In physics, relativity is the principle that measurements of space and time depend on the reference frame of the observer, and there is no preferred reference frame, which means that two people who are moving at different velocities will measure different distances and durations between the same two events, and both measurements are correct, and neither is more correct than the other, and the correctness is not a matter of opinion but of physics: each observer is measuring from a valid position, and the position determines the measurement, and the determination is not bias but geometry, and geometry is not judgment but structure, and structure is what produces the difference between two honest people who look at the same thing and see different things and both are right in their own frame.

1925, London. Clara Hargreave was twenty and she worked in a button factory in Whitechapel, which means her job was to press small pieces of plastic into the shape of buttons using a machine that was powered by a steam engine in the basement and that heated her hands to a temperature that was uncomfortable but not dangerous, because dangerous was a category that applied to the men who operated the looms, not to the women who operated the presses, and the category distinction was not based on physiology but on economics: it was cheaper to replace a woman with burned hands than a man with burned hands, because there were always more women available, which is the structural logic of gender in industrial systems: women are employed in the positions that are designed to be replaceable, and the replaceability is built into the wage structure, which pays less because the workers are assumed to be temporary, and the temporariness is assumed because the workers are women, and the women are assumed to be temporary because they will marry and leave, and the leaving is assumed because the women's lives are structured around marriage, which is the economic arrangement that defines their position: they work until they marry and then they stop working and the stopping is assumed to be permanent, which means that their work experience is not counted in pension calculations, which means that their labor is extracted without long-term compensation, which is the structural violence of the gendered lifecycle, and Clara understood this at twenty not in theoretical terms but in the terms of her body: her hands were already beginning to show the early signs of the repetitive strain that would, in ten years, become chronic pain, and the pain would be hers and uncompensated, because the factory owed her nothing beyond the wage she was paid, and the wage was set by the assumption that her work was temporary, and the assumption was wrong but the wage was not adjusted, and the adjustment is the difference between justice and extraction, and extraction is what the system does when the workers cannot organize, which is what the women in the button factory could not do, because organizing requires time and energy and resources that temporary workers do not have, and temporariness is not a personal condition but a structural one, and the structure produces the condition, and the condition prevents the response, and the response is organization, and the absence of response is extraction, and the extraction is the story of Clara Hargreave's life at twenty, in 1925, in a button factory in Whitechapel, in a body that was already bearing the cost of a system that assumed her labor was temporary and priced it accordingly and did not adjust when the temporariness became permanency and the pain became chronic and the chronic became the condition of her old age, which was thirty years away and already present in the joints of her hands, which is how structural violence works: it is present in the body before it is visible in the world, stored in tissue and cartilage and nerve as accumulated micro-damage that will not be diagnosed until it is too late to treat, which is the particular form of violence that is committed by systems that externalize their costs onto the bodies of the workers, which is all industrial systems, because all industrial systems produce waste and the waste is not just material but biological, and the biological waste is the worn-out bodies of the people who operate the machines, and the waste is externalized because internalizing it would increase the cost of production, and increased cost reduces profit, and profit is the goal of the system, and the goal produces the externalization, and the externalization is the violence, and the violence is not intentional but it is structural, and the structure is what matters, because structure determines outcomes regardless of intention.

Clara met Edmund in March of 1925. Edmund was a junior doctor at the Whitechapel Infirmary, which meant he was twenty-eight and overworked and underpaid and committed to a practice of medicine that was equal parts science and compassion and exhaustion, which is the condition of every doctor who serves a poor community, because the need is always greater than the resources and the resources are always inadequate and the inadequacy is not an accident but a policy, and the policy is that poor communities receive less medical funding than rich communities, which is not written in any statute but is written in the budget allocations, which are the physical manifestation of political priority, and the priority is that wealthy neighborhoods are more politically influential than poor neighborhoods, and the influence produces the allocation, and the allocation produces the inequality, and the inequality is the structural violence of healthcare distribution, which is not dramatic but it is cumulative, and cumulative is how violence works at the system level: not a single act but a thousand small allocations that produce a large difference over time, and the large difference is the mortality gap between rich and poor neighborhoods, which in 1925 London was twenty years, which means that a person born in Whitechapel could expect to live twenty years less than a person born in Kensington, and the twenty years is not a natural difference but a political one, and the political is produced by the structural, and the structure is what determines life and death, and the determination is not intentional but it is real, and the real is the twenty-year gap, and the gap is the distance between the reference frames of the two neighborhoods, and the distance is measured in years and the years are lived and not lived, and the living is Clara's life and the not living is the life that a Kensington woman would have lived, and the difference is structure, and structure is not malice but it is violence, and the violence is real, and the real is the twenty-year gap, and the gap is the story of London in 1925.

