Charles Babbage And The First Computer

If you’ve ever wondered about the invention of computers, you might think of Alan Turing, and those massive banks of computers that sent the Apollo to the moon. But even by then the idea of a computer wasn’t exactly new. In the early 19th century, there was Charles Babbage—a man whose brilliant mind conceived the fundamental principles of modern computing, a good century before they became reality. There was just one slight problem: he was just a bit ahead of his time.

Babbage The Problem Solver

Born in 1791 in London, Charles Babbage was a clever bloke. He was a mathematician, inventor, and philosopher. From a young age, he was a bit of a prodigy, showing an insatiable curiosity and a knack for solving problems. By the time he attended Cambridge University, Babbage was already questioning the limitations of existing mathematical methods.

In the early 19th century, mathematical calculations were laboriously done by hand, often riddled with errors. It was all long division and chunking – no phones or calculator papers in your GCSEs back then. Babbage, frustrated by these inaccuracies, asked himself a revolutionary question: Could a machine do this work more reliably? From this question arose his first major invention: the Difference Engine.

Making A Difference… Engine

The Difference Engine (pictured) was designed to automate the production of mathematical tables, eliminating the errors inherent in manual calculation. Essentially, it was a calculator powered by steam, using gears and levers to perform those tricky calculations and keep track of all those ones to carry. Babbage envisioned it as a tool for astronomers, navigators, and engineers—anyone who relied on precise calculations.

Work on the Difference Engine began in 1822, with funding from the British government. However, the machine’s complexity soon became a stumbling block. With over 25,000 precision-engineered parts needed, the technology of the time simply couldn’t meet Babbage’s exacting standards. Sadly for Babbage, his project was eventually abandoned, unfinished, in 1833.

From Calculators To Computers

While the Difference Engine was impressive, it was the Analytical Engine that cemented Babbage’s place as the father of computing. Conceived in 1834, this machine wasn’t just a calculator—it was a general-purpose computer. The Analytical Engine had all the core components of a modern computer:

• A Mill: The equivalent of today’s CPU, it performed mathematical operations.
• A Store: A memory unit for holding numbers and intermediate results.
• Input and Output Devices: Punch cards would input data, and a printer would output results.
• Sequential Control: It could execute instructions in a specific order, akin to modern programming.

Perhaps the most remarkable feature of the Analytical Engine was its programmability. Babbage envisioned using punch cards, similar to those used in looms for weaving patterns into fabric, to instruct the machine. This meant it could solve a variety of problems, not just a single task—a revolutionary concept in the 1830s.

Charles Babbage Was His Own Worst Enemy

Despite his genius, Babbage’s perfectionism and constant tinkering meant that he never completed a single working model of either the Difference or Analytical Engine. Additionally, his difficult personality alienated potential supporters, and the British government eventually withdrew funding.

Another major obstacle was the technology of the time. Precision engineering in the 19th century wasn’t advanced enough to produce the intricate parts Babbage’s machines required. As a result, his designs remained theoretical blueprints, gathering dust in archives for decades.

Though he never saw his machines come to life, Babbage’s work profoundly influenced future generations. In the 20th century, his ideas were rediscovered and celebrated as the foundation of modern computing. Alan Turing, often considered the father of computer science, was heavily influenced by Babbage’s concept of a programmable machine.

In 1991, a team at the Science Museum in London built a working Difference Engine using Babbage’s original designs. The machine worked flawlessly, proving that his ideas were sound and that it was the limitations of his era that had held him back. So next time you boot up your computer or pull out the calculator on your phone, spare a thought for Charles Babbage. Without his temporally misplaced intellect, who knows how differently things could have turned out?

Plants convert only 1-2% of the sunlight they absorb into chemical energy, yet the total energy produced globally through photosynthesis is approximately 130 terawatts; that’s around 8 times more than current human energy consumption. This illustrates the enormous potential for harnessing even a fraction of sunlight to power renewable technologies, such as artificial photosynthesis, which could revolutionise the way we generate and use energy.

