non-invasive treatment for an increasingly wide range of neurological and neuropsychiatric disorders. The ability to use periodically oscillating electric fields to non-invasively engage neural dynamics opens up the possibility of recruiting synaptic plasticity and to modulate brain function. However, despite consistent reports about tACS clinical effectiveness, strong state-dependence combined with the ubiquitous heterogeneity of cortical networks collectively results in high outcome variability. Introducing variations in intrinsic neuronal timescales, we explored how such heterogeneity influences stimulation-induced change in synaptic connectivity. We examined how spike timing dependent plasticity, at the level of cells, intra- and inter-laminar cortical networks, can be selectively and preferentially engaged by periodic stimulation. Using computational simulations informed by human experimental data, we analyzed cortical circuits comprised of multiple cell-types, alongside superficial multi-layered networks expressing distinct layer-specific timescales. Our results show that mismatch in neuronal timescales within and/or between cells - and the resulting variability in excitability, temporal integration properties and frequency tuning - enables selective and directional control on synaptic connectivity by tACS. Our work provides new vistas on how to recruit neural heterogeneity to guide brain plasticity using non-invasive stimulation paradigms. Copy rights belong to original authors.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2022.11.03.515008v1?rss=1 Authors: Potok, W., van der Groen, O., Sivachelvam, S., Baechinger, M., Frohlich, F., Kish, L. B., Wenderoth, N. Abstract: Stochastic Resonance (SR) describes a phenomenon where an additive noise (stochastic carrier-wave) enhances the signal transmission in a nonlinear system. In the nervous system, nonlinear properties are present from the level of single ion channels all the way to perception and appear to support the emergence of SR. For example, SR has been repeatedly demonstrated for visual detection tasks, also by adding noise directly to cortical areas via transcranial random noise stimulation (tRNS). We mathematically show that high-frequency, non-stochastic, periodic signals can yield resonance-like effects with linear transfer and infinite signal-to-noise ratio at the output. Here we tested this prediction empirically and investigated whether non-random, high-frequency, transcranial alternating current stimulation (hf-tACS) applied to visual cortex could induce resonance-like effects and enhance performance on a visual detection task. We demonstrated in 28 participants that applying 80 Hz triangular-waves or sine-waves with hf-tACS reduced visual contrast detection threshold for optimal brain stimulation intensities. The influence of hf-tACS on contrast sensitivity was equally effective to tRNS-induced modulation, demonstrating that both hf-tACS and tRNS can reduce contrast detection thresholds. Our findings suggest that a resonance-like mechanism can also emerge when non-stochastic electrical waveforms are applied via hf-tACS. Copy rights belong to original authors.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2022.10.17.512611v1?rss=1 Authors: Geffen, A. R., Bland, N., Sale, M. V. Abstract: Transcranial alternating current stimulation (tACS) has been proposed to modulate neural activity through two primary mechanisms: entrainment and neuroplasticity. The current study aimed to probe both of these mechanisms in the context of the sensorimotor -rhythm using transcranial magnetic stimulation (TMS) and electroencephalography (EEG) to assess entrainment of corticospinal excitability (CSE) during stimulation (i.e., online) and immediately following stimulation, as well as neuroplastic aftereffects on CSE and EEG power. Thirteen participants received 3 sessions of stimulation. Each session consisted of 90 trials of -tACS tailored to each participants individual frequency (IMF), with each trial consisting of 16 seconds of tACS followed by 8 seconds of rest (for a total of 24 minutes of tACS and 12 minutes of rest per session). Motor evoked potentials (MEPs) were acquired at the start and end of the session (n = 41) and additional MEPs were acquired across the different phases of tACS at 3 epochs within each tACS trial (n = 90 for each epoch): early online, late online, and offline echo. Resting EEG activity was recorded at the start, end, and throughout the tACS session. The data were then pooled across the three sessions for each participant to maximise the MEP sample size per participant. We present preliminary evidence of CSE entrainment persisting immediately beyond tACS and have also replicated the plastic CSE facilitation observed in previous -tACS studies, thus supporting both entrainment and neuroplasticity as mechanisms by which tACS can modulate neural activity.

