Physicist scientist who does research in physics

A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of physical phenomena and the analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies.

Theoretical physics branch of physics

Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain and predict natural phenomena. This is in contrast to experimental physics, which uses experimental tools to probe these phenomena.

Stockholm University state university of Stockholm, Sweden

Stockholm University is a public university in Stockholm, Sweden, founded as a college in 1878, with university status since 1960. Stockholm University has two scientific fields: the natural sciences and the humanities/social sciences. With over 34,000 students at four different faculties: law, humanities, social sciences, and natural sciences, it is one of the largest universities in Scandinavia. The institution is regarded as one of the top 100 universities in the world by the Academic Ranking of World Universities (ARWU).


Hansson received a PhD in 1979 at University of Gothenburg with a doctorate in Elementary particle (quarks). His recent research has been theoretical aspects of condensed matter physics.

Doctorate academic or professional degree

A doctorate or doctor's degree or doctoral degree is an academic degree awarded by universities that is, in most countries, a research degree that qualifies the holder to teach at the university level in the degree's field, or to work in a specific profession. There are a variety of doctoral degrees, with the most common being the Doctor of Philosophy (PhD), which is awarded in many different fields, ranging from the humanities to the scientific disciplines.

Elementary particle quantum particle having no known substructure; quark, electron, photon, etc.

In particle physics, an elementary particle or fundamental particle is a subatomic particle with no sub structure, thus not composed of other particles. Particles currently thought to be elementary include the fundamental fermions, which generally are "matter particles" and "antimatter particles", as well as the fundamental bosons, which generally are "force particles" that mediate interactions among fermions. A particle containing two or more elementary particles is a composite particle.

He is active in the popularization of physics and science by including lectures, articles in newspapers and in Folkvett.

Hansson was elected as a member of the Royal Swedish Academy of Sciences in 2009. [3] He became director of Nordita in early 2016. [1]

The Royal Swedish Academy of Sciences or Kungliga Vetenskapsakademien is one of the royal academies of Sweden. It is an independent, non-governmental scientific organisation which takes special responsibility for the natural sciences and mathematics, but endeavours to promote the exchange of ideas between various disciplines.

In 2016, on the occasion of the announcement of the 2016 Nobel Prize in Physics, Hansson gave the committee's public explanation of the prize. His use of a cinnamon bun, a bagel, and a pretzel (to explain relevant topological ideas) was featured in many news reports of the announcement. [4] [5]

Nobel Prize in Physics One of the five Nobel Prizes established in 1895 by Alfred Nobel

The Nobel Prize in Physics is a yearly award given by the Royal Swedish Academy of Sciences for those who have made the most outstanding contributions for humankind in the field of physics. It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895 and awarded since 1901; the others being the Nobel Prize in Chemistry, Nobel Prize in Literature, Nobel Peace Prize, and Nobel Prize in Physiology or Medicine.

Topology Branch of mathematics

In mathematics, topology is concerned with the properties of space that are preserved under continuous deformations, such as stretching, twisting, crumpling and bending, but not tearing or gluing.

Aage Bohr Danish physicist

Aage Niels Bohr was a Danish nuclear physicist who shared the Nobel Prize in Physics in 1975 with Ben Mottelson and James Rainwater "for the discovery of the connection between collective motion and particle motion in atomic nuclei and the development of the theory of the structure of the atomic nucleus based on this connection". Starting from Rainwater's concept of an irregular-shaped liquid drop model of the nucleus, Bohr and Mottelson developed a detailed theory that was in close agreement with experiments. Since his father, Niels Bohr, had won the prize in 1922, he and his father were one of the six pairs of fathers and sons who have both won the Nobel Prize and one of the four pairs who have both won the Nobel Prize in Physics.

Felix Bloch Swiss physicist

Felix Bloch was a Swiss-American physicist and Nobel physics laureate who worked mainly in the U.S. He and Edward Mills Purcell were awarded the 1952 Nobel Prize for Physics for "their development of new ways and methods for nuclear magnetic precision measurements."
