Timoshenko beam theory print that page

The Timoshenko beam theory was developed by Ukrainian-born scientist Stephen Timoshenko in the beginning of the 20th century [ 1 ] [ 2 ] . The model takes into account shear deformation and rotational inertia effects, making it suitable for describing the behaviour of short beams, sandwich | 2011/3/23 9:36:35

Emission theory print that page

The name most often associated with emission theory is Isaac Newton . In his Corpuscular theory Newton visualized light "corpuscles" being thrown off from hot bodies at a nominal speed of c with respect to the emitting object, and obeying the usual laws of Newtonian mechanics, and we then | 2011/8/11 10:56:02

Wave–particle duality print that page


Einstein , Louis de Broglie , Arthur Compton , Niels Bohr , and many others, current scientific theory holds that all particles also have a wave nature (and vice versa). [ 1 ] This phenomenon has been verified not only for elementary particles, but also for compound particles like atoms

Local hidden variable theory print that page

In quantum mechanics , a local hidden variable theory is one in which distant events are assumed to have no instantaneous (or at least faster-than-light ) effect on local ones. According to the quantum entanglement theory of quantum mechanics, on the other hand, distant events may under | 2010/10/1 11:43:29

the titles of several paintings (Bockemuhl, 1991 [ 1 ] ). Wassily Kandinsky considered Goethe's theory "one of the most important works." [ 2 ] Although Goethe's work was never well received by physicists, a number of philosophers and physicists have been known to have concerned themselves

Introduction to quantum mechanics print that page


and the spectral intensities of all forms of electromagnetic radiation . But quantum mechanics theory ordains that the more closely one pins down one measure (such as the position of a particle), the less precise another measurement pertaining to the same particle (such as its momentum

Introduction to general relativity print that page


standard Big Bang model of cosmology . Although general relativity is not the only relativistic theory of gravity, it is the simplest such theory that is consistent with the experimental data. Nevertheless, a number of open questions remain, the most fundamental of which is how general

Euler–Bernoulli beam equation print that page


Additional analysis tools have been developed such as plate theory and finite element analysis , but the simplicity of beam theory makes it an important tool in the sciences, especially structural and mechanical engineering . Contents 1 History 2 Static beam equation 3 Dynamic

Emission theory (vision) print that page

interaction between rays from the eyes and rays from a source such as the sun. Around 400 BCE, emission theory was held by Plato . [2] . [ dead link ] In about 300 BCE, Euclid wrote Optica , in which he studied the properties of light. Euclid postulated that light travelled in straight | 2010/9/25 6:54:56