Edmund was from a middle-class family in Hampstead, which meant that he had grown up in a neighborhood where the expected lifespan was twenty years longer than the neighborhood where he worked, and he had chosen to work in Whitechapel deliberately, which means his life was a movement from one reference frame to another, and the movement was voluntary, which is a privilege that Clara did not have, because Clara had been born in Whitechapel and her reference frame was determined by her birth, and Edmund had chosen his, and the choice is the difference between the middle-class and the working-class experience of structural violence: the middle class experiences it as a problem to be solved and the working class experiences it as the condition of life, and the experience is determined by the reference frame, and the frame is determined by the class, and the class is determined by the birth, and the birth is the starting position in the structure, and the structure determines the measurement, and the measurement is the experience, and the experience is the life, and the life is Clara's and Edmund's and they are different and both are correct in their frames.

They fell in love in the way that people fall in love when they are moving through different reference frames: with a sense of distance that is not emotional but structural, a gap that is not between their feelings but between their positions in the system, and the gap is real and it is measured in things that are not romantic: in the color of the walls in the houses they grew up in, in the food that was served at their family tables, in the way that their parents spoke about work and marriage and the future, and the way is the reference frame, and the frame produces the speech, and the speech produces the understanding, and the understanding is different, and the difference is not personal, it is structural, and the structure is what determines whether love can bridge the gap or whether the gap is too wide, and the width is not a measure of love but of structure, and structure is what matters, because structure determines outcomes, and the outcome of Clara and Edmund's love was determined not by their feelings but by the distance between their reference frames, and the distance was measured in years and money and social position and the weight of family expectation and the geometry of a city that was divided by class and the division was not physical but social and the social produced the physical: the neighborhoods were different because the investment was different, and the investment was different because the politics were different, and the politics were different because the influence was different, and the influence was different because the wealth was different, and the wealth was different because the wages were different, and the wages were different because the assumptions about temporariness were different, and the assumptions were different because the gender and class hierarchies were different, and the hierarchies were different because the structure was different, and the structure was what determined the outcome, and the outcome was not love or not love but the space between love and not love, which is the space that structural distance occupies, and the space is not emotional but geometric, and the geometry is not judgment but measurement, and the measurement is correct in each frame, and both frames are correct, and the correctness is the relativity of social position, which is the principle that two people can love each other and measure their distance differently and both measurements are right, because rightness is a function of position, and position is structure, and structure is what produces the difference between Clara's experience and Edmund's experience of the same love, and the difference is not a flaw in either of them but a feature of the system they inhabit, and the system is what matters, because the system determines the outcome, and the outcome is the story.

1975, London. Eleanor Hargreave was sixty and she was Clara's daughter, and she was living in the same neighborhood where Clara had worked in the button factory and which had changed in ways that were visible and ways that were not. The factory had closed in 1968, replaced by a retail store that sold clothing manufactured in Bangladesh, which is the global continuation of the same structural logic that had governed the button factory: extract labor from the workers who are most replaceable and pay them the least and assume their work is temporary and price it accordingly and externalize the costs onto their bodies, which is the pattern that has repeated across centuries and continents: industrial systems produce biological waste, and the waste is the worn-out bodies of the workers, and the waste is externalized because internalizing it would increase costs, and increased costs reduce profit, and profit is the goal, and the goal produces the externalization, and the externalization is the violence, and the violence is structural and cumulative and real, and the real is the body that bears the cost, and the body is Clara's in 1925 and the body is the Bangladeshi worker's in 1975 and the body is always someone's mother or daughter or sister, and the someone is the system, and the system is what matters, and the pattern is what repeats, and the repetition is not fate but structure, and the structure is the reference frame, and the frame determines the measurement, and the measurement is the life, and the life is always someone's daughter's, and the daughter is Eleanor in 1975 and she is Clara in 1925 and the two women are connected by blood and by structure, and the structure is the same and the measurement is different and both are correct in their frames, and the correctness is relativity, and relativity is the principle that there is no preferred frame, and the principle applies to social position as well as velocity, and the social reference frames of 1925 and 1975 are different, and the difference is measured in the changes that occurred between them: the factory closing and the retail store opening and the clothing moving from domestic to global production, and the movement is the continuation of the same logic in a different geography, and the geography is the structure, and the structure produces the measurement, and the measurement is the life, and the life is Eleanor's and Clara's and they are different and both are right in their frames, and the frames are 1925 and 1975 and the distance between them is fifty years and the distance is not progress but transformation, and the transformation is not improvement but change, and the change is structural, and the structure is what determines the measurement, and the measurement is the life, and the life is the story.

