Take a free opposition and reposition quiz to test your knowledge, or review our opposition and reposition video. See a demonstration of opposition and reposition in the anatomy review video below: During reposition, the thumb and finger return to their original position. ![]() Reposition is the opposite action of opposition. In fact, think about this: when the opposition movement occurs, what happens? In the picture above, did you notice how the thumb and finger created a shape similar to the letter ‘O’? The ‘O’ stands for opposition! Now you can easily remember this motion of our opposable thumbs! Reposition of the Thumb Opposition is the special movement of our opposable thumbs. A super easy way to remember this is that you’ve probably heard someone say that humans have opposable thumbs. Opposable thumbs not only impact our lives, but they also function as powerful. ![]() Opposition of the thumb occurs when the tip of the thumb comes to meet (and oppose) the tip of another finger from the same hand. Definition of opposable 1 : capable of being opposed or resisted 2 : capable of being placed against one or more of the remaining digits of a hand or foot the opposable human thumb What is the advantage of an opposable thumb Benefits of opposable thumbs. Thanks to this saddle joint, the thumb can perform circumduction, flexion and extension, abduction and adduction, as well as special movements called opposition and reposition. They call it a saddle joint because, well, it kinda looks like a saddle (yee-haw, cowboy!). The thumb, also known as the pollex or digit one, articulates (forms a joint) with the trapezium bone of the wrist (carpus) via a saddle joint, which is a type of synovial joint featuring interlocking convex and concave surfaces.

3/23/2023 0 Comments Degrees of freedom![]() We can take some random values for the sample. We are free to choose the elements but the mean value should be 4. This becomes the constraint for the test. Now, say that the mean of the 6 value should be 4. Hence the degree of freedom, in this case, will be 6. Now, if there are no conditions or constraints attached, these six integers are free to take up any values. Therefore 4 is the degree of freedom in this case.Įxample 2: If we are to take an example statistically, we can take six integers. Hence we could say that for 5-1 = 4 days, she had the chance to vary the shoes. This arises due to the constraint that she must not choose the used shoes again. Unlike the previous days, she couldn’t vary her choice. On the fifth day, there is no choice left for her. This could be continued until the last day, where she could wear the only remaining pair. Hence she could choose from the remaining four. The next day she could choose all but the shoes she wore the previous day. ![]() On the first day, she could choose any of the five pair of shoes. A constrain is placed on her that she has to wear a different pair of shoes each day for the next five days. She could wear any of them according to her preference. Let us understand the degrees of freedom more clearly by taking an example.Įxample 1: Let us say that a girl has five pair shoes. It can also be zero in the case of a sample with only one individual value. The degree of freedom is a positive whole number. Where N is the number of independent values taken for the sample. That is, n-1 independent values in the sample that is being considered have the freedom to vary. If we are to take a sample of size n, then typically, the degree of freedom for this sample will be the sample size minus 1. The degree of freedom is not precisely the sample size. Here the degree of freedom has the value of the sample size.ĭegrees of freedom often have applications in the calculation of population parameters from the sample statistics. If there are no rules, limitations, or patterns to be followed, then all the independent values have the freedom to vary. ![]() It is the freedom of variables to vary or change while strictly staying within the constraints. These variations are in such a way that the constraints of the test are not compromised. It can be thought of as a mathematical restriction that should be implemented while estimating a population parameter by estimating others. What is Degrees of Freedom?ĭegrees of freedom indicates the values in a sample test that can vary in the estimation of parameters. Symbol: ( Df ) is the commonly used abbreviation for the degree of freedom. It is the amount of independent information that goes into the calculation of an estimate. This is an essential concept in statistics including regression analysis, hypothesis test, and parameter estimation. In the estimation of a statistical parameter, this can be described as the number of values that can vary. For a similar discussion of the problems with data-dependent analysis, or the ‘garden of forking paths’, see this great article by Gelman and Loken (2014).The degree of freedom is defined as the number of independent values that can vary in any analysis without breaking the constraints of the analysis. (2011) discovered that these researcher degrees of freedom “made it unacceptably easy (.) to accumulate (and report) statistically significant evidence for a false hypothesis” and to “present anything as significant” (p. Given this flexibility, it is all too alluring to dredge your data until you finally find a significant effect. More precisely, in the course of collecting and analyzing data, researchers have the option to flexibly make a range of decisions - whether or not to collect more data, to exclude some observations, to include control variables, to combine or transform