first_imgWILMINGTON, MA — Below are 5 things to do in Wilmington on Thursday, July 11, 2019:#1) Wilmington Bylaw Study Committee MeetingThe Wilmington Bylaw Study Committee meets at 6pm in Town Hall’s Room 9. Read the agenda HERE.#2) Wonderland Theme Park At Wilmington LibraryThe Wilmington Memorial Library (175 Middlesex Avenue) is holding a presentation on Wonderland at 7pm. Thirty years before the Wonderland Race Track was built, the site was given its name by the Wonderland Amusement Park. Conceived by a man in the Baking Soda industry who bought the land and planned by a man who had failed to build the biggest park in Coney Island. Wonderland was filled with cutting-edge rides and attractions. Its opening day broke attendance records at Revere Beach, and the park was a major success. Author Stephen R. Wilk has been researching the park for his forthcoming book Backstage at Wonderland, and will talk about the building of the park and its first year of operation, 1906. Register HERE.#3) Pints & Pages Book Club MeetingThe Wilmington Memorial Library & Reading Public Library are holding their monthly Pints & Pages Book Club Meeting at Reading Public Library. A social book group geared towards readers in their 20’s and 30’s.  The group meets on the first Thursday of every other month.  The book discussion will be hosted by librarians from the Wilmington and Reading Public Libraries. Meeting location rotates between Wilmington and Reading. Featured Book: The Kiss Quotient by Helen Hoang. Location: Reading Public Library, Reading. We’re having a potluck picnic on the patio. Bring along a dish to share! Register HERE.#4) Time For Twos At Wilmington LibraryThe Wilmington Memorial Library (175 Middlesex Avenue) is holding Time for Twos at 10:30am. This storytime for two year olds includes books, rhymes, music and movement.

Inflatable Habitats for Polar and Space Colonists

Humanity has long since established a foothold in the Artic and Antarctic, but extensive colonization of these regions may soon become economically viable. If we can learn to build self-sufficient habitats in these extreme environments, similar technology could be used to live on the Moon or Mars. Citation: Inflatable Habitats for Polar and Space Colonists (2007, January 29) retrieved 18 August 2019 from https://phys.org/news/2007-01-inflatable-habitats-polar-space-colonists.htmlcenter_img Inflatable dome for cold, high-latitude regions on Earth. The main figure (a) shows a cross-section of the suggested biosphere, and the small figure (b) shows a top-down view. The important components are labeled: a thin, transparent double film on the sunlit side (1), a reflective cover on the shaded side (2), control louvers (3), the entrance (5), and an air pump/ventilator (6). The direction of the Sun is indicated by beams of light (4). The average temperature of the Antarctic coast in winter is about –20 °C. As if this weren’t enough, the region suffers from heavy snowfall, strong winds, and six-month nights. How can humanity possibly survive in such a hostile environment? So far we seem to have managed well; Antarctica has almost forty permanently staffed research stations (with several more scheduled to open by 2008). These installations are far from self-sufficient, however; the USA alone spent 125 million dollars in 1995 on maintenance and operations.[1] All vital resources must be imported—construction materials, food, and especially fuel for generating electricity and heat. Modern technology and construction techniques may soon permit the long-term, self-sufficient colonization of such extreme environments.Why would anyone want to live there? Exceptional scientific research aside, the Arctic is though to be rich in mineral resources (oil in particular). The Antarctic is covered by an ice sheet over a mile thick, making any mineral resources it may have difficult to access. Its biological resources, however, have great potential. Many organisms adapted to extreme cold have evolved unusual biochemical processes, which can be leveraged into valuable industrial or medical techniques.[2] Alexander Bolonkin and Richard Cathcart are firm believers in the value of this chilling territory. “Many people worldwide, especially in the Temperate Zones, muse on the possibility of humans someday inhabiting orbiting Space Settlements and Moon Bases, or a terraformed Mars” Bolonkin points out, “but few seem to contemplate an increased use of ~25% of Earth’s surface—the Polar Regions.”Indeed, the question of space exploration is intriguing. We would all like to know whether there is life on Mars, but robot probes can only perform the experiments they take along with them. Only humans are flexible enough to explore a new territory in detail and determine whether there are enough resources to sustain a long-term presence. Does modern technology really permit the design of lightweight, energy-efficient habitats suitable for other worlds? Greenhouse LivingThe Sun provides the Earth and Moon with about 1400 Watts per square meter, which is ample energy to warm a habitat even when the angle of the incident light and losses due to reflection are taken into account. On Mars, the sunshine is a little less than half as strong—which means that the equator of Mars receives about as much solar energy as the higher latitudes of Earth (Iceland, for example). The most efficient way to generate heat from sunlight is, of course, the well-known “greenhouse” effect. Given a transparent or translucent roof, any structure can hold onto the energy of sunlight long enough to transform it into heat. Glass works well for this, but glass is heavy and expensive to transport.Some good alternatives to glass are now available, however, and more options are on the way. Innovative manufacturing techniques have created many useful composite materials, including translucent, flexible membranes such as Saint-Gobain’s Sheerfill®. While these materials are certainly more expensive than glass, very little is required to construct a useful shelter.In a recent article submitted to arXiv.org [3], Bolonkin and Cathcart have designed an inflatable, translucent dome that can heat its interior to comfortable temperatures using only the weak sunlight of high latitudes. While many details remain to be worked out, the essential concept is sound. To improve the energy efficiency of the structure, they propose adding multiple insulating layers, aluminum-coated shutters, and a fine electrical network to sense damage to the structure. The dome would be supported entirely by the pressure of the air inside, which can be adjusted to compensate for the added buoyancy caused by high winds. The principle advantages of this design are the low weight and flexibility of the material. If only a few people at a time need shelter, an enclosure the size of a small house would weigh only about 65 kg, or as much as a person. This is light enough even for a space mission, and setting up would be as easy as turning on an air pump. For large colonies, enough membrane to enclose 200 hectares would weigh only 145 tons. The interior would be warm and sheltered, a safe environment for the construction of more traditional buildings and gardens.Bolonkin and Cathcart have attracted attention with their proposal, but a prototype has not yet been constructed.Notes:[1] Source: 1996 report on the U.S. Antarctic Program by the National Science and Technology Council; www.nsf.gov/pubs/1996/nstc96rp/chiv.htm[2] Source: Sam Johnston, “Recent Trends in Biological Prospecting”, UN University Institute for Advanced Studies; www.ias.unu.edu/sub_page.aspx?catID=35&ddlID=20[3] xxx.arxiv.org/abs/physics/0701098By Ben Mathiesen, Copyright 2007 PhysOrg.com.

