  • A picture is worth a thousand words

    By Asha Gage, IET Archivist Photographs of people are ubiquitous. We are surrounded by them and they dominate social media where followers are encouraged to participate in commenting on ‘selfies’ and the environment. It is an engaging activity, one in which the viewer becomes part of the process, the object the subject too. However, photography and the sharing of images is nothing new. Each photograph taken has had an audience in mind and how we interpret those images can reveal much of society’s conventions. The science behind the image It is not the purpose of this blog to discuss the inventor of photography as many can lay claim to this accolade. But for simplicity’s sake Louis Daguerre developed the daguerreotype process in 1839. The metal-based daguerreotype came in to competition…

  • The Tech Time Traveler: Decades of change in one career

    When Richard Baker looks back on his decades-long career, one theme stands out: adaptability. From designing fire detection systems in the 1970s to pioneering battery-powered trains in the 21st century, Richard’s journey reflects the rapid evolution of technology, and the mindset needed to thrive in it. Early Days: From Programming to Fire Safety Richard began his professional life with a brief foray into computer programming. “With hindsight, maybe I should have stuck with it,” he laughs. But his path soon shifted toward design engineering, joining a company that specialised in fire detection and gas extinguishing systems. This was a pivotal era. Microprocessors were starting to replace relays and transistors, and Richard found himself at the heart of this transformation. “It was a fascinating…

  • IP-based future? Optimising reach while sustaining trust and viability in broadcast & media distribution

    A century ago, on 26th January 1926, John Logie Baird gave his first public demonstration of television. Though crude by today’s standards due to flickering and being limited to a monochrome image transmitted across a room, it marked the beginning of the television we enjoy today. In previous articles, I highlighted the challenges faced by Public Service Media (PSM), particularly around funding. Only a handful of countries around the world have legislation for license fees, and even then, collecting them can be a tedious task. Despite these challenges, any publicly funded PSM should command the public’s trust, remain independent and accountable, and represent all communities across the country it operates in. Here, we analyse and discuss some of the strategies that, in my view, work well…

  • You can't be what you can't see: why your STEM story matters

    We often talk about the STEM skills gap, the lack of diversity in STEM, and the need to build a sustainable pipeline. But behind all these challenges sits something simple and profoundly human: representation. What we see around us shapes not only how we understand the world, but also how we understand our place in it. For many girls across the UK, STEM roles still feel distant, unrelatable, and “not for them”—and this continues to feed an unbalanced STEM workforce. The STEM skills gap costs the UK economy around £1.5 billion each year, yet women still represent just 27% of the STEM workforce. Increasing representation isn’t just socially important; it is a practical, evidence‑based way to boost innovation, strengthen teams, and address long‑term shortages. Why role models matter You…

  • ClimateTech, CleanTech, or DeepTech... Choose your own confusion!

    I spend a lot of time at engineering, innovation and sustainability events. The venues change. Sometimes it is a university lecture theatre. Sometimes it is a startup demo day. Occasionally it is a factory floor where everyone is wearing high-visibility jackets and nodding seriously at a machine that has been running perfectly well for years. What does not change... are the questions. Once the panel ends or the coffee arrives, someone inevitably asks me a version of the same thing. What do you actually mean by climate tech? Is clean tech the same thing as green tech? And where do deep tech and artificial intelligence fit into all of this? These are not naive questions. They are sensible ones. The fact that so many engineers ask them suggests we have a language problem, not a…

  • Volunteer Spotlight: Brian Goodwin

    In Conversation with... Eur Ing Brian Goodwin MSc. CEng. FIMechE. MIET. FCILT From apprentice to Chartered Engineer and international business leader, Brian’s career shows just how far engineering can take you. After a lifetime of roles spanning manufacturing, project delivery and senior leadership across the UK and overseas, retirement brought a new question — how to give something back to the profession that shaped his life. In this spotlight, Brian shares his journey and explains why volunteering, mentoring and supporting future engineers has become such a rewarding next chapter. “Retirement made me realise how much I missed being part of an engineering community.” I’m relatively new to volunteering. After a long and varied career crossing engineering, operations management and functional…

  • Exploring the minds of machines: from hand written digits to thinking in language.

