Spinning Top

SummaryThis paper has been compiled because of the applicability of the treatment of the stability of the motion of the common spinning top to the problem of the whirling of rotating shafts, carrying loads of appreciable moments of inertia. This problem is assuming renewed interest and importance, especially in the drives of contra-propeller systems and the more recent high speed prime movers.

Abstract The geometries and vibrational frequency of the stable AuN clusters with N = 21 to 25 are presented through the global structure re-optimization study. The finite-differentiation method has been implemented within the density-functionaltight-binding (DFTB) approach. The effect of the range of interatomic forces was calculated and the desired set of system eigenfrequencies (3N-6) is obtained by diagonalization of the symmetric positive semidefinite Hessian matrix. We have observed the vibrational spectral ranges of between 2.88 and 328.25 cm-1 Δ E=0, and even the minute details of the very lower frequencies were occupied in some clusters at the beginning of NVM itself which comes even below the scale of Far Infrared FIR, IR-C 200-10 cm-1. Significantly, some of the clusters spectrums are with double state degeneracy and the rest of them are having single state degeneracy. Nevertheless, our investigation has revealed that the vibrational spectrum strongly depends upon the size, shape, and structure, as well as, stretching and bending vibrations of the atoms.

Cobb’s ‘Emotional Journey’: From Guilt to Redemption

This chapter investigates the development of Cobb's character in Christopher Nolan's Inception (2010). It reveals how Cobb (Leonardo DiCaprio) progresses from a haunted, guilt-ridden man through the major part of the film to becoming a man who has come to terms with what he has done and who has redeemed himself morally. The first hint that there is some unresolved emotional conflict in Cobb's mind comes with the first appearance of Mal. The audience later learns that she is an image created from his own unconscious, and by their nature such images, being inaccessible to conscious control, should be treated with suspicion. One can guess that some kind of guilt complex is causing Cobb to project this image of Mal. At the end of the film, Cobb has finally worked through and overcome his guilt, rid himself of his obsession with Mal, by recognising her as a shade, a poor imitation. The final ambiguous image in the film of the spinning top and Cobb's reunion with his children can be interpreted as implying that maybe it does not matter whether the scene is real or not. As Cobb realised and tried to convince Mal: it is the reality of the experience which is important.
