History. Differential equations first came into existence with the invention of calculus by Newton and Leibniz.In Chapter 2 of his 1671 work Methodus fluxionum et Serierum Infinitarum, Isaac Newton listed three kinds of differential equations: = = (,) + = In all these cases, y is an unknown function of x (or of x 1 and x 2), and f is a given function. He solves these examples and others …

What type of subject is physics?. Physics can be described as all of the following: An academic discipline – one with academic departments, curricula and degrees; national and international societies; and specialized journals.; A scientific field (a branch of science) – widely recognized category of specialized expertise within science, and typically embodies its own terminology …

List of 3D inertia tensors. This list of moment of inertia tensors is given for principal axes of each object.. To obtain the scalar moments of inertia I above, the tensor moment of inertia I is projected along some axis defined by a unit vector n according to the formula: , where the dots indicate tensor contraction and the Einstein summation convention is used. In the above table, n would …

An ebook (short for electronic book), also known as an e-book or eBook, is a book publication made available in digital form, consisting of text, images, or both, readable on the flat-panel display of computers or other electronic devices. Although sometimes defined as "an electronic version of a printed book", some e-books exist without a printed equivalent. E-books can be …

Thermodynamics is a branch of physics that deals with heat, work, and temperature, and their relation to energy, entropy, and the physical properties of matter and radiation.The behavior of these quantities is governed by the four laws of thermodynamics which convey a quantitative description using measurable macroscopic physical quantities, but may be explained in terms …

In mathematics, particularly in linear algebra, matrix multiplication is a binary operation that produces a matrix from two matrices. For matrix multiplication, the number of columns in the first matrix must be equal to the number of rows in the second matrix. The resulting matrix, known as the matrix product, has the number of rows of the first and the number of columns of the …

For example, in Enrico Rodrigo's The Physics of Stargates, a wormhole is defined informally as: a region of spacetime containing a "world tube" (the time evolution of a closed surface) that cannot be continuously deformed (shrunk) to a world line (the time evolution ... and fully traversable in both directions. The drainhole is a solution manifold of Einstein's field equations …

Graph. The graph of = is upward-sloping, and increases faster as x increases. The graph always lies above the x-axis, but becomes arbitrarily close to it for large negative x; thus, the x-axis is a horizontal asymptote.The equation = means that the slope of the tangent to the graph at each point is equal to its y-coordinate at that point.. Relation to more general exponential functions. …

In classical physics and general chemistry, matter is any substance that has mass and takes up space by having volume. All everyday objects that can be touched are ultimately composed of atoms, which are made up of interacting subatomic particles, and in everyday as well as scientific usage, "matter" generally includes atoms and anything made up of them, and any particles (or …
