That is a tough question. A really tough question! Am I only allowed one?
OK I will choose the transistor. Oh dear – here I go being boring again 🙂
Everything about our world depends on the transistor – a tiny bit of material so small you can now make thousands of them (millions of them) fit on a chip the size of fingernail.
Computers, phones, satellites, space travel, TV, medical monitors and scanners … I could go on all night. The one invention that makes them all possible is the transistor.
I won’t spoil it for you by giving you the history of the transistor – have a look at wikipedia!
I think I am going to be boring and list a theory not a device. The double-blind randomised placebo controlled clinical trial. This is the ONLY way to tell whether a medical treatment works or not and has revolutionised medicine more than any X-ray machine or MRI scanner. It has saved countless lives and prevented many toxic drugs getting on the market. Until its invention (late 19th century) doctors in ALL countries killed more people than they cured. Now it is the opposite.
And the greatest exponent of evidence-based medicine. Florence Nightingale. For some reason she is remembered as a lady with a lamp being nice to patients. in fact she was a gifted mathematician who analysed her hospital scientifically and revolutionised hospital services. But because she was a woman she is portrayed as just a “touchy feely” nurse rather than the great scientist she really was.
Nice answer Chris. And while we are on the subject – of women who are forgotten as good scientists – I would also like to mention Beatrix Potter! Famous for writing childrens stories but a cracking mycologist (expert in fungi).
Not exactly related to the question but just a random bit of information!

Yes – lots of good women in science. But just us two beardy men left in this zone …….
