Homogeneity (physics)
In physics, a homogeneous material or system has the same properties at every point; it is uniform without irregularities. A uniform electric field (which has the same strength and the same direction at each point) would be compatible with homogeneity (all points experience the same physics). A material constructed with different constituents can be described as effectively homogeneous in the electromagnetic materials domain, when interacting with a directed radiation field (light, microwave frequencies, etc.).
Mathematically, homogeneity has the connotation of invariance, as all components of the equation have the same degree of value whether or not each of these components are scaled to different values, for example, by multiplication or addition. Cumulative distribution fits this description. "The state of having identical cumulative distribution function or values".
Context
The definition of homogeneous strongly depends on the context used. For example, a composite material is made up of different individual materials, known as "constituents" of the material, but may be defined as a homogeneous material when assigned a function. For example, asphalt paves our roads, but is a composite material consisting of asphalt binder and mineral aggregate, and then laid down in layers and compacted.

Homogeneity and heterogeneity
Homogeneity and heterogeneity are concepts often used in the sciences and statistics relating to the uniformity in a substance or organism. A material or image that is homogeneous is uniform in composition or character (i.e. color, shape, size, weight, height, distribution, texture, language, income, disease, temperature, radioactivity, architectural design, etc.); one that is heterogeneous is distinctly nonuniform in one of these qualities.
The words homogeneous and heterogeneous come from Medieval Latin homogeneus and heterogeneus, from Ancient Greek ὁμογενής (homogenēs) and ἑτερογενής (heterogenēs), from ὁμός (homos, “same”) and ἕτερος (heteros, “other, another, different”) respectively, followed by γένος (genos, “kind”); -ous is an adjectival suffix.
The concepts are the same to every level of complexity, from atoms to populations of animals or people, and galaxies. Hence, an element may be homogeneous on a larger scale, compared to being heterogeneous on a smaller scale. This is known as an effective medium approach, or effective medium approximations.

Homogeneity (disambiguation)
Homogeneity is a sameness of constituent structure.
Homogeneity, homogeneous, or homogenization may also refer to:
In mathematics
In statistics
In chemistry

Species homogeneity
In ecology, species homogeneity is a lack of biodiversity. Species richness is the fundamental unit in which to assess the homogeneity of an environment. Therefore, any reduction in species richness, especially endemic species, could be argued as advocating the production of a homogenous environment.
Monocultures
Species migration

Heterogenous vs Homogenous (Definitions, Examples, & Practice)
When we discuss mixtures we can broadly classify them as heterogenous or homogenous. This is common question on chemistry quizzes and tests where you are given a mixture, for example salt water, and asked to determine whether is a heterogenous or homogenous mixture. The general definition is: Heterogenous: Not uniform (unevenly distributed). Examples: rocks in mud, salad, nails in sand Homogenous: Uniform composition (same throughout). Examples: salt water, smoke, alloys Note that you can have a mixture, like rock, water, and sugar that has hetero and homo components. In this case the rocks and sugar water are a heterogenous mixture. If we look just at the sugar dissolved in the water, this has a uniform/smooth composition and is therefore a homogenous solution. We can separa...

Structural Geology Course: Lecture 4 (Homogeneity & Heterogeneity of rocks in Structural Geology)
In structural geology, the concepts of homogeneity and heterogeneity refer to the uniformity or variability of rock properties at different scales, from the microscale to the macroscale. Homogeneous rocks have consistent properties throughout, such as uniform mineral composition, grain size, and texture. In contrast, heterogeneous rocks exhibit variability in their properties, often due to differences in mineralogy, grain size, or the presence of structural features like fractures and veins. Understanding the homogeneity and heterogeneity of rocks is crucial for structural geologists because it influences how rocks deform under stress and the development of geological structures.

When we discuss mixtures we can broadly classify them as heterogenous or homogenous. This is common question on chemistry quizzes and tests where you are given a mixture, for example salt water, and asked to determine whether is a heterogenous or homogenous mixture.
The general definition is:
Heterogenous: Not uniform (unevenly distributed).
Examples: rocks in mud, salad, nails in sand
Homogenous: Uniform composition (same throughout).
Examples: salt water, smoke, alloys
Note that you can have a mixture, like rock, water, and sugar that has hetero and homo components. In this case the rocks and sugar water are a heterogenous mixture. If we look just at the sugar dissolved in the water, this has a uniform/smooth composition and is therefore a homogenous solution.
We can separate both heterogenous and homogenous mixtures using their physicals properties. For example filtration, distillation, sorting based on size, or gravitational sorting based on density.

