Wrong Again: Planetologists Embarrassed

first_img Sun:  The Genesis spacecraft was supposed to tell planetary scientists how the rocky planets formed by gathering particles from the solar wind and comparing its isotopes with those of the planets.  Theory assumed that the earth, having formed from the primordial nebula surrounding the parent star, would have similar isotopic signatures to the sun.  Analysis of the data was seriously delayed due to the catastrophic crash landing of the capsule in 2004.  Results were just published in two papers in Science.1,2 Specifically, the sun’s particles were found to have much more oxygen-16 and dramatically less nitrogen-14 than is found in Earth’s atmosphere.  Commenting on this surprise, Science Daily titled its report, “Sun and Planets Constructed Differently Than Thought, NASA Mission Suggests.”     Commenting on these papers in the same issue of Science,3 Robert Clayton said, “The principal conclusion from the studies of McKeegan et al. and Marty et al. is that the Earth was not constructed from average solar system materials.”  A hastily-concocted scenario involving self-shielding of isotopes was put forth to explain the discrepancy, but reminded readers, “it’s not a certainty.”  Bernard Marty, lead author of one of the papers, said in Science Daily, “These findings show that all solar system objects including the terrestrial planets, meteorites and comets are anomalous compared to the initial composition of the nebula from which the solar system formed.  Understanding the cause of such a heterogeneity will impact our view on the formation of the solar system.”  Another article on Science Daily put a happy face on the problem with this headline: “Solar Wind Samples Give Insight Into Birth of Solar System.” Enceladus:  Saturn’s geysering moon Enceladus has become a prima donna of the solar system with its dramatic performances.  The Cassini spacecraft recently made another pass through the geysers at close range and sampled some of the particles (see Science Daily, Physorg).  New counts of sodium and potassium particles are swinging opinion in favor of a liquid-water ocean down deep.  This, predictably, stimulated rhetoric about the L-word life, as Richard Kerr shamelessly shouted in his headline in Science last week,4 “Enceladus Now Looks Wet, So It May Be ALIVE!”     The real headline, though, is that water was unexpected at this tiny moon the diameter of Arizona.  In another article on Science Daily, Nicholas Altobelli lamented, “Enceladus is a tiny icy moon located in a region of the outer Solar System where no liquid water was expected to exist, because of its large distance from the Sun.”  He, too, quickly changed the subject to life: “This finding is therefore a crucial new piece of evidence showing that environmental conditions favourable to the emergence of life may be sustainable on icy bodies orbiting gas giant planets.”     The life word cannot mask the challenge that Enceladus makes to claims that it is 4.6 billion years old.  A new paper in Icarus emphasizes the problem: Chin and Nimmo calculated that obliquity tides do not significantly heat Enceladus. Any heating would be around a thousand times too small as a heat source for the moon’s powerful geysers.5     Incidentally, readers may wish to gaze upon a dazzling close-up of the tiny moonlet Helene taken by the Cassini orbiter on June 18 ( Comets:  It wasn’t that many years ago that scientists were telling the public that comets were dirty snowballs from the pristine outer reaches of the solar system nudged in toward the sun by passing stars.  Several missions to real comets, including Halley, Borrely, and Tempel 1, have shown that idea to be simplistic.  Minerals requiring high temperatures for their formation were found from the Deep Impact experiment, and Stardust found similar anomalous materials, calling for radical revisions of theories.    Now enter Comet Hartley 2, visited last November on Deep Impact’s extended mission, nicknamed EPOXI.  Natalie Wolchover’s headline on Live Science tells all: “Quirky Comet Hartley 2 Confounds Theories on Early Solar System.”  This oddball comet is not only hyperactive and spinning rapidly (contrary to expectations), it has different levels of carbon monoxide on the two ends of its peanut shape, spits off large chucks of ice, and has CN values that varied dramatically during the observation period.     The summary and conclusions of a paper in Science6 revealed face-saving rhetoric: “Comet 103P/Hartley 2 differs in many ways from 9P/Tempel 1 and is an ideal example of hyperactive comets, ones that produce more H2O per unit time than should be possible by sublimation from the small surface area of their nuclei.”  This seems to be saying that the comet is an ideal example of an impossible object.  The description continued, calling attention to other unexected differences with other comets, ending, “A large anomaly in CN, too slow to be called an outburst, is unexplained.” In most careers, being wrong too often is grounds for dismissal.  False prophets in ancient kingdoms were stoned or shamed out of town.  Only in science, it seems, can experts consistently get it wrong, and not only keep their jobs, but be highly esteemed as experts.  Among the guiltiest of the lot are planetary scientists, whose predictions have been consistently wrong for almost every planetary body studied since the dawn of the space age.  Their orbital mechanics is solid; they do get their spacecraft to arrive at the right place at the right time with uncanny accuracy.  But what the missions reveal is often completely different from what scientists had told the public they expected to find.  This has been true of Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, comets, asteroids, and most of the moons of the solar system, where hasty revisions have had to be made after spacecraft data falsified the predictions.  Here are some recent examples of  “theory fail” in planetary science. 1. Marty et al, “A 15N-Poor Isotopic Composition for the Solar System As Shown by Genesis Solar Wind Samples ” Science, 24 June 2011: Vol. 332 no. 6037 pp. 1533-1536, DOI: 10.1126/science.1204656. 2. McKeegan et al, “The Oxygen Isotopic Composition of the Sun Inferred from Captured Solar Wind,” Science, 24 June 2011: Vol. 332 no. 6037 pp. 1528-1532, DOI: 10.1126/science.1204636. 3. Robert Clayton, “Planetary Science: The Earth and the Sun,” Science, 24 June 2011: Vol. 332 no. 6037 pp. 1509-1510, DOI: 10.1126/science.1206965. 4. Richard A. Kerr, “Planetary Science Enceladus Now Looks Wet, So It May Be ALIVE!”, Science, 10 June 2011: Vol. 332 no. 6035 p. 1259, DOI: 10.1126/science.332.6035.1259. 5. Chin and Nimmo, “Obliquity tides do not significantly heat Enceladus,” Icarus (article in press June 2011), doi:10.1016/j.icarus.2011.06.007. 6. A’Hearn et al, “EPOXI at Comet Hartley 2,” Science, 17 June 2011: Vol. 332 no. 6036 pp. 1396-1400, DOI: 10.1126/science.1204054. We want to make it clear that this is not a criticism of scientific discovery, but of scientific explanation.  The thousands of scientists, engineers and technicians who make these spacecraft work are to be forever commended for bringing to earth, in our lifetimes, a hugely impressive treasure trove of new data about the solar system.  This includes the technicians who tirelessly worked for years to save the delicate particles from the Genesis mission, and all the others who have wrought success after success with Stardust, Cassini, Deep Impact, and all the other heroic missions of discovery.     Explanation, however, is a completely different thing.  Because of their evolutionary old-age assumptions, planetary scientists expected to find things in keeping with their assumptions.  When they didn’t, should they be praised?  Numerous findings have falsified their evolutionary picture.  Their web of belief has had to be reinforced with steel to protect the all-important central assumption of the A.S.S. (age of the solar system, 4.6 billion years), the Law of the Misdeeds and Perversions that Cannot Be Altered.  Don’t be distracted by their red herrings about life.  The Baloney Detector pointer dog is no respecter of persons: ’You were wrong!” he barks.(Visited 52 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

