Carlo Rubbia Knight Grand Cross (born on 31 March 1934) is an Italian particle physicist and inventor who shared the Nobel Prize in Physics in 1984 with Simon van der Meer for work leading to the discovery of the W and Z particles at CERN.

Carlo Rubbia studied at Scuola Normale in Pisa and graduated doing cosmic ray experiments at Pisa University in 1959. He then went to the United States where he spent about one and a half years at Columbia University performing experiments on the decay and the nuclear capture of muons. This was the first of a long series of experiments that Rubbia has performed in the field of weak interactions and which culminated in the Nobel Prize-winning work at CERN. He received his PhD in physics from Columbia in 1959.

In 1960 he moved back to Europe, attracted by the newly founded CERN, where he worked on experiments on the structure of weak interactions. CERN had just commissioned a new type of accelerator, the Intersecting Storage Rings, using counter-rotating beams of protons colliding against each other. Rubbia and his collaborators conducted experiments there, again studying the weak force. The main results in this field were the observation of the structure in the elastic scattering process and the first observation of the charmed baryons. These experiments were crucial in order to perfect the techniques needed later for the discovery of more exotic particles in a different type of particle collider.

Silvio Berlusconi (Italian pronunciation: [ˈsilvjo berluˈskoːni] ( listen); born 29 September 1936) is an Italian politician and media tycoon who served three times as Prime Minister of Italy from 1994 to 1995, 2001 to 2006 and 2008 to 2011. Berlusconi is also the controlling shareholder of Mediaset and owner of A.C. Milan. He is nicknamed Il Cavaliere (The Knight) for his knighthood to the Order of Merit for Labour, which he received in 1977.

Berlusconi is the longest-serving post-war Prime Minister of Italy, and third longest-serving since Italy's unification, after Benito Mussolini and Giovanni Giolitti, holding three separate terms. Technically, he has been sworn in four times because after a cabinet reshuffle, as happened with Berlusconi in 2005, the new ministry is sworn in and subjected to a vote of confidence. He is the leader of the People of Freedom political movement, a centre-right party he founded in 2009. From November 2009 to November 2011, he was the most senior leader of the G8 countries. In 2012, Forbes magazine ranked him as the 169th richest man in the world with a net worth of US$5.9 billion.

Giordano Bruno (1548 – February 17, 1600), (Latin: Iordanus Brunus Nolanus) born Filippo Bruno, was an Italian Dominican friar, philosopher, mathematician and astronomer. His cosmological theories went beyond the Copernican model in proposing that the Sun was essentially a star, and moreover, that the universe contained an infinite number of inhabited worlds populated by other intelligent beings. He was burned at the stake by civil authorities in 1600 after the Roman Inquisition found him guilty of heresy for his pantheism and turned him over to the state, which at that time considered heresy illegal. After his death he gained considerable fame, particularly among 19th- and early 20th-century commentators who, focusing on his astronomical beliefs, regarded him as a martyr for free thought and modern scientific ideas.

Some assessments suggest that Bruno's ideas about the universe played a smaller role in his trial than his pantheist beliefs, which differed from the interpretations and scope of God held by the Catholic Church. In addition to his cosmological writings, Bruno also wrote extensively on the art of memory, a loosely organized group of mnemonic techniques and principles. The work of Frances Yates, especially influential in anglophone scholarship, argues that Bruno was deeply influenced by the astronomy found in Arab astrology, Neoplatonism and Renaissance Hermeticism. Other recent studies of Bruno have focused on his qualitative approach to mathematics and his application of the spatial paradigms of geometry to language.

Mohammad Abdus Salam,NI, SPk (Urdu: محمد عبد السلام, pronounced English pronunciation: /əbd̪ʊs səlɑm/, (29 January 1926 – 21 November 1996) was a Pakistani theoretical physicist and Nobel laureate in Physics for his work on the electroweak unification of the electromagnetic and weak forces. Salam, Sheldon Glashow and Steven Weinberg shared the 1979 Nobel prize for this discovery. Salam holds the distinction of being the first Pakistani and the first Muslim Nobel Laureate to receive the prize in the sciences.

Salam was a science advisor to the Government of Pakistan from 1960 till 1974, a position from which he played a major and influential role in Pakistan's science infrastructure. Salam was responsible for not only major development and contribution in theoretical and particle physics, but as well as promoting scientific research at maximum level in his country. Salam was the founding director of Space and Upper Atmosphere Research Commission (SUPARCO), and responsible for the establishment of the Theoretical Physics Group (TPG) in Pakistan Atomic Energy Commission (PAEC). As Science Advisor, Salam played an integral role in Pakistan's development of peaceful use of nuclear energy, and directed the research on development of atomic bomb project of Pakistan in 1972; for this, he is viewed as the "scientific father" of this programme in the views of the scientists who researched under his scientific umbrella. In 1974, Salam left Pakistan in protest when Pakistan Parliament controversially passed a parliamentary bill declaring Ahmadiyya Muslim Community as Non-Muslims. Even after his death, Salam remained one of the most influential scientists in his country. In 1998, following the country's nuclear tests, the Government of Pakistan issued a commemorative stamp, as a part of "Scientists of Pakistan", to honour the services of Salam.
