Pet of the Day - Every day a new pet photo and story Fault creep along the Calaveras in Hollister, California Introduction Hollister, California is located South of the San Francisco Bay area. (Here is a regional map courtesy of Xerox PARC.) In the Bay area there are three major faults, from West to East the San Andreas, the Hayward, and the Calaveras; all are part of the San Andreas fault system. South of the Bay Area the Hayward and Calaveras merge into the San Andreas. What makes Hollister particularly interesting to geophysicists is that from San Juan Bautista (HERE) to just North of Parkfield (HERE) the faults in the San Andreas system are not ``stuck'': instead of moving only during major earthquakes, the usual pattern for faults, they continuously ``creep''. Here is a map showing the approximate active trace of the fault for the part of town covered in our tour. The creep rate apparently varies in an unpredictable way. Hollister has become rather ``yuppified'' over the last decade. Walking Tour Find ``Vista Park Hill'', just NorthWest of downtown. Rogers, T. Sylvester, A. Disclaimer

Taking Type to the Next Level with Alternate Characters Are you sick of your type looking plain and boring? Many OpenType fonts have alternate characters built into them that can transform your type into a beautiful piece of art. By using these alternate characters you can add things like flourishes and flair to your type with ease. Some type faces have alternate characters that can help out with legibility at smaller sizes. Even some handwritten fonts have alternate characters to change the style of a characters to make it seem more handwritten. How do you tell what fonts have alternates? Ligatures – This is where two or more characters are linked together. Logotypes – This is where a word is stylized as a logo to be included in your type. Biform characters – These alternate characters can make capital letters have a lowercase look or lowercase letters with capital letter look while keeping the same size and weight. Swash characters – This is where a certain letter can have a fancy look to them. Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Step 7

Cat of the Day - Every day a new cat photo and story Geysers erupt because they’re all bendy inside University of California at Berkeley volcanologist Michael Manga and student Esther Adelstein built a laboratory geyser to explain how geysers like Old Faithful work. (Roxanne Makasdjian and Phil Ebiner; additional footage by Eric King and Kristen Fauria/University of California at Berkeley) You'll definitely want to check out the video above, because it features a loop-de-loop lab apparatus designed to spew water into the air. But it's more than just a twist on one of those science fair volcano models: The UC Berkeley earth sciences professor who designed it says it demonstrates the basic mechanics of geysers like Old Faithful. Michael Manga and his colleagues report on their findings in the February issue of the Journal of Volcanology and Geothermal Research. Manga's model isn't quite so reliable.

Dog of the Day - Every day a new dog photo and story Floating Farms It is fairly straightforward to measure the area of most lakes. Certain satellite sensors, such as the Operational Land Imager (OLI) on Landsat 8, are particularly well suited to the chore because they collect information from several sections, or bands, of the electromagnetic spectrum that can be used to distinguish between water, land, and aquatic vegetation. However, determining the size of Inle Lake poses a special challenge. The second largest lake in Mynamar (Burma) has a unique agricultural system that makes the boundary between land and water remarkably fuzzy. The system, known locally as ye-chan, involves the cultivation of hundreds of hectares of floating “islands” that produce enough tomatoes and other vegetables to drive the region’s economy. Landsat 8 acquired an image (top) of the southern part of Inle Lake on January 25, 2015. According to one study, the area covered by floating gardens increased by 500 percent between 1992 and 2009.

Hexaflexagon Toolkit Astronomy Sketch of the Day Faults in Xinjiang Just south of the Tien Shan mountains, in northwestern Xinjiang province, a remarkable series of ridges dominates the landscape. The highest hills rise up to 1,200 meters (3,900 feet) above the adjacent basins, and they are decorated with distinctive red, green, and cream-colored sedimentary rock layers. The colors reflect rocks that formed at different times and in different environments. The red layers near the top of the sequence are Devonian sandstones formed by ancient rivers. The green layers are Silurian sandstones formed in a moderately-deep ocean. The cream-colored layers are Cambrian-Ordovician limestone formed in a shallow ocean. The Operational Land Imager (OLI) on the Landsat 8 satellite captured this view of the Keping Shan thrust belt on July 30, 2013. This part of Xinjiang province has a rich and varied geologic history. When land masses collide, the pressure can create what geologists call “fold and thrust belts.” Another type of fault is visible as well. Instrument(s):

How To Give Your Photos a Dark Processed Lomo Effect This post was originally published in 2010 The tips and techniques explained may be outdated. Follow this step by step post processing guide to give your photos a dark lomo style effect with high contrast, blue tones and vignette burns. The effect is based on the popular lomographic technique and is similar to the processing effect used in many fashion shots and advertisement designs. View full size photo effect Begin by opening your photograph of choice into Adobe Photoshop. Go to Image > Adjustments > Levels and tweak the tones of the image. At the bottom of the Layers palette, click the Adjustment Layer icon and select Curves. Change the drop down menu to Green and tweak the graph for the green channel to further alter the tones of the image. Finally alter the Blue channel, creating an inverted ‘S’ shape to enhance the blues to give a cool colour cast. Go to Edit > Select All, then Edit > Copy Merged. Paste another duplicate of the image on a new layer. Download this file
