MSc Computer Science (University of Málaga, 1992), MSc Physics (UNED, 1993), PhD Mathematics (University of Málaga, 1998). Associate professor of computer science and artificial intelligence at the faculty of engineering of the University of Málaga. His research interests are applied mathematics and computational physics with a focus on non linear waves.

Black holes are vacuum solutions of the Einstein equation. Hence, the energy-momentum tensor for a black hole is null at every point of space. The only place where its mass can be located is where there is no space, i.e., […]

Nanopore DNA sequencing was one the ten scientific breakthroughs of 2016 highlighted by Science magazine. In principle, graphene is the perfect pore material for DNA sequencing . Its monoatomic thickness of 0.35 nm is similar to the DNA base spacing […]

Luthiers still use Chladni figures in the design and construction of acoustic instruments such as violins, guitars, and cellos. The technique invented by the German physicist and musician Ernst Chladni (1756–1827) shows the modes of vibration under forcing. The backplate […]

Graphene is a two-dimensional allotrope of carbon made of hexagons. In February 2015, penta-graphene, only made of pentagons, was theoretically proposed as another two-dimensional allotrope of carbon . Apparently, it is dynamically, thermally, and mechanically stable, exhibiting a large band […]

Our universe is not stable according to the currently measured values of the top quark and Higgs particle masses. There is a non-null probability that at any instant in the next billions of years the present “false vacuum” will change […]

Lithium-ion batteries are widely used in portable electronic devices and electric vehicles since their introduction by Sony in 1991. Safety is an important concern since about two billion cells are produced every year but with a one-in-200,000 failure rate. Excessive […]

The standard three-layer model for the interior of Jupiter and Saturn claims that an outer layer of molecular hydrogen surrounds an inner layer of liquid metallic hydrogen, with a probable rocky, molten core. The Z machine at Sandia National […]

The Penrose–Hameroff theory of orchestrated objective reduction (Orch OR) claims that quantum computations in the brain account for consciousness . The communication among neurons by the secretion of neurotransmitters is based on synaptic vesicles distributed along their axons. The […]

The sci-fi thriller Ex Machina (2015), directed by Alex Garland, has put into limelight the problem of consciousness: whether a machine can spontaneously develop a mind, mental states, and consciousness. Everyone recalls that IBM’s Deep Blue beat the chess […]

The ribosome may be a missing link in the evolution of life. This suggestive proposal has been published by Meredith Root-Bernstein, Oxford University, UK, and her father Robert Root-Bernstein, Michigan State University, USA, in the Journal of Theoretical Biology […]