In structural geology, the concepts of homogeneity and heterogeneity refer to the uniformity or variability of rock properties at different scales, from the microscale to the macroscale. Homogeneous rocks have consistent properties throughout, such as uniform mineral composition, grain size, and texture. In contrast, heterogeneous rocks exhibit variability in their properties, often due to differences in mineralogy, grain size, or the presence of structural features like fractures and veins.
Understanding the homogeneity and heterogeneity of rocks is crucial for structural geologists because it influences how rocks deform under stress and the development of geological structures. At the microscale, homogeneity implies that the properties of the rock, such as its strength and elasticity, are consistent in all directions. This can lead to uniform deformation behavior and the development of simple structures in response to tectonic forces. In contrast, heterogeneous rocks may exhibit localized zones of weakness or strength, leading to complex deformation patterns and the formation of diverse geological structures.
As the scale of observation increases, the effects of rock homogeneity and heterogeneity become more pronounced. At the mesoscale, geological structures such as faults, folds, and joints may be influenced by variations in rock properties across different regions. Homogeneous rocks are more likely to deform uniformly and exhibit predictable structural geometries, whereas heterogeneous rocks may deform non-uniformly, leading to the development of complex fault networks, folding patterns, and fracture systems.
On a regional scale, the homogeneity and heterogeneity of rocks play a significant role in controlling the behavior of large-scale tectonic processes and the formation of major geological structures such as mountain ranges, rift zones, and sedimentary basins. Homogeneous rocks may exhibit more uniform responses to tectonic forces, resulting in the development of broad, gentle folds and thrust faults. In contrast, heterogeneous rocks may produce more localized and complex deformation patterns, characterized by intense faulting, folding, and fracturing.
The concepts of homogeneity and heterogeneity are important to structural geologists because they influence the mechanical behavior of rocks at different scales and control the development of geological structures. By understanding the distribution and variability of rock properties, structural geologists can better interpret deformation processes, predict geological hazards, and reconstruct the tectonic history of a region.

Learning to Disambiguate Strongly Interacting Hands via Probabilistic Per-Pixel Part Segmentation
3DV 2021 Oral Presentation: In natural conversation and interaction, our hands often overlap or are in contact with each other. Due to the homogeneous appearance of hands, this makes estimating the 3D pose of interacting hands from images difficult. In this paper we demonstrate that self-similarity, and the resulting ambiguities in assigning pixel observations to the respective hands and their parts, is a major cause of the final 3D pose error. Motivated by this insight, we propose DIGIT, a novel method for estimating the 3D poses of two interacting hands from a single monocular image. The method consists of two interwoven branches that process the input imagery into a per-pixel semantic part segmentation mask and a visual feature volume. In contrast to prior work, we do not decouple the s...

The name causality suggests that all effects must have specific causes, which is a concept unrelated to the common use of causality in physics, and is violated in some mainstream interpretations of quantum mechanics."

Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.
Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain
Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

3DV 2021 Oral Presentation: In natural conversation and interaction, our hands often overlap or are in contact with each other. Due to the homogeneous appearance of hands, this makes estimating the 3D pose of interacting hands from images difficult. In this paper we demonstrate that self-similarity, and the resulting ambiguities in assigning pixel observations to the respective hands and their parts, is a major cause of the final 3D pose error. Motivated by this insight, we propose DIGIT, a novel method for estimating the 3D poses of two interacting hands from a single monocular image. The method consists of two interwoven branches that process the input imagery into a per-pixel semantic part segmentation mask and a visual feature volume. In contrast to prior work, we do not decouple the segmentation from the pose estimation stage, but rather leverage the per-pixel probabilities directly in the downstream pose estimation task. To do so, the part probabilities are merged with the visual features and processed via fully-convolutional layers. We experimentally show that the proposed approach achieves new state-of-the-art performance on the InterHand2.6M dataset. We provide detailed ablation studies to demonstrate the efficacy of our method and to provide insights into how the modelling of pixel ownership affects 3D hand pose estimation.

Symposium Artificial Intelligence and Ceremony of Awards. 21 and 22 October 2019.
Understanding language is a hard task for a computer even in the era of deep learning. In this talk I will advocate the importance of interdisciplinary work for multilingual Natural Language Understanding: I will present current state-of-the-art results attained by joining forces between computer scientists and (computational) linguists, in order to address the knowledge acquisition bottleneck and scale up key tasks in word- and sentence-level semantics which enable computers to understand what is written in a text. I will also showcase innovative multilingual solutions developed in my research group and at Babelscape, a Sapienza startup company I co-founded.

