"Artists, emotionally, have more tools for being isolated. "I was really worried about more of the world outside of art, first of all," Collado says of the truncated residency. A wealth of programming was intended to accompany the work, including workshops bringing together children and adults. She planned to finish it during her residency, traveling back and forth between New Orleans, Florida, and the Dominican. Oolite had awarded Collado an Ellies Award grant for a project collecting and archiving oral traditions and mythology from the Dominican Republic. Photo by Diana Larrea The limitations of residencies in the COVID era became very real for sculptor Yanira Collado in March, when she had to abruptly leave her Joan Mitchell Foundation residency. And the same with the artists - we can't just say, 'Here's a residency program.' We have to find a way to reach more artists and to help more artists." We need to meet our audience now where they've gone to, not where they used to be. "We have to adjust our goals, adjust our aspirations, adjust our strategy. We can't keep doing things the way we've been doing them for decades," Scholl says. Pérez Family Foundation, and the Miami-Dade County Department of Cultural Affairs. But immediate support doesn't quite address the real scope of what needs to change. This was followed by similar relief programs from the City of Miami Beach, the Jorge M. Requiring little more than a CV and proof of address, Oolite was able to get almost a quarter of a million dollars to 464 artists across the county. Oolite first mobilized a small stipend for its residents, followed by a relief fund for visual artists across Miami-Dade County. And we're concerned that it will be the last thing to come back." "The visual artists in our community generally work out of a gig economy, and the gig economy is the first thing to go away with a crisis like this. We were concerned about artists making rent, food security for artists," Scholl recalls. "Literally, within ten days of the lockdown, we went to work on a relief fund. As president and CEO of Oolite Arts, Scholl immediately anticipated the fallout that would confront artists. "Visual artists in our community generally work out of a gig economy, and the gig economy is the first thing to go away with a crisis." tweet this This was on Dennis Scholl's mind early in the outbreak of COVID-19. "Without us, what is Oolite going to be about? They can't do that without artists, and artists can't function without some form of support and encouragement." "There's something empowering in knowing that they recognize the importance of the arts, especially through a time like this," Vasquez says. ![]() Vasquez hasn't changed who he paints, but he did begin working on a smaller scale as he shifted his practice from his shared studio to his home.īut with the launch of Oolite Arts' acquisitions program this month, the artist has had something to be productive for and to look forward to in the form of a commission for Oolite's space in Little River slated to open in 2023. ![]() ![]() It's almost reassuring to see that art's ability to crack open representations and reveal us to ourselves hasn't been lost in the pandemic, even as many other things disappear or transform. My work, without me doing anything or changing a thing, has shifted through this time." ![]() And then somehow, still, painting the same people, the essential workers became protesters or activists. "When the pandemic hit, they were essential workers. "Prior to this, they were gang members," Vasquez says of his subjects. Bandanna face coverings have been part of his visual repertoire for years. Vasquez has made a career out of painting vibrant, dynamic portraits and tableaus of street subculture and gang life. Not visually and not by me changing something, but by the current state of things informing people's notions of who these people are that I depict," Vasquez explains. "At the beginning of all this - the pandemic and even prior to the protests - I began thinking about how my work can shift. Without having to do much of anything, painter Michael Vasquez has seen his art transform over the past several months. So if he abandons the project, someone else can hypothetically pick it up. However, GPMDP is also open-source, with its source code available on Github. So he's not obligated to keep updating it, and his interests may change. The app and your use of it are completely free, because it is a student project.