NCGA, ASA Testify at Senate Hearing on Ag Industry Consolidation

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Regulatory barriers facing agriculture are a major driver of agriculture industry consolidation, National Corn Growers Association Chief Executive Officer Chris Novak testified Tuesday at a Senate Judiciary Committee hearing on consolidation and competition in the U.S. seed and agrochemical industry. Novak testifyied on behalf of both the National Corn Growers Association and the American Soybean Association.“Domestic regulatory hurdles for crop protection chemicals and delays in international approvals for new seed traits represent significant barriers to market entry. These barriers slow down innovation and drive up the cost of seed and chemicals. The process of developing and testing new products, and then securing regulatory approval to bring them to market, requires a substantial amount of time and money. As a result, fewer and fewer companies have the resources to be players in the market. This trend toward consolidation will continue unless and until Congress addresses these regulatory hurdles,” Novak will testify.Together, NCGA and ASA represent more than 500,000 corn and soybean farmers nationwide, and they have a direct interest in ensuring a competitive marketplace for crop production inputs. Earlier this year, NCGA and ASA joined forces to conduct an analysis of a recently announced merger and ensure their members’ best interests were represented in conversations with the Department of Justice.In written testimony submitted to the Senate Judiciary Committee for the hearing, NCGA and ASA argue that a competitive marketplace is measured by more than the number of competitors, but also their size and relative ability to compete.“True competition is not based solely on the number of players within a given market. Strong competition can result from having several evenly-matched companies fighting for market share within the seed, chemistry and trait development markets,” the written testimony states.NCGA and ASA call on government and industry to work together to maintain farmers’ access to tools and technology.“We’ve seen a significant decline in the number of small-to-medium sized family farms. Fewer farmers means that the agribusiness industry that supports the farm community has fewer customers—resulting in consolidation beyond the farm gate. The speed at which the industry continues to consolidate, and the tenuous state of our farm economy, dictate that we work diligently to ensure that our farmers will still have access to a range of technologies without suffering higher costs,” the written testimony states.Click here to read the full written testimony.last_img read more

Google’s New Ad Server Goes After the Little Guy

It knows what type of car you drive from that time, last year, when you looked up the where you could find a cheap set of tires. It knows that you like Mexican food from all the times you’ve looked on Google Maps. And Google knows how to leverage this type of information with services like Google AdWords, AdSense, and DoubleClick Ad Exchange but now it’s moving into what it’s calling “the next generation of ad serving” – a simplified, streamlined ad server.While Google currently has the upper hand in the battle, it’s starting to look more and more like Google and Facebook are about to duke it out in the advertising arena. And who will they be battling over? The little guy.Google’s latest move in the advertising sphere replaces DoubleClick DART and Google Ad Manager with DoubleClick for Publishers, an ad management system meant to simplify the more complex aspects of managing ad space.According to an article on PaidContent, this latest move by Google “involves the promise of greater simplicity as it aims for smaller publishers”. DoubleClick for Publishers offers a simple, free version of DFP for small businesses and another (not free) for larger websites – likely customers of DoubleClick DART.The new service offers a redesigned interface, more detailed reporting, algorithms to automatically improve ad performance and a public API to allow for third-party apps to use the DFP system. DFP will allow its users to perform a number of functions, from running different ads at different times, according to when they best perform, to mixing and matching different priced ads to various page locations. We think that the increased focus on small businesses is a growing trend in online advertising, as we just saw with Facebook announcing last week that it would begin accepting PayPal for advertising. It seems that many of these big companies are realizing that they may be missing out on innumerable revenue streams from small businesses by making the task of advertising daunting and complicated. A dollar is a dollar, after all, and increasing accessibility while reducing confusion should only increase the number of dollars coming in. 8 Best WordPress Hosting Solutions on the Marketlast_img read more