KMC chalks out plan to develop Hatgachia model bustee as an ideal

first_imgKolkata: The Kolkata Municipal Corporation (KMC) has made up a comprehensive plan to develop its model bustee at Hatgachia in Dhapa area as an ‘ideal’ one. The civic body will give a fresh coat of paint to the houses in the slum situated adjacent to the road and will then adorn it with paintings of freedom fighters and other great men who has made the state proud. The paintings will also have short messages of the famous personalities.”Our aim is to curb the tendency of littering the walls of the houses in the slum. When there will be such paintings, people will hesitate to spit or make the walls dirty. This will prevent visual pollution which is a common sight, particularly in the slums,” a senior official of the Bustee Development department of KMC said. Also Read – Rain batters Kolkata, cripples normal life”The slum dwellers, particularly the young ones, lack moral values. And for developing a model slum, it is important to instill such values within them. We are hopeful that this act will be a step in that direction,” said Swapan Samaddar, Member, Mayor-in-Council (Bustee Development). It may be mentioned that Hatgachia bustee has already been developed as a model slum and finishing touches are now being given. The slum has a children’s park, community hall, primary school, health centre and playground. The department has also taken up initiatives for social awareness to uplift the lifestyle of slum dwellers. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killed”We are holding camps in the bustees where officials from our department will interact with the slum dwellers. The programme will be taken up in all the 16 boroughs of KMC, with the aim to educate them about cleanliness, hygiene and similar other practices,” the official added. Celebrities from the field of sports, entertainment and literature are being roped in for conducting such programmes successfully. It may be mentioned that KMC has planned to develop nine slums in the city into ‘model slums’, to ensure that people in these areas get the basic civic amenities. “The basic aim is improvement in the socio-economic condition of these slums. The concept of model bustee is to ensure basic civic amenities like drinking water, drainage system, toilets and lighting facilities at every house. However, we will create additional infrastructure wherever there is availability of space,” Samaddar said.last_img read more

Meet Dash and Dot Robot Toys That Teach Kids How to Code

first_img Register Now » Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goals Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right. December 23, 2014center_img 3 min read What’s harder: shopping for the holidays or teaching your kids the basics of computer programming? A startup called Wonder Workshop is aiming to make both a little easier.Based in San Mateo, Calif., Wonder Workshop builds robots that help teach children age 5 and up how to code. Initially named Play-i, the company was founded in 2012 by CEO Vikas Gupta, CTO Saurabh Gupta and Mikal Greaves, VP of product.The inquisitive robots the company has built — Dash and Dot – are blue and orange, one-eyed, round and chatty. They can sense objects around them (to prevent bumping into walls) and respond to light and sound.Wonder WorkshopRelated: This Is What Robots Will Be Doing in 2025The robots were designed to be “emotionally engaging,” and inspire kids’ creativity.  “The way that the head and eye move independent of the body, that drives engagement,” says Gupta. “We also wanted it to be something kids could imagine as anything — we didn’t want it to be something they were already familiar with like a four-legged animal or two-legged human — so it has three legs…and one eye.”Wonder Workshop has developed four different apps to use with Dash and Dot that aim to teach programming and coding lessons through music, mazes, paths and puzzles. Users on the older side can even try their hand at making their own iOS and Android applications for the robots through Wonder Workshop’s open API. Related: This Robotic Butler Could Make Your Next Hotel Stay…InterestingWonder WorkshopThe duo – which, together, carry a $259 price tag — connect to Apple and Android devices via Bluetooth and can be charged by a computer.Wonder Workshop raised $1 million in seed funding prior to launching a crowdfunding campaign in October 2013. The campaign quickly gained an enthusiastic following, generating $250,000 in four days, and ultimately netting $1.4 million. Wonder Workshop has gone on to raise an additional $8 million in Series A funding, according to Crunchbase.Gupta says he was inspired to create the robots from watching his young daughter at play, and ultimately, he says he could see them utilized not just at home, but in the classroom as well.Related: People Prefer Robot Bosses, Study Shows“We are working with schools to make it available and accessible for a classroom, and building specific applications that would work well in that setting,” he says.And there seems to be a need. Last year, only 44 percent of high-school graduates were prepared for college-level math and 36 percent were prepared for university-level science courses, according to the National Math and Science Initiative. To that end, Wonder Workshop promises to appeal to curious kids and parents who want to inspire an enthusiasm for coding and programming in their kids early.  Related: Meet Plantoid, the Robot That Grows Like the Roots of a Plant last_img read more
