How a bun, a bagel and a pretzel explain the 2016 Nobel Prize for Physics



“Look deep into nature and you will understand everything better.”



This quote from Albert Einstein could easily have served as a guiding principle for David Thouless, Duncan Haldane and Michael Kosterlitz.

The trio of British-born scientists has been awarded the Nobel Prize for Physics for their discoveries about strange or unusual forms of matter or, in the words of the Nobel Committee, “for theoretical discoveries of topological phase transitions and topological phases of matter.”

Here, in the simplest terms possible, is the Euronews who, what, why, where and when of Tuesday’s 2016 Nobel Prize for Physics.



Who





The three scientists are all British-born but now live and work in the United States.


David Thouless

  • Born in 1934 near Glasgow
  • Emeritus professor at the University of Washington

Duncan Haldane

  • Born in 1951 in London
  • Professor of physics at Princeton University

Michael Kosterlitz

  • Born in 1942 in Aberdeen
  • Affiliated to Brown University




What



Here comes the science.

The trio’s research looks at what is known as “Topology” – describing properties that change state in a stepwise manner.

It plays a significant part in the area of quantum physics.





More specifically:

Length, width and height are the three dimensions of matter that we are all familiar with.

However, in their theoretical research, Kosterlitz and Thouless focused on flat or two-dimensional forms of matter, for example on flat surfaces or extremely thin layers.

Haldane also studied one-dimensional matter, or extremely thin threads.

They came up with a mathematical model to explain the physical changes in rare states of matter like superconductors and superfluids, under these conditions.


Bagel, bun and pretzel


Monday’s 2016 Nobel Prize for Medicine began with experiments with baker’s yeast.

Tuesday’s Physics prize continues with the baking metaphor.

Thors Hans Hansson from the Nobel physics committee used a bagel, a pretzel and a cinnamon bun to explain the theory of topology.

The bun has no holes, the bagel has one hole and the pretzel has two.

Topology – what the scientists modeled – examines the unchanging properties of materials. For example, the number of holes in a pretzel remains the same whatever shape it is bent into.




Why



“This has paved the way for designing new materials with novel properties and there is great hope that this will be important for many future technologies,” – Acting chairman of the Nobel Committee, Professor Nils Mårtensson.

The discoveries have helped scientists design new materials for new technologies.



When



The three academics have worked on the concept throughout their lengthy careers.



The Nobel in Numbers



  • 110 – Nobel prizes in Physics awarded 1901-2016
  • 47 – Individual winners of Physics prize
  • 2 – Women awarded the Physics prize so far
  • 1 – person (John Bardeen) awarded the prize twice
  • 25 – age of youngest winner, Lawrence Bragg in 1915
  • 55 average age of the laureates
