Regulators and fundamental units of real quadratic fields, the continued fraction algorithm, the exponential cost problem, and Shanks's infrastructure with the distance function.
Two machines that move in opposite directions and solve the same problem: making ground and height usable without disturbing what is already there.
Three milestones in which electricity moved into railway traction, and in which the alternating-versus-direct argument was fought again under different constraints.
Three milestones within two years, none of which invented a device. Each fixed an interface or made a hidden structure explicit, and each generated more value than most inventio…
Australian metropolitan desalination turned urban water supply from a hydrological problem into an energy and membrane one, and produced an asset with an unusual duty profile.
Four milestones showing what changed in civil engineering once dynamic behaviour could be analysed properly and construction method became the primary design driver.
Three projects, three constraints, one lesson: at civil scale the hard engineering is in measurement, power distribution and load path, not in the visible structure.
Four milestones in moving goods overland, and a reminder that for bulk freight before the railway, water beat road every time.
Four milestones in which urban water and waste became one system, and in which the profession learned that a treatment barrier can appear to succeed for sixty years.
Three milestones between 1854 and 1860 established the modern urban water system: treat what comes in, separate and treat what goes out, and store enough head to survive a failure.
Engineering begins as a response to water. Four milestones in levees, canals, urban drainage and bringing supply inside the walls.
Three milestones showing what happens when concrete construction moves from large to unprecedented, and the governing parameter turns out to be hydrology, creep or heat rather t…
