Astronomy Offers Fresh Look at Vermeer's 'View of Delft'

Astronomy Offers Fresh Look at Vermeer's 'View of Delft'

Dutch Golden Age artist Johannes Vermeer is known for creating iconic works like Girl With a Pearl Earring. But it was his View of Delft that French novelist Marcel Proust deemed “the most beautiful painting in the world.” Now, an astronomer has studied the 17th-century cityscape’s depiction of light and shadow to pinpoint the moment that inspired the artist down to the hour, reports Daniel Boffey for the Guardian.

Art historians have long thought that View of Delft was painted in the late spring or early summer of 1660, but the details of Vermeer’s life are so hazy that no one could be sure exactly when the masterwork came to fruition, according to Jennifer Ouellette of Ars Technica.

Donald Olson, an astronomer at Texas State University, and his colleagues used Google Earth and maps from the 17th and 19th centuries to identify landmarks in the painting. Then, they measured the distances and angles of its shadows and highlights. As the Guardian notes, the team even visited Delft firsthand to deduce the position of the sun—and thus the time of year—associated with a slice of light seen on the Nieuwe Kerk tower’s belfry in Vermeer’s skillful rendering.

“That’s our key. That’s the sensitive indicator of where the sun has to be to do that, to just skim the one projection and illuminate the other,” Olson tells the Guardian. “The pattern of light and shadows was a sensitive indicator of the position of the sun.”

Vermeer’s depiction of light and shadow on the stone octagon of the Nieuwe Kerk tower matches this photograph taken when the Sun’s azimuth was near 110° (that is, 20° south of east) on October 16, 2019.

In View of Delft, several of the tower’s eight faces are lit, while others remain in shadow.

Speaking with Ars Technica, Olson says, “The best part is one of the faces is largely dark, but it is projection lit. That’s a very unusual lighting effect, [and] it only happens for a few minutes.”

Per a statement, the researchers concluded that the painting frames a view to the north, meaning its light comes from the southeast, not the west as most sources claim. This observation indicates that the painting depicts the city in the morning.

The scientists’ findings, published in the September 2020 issue of Sky & Telescope, also address what they deem a misinterpretation of the tower’s clock hands. Previously, experts had suggested the clock read just past 7 a.m., its hour and minute hands forming a straight line across its face. After consulting architectural experts, however, the team realized that clocks of that era didn’t have multiple hands. Instead, they featured just one long hour hand, nudging the time forward to around 8 a.m. (Minute hands didn’t emerge until late in the 19th century, according to the statement.)

Historical records indicate that workers installed the Nieuwe Kerk’s bells between April and September 1660. Since the tower’s belfry is empty in the painting, the researchers surmised that Vermeer must have created the painting in or before 1659.

This overview shows the scene of View of Delft as it appeared on the morning of October 10, 2019, from a window 90 feet above water level.

(Donald Olson)

Armed with these parameters, the team used astronomical software to simulate the sun’s position at various times of the year. Based on these simulations, only the periods of April 6 through 8 and September 3 through 4 could have produced the lighting seen in the painting.

The last step in the scientists’ process of elimination centered on the trees in the painting, which wouldn’t have been as verdant and leafy as they appear in Vermeer’s work in April. By eliminating the April timeframe, Olson and his colleagues finally homed in on a new date and time for Vermeer’s masterpiece: around 8 a.m. on September 3 or 4, 1659 (or the year prior).

Speaking with the Guardian, Lea van der Vinde, a curator at the Mauritshuis in the Hague, which has housed the painting in its collections since 1822, calls the astronomers’ research “fun, interesting and exciting.”

Independent art historian Kees Kaldenbach, meanwhile, tells Dutch newspaper de Volskrant that he disagrees with the new analysis. He contends that the painting depicts the city in late May, as herring vessels seen in the scene would have been in the midst of preparations for the start of fishing season on June 1.

“I therefore reject their text,” says Kaldenbach. “Facts are facts.”

