Sharing a love for science

first_imgIn the Harvard Science Center, hundreds of Cambridge eighth-graders gasped in amazement as they watched liquid nitrogen violently and instantaneously transform from a boiling liquid to a frozen solid and back again — all while trapped under the pressure of a bell jar’s clear dome.“You’re now among the very few people in this world who have seen nitrogen not just as a gas and a liquid — which is pretty cool all by itself — but also as a solid,” said the science lecture demonstrator, Daniel Rosenberg, as the students burst into wild applause.Rosenberg’s demonstration was part of the third annual Science and Engineering Showcase, which brought nearly 400 eighth-graders from Cambridge public schools to Harvard’s campus. The students viewed demonstrations by Harvard graduate students and faculty, toured facilities such as the Center for Nanoscale Systems, and presented hundreds of their own science projects under the tent on the Science Center Plaza.Prior to the showcase, students from the Harvard School of Engineering and Applied Sciences (SEAS) had made regular visits to the young scientists to support their projects and provide feedback, all part of the University’s broad support of local schools.The eighth-graders projects were as diverse as the students themselves, exploring the potential future of solar-powered vehicles and boats, envisioning clay huts strong enough to resist earthquakes, imagining the next level in clean-up solutions for oil spills, and delving into the endless possibilities of Lego robotics.Later, in the Maxwell Dworkin building, amid dozens of demonstration booths staffed by SEAS graduate students, two girls from Vassal Lane Upper School held a passionate and timeless debate: whether the “gummy worm” in Janessa Alston’s hand — the result of a experiment at a booth examining the composition of water — was fascinating or gross.“It’s slimy,” Narika Guichette shrieked, recoiling, while her friend remained philosophical.“It’s kind of cool,” Alston said, peering closer at the clear, sticky strand in her fingers. “I just like to learn about different things.”Throughout the day, local leaders and Harvard faculty, graduate students, and administrators were on hand to encourage the eighth-graders to continue their adventurous explorations in science.Janessa Alston (left) and Narika Guichette, both Vassal Lane Upper School students, experiment with a “gummy worm.”“The creativity, spirit, confidence, and hard work that you’ve shown in your projects — that’s what makes a difference in science and in life,” said Jeffrey Young, superintendent of schools for the city of Cambridge.  “It’s the kind of thing, frankly, that gets you to a place like Harvard.”Christine Heenan, vice president of Harvard public affairs and communications, congratulated the students on their innovative projects. “I saw many experiments today that I thought could be the forerunners to help make the world a better place, and that is really exciting,” she said.Heenan reminded the students that Harvard isn’t just part of their neighborhood; for some, it may also be part of their future.“This year, we’re enrolling 11 students from Cambridge Rindge and Latin,” she said. “So as you think forward to high school, think about college and the role that science can play in your acceptance into college. We hope to welcome many of you to the class of 2021.”Cambridge Mayor Henrietta Davis thanked President Drew Faust and other Harvard leaders for being “such great partners,” and asked the students to embrace being the scientific leaders of tomorrow.“Things need to be discovered and changed, and you’re the ones that are going to lead the way,” Davis said. “Keep being curious. Keep working hard. Even if you don’t become a scientist yourself, be scientifically literate, because it’s going to be very important in the years to come.”Kathryn Hollar, director of educational programs at SEAS, said the event is one of many ways that Harvard supports science learning in local schools.“It’s exciting for us to have every Cambridge eighth-grade student here to share their great ideas in science and engineering with scientists at Harvard,” she said. “School-aged children have a natural desire to invent, and our job is to nurture that interest and keep children curious and inventing.“The great thing about today is that someone in this room today is going to design something that will change the world,” said Young. “I can’t wait to find out who that will be.”last_img read more