Abstract: Insufficient sleep is a major health issue. Inadequate sleep is associated with an array of poor health outcomes, including cardiovascular disease, diabetes, obesity, certain forms of cancer, Alzheimer's disease, depression, anxiety, and suicidality. Given concerns with typical sedative hypnotic drugs for treating sleep difficulties, there is a compelling need for added alternative interventions. Here, we report results of a non-invasive electrical brain stimulation approach to optimizing sleep involving transcranial alternating current stimulation (tACS). A total of 25 participants (mean age: 46.3, S.D. +/-12.4, 15 females) were recruited for a null-stimulation controlled (Control condition), within subjects, randomized crossed design, that included two variants of an active condition involving 15 minutes pre-sleep tACS stimulation. To evaluate the impact on sleep quality, the two active tACS stimulation conditions were designed to modulate sleep-dependent neural activity in the theta/alpha frequency bands, with both stimulation types applied to all subjects in separate sessions. The first tACS condition used a fixed stimulation pattern across all participants, a pattern composed of stimulation at 5Hz and 10Hz. The second tACS condition used a personalized stimulation approach with the stimulation frequencies determined by each individual's peak EEG frequencies in the 4-6Hz and 9-11Hz bands. Personalized tACS stimulation increased sleep quantity (duration) by 22 minutes compared to a Control condition (p=.04), and 19 minutes compared to Fixed tACS stimulation (p=.03). Fixed stimulation did not significantly increase sleep duration compared to Control (mean: 3 minutes; p=0.75). For sleep onset, the Personalized tACS stimulation resulted in reducing the onset by 28% compared to the Fixed tACS stimulation (6 minutes faster, p=.02). For a Poor Sleep sub-group (n=13) categorized with Clinical Insomnia and with a high insomnia severity, Personalized tACS stimulation improved sleep duration by 33 minutes compared to Fixed stimulation (p=0.02), and 30 minutes compared to Control condition (p less than 0.1). Together, these results suggest that Personalized stimulation improves sleep quantity and time taken to fall asleep relative to Control and Fixed stimulation providing motivation for larger-scale trials for Personalized tACS as a sleep therapeutic, including for those with insomnia.

