locating anti matter by 3 formats

1)

the specific heat release of a electron

2)

the latent heat of a positive electron

3)

the trace locations of waveformats that generate the 3 rd value  missing electron by the traces of triangulated computations of the 3 rd value electron as the anti matter locator of the value of heat needed to displace 3 electrons simultaneously in a 1 positive electron boost.

Linear elasticity is the mathematical study of how solid objects deform and become internally stressed due to prescribed loading conditions. Linear elasticity relies upon the continuum hypothesis and is applicable at macroscopic (and sometimes microscopic) length scales. Linear elasticity is a simplification of the more general nonlinear theory of elasticity and is a branch of continuum mechanics. The fundamental “linearizing” assumptions of linear elasticity are: infinitesimal strains or “small” deformations (or strains) and linear relationships between the components of stress and strain. In addition linear elasticity is only valid for stress states that do not produce yielding. These assumptions are reasonable for many engineering materials and engineering design scenarios. Linear elasticity is therefore used extensively in structural analysisand engineering design, often through the aid of finite element analysis.

Elastodynamics — the wave equation

Elastodynamics is the study of linear elasticity which include variation in time. The most common case considered in elastodynamics is the wave equation. This section will discuss only the isotropic homogeneous case.

If the material is homogeneous (i.e. the elasticity tensor is constant throughout the material), the three basic equations can be combined to form the elastodynamic equation:

 \mu u_{i,jj}+(\mu+\lambda)u_{j,ij}+F_i=\rho\partial_{tt}u_i \,\,\,\,\,\,\,\,\mathrm{or}\,\,\,\,\,\,\,\, \mu\nabla^2\mathbf{u}+(\mu+\lambda)\nabla(\nabla\cdot\mathbf{u})+\mathbf{F}=\rho\frac{\partial^2\mathbf{u}}{\partial t^2}. \,\!

From the elastodynamic equation one gets the wave equation

 (\delta_{kl} \partial_{tt}-A_{kl}[\nabla])\, u_l  = \frac{1}{\rho} f_k\,\!

where

 A_{kl}[\nabla]=\frac{1}{\rho} \, \partial_i \, C_{iklj} \, \partial_j\,\!

is the acoustic differential operator, and  \delta_{kl}\,\! is Kronecker delta.

In isotropic media, the elasticity tensor has the form

 C_{ijkl} =  K \, \delta_{ij}\, \delta_{kl} +\mu\, (\delta_{ik}\delta_{jl}+\delta_{il}\delta_{jk}-\frac{2}{3}\, \delta_{ij}\,\delta_{kl})\,\!

where K\,\! is the bulk modulus (or incompressibility), and \mu\,\! is the shear modulus (or rigidity), two elastic moduli. If the material is homogeneous (i.e. the elasticity tensor is constant throughout the material), the acoustic operator becomes:

A_{ij}[\nabla]=\alpha^2 \partial_i\partial_j+\beta^2(\partial_m\partial_m\delta_{ij}-\partial_i\partial_j)\,\!

and the acoustic algebraic operator becomes

A_{ij}[\mathbf{k}]=\alpha^2 k_ik_j+\beta^2(k_mk_m\delta_{ij}-k_ik_j)\,\!

where

 \alpha^2=\left(K+\frac{4}{3}\mu\right)/\rho \qquad \beta^2=\mu/\rho\,\!

are the eigenvalues of A[\hat{\mathbf{k}}]\,\! with eigenvectors \hat{\mathbf{u}}\,\! parallel and orthogonal to the propagation direction \hat{\mathbf{k}}\,\!, respectively. In the seismological literature, the corresponding plane waves are called P-waves and S-waves (see Seismic wave).

podium (plural podia) is a platform that is used to raise something to a short distance above its surroundings. In architecture a building can rest on a large podium. Podia can also be used to raise people, for instance the conductor of an orchestra stands on a podium as do many public speakers. Podium has also come to mean the object a speaker stands behind and sets papers or books upon[1] even when it is at floor level, though the traditional term for that item is lectern. The terms are not identical; one typically stands on a podium, but one typically stands behind a lectern.

