Thermal Physics Jokes As we all know, it takes 1 calorie to heat 1 gram of water 1 degree centigrade. Translated into meaningful terms, this means that if you eat a very cold dessert (generally consisting of water in large part), the natural processes which raise the consumed dessert to body temperature during the digestive cycle literally sucks the calories out of the only available source, your body fat. For example, a dessert served and eaten at near 0 degrees C (32.2 deg. F) will in a short time be raised to the normal body temperature of 37 degrees C (98.6 deg. F). For each gram of dessert eaten, that process takes approximately 37 calories as stated above. Obviously, the more cold dessert you eat,the better off you are and the faster you will lose weight, if that is your goal. Frozen desserts, e.g., ice cream, are even more beneficial, since it takes 83 cal. Happy eating! School of Physics, University of Sydney

Chandra :: Photo Album :: The Big Chandra Picture The Big Chandra Picture In more than a decade of operation, NASA's Chandra X-ray Observatory has transformed our view of the high-energy Universe with its ability to make exquisite X-ray images of star clusters, supernova remnants, galactic eruptions, and collisions between clusters of galaxies. As Chandra expands the realm of the known, it continues to raise new questions and point the way for future exploration. This photo blog presents some of Chandra's most spectacular images in a large and shareable format. 10 Apr 2014 G352.7-0.1: Supernovas are the spectacular ends to the lives of many massive stars. 03 Apr 2014 El Gordo: This is a composite image of X-rays from Chandra and optical data from Hubble of the galaxy cluster ACT-CL J0102-4915, located about 7 billion light years from Earth. 20 Mar 2014 DEM L241: When a massive star runs out fuel, it collapses and explodes as a supernova. 05 Mar 2014 RX J1131-1231: A quasar located about 6 billion light years from Earth. 04 Mar 2014

Disable All Notification Balloons in Windows 7 or Vista If you find the popup notification balloons in the Windows system tray to be too annoying, you might be interested to know that you can completely disable them. This would be an extreme option, of course… typically you can just turn them off in any offending applications, but if you want to disable them across the board, this is the solution. Note: This should work in any version of Windows. Note: I’m not necessarily recommending that everybody do this… you should only bother with it if you need to solve this particular problem. Manual Registry Hack Open up regedit.exe through the start menu search or run box, and then browse down to the following key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced Right-click on the right-hand pane, and create a new 32-bit DWORD with the following values: Name: EnableBalloonTips Value: 0 You’ll have to logoff and back on in order to see the change… or to be more correct, you won’t see any popup balloons anymore.

UberGallery - The simple PHP photo gallery Earth, Meet Your Long-Lost Sibling: The Christmas Planet It may sound like something from a very special episode of Doctor Who, but the Christmas planet is real. What's more, it's the most Earth-like world yet discovered. The planet, more properly known as Kepler 22-b, was revealed to the world Monday via a press conference at NASA Ames Research Center. So why call it the Christmas Planet? "It's a great gift," said William Borucki, the telescope's principal investigator, who came up with the seasonal name. Actually making our way to the Christmas Planet might take a little longer, however. But we do know it's about twice the size of Earth, and that the average surface temperature is a balmy 72 degrees Farenheit.

LCD Calculator - Least Common Denominator Least Common Denominator Calculator Use this calculator to find the least common denominator of fractions, integers and mixed numbers. We also have calculators for least common multiple, fraction operations, simplifying fractions, mixed numbers operations, and comparing fractions. See additional notes below. How to Find the LCD of Fractions, Integers and Mixed Numbers: To find the LCD first convert all integers and mixed numbers (mixed fractions) into fractions. Steps to find the LCD of fractions, integers and mixed numbers Convert integers and mixed numbers to improper fractions Find the LCD of all the fractions Rewrite fractions as equivalent fractions using the LCD Example using this calculator default sample: Input: 1 1/2, 3/8, 5/6, 3 Convert integers and mixed numbers to improper fractions 3/8 and 5/6 are already fractions so we can use those as they are written. 1 1/2 is the same as (1/1) + (1/2).

Build PDF files dynamically with PHP Sometimes you need control over exactly how pages are rendered for printing. At times like those, HTML is not the best choice. PDF files give you complete control over how pages are rendered and how text, graphics, and images are rendered on the page. When you search the web for PDF support for PHP, the first thing you are likely to find is the commercial PDFLib library and its open source version, PDFLib-Lite. Another choice is the Free PDF library (FPDF), which is native PHP. To demonstrate building PDF files dynamically, you'll use scores from women's roller derby tournaments. Listing 1. <events><event name='Beast of the East 2011'><game score1='88' team1='Toronto Gore-Gore Rollergirls' team2='Montreal La Racaille' score2='11'/><game score1='58' team1='Toronto Death Track Dolls' team2='Montreal Les Contrabanditas' score2='49'/> ... The root element for the XML is an events tag. Listing 2 shows the PHP code that you use to read the XML. Listing 2. getresults.php <? Listing 3. Figure 1.

Scientists find monster black holes, biggest yet CAPE CANAVERAL, Fla. (AP) — Scientists have found the biggest black holes known to exist — each one 10 billion times the mass of our sun. A team led by astronomers at the University of California, Berkeley, discovered the two gigantic black holes in clusters of elliptical galaxies more than 300 million light years away. That's relatively close on the galactic scale. "They are monstrous," Berkeley astrophysicist Chung-Pei Ma told reporters. The previous black hole record-holder is as large as 6 billion suns. In research released Monday by the journal Nature, the scientists suggest these black holes may be the leftovers of quasars that crammed the early universe. The scientists used ground-based telescopes as well as the Hubble Space Telescope and Texas supercomputers, observing stars near the black holes and measuring the stellar velocities to uncover these vast, invisible regions. Black holes are objects so dense that nothing, not even light, can escape. Online: black holes

Mysterious planet-sized object spotted near Mercury | The Sideshow A mysterious object is seen following in Mercury's path Is a giant, cloaked spaceship orbiting around Mercury? That's been the speculation from some corners aftera camera onboard NASA's STEREO spacecraft caught a wave of electronically charged material shooting out from the sun and hitting Mercury. Theorists have seized on the images captured from the "coronal mass ejection" (CME) last week as suggestive of alien life hanging out in our own cosmic backyard. Of course, there's another scientifically sanctioned explanation for the curious images, though we're not certain that skeptics and UFO enthusiasts such as SiniXster will endorse it. Head NRL group scientist Russ Howard and lead ground systems engineer Nathan Rich say the mysterious object is in fact Mercury itself. The analysts say the practice works even better when applied to far-off objects such as stars, which don't move much relative to the sun.
