Quantum field theory has been the paradigm of modern physics since it was formulated in the first half of the last century. It is based on the idea that everything in physics corresponds to the interaction of some fundamental fields […]

The wave nature of light expresses itself in the propagation all over space, showing an intrinsic limitation to be localized beyond the so-called diffraction limit which is of the order of half the wavelength of the photons propagating. However when […]

A translucent material allows light to pass through, but if we try to look an object behind such a material, the image will appear blurred or distorted. Think, for example, of the semitransparent glasses commonly used as showers screens. The […]

Thermodynamics is one of the oldest and more fruitful fields of science. Quantum mechanics, on the other hand, is less than one hundred years old, but it is also useful and well accepted. They can look very different. Thermodynamics treats […]

Quantum mechanics is one of the most fruitful and accepted physical theories. Nevertheless, its foundations and philosophical implications are still a vivid topic of debate. Because of that reason, during the conference “Quantum Physics and the Nature of Reality,” held […]

We are almost sure: we have discovered the Higgs boson. Or at least, that is the most reasonable comment to do after the usual Winter Report given by the scientists that work on the two main experiments placed at the […]

Quantum mechanics and biology are very different fields. The first one studies things that are very small, like atoms, molecules or particles. Biology, on the other hand, deals with complex and big systems, the living beings. Of course, that does […]

 
Easter Island is an amazingly mysterious destination due to the moais, megalithic statues resembling human figures that were built by the Rapa Nui people between the 12th and 17th centuries. These magnificent volcanic rock statues […]

Back in the decade of 1950, and inspired by the beauty of the formulation of Quantum Electrodynamics, carried out by Feynman among others in the first half of the twentieth century; scientists thought that all physics had to be invariant […]

Where is the half of the ordinary matter in the universe not observed yet? Computer simulations of cosmological galaxy formation predict the existence of large intercluster filaments of hot and low-density gas, the so-called cosmic web. For the first time, […]
