Problem: Mary (mother of Jesus):

Despite Martin Luther's harsh polemics against his Roman Catholic opponents over issues concerning Mary and the saints, theologians appear to agree that Luther adhered to the Marian decrees of the ecumenical councils and dogmas of the church. He held fast to the belief that Mary was a perpetual virgin and the Theotokos or Mother of God. Special attention is given to the assertion that Luther, some three-hundred years before the dogmatization of the Immaculate Conception by Pope Pius IX in 1854, was a firm adherent of that view. Others maintain that Luther in later years changed his position on the Immaculate Conception, which, at that time was undefined in the Church, maintaining however the sinlessness of Mary throughout her life. For Luther, early in his life, the Assumption of Mary was an understood fact, although he later stated that the Bible did not say anything about it and stopped celebrating its feast. Important to him was the belief that Mary and the saints do live on after death. "Throughout his career as a priest-professor-reformer, Luther preached, taught, and argued about the veneration of Mary with a verbosity that ranged from childlike piety to sophisticated polemics. His views are intimately linked to his Christocentric theology and its consequences for liturgy and piety." Luther, while revering Mary, came to criticize the "Papists" for blurring the line, between high admiration of the grace of God wherever it is seen in a human being, and religious service given to another creature. He considered the Roman Catholic practice of celebrating saints' days and making intercessory requests addressed especially to Mary and other departed saints to be idolatry. His final thoughts on Marian devotion and veneration are preserved in a sermon preached at Wittenberg only a month before his death:

Problem: Muammar Gaddafi:

International reactions to Gaddafi's death were divided. U.S. President Barack Obama stated that it meant that "the shadow of tyranny over Libya has been lifted," while UK Prime Minister David Cameron stated that he was "proud" of his country's role in overthrowing "this brutal dictator". Contrastingly, former Cuban President Fidel Castro commented that in defying the rebels, Gaddafi would "enter history as one of the great figures of the Arab nations", while Venezuelan President Hugo Chávez described him as "a great fighter, a revolutionary and a martyr." Nelson Mandela expressed sadness at the news, praising Gaddafi for his anti-apartheid stance, remarking that he backed the African National Congress during "the darkest moments of our struggle". Gaddafi was mourned by many as a hero across Sub-Saharan Africa, for instance, a vigil was held by Muslims in Sierra Leone. The Daily Times of Nigeria stated that while undeniably a dictator, Gaddafi was the most benevolent in a region that only knew dictatorship, and that he was "a great man that looked out for his people and made them the envy of all of Africa." The Nigerian newspaper Leadership reported that while many Libyans and Africans would mourn Gaddafi, this would be ignored by western media and that as such it would take 50 years before historians decided whether he was "martyr or villain."

Problem: Presbyterianism:

Presbyterianism first officially arrived in Colonial America in 1703 with the establishment of the first Presbytery in Philadelphia. In time, the presbytery would be joined by two more to form a synod (1717) and would eventually evolve into the Presbyterian Church in the United States of America in 1789. The nation's largest Presbyterian denomination, the Presbyterian Church (U.S.A.) – PC (USA) – can trace their heritage back to the original PCUSA, as can the Presbyterian Church in America (PCA), the Orthodox Presbyterian Church (OPC), the Bible Presbyterian Church (BPC), the Cumberland Presbyterian Church (CPC), the Cumberland Presbyterian Church in America the Evangelical Presbyterian Church (EPC) and the Evangelical Covenant Order of Presbyterians (ECO).

Problem: Glass:

The term mainly refers to a mix of lithium and aluminosilicates that yields an array of materials with interesting thermomechanical properties. The most commercially important of these have the distinction of being impervious to thermal shock. Thus, glass-ceramics have become extremely useful for countertop cooking. The negative thermal expansion coefficient (CTE) of the crystalline ceramic phase can be balanced with the positive CTE of the glassy phase. At a certain point (~70% crystalline) the glass-ceramic has a net CTE near zero. This type of glass-ceramic exhibits excellent mechanical properties and can sustain repeated and quick temperature changes up to 1000 °C.

How high of a temperature change can CTEs handle?