Christine Ann Olivas Former homeschooled Fundamentalist. Marketer. Comic, storyteller, writer. Creator: 7 shows. Founder: @offmiccomedyschool From her Fundamentalist Christian, homeschooled upbringing to her liberal arts education in California, Christine's life has been a study in extremes. But whether we're talking organized religion or modern media, Christine insists on asking provocative, important questions about the ideas and practices we take for granted. Especially if they negatively affect women, body image, and sex. Christine started her arts journey as a fiction writer, with short stories focused on on the intersection of gender, sex, and technology. She gives us complex female characters that are both longing for more and self-isolating in a world that doesn't seem to understand them or want them to exist. Her short fiction has been published in Vol. 1 Brooklyn, Paper Darts, Breakwater Review, Alternating Current, Aptly, and on Catapult Community. She is also currently working on a full-length book about her life that will combine personal essay and memoir. When Christine relocated to Philly in 2018, she began studying and performing two new art forms: first-person storytelling and standup comedy. Since then, she has performed on local comedy/storytelling shows (Tell Me a Story, Comedy Incarnate, Story Hole, and Pass the Mic, to name a few) and at established venues in Philly (Punchline, Good Good Comedy Theatre, Philly Improv Theater), Tempe, Las Vegas, and NYC (Greenwich Village Comedy Club, Broadway Comedy Club). Christine is also a talented, visionary show producer in her own right, creating and hosting comedy shows that equally benefit performers and venues — while thoroughly engaging audiences. After creating Jenkintown's first comedy showcase, she now hosts “The Afternoon After,” Philly's first and only daytime open mic. She is also the brain behind and co-producer of “No Mo' Sexual FOMO,” a monthly experience combining standup and sex education. Since the pandemic began, Christine has quickly pivoted to taking standup comedy online. Already, she has produced and hosted a recurring virtual roast battle called Doomsday, two editions of Fools for Good (which benefits Philly venues, performers and non-profits), and is working on a virtual edition of No Mo' Sexual FOMO.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.11.19.387407v1?rss=1 Authors: Meng, A., Kaiser, M., de Graaf, T., Duecker, F., Sack, A. T., de Weerd, P., van de Ven, V. Abstract: Neural oscillations in the theta range (4-6 Hz) are thought to underlie associative memory function in the hippocampal-cortical network. While there is ample evidence supporting a role of theta oscillations in animal and human memory, most evidence is correlational. Non-invasive brain stimulation (NIBS) can be employed to modulate cortical oscillatory activity to influence brain activity, and possibly modulate deeper brain regions, such as hippocampus, through strong and reliable cortico-hippocampal functional connections. We applied high-definition transcranial alternating current stimulation (HD-tACS) at 6 Hz over left parietal cortex to modulate brain activity in the putative cortico-hippocampal network to influence associative memory encoding. After encoding and brain stimulation, participants completed an associative memory and a perceptual recognition task. Results showed that theta tACS significantly decreased associative memory performance but did not affect perceptual memory performance. These results show that parietal theta tACS modulates associative processing separately from perceptual processing, and further substantiate the hypothesis that theta oscillations are implicated in the cortico-hippocampal network and associative encoding.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.10.16.342105v1?rss=1 Authors: Schwab, B. C., König, P., Engel, A. K. Abstract: Background: Transcranial alternating current stimulation (tACS), applied to two brain sites with different phase lags, has been shown to modulate stimulation-outlasting functional connectivity between the targeted regions. Objective: Here, we test if spike-timing-dependent plasticity (STDP) can explain stimulation-outlasting connectivity modulation by dual-site tACS and explore the effects of tACS parameter choices. Methods: Networks with two populations of spiking neurons were simulated. Synapses between the populations were subject to STDP. We re-analyzed resting-state EEG data to validate the model. Results: Simulations showed stimulation-outlasting connectivity changes between in- and anti-phase tACS, dependent on both tACS frequency and conduction delays. Importantly, the model predicted that the largest effects would occur for short conduction delays between the stimulated regions, which agreed with experimental EEG connectivity modulation by 10Hz tACS. Conclusions: STDP can explain connectivity aftereffects of dual-site tACS. However, not all combinations of tACS frequency and application sites are expected to effectively modulate connectivity via STDP. We therefore suggest using appropriate computational models and/or EEG analysis for planning and interpretation of dual-site tACS studies relying on aftereffects.

Abstract: Recent evidence suggests that reward prediction errors (RPEs) play an important role in declarative learning, but its neurophysiological mechanism remains unclear. Here, we tested the hypothesis that RPEs modulate declarative learning via theta-frequency oscillations, which have been related to memory encoding in prior work. For that purpose, we examined the interaction between RPE and transcranial Alternating Current Stimulation (tACS) in declarative learning. Using a between-subject (real versus sham stimulation group), single-blind stimulation design, 76 participants learned 60 Dutch-Swahili word pairs, while theta-frequency (6 Hz) tACS was administered over the medial frontal cortex (MFC). Previous studies have implied MFC in memory encoding. We replicated our previous finding of signed RPEs (SRPEs) boosting declarative learning; with larger and more positive RPEs enhancing memory performance. However, tACS failed to modulate the SRPE effect in declarative learning and did not affect memory performance. Bayesian statistics supported evidence for an absence of effect. Our study confirms a role of RPE in declarative learning, but also calls for standardized procedures in transcranial electrical stimulation. Copy rights belong to original authors.

