The Big Chandra Picture

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.

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. 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. Unfortunately, for those who eat pizza as an excuse to drink beer, pizza (loaded with latent calories and served above body temperature) induces an opposite effect. Happy eating!

Match Stick Rocket Match Stick Rocket SUBJECT: Rocketry TOPIC: Propulsion DESCRIPTION: A small solid propellant rocket is made from a match and a piece of aluminum foil. CONTRIBUTED BY: Steve Culivan, KSC EDITED BY: Roger Storm, NASA Glenn Research Center 2 match book matches or wooden stick matches Small square of aluminum foil Paper clip Safety pin Take one match and wrap a small piece of aluminum foil around the match-head. Caution: Be sure the match rocket is pointed away from people or burnable materials. it is recommended to have water or some other fire extinguishant available. DISCUSSION: The match stick rocket demonstrates Isaac Newton's Laws of Motion as they relate to rocketry. In an interesting variation of the experiment, try making holes of different diameters to let the combustion products out at different rates.

The Ethical Hacker Network - Hacking For Dummies: Ch 1 - Intro to Ethical Hacking "Ethical hacking" is the process of entering into a hacker's mindset in order to spot system vulnerabilities by performing typical hacks in a controlled environment. This book helps security professionals understand how malicious users think and work, enabling administrators to defend their systems against attacks and to identify security vulnerabilities. This is yet another great introduction to a topic for the Dummies Series. Chapter 1 – Ethical Hacking In This Chapter · Understanding hacker objectives · Outlining the differences between ethical hackers and malicious hackers · Examining how the ethical hacking process has come about · Understanding the dangers that your computer systems face · Starting the ethical hacking process This book is about hacking ethically and the science of testing your computers and network for security vulnerabilities and plugging the holes you find before the bad guys get a chance to exploit them. How Hackers Beget Ethical Hackers We’ve all heard of hackers. 1.

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. It is one of thousands of planets discovered outside our solar system via the Kepler space telescope — and the first one that is slap-bang in the middle of what astronomers (really) call the Goldilocks zone: not too hot, not too cold, just right for life. 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.

The Chord Guide: Pt I - Chord Progressions Chord progressions are the canvas on which musicians paint their masterpieces, and it’s a canvas which is a piece of art in itself. A chord progression can be subtle and in the background or it can be blatant and up front; it can be simple and catchy, or it can be technical and complex, it can stay in one key or it can change like the seasons. In any of these cases a chord progression is what drives the song as it literally shapes the music that accompanies it. Chord progressions are like a cozy home where melody and rhythm can kick their feet up. All the songwriting giants, like John Lennon, Paul McCartney, George Harrison, and Bob Dylan, to name a few, have/had a tremendous knowledge of the art of the chord progression. I’m not going to promise you tremendous knowledge, but I will offer you a good head start in the way of making your own music – in an easily digestible chunk to boot. Chord Progression Guide Major Chord Chart Above is a chord chart for the 7 most used keys. Chord Theory

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

40 Belief-Shaking Remarks From a Ruthless Nonconformist | Raptitude.com - StumbleUpon If there’s one thing Friedrich Nietzsche did well, it’s obliterate feel-good beliefs people have about themselves. He has been criticized for being a misanthrope, a subvert, a cynic and a pessimist, but I think these assessments are off the mark. I believe he only wanted human beings to be more honest with themselves. He did have a remarkable gift for aphorism — he once declared, “It is my ambition to say in ten sentences what others say in a whole book.” Even today his words remain controversial. Here are 40 unsympathetic statements from the man himself. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21. 22. 23. 24. 25. 26. 27. 28. 29. 30. 31. 32. 33. 34. 35. 36. 37. 38. 39. 40.
