Examples of Touch Points in the following topics:

  • Tangent Planes and Linear Approximations

    • The tangent plane to a surface at a given point is the plane that "just touches" the surface at that point.
    • The tangent line (or simply the tangent) to a plane curve at a given point is the straight line that "just touches" the curve at that point.
    • Similarly, the tangent plane to a surface at a given point is the plane that "just touches" the surface at that point.
    • The approximation works well as long as the point $(x,y,z) $ under consideration is close enough to $(x_0,y_0,z_0)$, where the tangent plane touches the surface.
    • The tangent plane to a surface at a given point is the plane that "just touches" the surface at that point.
  • The Derivative and Tangent Line Problem

    • The tangent line $t$ (or simply the tangent) to a plane curve at a given point is the straight line that "just touches" the curve at that point.
    • Informally, it is a line through a pair of infinitely close points on the curve.
    • To find the tangent line at the point $p = (a, f(a))$, consider another nearby point $q = (a + h, f(a + h))$ on the curve.
    • It barely touches the curve and shows the rate of change slope at the point.
    • Define a derivative as the slope of the tangent line to a point on a curve
  • Derivatives and Rates of Change

    • Historically, the primary motivation for the study of differentiation was the tangent line problem, which is the task of, for a given curve, finding the slope of the straight line that is tangent to that curve at a given point.
    • The word tangent comes from the Latin word tangens, which means touching.
    • Thus, to solve the tangent line problem, we need to find the slope of a line that is "touching" a given curve at a given point, or, in modern language, that has the same slope.
    • If $x$ and $y$ are real numbers, and if the graph of $y$ is plotted against $x$, the derivative measures the slope of this graph at each point.
    • Describe the derivative as the change in $y$ over the change in $x$ at each point on a graph
  • Spherical and Plane Waves

    • In 1678, he proposed that every point that a luminous disturbance touches becomes itself a source of a spherical wave; the sum of these secondary waves determines the form of the wave at any subsequent time.
    • Since the waves all come from one point source, the waves happen in a spherical pattern.
    • All the waves come from a single point source and are spherical .
    • Each point on the wave produces waves which interfere with each other either constructively or destructively.
    • When waves are produced from a point source, they are spherical waves.
  • Assessing CNS Disorders

    • An example of a specific type of neurological test is a monofilament test which evaluates fine touch by applying pressure to the skin with a set of nylon filaments.
    • Sensory system testing involves provoking sensations of fine touch, pain, and temperature.
    • Fine touch can be evaluated with a monofilament test, touching various dermatomes with a nylon monofilament to detect any subjective absence of touch perception.
  • Integration of Signals from Mechanoreceptors

    • The configuration of the different types of receptors working in concert in the human skin results in a very refined sense of touch .
    • The large mechanoreceptors (Pacinian corpuscles and Ruffini endings) are located in the lower layers and respond to deeper touch.
    • The subject reports if they feel one point or two points.
    • If the two points are felt as one point, it can be inferred that the two points are both in the receptive field of a single sensory receptor.
    • The points could then be moved closer and re-tested until the subject reports feeling only one point.
  • Plant Responses to Wind and Touch

    • Plants respond to wind and touch by changing their direction of growth, movement, and shape.
    • These are examples of how plants respond to touch or wind.
    • A thigmonastic response is a touch response independent of the direction of stimulus.
    • Tendrils of a redvine produce auxin in response to touching a support stick and then transfer the auxin to non-touching cells.
    • The non-touching cells elongate faster to curl around the support stick.
  • Sensory Areas

    • Sensory areas of the brain receive and process sensory information, including sight, touch, taste, smell, and hearing.
    • The five commonly recognized sensory modalities, including sight, hearing, taste, touch, and smell, are processed as follows:
    • Neighboring points in the primary visual cortex, for example, correspond to neighboring points in the retina.
  • Capacitors with Dielectrics

    • A dielectric partially opposes a capacitor's electric field but can increase capacitance and prevent the capacitor's plates from touching.
    • Eventually every material has a "dielectric breakdown point," at which the potential difference becomes too high for it to insulate, and it ionizes and permits the passage of current.
  • Animal Communication and Living in Groups

    • Animals communicate using signals, which can be chemical (pheromones), aural (sound), visual (courtship displays), or tactile (touch).
    • These signals are chemical (pheromones), aural (sound), visual (courtship and aggressive displays), or tactile (touch).
    • If at any point the display is performed incorrectly or a proper response is not given, the mating ritual is abandoned and the mating attempt will be unsuccessful.
    • Many animals, especially primates, communicate with other members in the group through touch.
    • Activities such as grooming, touching the shoulder or root of the tail, embracing, lip contact, and greeting ceremonies have all been observed in the Indian langur, an Old World monkey.