Becker & Mukai - Time Very Near - a genre stew from two multi-instrumentalists (SaS Recordings)

Parisian cinema composer Jean-Gabriel Becker is best known for idiosyncratic soundscapes, whilst Susumu Mukai is a world-renowned Japanese composer and multi- instrumentalist. Together they’ve created fresh new music that floats effortlessly above traditional genre delineation, with a dubbed-out and experimental melange of modern acid house, post punk, global grooves and clattering beats. Still not complying to genres, ‘Time Very Near’ is their tentacular new album, which gathers sounds and inspiration from an ever-expanding palette of influences, assembled into something amorphously intangible that’s simultaneously refreshing and sharp, meandering and cosmic, futuristic but timelessly vintage. All tracks written and produced by Jean-Gabriel Becker and Susumu Mukai. Jean-Gabriel Becker: synthesisers and machines, guitar, percussion. Susumu Mukai: synthesisers and machines, bass, percussion, drums.

Miller indices to polyhedra

Using OpenSCAD CSG operations

A while back (well 6 years ago) , I got interested in computing gem cuts in OpenSCAD.  My approach then used the CSG operations to put facets on a sphere as in this post on diamond cuts. The specification of a gem facet uses spherical coordinates : azimuth,  polar angle and radial distance. These correspond to the settings on a faceting machine with which muliple facets around the z axis can be cut at even increments by stepping the azimuth for a fixed polar angle. 

This led to an interest in crystal forms and the use of Miller indices to define the form.  Individual faces are defined by the normal to the face and its distance from the origin. eg  110,1. My approach here to was to use CSG operations as in this post.  Crystal descriptions use a base indice and symmetry rules which depend on the crystal system, eg  {100} , 1 , cubic  to generate the set of simple face indices - here the 6 faces -  001,010,100,001,010,100  where 1  mean -1 [usually written as 1 with bar over] This worked well and allowed me to create some of the irregular polyhedral in the cubic system as well as crystal forms with descriptions taken from the Dexter programme by Mark Holtkamp .  

Computing vertices and faces

The CSG approach allows the solids to be constructed and printed, but I wanted to be able to produce other forms of the solids, such as the open-face form or a net of the solid.  These transformations require vertex and face data which is not available from the constructed OpenSCAD objects. The aim then was to transform a crystal’s description into vertex/face data computationally.  The full procedure involves a  number of steps:

1.  Expand the crystal description using the defined symmetry rules into a set of simple Miller indices.  This was addressed in the previous work using CSG to create the solids.  So far I have handled only cubic systems.

2   Face normals to vertices The algorithm for this is outlined by Eric Dowty , the developer of the impressive Shape software. Every combination of three faces is intersected,  ignoring those with parallel faces.  Any such vertex which is outside any of the faces, based on perpendicular distance to the face is ignored. Finally we remove duplicate vertices. 

3  Vertices to hull Initial OpenSCAD code for an incremental construction of the hull was provided by Alexander Pruss on Thingiverse which yields triangular faces.  

4  Merge coplanar triangular faces  This stitches together adjacent coplanar triangles to form a polygonal face.

5  Generate forms from the vertex/face descriptions.  Here I am able to use my existing OpenSCAD code to generate solid, wireframe and open-face forms as well as nets, and can also use the conway operations to further transform the resultant polyhedra.

Tolerance is needed on most numeric tests, such as coplanarity, vertex identity and sidedness.

By comparison, the conversion from the representation as vertices and faces to Miller indices is trivial, so the easy way to check that the procedure is working is to round-trip a known solid from polyhedron to Miller and then back to a polyhedron or vice-versa. The only restriction is that only convex solids can be so transformed.

Examples

The Gyroid  (pentagonal icositetrahedron)

The regular version is one of the catalan solids. The pentagonal face is irregular.  In crystallography, the shape has a Miller index of {3 2 1}  and gyroid symmetry, resulting in irregular pentagonal faces.

