The buttered toast phenomenon is an observation that buttered toast tends to land butter-side down after it falls. It is used as an idiom representing pessimistic outlooks. [1] Various people have attempted to determine whether there is an actual tendency for bread to fall in this fashion, with varying results.
Written accounts can be traced to the mid-19th century. The phenomenon is often attributed to a parodic poem of James Payn from 1884: [2] [3]
I never had a slice of bread,
Particularly large and wide,
That did not fall upon the floor,
And always on the buttered side!
In the past, this has often been considered just a pessimistic belief. A 1991 study by the BBC's television series Q.E.D. found that when toast is tossed into the air, it lands butter-side down just one-half of the time (as would be predicted by chance). [4] However, several scientific studies have found that when toast is dropped from a table (as opposed to being thrown in the air), it more often falls butter-side down. [5] [6] [7] A study on this subject by Robert Matthews won the Ig Nobel Prize for physics in 1996. [8] [9]
When toast falls out of one's hand, it does so at an angle causing the toast to rotate. Given that tables are usually between two and six feet (0.7 to 1.83 meters), there is enough time for the toast to rotate about one-half of a turn, and thus lands upside down relative to its original position. Since the original position is usually butter-side up, the toast lands butter-side down. [10] However, if the table is over 10 feet (3.0 meters) tall, the toast will rotate a full 360 degrees, and land butter-side up. [11] Also, if the toast travels horizontally at over 3.6 miles per hour (1.6 m/s), the toast will not rotate enough to land butter-side down. [4]
Professor Robert Matthews argued that the phenomenon is ultimately based in the fundamental physical constants. His reasoning was as follows. The height of the table from which a toast usually falls is directly related to the height of humans. Matthews proceeds to deduce the limits for a safe average human height from a simple chemical bond model: if a skull is higher than three meters from the ground, then a fall will lead to its fracture due to fracture of the chemical bonds after its acceleration under the Earth gravity. And here are the physical constants in question, quoting professor Matthews: "the electromagnetic fine-structure constant - determines the strength of the chemical bonds in the skull, while the second - the gravitational fine-structure constant - determines the strength of gravity. Finally, the so-called Bohr radius dictates the size of atoms making up the body.". [8] For this work Matthews earned the 1996 Ig Nobel Prize in physics. [12]
The added weight of the butter has an effect on the falling process, [13] since the butter spreads throughout the slice. [4] A piece of toast has inertia as it flips towards the floor, preventing its spin from stopping easily; it is usually only stopped by hitting the floor. This moment of inertia is determined by the speed at which the toast is flipping, combined with the size and mass of the toast. Because most toast is relatively uniform, they often land in a similar manner. [14]
The buttered cat paradox is a question that asks if toast always lands butter side down and cats always land on their feet, what would happen if a slice of toast were attached butter-side-up to the back of a dropped cat? [15]
A Wise Man of Chelm joke recounts a housewife being amazed at a slice of bread falling buttered side up one morning, contrary to the idiom. After consulting the elders at the synagogue at some length, they conclude: "Madam, the problem is that you have buttered the wrong side of the bread." [16]
Murphy's law is an adage or epigram that is typically stated as: "Anything that can go wrong will go wrong." In some formulations, it is extended to "Anything that can go wrong will go wrong, and at the worst possible time."
Sod's law, a British culture axiom, states that "if something can go wrong, it will". The law sometimes has a corollary: that the misfortune will happen at "the worst possible time". The term is commonly used in the United Kingdom.
French toast is a dish of sliced bread soaked in beaten eggs and often milk or cream, then pan-fried. Alternative names and variants include eggy bread, Bombay toast, gypsy toast, and poor knights (of Windsor).
A toaster is a small electric appliance that uses radiant heat to brown sliced bread into toast the color caused from the Maillard reaction. It typically consists of one or more slots into which bread is inserted, and heating elements, often made of nichrome wire, to generate heat and toast the bread to the desired level of crispiness.
A pitch drop experiment is a long-term experiment which measures the flow of a piece of pitch over many years. "Pitch" is the name for any of a number of highly viscous liquids which appear solid, most commonly bitumen, also known as asphalt. At room temperature, tar pitch flows at a very low rate, taking several years to form a single drop.
Danish cuisine originated from the peasant population's own local produce and was enhanced by cooking techniques developed in the late 19th century and the wider availability of goods during and after the Industrial Revolution. Open sandwiches, known as smørrebrød, which in their basic form are the usual fare for lunch, can be considered a national speciality when prepared and garnished with a variety of ingredients. Hot meals are typically prepared with meat or fish. Substantial meat and fish dishes includes flæskesteg and kogt torsk with mustard sauce and trimmings. Ground meats became widespread during the industrial revolution and traditional dishes that are still popular include frikadeller, karbonader and medisterpølse. Denmark is known for its Carlsberg and Tuborg beers and for its akvavit and bitters, but amongst the Danes themselves imported wine has gained steadily in popularity since the 1960s.
