Denmark has a long tradition of scientific and technological invention and engagement, and has been involved internationally from the very start of the [[scientific revolution]]. In current times, Denmark is participating in many high-profile international science and technology projects, including [[CERN]], [[ITER]], [[ESA]], [[International Space Station|ISS]] and [[E-ELT]]. Denmark was ranked 10th in the [[Global Innovation Index]] in 2024, down from 6th in 2020 and from 7th in 2019.<ref>{{Cite book |author=[[World Intellectual Property Organization]] |year=2024 |title=Global Innovation Index 2024: Unlocking the Promise of Social Entrepreneurship |url=https://www.wipo.int/web-publications/global-innovation-index-2024/en/ |access-date=2024-10-06 |website=www.wipo.int |page=18 |publisher=World Intellectual Property Organization |language=en |doi=10.34667/tind.50062 |isbn=978-92-805-3681-2 |archive-date=10 December 2024 |archive-url=https://web.archive.org/web/20241210002031/https://www.wipo.int/web-publications/global-innovation-index-2024/en/ |url-status=live }}</ref><ref>{{Cite news |last=WIPO |title=Global Innovation Index 2022|edition=15th |url=https://www.wipo.int/global_innovation_index/en/2022/index.html |access-date=16 November 2022 |website=www.wipo.int |year=2022 |publisher=World Intellectual Property Organization |doi=10.34667/tind.46596 |isbn=9789280534320 |language=en |archive-date=3 December 2022 |archive-url=https://web.archive.org/web/20221203061259/https://www.wipo.int/global_innovation_index/en/2022/index.html |url-status=live }}</ref><ref>{{Cite web|title=Release of the Global Innovation Index 2020: Who Will Finance Innovation?|url=https://www.wipo.int/global_innovation_index/en/2020/index.html|access-date=2 September 2021|work=World Intellectual Property Organization|language=en|archive-date=3 June 2021|archive-url=https://web.archive.org/web/20210603121259/https://www.wipo.int/global_innovation_index/en/2020/index.html|url-status=live}}</ref><ref>{{Cite web|title=Global Innovation Index 2019|url=https://www.wipo.int/global_innovation_index/en/2019/index.html|access-date=2 September 2021|work=World Intellectual Property Organization|language=en|archive-date=2 September 2021|archive-url=https://web.archive.org/web/20210902101818/https://www.wipo.int/global_innovation_index/en/2019/index.html|url-status=live}}</ref>

In the 20th century, Danes have also been innovative in several fields of the technology sector. Danish companies have been influential in the shipping industry with the design of the largest and most energy efficient container ships in the world, the [[Maersk Triple E class]], and Danish engineers have contributed to the design of [[MAN Diesel]] engines. In the software and electronic field, Denmark contributed to design and manufacturing of [[Nordic Mobile Telephone]]s, and the now-defunct Danish company [[DanCall]] was among the first to develop [[GSM]] mobile phones.

[[Life science]] is a key sector with extensive research and development activities. Danish engineers are world-leading in providing [[diabetes]] care equipment and medication products from Novo Nordisk and, since 2000, the Danish [[biotech]] company [[Novozymes]], the world market leader in enzymes for first generation starch-based [[bioethanol]], has pioneered development of enzymes for converting waste to [[cellulosic ethanol]].<ref>{{cite web|url=http://www.canadianbiomassmagazine.ca/index.php?option=com_content&task=view&Itemid=132&id=3101|title=Novozymes, the world's leading provider of enzymes to the biofuels industry|work=Canadian Biomass Magazine|access-date=7 October 2014|archive-url=https://web.archive.org/web/20141010095027/http://www.canadianbiomassmagazine.ca/index.php?option=com_content&task=view&Itemid=132&id=3101|archive-date=10 October 2014|url-status=live}}</ref> ''[[Medicon Valley]]'', spanning the [[Øresund Region]] between Zealand and Sweden, is one of Europe's largest life science [[business cluster|clusters]].

Danish-born computer scientists and software engineers have taken leading roles in some of the world's programming languages: [[Anders Hejlsberg]] ([[Turbo Pascal]], [[Delphi (programming language)|Delphi]], [[C Sharp (programming language)|C#]]); [[Rasmus Lerdorf]] ([[PHP]]); [[Bjarne Stroustrup]] ([[C++]]); [[David Heinemeier Hansson]] ([[Ruby on Rails]]); [[Lars Bak (computer programmer)|Lars Bak]], a pioneer in virtual machines ([[V8 (JavaScript engine)|V8]], [[Java virtual machine|Java VM]], [[Dart (programming language)|Dart]]). Physicist [[Lene Vestergaard Hau]] is the first person to stop light, leading to advances in [[quantum computing]], [[nanoscale engineering]], and [[linear optics]].