Openface form

Nets 

Irregular solids 

An advantage of the Miller representation of a solid is that the position of each face can be changed by altering its distance from the origin.  This corresponds to different growth rates on different faces of a crystal, but by Steno’s law,the    law of constancy of interfacial angles, leaves the mineral shape unchanged.  So a random pertubation of the face distances gives rise to a randomly varied solid. Here is a rhombic dodecahedron {110} 

with perturbated faces:

which are now a mixture of 4-,5 and 6-sided faces.

Text on Faces

With a vertice/face description, we can also place text on a face.  Here is a unfair die - made by adjusting the two xy-faces - there are better uses of labeling :)

The solid can also be oriented so it is placed on its largest face for printing.

Compound solids

Another feature of the Miller representation is that we can create compounds of solids by concatenating the lists of Miller indices for each component. So a combination of a cube and a tetrahedron is simple to construct and to vary by  changing the face distances.

One benefit is that a form can be cut in any plane by adding a single indice - for example to cut a crytstal form in half vertically for ease of printing we can add [[0,0,-1],0 ].

Quasi crystal

Physical crystals are a lattice of the same molecule so Miller indices of physical crystals are restricted to integer values.  However computationally we are not so restricted. Many of the regular solids can be created from Miller indices as the work of  Zefiro and Ardigo shows. For example, the regular dodecahedron can be represented as {1 phi 0 } where phi is the golden ratio:

Crystals

The forms of real mineral crystals can be repesented as compounds of a number of simpler forms.  This is one of the forms of Boracite from the Smorf database

and its net:

and this version of Zircon from AuntDaisy on Thinigiverse 

Last word

It’s been a while to get to this stage in the quest to generate crystal forms from Miller representations using only user-space computations in OpenSCAD.  Some code is available on GitHub .  There is still work to do, particulaly to handle crystal systems with non-orthogonal axes. 

I have been inspired and helped by many in the Thingiverse (now sadly only useful as an archive it seems ) and OpenSCAD communities, for which grateful thanks.

NSM – ce cumparam mai exact

Conform MApN, lista de cumparaturi in cazul bateriilor de coasta dotate cu rachete anti-nava NSM ar fi urmatoarea:

2 platforme Centru de Comanda si Control

4 platforme lansatoare a cate 4 rachete

2 platforme reincarcare + mentenanta

1 racheta de exercitiu

33 rachete, 1 urmand a fi trasa la teste acceptanta

piese de schimb si mentenanta pentru minim 2 ani

 Tinand cont de suma, am putea presupune in varianta ultra-optimista ca cele doua C&C pot insemna doua radare, adica un radar la cate doua platforme (practic doua baterii a cate doua lansatore mobile), dar foarte putin probabil. Daca e sa luam ad-literam exprimarea din document, putem spune ca mai degraba nu au prevazut radar in configuratia aleasa.

Numarul de rachete suficient pentru doua “plinuri”, plus o racheta care va fi trasa pentru acceptanta sistemului.

Cel mai probabil ca rachetele sa vina de pe linia de fabricatie din Norvegia.

Totul pentru 200 de milioane de euro + TVA.

Ramane de vazut despre ce radar este vorba, mai ales daca nu este prevazut in configuratia sistemului cumparat.

Configuratii containere lansatoare NSM pentru punte

Si ca sa facem totusi o comparatie, polonezii au cumparat in 2008 24 de rachete NSM, trei platforme de lansare (radarul este unul polonez – TRS-15M Odra-C 3D, la fel camioanele si sistemul de comunicatii – alti bani, alta distractie) pentru aproximativ 125 milioane de euro, pretul include si offsetul.

In cazul acestui contract valoarea offsetului este 100% din valoarea contractului, nu ca ma innebunesc eu dupa offset dar asa putem aprecia mai bine suma pe care o platim noi fata de ce au platit polonezii.

Pentru ca stim cu totii, offsetul creste suma totala platita de client, fara acord de offset platesti mai putin.

In perioada 2014-2017 Norvegia a facut o oferta Greciei pentru doua baterii de rachete anti-nava, pretul vehiculat fiind de 110-120 milioane de euro, cel mai probabil per baterie. Nu se cunosc amanunte despre configuratia bateriilor grecesti si nici despre numarul de rachete implicate.