Nature’s process of converting sunlight, carbon dioxide and water into energy has long been a subject of interest for scientists, as it holds the potential to become a sustainable and carbon-neutral energy source. However, while progress has been made in laboratory settings, scaling up this technology to a level where it can replace conventional energy sources is still a significant challenge.

Artificial Photosynthesis Theory

The technology behind artificial photosynthesis operates in two main stages. The first involves light absorption, utilising photo-electrochemical (PEC) cells made with semiconductor materials like titanium dioxide. These cells imitate the role of chlorophyll in plants by capturing sunlight. In the second stage, the PEC cells convert the absorbed light into electrical energy. This energy is then used to split water molecules into hydrogen and oxygen while transforming carbon dioxide into hydrocarbons.

Artificial Photosynthesis Challenges

Significant challenges remain in enhancing the stability and efficiency of the materials used in photo-electrochemical (PEC) cells to capture more sunlight at a reduced cost. One of the primary limitations in this area has been the reliance on rare materials and the complexity of the systems required. Even more pressing, though, is the scalability of this technology to meet global energy demands. To convert sunlight into storable fuels efficiently, integration with existing energy infrastructure is essential – a complex task requiring substantial advancements in both technology and economic feasibility.

Progress In Artificial Photosynthesis

Progress in artificial photosynthesis has advanced rapidly, driven by breakthroughs in nanotechnology, materials science and artificial intelligence. Researchers at the University of Cambridge have, for example, developed an ‘artificial leaf’ that mimics natural photosynthesis, producing syngas – a sustainable liquid fuel alternative to petrol. Additionally, scientists at the Daegu Gyeongbuk Institute of Science and Technology in South Korea have made significant strides in solar hydrogen production using advanced photo-electrochemical (PEC) cells. The integration of artificial photosynthesis with other renewable technologies, such as solar panels, has also led to the development of hybrid systems capable of producing both hydrogen fuel and electricity.

While artificial photosynthesis is not yet commercially viable on a large scale, the progress achieved so far holds significant promise. As both governments and private sectors continue to invest in green technologies, it could soon play a pivotal role in addressing the world’s energy and environmental challenges.

One of nature’s most radiation-resistant microorganisms, Deinococcus radiodurans (pictured), can survive 5,000 times the amount of radiation that would kill a normal person. Methanogens, on the other hand, can survive entirely without oxygen. They are both known as extremophiles, mainly microbes, which thrive in the most unexpected and extreme environments, offering insights into the origins of life in conditions dominated by such hostile surroundings. Scientists study the remarkable mechanisms of these microbes with the aim of developing innovative technologies and materials.

What Are Extremophiles?

Extremophiles have developed specialised adaptations that enable them to survive in conditions typically considered inhospitable to life. Microaerophiles can survive with little to no oxygen, while halophiles can survive in high saline environments such as salt flats. Researchers have also found microbes from the Firmicutes phylum at least 13 feet below the Atacama desert that are able to survive in such conditions and could lead the way in the search for life on Mars.

Thermophiles can survive in hot environments exceeding 100C while psychrophiles prefer sub-zero temperatures. Thermus aquaticus, a bacterium that thrives in water above 70C was discovered at Yellowstone national park. Its enzymes were found to remain functional at extreme temperatures, a discovery that ultimately paved the way for the development of PCR-based COVID-19 tests nearly 50 years after they were first detected.

Mechanisms Of Survival

The remarkable adaptability of extremophiles begins at the cellular level, often driven by biochemical and structural adaptations. Some microbes can produce specialised enzymes and proteins while modifying their membrane composition to become more rigid or flexible, allowing them to survive extreme temperature fluctuations. Tightly folded protein structures, for example, are able to withstand high temperatures without denaturing while lipids and fatty acids can help make cell membranes rigid and heat resistant.

Enhanced DNA repair systems can help microorganisms withstand high radiation environments. Some extremophiles safeguard their DNA by utilising histone-like proteins to enhance its stability and employing highly efficient repair mechanisms to fix any damage.