measures, or to report only a subset of experimental conditions. ![]() Amongst others, Simmons and colleagues reported a finding that listening to a Beatles song made their participants become younger – their age supposedly decreased! This impossible finding only became possible after engaging in what is called questionable research practices (QRPs). In an article published in 2011, Simmons, Nelson, and Simonsohn (2011) have raised concerns about researcher degrees of freedom and the extent to which they can increase the chances of false-positive findings. One example for how bad it can get can be taken from psychology. To minimize the chances of misleading yourself, being misled, and mistakenly believing in effects that in fact are spurious, we highly recommend that you read on! If you want to do solid and meaningful science, then it’s vital to not fool yourself as part of the research process. In the past 5–10 years, many scientific disciplines have come under fire for shoddy research practices, perverse incentives, and a lack of transparency and openness. 3/23/2023 0 Comments Mirror reflection quotes“Rumi, who is one of the greatest Persian poets, said that the truth was a mirror in the hands of God.That is my idea of what I’d like to look like.” ~ Cher “I’m insecure about everything, because I’m never going to look in the mirror and see this blond, blue-eyed girl.“Shadows cannot see themselves in the mirror of the sun.” ~ Evita Peron.“The world is a mirror representing the divine life.” ~ William A.“If art reflects life, it does so with special mirrors.” ~ Bertolt Brecht.“All sorts of things in this world behave like mirrors.” ~ Jacques Lacan.“The world is the mirror of myself dying.” ~ Henry Miller.“A game is like a mirror that allows you to look at yourself.” ~ Robert Kiyosaki.“Life is for each man a solitary cell whose walls are mirrors.” ~ Eugene O’Neill.“A true soul mate is a mirror, the person who shows you everything that is holding you back, the person who brings you to your own attention so you can change your life.” ~ Elizabeth Gilbert.You can ask forgiveness of others, but in the end the real forgiveness is in one’s own self.” ~ Maya Angelou ![]() “If we all hold on to the mistake, we can’t see our own glory in the mirror because we have the mistake between our faces and the mirror we can’t see what we’re capable of being.“How can mirrors be real if our eyes aren’t real?” ~ Jaden Smith.Logic is transcendental.” ~ Ludwig Wittgenstein “Logic is not a body of doctrine, but a mirror-image of the world.“Before you leave the house, look in the mirror and remove one accessory.” ~ Coco Chanel.“We go forward looking in the rearview mirror.” ~ Marshall McLuhan.“Never believe in mirrors or newspapers.” ~ Tom Stoppard.The world is what you are.” ~ Thomas Dreier If you are loving, if you are friendly, if you are helpful, the world will prove loving and friendly and helpful to you. ![]() “That meek darkness be thy mirror, and thy whole remembrance.” ~ Dionysius of Halicarnassus.“Maturity is when all of your mirrors turn into windows.” ~ Henry David Thoreau.“You use a glass mirror to see your face you use works of art to see your soul.” ~ George Bernard Shaw.“Everything in your life, every experience, every relationship is a mirror of the mental pattern that is going on inside of you.” ~ Louise Hay.They let one pass through the surface of things.” ~ Claude Chabrol “Who sees the human face correctly: the photographer, the mirror, or the painter?” ~ Pablo Picasso.Never, never shall we know what they are when they are alone or what is behind them.” ~ Erich Maria Remarque “Mirrors are there when we are and yet they never give anything back to us but our own image.“The pure heart is a spotless mirror in which images of infinite beauty are reflected.” ~ Rumi.“I stare at the mirror as I try to remember who I am and who I am not.” ~ Suzanne Collins.“Beauty is eternity gazing at itself in a mirror.” ~ Khalil Gibran.“Mirror, mirror on the wall, who’s the naughtiest of them all?” ~ Sara Shepard. ![]()
3/23/2023 0 Comments Lakehouse by altaWhile Snowflake's marketing has not run with the lakehouse terminology, preferring the term 'data cloud' to describe its ability to support multiple data processing and analytics workloads, AWS has very much picked up on it as a term to describe its combined portfolio of data and analytics services – placing its 'lake house architecture' front and center of its data and analytics announcements at re:Invent 2020. In fact, the first use of the term by a vendor we have found can be attributed to Snowflake, which in late 2017 promoted that its customer, Jellyvision, was using Snowflake to combine schemaless and structured data processing in what Jellyvision described as a data lakehouse. Amazon Web Services (AWS) previously used the term (or in its case, 'lake house') in late 2019 in relation to Amazon Redshift Spectrum, its service that enables users of its Amazon Redshift data warehouse service to apply queries to data stored in its Amazon S3 cloud service. Often uttered flippantly to describe the result of the theoretical combination of a data warehouse with data lake functionality, usage of the term became more serious and more widespread in early 2020 as Databricks adopted it to describe its approach of marrying the data structure and data management features of the data warehouse with the low-cost storage used for data lakes.ĭatabricks was not the first to start using the data lakehouse terminology, however. The term 'data lakehouse' entered the data and analytics lexicon over the last few years. 