Welsh Inventions

Wales is one of the four constituent countries that make up the United Kingdom. It is located to the west of England, covering an area of 20,779 square kilometres and has a population of approximately 3.1 million people. The capital and largest city is Cardiff, which serves as the political, cultural, and economic centre of the country.

Wales became formally integrated into the Kingdom of England, and later the United Kingdom, through legislative acts in the 16th century. The Laws in Wales Act 1535, passed under King Henry VIII, annexed Wales to England, abolishing its separate legal system and creating a unified legal and administrative framework. This process was further solidified by the Laws in Wales Act 1542.

The Acts of Union 1707 united England—as well as Wales—with Scotland, forming the Kingdom of Great Britain. The Acts of Union 1800 later united Great Britain with Ireland, creating the United Kingdom of Great Britain and Ireland. After the partition of Ireland in 1922, the currently-existing United Kingdom of Great Britain and Northern Ireland was established.

Despite being somewhat overshadowed, Wales does have a rich history of achievements in culture, industry, science, and sports. For instance, it is known for its literature, music, and the Eisteddfod festival. Industrially speaking, Wales played a pivotal role in the Industrial Revolution, particularly in coal mining and steel production.

When it comes to the field of science, Wales has contributed a long list of significant inventions that impacted many areas of science and helped shape the world we live in now. In the next sections, we are going to explore 12 of those striking Welsh inventions.

1. The Equals Sign

Our very first Welsh invention is the equal sign (=), which was introduced by Welsh mathematician Robert Recorde in his book “The Whetstone of Witte,” published in 1557. Recorde used parallel lines to indicate equality, stating that “to avoide the tediouss repetition of these woordes: is equalle to: I will sette as I doe often in woorke use, a paire of paralleles, or gemowe lines of one lengthe.”

This innovation simplified mathematical expressions and laid the foundation for modern algebraic notation.

2. The Pi Symbol

The pi symbol is one of the important mathematical symbols that originated from Welsh mathematicians. It symbolises the constant, which is the ratio of a circle’s circumference to its diameter, which is approximately 3.14159.

The concept of pi has been used for thousands of years in various mathematical calculations and formulae. Welsh mathematician William Jones first introduced the symbol for pi in 1706, but it was later popularised by another Welsh mathematician named William Oughtred.

Today, the pi symbol is widely recognised and used in mathematics, science, engineering, and other fields. 

3. Ball Bearings

The very first model of ball bearings was invented by Philip Vaughan, a Welsh inventor and ironmaster, in Carmarthen, Wales, in 1794.

Vaughan’s design used multiple steel balls to reduce friction between moving parts in machinery, allowing for smoother and more efficient operation. This invention revolutionised various industries, particularly manufacturing and transportation, by improving the performance and durability of machinery such as steam engines and railway locomotives.

Vaughan’s contribution laid the groundwork for the development and widespread use of ball bearings in modern machinery.

4. The Hydrogen Fuel Cell

A hydrogen fuel cell is basically a device that transforms the chemical energy from hydrogen into clean electricity through an electrochemical reaction with, yes, oxygen. It operates similarly to a battery but can continuously produce electricity as long as fuel (hydrogen) is supplied. This invention has the potential to revolutionise transportation by powering cars, buses, and even aeroplanes with clean energy and eliminating reliance on fossil fuels.

The invention of hydrogen fuel cell is credited to Sir William Robert Grove, a Welsh lawyer and physicist, who in 1839 developed the first crude fuel cell known as the “gas battery.” Grove demonstrated that it was possible to generate electricity by combining hydrogen and oxygen in the presence of an electrolyte.

Afterwards, precisely in the 1930s and 1940s, British engineer Francis Thomas Bacon developed more practical and efficient alkaline fuel cells, leading to significant advancements in fuel cell technology. His work laid the foundation for the fuel cells used in the Apollo space missions.

5. The Microphone

The invention of the microphone is attributed to several key figures who contributed to its development in the late 19th century, with the most widely recognised inventors in this context being Emile Berliner and Thomas Edison.

That said, Sir William Preece, a prominent Welsh electrical engineer and inventor, played a significant role in the development and popularisation of the microphone. These contributions are primarily associated with his role in recognising, refining, and implementing David Edward Hughes’ carbon microphone technology in the British telephone system.

Consequently, Preece helped enhance the quality of telecommunication during the late 19th century.

6. Ophthalmic Surgery

Welsh contributions to ophthalmic surgery, though less renowned than those from other regions, involve notable figures and institutions in medicine and surgery.

Prominent ophthalmologist Sir Thomas Pemberton Herring, for instance, made substantial strides in diagnosing and treating eye diseases, while Welsh medical institutions like Cardiff University’s School of Optometry and Vision Sciences have played vital roles in research and education.

