Astronomical Theories Totally Wrong and Upside Down

first_imgFrom the planetary scale to the cosmic scale, astronomers are throwing away textbooks.Wrong About Planets‘Totally Wrong’ on Jupiter: What Scientists Gleaned from NASA’s Juno Mission (Space.com). The Juno mission has brought earthlings their first images of Jupiter’s poles, and new estimates of processes deep inside the giant planet. Here’s what this article says:Before NASA sent its Juno spacecraft to explore Jupiter, astronomers were “totally wrong” about much of what they thought they knew about the planet, the mission’s principal investigator, Scott Bolton, said during a lecture here at the 231st meeting of the American Astronomical Society on Tuesday (Jan. 9)….“Our ideas were totally wrong about the interior structure, about the atmosphere, [and] even about the magnetosphere,” Bolton said. Astronomers believed that Jupiter had either a very small and dense core, or perhaps no core at all. But data from Juno revealed that Jupiter has an enormous, “fuzzy” core that might be partially dissolved. This discrepancy between scientists’ expectations and the data suggests that there’s a lot we still don’t know about giant gas planets, he explained….Jupiter South Pole from Juno (NASA/JPL)Juno is the first space mission to get a good look at the poles, and the mission’s scientists did not expect them to look as weird and chaotic as they do, Bolton said. “Had someone shown me a picture of just the pole 10 years ago, I never would have guessed it was Jupiter.”While scientists and astronomers have been scratching their heads over all these new groundbreaking discoveries enabled by the Juno spacecraft, the photographs Juno has taken of Jupiter have been similarly mind-boggling, Bolton said. Juno’s raw images, taken by the spacecraft’s JunoCam, are available online for citizen-scientists to download and process, and people have helped to create the most amazing images of Jupiter the world has ever seen. “I’m not sure that anybody on my team was ready for Jupiter to look like that,” Bolton said. “We were just startled.”Wrong About ExoplanetsPlanets around other stars are like peas in a pod (Science Daily). The Kepler Mission had already forced revision of astronomical predictions that planetary systems around other stars would resemble our solar system. Now, a new survey of 909 planets in 355 stellar systems, led by Lauren Weiss at the University of Montreal, shows that exoplanets tend to be regularly spaced. The findings require new ideas, invoking unobserved past interactions, to explain why our solar system is so different.“The planets in a system tend to be the same size and regularly spaced, like peas in a pod. These patterns would not occur if the planet sizes or spacings were drawn at random.” explains Weiss….Regardless of their outer populations, the similarity of planets in the inner regions of extrasolar systems requires an explanation.Wrong About StarsNature article turns theory of stellar evolution upside-down (Phys.org). Study of a white dwarf not only challenges theories about these specific objects, thought to be the end points of stellar evolution, but of stellar evolution theory itself. White dwarfs are thought to be the end products of 97% of stars in the universe. This upset was published by “Nature, one of the world’s top science magazines,” the article notes.This week, Nature published an article that could challenge the theory of stellar evolution.“I think that, over the coming months, stellar astrophysicists will have to redo their calculations,” said Gilles Fontaine, a physics professor at Université de Montréal and one of the authors of the article, titled “A large oxygen-dominated core from the seismic cartography of a pulsating white dwarf.”…When examining the star, located at the edges of the Cygnus and Lyra constellations, the researchers discovered that its carbon and oxygen core was twice as big as the theory predicted. “This is a major discovery that will force us to re-evaluate our view of how stars die,” said Fontaine. “That said, more work must be done to confirm whether this observation holds true for other stars. It may just be an anomaly.”Wrong About the Universe‘Serious gap’ in cosmic expansion rate hints at new physics (BBC News). One of the winners of the Nobel Prize for Physics in 2011, Adam Riess, is having doubts about the measurements that led to his award. He may have to invent a new particle to close the gap.A mathematical discrepancy in the expansion rate of the Universe is now “pretty serious”, and could point the way to a major discovery in physics, says a Nobel laureate.The most recent results suggest the inconsistency is not going away….What this all suggested, he said, was that the Universe is now expanding 9% faster than expected based on the data – a result he described as “remarkable”.One way to bridge the divide is to invoke new phenomena in physics.The new particle might be a “sterile neutrino,” the article guesses. “Another possibility is that dark energy behaves in a different way now compared with how it did in the early history of the cosmos.” Would that ad hoc suggestion not lead to another conundrum about fine-tuning, leading to wonder about how humans live in a privileged time when the earth is habitable and we can see a universe filled with stars?Historical science is fun. You can be totally wrong, change your story, invoke unseen phenomena, and claim you are providing “understanding” of reality. And the media and public will believe you and let you keep your job.(Visited 1,656 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

