British contributions to inventions, technology and science. All parts of the UK contributed to these in a big way with England and Scotland best known for it.
Northern Ireland's is less well known, but we've contributed to:

As I said, some of the world's greatest minds were born, bred and lived in the United Kingdom of Great Britain and Northern Ireland!
Much to be proud of!
