Neutrino mass

Category : General News

Particle Physics made a hit again. The Nobel prize of Physics was awarded to researchers working in neutrino oscillation. The experiments showing conversion between different types of neutrinos prove that they must have some mass (unlike the initial assumption of the Standard Model). The Swedish Academy called it “Metamorphosis in the particle world“. The Chemistry prize was (again) Biochemistry, and focused in DNA repair.

Molecules on comet

Category : Cosmology , General News

Results from a mass spectrometer on board the Philae lander revealed 16 organic molecules in the surface of the comet Churyumov-Gerasimenko, according to a report in Science. The article is part of a special issue on the comet. The spectrum was recorded about half an hour after the first touchdown and shows four compounds never observed before on comets. Most of the organic compounds contain nitrogen, but not sulphur. The observed molecules include acetone, propionaldehyde, acetamide, glycolaldehyde and etylene glycol. Science has collected other results in his Rosetta web page. Unfortunately these initial results might be also the last since Philae does not communicate since July 9.

Philae wakes up

Category : General News

The Philae space probe woke up from hybernation last June 14 and transmited for 85 seconds. The probe was sitting at the Churyumov-Gerasimenko comet since November 2014, waiting for more sun on its panels. In the following months ten instruments on board Philae, including X-ray and IR spectrometers, a cromatograph and TOF  mass detector, may provide insight about the comet chemical composition and other physical properties. The video below shows the hazardous landing of the probe.

The simulation video was prepared by David Ducros for the French CNES.

New building in Hannover

Category : General News

The Institut of Physical Chemistry in Hannover, with whom who keep a lasting collaboration through Prof. Jens-Uwe Grabow, celebrated the dedication of their renovated building last June 11th. The ceremony was chaired by the President of the Leibniz-University of Hannover and included several invited guests. The Nobel laureate Sir Harry Kroto gave a brief presentation, since he designed a new wall drawing for the Institute, inspired in the diffraction pattern of a quasicrystal. Alberto was at the ceremony as part of a short visit to Hannover.

Int’l Year of Light

Category : General News

UN & UNESCO have promoted 2015 as the International Year of Light, IYL 2015. This global initiative will highlight “the importance of light and optical technologies for people’s lives, futures, and development of society”. A committee of the Spanish Optical Society (SEDOPTICA) will organize different activities around the year from the web “Año de la luz 2015“.

Digital Einstein

Category : General News

NYT informs that papers, notes and correspondence of Albert Einstein are now freely available on the “Digital Einstein” web page. The web is part of the Einstein Papers Project, which has published 13 paper volumes edited by Diana Kormos-Buchwald. The web includes a useful English translation. As a side note Einstein got a rank of 0.5 in Lev Landau’s list, a logarithmic scale of physicists productivity (Newton was ranked 0, while Bohr, Heisemberg, Schrödinger and Dirac got 1). A translated excerpt from “The Electrodynamics of Moving Bodies” (1905) is shown below.

Landing in a comet

Category : Cosmology , General News

The European Space Agency put a 98 kg space probe in the surface of the comet 67P/Churyumov–Gerasimenko. The Philae probe bounced back into space a couple of times before landing, since the escape velocity from the comet is only 1.8 km/h. Science went well till Philae batteries exhausted. The Rosetta spacecraft will continue monitoring the comet for at least one year. More results to come.

The orbital approach to the comet is shown in the video below.

Spallation Neutron Source

Category : General News

The new European neutron spallation source will go to Lund (Sweden). Bilbao compited for this facility without success. The Swedish funding for this project is equivalent to ca. 50 km of high-speed train, but unthinkable in Spain. According to ESFRI boss Prof. John Womersley “it would have been better for Spain to build scientific facilities instead of airports and auditoriums…”. A new report from the Spanish Consortium of Scientific Societies (COSCE) recently expressed that the new 2015 national budget for Science “mantains the budget cuts and does not promote R+D“.

In the movie below coffe making is observed using a neutron source.

Cosmological inflation

Category : Cosmology , General News

Observations in Antarctica with the BICEP2 experiment measuring the polarization of the cosmic background radiation seem to confirm the model of cosmological inflation and the big bang. The inflationary epoch was a practically instantaneous period of the early universe (10-36 to 10-32 seg after big bang) where the space expanded much faster than the speed of light. If you haven’t read it yet buy inmediately the book by Lawrence M. Krauss “A Universe from nothing” (…with an introduction by Richard Dawkins).
