Isaac Barrow (October 1630 – 4 May 1677) was an English Christian theologian, and mathematician who is generally given credit for his early role in the development of infinitesimal calculus; in particular, for the discovery of the fundamental theorem of calculus. His work centered on the properties of the tangent; Barrow was the first to calculate the tangents of the kappa curve. Isaac Newton was a student of Barrow's, and Newton went on to develop calculus in a modern form. The lunar crater Barrow is named after him.

Barrow was born in London. He was the son of Thomas Barrow, a linen draper by trade. Thomas married Ann, daughter of William Buggin of North Cray, Kent in 1624 and their son Isaac was born in 1630. Ann died in 1634 and Thomas sent Isaac to live with his grandfather. He went to school first at Charterhouse (where he was so turbulent and pugnacious that his father was heard to pray that if it pleased God to take any of his children he could best spare Isaac), and subsequently to Felsted School, where he settled and learned under the brilliant puritan Headmaster Martin Holbeach who ten years previously had educated John Wallis. Having learnt Greek, Hebrew, Latin and logic at Felsted, in preparation for university studies, he continued his education at Trinity College, Cambridge; his uncle and namesake, afterwards Bishop of St Asaph, was a Fellow of Peterhouse. He took to hard study, distinguishing himself in classics and mathematics; after taking his degree in 1648, he was elected to a fellowship in 1649. Barrow received an MA from Cambridge in 1652 as a student of James Duport; he then resided for a few years in college, and became candidate for the Greek Professorship at Cambridge, but in 1655 he was driven out by the persecution of the Independents. He spent the next four years travelling across France, Italy and even Constantinople, and after many adventures returned to England in 1659.

Isaac ( /ˈaɪzək/;Hebrew: יִצְחָק, Modern Yitsẖak Tiberian Yiṣḥāq, ISO 259-3 Yiçḥaq, "he will laugh"; Yiddish: יצחק, Yitskhok; Ancient Greek: Ἰσαάκ, Isaak; Latin: Isaac; Arabic: إسحاق‎ or Arabic: إسحٰق‎ʼIsḥāq) as described in the Hebrew Bible, was the only son Abraham had with his wife Sarah, and was the father of Jacob and Esau. Isaac was one of the three patriarchs of the Israelites. According to the Book of Genesis, Abraham was 100 years old when Isaac was born, and Sarah was beyond childbearing years.

Isaac was the only biblical patriarch whose name was not changed, and the only one who did not leave Canaan. Compared to those of Abraham and Jacob, Isaac's story relates fewer incidents of his life. He died when he was 180 years old, making him the longest-lived patriarch.

The anglicized name Isaac is a transliteration of the Hebrew term Yiṣḥāq which literally means "He laughs/will laugh."Ugaritic texts dating from the 13th century BCE refer to the benevolent smile of the Canaanite deity El. Genesis, however, ascribes the laughter to Isaac's parents, Abraham and Sarah, rather than El. According to the biblical narrative, Abraham fell on his face and laughed when Elohim imparted the news of their son's eventual birth. He laughed because Sarah was past the age of childbearing; both she and Abraham were advanced in age. Later, when Sarah overheard three messengers of the Lord renew the promise, she laughed inwardly for the same reason. Sarah denied laughing when Elohim questioned Abraham about it.

Sir Isaac Newton PRS MP (25 December 1642 – 20 March 1727 [NS: 4 January 1643 – 31 March 1727]) was an English physicist, mathematician, astronomer, natural philosopher, alchemist, and theologian, who has been "considered by many to be the greatest and most influential scientist who ever lived." His monograph Philosophiæ Naturalis Principia Mathematica, published in 1687, lays the foundations for most of classical mechanics. In this work, Newton described universal gravitation and the three laws of motion, which dominated the scientific view of the physical universe for the next three centuries. Newton showed that the motions of objects on Earth and of celestial bodies are governed by the same set of natural laws, by demonstrating the consistency between Kepler's laws of planetary motion and his theory of gravitation, thus removing the last doubts about heliocentrism and advancing the Scientific Revolution.

Isaac Backus (January 9, 1724 – November 20, 1806) was a leading Baptist preacher during the era of the American Revolution who campaigned against state-established churches in New England.

Born in the village of Yantic, near the town of Norwich, Connecticut, Backus was influenced by the Great Awakening and the works of Jonathan Edwards and George Whitefield. He was converted in 1741. For five years, he was a member of a Separatist Congregationalist church. In 1746, he became a preacher. He was ordained in 1748. Backus became a Baptist in 1751 when he became pastor of the Middleborough Baptist Church in Middleborough, Massachusetts.

In 1764, Isaac Backus joined John Brown, Nicholas Brown, William Ellery, Stephen Hopkins, the Reverend James Manning, the Reverend Ezra Stiles, the Reverend Samuel Stillman, the Reverend Morgan Edwards and several others as an original fellow or trustee for the chartering of the College in the English Colony of Rhode Island and Providence Plantations (the original name for Brown University), the first Baptist school of higher learning.[1]

David Eric "Dave" Grohl (born January 14, 1969) is an American rock musician, multi-instrumentalist, and singer-songwriter, who is the lead vocalist, guitarist, primary songwriter and founder of the Foo Fighters, prior to which he was the drummer in the grunge band Nirvana. He is also the drummer and co-founder of the rock supergroup Them Crooked Vultures. Grohl has additionally written all the music and performed all the instruments for his short-lived side projects Late! and Probot, as well as being involved with Queens of the Stone Age numerous times throughout the past decade. He has performed session work (as a drummer) for a variety of musicians, including Garbage, Killing Joke, Nine Inch Nails, The Prodigy, Slash, Juliette Lewis, Tenacious D, Tom Petty and the Heartbreakers, and Lemmy Kilmister.

As a child, Grohl's family relocated from Warren, Ohio, to Springfield, Virginia, a suburb of Washington, D.C. Three years later, when Grohl was six, his parents divorced, and Grohl grew up living with his mother.