Applications In Science And Industry

The unique abilities of extremophiles have made them invaluable in fields like medicine, biotechnology, industry, agriculture and space exploration. As we saw above, the enzyme Taq polymerase, derived from Thermus aquaticus, is used to amplify DNA in the Polymerase Chain Reaction (PCR) included in COVID-19 testing. Extremophiles are also crucial in bioremediation, where their ability to degrade toxic substances can aid in the cleaning up oil spills or soil contamination. Furthermore, studying how certain extremophiles endure high radiation and extreme vacuum conditions can aid in the development of technologies for long-term space exploration.

Microplastics are tiny pieces of plastic less than 5 millimetres in size. These fragments have permeated every corner of our planet, from the depths of the ocean to the peaks of mountains and even into our atmosphere. They are well known to cause issues to our environment and health, and now new research indicates that they are even able to influence our weather patterns.

Airbourne Microplastics

It is estimated that approximately 25 million metric tons of microplastics are transported through the atmosphere worldwide each year. These microscopic particles are primarily carried into the air by terrestrial winds from various surfaces, including land, oceans and urban areas. Human activities have also significantly contributed to the spread of microplastics. The incineration of waste, including plastics and synthetic materials, releases these particles into the atmosphere. Additionally, industrial emissions further contaminate the air on both local and global levels.

Impact On Climate Systems

Once in the atmosphere, microplastics can act as artificial cloud condensation nuclei, influencing cloud properties like their density and lifespan. This can lead to changes in rainfall patterns, affecting both intensity and frequency in certain areas. They may also interact with sunlight, either reflecting or absorbing its heat which can potentially disrupt localised weather systems. Additionally, their composition often includes toxic substances that can impact atmospheric chemistry.

One of the more intriguing potential effects of microplastics is their role in influencing atmospheric circulation. An increase in airborne microplastics could alter air density, affecting air movement, wind patterns and jet streams. These changes in atmospheric dynamics may disrupt thermal movements and precipitation patterns, potentially influencing weather events such as droughts and floods. The resulting shifts in weather systems could have significant impacts on natural ecosystems, affecting biodiversity and the health of habitats.

The Albedo Effect

In addition to influencing weather patterns, airborne microplastics may also contribute to global warming. The Albedo Effect refers to a surface’s ability to reflect sunlight, with surfaces like snow and ice having high albedo, helping to keep temperatures low by reflecting most of the sunlight that hits them. When microplastics settle on these surfaces, they reduce reflectivity, causing more sunlight to be absorbed, thereby raising the temperature. They can have a similar effect on the oceans. Not only can they raise water temperatures, but they may also impact its salinity. The combined effect of accelerated ice and snow melt, along with rising ocean temperatures, could significantly contribute to global warming.

Further Research

The study of microplastics and their effects on the atmosphere is still in its early stages, with research on the topic gaining more traction in the 2010s. While the full extent of their impact on the atmosphere remains unclear, researchers are using theoretical models to predict their potential future effects. These models aim to simulate how microplastics could influence weather patterns, air quality and global ecosystems in the coming decades.

Science is an ever-evolving field, and ideas once accepted as fact have often later been found to be incomplete or incorrect. As new evidence and advanced tools become available, scientists are able to refine, challenge, or even overturn earlier theories. In this article, I’ll explore five scientific theories that were once widely accepted but later disproved or replaced by more accurate models. Although I initially considered including the flat Earth theory, I’ve excluded it, as the belief that medieval scholars widely thought the Earth was flat is largely a myth. In fact, as early as the 5th century BC, the Ancient Greeks, and later European and Middle Eastern scholars in the early Middle Ages (600–1000 AD), had already recognised the Earth’s sphericity.