Additionally, Welsh medical professionals have spearheaded innovations in healthcare practices, influencing both ophthalmology and broader medical fields, with contributions extending to the NHS and global collaborations, reflecting the collaborative spirit inherent in medical progress.

7. Legalising Cremation

The legalisation of cremation in Wales marks a significant milestone in funeral customs, offering an alternative to traditional burials and expanding choices for individuals and families coping with loss.

Cremation, recognised for its environmental benefits in reducing land usage and conserving natural resources, grants flexibility for scattering ashes in meaningful locations or preserving them as keepsakes.

This legislative shift mirrors evolving societal perspectives on death, offering comfort to those desiring personalised farewell ceremonies. Welsh inventors have contributed not only to technology but also to advancements in cultural practices like funeral rituals, making a lasting impact on our society.

8. Early Flying Machines

Welsh inventors have also made significant contributions to the development of early flying machines.

One notable inventor, Sir George Cayley, is known as the “Father of Aeronautics” for his vital contributions to aviation that laid the foundation for modern flight. He figured out how objects could fly by studying the way air moves around them, known as aerodynamics.

Cayley also came up with the idea of fixed-wing aircraft, which is the basic design for aeroplanes today, with wings for lift and a separate part for propulsion and control.

Cayley did not just theorise; he also tested his ideas with actual models and gliders. In fact, one of his gliders, flown by his coachman in 1853, is one of the earliest recorded manned flights. Cayley’s emphasis on scientific experimentation and his innovative designs influenced later aviators, including the Wright brothers, who achieved powered flight in the early 20th century.

9. Radar

Like most inventions, radar, which stands for “Radio Detection and Ranging,” was not invented by a single individual but rather through the collaborative efforts of scientists and engineers across different countries over several decades.

The theoretical groundwork for radar technology was laid down in the late 19th and early 20th centuries by scientists such as Heinrich Hertz, who demonstrated the existence of radio waves, and Nikola Tesla, who experimented with radio wave transmission and reception. In the early 20th century, researchers like Christian Hülsmeyer and Sir Henry Tizard conducted experiments that laid the foundation for practical radar systems.

During World War II, Welsh physicist Joan Curran made a significant contribution to radar technology. Alongside her husband, Samuel Curran, she developed a radar countermeasure known as “Window” or “Chaff.” This involved dropping strips of aluminium foil from aircraft to confuse enemy radar systems, making it harder for them to detect Allied planes, which was a crucial advantage during air operations in the war.

10. Rigid Inflatable Boat (RIB)

The Rigid Inflatable Boat (RIB) is a type of watercraft characterised by a solid hull and inflatable tubes (sponsons) around the perimeter. These boats are versatile and widely used for various purposes, including military, commercial, and recreational applications.

Sir William Robert Barnett, a Welsh inventor and entrepreneur, significantly advanced Rigid Inflatable Boats (RIBs), contributing to their widespread adoption across various maritime applications. Credited with inventing the Avon Searider in the late 1960s, Barnett’s innovative design and propulsion advancements quickly propelled RIBs into commercial success.

As the founder of Avon Inflatables Ltd., Barnett also played a crucial role in commercialising RIBs, establishing Avon as a leading manufacturer and supplier to military, commercial, and recreational markets worldwide. His tireless promotion of RIBs for military and commercial use, coupled with his lasting impact on maritime technology and safety, solidifies Barnett’s legacy as a key figure in revolutionising watercraft design and application.

11. Packet Switching

Packet switching is a networking method that divides data into smaller packets for efficient transmission. These packets, each containing part of the original data and destination information, travel independently across the network. Once at their destination, they are reassembled into the original data. Such an approach optimises network resources by allowing multiple packets to be sent simultaneously and taking varied routes through the network.

Donald Davies, a Welsh computer scientist, revolutionised communication networks by developing the concept of packet switching in the late 1960s. He envisioned a decentralised network where data is broken into packets for transmission, coining the term “packet switching.”

Davies implemented this innovative idea in the NPL Data Communications Network, demonstrating its efficiency and robustness. His advocacy for packet switching influenced the development of the ARPANET, laying the groundwork for the modern internet‘s decentralised architecture and dynamic communication capabilities.

12. Josephson Effect

The Josephson effect is an important discovery in the field of physics. It was named after Brian David Josephson, a Welsh physicist who made this breakthrough in 1962. The effect describes how an electric current can flow in between two superconductors separated by a thin insulating barrier without any voltage applied.

This phenomenon is attributed to a quantum mechanical tunnelling effect and has significant applications in various fields. For example, it has been used in the development of highly accurate devices called superconducting quantum interference devices (SQUIDs), which are used for detecting tiny magnetic fields and currents.

The Josephson effect has also contributed to advancements in electronics and computing technology by enabling the creation of high-speed digital circuits known as Josephson junctions.
