Trouble. When you hear this word, you immediately recall the hard times of turmoil in Ancient Russia, think about the unrest of the people and the crisis. In fact, it is also a unit of measure equal to 1.7 meters. And it appeared in 1958, when Oliver Smoot, who was studying at that time at the Massachusetts Institute of Technology, was offered by friends to measure the bridge between Boston and Cambridge. And the ruler was Smoot himself. He just lay down on the ground, after which the cheerful students made notes. The operation was repeated until the bridge ended. As a result of unusual measurements, it turned out that the length of the Harvard Bridge is 364.4 cm and one more ear. Even today, these marks can be seen on the bridge. And although the object was reconstructed in 1988, the police asked to keep the historical marks. And the point here is not at all in the sense of humor of law enforcement agencies. It was just that with the help of marks-troubles, the police could easily determine the location of the accident. Smoot turned out to be such a popular measurement system that it is even present in Google's calculator and in the Google Earth program. And the student, who became the hero of an unusual experiment and made his body a new unit of measurement, eventually headed the International Organization of Standards. It's good that Troubles had enough humor not to make the new unit standard for everyone.
Big Mac Index. It turns out that Big Mac is not just a famous sandwich from a famous restaurant chain. For example, in 2012, for $ 50, you could buy 23 Big Macs in the Ukrainian McDonald's, the same as in Hong Kong. For example, Argentina artificially raised the prices of Big Macs, trying to look better and more prosperous relative to its competitors.
The "Waffle House" method. The Vafelny Domik restaurant chain is proud not only of the quality of its product, but also of the stability of its work. It is believed that any visitor, regardless of the weather, can taste delicious waffles and pastries here. The stability of waffle restaurants has even become a kind of standard for the US Federal Emergency Management Agency. After all, you can evaluate the conditions that are happening around. If the restaurant works, then everything is not so bad. Even if the Waffle House was closed, the disaster was so serious that immediate assistance was required.
Sting pain index. When people report pain, they don’t think it can be measured in any other way. Entomologist Justin Sting created a scale that estimates the pain index that is present after an insect bite. The ruler readings range from zero to four points. Zero is a barely noticeable inconvenience, but a four means a strong painful shock, which can make a person fall to the floor and even lose consciousness. It turns out that there are insects in nature that are capable of rewarding with severe pain. For example, the Tarantula Hawk wasp is the creature whose bite will reward a person with fourth degree pain on the Sting scale.
Stress level on the Holmes and Rache scale. People have learned to measure such an elusive thing as stress. A special scale was created, the critical bar on which is 300 points. It is believed that those with a higher stress score are at risk of either going insane or even dying. And such a scale was developed in 1967 by scientists Thomas Holmes and Richard Rahe. They are closely engaged in the study of human stress, evaluating 43 most common events in our life. This is how a scale was created that assesses the impact of factors harmful to mental health. The death of a loved one was assessed by Holmes and Rahe at 100 points, problems at work - at 23 points, the coming Christmas was given 12 points, vacation - 13 points. Even a minor offense is stressful, estimated at 11 points.
Jolie. In this case, the units are really tied to the Hollywood actress. But what can you measure with it? Sexuality or lip volume? In fact, her name has become a unit of measurement for much more serious things. It's no secret that the actress is actively involved in humanitarian programs, helping, in particular, people from the Third World. Angelina Jolie even adopted several children from various poor countries. In honor of her, the Jolie unit of measurement was invented, which determines what kind of international assistance a country receives after calling the attention of some world celebrity. For example, in 2005, the Republic of the Congo had a per capita income of $ 11. And in Darfur, a region of Sudan, where economic conditions were similar, after Jolie's charitable visit, income grew to $ 300. Thus, the population has become richer at times.
Muta. It is believed that martial arts develop patience and endurance in a person. Real fighters cannot be confused with abrasions, bruises and the sight of blood. But sometimes the blood loss can be serious. In battles, a rule scale is used to determine the brutality and bloodiness of the battle for the rules. One scratch received by the fighter is equal to the tenth muta. The most serious damage is assessed as a whole muta. In 1992, a wrestler nicknamed "The Great Muta" even entered history. The fact is that his injuries received by him were rated as one on the bloodiness scale. And the fight with his participation became the bloodiest in the history of fighting without rules in Japan.
