SOLIDWORKS as a Design System: Series Overview

An engineering-led overview of the SOLIDWORKS Design Approach series: treating CAD as a design system rather than a menu structure, and the eighteen-part pathway from first prin…

Biology as Manufacturing: Recombinant Proteins, Gene Editing and mRNA at Scale

Three milestones that turned living systems into a manufacturing platform, made the instructions programmable, and compressed the development timeline to months.

Chemical Engineering at Scale: Ammonia Synthesis and the Continuous Process Plant

Industrial ammonia synthesis resolved a direct conflict between thermodynamics and kinetics, and in doing so established catalysis, high pressure, recycle and continuous operati…

Compression Ignition: Otto, Diesel and Thermal Efficiency

Three milestones in which an engine was designed from a thermodynamic argument rather than developed from an existing machine, and immediately outperformed everything else.

Engineering Education: From Apprenticeship to Degree

Four milestones in the institutional answer to applied science: if engineering rests on theory, apprenticeship alone can no longer produce an engineer.

Flow Production Comes of Age: The Moving Assembly Line and Statistical Process Control

The moving line made work flow at a fixed cycle; the control chart made process variation intelligible. Together they define how physical goods have been made ever since.

Fluids and Comfort: Powered Flight, Sailing Hydrodynamics and Air Conditioning

Three milestones united by fluid mechanics: a machine that generates lift to fly, a rig that generates lift to outrun the wind, and a cycle that moves heat against its gradient.

Generation Without Fuel: Photovoltaics and the Modern Wind Turbine

Two milestones whose importance lies in decades of accumulated process improvement rather than in a breakthrough, and in what a zero marginal fuel cost does to a power system.

Heat into Work: The Gas Turbine and the Fission Reactor

Two technologies with a straightforward efficiency argument that says run hotter, and one shared constraint: both are limited by what the hot parts are made of, not by thermodyn…

History of Engineering: Complete Collection Index

Master index to a six-series reference collection covering the history of engineering from the first engineered cities to 2020, with every page listed by series and order.

History of Engineering: From the First Cities to the Age of Steam

A structured reference series covering fifty-eight engineering milestones from the first engineered cities to the Rainhill trials, organised by engineering problem rather than b…

History of Engineering: Milestones of the Modern Era 1845-1910

A structured reference series covering twenty-six engineering milestones between 1845 and 1910, organised by engineering problem rather than by date.

History of Engineering: Milestones of the Modern Era 1911-1969

A structured reference series covering thirty-five engineering milestones between 1911 and 1969, organised by engineering problem rather than by date.

History of Engineering: Milestones of the Modern Era 1970-2020

A structured reference series covering forty-one engineering milestones between 1970 and 2020, organised by engineering problem rather than by date.

Iron at Scale: Coke Smelting, Puddling and the Boring Mill

Four milestones in metallurgy and machine tools without which the steam engine would have remained a curiosity, one of them driven by an environmental crisis.

Machine Element Design and Selection: Series Overview

A fifteen-part mechanical design reference covering bearings, belt and chain drives, couplings, gearboxes, gears, motors, shafts, springs, bolted and welded joints, power screws…

Making Things Differently: Additive Manufacturing and Composite Primary Structure

Three milestones that broke the link between geometric complexity and cost, and then took three decades each to reach certified service.

Materials for a Harder Duty: Stainless Steel, Light Alloys and Synthetic Polymers

Five materials milestones that each removed a constraint designers had treated as fixed: corrosion, weight, fibre supply, glazing cost and the stiffness penalty of mass.

Materials That Built the Modern World: Steel, Plastics and Engineered Timber

How the Bessemer converter, the first synthetic polymers and engineered wood products replaced found material properties with specified, warranted ones.

Measurement and Method: Instruments, Mathematics and Experimental Science

Seven milestones in roughly a century, after which an engineer could calculate in advance what had previously only been learned by building.

Moving People and Goods: Transport Engineering 1845-1950

A structured reference series covering nineteen milestones in marine, road and rail engineering over the century in which transport became a question of running economically and…

Power to the Water: Screw Propulsion, Expansion Engines and Oil Firing

Four milestones in which marine propulsion moved from consuming most of the ship to leaving room for the cargo that paid for it.

Pressure, Speed and Escape: Jet Airliners, Supersonic Flight and Spaceflight

Four milestones from a two-second rocket flight to a lunar landing, and one fatigue failure that changed how every aircraft since has been certified.

Prime Movers: The Internal Combustion Engine and Diesel-Electric Traction

Spark ignition against compression ignition, why compression ratio governs efficiency, and how diesel-electric traction solved the transmission problem by deleting it.

Storing Energy: The Lithium-Ion Cell, Hybrid Traction and Grid-Scale Batteries

Three milestones that made stored electricity dense enough to move a vehicle, then fast enough and cheap enough to stabilise a grid.

The Age of Applied Science: How Engineering Learned to Use Science

A structured reference series tracing how engineering stopped learning only from experience and began deriving results from science, with electrical engineering as the paradigm …

The American System: Interchangeable Parts, Assembly Lines and the Sewing Machine

Interchangeable manufacture and the lockstitch sewing machine replaced skilled fitting with repeatable process, moving the engineering effort from the product to the system that…

The First Practical Motor Car: Benz and the Features That Stuck

Three milestones, and an unusually clean case of a first design getting the architecture right, plus a patent case worth knowing.

The Greek Contribution: Abstract Geometry, Mechanics and the First Machines

Six milestones including the single most consequential idea in the whole set: that there are general laws and that they can be known.

The Iron and Steel Ship: Cellular Hulls and the Great Eastern

Three milestones in which a ship stopped being a shaped assembly of timbers and became a designed structure with a calculated stress distribution.