Abstract: Alpha oscillations (8-13 Hz) have been shown to play an important role in dynamic neural processes underlying learning and memory. The goal of this study was to scrutinize the role of oscillations for communication within the network implicated in motor sequence learning. To this end, we conducted two experiments using the serial reaction time task. In the first experiment, we explored changes in power and cross-channel coherence shortly before the motor response. We found a gradual decrease in learning-related power over left premotor cortex (PMC) and somatosensory areas. Connectivity between left PMC and right cerebellum was reduced for sequence learning, possibly reflecting a functional decoupling in the premotor-cerebellar loop during the motor learning process. In the second experiment in a different cohort, we applied 10Hz transcranial alternating current stimulation (tACS), a method shown to entrain local oscillatory activity, to left M1 (lM1) and right cerebellum (rCB) during sequence learning. We observed learning deficits during rCB tACS compared to sham, but not during lM1 tACS. In addition, learning-related power following rCB tACS was increased in PMC, possibly reflecting a decrease of neural activity. Importantly, learning-specific coherence between left PMC and a right cerebellar cluster was enhanced following rCB tACS. These findings suggest that interactions within a premotor-cerebellar loop, which are underlying motor sequence learning, are mediated by oscillations. We show that they can be modulated through external entrainment of cerebellar oscillations, which modulates motor cortical and interferes with sequence learning.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.06.16.154112v1?rss=1 Authors: May, E. S., Hohn, V. D., Nickel, M. M., Tiemann, L., Gil Avila, C., Heitmann, H., Sauseng, P., Ploner, M. Abstract: Pain protects the body. However, pain can also occur for longer periods without serving protective functions. Such chronic pain conditions are difficult to treat. Thus, a better understanding of the underlying neural mechanisms and new approaches for the treatment of pain are urgently needed. Here, we investigated a causal role of oscillatory brain activity for pain and explored the potential of transcranial alternating current stimulation (tACS) as a new treatment approach for pain. To this end, we investigated whether tACS can modulate pain and pain-related autonomic activity in 29 healthy human participants using a tonic heat pain paradigm as an experimental model of chronic pain. In 6 recording sessions, participants received tACS over prefrontal or somatosensory cortices at alpha or gamma frequencies or sham tACS. During tACS, pain ratings and autonomic responses were collected. TACS did not modulate pain intensity, the stability of pain ratings or the translation of the noxious stimulus into pain. Likewise, tACS did not change autonomic responses. Bayesian statistics further indicated a lack of tACS effects in most conditions. The only exception was alpha tACS over somatosensory cortex where evidence for tACS effects was inconclusive. Taken together, the present study did not find significant tACS effects on tonic experimental pain in healthy human participants. However, considering the conceptual plausibility of using tACS to modulate pain and the urgent need for novel pain treatments, further tACS studies are warranted. Based on the present findings, such studies might apply refined stimulation protocols targeting alpha oscillations in somatosensory cortices. Copy rights belong to original authors.

Nikola Tesla's life continues to astound many people. Join me as I discuss Nikola Tesla's life and legacy with acclaimed Tesla biographer Marc Seifer. How was the uncle of President Donald J. Trump connected to Tesla? What did Nikola Tesla communicate with Joseph Stalin about during World War II? Did Nikola Tesla develop a "Death Ray?" Find out the answers to these questions in the inaugural episode of Alternating Current!

