The Templeton Prize was established in 1972 by Sir John Templeton for exceptional contribution to affirming the spiritual dimension of life, and Mother Teresa, the founder of the Missionaries of Charity in Kolkata, received the very first award in 1973; she went on to win the Nobel Peace Prize in…

Balkrishna Vithaldas Doshi became the first Indian to win the Pritzker Prize when it was conferred on him in 2018; he had trained under Le Corbusier, and his works include the Indian Institute of Management at Bangalore and the Aranya low-cost housing at Indore.

The Pritzker Architecture Prize was founded in 1979 by Jay A. Pritzker and Cindy Pritzker through the Hyatt Foundation of the United States, and the first laureate in that year was Philip Johnson of the United States.

This is the complement law for addition, which corresponds to the OR operation. Whatever value A takes, one of A and its complement must be 1, and an OR gate gives 1 whenever any input is 1, so the expression is 1 in both cases.

Each input can take one of two values, so for three inputs the number of distinct combinations is two multiplied by itself three times, that is two raised to the power three, which is eight.

It is the only gate that takes a single input, and it simply reverses the logic level it receives, giving 1 for an input of 0 and 0 for an input of 1; because the output is the inverse or complement of the input, the circuit is called an inverter.

Adding two single bits gives a sum that is 1 when exactly one of the bits is 1 and 0 when both are 0 or both are 1, which is precisely the XOR rule; so in a half adder the sum line comes from an XOR gate.

The system was a work of pure mathematics for decades until Claude Shannon showed that it described electrical switching circuits exactly, which opened the way to digital computing.

In Boolean algebra a literal is any single appearance of a variable in an expression, whether it appears plain or with a bar over it.

An exclusive OR gate is a difference detector: it gives 1 for the combinations 0 and 1 or 1 and 0, and gives 0 when the inputs agree.

De Morgan's second theorem states that NOT of A AND B equals NOT A OR NOT B. The working rule is to break the bar and change the sign, so a dot under a complement becomes a plus once the complement is distributed over the variables.

Each of these gates alone is enough to build every other gate and so every logic circuit: a NAND with its two inputs tied together acts as a NOT, two NANDs in sequence give an AND, and a suitable arrangement of three gives an OR, and the same can be…

Read the table row by row. The output is 0 only when both inputs are 0, and it is 1 in the other three rows, including the row where both inputs are 1.

OPEC was founded in 1960 at a conference in Baghdad by Iran, Iraq, Kuwait, Saudi Arabia and Venezuela, and its secretariat was first at Geneva before moving to Vienna in 1965, where it remains.

The South Asian Association for Regional Cooperation was founded in 1985 at Dhaka, where its charter was signed, and its permanent secretariat was set up at Kathmandu in Nepal in 1987.

The United Nations Monetary and Financial Conference met at Bretton Woods in New Hampshire in the United States in July 1944 and agreed to set up the International Monetary Fund and the International Bank for Reconstruction and Development, which is why the two are called the Bretton Woods twins; both…

The WTO began on 1 January 1995 as the outcome of the Uruguay Round, and it replaced the General Agreement on Tariffs and Trade as a permanent organisation with a dispute settlement system.

The OECD was established in 1961 as the successor of the Organisation for European Economic Co-operation, which had been created to administer aid under the Marshall Plan, and it works from Paris as a forum of mostly high-income countries that sets standards and publishes comparative statistics.

The New Development Bank was agreed at the sixth BRICS summit at Fortaleza in Brazil in 2014 and began work with its headquarters at Shanghai, with K. V. Kamath of India as its first president and an African regional centre in South Africa.

South Africa was invited to join in 2010 and took part in the summit at Sanya in China in 2011, and the letter S was added to the acronym to make BRICS.