Configuratie tipica baterie de coasta

O baterie poloneza NSM are in componenta urmatoarele:

» 3x MLV (Missile Launch Vehicles) » 1x BCV (Battery Command Vehicle) » 3x CCV (Combat Command Vehicles) » 1x MCC (Mobile Communication Center) » 1x MRV (Mobile Radar Vehicle) with TRS-15C radar

la care se adauga:

1x TLV (Transport/Loading Vehicle)

1x MWV (Mobile Workshop Vehicle)

Caracteristici radar 3D TRS-15M Odra-C :

Instrumented detection range 240 km

Detection range for a fighter 200 km (6 RPM)

Azimuth 360°

Height 30 000 m

Elevation up to 30°

Va lasam sa descoperiti ce lipseste la noi comparativ cu configuratia poloneza…

Lochbuie stone circle, Isle of Mull, Scotland 2017

This small stone circle is the only one on Mull and stands in a breathtakingly beautiful setting, under the watchful gaze of Ben Buie.

You have to cross an extremely boggy field to reach it, so wear your tallest wellies and be very careful if you don’t want to be found as a bog body in thousands of years. Peat bogs are a type of wetland where the water on the ground surface is acidic and low in nutrients. They are filled with decaying organic matter, usually feature rich biodiversity and from a distance, they look rather homogeneous. However closer up, you discover that peat bogs are actually not that uniform in surface, depth or texture. In fact, they’re quite treacherous as you can never tell how deep (sometimes VERY deep) or spongy your next step is going to be. Hiking through them can be hell, as you can sink in bogs quite quickly.

The circle probably dates to the late Neolithic (3000 BC) or early Bronze Age. There were originally 9 stones, all of local granite. One of the stones has been replaced by a low boulder. The circle is about 12.3 metres in diameter, with the tallest stone about 2 metres high and the smallest about 1.2 metre high. Interestingly, the standing stones have been placed so that their flattest side faces the interior of the circle. There are three outlying stones, one about 5 metres from the circle to the south east. This is a fairly unobtrusive boulder about 1 metre high, and its azimuth of 123° with a very high horizon gives a declination of -12°, of no known significance. The second outlier is a very striking monolith about 3 metres high, standing at least 40 metres to the south west. The azimuth of 223.6° with a horizon height of 0.4° gives a declination of -23.7°, and so indicates the position of the setting sun at the winter solstice. The horizon is now partially blocked by nearby trees. Much further away (about 110 metres) is the third outlier, which is roughly 2 metres high. This stone looks like it has suffered a break near the top and was probably much taller when it was first erected. The bearing of 237° and an altitude of just over 2° gives a declination of -16.0°. This is the declination of the sun at the winter Quarter days in early November and early February.

This application is designed to help you point your dish to the satellite you want. It is not a tool for measuring the signal strength received. To take better advantage, align your dish using this application and tune your signal strength with your receiver or a "signal-meter". Steps: - Choose the satellite you want. - Make sure the location sensors are activated on your mobile. - Once your position is found, press "Calculate". - You will see the desired azimuth and elevation at the top and in the bottom the values returned by your device sensors. - Follow the indication of the arrow until the red circle turns green. - Tune the signal strength with your receiver and TV.

This application is designed to help you point your dish to the satellite you want. You will have access to a list of more than 400 satellites. Once a satellite has been selected, you will be able to read number of information necessary to your installation, such ass its geographical zone (region/country), its position (longitude East or West), its elevation and azimuth as calculate based on your location.

Features: + Works all around the world and with any satellite + Display satellite setting such as Azimuth and Elevation + More than 400 satellites referenced in the app + Search option to quickly find your satellites + Ability to add custom satellites

It has never been easier to adjust your television dish.

Easy positioning and installation of your dish antenna with accurate satellite display:

Dish alignment, pointing and Installation has always been a complicated task, especially if you do not have a clue. That is why I posted this application that will simplify this task and allow you to install and align your antenna or satellite dish without the need to call a specialist.

