The cat (Felis catus, or Felis silvestris catus, literally "woodland cat"), often referred to as the domestic cat to distinguish from other felids and felines, is a small, typically furry, carnivorous mammal. It is often called house cat when kept as indoor pet or feral/feral domestic cat when wild. It is often valued by humans for companionship and for its ability to hunt vermin. There are more than seventy cat breeds recognized by various cat registries.
Cats are similar in anatomy to the other felids, with a strong flexible body, quick reflexes, sharp teeth and retractable claws adapted to killing small prey. Cat senses fit a crepuscular and predatory ecological niche. Cats can hear sounds too faint or too high in frequency for human ears, such as those made by mice and other small animals. They can see in near darkness. Like most other mammals, cats have poorer color vision and a better sense of smell than humans. Cats, despite being solitary hunters, are a social species, and cat communication includes the use of a variety of vocalizations (mewing, purring, trilling, hissing, growling and grunting) as well as cat pheromones and types of cat-specific body language.

The domestic dog
is a mammal
in the canine
family of the Order Carnivora
. Based on genetic evidence
, dogs began from a single domestication
of a now-extinct wolf-like canid in Western Europe 27 to 40 thousand years ago. Since this time, the dog has developed into hundreds of breeds with a great degree of variation in height and weight, coat color and texture, anatomical details and behavior. Dogs fill a variety of roles in human society and are often trained as working dogs
. For dogs that do not have traditional jobs, a wide range of dog sports
provide the opportunity to exhibit their natural skills. In many countries the most common, and perhaps most important, role of dogs is as companions
. Dogs have lived with and worked with humans in so many roles that their loyalty has earned them the sobriquet
"man's best friend."

is the process of facilitating learning
, or the acquisition of knowledge
, and habits.
Educational methods include storytelling
, and directed research
. Education frequently takes place under the guidance of educators, but learners may also educate themselves
. Education can take place in formal
settings and any experience
that has a formative effect on the way one thinks, feels, or acts may be considered educational. The methodology of teaching is called pedagogy
Formal education is commonly divided formally into such stages as preschool or kindergarten, primary school, secondary school and then college, university, or apprenticeship.
A right to education has been recognized by some governments and the United Nations. In most regions, education is compulsory up to a certain age.

The 'philosophy of science' is the branch of philosophy that studies the philosophical assumptions, foundations, and implications of science, including the formal sciences, natural sciences, and social sciences. In this respect, the philosophy of science is closely related to epistemology and philosophy of language. Note that issues of scientific ethics are not usually considered to be part of the philosophy of science; they are studied in such fields as bioethics and science studies.
In particular, the philosophy of science considers the following topics: the character and the development of concepts and terms, propositions and hypotheses, arguments and conclusions as they function in science.The manner in which science explains natural phenomena and predicts natural occurrences. The types of reasoning that are used to arrive at scientific conclusions; the formulation, scope, and limits of scientific method. The means that should be used for determining when scientific information has adequate objective support, and the implications of scientific methods and models, along with the technology that arises from scientific knowledge for the larger society.
Philosophy of science – Wikipedia book
is an academic and applied discipline
that involves the scientific study
of mental functions
. Psychology has the immediate goal of understanding individuals and groups by both establishing general principles and researching specific cases, and by many accounts it ultimately aims to benefit society. In this field, a professional practitioner
or researcher is called a psychologist
and can be classified as a social
, or cognitive scientist
. Psychologists attempt to understand the role of mental functions in individual and social behavior
, while also exploring the physiological
processes that underlie cognitive functions and behaviors.
Psychologists explore concepts such as perception, cognition, attention, emotion, phenomenology, motivation, brain functioning, personality, behavior, and interpersonal relationships, including psychological resilience, family resilience, and other areas. Psychologists of diverse orientations also consider the unconscious mind. Psychologists employ empirical methods to infer causal and correlational relationships between psychosocial variables. In addition, or in opposition, to employing empirical and deductive methods, some—especially clinical and counseling psychologists—at times rely upon symbolic interpretation and other inductive techniques. Psychology has been described as a "hub science", with psychological findings linking to research and perspectives from the social sciences, natural sciences, medicine, and the humanities, such as philosophy.

Science (from Latin scientia, meaning "knowledge") is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
The earliest roots of science can be traced to Ancient Egypt and Mesopotamia in around 3500 to 3000 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to explain events of the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages but was preserved in the Muslim world during the Islamic Golden Age. The recovery and assimilation of Greek works and Islamic inquiries into Western Europe from the 10th to 13th century revived natural philosophy, which was later transformed by the Scientific Revolution that began in the 16th century as new ideas and discoveries departed from previous Greek conceptions and traditions. The scientific method soon played a greater role in knowledge creation and it was not until the 19th century that many of the institutional and professional features of science began to take shape.
Modern science is typically divided into three major branches that consist of the natural sciences (e.g., biology, chemistry, and physics), which study nature in the broadest sense; the social sciences (e.g., economics, psychology, and sociology), which study individuals and societies; and the formal sciences (e.g., logic, mathematics, and theoretical computer science), which study abstract concepts. There is disagreement, however, on whether the formal sciences actually constitute a science as they do not rely on empirical evidence. Disciplines that utilize existing scientific knowledge for practical purposes, such as engineering and medicine, are described as applied sciences.
Science is based on research, which is commonly conducted in academic and research institutions as well as in government agencies and companies. The practical impact of scientific research has led to the emergence of science policies that seek to influence the scientific enterprise by prioritizing the development of commercial products, armaments, health care, and environmental protection.

|Scheme of sustainable development:|
at the confluence of three preoccupations. Clickable.
Sustainable development has been defined as balancing the fulfillment of human needs with the protection of the natural environment so that these needs can be met not only in the present, but in the indefinite future. The term was used by the Brundtland Commission which coined what has become the most often-quoted definition of sustainable development as development that "meets the needs of the present without compromising the ability of future generations to meet their own needs."
The field of sustainable development can be conceptually divided into four general dimensions: social, economic, environmental and institutional. The first three dimensions address key principles of sustainability, while the final dimension addresses key institutional policy and capacity issues.

may be defined as a cultural system
of designated behaviors
and practices, worldviews
, sanctified places
, or organizations
, that relates humanity to supernatural
, or spiritual
elements. However, there is no scholarly consensus over what precisely constitutes a religion.
Different religions may or may not contain various elements ranging from the divine, sacred things, faith, a supernatural being or supernatural beings or "some sort of ultimacy and transcendence that will provide norms and power for the rest of life". Religious practices may include rituals, sermons, commemoration or veneration (of deities), sacrifices, festivals, feasts, trances, initiations, funerary services, matrimonial services, meditation, prayer, music, art, dance, public service, or other aspects of human culture. Religions have sacred histories and narratives, which may be preserved in sacred scriptures, and symbols and holy places, that aim mostly to give a meaning to life. Religions may contain symbolic stories, which are sometimes said by followers to be true, that have the side purpose of explaining the origin of life, the universe, and other things. Traditionally, faith, in addition to reason, has been considered a source of religious beliefs.
There are an estimated 10,000 distinct religions worldwide, but about 84% of the world's population is affiliated with one of the five largest religion groups, namely Christianity, Islam, Hinduism, Buddhism or forms of folk religion. The religiously unaffiliated demographic includes those who do not identify with any particular religion, atheists and agnostics. While the religiously unaffiliated have grown globally, many of the religiously unaffiliated still have various religious beliefs.
The study of religion encompasses a wide variety of academic disciplines, including theology, comparative religion and social scientific studies. Theories of religion offer various explanations for the origins and workings of religion, including the ontological foundations of religious being and belief.
