England (which included Wales at the time) and Scotland were leading centres of the Scientific Revolution from the 17th century.[2] The United Kingdom led the Industrial Revolution from the 18th century,[3] and has continued to produce scientists and engineers credited with important advances.[4] Some of the major theories, discoveries and applications advanced by people from the United Kingdom are given below.
First tunnel under a navigable river, first all iron ship and first railway to run express services, contributed to by Isambard Kingdom Brunel (1806–59).[14]
The United Kingdom plays a leading part in the aerospace industry, with companies including Rolls-Royce playing a leading role in the aero-engine market; BAE Systems acting as Britain's largest and the Pentagon's sixth largest defence supplier, and large companies including GKN acting as major suppliers to the Airbus project.[36] Two British-based companies, GlaxoSmithKline and AstraZeneca, ranked in the top five pharmaceutical companies in the world by sales in 2009[37] and UK companies have discovered and developed more leading medicines than any other country apart from the US.[38] The UK remains a leading centre of automotive design and production, particularly of engines, and has around 2,600 component manufacturers.[39] Investment by venture capital firms in UK technology companies was $9.7 billion from 2010 to 2015.[40]
The UK is one of only 3 nations with $1 trillion technology industry.[citation needed]
Scientific research and development remains important in British universities, with many establishing science parks to facilitate production and co-operation with industry.[41] Between 2004 and 2012, the United Kingdom produced 6% of the world's scientific research papers and had an 8% share of scientific citations, the third- and second-highest in the world (after the United States' 9% and China's 7% respectively).[42][43] Scientific journals produced in the UK include Nature, the British Medical Journal and The Lancet.
Britain was one of the largest recipients of research funding from the European Union. From 2007 to 2013, the UK received €8.8 billion out of a total of €107 billion expenditure on research, development and innovation in EU Member States, associated and third countries. At the time, this represented the fourth largest share in the EU.[44] The European Research Council granted 79 projects funding in the UK in 2017, more than any other EU country.[45][46] The United Kingdom was ranked 5th in the Global Innovation Index in 2024.[47]

^Alexander Graham Bell, born and raised in Scotland, made a number of inventions as a British citizen, notably the telephone in 1876; he did not become an American citizen until 1882, and then spent the remaining years of his life predominately living in Canada at a summer residence.
^In the early 1960s, Paul Baran invented distributed adaptive message block switching for digital communication of voice messages using switches that were low-cost electronics. His work did not include routers with software switches and communication protocols, nor the idea that users, rather than the network itself, would provide the reliability.[29][30][31]

Paul Baran ... focused on the routing procedures and on the survivability of distributed communication systems in a hostile environment, but did not concentrate on the need for resource sharing in its form as we now understand it; indeed, the concept of a software switch was not present in his work.
^Pelkey, James L. "6.1 The Communications Subnet: BBN 1969". Entrepreneurial Capitalism and Innovation: A History of Computer Communications 1968–1988. As Kahn recalls: ... Paul Baran's contributions ... I also think Paul was motivated almost entirely by voice considerations. If you look at what he wrote, he was talking about switches that were low-cost electronics. The idea of putting powerful computers in these locations hadn't quite occurred to him as being cost effective. So the idea of computer switches was missing. The whole notion of protocols didn't exist at that time. And the idea of computer-to-computer communications was really a secondary concern.