"First planet" redirects here. For other systems of numbering planets, see Planet § History and etymology. For other uses, see Mercury (disambiguation).
Mercury is the first planet from the Sun and the smallest in the Solar System. In English, it is named after the ancient Roman god Mercurius (Mercury), god of commerce and communication, and the messenger of the gods. Mercury is classified as a terrestrial planet, with roughly the same surface gravity as Mars. The surface of Mercury is heavily cratered, as a result of countless impact events that have accumulated over billions of years. Its largest crater, Caloris Planitia, has a diameter of 1,550 km (960 mi) and one-third the diameter of the planet (4,880 km or 3,030 mi). Similarly to the Earth's Moon, Mercury's surface displays an expansive rupes system generated from thrust faults and bright ray systems formed by impact event remnants.

Mercury's sidereal year (88.0 Earth days) and sidereal day (58.65 Earth days) are in a 3:2 ratio. This relationship is called spin–orbit resonance, and sidereal here means "relative to the stars". Consequently, one solar day (sunrise to sunrise) on Mercury lasts for around 176 Earth days: twice the planet's sidereal year. This means that one side of Mercury will remain in sunlight for one Mercurian year of 88 Earth days; while during the next orbit, that side will be in darkness all the time until the next sunrise after another 88 Earth days.
Combined with its high orbital eccentricity, the planet's surface has widely varying sunlight intensity and temperature, with the equatorial regions ranging from −170 °C (−270 °F) at night to 420 °C (790 °F) during sunlight. Due to the very small axial tilt, the planet's poles are permanently shadowed. This strongly suggests that water ice could be present in the craters. Above the planet's surface is an extremely tenuous exosphere and a faint magnetic field that is strong enough to deflect solar winds. Mercury has no natural satellite.
As of the early 2020s, many broad details of Mercury's geological history are still under investigation or pending data from space probes. Like other planets in the Solar System, Mercury was formed approximately 4.5 billion years ago. Its mantle is highly homogeneous, which suggests that Mercury had a magma ocean early in its history, like the Moon. According to current models, Mercury may have a solid silicate crust and mantle overlying a solid outer core, a deeper liquid core layer, and a solid inner core. There are many competing hypotheses about Mercury's origins and development, some of which incorporate collision with planetesimals and rock vaporization.

Mercury's sidereal year (88.0 Earth days) and sidereal day (58.65 Earth days) are in a 3:2 ratio. This relationship is called spin–orbit resonance, and sidereal here means "relative to the stars". Consequently, one solar day (sunrise to sunrise) on Mercury lasts for around 176 Earth days: twice the planet's sidereal year. This means that one side of Mercury will remain in sunlight for one Mercurian year of 88 Earth days; while during the next orbit, that side will be in darkness all the time until the next sunrise after another 88 Earth days.
Combined with its high orbital eccentricity, the planet's surface has widely varying sunlight intensity and temperature, with the equatorial regions ranging from −170 °C (−270 °F) at night to 420 °C (790 °F) during sunlight. Due to the very small axial tilt, the planet's poles are permanently shadowed. This strongly suggests that water ice could be present in the craters. Above the planet's surface is an extremely tenuous exosphere and a faint magnetic field that is strong enough to deflect solar winds. Mercury has no natural satellite.
As of the early 2020s, many broad details of Mercury's geological history are still under investigation or pending data from space probes. Like other planets in the Solar System, Mercury was formed approximately 4.5 billion years ago. Its mantle is highly homogeneous, which suggests that Mercury had a magma ocean early in its history, like the Moon. According to current models, Mercury may have a solid silicate crust and mantle overlying a solid outer core, a deeper liquid core layer, and a solid inner core. There are many competing hypotheses about Mercury's origins and development, some of which incorporate collision with planetesimals and rock vaporization.

Mercury is the first planet from the Sun and the smallest in the Solar System. In English, it is named after the ancient Roman god Mercurius (Mercury), god of commerce and communication, and the messenger of the gods. Mercury is classified as a terrestrial planet, with roughly the same surface gravity as Mars. The surface of Mercury is heavily cratered, as a result of countless impact events that have accumulated over billions of years. Its largest crater, Caloris Planitia, has a diameter of 1,550 km (960 mi) and one-third the diameter of the planet (4,880 km or 3,030 mi). Similarly to the Earth's Moon, Mercury's surface displays an expansive rupes system generated from thrust faults and bright ray systems formed by impact event remnants.

