A Sunlight Soap, produced by the Lever Brothers in the late 19th century, was a groundbreaking innovation in the world of consumer goods. At a time when hygiene and cleanliness were not universally prioritised, Sunlight Soap not only introduced a revolutionary product but also played a crucial role in transforming industrial production, marketing strategies and public health. The success of Sunlight Soap laid the foundation for what would later become Unilever, one of the world's largest multinational corporations. B The story of Sunlight Soap begins in 1884, when William Hesketh Lever and his brother James Darcy Lever established the Lever Brothers company in England. They sought to create a high-quality soap that was both affordable and effective in promoting hygiene. Traditional soaps at the time were often harsh on the skin and required extensive preparation. The Lever Brothers aimed to change this by producing a soap that was easy to use and gentle while maintaining strong cleansing properties. The innovation behind Sunlight Soap lay in its production process. Unlike the traditional method of soap-making, which relied on animal fats and wood ash, Sunlight Soap was manufactured using a blend of vegetable oils and alkali, resulting in a more consistent and superior-quality product. This not only improved the soap's effectiveness but also made it a more ethical and sustainable option compared with its contemporaries. C Beyond the product itself, the Lever Brothers were pioneers in marketing and branding. They understood the power of advertising and created memorable, persuasive campaigns for Sunlight Soap. These advertisements emphasised the soap's purity, its ability to fight germs, and its role in maintaining a happy and healthy home. The company used a variety of media, from newspapers and magazines to colourful posters and collectable cards, to reach a wide audience. This aggressive and innovative marketing strategy helped create a strong brand identity and fostered customer loyalty. D The company also revolutionised industrial relations and worker welfare. In 1888, Lever Brothers built a purpose-built factory and village called Port Sunlight on the Wirral Peninsula. This model village was designed to provide high-quality housing, amenities, and social benefits for its employees. It featured gardens, schools, a hospital, and recreational facilities, which were considered revolutionary for the time. This approach was part of William Lever's philosophy of "prosperity sharing," where he believed that a healthy and content workforce would lead to greater productivity and company success. Port Sunlight became a landmark in industrial planning and set a new standard for employee welfare. E The impact of Sunlight Soap on public health was significant. By promoting the importance of cleanliness with an effective and accessible product, it contributed to improved hygiene practices among the general public. This was particularly important in an era before the widespread understanding of germ theory. The widespread use of soap like Sunlight played a role in reducing the incidence of infectious diseases, thereby improving overall public health standards in Britain and beyond. F The phenomenal success of Sunlight Soap provided the capital and brand recognition for the Lever Brothers to expand their operations globally. They began acquiring other soap and food companies, steadily growing their portfolio. This expansion culminated in 1930 with a merger with the Dutch margarine company, Margarine Unie. This merger formed Unilever, a dual-headed company structure that remains unique to this day. The creation of Unilever marked the beginning of a new era, transforming a single soap product into a global consumer goods empire.

A Biophilic design, a movement related to green architecture, has gained much momentum within the building community in recent years. The premise of biophilic design is to avoid or minimise harmful impacts on the natural environment and, equally importantly, to provide and restore beneficial contacts between people and nature in the built environment. B People have a psychologically developed need to commune with nature, but this has frequently been neglected. All too often, architects put creative originality before the needs of the people who must live and work in their futuristic constructions, with scant regard for emotional as well as practical considerations. Biophilic design does not advocate tree houses or cave-dwelling, but it does provide nature-based features that maximise human functioning and health. Though not technically a biophilic design, Fallingwater—the stunning house in rural Pennsylvania designed in the 1930s by Frank Lloyd Wright—arguably speaks to the human soul far more than the box-like blocks of flats designed by his contemporary Le Corbusier. C In the modern world, much of our built environment obstructs the age-old connection between humans and nature. The rate of technological progress far exceeds the rate of psychological evolution, leaving us ill-equipped to cope with our lifestyles, which in turn leads to increased stress. Because biophilia attempts to integrate basic and current needs, it can alleviate the difficulties caused by the brain’s constant efforts to function in a modern environment it has not yet evolved to handle. For example, one crucial element of the natural landscape for human health is sunlight. We are evolutionarily programmed to respond positively to sunny areas over dark or overcast ones and sense that they will foster restoration, improve emotional well-being and promote health. D Because of its tremendous impact on human psychology, biophilic design plays a vital role in healthcare and its delivery. The current healthcare system contains many flaws, especially in its physical spaces. Hospitals, clinics and offices are high-stress environments for patients, visitors and healthcare professionals alike. One well-known study looked at the impact of nature on patients after surgery. One group had a view of a tree; the others had a window looking onto a brick wall. The first group had shorter hospital stays, received fewer negative comments from nurses, required fewer analgesics and had slightly fewer post-operative complications. E As a consequence of this and other studies, nature and nature-based design have been integrated into the physical design of many hospitals. For example, Dartmouth-Hitchcock Medical Center (DHMC) in New Hampshire boasts an atrium design illuminating the entire facility. Natural elements also permeate the building, including wood, stone and numerous live plants. While DHMC was built to incorporate these qualities, other hospitals have had biophilic features added to existing structures. The application of biophilic concepts to hospital interiors has increased substantially as administrators have witnessed patients’ positive responses to nature. F Many existing buildings contain biophilic elements, but only a few have been built with the specific idea of biophilic design in mind. One such building is the Adam Joseph Lewis Center for Environmental Studies at Oberlin College in Ohio. The director of Oberlin’s Environmental Studies Program, David Orr, explained that the building’s goals were “to create not just a place for classes but rather a building that would help to redefine the relationship between humankind and the environment—one that would expand our sense of ecological possibilities”. The Lewis Center is sustainable in a broader sense than in the typical application of the word. It harnesses solar power, utilises both active and passive air systems, and monitors the weather to adapt to conditions. The Centre’s “Living Machine” treats wastewater by combining traditional wastewater technology with wetland ecosystems’ purification processes, producing water that can be used in the toilets and for irrigation. In their design, Orr and his team of architects engineered a healthy and comfortable space for students while ensuring the surrounding environment was undamaged. G Another example is the University of Guelph-Humber building in Ontario, Canada. It contains a centrally located bio-wall, vertically spanning the building. The wall is covered in dense foliage which not only connects people to nature on the inside of the building, but also functions as a new filtration-system prototype. The wall purifies the air and has the potential to fulfil the building’s fresh-air-intake requirements. These examples prove that the built environment need not interfere with biological human needs to commune with nature, nor with existing ecological systems. H Ancient architects built for their cultures, which were almost always more in touch with the earth than Western society is today. They mimicked nature’s forms, producing magnificent structures that still awe us—though biophilic design is a novel concept, they certainly employed some of its recommendations. Today we can add another layer to this tradition and ensure maximal benefit for our planet and ourselves.