Spontaneous Generation

For much of history, people believed that life could spontaneously arise from non-living matter, a concept known as spontaneous generation. According to this theory, organisms like flies, fleas, and maggots could materialise from decaying meat. The work of great Thinkers such as Aristotle gave support to this idea for centuries. However, in the 17th century, the Italian physician Francesco Redi began to question it. Using a series of scientific experiments, he demonstrated that maggots only appeared on meat if flies had access to lay eggs there. In the 19th century, Louis Pasteur conducted further experiments, ultimately disproving spontaneous generation and paving the way for germ and cell theory, which eventually grew into the field of microbiology.

Geocentric Model Of The Solar System

Given our vantage point on Earth, it’s easy to see how people once believed we were at the centre of the solar system—or even the universe. Up until the 16th century, this geocentric model (with Earth at the centre) was widely accepted. It wasn’t until the investigations of Nicolaus Copernicus and later scientists that the heliocentric scientific model (with the Sun at the centre) gained acceptance in mainstream science, reshaping our understanding of the cosmos.

Miasma Theory Of Disease

Before modern medicine, people believed that diseases like cholera, plague, and malaria were caused by “miasma,” or “bad air” filled with noxious vapours from decaying matter. According to the miasma theory, simply breathing polluted air could make a person ill. This idea persisted for centuries until germ theory, supported by work from pioneers like Antony van Leeuwenhoek and Louis-Daniel Beauperthuy, established that disease is caused by microorganisms, not by foul air.

The Age Of The Earth

Today, we estimate that Earth is about 4.54 billion years old, a figure determined through radiometric dating of the oldest rocks on Earth and the Moon. This understanding is relatively recent. For centuries, based on biblical interpretations, people believed that Earth was only around 6,000 years old. This estimate aligned with religious texts but began to conflict with 19th-century scientific discoveries in archaeology, geology, and evolutionary biology, which pointed to a much older Earth.

Why The Dinosaurs Became Extinct

Surprisingly, until the 1980s, the leading scientific theory was that dinosaurs became extinct due to a massive super-volcano eruption. Other hypotheses suggested that dinosaurs were wiped out by a plague or died off due to an inability to adapt, possibly because of their small brains. I remember learning these now-outdated theories in school! About a decade later, however, scientists discovered the Chicxulub crater, providing evidence that a meteor strike 66 million years ago likely ended the age of dinosaurs.

In a previous article, I explored the powerful G-forces we experience on rollercoasters, which mimic the intense accelerations felt by Formula 1 drivers or astronauts. These forces create unmistakable sensations of disorientation and physical pressure.

Yet here we are, riding our very own galactic rollercoaster, planet Earth, which rotates at around 1,000 mph and orbits the Sun at 67,000 mph. Remarkably, we’re neither flung off into space by powerful centrifugal forces nor disoriented by Earth’s dizzying speeds. We don’t feel any sense of motion, G-forces, or even a breeze in our hair. So why is that?

Constant Speed, No Acceleration

Unlike the sudden, jolting accelerations we feel on a rollercoaster, Earth’s rotation and orbit are incredibly smooth and constant, with no sudden changes in speed. Because there’s no acceleration, there are no G-forces to register, and we feel nothing as a result. Putting G-forces aside for the moment, since we’re traveling at a mind-boggling 67,000 mph, shouldn’t we feel some sense of movement?

Absolute vs. Relative Motion

The concept of relative motion explains why we don’t feel the Earth’s speed. Everything on Earth’s surface, including the atmosphere, is moving with the planet at the same speed. This shared motion means there’s no relative difference to signal to our bodies that we’re moving. We feel stationary because we’re moving in perfect unison with our surroundings.

Stephanie Deppe, an astronomer at the Vera C. Rubin Observatory in Chile, likens this to riding in a car: “If you’re in a car going at a constant speed on the highway, if you close your eyes and tune out the road noise, you’d feel stationary. But if that car were braking repeatedly, you’d sense the motion. Because it maintains a constant speed, you feel motionless.”