The ladder paradox is a thought experiment in special relativity. It involves a ladder, parallel to the ground, travelling horizontally at relativistic speed and therefore undergoing a Lorentz length contraction. The ladder is imagined passing through the open front and rear doors of a garage or barn which is shorter than its rest length, so if the ladder was not moving it would not be able to fit inside. To a stationary observer, due to the contraction, the moving ladder is able to fit entirely inside the building as it passes through. On the other hand, from the point of view of an observer moving with the ladder, the ladder will not be contracted, and it is the building which will be Lorentz contracted to an even smaller length. Therefore, the ladder will not be able to fit inside the building as it passes through. This poses an apparent discrepancy between the realities of both observers.
Beer head is the frothy foam on top of beer and carbonated beverages which is produced by bubbles of gas, predominantly carbon dioxide, rising to the surface. The elements that produce the head are wort protein, yeast and hop residue. The carbon dioxide that forms the bubbles in the head is produced during fermentation as yeasts break down sugar-rich molecules to produce ethanol and carbon dioxide. The carbonation can occur before or after bottling the beer. If the beer continues fermenting in the bottle, then it naturally carbonates and the head is formed upon opening and/or pouring the beer. If the beer is pasteurized or filtered then the beer must be force carbonated using pressurized gas.
Bell's spaceship paradox is a thought experiment in special relativity. It was first described by E. Dewan and M. Beran in 1959 but became more widely known after John Stewart Bell elaborated the idea further in 1976. A delicate thread hangs between two spaceships headed in the same direction. They start accelerating simultaneously and equally as measured in the inertial frame S, thus having the same velocity at all times as viewed from S. Therefore, they are all subject to the same Lorentz contraction, so the entire assembly seems to be equally contracted in the S frame with respect to the length at the start. At first sight, it might appear that the thread will not break during acceleration.
In German cuisine, Butterbrot is a slice of bread topped with butter. Also known as boterham in Dutch speaking countries, it is still considered Butterbrot or boterham even if additional toppings, such as cheese, spreads, or lunch meats, are added, as long as it begins with a slice of bread with butter.
The cat righting reflex is a cat's innate ability to orient itself as it falls in order to land on its feet. The righting reflex begins to appear at 3–4 weeks of age, and is perfected at 6–9 weeks. Cats are able to do this because they have an unusually flexible backbone and no functional clavicle (collarbone). The tail seems to help but cats without a tail also have this ability, since a cat mostly turns by moving its legs and twisting its spine in a certain sequence.
Barmbrack, also often shortened to brack, is a yeast bread with added sultanas and raisins. The bread is associated with Halloween in Ireland, where an item is placed inside the bread, with the person receiving it considered to be fortunate.
The buttered cat paradox is a common joke based on the combination of two adages:
Robert A. J. Matthews, is a British physicist and science writer.
A Wilberforce pendulum, invented by British physicist Lionel Robert Wilberforce around 1896, consists of a mass suspended by a long helical spring and free to turn on its vertical axis, twisting the spring. It is an example of a coupled mechanical oscillator, often used as a demonstration in physics education. The mass can both bob up and down on the spring, and rotate back and forth about its vertical axis with torsional vibrations. When correctly adjusted and set in motion, it exhibits a curious motion in which periods of purely rotational oscillation gradually alternate with periods of purely up and down oscillation. The energy stored in the device shifts slowly back and forth between the translational 'up and down' oscillation mode and the torsional 'clockwise and counterclockwise' oscillation mode, until the motion eventually dies away.

Toast is sliced bread that has been browned by radiant heat. The browning is the result of a Maillard reaction altering the flavor of the bread and making it firmer. The firm surface is easier to spread toppings on and the warmth can help butter reach its melting point. Toasting is a common method of making stale bread more palatable. Bread is commonly toasted using a toaster or a toaster oven. Toast may contain acrylamide caused by the browning process, which is suspected to be a carcinogen. However, claims that acrylamide in burnt toast causes cancer have not been proven.
A peanut butter and jelly sandwich (PB&J) consists of peanut butter and fruit preserves—jelly—spread on bread. The sandwich may be open-faced, made of a single slice of bread folded over, or made using two slices of bread. The sandwich is popular in the United States, especially among children; a 2002 survey showed the average American will eat 1,500 peanut butter and jelly sandwiches before graduating from high school. There are many variations of the sandwich, starting with the basic peanut butter sandwich or jam sandwich.
The cuisine of St. Louis is largely influenced by the city’s German, Irish, Italian, Mexican, Chinese, and Vietnamese immigrant population and African Americans who migrated from the Southern United States.