Maps codify the miracle of existence. And the man who wrote the codes for the maps we use today was Gerard Mercator, a cobbler’s son born 500 years ago on a muddy floodplain in northern Europe. Mercator was a humble man with a universal vision. In his own time he was ‘the prince of modern geographers’, his depictions of the planet and its regions unsurpassed in accuracy, clarity and consistency. More recently, he was crowned by the American scholar Robert W. Karrow as ‘the first modern, scientific cartographer’. Where his predecessors had adopted a piecemeal approach to cartography, Mercator sought to wrap the world in systematic overlapping maps. Along the way he erected a number of historic milestones. He participated in the naming and mapping of ‘America’, he constructed the two most important globes of the 16th century, and the title of his pioneering ‘modern geography’, the Atlas, became the standard term for a volume of maps. Mercator also devised a new method - ‘a projection’ - of converting the spherical world into a two-dimensional map. Mercator was born in 1512 and died in 1594. His world was one of military conflict, social upheaval, religious revolution - and geographical discovery. He was ten years old when the survivors of the world’s first circumnavigation returned to Spain in their leaking caravel. No better example is required of genius arising from turmoil. He knew poverty, plague, war and persecution. He was imprisoned for his ideas yet patronised by an emperor. His life was one of brilliant breakthroughs and abrupt reversals. In its telling, his is the story of the poor boy made good: the pauper who embraced the world, found fame, faced death, yet triumphed through fortitude. Variously described by his peers as honest, calm, candid, sincere and peaceable, Mercator wore an aura of calm in troubled times. His attitude to his geographical calling was described by his friend and neighbour, William Ghim, as ‘indefatigable’. Some 40 or so of Mercator’s letters have survived, together with examples of virtually all of his printed maps and globes. Mercator’s most significant work was a project of cosmic proportions. A multi-part cosmography, the work would include a section on astronomy, a chronology of world events and a modern geography, which would eventually contain over 100 maps. Before he commenced the great work, Mercator produced in 1569 an enormous world map on a new projection. His method for converting the spherical globe into a two-dimensional map helped to solve the greatest cartographic riddle of the day: how could the course of a ship following a constant compass bearing be represented as a straight line on a map which had been constructed on a grid of latitude and longitude? Mercator’s solution was to progressively increase the space between his lines of latitude, away from the equator. The effect was to straighten the lines of constant compass bearing (also known as rhumbs or loxodromes). Unfortunately, straightening the rhumbs caused areal distortion: at the map’s northern and southern extremities, the polar regions occupied the full width of the map, while North America appeared to fill half the circumference of the world. Few of Mercator’s contemporaries understood what he was up to, despite the map’s title explaining that it was intended ‘for use in navigation’. Mercator knew that his projection was unsuitable as an areal description of the world, but it would be several decades before the map’s true navigational value would be recognised. Meanwhile, Mercator was marshalling and editing all the geographical data he needed for his modern regional maps of the world. His sources were wide-ranging and multitudinous, including an imperial physician in Vienna and his competitor, the Viceroy of Holstein. He was still working on these maps when he died. The great cosmography that Mercator had already titled ‘Atlas’ would never be finished. In the Atlas, Mercator had embodied the principles of future mapmaking: his italic lettering, his identical map overlaps, his complete coverage of regions at more than one scale, his consistent use of grids of latitude and longitude, his singular editorial control, were all adopted as cartographic standards. ‘Atlas’, the cosmography, became ‘atlas’, the (Oxford English Dictionary) term for ‘a collection of maps in a volume.’ The projection assumed a life of its own. So powerful a cartographic tool did it become that Mercator the man became subsumed by his own device. By the 20th century, Mercator’s Projection had been adopted by state cartographers to map the land that he had named ‘North America’. In 1938, Mercator’s Projection was selected by the Ordnance Survey to map Britain anew. And in 1974, the American cartographer Alden P. Colvocoresses used the Space Oblique Mercator Projection for the first satellite map of the USA. When the Jet Propulsion Laboratory sent Mariner 8 and Mariner 9 to map Mars, they undertook their Martian cartography on a standard Mercator Projection. One by one, the mappable orbs of our solar system are appearing on the worldwide web, flattened for our screens according to Mercator’s cartographic principles. Mercator’s Projection succeeded in reconciling the sphere and the plane, while his Atlas enveloped the world with an integrated system of maps.
