Our moon is unique in the solar system. Just the right size and just the right distance, it is positioned to stabilize the tilt of Earth’s axis, providing stable seasonal cycles. Science lacks data so far to know just how unique the Earth-moon relationship in a habitable zone is among other stellar systems. We know from the planets of our own solar system that moons come in all sizes, from tiny Deimos to massive Titan, and orbit in apparently arbitrary radii from their host planets. What astrophysicists can do is predict what would happen on earth if things were different. That’s what one scientist did. Another discovery could change the view of the moon’s surface being unaltered for billions of years.PhysOrg reported a thought experiment by Neil F. Comins, author of a book entitled, What If the Earth Had Two Moons? (see title on Amazon.com). First, consider why we should be glad to have just one:Our Earth-Moon system is unique in the solar system. The Moon is 1/81 the mass of Earth while most moons are only about 3/10,000 the mass of their planet. The size of the Moon is a major contributing factor to complex life on Earth. It is responsible for the high tides that stirred up the primordial soup of the early Earth, it’s the reason our day is 24 hours long, it gives light for the variety of life forms that live and hunt during the night, and it keeps our planet’s axis tilted at the same angle to give us a constant cycle of seasons.A second moon would change that.Here’s he says would happen if Earth were to capture a second moon he names Luna:Luna’s arrival would wreak havoc on Earth. Its gravity would tug on the planet causing absolutely massive tsunamis, earthquakes, and increased volcanic activity. The ash and chemicals raining down would cause a mass extinction on Earth.Comins, clearly an evolutionist because of his reference to the primordial soup icon, thinks that after a few weeks, things would settle down on Earth for life to evolve again. Nocturnal animals, if they emerged, would have to adjust to brighter light at night. Should humans arrive on such a world, there would be no rhymes of ancient mariners: tides would be measured in thousands of feet, making beachfront life and cruises nearly impossible. “The habitable area of Earth, then, would be much smaller.”But Earth’s troubles would not end there. Eventually, the two moons would collide, undoubtedly raining debris onto the Earth, resulting in another mass extinction. Ever the optimist, he ends, “The end result would be one moon orbiting the Earth, and life another era of life would be primed to start.”Space.com reported on a NASA study that should cause us to be thankful for our global magnetic field. The energy of coronal mass ejections is sufficient to “sandblast” the moon’s surface. Earth is protected from the rain of terror from the sun, consisting of a “ billion tons of plasma that tear through space at a blistering pace of up to a million miles per hour in a cloud many times the size of Earth,” because the charged particles get deflected around our world or hit the atmosphere at the poles, producing little more than inconvenience to electronic gear in the worst case, or beautiful auroras to admire.The moon and Mars, however, lack the protection of a global magnetic field. That may be why Mars has such a thin atmosphere – whatever it had before has been eroded from the onslaught of the solar wind. What’s new about the NASA study is the finding that the proportion of charged helium rises from 4% to 20% in coronal mass ejections (CMEs). Because of their greater mass, helium ions can sputter away ten times more material from the lunar surface. A NASA scientist at Goddard said, “”The model predicts 100 to 200 tons of lunar material — the equivalent of 10 dump truck loads — could be stripped off the lunar surface during the typical two-day passage of a CME.”Although the article did not explore the consequences over the assumed lifetime of the moon (4.5 billion years), it would seem, since almost every part of the moon except possibly at some spots near the poles is exposed to “the wrath of the sun,” that the lunar surface would have been subject to considerable reworking by CMEs over that time.Exercise: Calculate the mass loss and change of appearance expected of the lunar surface for an old moon subjected to sputtering by CMEs, and whether the calculation matches what was observed by the Apollo astronauts. Take into account the average frequency of CMEs striking the moon in 4.5 billion years. The delicate balance of the Earth-moon system is a prediction of intelligent design. For evolutionary theory, it is a lucky happenstance. In science, prediction generally has more value than saying “Lucky stuff happens sometimes.” For an explanation of our moon, therefore, the edge should, therefore, be given to intelligent design instead of evolution. We’ll let interested researchers explore the age implications of continual bombardment of the moon by CMEs. At first glance it seems doubtful that removal of dump truck loads of material for billions of years would leave the lunar surface the way the Apollo astronauts found it.If Comins thinks that the Earth would be primed for life to start after two catastrophic extinctions, well, we have some beachfront property on Titan to sell cheap, stocked with cupboards of primordial soup.(Visited 19 times, 1 visits today)FacebookTwitterPinterestSave分享0