3/23/2023 0 Comments Anemometer weather instruments![]() Wind vane and windsock are two other old tools for measing wind direction.They are used extensively by many sportsmen for whom knowing wind speed is important: kitesurfers, paragliders, and others. You can use them to measure the wind speed wherever you are. Wind meters or pocket anemometers are kind of like pocket thermometers.So that’s the wind you see in the weather forecast is always measured at this heigh. Such instruments are also called "cup anemometers". What is important to know about them is that they are usually set at an altitude of 10 meters (32 feet) above sea level, which is the optimal altitude for measuring the wind. In the process, they capture and measure wind speed and direction. This is a small tool that usually consists of a base and three cups that rotate on the spire. Anemometer is the most common of these wind instruments.There is more than one instrument for measuring wind, сonsidering that this is probably the most diverse weather parameter: Photo: Wikipedia Wind measurement instruments In meteorology and the natural sciences, a thermometer measures the temperature of the various environment: air, sea surface, soil, and more. Thermometer is the smallest, simplest, and most common weather instrument everyone has at home, no matter how much you know about the weather. That is, usually one corresponding instrument is used to measure one parameter. These can be analog instruments as well as electronic ones, and there are more and more of the latter. The number of basic weather tools is roughly equal to the number of weather parameters. So let’s take a look at what weather instruments are and what are their main features. Follow the links to learn more about some tools, particularly the stations, satellites and radars that are the most interesting and common in meteorology today. The latter was created relatively recently with the development of technology. The first group of instruments have been around for centuries, but have not yet disappeared, it is still in active use. ![]() An example of the first is the most common home thermometer to measure air temperature, an example of the second is weather stations that you probably know about, too, if you are interested in meteorology. ![]() There are more than two dozens of them, but they can all be divided into two groups: small and basic, and big and complex. You can call them gadgets or devices in a modern way. We collect weather data with various weather instruments. Figuratively speaking, it is followed by the larger central part - the weather model that makes the forecast, and the base - the meteorological data about winds, precipitation, and so on. The weather forecast you see in the weather app or the website is just the tip of the iceberg. 3/22/2023 0 Comments Diffraction orderRainbow-like colors from closely spaced narrow tracks on optical data storage disks such as CDs or DVDs are an example of light diffraction caused by diffraction gratings. Ī diffraction grating can create "rainbow" colors when it is illuminated by a wide- spectrum (e.g., continuous) light source. Rogers (1804–1882) took over the lead and, by the end of the 19th century, the concave gratings of Henry Augustus Rowland (1848–1901) were the best available. Gratings with the lowest line-distance (d) were created, in the 1860s, by Friedrich Adolph Nobert (1806–1881) in Greifswald then the two Americans Lewis Morris Rutherfurd (1816–1892) and William B. Using these principles, Fraunhofer was the first who used a diffraction grating to obtain line spectra and the first who measured the wavelengths of spectral lines with a diffraction grating. The principles of diffraction were discovered by Thomas Young and Augustin-Jean Fresnel. ![]() This was similar to notable German physicist Joseph von Fraunhofer's wire diffraction grating in 1821. The first man-made diffraction grating was made around 1785 by Philadelphia inventor David Rittenhouse, who strung hairs between two finely threaded screws. James Gregory (1638–1675) observed the diffraction patterns caused by a bird feather, which was effectively the first diffraction grating (in a natural form) to be discovered, about a year after Isaac Newton's prism experiments. There are also gratings that modulate the phases of incident waves rather than the amplitude, and these type of gratings can be produced frequently by using holography. Such a grating modulates the amplitude of an incident wave on it to create a diffraction pattern. įor typical applications, a reflective grating has ridges or rulings on its surface while a transmissive grating has transmissive or hollow slits on its surface. Because of this, diffraction gratings are commonly used in monochromators and spectrometers, but other applications are also possible such as optical encoders for high precision motion control and wavefront measurement. The grating acts as a dispersive element. The directions or diffraction angles of these beams depend on the wave (light) incident angle to the diffraction grating, the spacing or distance between adjacent diffracting elements (e.g., parallel slits for a transmission grating) on the grating, and the wavelength of the incident light. The emerging coloration is a form of structural coloration. In optics, a diffraction grating is an optical component with a periodic structure that diffracts light into several beams travelling in different directions (i.e., different diffraction angles). ![]() An incandescent light bulb viewed through a diffractive effects filter. 3/22/2023 0 Comments Does google duo use data![]() ![]() It takes some tapping, but it also makes the process much safer.
