From Wikipedia:
"Mathematics is often defined as the study of topics such as quantity , structure , space , and change . In the formalist view, it is the investigation of axiomatically defined abstract structures using logic and mathematical notation .
Practical mathematics, in nearly every society, is used for such purposes as accounting , measuring land, or predicting astronomical events. Mathematical discovery or research often involves discovering and cataloging patterns, without regard for application. Other fields of knowledge, such as the natural sciences , engineering , economics , or medicine , make use of many new mathematical discoveries.
The word "mathematics" comes from the Greek μ?θημα ( math?ma ) meaning "science, knowledge, or learning" and μαθηματικ?? ( math?matikos ) meaning "fond of learning". It is often abbreviated maths in Commonwealth English and math in North American English . "
"Physics (from the Greek, φυσικ?? (physikos), "natural", and φ?σι? (physis), "nature") is the science of the natural world dealing with the fundamental constituents of the universe, the forces they exert on one another, and the results produced by these forces. Sometimes in modern physics a more sophisticated approach is taken that incorporates elements of the three areas listed above; it relates to the laws of symmetry and conservation, such as those pertaining to energy, momentum, charge, and parity. [1] Physicists study a wide range of physical phenomena spanning all length scales: from the subatomic particles from which all ordinary (i.e., baryonic) matter is made (particle physics) to the behavior of the material Universe as a whole (cosmology)
Physics discoveries find applications throughout the other natural sciences, since it studies the basic constituents of the natural world. Some of the phenomena studied in physics, such as the conservation of energy, are common to all material systems. These are often referred to as laws of physics. Physics is sometimes said to be the "fundamental science", because each of the other natural sciences (biology, chemistry, geology, etc.) deals with particular types of material systems that obey the laws of physics. For example, chemistry is the science of molecules and the chemicals that they form in the bulk. The properties of a chemical are determined by the properties of the underlying molecules, which can be described by areas of physics such as quantum mechanics (called in this case quantum chemistry), thermodynamics, and electromagnetism.
Physics is closely related to mathematics, which provides the logical framework where physical laws can be precisely formulated and their predictions quantified. Physical theories are almost invariably expressed using mathematical relations. The difference between physics and mathematics is that physics is ultimately concerned with descriptions of the material world, whereas mathematics is concerned with abstract patterns that need not have any bearing on it. The distinction, however, is not always clear-cut. There is a large area of research intermediate between physics and mathematics, known as mathematical physics, devoted to developing the mathematical structure of physical theories.
While physics has a remarkably broad purview, it attempts only to describe those aspects of the world that can be dealt with by the scientific method. It is not concerned with issues that cannot be verified even in principle, such as those studied in metaphysics"
Sensation
7 human senses of sight , taste , smell , touch , hearing ,balance and motion.
A "sensation"that might lead to that statement could include the excitation of cone cells in the retina, spatially varying in the proportion of "blue" and "green" cone excitation due to portions of the wall receiving different proportions of yellowish artificial and bluish sky-light; it is common for these variations to be compensated for, within the brain, so that the non-uniform sensation yields a perception of uniform color.
In the West, the human body's senses are divided into seven: visual, auditory, gustatory, olfactory, cutaneous, kinesthetic, vestibular, organic. The ways in which these senses are divided from one another in concept, and combined in varying ratios in perceiving the world, differs based on individual physiology, social and cultural context, and physical surroundings. The whole sensory system, including both physical sensation and interpretation (or cognition) of information from the senses, is referred to as a sensorium
Perception
From Wikipedia:
In psychology and the cognitive sciences, perception is the process of acquiring, interpreting, selecting, and organizing sensory information. Methods of studying perception range from essentially biological or physiological approaches, through psychological approaches to the often abstract 'thought-experiments' of mental philosophy.
Perception is one of the oldest fields within scientific psychology, and there are correspondingly many theories about its underlying processes. The oldest quantitative law in psychology is the Weber-Fechner law, which quantifies the relationship between the intensity of physical stimuli and their perceptual effects. It was the study of perception that gave rise to the Gestalt school of psychology, with its emphasis on holistic
