A logarithmic spiral, equiangular spiral, or growth spiral is a self-similar spiral curve that often appears in nature. The first to describe a logarithmic spiral was Albrecht Dürer who called it an eternal line. More than a century later, the curve was discussed by Descartes, and later extensively investigated by Jacob Bernoulli, who called it Spira mirabilis, the marvelous spiral. The logarithmic spiral can be distinguished from the Archimedean spiral by the fact that the distances. The equiangular spiral (also known as logarithmic spiral, Bernoulli spiral, and logistique) describes a family of spirals. It is defined as a monotonic curve that cuts all radii vectors at a constant angle

2 James Bernoulli poses a problem of elasticity-1694 The ﬁrst appearance of the Euler spiral is as a problem of elasticity, posed by James Bernoulli in the same 1694 publication as his solution to a related problem, that of the elastica. The elastica is the shape deﬁned by an initially straight band of thin elastic material (such as sprin Sequence S is called the Bernoulli spiral lattice (Fig. 2a). In the phyllotaxis theory, 1/r is called the plastochrone ratio and h is called the divergence angle. In this paper, we call h/2p the divergence.

Logarithmische Spirale. Die logarithmische Spirale ist eine Spirale, die mit jeder Umdrehung den Abstand von ihrem Mittelpunkt, dem Pol, um den gleichen Faktor vergrößert. In umgekehrter Drehrichtung schlingt sich die Kurve mit abnehmendem Radius immer enger um den Pol. Jede Gerade durch den Pol schneidet die logarithmische Spirale stets. Jacob Bernoulli also discovered a general method to determine evolutes of a curve as the envelope of its circles of curvature. He also investigated caustic curves and in particular he studied these associated curves of the parabola, the logarithmic spiral and epicycloids around 1692 Spiral Curve: For a spiral curve, the rate of change of radius is uniform throughout the length.

The logarithmic spiral was first studied by Descartes in 1638 and Jakob Bernoulli. Bernoulli was so fascinated by the spiral that he had one engraved on his tombstone (although the engraver did not draw it true to form). Torricelli worked on it independently and found the length of the curve (MacTutor Archive).

The logarithmic spiral is a spiral whose polar equation is given by r=ae^(btheta), (1) where r is the distance from the origin, theta is the angle from the x-axis, and a and b are arbitrary constants. The logarithmic spiral is also known as the growth spiral, equiangular spiral, and spira mirabilis. It can be expressed parametrically as x = rcostheta=acosthetae^(btheta) (2) y = rsintheta.

Bernoulli Equation The Bernoulli equation is the most widely used equation in fluid mechanics, and assumes frictionless flow with no work or heat transfer. However, flow may or may not be irrotational. When flow is irrotational it reduces nicely using the potential function in place of the velocity vector

According to the Bernoulli's principle when area available for the fluid to flow decrease then flow velocity of the fluid increase and at the mean while time the fluid pressure or the fluid potential energy decreases (R.K. Bansal (n.d)). This principle was name after the Daniel Bernoulli who first writes this principle in book named Hydrodynamic En logaritmisk spiral är en speciell form av spiralkurva som ofta förekommer i naturen, från olika slag av levande organismer; så som blommor, skaldjur och snäckor till hur galaxer är formade och olika vädersystem..
