I am theoretical physicist. I do research on radiofrequency electromagnetic waves. I like watches and pens. And also magnets. Soy físico teórico. Investigo en ondas electromagnéticas de radiofrecuencia. Me gustan los relojes y las plumas. Y los imanes.

Un pajarito choca con un taxi y se desmaya, el taxista se baja corriendo, levanta al pajarito y lo mete en una jaula. Cuando el pajarito despierta dice asustado. —¡Ostias!, he matado al taxista. 😂😂😂😂

#cosmology 1) Total amount of matter and energy in the Universe, including all types of both; 2) Speed at which the Universe is expanding; 3) Curvature of the Universe.

Ayuso está contra las cuerdas por los protocolos de la vergüenza, por los delitos de su novio, con manifestaciones por la Educación, manifestaciones por la Sanidad... ...pero según ella, el que está de fango hasta las orejas es el Gobierno.

#cosmology Riemann, Christoffel, Levi-Civita, and Ricci can be considered the fathers of tensors. Their work has made it possible to study geometric concepts using the curvature tensor.

#cosmology Tensors provide a powerful theoretical framework for many physical theories: elasticity, electrodynamics, and general relativity.

#cosmology A tensor is an algebraic object that describes a multilinear relation within a vector space. A tensor can be represented by an N-dimensional matrix.

#cosmology The Schwarzschild metric tensor allows us to represent the geometry of space-time around an isolated and static spherical body (which neither vibrates nor rotates around itself).

#cosmology The German mathematician Bernhard Riemann (he only lived 40 years, in the XIX century) advanced the study of these geometries by introducing the metric tensor.

Querido #DiarioDeCosasBonitas : Hoy he vuelto a ver el Sol, después de bastantes años. Con un telescopio con filtro. No se veía con tanto detalle como en la imagen (ojalá 😅) debido a que el filtro era genérico (lo que hace es "oscurecer" para poder mirar) pero resulta fascinante verlo en vivo.

#cosmology Our intuition tells us that the Universe must be in the shape of a sphere, perhaps in four dimensions. But Nature has chosen a quite different Universe: a flat Universe. That is what is deduced from the data that we handle at the moment.

Parece una nebulosa, pero es una estrella en sus "primeros milenios de vida" en la nube oscura L1527. Así de espectacular se ve la formación de una estrella cuando aún no ocurre la fusión nuclear en su interior de manera estable ✨ 📸: NASA, ESA, CSA y STScI, J. DePasquale, A. Pagan y A. Koekemoer

#cosmology Since 1915, we've known that space is warped by the presence of matter and energy, and now we can witness those effects and measure them.

#cosmology According to supersymmetric theories, Weakly Interacting Massive Particles (WIMP) could be generated in the experiments designed at the Large Hadron Collider (LHC) at CERN in Switzerland.

#cosmology The collision of two Weakly Interacting Massive Particles (WIMP) would generate electromagnetic waves that we could detect and, indirectly, we would be obtaining evidence of these WIMP.
