Evan R Ulrich, Darryll J Pines and J Sean Humbert, “From falling to flying: the path to powered flight of a robotic samara nano air vehicle,” Bioinspiration & Biomimetics 5 045009; doi: 10.1088/1748-3182/5/4/045009. Isn’t this great? Science can be fun – and inspiring, inspired by nature. How different the attitude of these engineers than Sam Harris (01/24/2011). The evolution talk was just a joke. “Guided evolution” is an oxymoron; this is intelligent-design science all the way through. Are the authors of the paper evolutionists? Does it matter? Turn kids onto biomimetics with their own maple-copter toy and a walk under the maple trees, and let science take off again.(Visited 18 times, 1 visits today)FacebookTwitterPinterestSave分享0 The rotating helicopter resembling a maple seed, reported on 10/21/2009, has undergone numerous rounds of guided evolution (if that is not an oxymoron). The clever inventors have been trying numerous successive variations on their design, reported PhysOrg. The article includes two video clips showing the young engineers, Evan Ulrich, Darryll Pines, and Sean Humbert from the University of Maryland, testing their product. The article mentioned that their work has been published in a recent issue of Bioinspiration & Biomimetics.1 The project was inspired by watching samaras – winged seeds of maple trees and other species. The abstract states, “Inspired by the flight modalities of the bio-inspired samaras, a robotic device has been created that mimics the autorotative capability of the samara, whilst providing the ability to hover, climb and translate.” They envision the device being useful for surveillance, mapping, communications, or just a really cool toy.
By Barbara O’Neill, Ph.D., CFP®The April 2015 MFLN Personal Finance webinar was about entrepreneurship. Like many American workers, service members and their spouses are becoming entrepreneurs (a.k.a., independent contractors or freelancers) because they want to or have to. The U.S. is increasingly becoming a “freelance nation” as employers address their labor force needs by hiring people on contracts to avoid layoff hassles, payroll taxes, and fringe benefits.By Stephen DepoloIndependent contractors work project-to-project and are hired to get a job done without regard for the means by which the result is accomplished. They use their own equipment and set their own work schedule, even if it is 3 am in their pajamas! It is estimated that 4 of 10 U.S. workers will be freelancers by 2020.Becoming a successful entrepreneur requires certain personal qualities such as a strong work ethic, creativity, good people skills, a broad skill set, and comfort taking risks. It also requires different financial planning strategies compared to employees who earn a salary. Below are ten tips for aspiring entrepreneurs:You are able to deduct self-employment expenses, such as equipment, materials, and travel, directly against business income on the Schedule C tax form. Be sure to keep good records, such as a travel log for mileage.You must pay both the employee and “employer” portions of FICA tax for Social Security and Medicare totaling 15.3% of net earnings from self-employment.You can’t use a budget that assumes a regular income when you’re an independent contractor. Instead, estimate baseline expenses and set aside money from peak earning months for times with lower income.You should build a substantial emergency fund (many experts recommend 6 to 12 months of household expenses) to tide yourself over in between freelance work projects.You must make quarterly estimated taxes to the IRS by April 15, June 15, September 15, and January 15 of the following year. Set aside at least 30% of self-employment income “off the top” for taxes.You, like most Americans, must purchase health insurance. Sources include a government-facilitated Marketplace, a private policy, group insurance through a trade group, and a spouse’s employer plan.You can save for retirement using a simplified employee pension (SEP), the easiest savings plan for entrepreneurs. Contribute up to 20% of net self-employment income by April 15 of the following year.You can also fund a Roth and/or traditional individual retirement account (IRA) for retirement savings up to the larger of $5,500 ($6,500 if age 50 and over by year-end) or 100% of net earnings from self-employment.You have many resources to assist you including professional advisors (lawyer, CPA, etc.), Small Business Development Centers, SCORE, and the websites SBA.gov and eXtension.org/entrepreneurship.You should begin any entrepreneurial activity with a business plan that includes your objectives, product or service niche, marketing plan, pricing methodology, financial projections, and business title and structure.To watch a recording of this webinar, visit the event page.This post was published on the Military Families Learning Network blog on April 28, 2015. read more
The government on Thursday said it would take up the matter of Sukhsohit Singh, who had failed to pass a medical test to join the civil services despite clearing the UPSC test. Minister for Information & Broadcasting Ambika Soni has said that she would take up the matter with the law ministry and her cabinet colleagues. “The young boy cannot be denied opportunity. My heart goes out for the parents. We all need to re-look the law,” Soni said. Sukhsohit is now in Jaipur taking his medical tests after clearing the Rajasthan Administrative Services examination in April 2011. He is contemplating filing a PIL in the Supreme Court shortly on behalf of the Federation of Indian Thalassemics. He has challenged the rejection of the board after which the government constituted a new medical board at Delhi’s Ram Manohar Lohia hospital. Sukhsohit Singh spoke to Headlines Today even as he was filling up his medical forms in Rajasthan. He said he was hoping that failing the medical at the UPSC would not be considered as a precedent. Twenty-five-year-old Sukhsohit Singh of Panchkula in Haryana was denied admission to the civil services. He was declared medically unfit, because he is a thalassemia major patient. Sukhsohit Singh is probably the first person with the rare genetic disorder to clear the civil services examination. He cleared the tough multi-level test in 2008. But his dreams now lie shattered. The medical board constituted to test Singh declared him unfit to join any branch of the civil services, attributing thalassemia major as the reason. Thalassemia major is a complex genetic disorder, which causes the body to manufacture an abnormal form of hemoglobin. Hemoglobin is the protein molecule in red blood cells that carries oxygen. Thalassemia patients need a blood transfusion every three to four weeks. But that should not prevent Sukhsohit from working. The National Thalassemia Society says Sukhsohit should be given the chance to live and work like anyone else. Former top bureaucrat T.S.R. Subramaniam says he’s fully behind Sukhsohit, but there could be some genuine reasons behind the medical board’s decision.

That’s what we had after day one.”We had to rally together and find a way to get the win.”I’ve always said some of my greatest wins are in Davis Cup and some of my toughest losses are in Davis Cup so I’m going to enjoy this one.”This is what dreams are made of.”Big-serving battler Sam Groth earlier prevailed 6-3, 7-6(4), 4-6, 7-6(6) over Mikhail Kukushkin in the first singles rubber to level the tie 2-2. read more