    Artificial intelligence has become such a familiar part of our daily lives that many of us barely pause to wonder how it actually works. From photo apps that recognise faces to the large language models embedded in our productivity tools, AI is no longer a futuristic concept, it’s simply the landscape we live in. Last October, the IET Sussex Network set out to peel back some of that familiarity with a talk titled “How DO Machines Learn?” It offered a rare chance to go back to basics and explore what actually sits beneath the buzzwords. Rather than diving into complex, abstract theory, the session focused on one of the simplest, and most classic, examples of machine learning: teaching a computer to recognise hand‑written numbers. It’s a perfect illustration because it’s something humans…

  • Payloads of the Past: From Looking Up to Looking Down

    Previously we went on a journey aboard Cold War payloads that were designed to look up and out: Geiger counters hunting for trapped radiation belts; rendezvous kits rehearsing an orbital choreographed dance; and capsules containing a man’s best friend that explored the unknown so that humans could soon follow. This month we pivot from that urgency in orbit to a quieter revolution (arguably like my kids, getting louder everyday) unfolding below, as engineers and technologists learn to treat Earth itself as the most important “target” in the sky, from commercial and government (Defence) standpoints. Early weather and Earth‑observation payloads turned “looking down” from a curiosity into a strategic asset, changing not only how we understood the planet but also how nations planned, traded…

  • The 1953 North Sea Flood: A Turning Point in Coastal Engineering

    On the night of 31 January 1953, an extreme storm surge swept across the North Sea and left a mark on the engineering world that still shapes our thinking today. For many engineers, the 1953 North Sea flood is more than a historical event. It’s a case study in systems failure, cross‑border vulnerability, and the transformative power of engineering when society decides that “never again” must truly mean something. Although more than 70 years have passed, the flood continues to influence coastal defence design, risk modelling, data collection practices, and even community resilience strategies. For engineers, the 1953 flood serves as a powerful reminder of why our work matters. A Perfect Storm Meets Vulnerable Defences The disaster unfolded when a deep Atlantic depression moved southeast…

  • France Sparks Europe’s Tech Resilience Pivot

    Overview France has decided to stop treating “digital sovereignty” like a slogan and start treating it like a risk register. At the first Rencontres de la souveraineté numérique on 26 January 2026, Minister for Digital and AI Anne Le Hénanff launched two practical instruments: the Observatoire de la souveraineté numérique (entrusted to the Haut-commissariat à la Stratégie et au Plan) and the Indice de résilience numérique (IRN) , a private-sector initiative chaired by Olivier Sichel of the Caisse des Dépôts. The Minister’s framing was unusually direct: “La souveraineté commence par la lucidité… Nous devons savoir d’où et de quoi nous dépendons” (Sovereignty begins with clear-sightedness… We must know where and on what we depend). Reference : French Government Press Release, 26 January…

  • The Rise of Hybrid AI in Engineering

    Across engineering sectors, conversations about AI are shifting. Instead of debating whether AI is being over‑sold or under‑used, the discussion in engineering circles has moved toward something more concrete: how AI can be integrated into existing technical workflows in a way that aligns with engineering rigour, safety standards and domain knowledge. This shift has brought increasing attention to what many research groups, engineering bodies and industry case studies refer to as Hybrid AI. Hybrid AI blends machine‑learning models with symbolic or rule‑based systems, which includes engineering constraints, logic rules, knowledge graphs and physical models. The goal is not to replace engineering reasoning, but to create AI systems that operate in a structured, verifiable way consistent with…

  • Unveiling Video at a Distance - Television at 100

    Tuesday 26th January 1926, 22 Frith Street - 100 Years since the first public demonstration of a fully working Television system. That dateline was in the mind of the great and the good of the Royal Institution, who were invited to attend the first public demonstration of a working television system. Over 40 members turned up to see what many believed was not possible - literally the see it to believe it event - in the tiny attic rooms that comprised John Logie Baird's laboratory which was in a fairly nondescript London street. The public unveiling went to plan and showed what John Logie Baird had produced - an electromechanical television system that captured the moving image of a recognisable face on the camera, transmitted it the short distance to the receiver that then recreated the…