Foundations of Amateur Radio One of the things I love most about this hobby is the ability to randomly dart off into any related direction and learn new stuff. For example, the names Nikola, Guglielmo, Heinrich and Edwin emblazoned on a t-shirt sent to me by a very appreciative listener Jack KI4KEP, started an exploration into the deeds and misdeeds of the people behind those names. The first three might be somewhat familiar, Nikola Tesla whom we have to thank for inventions like Alternating Current, the Tesla coil, wireless power, radio remote control and many others. The Tesla company is named as a tribute to him. The magnetic flux density uses the letter T as its symbol and its called the Tesla. As a side note, if you've ever struggled to decide if a symbol needs to be a capital letter or not, like say the V for volt, the A for ampere, the O for ohm, the m for meter, the s in second or the K in kelvin, you just need to remember that if the unit is named after a person, the symbol needs to be a capital letter. That does assume that you know that the unit is named after an actual person, like say the Earl of Sandwich. Name two in our list, Guglielmo Marconi is the person whom we can thank for the practical development of radio communication, using improved spark-gap transmitters, the development and commercialisation of long-distance radio transmissions and his association with many other services such as a transatlantic radio-telegraph service, providing communications to shipping such as Jack Phillips and Harold Bride who were employed by the Marconi International Marine Communication Company to act as radio operators on the RMS Titanic on its fateful voyage. Our third name, Heinrich comes into sharp focus when I add his surname, Hertz. His name continues on in our day-to-day language and Heinrich Hertz is responsible for validating many of the underlying principles of our hobby. Using a spark-gap transmitter he was the first to conclusively prove the existence of electromagnetic waves which were predicted by James Clerk Maxwell. He also came up with the parabolic antenna, the dipole antenna, measurement of electric field intensity, electromagnetic waves and many other experiments. If you've ever seen a bullet hole in glass, you've seen a Hertzian cone. The last name had me stumped. It took a question to learn that Edwin shares a name with a famous cyclist and a famous astronaut, namely Armstrong. Edwin Howard Armstrong has been called "the most prolific and influential inventor in radio history". If you're like me you may not have heard of Edwin Armstrong. You might be surprised to learn that he's responsible for the regenerative circuit, the super-heterodyne circuit and while he was working on defending his invention against a claim made by a patent attorney he stumbled on the super-regeneration circuit. If you're a radio amateur, you'll likely have heard those terms, if not, they're electronic circuits that make radio receivers more sensitive which forms the basis of many radios in use today. My Yaesu FT-857d is a super-heterodyne radio for example. It doesn't stop there. The biggest claim to fame that Edwin Armstrong brings to the table is the invention of FM radio. It took many years and a protracted lawsuit that lasted until almost a year after he died to finally have Armstrong formally established as the inventor of FM. Not for a minute will I suggest that my exploration was comprehensive or in-depth, but it made my day when I put on a t-shirt with the names of those inventors who made it possible for me to be here and share this with you today. On the shoulders of giants wearing a t-shirt with their names I stand. I'm Onno VK6FLAB

Nikola Tesla changed the world by powering the world with Alternating Current by inventing the first Dynamo to use AC.With a high functioning, eidetic memory, Nikola was able to memorize everything in high detail, learned 8 languages and fought in the "War of the Currents" against Thomas Edison for the rights to power U.S. cities with his inventions.Come dive into the amazing life of the man who invented the 20th century!

Wagner Electric was a company based on the premise that the future lay with alternating current."The problem of course with direct current is it will kill you really quickly and alternating current is a much better option." said Dr. Robert Archibald.Their first location was a store front near 18th and Olive. It quickly grew and so did the size of its products. Which later included transformers."Wagner Electric survived the depression and went on into the 1950's and 60's. They eventually were purchased by Studebaker Corporation believe it or not and they still exist as a subsidiary of another larger company but their product line expanded from electric motors and related materials to automotive parts." said Dr. Robert Archibald of the Missouri History Museum.By the late 1930's Wagner employed 5,000 people. St. Louis based Emerson Electric also began with small electric motors. Wagner and Emerson had numerous plants and did business world wide.Unlike Emerson, which has a long history of buying other companies, Wagner was on the other end of that proposition. But, its new owners decided to keep Wagner's familiar name.

Summary Q 1. Should we celebrate Columbus Day? A. Of course. The opening of the Americas to European countries was a monumental development. Q 2. Was Christopher Columbus intelligent, courageous, and dedicated to his beliefs and goals despite years of rejection?  A. Yes. All three, and at levels that allowed him to play a pivotal role in history. Q 3. Was Columbus a deeply flawed man, who savaged the indigenous populations? A. Yes, he was deeply flawed. As was every great man or woman in history. Every last one. Experts in various fields correctly say that we need to deal with people and communities in a holistic way. I agree; let’s start with people like Columbus, FDR, JFK, Edison and many others in exactly that way. Let’s not be dishonest and portray only one side of the men and women who have shaped our country and the world. Presenting only one side--it does not matter which one one--to further an agenda is wrong and qualifies people as truth-twisters. A term we used in the last podcast, Profiling.