Rotation And Gravity 

Finally, gravity plays a critical role. Earth’s rotation does create a centripetal acceleration (about 0.03 m/s²) that could, in theory, fling us outward. But gravity, at 9.8 m/s², is overwhelmingly stronger and holds us firmly to the ground. Gravity essentially “cancels out” the minor centrifugal effects we would otherwise feel.

In essence, Earth’s constant, smooth rotation and the overwhelming force of gravity make it impossible for us to feel the motion or G-forces of our planet’s high-speed journey through space.

Understanding the environment is paramount to protecting the planet, but with the overload of information available, some terminology can get lost along the way. ‘Biodiversity’, for instance, is a staple buzzword when it comes to climate change, but what does it really mean?

Biodiversity Defined

Quite simply, biodiversity means ‘the variety and abundance of the world’s plants and animals’ (Flora & Fauna, 2024). On a global scale, biodiversity might refer to an entire species at risk of extinction, while on a local scale, a rainforest is home to tens of thousand different species – this is a biodiverse environment. The rainforest is rich in biodiversity, whereas a plantation with only one type of tree would lack biodiversity, as it may not support many other species.

Biodiversity Loss

A reduction in the number of plant and animal species is known as biodiversity loss. The extinction of species worldwide is an indicator of biodiversity loss and currently, it’s declining faster than ever before – some scientists even believe the Earth is experiencing its sixth mass extinction. Species extinction is just one essential element of biodiversity loss, but it also results in deprivation of the services that natural ecosystems provide to humans, such as the oxygen we breathe or the pollination process.

What Causes Biodiversity Loss?

According to Earth.org, there are four key causes of biodiversity loss. While natural processes can result in permanent changes to the environment, human activity since the Industrial Revolution has expedited the loss. Habitat loss due to land and forest clearing is a significant driver. The human development of land and expanding industries has caused the loss of millions of hectares of trees and their associated ecosystems. This means that natural habitats, such as forests, are declining, having a catastrophic impact on the animals, plants and insects they are home to.

Wildlife trading causes nearly 30,000 species to become extinct every year. Wildlife and exotic pet trading, as well as animal poaching, often target vulnerable species putting them at greater risk of extinction. Overfishing means that due to the demands of the commercial fishing industry, humans fish at a higher rate than stocks are able to replenish. Despite the regulations in place, many marine species are in decline.

Climate change is perhaps most widely known as contributing to biodiversity loss and environmental damage, as the human dependence on fossil fuels and the consequent greenhouse gas emissions have caused climate change. The rising temperature across the globe means that species cannot move or adapt quickly enough to keep up with the changes, putting millions of species at risk of extinction.

Fundamentally, biodiversity is the planet’s superpower; the Earth’s capability to home so many living things.

The How Why And When Of The Northern Lights

Normally, spotting the Northern Lights from the UK would be a rare event, as these vivid auroras are usually reserved for higher latitudes. However, with the current solar maximum—when the sun’s activity peaks—more people in the UK are catching glimpses of this spectacular phenomenon from their back gardens or at least from a local hilltop. Stargazers across the country are now enjoying unexpectedly vibrant auroras lighting up our skies. However, even when we can see them with the naked eye, there is still much to them that remains hidden. Here are several things you may not have realised about the lights, and where they are most apparent.

The Camera Sees More Than You Do

While photos of the Northern Lights showcase vivid greens, purples, and even reds stretching across the sky, the view with the naked eye may not be quite as intense. Our eyes can capture the lights, but only cameras with long-exposure settings can truly bring out the full range of colors and details. In person, the Northern Lights might appear as softer hues or faint glows, especially in lower-latitude regions like the UK.

If you’re hoping for those stunning, vibrant displays, bring along a good camera. With the right settings, your camera can absorb light over a few seconds, producing images that reveal the richer, more intricate colors that the human eye alone can’t see. This simple trick transforms what might seem like a faint glow into the dazzling Northern Lights display captured in so many iconic images. For detailed tips on photographing the auroras, check out this article on EarthSky.org.

