Of all the advances made in theoretical physics in the last twenty years, I still have no doubt that the most impressive one is the so called Maldacena’s conjecture, the guess that the physics involved in some models of quantum gravity living in a very concrete 5-dimensional spacetime has a one-to-one correspondence with the physics […]

Bicycles are usually regarded as the most sustainable mean of transport for urban environments. Now, when talking about sustainability, there are usually two different discussions: on the one hand, there is energy sustainability, as the fossil fuels won’t last forever and their secondary products are quite unhealthy. Bikes, being powered by people, fully comply with […]

Last month, a lot of newspapers and websites have been promoting this article on Nature referring to a recent preprint uploaded by Stephen W. Hawking to the internet repository ArXiv. In this work, summarizing what he talked about in a conference given last August, the English physicist argue that, since event horizons, the definitory property […]

It has been a long time since we have learned that “going nano” leads to new properties arising from matter. One of those size-dependent properties that promises huge benefits due to its potential applications is magnetism. Magnetic materials are classified according to their susceptibility to magnetic fields into diamagnetic, paramagnetic and ferromagnetic materials, the first […]

Both thermodynamics and quantum mechanics are very important theories, but they are applicable to very different kinds of systems. Thermodynamics describes macroscopic systems where the number of particles is huge (around Avogadro’s number: 6.022×1023). On the other hand, quantum mechanics describes the behavior of microscopic particles. The regimes where these two theories can be applied […]
