This is a survey on Diophantine equations, with the purpose being to give the flavour of some known results on the subject and to describe a few open problems. We will come across Fermat’s last theorem and its proof by Andrew Wiles using the modularity of elliptic curves, and we will exhibit other Diophantine equations which were solved à la Wiles. We will exhibit many families of Thue equation...

Fluoresing photography has become a prominent branch in opthalmology. During the last few years, it gives us dynamic infor-of circulation of the EYE and its pathologieal disorders.By passing the fluoresein through the retinal and choroidal vessels we are able to record the different typesand stages of disease which these are not exactly diagno-sed by ophthalmoscopy and founds photography.By flu...

Simultaneously with inventing the modern relativistic formalism of quantum electrodynamics, Feynman presented also a first-quantized representation of QED in terms of worldline path integrals. Although this alternative formulation has been studied over the years by many authors, only during the last fifteen years it has acquired some popularity as a computational tool. I will shortly review her...

Hepatoportal sclerosis or idiopathic portal hypertension has a worldwide distribution with prevalence in developing and temperate countries. Of 64 patients with this disease seen during a twelve year period, 36 underwent splenectomy or a shunt procedure. The indications for surgical intervention were severe hypersplenism and persistent left upper abdominal pain andlorhistory of frequent ep...
