[[File:CMS Higgs-event.jpg|thumb|One possible signature of a Higgs boson from a simulated [[proton]]–proton collision. It decays almost immediately into two jets of [[hadron]]s and two [[electron]]s, visible as lines.]]In the early 21st century, some concepts that originated in 20th century physics were proven. On 4 July 2012, physicists working at CERN's [[Large Hadron Collider]] announced that they had discovered a new subatomic particle greatly resembling the [[Higgs boson]],<ref name="nytimes.com">{{cite news |url=https://www.nytimes.com/2012/07/05/science/cern-physicists-may-have-discovered-higgs-boson-particle.html?pagewanted=3&_r=1&ref=science |work=The New York Times |first=Dennis |last=Overbye |title=Physicists Find Particle That Could Be the Higgs Boson |date=4 July 2012 |access-date=7 June 2021 |archive-date=7 June 2021 |archive-url=https://web.archive.org/web/20210607031642/https://www.nytimes.com/2012/07/05/science/cern-physicists-may-have-discovered-higgs-boson-particle.html?pagewanted=3&_r=1&ref=science |url-status=live }}</ref> confirmed as such by the following March.<ref>{{Cite web |last=O'Luanaigh |first=Cian |date=2013-03-14 |title=New results indicate that new particle is a Higgs boson |url=https://home.web.cern.ch/news/news/physics/new-results-indicate-new-particle-higgs-boson |url-status=live |archive-url=https://web.archive.org/web/20151020000722/http://home.web.cern.ch/about/updates/2013/03/new-results-indicate-new-particle-higgs-boson |archive-date=2015-10-20 |access-date=2024-05-25 |website=[[CERN]]|type=Press release}}</ref> [[Gravitational wave]]s were first [[First observation of gravitational waves|detected]] on 14 September 2015.<ref>{{cite journal |title=Einstein's gravitational waves found at last |journal=Nature News |url=http://www.nature.com/news/einstein-s-gravitational-waves-found-at-last-1.19361 |date=11 February 2016 |last1=Castelvecchi |first1=Davide |last2=Witze |first2=Alexandra |doi=10.1038/nature.2016.19361 |s2cid=182916902 |access-date=25 May 2016}}</ref>

[[Positive psychology]] is a branch of psychology founded in 1998 by [[Martin Seligman]] that is concerned with the study of happiness, mental well-being, and positive human functioning, and is a reaction to 20th century psychology's emphasis on mental illness and dysfunction.<ref>{{Cite web |last=Gibbon |first=Peter |title=Martin Seligman and the Rise of Positive Psychology |url=https://www.neh.gov/article/martin-seligman-and-rise-positive-psychology |access-date=2024-05-26 |website=The National Endowment for the Humanities}}</ref>