How the Cloud Flattens Formats and Changes the Way We Create and Edit Documents

first_imgalex williams Why Tech Companies Need Simpler Terms of Servic… Related Posts Tags:#Analysis#cloud#cloud computing A Web Developer’s New Best Friend is the AI Wai…center_img Top Reasons to Go With Managed WordPress Hosting It’s a gradual move that we see people make to the cloud. It may seem slow at times but it is happening. What moves it along are the incremental changes to applications that make the services just a little bit easier to use.Here are three news items from this week that demonstrate how this shift is occurring. These news items have a common thread. All represent how Web operating systems (OS) flatten document formats for universal use and collaboration.Google Docs Supports 12 New FormatsHeavy Google Docs users know that not all file types can be imported into Google Docs. There’s always some way around the problem but the formatting is usually lost in some manner.Google Docs now supports 12 new file types that should lessen the issue to some extent.The new file types include:Microsoft Excel (.XLS and .XLSX)Microsoft PowerPoint 2007 / 2010 (.PPTX)Apple Pages (.PAGES)Adobe Illustrator (.AI)Adobe Photoshop (.PSD)Autodesk AutoCad (.DXF)Scalable Vector Graphics (.SVG)PostScript (.EPS, .PS)TrueType (.TTF)XML Paper Specification (.XPS)Turn Your Tablet into a PCThis week, the Laptop Magazine blog reviewed a service designed for the new Honeycomb tablets. Quickoffice for Honeycomb uses the wide screen capabilities of the tablet as it runs the Android 3.0 operating system.The Quickoffice service abstracts the formats in Microsoft Office, allowing documents to be edited on mobile devices. A lot of talk at the Mobile World Congress was about the Web operating system for mobile devices. My view is that formats are an example of the breakdown in hierarchical systems that has lead us to the new Web operating systems such as Hewlett-Packar’s WebOS and the Google Chrome OS.The Laptop blog reviews a few of the capabilities that come with Quickoffice:For example, the file manager which appears when you first launch the app is a three-paned menu with a list of both local and cloud-based storage drive son the left, a list of files and folders in the center, and the files in the currently selected folder on the right.In the Quickpoint presentation editor, a panel on the left allows you to scroll through the list of slides in your presentation and reorder them by tap and dragging. In the Quickword document editor, you can see a list of thumbnails of the next and previous pages while you finger scroll and a context menu in the top bar changes to allow contextual search or formatting when you highlight a piece of text. The Quickpoint spreadsheet editor is also impressive, as it includes 140 formulas built in and the ability to handle multiple worksheets.Crocodoc Launches HTML5 ViewerCrocodoc launched an embeddable HTML5 document viewing and collaboration tool this week. The HTML5 viewer replaces its Flash-based viewer. The company is seeking to disrupt Adobe in the PDF editing and document collaboration space.Adobe is a classic example of a company that can be disrupted in this new innovation cycle. Crocodoc is further extending its reach by offering a new partner program. Yammer, for instance, will be integrating the Crocodoc service into its product.Formats for a Desktop AgeLooking at these announcements, you get the sense of what happens when older technologies become less useful. We talk a lot about the rate of change and how it takes longer than we think for trends to take footing. The online editing space has gone through a number of iterations over the past few years. In the process, the usefulness of services like Google Docs has lead to a shift that is affecting millions of people who just need an easier way to get things done.We will see formats flatten to fit the needs of users who want the simplicity of the Web OS. We’re in a different time now. It’s more about group collaboration than the singular task of creating documents for the purposes of one-way communication. 8 Best WordPress Hosting Solutions on the Marketlast_img read more
