Research in physics is continually progressing on a large number of fronts.

In condensed matter physics, an important unsolved theoretical problem is that of [[high-temperature superconductivity]].<ref name="Legg2006">{{cite journal |last1=Leggett |first1=A.

In particle physics, the first pieces of experimental evidence for physics beyond the Standard Model have begun to appear. Foremost among these are indications that [[neutrino]]s have non-zero [[mass]]. These experimental results appear to have solved the long-standing [[solar neutrino problem]], and the physics of massive neutrinos remains an area of active theoretical and experimental research. The Large Hadron Collider has already found the Higgs boson, but future research aims to prove or disprove the [[supersymmetry]], which extends the Standard Model of particle physics. Research on the nature of the major mysteries of dark matter and [[dark energy]] is also currently ongoing.<ref>{{cite journal |last1=Gibney |first1=E. |year=2015 |title=LHC 2.0: A new view of the Universe |journal=[[Nature (journal)|Nature]] |volume=519 |issue=7542 |pages=142–143 |doi=10.1038/519142a |bibcode=2015Natur.519..142G |pmid=25762263 |doi-access=free }}</ref>

Although much progress has been made in high-energy, [[quantum]], and astronomical physics, many everyday phenomena involving [[complex system|complexity]],<ref name="nrc1997v9p161">{{harvnb|National Research Council|Committee on Technology for Future Naval Forces|1997|p=161}}</ref> chaos,<ref name="kellert1993p32">{{harvnb|Kellert|1993|p=32}}</ref> or [[turbulence]]<ref name="eames-quoting-feynman">{{cite journal |last1=Eames |first1=I. |last2=Flor |first2=J.

Complex problems that seem like they could be solved by a clever application of dynamics and mechanics remain unsolved; examples include the formation of sandpiles, nodes in trickling water, the shape of water droplets, mechanisms of [[surface tension]] [[catastrophe theory|catastrophes]], and self-sorting in shaken heterogeneous collections.{{efn |See the work of [[Ilya Prigogine]], on 'systems far from equilibrium', and others.}}<ref>{{Cite book |author1=National Research Council |chapter=What happens far from equilibrium and why |chapter-url= https://www.nap.edu/read/11967/chapter/7 |title=Condensed-Matter and Materials Physics: the science of the world around us |year=2007 |pages=91–110 |doi=10.17226/11967 |isbn=978-0-309-10969-7 |url-status=live |archive-url= https://web.archive.org/web/20161104001321/https://www.nap.edu/read/11967/chapter/7 |archive-date=4 November 2016}}<br />– {{cite arXiv |last1=Jaeger |first1=Heinrich M. |last2=Liu |first2=Andrea J. |author2-link=Andrea Liu|year=2010 |title=Far-From-Equilibrium Physics: An Overview |class=cond-mat.soft |eprint=1009.4874}}</ref>

These complex phenomena have received growing attention since the 1970s for several reasons, including the availability of modern mathematical methods and computers, which enabled [[complex systems]] to be modeled in new ways. Complex physics has become part of increasingly interdisciplinary research, as exemplified by the study of turbulence in aerodynamics and the observation of [[pattern formation]] in biological systems. In the 1932 ''Annual Review of Fluid Mechanics'', [[Horace Lamb]] said:<ref name="goldstein1969">{{harvnb|Goldstein|1969}}</ref>
{{blockquote|I am an old man now, and when I die and go to heaven there are two matters on which I hope for enlightenment. One is quantum electrodynamics, and the other is the turbulent motion of fluids. And about the former I am rather optimistic.}}