In sports, a type of podium is used to honor the top three competitors in events such as the Olympics. In the Olympics a three level podium is used, the highest level in the centre holds the gold medalist, to their right is a somewhat lower one for the silver medalist. To the left of the gold medalist is an even lower platform for the bronze medalist. In many sports, results in the top three of a competition are often referred to as podiums, or podium finishes. In some individual sports, “podiums” is an official statistic, referring to the number of top three results an athlete has achieved over the course of a season or career.

In incompressible fluid dynamics dynamic pressure (indicated with q, or Q, and sometimes called velocity pressure or impact pressure) is the quantity defined by:[1]

q = \tfrac12\, \rho\, v^{2},

where (using SI units):

q\; = dynamic pressure in pascals,
\rho\; = fluid density in kg/m3 (e.g. density of air),
v\; = fluid velocity in m/s.

Physical meaning

Dynamic pressure is closely related to the kinetic energy of a fluid particle, since both quantities are proportional to the particle’s mass (through the density, in the case of dynamic pressure) and square of the velocity. Dynamic pressure is in fact one of the terms of Bernoulli’s equation, which is essentially an equation of energy conservation for a fluid in motion. The dynamic pressure is equal to the difference between the stagnation pressure and the static pressure.[1]

Another important aspect of dynamic pressure is that, as dimensional analysis shows, the aerodynamic stress (i.e. stress within a structure subject to aerodynamic forces) experienced by an aircraft traveling at speed v is proportional to the air density and square of v, i.e. proportional to q. Therefore, by looking at the variation of q during flight, it is possible to determine how the stress will vary and in particular when it will reach its maximum value. The point of maximum aerodynamic load is often referred to as max Q and it is a critical parameter, for example, for spacecraft during launch.

[edit]Uses

The dynamic pressure, along with the static pressure and the pressure due to elevation, is used in Bernoulli’s principle as an energy balance on a closed system. The three terms are used to define the state of a closed system of an incompressible, constant-density fluid.

If we were to divide the dynamic pressure by fluid density, the result is called velocity head, which is used in head equations like the one used for hydraulic head.

[edit]Compressible flow

Many authors define dynamic pressure only for incompressible flows. (For compressible flows, these authors use the concept of impact pressure.) However, some British authors extend their definition of dynamic pressure to include compressible flows.[2][3]

If the fluid in question can be considered an ideal gas (which is generally the case for air), the dynamic pressure can be expressed as a function of fluid pressure and Mach number.

By applying the ideal gas law:[4]

p = \rho\, R\, T,\,

the definition of speed of sound a and of Mach number M:[5]

a = \sqrt{\gamma\, R\, T} and  M = \frac{v}{a},

dynamic pressure can be rewritten as:[6]

q = \tfrac12\, \gamma\, p_{s}\, M^{2},

where (using SI units):

p_{s}\; = static pressure in pascals,
\rho\; = density in kg·m−3, or kg/kL
R\; specific gas constant (287.05 J·kg−1·K−1 for air),
T\; absolute temperature in kelvins,
M\; = Mach number (non-dimensional),
\gamma\; ratio of specific heats (non-dimensional) (1.4 for air at sea level conditions),
v\; = fluid velocity in m·s−1,
a\; = speed of sound in m·s−1

Hypersurfaces in n-dimensional space

The definition of a normal to a surface in three-dimensional space can be extended to n − 1-dimensional hypersurfaces in a n-dimensional space. A hypersurface may be locally defined implicitly as the set of points \scriptstyle(x_1, x_2, \ldots, x_n) satisfying an equation \scriptstyle F(x_1, x_2, \ldots x_n) = 0, where F is a given scalar function. If F is continuously differentiable, then the hypersurface obtained is a differentiable manifold, and its hypersurface normal can be obtained from the gradient of F, in the case it is not null, by the following formula

\nabla F(x_1, x_2, \ldots, x_n) = \left( \tfrac{\partial F}{\partial x_1}, \tfrac{\partial F}{\partial x_2}, \ldots, \tfrac{\partial F}{\partial x_n} \right)

The solid angleΩ, is the two-dimensional angle in three-dimensional space that an object subtends at a point. It is a measure of how large that object appears to an observer looking from that point. A small object nearby may subtend the same solid angle as a larger object farther away. An object’s solid angle is equal to the area of the segment of unit sphere (centered at the vertex of the angle) restricted by the object (this definition works in any dimension, including 1D and 2D). A solid angle equals the area of a segment of unit sphere in the same way a planar angle equals the length of an arc of unit circle.

