Biscaynes were produced primarily for the fleet market, though they were also available to the general public — particularly to those who wanted low-cost, no-frills transportation with the convenience, room and power of a full-size automobile. While most Biscaynes were sold with a six-cylinder engine through the late 1960s, the V8 engine became the more popular powerplant by the early 1970s.1. Power steering and power brakes were made standard in 1970, while the TurboHydramatic transmission was standard on all cars ordered with a V8 engine starting midway through the 1971 model year.
Like the slightly upscale Bel Air, Biscaynes were easily identified by the use of two taillights per side; the only exceptions to this were in 1959 and 1972. The more expensive Impala (and later Caprice) had three taillights per side. The Biscayne was largely devoid of exterior chrome trim and was normally fitted with small hubcaps, though several exterior trim pieces and upgraded wheel covers were available at extra cost. Interior trim was spartan, with lower-grade cloth and vinyl or all-vinyl upholstery trim, a standard steering wheel with center horn button, and rubber floor mats. Slight upgrades were made throughout the life of the series — for instance, the 1964 models came standard with deluxe steering wheel with horn ring, deep-twist carpeting and foam-cushioned front seats.
Many of the luxury convenience options available on the more expensive full-sized Chevrolet models, such as power windows, were not available on the Biscayne. However, customers could purchase a Biscayne with any of Chevrolet's high-output big-block V8 engines and performance-oriented transmissions, including the floor-mounted 4-speed manual transmission with Hurst shifter and low-ratio final drive. Original production numbers of cars built this way were very low, and examples of these high-performance cars are highly sought after by collectors today. Notably, Baldwin Chevrolet of Long Island, New York, became famous for offering the "Street Racer Special," a 1968 Biscayne coupe with dealer-fitted high-performance 427 cubic-inch V8, and heavy-duty suspension components, turning the Biscayne into a serious drag car. Biscaynes with high-performance equipment were often nicknamed "Bisquick" by enthusiasts.
However, the absence of most exterior and fancy interior trimmings remained through the life of the series, as the slightly costlier Chevrolet Bel Air offered more interior and exterior trimmings at a price still significantly lower than the mid-line Chevrolet Impala.
A number of economy-minded options were available exclusive to the Fleetmaster model, although the performance-oriented engines and transmissions were also available (for police applications or performance-oriented customers who wanted the lightest car possible). The Fleetmaster was dropped after 1961.

Sir Isaac Newton PRS (4 January 1643 – 31 March 1727 ) at Woolsthorpe Manor in Woolsthorpe-by-Colsterworth, a hamlet in the county of Lincolnshire. At the time of Newton's birth, England had not adopted the Gregorian calendar and therefore his date of birth was recorded as Christmas Day, 25 December 1642. Newton was born three months after the death of his father, a prosperous farmer also named Isaac Newton. Born prematurely, he was a small child; his mother Hannah Ayscough reportedly said that he could have fit inside a quart mug (≈ 1.1 litres). When Newton was three, his mother remarried and went to live with her new husband, the Reverend Barnabus Smith, leaving her son in the care of his maternal grandmother, Margery Ayscough. The young Isaac disliked his stepfather and held some enmity towards his mother for marrying him, as revealed by this entry in a list of sins committed up to the age of 19: "Threatening my father and mother Smith to burn them and the house over them." involved solving the problem of a suitable mirror material and shaping technique. Newton ground his own mirrors out of a custom composition of highly reflective speculum metal, using Newton's rings to judge the quality of the optics for his telescopes. In late 1668 Newton's reawakening interest in astronomical matters received further stimulus by the appearance of a comet in the winter of 1680-1681, on which he corresponded with John Flamsteed.
Towards the end of his life, Newton took up residence at Cranbury Park, near Winchester with his niece and her husband, until his death in 1727. and was buried in Westminster Abbey. His half-niece, Catherine Barton Conduitt, God said "Let Newton be" and all was light.
Newton himself had been rather more modest of his own achievements, famously writing in a letter to Robert Hooke in February 1676:
If I have seen further it is by standing on the shoulders of giants.
From 1978 until 1988, an image of Newton designed by Harry Ecclestone appeared on Series D £1 banknotes issued by the Bank of England (the last £1 notes to be issued by the Bank of England). Newton was shown on the reverse of the notes holding a book and accompanied by a telescope, a prism and a map of the Solar System. Snobelen concludes that Newton was at least a Socinian sympathiser (he owned and had thoroughly read at least eight Socinian books), possibly an Arian and almost certainly an antitrinitarian. In an age notable for its religious intolerance, there are few public expressions of Newton's radical views, most notably his refusal to take holy orders and his refusal, on his death bed, to take the sacrament when it was offered to him.