  • “As you cannot see on this slide”, a.k.a. The Information Density Problem

    Summary: The information density of professional-level training is often too high and, therefore, not conducive to learning. To create highly effective learning, we must define realistic expectations, start with the simplest possible framework, and progress slowly. Imagine that you’re at a typical conference. It’s been a full schedule and you have already seen several talks. Now you are in yet another presentation of post-doctoral level complexity and the speaker tells you “ as you can see in this slide… ”. You and everyone else in the room leans forward slightly, squints, and scans the slide quickly, hoping that what “ you can see ” will become visible. It doesn’t. Despite everyone’s efforts, among the text, charts, diagrams, and font size 6 annotations , which fill the slide, no one can…

  • Validating Vertical Corrector Magnets for HESR with COMSOL and Python

    In the realm of particle accelerators, precision in electromagnetic design is paramount. The High-Energy Storage Ring (HESR) at the Facility for Antiproton and Ion Research (FAIR) ( https://en.wikipedia.org/wiki/Facility_for_Antiproton_and_Ion_Research ) in Germany represents a cutting-edge project where normal-conducting magnets play a critical role in steering and correcting charged particle beams. As part of Romania's in-kind contribution to FAIR, the National Institute for R&D in Electrical Engineering ICPE-CA ( https://www.icpe-ca.ro/ ) manufactured a series of vertical corrector magnets. This blog explores the validation process for these magnets, emphasizing the electromagnetics principles involved and the pivotal role of Python in data analysis, complemented by COMSOL Multiphysics simulations…

  • 100 years of TV: To protect the enduring power of terrestrial television, do not let technology exceed humanity

    World Television Day 2025 was celebrated on November 21, honouring television’s enduring influence as a medium for information, education, entertainment, and shared experiences. This year’s theme, “ TV is Changing. Its Power Remains ,” highlighted the evolution of the medium from its earliest broadcasts to today’s smart screens, while reaffirming its role in connecting people and informing society. Established by the United Nations in 1996, the day recognises television’s growing impact on global decision-making and cultural milestones. According to the UN, television remains a powerful symbol of communication and globalisation in the modern world. In 1996, the United Nations convened the first World Television Forum, acknowledging television’s growing influence on global decision-making…

  • Simple steps to a healthier, happier year

    The new year can come hand in hand with pressure to overhaul your routine and improve your life. But research shows that it’s more sustainable to build small, consistent habits than to make drastic changes. Studies on behavioural change suggest that starting small, like adding one positive habit, increases the likelihood of success. If you’re wondering where to start, you could look to Blue Zones for inspiration. Blue Zones are regions of the world where people live longer, sometimes reaching 100 years and beyond, and enjoy better health along the way. Their secret isn’t extreme diets or intense exercise plans. People in Blue Zones share a handful of habits that support physical and mental wellbeing: They move regularly They eat whole foods, with diets rich in natural fats They…

  • Payloads of the Past: Explorer 1 – America’s First Orbiting Satellite

    A New Year, A Cold War Deadline (Do not Worry we are looking at 1958) It is January 1958; the United States has already watched Sputniks 1 and 2 cross the night sky and seen the Vanguard launch fail on live television. Confidence, at least in public, was wobbling.​ Into that gap stepped an Army–JPL team, leading this were a few legends of the industry, Wernher von Braun and James Van Allen (You know the belt? This is why), they were given a brutally tight schedule to field a complete launch vehicle and science payload in 90 days. The result? A slim, pencil‑like satellite only about 2m long, 16cm in diameter and 14kg. Perched atop a modified Redstone known as Juno I and cleared to fly from Cape Canaveral before the patience of Washington became untenable and programmes were closed.​ At…

  • The Future of British Switchgear

    Sulphur hexafluoride (SF₆) is one of the most potent greenhouse gases in use today, with a global warming potential approximately 24,300 times greater than carbon dioxide (CO₂) over a 100-year period. Despite being used in relatively small quantities, its environmental impact is significant. It is one of the 6 notified greenhouse gases in the F Gas regulations. Across Great Britain, electrical switchgear is estimated to contain around 1 million kg of SF₆ , spread across more than 200,000 units . Approximately 97% of these assets operate at distribution level , within medium and high voltage networks. For decades, SF₆ has delivered compact, reliable switchgear. Why SF₆ Became the Standard SF₆ offers unrivalled electrical insulation and arc‑quenching performance, allowing high-energy switching…