SatCatcher is a satellite finder and dish pointer, it allows you to orient your antenna to any satellite. Using augmented reality, this application displays the target satellite in space to better choose the location of your antenna or satellite dish and ensure the absence of any obstacle (wall, tree ...). SatCatcher also uses your phone GPS to show your location on a map and shows the direction of the satellite from your position. The compass accompanied by a beep lets you orient your antenna or satellite dish following the acceleration of beeps or the arrow of the compass. The accelerometer is used to verify that the holder of your antenna is vertical.

The antenna or satellite dish adjustment steps: 1- choose a satellite and authorize geolocation to determine the direction of the antenna orientation. 2- Show satellite in augmented reality with your camera and make sure there are no obstacles and validate the location of your antenna. 3. Check that the support of your antenna is vertical. 4. Calculate the polarization and adjust the rotation of the LNB (the head of your antenna) 5. Set the elevation 6- Search orientation with visual and sound assistant 7- Fine adjustments.

For the good functioning of the application, SatCatcher will need the camera, compass, gyroscope, accelerometer and the GPS of your smartphone.

tips: - If your smartphone does not have GPS, you can manually move the "marker" on the card until it points your exact location. Use zoom for more detail. - The compass is very important to adjust your dish, but if your smartphone does not have one, you can still use the application. In this case, it will help you to find clues and marks on the map from your location. It also allows you to calculate the orientation. Than you can use a manual compass to get a good orientation. - Do not hesitate to recalibrate the compass and avoid too close to the antenna arm, because it is sensitive to metallic elements. Try to place your smartphone where there is less magnetic interference.

Status of the Large Size Telescopes of the Cherenkov Telescope Array. (arXiv:1907.10146v1 [astro-ph.IM])

The Cherenkov Telescope Array (CTA) will consist of two arrays of Imaging Atmospheric Cherenkov Telescopes (IACTs) at the northern and southern hemispheres. CTA will feature IACTs with mirrors of three different sizes optimized to cover different energy ranges. The proposed sub-arrays of four Large Size Telescopes (LST) at CTA-North and CTA-South target the lowest energy range between around 20 GeV and 100 GeV. Thanks to their low weight of around 110 tons the LSTs can move by 180 deg in azimuth in 20 seconds for Gamma Ray Burst (GRB) follow-up. An LST has a tessellated parabolic mirror of 23 m diameter equipped with a system of actuators to correct for gravity-induced deformations during data taking. Its low-weight 2 ton camera at the prime focus has a 4.5 deg diameter, 1855 high QE PMTs and an embedded readout with 1 GSps sampling speed designed for data acquisition rates exceeding 10 kHz. A fully equipped LST has been installed at the CTA-North site in 2018 and is expected to be finished commissioning during 2019. The remaining three LSTs in the north will be installed by 2022. We will review the status of the LSTs, describe the installation of the first LST and report on the first results of the commissioning tests.

[ Authors ] Zhao-Qing Feng [ Abstract ] The neck dynamics in Fermi-energy heavy-ion collisions, to probe the nuclear symmetry energy in the domain of sub-saturation densities, is investigated within an isospin dependent transport model. The single and double ratios of neutron/proton from free nucleons and light clusters (complex particles) in the isotopic reactions are analyzed systematically. Isospin effects of particles produced from the neck fragmentations are explored, which are constrained within the midrapidities ($|y/y_{proj}|<$0.3) and azimuthal angles (70$^{o}\sim$110$^{o}$, 250$^{o}\sim$290$^{o}$) in semiperipheral nuclear collisions. It is found that the ratios of the energetic isospin particles strongly depend on the stiffness of nuclear symmetry energy and the effects increase with softening the symmetry energy, which would be a nice probe for extracting the symmetry energy below the normal density in experimentally. A flat structure appears at the tail spectra from the double ratio distributions. The neutron to proton ratio of light intermediate mass fragments (IMFs) with charged number Z$\leq$8 is related to the density dependence of symmetry energy with less sensitivity in comparison to the isospin ratios of nucleons and light particles.