In a view disputed by Snobelen, T.C. Pfizenmaier argues that Newton held the Arian view of the Trinity rather than the Western one held by Roman Catholics, Anglicans, and most Protestants. Newton put him on trial a second time with conclusive evidence. Chaloner was convicted of high treason and hanged, drawn and quartered on 23 March 1699 at Tyburn gallows.
The famous three laws of motion (stated in modernised form): Newton's First Law (also known as the Law of Inertia) states that an object at rest tends to stay at rest and that an object in uniform motion tends to stay in uniform motion unless acted upon by a net external force.
Newton's Second Law states that an applied force, , on an object equals the rate of change of its momentum, , with time. Mathematically, this is expressed as :
If applied to an object with constant mass (dm/dt = 0), the first term vanishes, and by substitution using the definition of acceleration, the equation can be written in the iconic form
:
The first and second laws represent a break with the physics of Aristotle, in which it was believed that a force was necessary in order to maintain motion. They state that a force is only needed in order to change an object's state of motion. The SI unit of force is the newton, named in Newton's honour.
Newton's Third Law states that for every action there is an equal and opposite reaction. This means that any force exerted onto an object has a counterpart force that is exerted in the opposite direction back onto the first object. A common example is of two ice skaters pushing against each other and sliding apart in opposite directions. Another example is the recoil of a firearm, in which the force propelling the bullet is exerted equally back onto the gun and is felt by the shooter. Since the objects in question do not necessarily have the same mass, the resulting acceleration of the two objects can be different (as in the case of firearm recoil).
Unlike Aristotle's, Newton's physics is meant to be universal. For example, the second law applies both to a planet and to a falling stone.
The vector nature of the second law addresses the geometrical relationship between the direction of the force and the manner in which the object's momentum changes. Before Newton, it had typically been assumed that a planet orbiting the sun would need a forward force to keep it moving. Newton showed instead that all that was needed was an inward attraction from the sun. Even many decades after the publication of the Principia, this counterintuitive idea was not universally accepted, and many scientists preferred Descartes' theory of vortices.
Cartoons have gone further to suggest the apple actually hit Newton's head, and that its impact somehow made him aware of the force of gravity, though this is not reported in the biographical manuscript by William Stukeley, published in 1752, and made available by the Royal Society. It is known from his notebooks that Newton was grappling in the late 1660s with the idea that terrestrial gravity extends, in an inverse-square proportion, to the Moon; however it took him two decades to develop the full-fledged theory. John Conduitt, Newton's assistant at the Royal Mint and husband of Newton's niece, described the event when he wrote about Newton's life:
In the year 1666 he retired again from Cambridge to his mother in Lincolnshire. Whilst he was pensively meandering in a garden it came into his thought that the power of gravity (which brought an apple from a tree to the ground) was not limited to a certain distance from earth, but that this power must extend much further than was usually thought. Why not as high as the Moon said he to himself & if so, that must influence her motion & perhaps retain her in her orbit, whereupon he fell a calculating what would be the effect of that supposition.
The question was not whether gravity existed, but whether it extended so far from Earth that it could also be the force holding the moon to its orbit. Newton showed that if the force decreased as the inverse square of the distance, one could indeed calculate the Moon's orbital period, and get good agreement. He guessed the same force was responsible for other orbital motions, and hence named it "universal gravitation".
Stukeley recorded in his Memoirs of Sir Isaac Newton's Life a conversation with Newton in Kensington on 15 April 1726, in which Newton recalled:
when formerly, the notion of gravitation came into his mind. It was occasioned by the fall of an apple, as he sat in contemplative mood. Why should that apple always descend perpendicularly to the ground, thought he to himself. Why should it not go sideways or upwards, but constantly to the Earth's centre? Assuredly the reason is, that the Earth draws it. There must be a drawing power in matter. And the sum of the drawing power in the matter of the Earth must be in the Earth's centre, not in any side of the Earth. Therefore does this apple fall perpendicularly or towards the centre? If matter thus draws matter; it must be proportion of its quantity. Therefore the apple draws the Earth, as well as the Earth draws the apple."
In similar terms, Voltaire wrote in his Essay on Epic Poetry (1727), "Sir Isaac Newton walking in his gardens, had the first thought of his system of gravitation, upon seeing an apple falling from a tree."
Various trees are claimed to be "the" apple tree which Newton describes. The King's School, Grantham, claims that the tree was purchased by the school, uprooted and transported to the headmaster's garden some years later. The staff of the [now] National Trust-owned Woolsthorpe Manor dispute this, and claim that a tree present in their gardens is the one described by Newton. A descendant of the original tree can be seen growing outside the main gate of Trinity College, Cambridge, below the room Newton lived in when he studied there. The National Fruit Collection at Brogdale can supply grafts from their tree, which appears identical to Flower of Kent, a coarse-fleshed cooking variety.