Skyville. This unusual unit is designed to measure the amount of capsaicin in chili peppers. Thanks to the skill, you can understand how hot and pungent the product is. And if Justin Schmidt tried the whole scale on himself, then the author of this measurement scale decided not to try a bunch of different hot peppers. He acted much smarter. For this, essential oils were extracted from plants, which, under certain conditions, can generate heat. And the level of pungency could be determined using the amount of sugar and water that had to be added to the oil to stop heat generation. The more additives were required, the higher the skill level. For example, Trinidad Moruga Scorpion pepper oil had to be diluted one and a half to two million times before it could be suitable for human consumption. Interestingly, that pepper spray, which is used by many for self-defense, is about one notch up the scale with this hot pepper.
Micromort. This unit of measure indicates how much the risk of death increases when performing normal daily activities. For example, one micromort is, in fact, a chance in a million. This is the risk of death for those who have been living on the territory of a nuclear power plant for five years, who have been drinking tap water in Miami for a year, who have been in New York for two days, or who have been in a coal mine for an hour.
Belgium and Wales. The British generally have a fairly large practice of using non-standard descriptive units of measurement. Here they can evaluate the area with football fields, or Olympic pools. But Wales and Belgium are considered the strangest of descriptive units. It's about the size of the countries. For Wales, this is about 20 thousand square kilometers. Such an assessment appeared in the days of the British Empire. With its help, it was possible to describe the size of remote regions, about which the British had a vague idea. So at the beginning of the Vietnam War, the media simply described that this is a country in Southeast Asia, whose size is 14 Wales. And after the accession of Great Britain to the European Union, Wales was simply replaced by Belgium. The new unit turned out to be one and a half times larger than the previous one. But now such a measuring instrument has become much more international.
Banana equivalent. There are many ways to measure radiation. Most of them were named after certain scientists - Geiger, Roentgen, Sievert. But the banana equivalent doesn't look particularly scientific at first. In fact, by eating each such fruit, we receive a small portion of radiation into the body. It is 0.1 microsieverts. It is obvious that this dose is harmless, but with its help it is possible to estimate quite real exposure. For example, in order to get the radiation that splashed out due to the accident at the Japanese Fukushima, you would have to eat as many as 76 million bananas. It is interesting that such an unusual unit of measurement, the banana equivalent, was invented by comedians as a joke. It all started with a well thought out table in a popular comic magazine. However, soon this unit began to be used by quite respected Forbes and BBS, thanks to its ease and availability.
Crab. The unit of measurement sounds like it is meant to measure what kind of underwater creatures. In fact, this "crab" has nothing to do with arthropods. Crabs and their derivatives, millicrabs, are used to express the intensity of radiation sources in space. This illogical name actually comes from the Crab Nebula, a large remnant of an ancient supernova. It is known for intensely and continuously emitting cosmic X-rays. The Crab Nebula has become the best standard for cosmic radiation, replacing much more inconvenient metric prototypes. However, recently scientists have discovered that the radiation is no longer as stable as previously thought. So the eligibility of "crab" to be the standard is currently being challenged by some scholars.
The bearded second. In physics and technology there are many different measurement systems, and there are really funny ones. Among them is a secondary beard. It is a measure of short length, which is defined as the distance over which beard hair grows on average in one second. This unit appeared, being inspired by the light year and as a kind of parody of it. But it is not easy to determine exactly the bearded second, because there is simply no standard for a beard and its height. Despite this, it was still possible to establish the value of this strange unit - it is about 5 nanometers. This is based on the fact that there are about 31.5 million seconds per year, and a standard beard grows 15 centimeters during this time.
Sidharb. To those who have visited Australia, this unit may seem familiar. The fact is that on this continent it appears not only in colloquial speech, but even in official documents. Such a strange name is used to measure a large volume of water. The Gulf of Sydney was taken as a reference, it is used roughly like Wales and Belgium for area comparison. One sidharb is about 562 thousand megalitres of water, which are found near Sydney at high tide. Is it any wonder that such a strange unit has not gained popularity anywhere outside Australia?