U.S. Unemployment Claims Rise

first_imgShare:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to email this to a friend (Opens in new window) MGN ImageWASHINGTON (AP) – The number of Americans applying for unemployment benefits rose last week for a second straight week to 778,000, evidence that the U.S. economy and job market remain under strain as Coronavirus cases surge and colder weather heighten the risks.The Labor Department’s report Wednesday said that jobless claims climbed from 748,000 the week before. Before the virus struck hard in mid-March, weekly claims typically amounted to only about 225,000. They shot up to 6.9 million during March before dropping, yet they remain historically high more than eight months later, with many businesses unable to fully reopen.The spike in virus cases is intensifying pressure on companies and individuals, with fear growing that the economy could suffer a “double-dip” recession as states and cities reimpose restrictions on businesses.“With infections continuing to rise at an elevated pace and curbs on business operations widening, layoffs are likely to pick up over coming weeks,″ said Rubeela Farooqi, chief U.S. economist at High Frequency Economics. “Even as job growth is continuing, the labor market remains under stress and far from complete recovery.″ The total number of people who are continuing to receive traditional state unemployment benefits dropped to 6.1 million from 6.4 million the previous week. That figure has been declining for months. It shows that more Americans are finding jobs and no longer receiving unemployment aid. But it also indicates that many jobless people have used up their state unemployment aid — which typically expires after six months.More Americans are collecting benefits under programs that were set up to cushion the economic pain from the pandemic. For the week of Nov. 7, the number of people collecting benefits under the Pandemic Unemployment Assistance program — which offers coverage to gig workers and others who don’t qualify for traditional aid — rose by 466,000 to 9.1 million.And the number of people receiving aid under the Pandemic Emergency Unemployment Compensation program — which offers 13 weeks of federal benefits to those who have exhausted state jobless aid — rose by 132,000 to 4.5 million.All told, nearly 20.5 million people are receiving some type of unemployment aid. (Figures for the two pandemic-related programs aren’t adjusted for seasonal variations.)The intensifying pandemic is threatening to accelerate the pace of layoffs as more states and localities limit public gatherings and mandate fewer hours and smaller capacities for restaurants, bars and other businesses. Regardless what governments do, many Americans are likely to stay home — and away from local businesses — until they feel safe again.The Conference Board, a business research group, reported Tuesday that consumer confidence weakened in November, pulled down by lowered expectations for the next six months.The data firm Womply says that 21% of small businesses were shuttered at the start of this month, reflecting a steady increase from June’s 16% rate. Consumer spending at local businesses is down 27% this month from a year ago, marking a deterioration from a 20% year-over-year drop in October, Womply found.The heart of the problem is an untamed virus: The number of confirmed infections in the United States has shot up to more than 170,000 a day, from fewer than 35,000 in early September. The arrival of cold weather in much of the country could further worsen the health crisis.Meanwhile, another economic threat looms: The impending expiration of the two supplemental federal unemployment programs the day after Christmas could end benefits completely for 9.1 million jobless people. Congress has failed for months to agree on any new stimulus aid for jobless individuals and struggling businesses after the expiration of a multi-trillion dollar rescue package it enacted in March.Most economists warn that without more government aid, hardships will deepen for individuals, small companies and localities and states, which will likely have to slash services and jobs.The expiration of benefits will make it harder for the unemployed to make rent payments, afford food or keep up with utility bills. Most economists agree that because unemployed people tend to quickly spend their benefits, such aid is effective in boosting the economy.When the viral outbreak struck in early spring, it flattened the economy with stunning speed. Employers slashed 22 million jobs in March and April, sending the unemployment rate rocketing to 14.7%, the highest rate since the Great Depression.Since then, the economy has regained more than 12 million jobs. Yet the nation still has about 10 million fewer jobs than it did before the pandemic erupted.last_img read more

Lessons of the Week: Idina Menzel, Matthew Morrison & More!