You Have to Put In the Effort To See Them Properly

Catching sight of the Northern Lights from the UK requires a bit of planning and patience. Unlike Scandinavian cities in the far north, like Reykjavik or Tromsø, where the auroras can sometimes be visible even in urban areas, seeing them here means avoiding light pollution and finding a truly dark spot. You’ll likely need to leave the city and head to more rural areas; national parks, remote beaches, or countryside vantage points offer the best chance of witnessing the lights.

The Best Time to Catch the Northern Lights Is After A New Moon

When trying to see the Northern Lights, moonlight can be surprisingly disruptive. A bright, full moon illuminates the sky and competes with the subtle glow of the auroras, making them harder to see, especially in areas further south, like the UK, where the lights are typically dimmer. That’s why nights following a new moon, when it is darkest or barely visible, provide the best opportunity. After a new moon, there’s minimal natural light in the sky, allowing even faint auroras to stand out more clearly against the darkness.

Which Direction To Look In To Best See Them

I have to admit I found conflicting information on this which rather confirms my point that they don’t tell you which direction to face! Aurorawatch at Lancaster University suggests that from the UK, north is the direction to look. However, when geomagnetic activity is very high and you are located in the north of the UK, then they suggest the Northern Lights may be south of you, and conclude you should check all directions. The Space Weather Prediction Centre seemed to suggest north too, however, so I think that’s the answer I am sticking with!

The Best Auroras Occur Around Midnight

A lesser-known fact revealed by the Space Weather Prediction Centre is that the Northern Lights are best viewed around midnight. While auroras may appear earlier in the evening or the morning, they are typically less active and visually appealing then.

Experiencing the Northern Lights is a unique and magical event, especially for those of us in the UK who don’t often have the chance to see them. By understanding the nuances, such as the importance of timing, location, and preparation, you can increase your chances of witnessing this awe-inspiring natural phenomenon.

When it comes to climate change, fine art and literature aren’t the first topics that spring to mind. In fact, STEM topics and the Humanities are often pitted against one another, or viewed as fundamentally conflicting. However, on the topic of climate change, we can learn a great deal from taking a more non-binary approach. The planet’s changing temperature has been empirically documented for centuries, and there’s no denying the importance of its accuracy and necessity, but recently, it has been noted that changes to the climate and increasingly polluted air were also long observed in the art of the past.

Pollution In Paintings

At the Huntington Library, Art Museum and Botanical Gardens, a new exhibition investigates how environmental and climate damage was perceived and represented by Western intellectuals in the years 1780 – 1930. It shows how the human impact on the environment was recognised much earlier than the past few decades, as we tend to understand it today. As well as John Constable’s View on the Stour Near Dedham (1822), and John Ruskin’s lecture in 1844 describing ‘the storm cloud, or more accurately, plague cloud’, the exhibition includes visual and literary artworks by the Romantics and Pre-Raphaelites, recognising how pollution was caused by the rapid industrialisation of the 19th century.

Blurring Boundaries

Demonstrating a historic view of the development of geology, glaciology, meteorology and ecology that emerged in this period, the exhibition highlights how women and art have contributed to science, which have been overlooked in past representations. With a blend of iconic art, literary and scientific works, the museum displays evidence of art’s integral role in science, and how art and science have, in fact, been intertwined throughout history.

Evidence Of Climate Change Origins In Artwork

Extraordinarily, we can see how works of art complement scientific findings which confirm the tragic impact of burning fossil fuels. The picturesque landscapes previously depicted by 18th century artists were challenged by the likes of Constable, who grappled with the effects of pollution in his artwork, by including hints of industrialisation in his scenic portrayals. Through artistic representations, it’s evident how the instigation of the climate crisis was perceived and reflected by key thinkers of the time, and we can even get a sensory glimpse of the newly polluted world.

What Can We Learn?

By reflecting on how these figures illuminated the climate crisis from its origin, and taking stock of what artistic and scientific evidence suggests, we can look to both vocations to embody findings about the environment today, and understand the human role in protecting and preserving the planet for years to come.
