Noor Muhammad Butt

3 June 1936), SI, FPAS, also known as N. M. Butt, is a Pakistani nuclear physicist and professor of physics at the Preston University who is known for his research publications in understanding the gamma-rays burst, Mössbauer effect, diffraction, later the nanotechnology.

: 17 [7] In 1965, Butt successfully defended his doctoral thesis and was conferred with the PhD in nuclear physics under the supervision of Philip Burton Moon from the Birmingham University in England.

: 3 [4] In 1961, Butt secured employment in the Pakistan Atomic Energy Commission (PAEC) as a scientific officer, and worked on the problems involved in reactor physics before departing to England for his doctoral studies.

: 2–3 [4] His career is mostly spent at the Institute of Nuclear Science and Technology, the country national laboratory site in Nilore, where he was instrumental in conducting scientific investigations in solid-state materials using the lattice dynamical settings and powder diffraction techniques.

[11] In 1999, Butt eventually left the Institute of Nuclear Science and Technology when he retired as first "Scientist Emeritus", and subsequently returned to academia to teach courses on physics.

[12] Collaboration between Butt and O'Connor established the scientific confirmation of Ivar Waller's Theory of Phonons at the Bragg diffraction peaks using the Mössbauer spectroscopy from LiF's single crystals.

: 8–9 [4] After his retirement from PAEC in 2000, Butt begin public advocacy for the benefits of the nanotechnology and engaged in providing education when he was appointed Chairman of National Commission on Nano-Science and Technology (NCNST) in 2003 and led till 2005.

: 27 [14] In 2010 interview with the news media, Butt also vehemently dismissed the American concerns about his nation's atomic weapons fall into the hands of terrorists as "farce claim" noting that they would be unable to select sequence targets to launch the missiles since they don't have required scientific education to understand the locking and triggering mechanism to activate nuclear devices.