Presenting only one side--it does not matter which one one--to further an agenda is wrong and qualifies people as truth-twisters. A term we used in the last podcast, Profiling. Let’s jump right into the deep end of this pool by bringing up Martin Luther King, Jr. Dr. King, born in Atlanta in 1929, is a genuine American hero. In 1964, he won the Nobel Peace Prize for combating racial inequality through nonviolent resistance. And he helped to reshape how we think about and deal with race in our country, with worldwide reverberations. And he was a known plagiarist and a serial adulterer. That makes him human, and still very much a man well worth remembering and celebrating. Thomas Edison, born in 1847, is known as the inventor of the light bulb. He also invented the phonograph and the motion picture along the way to being granted 1,093 patents. He founded one of America’s most successful companies, General Electric--GE. He was also a proponent of Direct Current, DC, as opposed to Alternating Current, AC. He fought vigorously, and often unfairly, to promote DC over AC. Had he won, the electric grid that in so many ways helped to build and supports the US would have been greatly delayed. And, yes, this flawed human deserves to be greatly honored for his many vital contributions. Golda Meir, born in 1898, was the fourth prime minister of Israel. On her way to earning the unofficial title of “Iron Lady” well before Margaret Thatcher, the founding Israeli prime minister, David Ben-Gurion, called her “the best man in government.” She rallied her country after the horrific murders of Israeli athletes by appealing to the world to “save our citizens and condemn the unspeakable criminal acts committed.” She also had to resign after the crucial 1973 Yom Kippur War; her coun...

Nikola Tesla. The prototypical "mad scientist". He slept only a few hours a night and devoted his life to science like none-other. A rags-to-riches-to-rags visionary who was a giant in the field of scientific invention, he created the first alternating current (AC) motor and was a pioneer in the field of wireless information transmission. He helped build the world’s first large-scale hydroelectric power plant at Niagara Falls. He even pushed scientific rival Thomas Edison into electrocuting pets to prove that his direct current technology was better and safer than Tesla’s alternating current. It was a AC versus DC, War of Currents nerd fight that lasted over a decade. He was also a strange man who fell in love with a pigeon and once claimed to have created a "death ray".

So why would this need to be put in the NEC? Let’s just get into a little electrical theory for a minute. When alternating current (ac) flows through a conductor, a magnetic field is created around that conductor which is constantly expanding and contracting with the amplitude of the current. You know that the amplitude in the US is at a frequency of 60 cycles per second or 60 Hz. Now, since Alternating Current reverses polarity 120 times per second, it stands to reason that the magnetic field also reverses its direction….. 120 times per second. So why does that matter? Simple, the expanding and collapsing of the magnetic field induces something called eddy currents in the ferrous metal parts that surround the conductors. --- Support this podcast: https://anchor.fm/stuff-electricians-should-know/support

