Madelung notes other traditions suggesting that Hasan may have been poisoned by another wife, the daughter of Suhayl ibn Amr, or perhaps by one his servants and also cites the early historians ( Baladhuri, Waqidi, etc .).

* Hasan ibn ' Ali by Wilferd Madelung, In Encyclopædia Iranica

However Umar himself was characteristically guarded about his own creation, Dr. Wilferd Madelung in his book The Succession to Muhammad summarising Umar's contribution:

The Shi ’ a and Institute for Shia Ismaili Studies in London's Shia ' ism researcher Wilferd Madelung believe that Malik was poisoned by Muawiyah I.

This was approximately 12 years after the probable advent of great saphenous vein stripping in 1844 by Madelung.

The Shi ’ a and Wilferd Madelung believe that Malik was poisoned by Muawiyah I.

Madelung was Laudian Professor of Arabic at the University of Oxford from 1978 to 1998.

Wilferd Madelung has rejected the stance of indiscriminately dismissing everything not included in " early sources " and in this approach tendentious alone is no evidence for late origin.

A formalism has been worked out for those piezoelectric crystals, for which the polarization is of the crystal-field induced type, that allows for the calculation of piezoelectrical coefficients from electrostatic lattice constants or higher-order Madelung constants.

The quantum hydrodynamic equation is an equation in Bohmian mechanics, which, it turns out, has a mathematical relationship to classical fluid dynamics ( see Madelung equations ).

Madelung said of hadith: " Work with the narrative sources, both those that have been available to historians for a long time and others which have been published recently, made it plain that their wholesale rejection as late fiction is unjustified and that with without a judicious use of them, a much more reliable and accurate portrait of the period can be drawn than has been realized so far.

Around this time Erwin Madelung also developed a hydrodynamic version of Schrödinger's equation which is incorrectly considered as a basis for the density current derivation of the de Broglie – Bohm theory.

The positions shown in the table above correspond to the assumption that the Madelung rule will continue to hold for higher atomic numbers ; this assumption may or may not be true.

Pekka Pyykkö, for example, used computer modeling to calculate the positions of elements up to Z = 172, and found that several were displaced from the Madelung energy-ordering rule.

According to The Succession to Muhammad by Wilferd Madelung, Senior Research Fellow at the Institute for Ismaili Studies in London, Umar later described the event as a falta, a precipitate arrangement ( p. 30 ).

Pekka Pyykkö, for example, used computer modeling to calculate the positions of elements up to Z = 172, and found that several were displaced from the Madelung rule.

According to the Institute for Shia Ismaili Studies in London's Shia ' ism researcher Wilferd Madelung, only Uthman and Ali were willing to take the burden of the caliphate.

However, one recent publication, The Succession to Muhammad written by Institute for Ismaili Studies in London's researcher Wilfred Madelung, ex Laudian Professor of Arabic at the University of Oxford, examines the course of events from 632, and the death of Muhammad, through the rise of the Umayyads — and rehabilitates some of the Shia narratives.

On the right of Muhammad's household to succeed him, for instance, Madelung observes that:

** the Madelung constant for crystal structures held by ionic bonding

The Madelung constant being calculated for the NaCl ion labeled 0 in the expanding spheres method.

The Madelung constant shall allow for the calculation of the electric potential V < sub > i </ sub > of all ions of the lattice felt by the ion at position r < sub > i </ sub >

For example, for the ionic crystal NaCl, there arise two Madelung constants – one for Na and another for Cl.

This graph demonstrates the non-convergence of the expanding spheres method for calculating the Madelung Constant for NaCl as compared to the expanding cubes method, which is convergent.

Contemporary Western scholars of hadith include: Herbert Berg, Fred M. Donner and Wilferd Madelung.

Madelung has immersed himself in the hadith literature and has made his own selection and evaluation of tradition.

The electrostatic potential can be expressed in terms of the inter-ionic separation and a constant ( Madelung constant ) that takes account of the geometry of the crystal.

This configuration agrees with the Madelung energy ordering rule, which predicts that 4s is filled before 3d.

The Madelung equations, being quantum Euler equations ( fluid dynamics ), differ philosophically from the de Broglie – Bohm mechanics and are the basis of the hydrodynamic interpretation of quantum mechanics.

This period is known to have a large number of exceptions to the Madelung rule.

All period 2 elements completely obey the Madelung rule ; in period 2s, lithium and beryllium fill the 2s subshell, and boron, carbon, nitrogen, oxygen, fluorine, and neon fill the 2p subshell.

Benign symmetric lipomatosis ( Madelung disease ) is another condition involving lipomatosis.

In quantum chemistry they arise as solutions to chemical kinetic systems, in which case they are derived from the Schrödinger equation by way of Madelung equations.

According to Wilferd Madelung, Muhammad loved them and declared them as his Ahl al-Bayt very frequently.

Examples of intramolecular reactions are the Smiles rearrangement, the Dieckmann condensation and the Madelung synthesis.

In 1935, Georg Hans Madelung, a German engineer, professor, and aircraft designer, showed that a vehicle does not need a long tapered tail at high speeds.