Furlong, Firkin and Fortnight (FFF) system. Often, unusual systems of measurement appear simply as jokes or silly ideas from someone. It's just that over time, this idea is picked up by others. But the FFF system appeared in a different way, in its own way. This is a rare case of the existence of an arbitrary measurement system, which is completely built on the parody of other systems. It contains three main dimensions - length, mass and time. One furlong is 200 meters, firkin is 40 kilograms, and a fortnight is 1.2 million seconds or two weeks. Fortnight is based on the old English system of measurement, and the other two are deliberately ridiculous. And even if these three basic units, like their many derivatives, are just a playful version of real systems, even FFF has its own benefits. Any new ridiculous system of measurement is immediately called "furlong for fortnight" and "firkin for fortnight". Such jokes have already become classic. A microffortnight of 1.2096 seconds is even used in conjunction with other classic methods of measuring time. The joke of engineers was even supported by Google, allowing you to work with this unit of time in your calculator.
Savard. Music seems beautiful and intangible. Nevertheless, it was also possible to associate it with mathematics. The Savard scale helps in this, which closely links the two opposites. And the basis of the measurement system is Savar, which is 1/301 octave. This musical interval separates two identical notes. For those who are guided in the theory of music, savar is a very convenient approximate unit of measurement. In some situations it turns out to be useful to operate with it. And although such a measurement system seems complicated and even incomprehensible, two people managed to invent it twice independently of each other. The first was Joseph Savard, who in 1696 invented this unit, giving it the name "eptamerid". The fact is that the modern savar was the seventh part of the merida, the logarithmic value of the interval, invented by the same scientist. Already in the twentieth century, the French physicist Felix Savard began to promote this unit of measurement, to prove its right to exist. He also gave her his name.
Erlang. This unit of measurement is quite common, to the surprise of many. We encounter it every day, although we do not think about it. It's just that every time we talk on the phone, an invisible counter counts erlangs - this unit of measurement is needed to count telecommunications traffic. One erlang is equal to an hour of continuous voice traffic. And erlang measurements are very important. After all, this is how engineers can understand the operation of a telecommunications network and create one that can withstand a heavy load. And this unit of measurement was created in honor of Agner Klarup Erlang. This one was a great but eccentric engineer. But thanks to his talent, he was able to practically single-handedly create the entire scientific direction of the analysis of telephone networks.
Barn. This unit of measurement, by its name, speaks eloquently that it is associated exclusively with agriculture. The fact is that "barn" in translation from English means a barn or cowshed. Surprisingly, this value has nothing in common with cattle. And they use "barn" in elementary particle physics. This value, as well as its derivatives, femtobarn and attobarn, is used to calculate the number of particles hitting the detector in experiments with the collider. The term was first used in June 1943, when it appeared in reports from a secret laboratory at Los Alamos. Scientists have tried to use other units - "Oppenheimer" and "Bethe", but they turned out to be too complex for constant use. Then, thanks to scientists living in the countryside, a new unit of measurement appeared. After all, the barn for these people was part of a serene past.
Wheaton. The modern technological society gives us not only new opportunities for communication, but also tools for measuring it. After the famous actor Wil Wheaton gained half a million followers on his Twitter, his name began to be called a unit of popularity. So Wheaton appeared, who can be used to evaluate the success in this social network.On average, a Twitter user has about 150 friends, so his success rate is 300 microWitons.
Gilet. This unit of measurement also shows how everyday objects become part of science. With the help of the Vest, they began to measure the power of the laser. It is believed that a laser with an indicator of five such units can burn exactly five blades of the famous manufacturer.
Mickey. This unit was named after Mickey Mouse. With its help, mouse movements are measured, but not cartoon, but computer. One Mickey shows the shortest mouse movement, about 0.1 millimeters. It is this value that the computer is capable of processing.
Needle. Computer users know that information is measured in bytes. This one consists of eight bits - zeros or ones. But there is a term niddle, which is exactly half a byte.
