      This video I did in La Picota (Huelva), a place recommended by the Andromeda Astronomical Association. The night was pretty starring the moon, so I hope to do something better and with more time.

        • la revolution de copernicus et galileo qui nous a mis hors du centre du cosmos


          from j.l.knopf Added

          the revolution of copernicus made us loose the thought position of being the centrepoint of the universe and galileo did his part to ban us to someother outskirt instead. that is the grand scale revolution. there's also one on a smaller scale: the one which makes the child realise that it's not the centrepoint around which the world and maybe also the universe turns. both macro and micro versions of the copernican and galilean revolution let us see the world and all that which belongs to it in the right proportions. the images are partly historic images of our solar system, combined with present time images of nasa. the music is a live recording of 'the new clara schumann band' made at the art festival 'cultuurbarbaar/walter benjamin' which was held earlier this year in leiden, the netherlands.

          • Large Sky Surveys - Joshua Bloom, University of California, Berkeley


            from Kavli Frontiers of Science Added 101 0 0

            The Transient Universe Joshua Bloom, University of California, Berkeley Every astrophysical entity changes in time and it is through the measurements of those changes, however difficult, that the physics of this dynamic universe comes to light. A confluence of technological advances is poised to open new vistas on the “transient universe”: the exploding size of time-domain parameter space is truly revolutionary. The next generation synoptic surveys -- those performing repeat observations in the same portion of the sky -- will facilitate new science with commonly studied phenomena and reveal entirely novel sorts of events, both the hypothesized and the unpredicted. I highlight some new lines of inquiry in time-domain astronomy, using recent discoveries as the point of departure. I will particularly focus on the promising, yet observationally challenging, events to bridge gravity waves to the electromagnetic spectrum. The sheer data rate, approaching one Petabyte per night for visible light surveys, presents not just logistical and computational barriers but conceptual hurdles. Indeed the rapid creation of ``knowledge’’ from these data require fundamentally new solutions from computational sciences, likely involving cutting-edge machine learning techniques and massively parallel algorithms. Glossary items: Redshift - the apparent reddening of light due to motion away from an observer or due to the expansion of the universe. The measurement of redshift from the most distant objects is considered a good proxy for the distance to that object Supernova - highly energetic explosions with significant energy releases at visible wavelengths over the period of days to weeks. Some types are sssociated with the death of massive stars while others are thought to be due to merger of white dwarfs White dwarf star -- a compact star about the size of the Earth but containing about the mass of the Sun. It is supported against collapse by a quantum mechanical effect called electron degeneracy pressure. The Sun will end it’s life as a white dwarf. Black hole -- known to exist on small and large mass ranges, black holes represent the densest form in nature. Though there is no hard boundary, the size of a black hole usually refers to the distance from the center out to which no light can escape. This size is directly proportional to mass. chirp signal -- the waveform of merging objects representing the compression and expansion of space as a gravity wave sweeps by a fixed observer. Petabyte - roughly 1000 terrabytes, or 1 million gigabytes

            • Large Sky Surveys - Julien Guy, IN2P3/LPNHE


              from Kavli Frontiers of Science Added 52 0 0

              Large Sky Surveys Julien Guy, IN2P3/LPNHE Type Ia supernovae are the explosive death of a small fraction of stars. Those events are as bright as ten billion suns for about a month, which is of the order of the total brightness of their host galaxy. Hence, they can be detected on cosmological scales, up to redshifts of unity on ground based telescopes, and at even larger redshifts from space. Their intrinsic luminosity can be inferred from their color and the shape of their light curves (luminosity integrated in several pass-band filters as a function of time) using empirical models of their spectral evolution. The ratio of the observed to intrinsic luminosity provides us with a distance estimate, which, once combined with a redshift measurement, allows us to map the expansion history of the Universe. Using this technique, two teams have shown independently in 1998, that type Ia supernovae at high redshift were dimmer than expected in a matter dominated, decelerating Universe. This observation has changed radically our understanding of cosmology: something is responsible for a recent acceleration of the expansion of the Universe, we have called it "Dark Energy". Since that time, several surveys have confirmed this result and put more stringent constraints on the properties of this Dark Energy. Among those, the Supernova Legacy Survey which is still going on, has discovered and monitored about 300 of those high redshift supernovae. The precision on cosmological parameters that can be reached with this dataset, is no longer limited by the number of supernovae, but by the numerous small systematic uncertainties that enter in the derivation of luminosity distances.

                  from Gresham College Added 100 1 0

                  Beyond the Solar System, all astronomers have to work with is the light that falls to the Earth from distant cosmic objects. Newer, larger telescopes are always needed to boost scientific progress, and the next generation of facilities - whether the 42m diameter optical-infrared Extremely Large Telescope, or the Square Kilometre Array of radio dishes - will represent a huge advance. We shall look at the science driving the need for such large telescopes, through history and to the present-day and beyond. Many scientific and engineering challenges are involved in the design and construction of the largest telescopes and their mirrors, and technological developments will be essential to their success. All our lectures are available for free download from the Gresham College website, in video, audio or text formats: gresham.ac.uk Gresham College professors and guest speakers have been giving free public lectures in central London since 1597.

                  • Larkin's Twig, Shadow Studies


                    from Edward Tufte Added 1,039 12 2

                    steel 32' high footprint = 59' x 66' x 70' It is called "Larkin's Twig" because several years ago Graham Larkin, then a graduate student in Art History at Harvard and now a Fellow at Stanford, worked as my intellectual assistant, teaching me some art history and providing materials to read and think about in a kind of correspondence course and tutorial. When Graham came to visit, he would bring a little something each time, such as a book or, once, a beautiful twig about 12 inches high with a very nice natural geometry and graceful, but not mechanically graceful, curves. For years, Larkin's twig sat in an honored place in our library and then in our kitchen. Why not make the twig 32 times bigger? How will it scale up? Should X, Y, and Z scale up differently? (Yes) What should the material be? How will the steel rust? What parts should be revised, extended, modified, reshaped? How is it to hit the land? How will it belong in the natural environment of the landscape? In relation to trees, land contours, and other pieces in the field? What is the proper orientation of the piece and the resulting cast shadows? How will shadows vary in different seasons of the year? How can mock-ups be built to test ideas out? What about structural engineering issues? A Cooper's Hawk perched on a two-thirds scale wooden mockup, will that happen on the steel and do we add a bird-perch? What does it all mean? And so on. Any good 3-dimensional sculpture cannot be captured by one-eyed flatland photographs. This can be seen very strongly with Richard Serra's amazing work at Dia-Beacon. One of many tests of a piece is that photographs do little justice to the reality. That is, you have to be there. How else can volumes in the air be seen? -Edward Tufte For more info go to www.edwardtufte.com