īecause the app is a student project, its future is unclear: Samuel Attard began developing GPMDP as a teenager, in college, as a freely available engineering project, rather than a product he intended to make money off of. Three, there is no attempt to make a financial transaction. We know more about him than we do about the people who make Google Play Music, itself. He prominently displays his full name, physical appearance, place of residence, multiple methods of contact, and even where he goes to college. Two, the app creator, Samuel Attard is not anonymous. ![]() If you try to access your Google account from within GPMDP, you actually get redirected to an external web browser window. ![]() One, the app is mostly acting as a front end for the Play Music website, so it can't intercept your log-in info. But we know that we can make an exception for GPMDP for a few reasons. You may be leery about using your Google account password in the app: It's healthy to be skeptical when a non-official app asks for your password. The unofficial Desktop Player app is the only way for Play Music to replicate a function that Spotify users have enjoyed for years. You need a Chromecast, Nexus Player, or other officially supported device. How is this different from just using Google's mobile app to cast to a local device? Surprisingly, the official app doesn't let you cast to your computer, even if you have Play Music loaded in a Google Chrome browser tab. So your compatible smartwatch can use the app, too. You get music controls, playlists, search, and the ability to play specific songs, plus the app is compatible with Android Wear. Making it a permanent resident of the UI can help alleviate some anxiety about accidentally removing a song from your library, and it's also a better reminder that your trash is automatically emptied after 60 days.Ī free remote player mobile app for Android: As its name implies, Remote for GPMDP is a free Android app that interacts directly with the Desktop Player, over your local Wi-Fi connection. ![]() The Trash section exists in the web version of Google Play, but you can't see it unless there's something in it. You can set the Player app to open when you start your computer, enable voice control, use a mini player widget, link the app to a Last.FM account, create keyboard shortcuts for a variety of common actions, and even try out experimental support of 5.1 surround sound. The additional features are welcome and sensible: While the visual design of GPMDP is nearly identical to the web version, you'll notice a few additional items when you click on the hamburger menu in the upper left corner, chiefly "Desktop Settings" and "Trash." Clicking on Desktop Settings opens up a whole new layer of functions and interaction. Its advantages come in what it can add to the experience, rather than attempting to alter what's already working. It doesn't try to reinvent the wheel: Play Music doesn't have a bad interface, so why fix what isn't broken? For the most part, Google Play Music Desktop Player (GPMDP) seeks to mirror the look and feel of the in-browser experience, for maximum familiarity. Have Play Music fans been missing out by not having a Spotify-like desktop experience? Let's investigate. Generally speaking, Google's mobile services come from a kaleidoscope of individual apps, but us lowly Windows and Mac users get corralled into a web browser tab when we want to load up Gmail, Drive, Photos, Maps, and so on. ![]() Although Google Play Music (GPM) competes directly against Spotify and other streaming services, it actually doesn't have its own desktop app. If you choose to do business with this business, please let the business know that you contacted BBB for a BBB Business Profile.Īs a matter of policy, BBB does not endorse any product, service or business.

However, these mirror symmetries should not lie on the straight sides of the polygon tiles. To create a tessellation by bilaterally symmetric tiles, we need to start with a geometric pattern that has mirror symmetries. The less common triangle systems are easily identified because three or six motifs will meet at a point, and the entire tessellation will have order 3 or order 6 rotation symmetry.įigures with bilateral symmetry are naturally easier to make into recognizable figures, because many natural forms have bilateral symmetry. The bulk of Escher’s tessellations are based on quadrilaterals, which the novice will find much easier to work with. All of Escher’s tessellations by recognizable figures are derived from just a handful of geometric patterns.Įscher created his tessellations by using fairly simple polygonal tessellations, which he then modified using isometries. Escher organizes his tessellations into two classes: systems based on quadrilaterals, and triangle systems built on the regular tessellation by equilateral triangles. He used these figures to tell stories, such as the birds evolving from a rigid mesh of triangles to fly free into the sky in Liberation. Though Escher’s goal was recognizability, his tessellations began with geometry, and as he grew more accomplished at creating these tessellations he returned to geometry to classify them. He wanted to create tessellations by recognizable figures, images of animals, people, and other everyday objects that his viewers would relate to. The most common tessellations today are floor tilings, using square, rectangular, hexagonal, or other shapes of ceramic tile. Escher’s primary interest in tessellations was as an artist. It also explains how they can be transformed using translation, rotation and glide reflection to create shapes like fish.