More Evidence Our Solar System Is Uniquely Suited for Life

first_img(Visited 60 times, 1 visits today)FacebookTwitterPinterestSave分享0 With over 2,000 extrasolar planets found around nearly as many stars, there’s still no place like home.“Why aren’t we finding other planetary systems like our own?” PhysOrg asked.  While the menagerie of planets discovered by the Kepler spacecraft is exotic and curious, it primarily shows that our earth escaped certain death.Most planetary systems found by astronomers so far are quite different than our own. Many have giant planets whizzing around in a compact configuration, very close to their star. An extreme case in point is a newly found solar system that was announced on October 15, 2012 which packs five—count ’em—five planets into a region less than one-twelve the size of Earth’s orbit!An attending scientist at the American Astronomical Association’s Division of Planetary Sciences (DPS) meeting commented, “If we can understand this one, hopefully we can understand how these types of systems form and why most known planetary systems appear different from our own solar system.”  Now, though, it is not clear.  Most planets orbit very close in, but our sun’s planets are widely spaced.The fact that almost all solar systems found so far are so different than our own has astronomers wondering if we are, in fact, the oddballs. A study from 2010 concluded that only about 10 – 15 percent of stars in the Universe host systems of planets like our own, with terrestrial planets nearer the star and several gas giant planets in the outer part of the solar system.This might be a selection effect based on what our instruments are capable of detecting, but the discovery of so many close-in planets is sending theorists back to the drawing board.There are several theories about the formation of the large planets in our outer solar system which involves the planets moving and migrating inward and outward during the formation process. But why didn’t the inner planets, including Earth, move in closer, too?Fact is, “We don’t know why this didn’t happen in our solar system,” the spokesperson said.  It’s going to require “a new generation of theories to explain why our solar system turned out so differently.”Several science sites like National Geographic gawked at another oddball system that finds a planet orbiting a four stars, leading to inevitable comparisons with Tatooine of the Star Wars mythology.  The real story is that the planet also “challenges conventional notions of how planets form,” an astronomer said.  “The discovery of these systems is forcing us to go back to the drawing board to understand how such planets can assemble and evolve in these dynamically challenging environments.”Update 10/17/2012:  An earth-size planet has been found! –but you wouldn’t want to visit there. said that the earth-size planet orbits a member of the Alpha Centauri system closer than Mercury orbits the sun, making it a “hellish, lava world.”  On Oct 18, used the opportunity of this discovery to list some of the requirements (and desirements) for a planet to be hospitable for life.This is not what the astrobiologists, astronomers and modelers expected.  Migration was brought into the nebular hypothesis in response to discoveries, not as a prediction of those discoveries.  What have “conventional notions” done for you lately?  The sight of experts rushing back to their drawing boards implies that planetary evolution theory is in a mess.  Hot Jupiters abound, requiring them to posit rapid migration toward the star.  Who knows how many fell in?  On the way in, if indeed they migrated, they would have sent rocky planets with interior orbits careening out of their stellar systems.Another problem posed by the hot Jupiters and closely-orbiting rocky planets is the realization that planets had to form much more quickly than the nebular hypothesis allowed.  Instead of slow “core accretion,” theorists invented new ideas out of whole cloth, like “disk instability,” trying to get gas giants to form in decades or centuries instead of millions of years, to allow them time to clear out their orbital debris before the nebula dragged them inward.  This is another example of how inept astronomers are at explaining planets despite their admirable skill at observing and describing them.   Virtually every planet in our solar system surprised them: none of them fit the predictions of the nebular hypothesis and billions of years.Meanwhile, here our earth sits, safe inside our sun’s habitable zone, as most of us pay these cosmic billiard games little mind.   Instead of thanking your lucky star, you might try thanking your Creator.last_img read more

Microsoft Execs Flock To Amazon And Red Hat

first_imgIT + Project Management: A Love Affair Tags:#Amazon#Azure#cloud#Microsoft#mobile#Open Source#paas#Red Hat#Windows Phone Matt Asay Microsoft may be a distant runner-up to iOS and Android in the smartphone race, and still lags Amazon EC2 in the cloud wars, but executives from the Windows Phone and Azure divisions aren’t hurting for respect. In the past week, senior Microsoft executives have joined disruptive challengers in the mobile and cloud markets, suggesting that Microsoft’s brainpower isn’t lacking, even if its market share is.The first executive departure was Charlie Kindel, the former Microsoft executive who managed developer outreach for Windows Phone, who actually left Microsoft nearly two years ago but just now found his way to Amazon. While it’s still anyone’s guess as to what Kindel will be doing at Amazon – given his past role with Windows Phone, some are mooting the possibility that he will be helping build out an Amazon phone – this is becoming a bit of a habit for Windows Phone executives to leave for Amazon.After all, just last year Brandon Watson, also from the Windows Phone developer outreach team, left for Amazon. In his case, Watson joined Amazon to help on the Kindle cross-platform team.Nor is it just the Windows Phone team that has been leaking.Today Red Hat announced that it had snagged Radhesh Balakrishnan, Microsoft’s Azure chief for Asia-Pacific, to run its virtualization efforts, including OpenShift, Red Hat’s open-source PaaS offering. If Red Hat were to borrow from any competitor to steal a march on VMware in the virtualization market, or Amazon in the cloud market, Microsoft was a great place to look.After all, Microsoft has been cutting into VMware’s virtualization market share for years, and Azure has become a solid #2 to Amazon, as a recent Forrester survey indicates: 3 Areas of Your Business that Need Tech Now Cognitive Automation is the Immediate Future of… Massive Non-Desk Workforce is an Opportunity fo… Related Posts One way to look at this is that Microsoft is hemorrhaging talent and must be a sinking ship. But I think this would be an incorrect reading. After all, though Microsoft is late to both the cloud and mobile parties, it’s making progress in both, and continues to own the affections of CIOs. No, I think the better interpretation is that for all Microsoft’s execution issues, it continues to have a bevy of super-smart employees. Amazon and Red Hat certainly seem to think so. And for every Microsoft executive that leaves, there are many more who are choosing to stay. If anything, these departures say little about Microsoft’s fortunes and instead simply indicate that Amazon and Red Hat may offer exciting options of their own. While it’s tempting to assume that executive departures are a clear sign of a company’s struggles, reading the tea leaves in this way would put Apple, Facebook and Google, among others, in serious jeopardy.Most people would love to have that kind of “jeopardy.”Image courtesy of Shutterstock.last_img read more