Share Facebook Twitter Google + LinkedIn Pinterest The Ohio AgriBusiness Association’s 2018 Industry Conference provided extensive education and networking opportunities for agribusiness professionals. The topics covered at the event included economic outlook, crisis communication, hiring challenges, weed and insect management, trade, decision making, nitrogen management, technology, risk management, transportation, cover crops and more.“We’re up this year with attendance, which we are pleased about. We had over 300 people. It boils down to providing good topics, good speakers and creating a good venue for networking,” said Chris Henney, OABA president and CEO. “We are hearing about dicamba and water quality issues like everyone else, but some specific issues in agribusiness are mergers and acquisitions. We are seeing that at the national level but also at every level — state, regional and local. Another real issue is succession planning. There are a lot of baby boomers retiring now or are poised to retire soon. How are we filling those voids?”In addition to the broad array of topics covered, attendees got to hear from Dave Rife, owner of White Castle, who talked about the “Power of Passion” for the family-run fast food hamburger business. Rife talked about treating his 10,000 employees like an extended family in the nationwide restaurant chain and emphasized service to customers and building the brand.The 2018 OABA Awards Initiative recipients were recognized as well including Andrew Gladden, with Luckey Farmers for his Achievement as an Emerging Leader, and Anne Cook, with The Andersons, Inc. for Excellence in Safety & Stewardship. The closing session for the event featured CEOs from across Ohio — George Secor, Sunrise Cooperative; Brad Rivers, Novus Ag; and Phil Farmer, FLM Harvest — in a discussion of how they hire and train employees. They shared many insights about the value of a good internship program, understanding the generational differences in the work place and working find and hire qualified employees.OABA also announced the newly elected members to the Board of Directors:Representing the Agrichemical industry: Nick Franks, Tyler Grain & Fertilizer Co.Representing the Feed industry: Anne Staugler, Big K Mills, Inc.Representing the Grain industry: Scott Thibaut, Consolidated Grain & Barge Inc.Representing the Members-at-Large: Jean Bratton, Centerra Co-op and Greg Logue, The Andersons, Inc.In addition to new members, the Board of Directors has new leadership for 2018-2019. Jackie Seibert of United Equity, Inc. was elected to serve as Vice Chairwoman. Andy Swerlein of Luckey Farmers Inc. transitions from his role as Chairman to Past Chairman. Nathan Louiso of Axis Seed will serve as Chairman of the Board.“I have been involved with OABA for around 10 years and lot of people don’t know that I didn’t grow up on the farm,” Louiso said. “That puts me in a unique position as we look to our membership in the future and the employees of our memberships. I think we need to start reaching out to non-traditional members that maybe didn’t grow up on a farm but that may have an interest in agriculture. Our industry isn’t a special fraternity that requires you to have grown up on a farm.“I think we need to look at things in a different manner given the demand for our industry. All you need is an interest in agriculture and a strong work ethic. New technology is a perfect example. Big data and precision ag has taken off so fast. I don’t think a person necessarily has to come from a farm to be in that space.”The OABA Board of Directors consists of 15 individuals who represent various segments of the agribusiness industry in Ohio, including feed, seed, fertilizer, grain and agrichemical sectors. Board members are elected by OABA member companies to three-year terms and can serve two terms.“I would encourage people to be involved,” Louiso said. “Start on a committee and give back.”The complete list of Board members is:Chairman: Nathan Louiso, Axis SeedVice Chairwoman: Jackie Seibert, United Equity, Inc.Past Chairman: Andy Swerlein, Luckey Farmers, Inc.Jean Bratton, Centerra Co-opEd Burtch, Burtch Seed Company, Inc.Scott Crowder, Central Ohio Farmers Co-opNick Franks, Tyler Grain & Fertilizer Co.Grant Gates, Morral Companies, LLCBrad Johnson, Kalmbach Feeds, Inc.Greg Logue, The Andersons, Inc.Robert Mullen, NutrienAnne Staugler, Big K Mills, Inc.Scott Thibaut, Consolidated Grain & Barge, Inc.John Ward II, ABIS/J.H.

