Thouless, the other half jointly to F. Duncan M. Haldane and J. Michael Kosterlitz ”for theoretical discoveries of topological phase transitions and topological phases of matter”. Nobel in Physics 2016: Thouless, Kosterlitz and Haldane The Nobel winners have used advanced mathematical methods to explain strange phenomena in unusual phases (or states) of matter, such as superconductors, superfluids or thin magnetic films. Kosterlitz (Brown Univ) and Thouless (Washington Univ) have studied phenomena that arise in a flat world on surfaces or inside extremely thin layers that can be considered two-dimensional. Haldane (Princeton Univ) has also studied matter that forms threads so thin they can be considered one-dimensional. Bosons and fermions Any particle has an intrinsic angular momentum, called spin S~ = (Sx , Sy , Sz ), characterized by two quantum numbers s ed ms , where for s fixed one has ms = −s, −s +1, ..., s − 1, s, and in addition Sz = ms ~ , with ~ (1.054 · 10−34 Joule×seconds) the reduced Planck constant.

  • Nobel Laureates with Their Contribution in Biomedical Engineering
    NOBEL LAUREATES WITH THEIR CONTRIBUTION IN BIOMEDICAL ENGINEERING Nobel Prizes and Biomedical Engineering In the year 1901 Wilhelm Conrad Röntgen received Nobel Prize in recognition of the extraordinary services he has rendered by the discovery of the remarkable rays subsequently named after him. Röntgen is considered the father of diagnostic radiology, the medical specialty which uses imaging to diagnose disease. He was the first scientist to observe and record X-rays, first finding them on November 8, 1895. Radiography was the first medical imaging technology. He had been fiddling with a set of cathode ray instruments and was surprised to find a flickering image cast by his instruments separated from them by some W. C. Röntgenn distance. He knew that the image he saw was not being cast by the cathode rays (now known as beams of electrons) as they could not penetrate air for any significant distance. After some considerable investigation, he named the new rays "X" to indicate they were unknown. In the year 1903 Niels Ryberg Finsen received Nobel Prize in recognition of his contribution to the treatment of diseases, especially lupus vulgaris, with concentrated light radiation, whereby he has opened a new avenue for medical science. In beautiful but simple experiments Finsen demonstrated that the most refractive rays (he suggested as the “chemical rays”) from the sun or from an electric arc may have a stimulating effect on the tissues. If the irradiation is too strong, however, it may give rise to tissue damage, but this may to some extent be prevented by pigmentation of the skin as in the negro or in those much exposed to Niels Ryberg Finsen the sun.