This simple example of causality is given as public service for those, like me, who struggle a little with the plethora of wikipedia disambiguation articles on the term, all full of mathematical formulae, discussion of things like causal dynamical triangulation, and sentences like:
"Causality should not be confused with Newton's second law, which is related to the conservation of momentum, and is a consequence of the spatial homogeneity of physical laws. The name causality suggests that all effects must have specific causes, which is a concept unrelated to the common use of causality in physics, and is violated in some mainstream interpretations of quantum mechanics."

When we discuss mixtures we can broadly classify them as heterogenous or homogenous. This is common question on chemistry quizzes and tests where you are given a mixture, for example salt water, and asked to determine whether is a heterogenous or homogenous mixture.
The general definition is:
Heterogenous: Not uniform (unevenly distributed).
Examples: rocks in mud, salad, nails in sand
Homogenous: Uniform composition (same throughout).
Examples: salt water, smoke, alloys
Note that you can have a mixture, like rock, water, and sugar that has hetero and homo components. In this case the rocks and sugar water are a heterogenous mixture. If we look just at the sugar dissolved in the water, this has a uniform/smooth composition and is therefore a homogenous solution.
We can separate both heterogenous and homogenous mixtures using their physicals properties. For example filtration, distillation, sorting based on size, or gravitational sorting based on density.

In structural geology, the concepts of homogeneity and heterogeneity refer to the uniformity or variability of rock properties at different scales, from the microscale to the macroscale. Homogeneous rocks have consistent properties throughout, such as uniform mineral composition, grain size, and texture. In contrast, heterogeneous rocks exhibit variability in their properties, often due to differences in mineralogy, grain size, or the presence of structural features like fractures and veins.
Understanding the homogeneity and heterogeneity of rocks is crucial for structural geologists because it influences how rocks deform under stress and the development of geological structures. At the microscale, homogeneity implies that the properties of the rock, such as its strength and elasticity, are consistent in all directions. This can lead to uniform deformation behavior and the development of simple structures in response to tectonic forces. In contrast, heterogeneous rocks may exhibit localized zones of weakness or strength, leading to complex deformation patterns and the formation of diverse geological structures.
As the scale of observation increases, the effects of rock homogeneity and heterogeneity become more pronounced. At the mesoscale, geological structures such as faults, folds, and joints may be influenced by variations in rock properties across different regions. Homogeneous rocks are more likely to deform uniformly and exhibit predictable structural geometries, whereas heterogeneous rocks may deform non-uniformly, leading to the development of complex fault networks, folding patterns, and fracture systems.
On a regional scale, the homogeneity and heterogeneity of rocks play a significant role in controlling the behavior of large-scale tectonic processes and the formation of major geological structures such as mountain ranges, rift zones, and sedimentary basins. Homogeneous rocks may exhibit more uniform responses to tectonic forces, resulting in the development of broad, gentle folds and thrust faults. In contrast, heterogeneous rocks may produce more localized and complex deformation patterns, characterized by intense faulting, folding, and fracturing.
The concepts of homogeneity and heterogeneity are important to structural geologists because they influence the mechanical behavior of rocks at different scales and control the development of geological structures. By understanding the distribution and variability of rock properties, structural geologists can better interpret deformation processes, predict geological hazards, and reconstruct the tectonic history of a region.

Homogenous. Homogenous. These words are commonly confused, but Dictionary.com can help you keep them straight!
Homogeneity (physics)
In physics, a homogeneous material or system has the same properties at every point; it is uniform without irregularities. A uniform electric field (which has the same strength and the same direction at each point) would be compatible with homogeneity (all points experience the same physics). A material constructed with different constituents can be described as effectively homogeneous in the electromagnetic materials domain, when interacting with a directed radiation field (light, microwave frequencies, etc.).
Mathematically, homogeneity has the connotation of invariance, as all components of the equation have the same degree of value whether or not each of these components are scaled to different values, for example, by multiplication or addition. Cumulative distribution fits this description. "The state of having identical cumulative distribution function or values".
Context
The definition of homogeneous strongly depends on the context used. For example, a composite material is made up of different individual materials, known as "constituents" of the material, but may be defined as a homogeneous material when assigned a function. For example, asphalt paves our roads, but is a composite material consisting of asphalt binder and mineral aggregate, and then laid down in layers and compacted.

Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.
Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain
Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

3DV 2021 Oral Presentation: In natural conversation and interaction, our hands often overlap or are in contact with each other. Due to the homogeneous appearance of hands, this makes estimating the 3D pose of interacting hands from images difficult. In this paper we demonstrate that self-similarity, and the resulting ambiguities in assigning pixel observations to the respective hands and their parts, is a major cause of the final 3D pose error. Motivated by this insight, we propose DIGIT, a novel method for estimating the 3D poses of two interacting hands from a single monocular image. The method consists of two interwoven branches that process the input imagery into a per-pixel semantic part segmentation mask and a visual feature volume. In contrast to prior work, we do not decouple the segmentation from the pose estimation stage, but rather leverage the per-pixel probabilities directly in the downstream pose estimation task. To do so, the part probabilities are merged with the visual features and processed via fully-convolutional layers. We experimentally show that the proposed approach achieves new state-of-the-art performance on the InterHand2.6M dataset. We provide detailed ablation studies to demonstrate the efficacy of our method and to provide insights into how the modelling of pixel ownership affects 3D hand pose estimation.

Symposium Artificial Intelligence and Ceremony of Awards. 21 and 22 October 2019.
Understanding language is a hard task for a computer even in the era of deep learning. In this talk I will advocate the importance of interdisciplinary work for multilingual Natural Language Understanding: I will present current state-of-the-art results attained by joining forces between computer scientists and (computational) linguists, in order to address the knowledge acquisition bottleneck and scale up key tasks in word- and sentence-level semantics which enable computers to understand what is written in a text. I will also showcase innovative multilingual solutions developed in my research group and at Babelscape, a Sapienza startup company I co-founded.

Mercury is the first planet from the Sun and the smallest in the Solar System. In English, it is named after the ancient Roman god Mercurius (Mercury), god of commerce and communication, and the messenger of the gods. Mercury is classified as a terrestrial planet, with roughly the same surface gravity as Mars. The surface of Mercury is heavily cratered, as a result of countless impact events that have accumulated over billions of years. Its largest crater, Caloris Planitia, has a diameter of 1,550 km (960 mi) and one-third the diameter of the planet (4,880 km or 3,030 mi). Similarly to the Earth's Moon, Mercury's surface displays an expansive rupes system generated from thrust faults and bright ray systems formed by impact event remnants.

Mercury's sidereal year (88.0 Earth days) and sidereal day (58.65 Earth days) are in a 3:2 ratio. This relationship is called spin–orbit resonance, and sidereal here means "relative to the stars". Consequently, one solar day (sunrise to sunrise) on Mercury lasts for around 176 Earth days: twice the planet's sidereal year. This means that one side of Mercury will remain in sunlight for one Mercurian year of 88 Earth days; while during the next orbit, that side will be in darkness all the time until the next sunrise after another 88 Earth days.
Combined with its high orbital eccentricity, the planet's surface has widely varying sunlight intensity and temperature, with the equatorial regions ranging from −170 °C (−270 °F) at night to 420 °C (790 °F) during sunlight. Due to the very small axial tilt, the planet's poles are permanently shadowed. This strongly suggests that water ice could be present in the craters. Above the planet's surface is an extremely tenuous exosphere and a faint magnetic field that is strong enough to deflect solar winds. Mercury has no natural satellite.
As of the early 2020s, many broad details of Mercury's geological history are still under investigation or pending data from space probes. Like other planets in the Solar System, Mercury was formed approximately 4.5 billion years ago. Its mantle is highly homogeneous, which suggests that Mercury had a magma ocean early in its history, like the Moon. According to current models, Mercury may have a solid silicate crust and mantle overlying a solid outer core, a deeper liquid core layer, and a solid inner core. There are many competing hypotheses about Mercury's origins and development, some of which incorporate collision with planetesimals and rock vaporization.

This simple example of causality is given as public service for those, like me, who struggle a little with the plethora of wikipedia disambiguation articles on the term, all full of mathematical formulae, discussion of things like causal dynamical triangulation, and sentences like:
"Causality should not be confused with Newton's second law, which is related to the conservation of momentum, and is a consequence of the spatial homogeneity of physical laws. The name causality suggests that all effects must have specific causes, which is a concept unrelated to the common use of causality in physics, and is violated in some mainstream interpretations of quantum mechanics."
Anyhoo, you can read through the whole thing here: https://en.wikipedia.org/wiki/Causality
... but don't worry if you don't understand it all, just refer back to this video if you get stuck on any part of the formal definition.