Ī tessellation, or tiling, is a division of the plane into figures called tiles. It shows a simple visual demonstration of tessellating triangles, squares and hexagons. Escher inspired Tessellation Art, which explains the basic principles behind tessellating shapes and patterns. What is Tessellation? An educational video animation by M. Although the radiation created in the solar core consists mostly of x rays, internal absorption and thermalization convert these super-high-energy photons to lower-energy photons before they reach the Sun's surface and are emitted out into space. The Sun emits EM radiation across most of the electromagnetic spectrum. The spectrum of the Sun's solar radiation can be compared to that of a black body with a temperature of about 5,800 K (see graph). See also: Ultraviolet, Infrared, and Light (However, the radiance at the center of the sun's disk is somewhat higher than the average over the whole disk due to limb darkening.) Multiplying this by π gives an upper limit to the irradiance which can be focused on a surface using mirrors: 48.5 MW/m 2. Averaged over a day, the highest amount of sunlight on a horizontal surface occurs in January at the South Pole (see insolation).ĭividing the irradiance of 1,050 W/m 2 by the size of the Sun's disk in steradians gives an average radiance of 15.4 MW per square metre per steradian. The illumination of a horizontal surface will be considerably less than this if the Sun is not very high in the sky. Multiplying the figure of 1,050 watts per square meter by 93 lumens per watt indicates that bright sunlight provides an illuminance of approximately 98,000 lux ( lumens per square meter) on a perpendicular surface at sea level. This is higher than the efficacy (of source) of artificial lighting other than LEDs, which means using sunlight for illumination heats up a room less than fluorescent or incandescent lighting. ĭirect sunlight has a luminous efficacy of about 93 lumens per watt of radiant flux. At the top of the atmosphere, sunlight is about 30% more intense, having about 8% ultraviolet (UV), with most of the extra UV consisting of biologically damaging short-wave ultraviolet. In terms of energy, sunlight at Earth's surface is around 52 to 55 percent infrared (above 700 nm), 42 to 43 percent visible (400 to 700 nm), and 3 to 5 percent ultraviolet (below 400 nm). If the extraterrestrial solar radiation is 1,367 watts per square meter (the value when the Earth–Sun distance is 1 astronomical unit), then the direct sunlight at Earth's surface when the Sun is at the zenith is about 1,050 W/m 2, but the total amount (direct and indirect from the atmosphere) hitting the ground is around 1,120 W/m 2. It is about 3.3% higher than average in January and 3.3% lower in July (see below). The total amount of energy received at ground level from the Sun at the zenith depends on the distance to the Sun and thus on the time of year. The atmospheric extinction brings the number of lux down to around 100,000 lux. ![]() Where c is the atmospheric extinction and m is the relative optical airmass. The extraterrestrial solar illuminance ( E ext), corrected for the elliptic orbit by using the day number of the year (dn), is given to a good approximation by E e x t = E s c ⋅ ( 1 + 0.033412 ⋅ cos ( 2 π d n − 3 365 ) ), To calculate the amount of sunlight reaching the ground, both the eccentricity of Earth's elliptic orbit and the attenuation by Earth's atmosphere have to be taken into account. ![]() Researchers can measure the intensity of sunlight using a sunshine recorder, pyranometer, or pyrheliometer. ![]() Solar irradiance is the solar energy available from sunlight. Sunlight is a key factor in photosynthesis, the process used by plants and other autotrophic organisms to convert light energy, normally from the Sun, into chemical energy that can be used to synthesize carbohydrates and to fuel the organisms' activities.ĭaylighting is the natural lighting of interior spaces by admitting sunlight. A photon starting at the center of the Sun and changing direction every time it encounters a charged particle would take between 10,000 and 170,000 years to get to the surface. Sunlight takes about 8.3 minutes to reach Earth from the surface of the Sun. The ultraviolet radiation in sunlight has both positive and negative health effects, as it is both a requisite for vitamin D 3 synthesis and a mutagen. Sources estimate a global average of between 164 watts to 340 watts per square meter over a 24-hour day this figure is estimated by NASA to be about a quarter of Earth's average total solar irradiance. When blocked by clouds or reflected off other objects, sunlight is diffused. When direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat. ![]() On Earth, sunlight is scattered and filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon.