Foundations of Amateur Radio When you use your trusty multi-meter to measure resistance across a 50 Ohm resistor, it shows 50 Ohm, but when you use it across a piece of 50 Ohm coax, you see either infinity, or 0. Similarly, when you measure across a folded-dipole, you see 0, not 300 Ohm. Does this mean that a 50 Ohm resistor is somehow different than a 50 Ohm piece of coax and why is the feed-point impedance of a folded dipole 300 Ohm, when your multi-meter clearly says it's 0? Does this mean that there are two types of Ohm? Today I'm going to explain why this is and what's going on. Yesterday I started reading up on the subject and every single explanation I came across went into deep ju-ju with scary maths, using complex and imaginary numbers. I did a bit of that in my dark past, but none of that is needed to understand what's happening. As you know, there is such a thing as Direct Current or DC - we use it with batteries and little power supplies, in simple circuits and all manner of day-to-day activities. There is another world that we as amateurs use, the world of Alternating Current or AC. In house-hold wiring we use 50 or 60 Hertz and different voltages depending on where on the globe we are. In radio terms we use it for our transmissions, on HF at several Mega Hertz and beyond. These two different worlds, the DC and AC world don't appear to have anything in common. Here's the kicker though, they are the same thing. Yup. DC and AC are the same thing. What? Yup. I'm not making this up. As you might recall, if you look at an AC voltage, it goes from plus to minus and back again. A 50 Hertz alternating current does this swap 50 times per second. When you're rag-chewing on 40m, or 7 MHz, it happens 7 million times a second. From plus to minus and back, 7 million times. Clearly there has to be some impact on this massive level of activity. Think of direct current as an alternating current with a frequency of 0 Hertz, that is, over time, DC doesn't change. So, DC is a short cut for saying AC at 0 Hertz. If you understand that explanation, then some really cool stuff starts to happen. Before I get to the cool stuff, you might recall Ohm's Law, commonly expressed as: "Given a current and a resistance, we can determine a voltage". Said in another way, the resistance of a circuit is related to the voltage and the current in the circuit. Now, in this simple form of Ohm's Law, the voltage doesn't change from plus to minus and back again. That is, over time, there is no change. Now if you start doing funky stuff with your voltage, like change it from plus to minus and back again, an additional type of resistance comes into play, called reactance. This reactance is the part that is affected by voltage change over time. So if you swap the voltage from plus to minus and back again a million times a second, the reactance has a big part to play. In short, there are two types of resistance, one that is independent of time, called resistance, and one that's dependent on time, called reactance. Both of these, resistance and reactance, happen within a circuit. If the voltage doesn't change over time, then the reactance part is zero and similarly there are circumstances where you can have a resistance of zero but have a reactance that's not - one example is a folded dipole. Now, if you combine the resistance and reactance, you get something called impedance. Now you have all the bits. Resistance is expressed in Ohm, Impedance is expressed in Ohm, and thus Reactance is also expressed in Ohm. If we look at our folded dipole with a feed-point impedance of 300 Ohm, you now know that this 300 Ohm comes from a resistance of 0 Ohm and a reactance of 300 Ohm at the resonant frequency, which is why your trusty multi-meter shows it as 0, since the voltage it uses to measure is alternating at 0 Hertz, which is not the resonant frequency of this antenna. Before I go, the rabbit hole goes deeper. Reactance itself is made up of Capacitance and Inductance, which each deal with the reactance in a capacitor and an inductor, but I'll leave that for another day. So, next time someone tells you that the feed-point impedance of your folded dipole is 300 Ohm, you'll now understand why your multi-meter says it's 0. I'm Onno VK6FLAB.

What use is an F-call? From DC to Daylight is a term that until I became an Amateur, I'd never heard of and since becoming licensed I've bumped into it more than a couple of times. Once you sit and think about it, the notion, from DC to Daylight makes perfect sense, but what does it mean? I'll start off with that I'm not talking about Cheap Therapy for your Inner Problem Child - the Rock band based in San Jose, California. So, DC, or Direct Current, as opposed to AC, or Alternating Current does not change frequency, that is, the positive and negative poles never swap over, so the frequency that they switch at is 0Hz or zero times per second. If you reverse the poles, the frequency at which you do that, say flick a switch once every second, the frequency is 1Hz. AC does it 50 or 60 times per second, or 50 or 60 Hz. As you keep increasing the frequency, you'll come past 160m, just below 2MHz, 80m around 7MHz, etc, onto 2m around 145MHz, 70cm and up to WiFi at 2.4GHz, then 5.8GHz, eventually, you'll get to a frequency of around 400 THz, where you'll bump into visible light where the wavelength is 750nm. So, DC is 0Hz, Daylight is 400 THz, so from DC to Daylight means from 0 Hz to 400 THz. Said in another way, DC to Daylight means "all frequencies". Of course, you could point out that there are frequencies above daylight, indeed there are. It's really a short hand term and as amateur radio terms go, it's one of the more explanatory ones. Now all you need is a DC to Daylight radio, and you'll be able to listen to everything that goes on anywhere - provided you have an appropriately tuned antenna - Hi Hi. I'm sure there are terms you've come across that make no sense. Have a look around, or better still, contact another Amateur and work it out together. The only silly question is the one you didn't ask. I'm Onno VK6FLAB