Eleanor lived in the flat above the retail store on Commercial Street. She was widowed, her husband Harold having died of lung cancer in 1972, which is the continuation of the biological waste production of industrial systems, now manifested not in the factory but in the smoking culture that had consumed Harold's generation, and the smoking was not forced on Harold but it was encouraged by a society that advertised tobacco to working-class men and subsidized the industry and normalized the behavior and externalized the cost onto the healthcare system, which is the same structural logic that had governed the button factory: extract value from the workers and externalize the cost onto their bodies and the system that serves them, and the system is the healthcare system and the body is Harold's and the cost is borne by the National Health Service, which was established in 1948, between the two reference frames, as a structural response to the violence of externalization, as an attempt to internalize the cost of healthcare and make it universal rather than differential, and the attempt was partially successful, because the NHS reduced the twenty-year mortality gap but did not eliminate it, which is the difference between reform and transformation: reform adjusts the structure but does not change it, and transformation requires changing the structure, and the structure is the profit system, and the profit system produces the externalization, and the externalization produces the biological waste, and the waste is Harold's body and Clara's hands and the Bangladeshi worker's lungs and the waste is the product of the structure and the structure is what matters, and the matter is the body, and the body is always someone's mother or daughter, and the daughter is Eleanor and the mother is Clara and the granddaughter is not born yet and the structure will continue and the externalization will continue and the waste will continue and the measurement will continue and the frames will change and the measurements will change and the correctness will remain, because correctness is relative to frame, and frame is structure, and structure is what repeats, and the repetition is not fate but physics, and the physics is relativity, and relativity is the principle that all frames are valid and no frame is preferred and the validity is the truth and the truth is that Clara was right in 1925 and Eleanor is right in 1975 and the distance between their truths is fifty years and the distance is not progress but the continuation of structural violence in a slightly different form, and the form is different and the violence is the same and the same is the structure and the structure is what determines the measurement and the measurement is the life and the life is the story and the story is told from two reference frames and both frames are correct and the correctness is relativity and relativity is the truth and the truth is structural and structure is what matters and what matters is the body and the body is always someone's mother or daughter and the daughter is Eleanor and the mother is Clara and the love that connected them to Edmund in 1925 and to no one in 1975 was the same love and different love and both were correct in their frames and the frames are 1925 and 1975 and the distance is fifty years and the distance is relativity and relativity is the principle and the principle is the story and the story is the lives of Clara and Eleanor and the lives are measured from different frames and both measurements are right and the rightness is relativity and relativity is the truth and the truth is that all frames are valid and no frame is preferred and the validity is the only truth there is, because truth is not absolute but relative, and relative is the word that describes the lives of women in a structural system that determines their measurements and their lives and their love and their loss and the loss is Harold and the hands and the lungs and the waste and the externalization and the profit and the structure and the frame and the measurement and the life and the story and the story is told from two frames and both are right and the rightness is relativity and relativity is the principle and the principle is the physics of social position and the position determines the measurement and the measurement is the life and the life is the story and the story is Clara and Eleanor and the frames are 1925 and 1975 and the distance is fifty years and the distance is not progress but transformation and the transformation is not improvement but change and the change is structural and the structure is the reference frame and the frame is the measurement and the measurement is the life and the life is the story and the story is relative and relativity is the truth and the truth is structural and structure is what matters and what matters is always the body and the body is always someone's mother or daughter and the daughter is Eleanor and the mother is Clara and the love was real in both frames and the reality is the measurement and the measurement is correct in each frame and the correctness is relativity and relativity is the principle and the principle is the story.