Tags:#events#start Why Tech Companies Need Simpler Terms of Servic… Top Reasons to Go With Managed WordPress Hosting Related Posts A Web Developer’s New Best Friend is the AI Wai… The talk of the venture capital and entrepreneurial towns these days is the Open Angel Forum which after its second event in Boulder, Colorado is now announcing two more events in New York and San Francisco. Brainchild of Jason Calacanis, the Open Angel Forum (OAF) is an opportunity for startups to get face-time with active big-time venture capitalists and angel investors – all for the low, low price of free. As we mentioned back in January following the debut event in Los Angeles, the OAF was formed out of frustration over events and investors which charge startups to present their companies – the so called “pay to pitch” debate. In a true example of making the best of a bad situation, the OAF has created a place where the both the best startups with the most potential can meet the top VCs and angels who are looking to invest.At last week’s Boulder event, six startups from over 100 applicants were chosen to meet with twenty hand-picked VCs, and all seemed to walk away from the event satisfied and thrilled by the event. In fact, all six companies – FaceFile, Grogger, TeamSnap, Odojo, Decasun and Kijubi – have all since blogged about their experiences. “This fairness to us and others presenting plus the rule to only allow active investors makes OAF the best event we’ve attended since we started two years ago,” writes Beckie Mostello of FaceFile. “The couple of hours we just spent with the OAF Forum tonight in Boulder, Colorado was the most valuable investment-oriented experience we have yet to be involved in,” echoes Dave DuPont of TeamSnap.The Open Angel Forum will keep its current momentum at full-speed-ahead as it rolls into San Francisco in March with a little help from local hosts Kevin Rose and Chris Sacca. The following month, Calacanis and Co. will travel to the east-coast for OAF New York, hosted by Brian Alvey and Charlie O’Donnell.Mark Solon, an investor with Highway 12 Ventures and one of the selected VCs at last week’s event in Boulder, believes the OAF is a further example of the changing landscape in the venture capital industry. As Solon notes on Highway 12’s blog, Calacanis and OAF Boulder hosts Brad Feld and David Cohen represent a “groundswell of young investors” that are dedicating their lives to improving the entrepreneurial community across the country.“These guys didn’t go through a ton of effort recruiting 30 qualified investors from near and far, getting sponsors for the evening, securing a meeting place, and going through about 100 applicants for personal gain,” writes Solon. “They did it because it was the right thing to do; to set an example for angel organizations everywhere that it’s about the entrepreneur.”In an interview with Colorado Tech TV (embedded below), Calacanis expressed his satisfaction with the reception of the OAF, as well as his thoughts on the event’s impact on the evolving venture funding ecosystem.“We’re not trying to replace other events like Open Coffee or the Tech Meetup — those are great events for networking,” said Calacanis. “[But] there is definitely a market need for a legitimate angel forum. The other forums out there were not really filled with angel investors, […] and people were paying to pitch to a room of a hundred people with maybe two or three possible investors.”For those considering applying for the San Francisco and New York events, Boulder participant Mike Stemple of Odojo says that submitting a video application is not only a good way to stand out from the crowd, but it also helps you rehearse your pitch in a short form before the event. While he considers himself and his company extremely lucky to have been able to attend the OAF event, he encourages other startups to not count themselves out before applying.“I believe for any given event ANYONE with a well thought out idea that solves a real world problem, can articulate it, has gotten beyond the idea stage and has actually built a company around the idea, could make it to present,” writes Stemple on his blog.The Open Angel Forum is now accepting applications for New York and San Francisco, so don’t hesitate to get your application in early because there is bound to be hundreds.

False color is one of the most effective exposure tools for digital cinematography out there. This quick tip explains how to understand your false color readout to achieve perfect exposure.Most digital cinematographers are well versed in common in-camera exposure tools such as zebras or histograms, but few are familiar with false color. Unlike the more common exposure tools, false color is a feature usually reserved for higher-end broadcast monitors or EVFs. As such, younger filmmakers usually have less experience with it. They don’t use it to their advantage on set the way they should.Using false color on your monitor will display an image from your camera that looks something like this:The concept of false color is quite simple: different luminance values are represented by distinct colors to give you a clear understanding of the exposure levels of every part of your image. For instance, 0 IRE (your black level) may appear pink, whereas 100 IRE (your white level) will appear as red. This means anything that shows as pink is clipped to black, and anything red is clipped to white.While it might appear daunting at first, once you understand how to read false color and what the different colors actually mean, you’ll be able to expose your image much faster and more effectively than with many other exposure tools.Color chart via Manhattan LcdThe key to exposing quickly and accurately using false color is to focus on skin tones first. Typically, skin tones should fall in the 70 IRE range, which will appear as light grey. Once you set your exposure so that your talent’s skin tone appears grey, you know the image is well exposed — at least as far as the talent is concerned. From there, you can simply scan the frame for any areas that are over or underexposed and make lighting or framing adjustments accordingly.This video from Aputure shows how to read false color on one of their monitors. It’s a great watch if you’ve never used false color before.How do you use false color on set? Share in the comments below.