The units of solid angle can be called steradian (abbreviated “sr”) according to SI. From the point of view of mathematics and physics solid angle is dimensionless and has no units, thus “sr” might be skipped in scientific texts. The solid angle of a sphere measured from a point in its interior is 4π sr, and the solid angle subtended at the center of a cube by one of its faces is one-sixth of that, or 2π/3 sr. Solid angles can also be measured in square degrees (1 sr = (180/π)2 square degree) or in fractions of the sphere (i.e., fractional area), 1 sr = 1/4π fractional area.

One way to determine the fractional area subtended by a spherical surface is to divide the area of that surface by the entire surface area of the sphere. The fractional area can then be converted to steradian or square degree measurements by the following formulae:

  1. To obtain the solid angle in steradians, multiply the fractional area by 4π.
  2. To obtain the solid angle in square degrees, multiply the fractional area by 4π × (180/π)2, which is equal to 129600/π.

The solid angle for an arbitrary oriented surface S subtended at a point P is equal to the solid angle of the projection of the surface S to the unit sphere with center P, which can be calculated as the surface integral:

\Omega = \iint_S \frac { \vec{r} \cdot \hat{n} dS }{r^3}.[1]

where  \vec{r} is the vector position of an infinitesimal area of surface  \, dS with respect to point P and where  \hat{n} represents the unit vector normal to  \, dS . Even if the projection on the unit sphere to the surface S is not isomorphic, the multiple folds are correctly considered according to the surface orientation described by the sign of the scalar product \vec{r} \cdot \hat{n}.

The critical angle is the angle of incidence above which total internal reflection occurs. The angle of incidence is measured with respect to the normal at the refractive boundary. The critical angle θc is given by:

\theta_c = \arcsin \left( \frac{n_2}{n_1} \right),

where n2 is the refractive index of the less optically dense medium, and n1 is the refractive index of the more optically dense medium.

If the incident ray is precisely at the critical angle, the refracted ray is tangent to the boundary at the point of incidence. If for example, visible light were traveling through acrylic glass (with an index of refraction of 1.50) into air (with an index of refraction of 1.00). The calculation would give the critical angle for light from acrylic into air, which is

\theta _{c}=\arcsin \left( 1.00/1.50 \right)=41.8{}^\circ .

Light incident on the border with an angle less than 41.8° would be partially transmitted, while light incident on the border at larger angles with respect to normal would be totally internally reflected.

If the fraction: \frac{n_2}{n_1} is greater than 1, then arcsine is not defined–meaning that total internal reflection does not occur even at very shallow or grazing incident angles.

So the critical angle is only defined when \frac{n_2}{n_1} is less than 1.

Litmus is a watersoluble mixture of different dyes extracted from lichens, especially Roccella tinctoria. It is often absorbed onto filter paper to produce one of the oldest forms of pH indicator, used to test materials for acidity. Blue litmus paper turns red under acidic conditions and red litmus paper turns blueunder basic (i.e. alkaline) conditions with the color change occurring over the pH range 4.5-8.3 at 25 °C. Neutral litmus paper is purple in color.[1] Litmus can also be prepared as an aqueous solution that functions similarly. Under acidic conditions the solution is red, and under basic conditions the solution is blue.

The litmus mixture has the CAS number 1393-92-6 and contains 10 to 15 different dyes. Most of the chemical components of litmus are likely to be the same as of the related mixture known as orcein, but in different proportions. In contrast with orcein, the principal constituent of litmus has average molecular weight of 3300.[2] Acid-base indicators on litmus owe their properties to a 7-hydroxyphenoxazone chromophore.[3] Some fractions of litmus were given specific names including erythrolitmin (or erythrolein), azolitmin, spaniolitmin, leucoorcein and leucazolitmin. Azolitmin shows nearly the same effect as litmus.[4]