Understanding Color Rendering Index with LEDs

first_imgThe Color Rendering Index can help you get the best LED color reproductions.Cover image via Shutterstock.The Color Rendering Index (CRI) is the go-to measure when speaking about the quality of different sources of light; the CRI rating can have a big effect on the reproduction of colors in your video shoot, so it’s important to keep in mind when selecting and using lights. However, do not confuse it with “color temperature,” which describes other aspects of light.What Is CRI?The CRI describes how accurately a light source reproduces colors on a scale from 1 to 100. The lower the number, the worse the reproduction of the color. Some spectrometers, such as the Sekonic C-700 or Gossen Mavospec, can read and display the CRI of a metered light source. That makes them brilliant tools for comparing different manufacturers and sources when working in videography and photography. However, these meters may be too expensive for many shooters, and while you can rent them, they aren’t a necessity on set. (Manufacturers will often list the CRI ratings of their lights on their websites.)As a general rule, any source with a CRI rating of 90 or above will faithfully render colors. Most good tungsten sources will have a CRI rating of 90 or above — often over 95. Sunlight will have the best CRI rating of all.The following is an example of the CRI rating of sunlight.Notice that the rating divides into eight different colors. This is a problem when using the CRI rating to analyze manufactured light sources — the sampling is only an average of eight colors. It is possible for a light to have a good CRI rating in regards to these eight colors, but it could still have a low rating beyond these color samples. It may not score highly for a deeply saturated red, for example, which would lower the rendering rating. Some LED lights can show large variations in different parts of the color spectrum when compared to tungsten or daylight; therefore, it is necessary to look beyond the standard eight colors when analyzing LEDs in particular.Beyond CRIThe Television Lighting Consistency Index (TLCI) is an improvement upon the CRI rating. It samples twenty-four colors, and it is more reliable for analyzing how light renders on a camera’s sensor. However, this index was initially for broadcast television cameras and arguably does not account for single-chipped cameras that are more common in the film and video industry.The Extended CRI rating (sometimes referred to as Special CRI) is the most useful for the majority of film and video applications. It is also what the Sekonic C-700 will display. The Extended CRI rating adds R9 – R15 colors to the standard CRI samples — including, most importantly, R9 Saturated Red, R13 Skin Color (Light), and R15 Skin Color (Medium), which are all difficult colors to faithfully reproduce.The image below shows an example of the Extended CRI rating of sunlightThis is as close as you are likely to get to a perfect CRI rating on a spectrometer on set. It shows that even sunlight is not getting a full 100 rating. This could be due to any number of reasons — even bounced light affecting the reading. However, it is a very good gauge of the reliability.Cheap LEDsIf we now look at a cheap LED, you will see a big difference.There are many areas of the color spectrum that this light will not render correctly. This would most likely result in odd hues in skin tones or other color casts within the image that are unexpected, undesired, and uncontrollable. However, the manufacturer could justifiably give this light source a CRI rating of 83. This is not an excellent rating but, at first glance, should at least imply a decent rendering of most colors. If this light source is priced well, it may be a viable alternative to more expensive options. Now the importance of the Extended CRI rating becomes more relevant. One can’t use sources such as this and expect faithful color reproduction across the spectrum. You would likely see similar inconsistencies with other cheap sources, most commonly with halogen and fluorescent lights.So, if you are looking to save money when renting or buying LEDs, halogens, or fluorescents, then always start by checking for an Extended CRI rating or a TLCI rating. If you can’t find one, consider renting a spectrometer and checking the rating yourself.Do you have tips for assessing lighting sources? Let us know in the comments.last_img read more

Stones hurled at MP CM Chouhan’s vehicle in Sidhi

first_imgMiscreants threw stones on the vehicle carrying Madhya Pradesh Chief Minister Shivraj Singh Chouhan, who is touring the State ahead of Assembly elections, in Churhat area near Sidhi district, a police official said. Mr. Chouhan was not hurt in the incident, Churhat Police Inspector Ram Babu Choudhari told PTI over phone. He did not give any more information, saying he was busy discharging his duties at a public meeting of the chief minister in the district. Stones were hurled at Mr. Chouhan’s vehicle in Churhat area — which is the Assembly constituency of Leader of Opposition Ajay Singh, Madhya Pradesh BJP spokesman Rajnish Agrawal said.Churhat is about 25 km from the district headquarters. Later addressing a public meeting in the district as part of his Jan Ashirwad Yatra, Mr. Chouhan dared Mr. Singh to come in the open and fight with him. “Ajay Singh, if you have strength come in open and fight with me,” he said.“I am physically weak but I won’t be bogged down by your deeds. People of the state are with me,” he added. In a press release, Mr. Singh said no Congressman was involved in the stone-pelting incident. He said his party does not follow the culture of violence. “I suspect that it was a well thought and hatched conspiracy aimed at defaming me and people of Churhat,” he added. Mr. Chouhan is touring the State in a bus modified as a chariot.last_img read more