first_img Star Files It’s Friday, so throw on your Wicked leggings and start your weekend with the Lessons of the Week! Broadway took us on yet another wild ride over the past seven days with myriad belters, geniuses and Broadway.com boyfriends making headlines. We’re here to recap it all for you, so let’s not waste any more time (are your Wicked leggings on?) and get started.       If You Belt, Idina Will ListenIdina Menzel is taking If/Then on the road. That’s right: the cardigan and blazer are coming to a city near you! It’s truly a cause for a celebration, and the most sensible way to do so is to belt your face off. If you record a video doing just that and send it to us, we might a) have Idina Menzel say your name b) fly you out to California to see the show! Now please excuse us while we do some serious warmups.Don’t Send the Platts Schmackary’sJonah Platt makes his Broadway debut as the ever-so swankified Fiyero in Wicked, and his brother, stage and screen fave Ben, had but one piece of advice for him: “Stay away from dairy and gluten.” OK, there are a few vegan/gluten-free cookies at Schmackary’s. But wait sec, Ben? That’s all your advice?! You didn’t have any tips about kite-flying?Joshua Castille’s Got Smash-ing JunkAt the opening night of Spring Awakening, we asked the cast and guests what their junk was (because we’ve all got our junk). Lots of love for fiancés, Real Housewives, chocolate and yes, even us (the feeling is mutual, Mientus!). However, Joshua Castille, who plays Ernst in the Deaf West production, won our hearts by enthusiastically signing “Debra Messing.” Same, Joshua. Same.Matt Morrison Has a Thing for FLOTUSWe all have our “Celebrity Free Pass” lists. For example: “I’m totally into you and promise to stay committed, but if Debra Messing comes along, all bets are off.” We suspect Finding Neverland’s Matthew Morrison appears on many people’s lists, but who is on his? None other than First Lady Michelle Obama. Just remember, kids: Matty Fresh may be cute, but no boy is cute enough to keep you from getting an education.Tevye’s Been Ready for 30+ YearsWhen we took a trip out to Pikes County to catch some R&R with upcoming Fiddler on the Roof star Danny Burstein, the five-time Tony nominee revealed that Tevye’s been in the cards for years. Some 30-35 years, to be exact; he’s had a copy of the book on his shelf for that long. It’s unclear whether he stole it from a high school library, but the checkout card is still intact.Carly Rae Is a Beautiful Blonde PineappleShe’s going from pop princess to beauty school dropout! Broadway alum Carly Rae Jepsen will trade Cinderella’s ball gown for a Pink Ladies jacket when she takes on the role of Frenchy in Fox’s live telecast of Grease. Sure, she may be at an all-time high with E•MO•TION, but even that’s not stopping her from living out her musical theater dreams she’s had since the age of seven.Lin-Manuel Miranda Is a Certified GeniusLin-Manuel Miranda has racked up 62,500 Hamiltons from the MacArthur Foundation. The Tony winner and Hamilton star/composer is one of the latest individuals awarded a “Genius Grant.” Also honored were puppeteer Basil Twist, set designer Mimi Lien and Beth Stevens (the neuroscientist, not the Broadway.com Managing Editor. Although that Beth Stevens deserves a f**king Genius Grant, too.)Bryce Pinkham Has a ‘Genius’ PlaylistThe Hamilton cast album has been out for one week, and it has already taken over the lives of theater people everywhere. Not even the devilishly charming Monty Navarro is safe. On his final Full Monty episode, Gentleman’s Guide headliner Bryce Pinkham was all about the #Hamiltunes on his commute to the Broadway Flea Market. See? Broadway stars (and First Ladies): they’re just like us!Tim Minchin Wants to Get Dirty with LesliWhen Matilda composer Tim Minchin was asked who would win in a hypothetical cage match between him, Matilda and Lesli Margherita, he had a proposition: ditch the fictional bookworm and have him mud wrestle with the Dames at Sea queen. We’re not exactly sure what that solves, if anything, but maybe let us know if and when this happens. Can we bring a camera crew? Or can you vlog it?We Think of Elsie (Fest) to this Very DayStep aside, Coachella. Do you have Laura Osnes and Aaron Tveit singing “Falling Slowly” or Darren Criss channeling his inner Sally Bowles? We think not. That’s exactly what the Hedwig and Glee alum brought to his show tune-filled outdoor music festival, along with several other gems. The Times Square annual concert Broadway on Broadway is sadly a thing of the past, but Elsie Fest should live on for years to come! View Commentscenter_img Idina Menzellast_img read more

ERRI leads the quest to cut railway noise

first_imgINTRO: While railways can rightly claim many ’green’ credentials, noise reduction is one field where they need to make rapid progress. The European Rail Research Institute is tackling the issue urgently BYLINE: Brian Hemsworth BSc, CEng, FIOA and William Bird MA, CEng, MIMechE, MCIT*BYLINE: * Brian Hemsworth is Manager, Noise & Vibration, at the European Rail Research Institute, and William Bird is Project Co-ordinatorRAILWAYS are widely accepted as most environmentally friendly transport mode, but their ’greener’ reputation is being increasingly scrutinised by policy makers and environmentalists, particularly with respect to noise. There is a perception that air and road transport have made great steps forward in reducing noise levels, but rail’s reputation in this area needs to be enhanced.The EU Green Paper on Future Noise Policy has targeted railway noise as a prime area for legislation, and specialist railway engineers have long been aware of the implications. To avoid the possibility of punitive legislation that could seriously affect traffic levels, especially at night, it is important that concerted action continues to be taken at international level. The European Rail Research Institute is addressing noise issues head-on, in three main areas.The backgroundERRI was commissioned by the International Union of Railways to research noise and vibration through Specialist Committees of senior acoustic specialists drawn from European railways. The studies are complementary to those by individual railways, but a collaborative approach ensures that expert advice is exchanged in areas of common interest and avoids duplication of effort. Work has included noise from diesel locos, rolling noise, measurement standards and human responses to railway noise.More recently, funding has become available through European Union initiatives. Consortia have been established with universities, research organisations and industry to bid for EU funding of up to 50% of project costs, with the UIC providing balancing finance. Member railways carry out aspeccts of the work, and in specific projects, have also committed funds. In all cases, ERRI manages UIC funding, and provides project management and technical support – either directly or via sub-contractors.In parallel, ERRI is co-ordinator of UIC-supported innovative research in critical areas fundamental to the future development of quiet railway systems.ERRI has established a unit to deal specifically with noise and vibration issues. Identifying political and environmental undercurrents, a programme has been developed for three key areas: rolling noise; innovative research; andmeasurement standards.Rolling noiseAn important contribution to the work has been the Twins software to simulate the generation of rolling noise (Fig 1). This was developed with help from Berlin Technical University, Keele University, the Netherlands Organisation for Applied Scientific Research (TNO), and noise consultants Bolt Beranek & Newmann and Vibratec.Twins was derived from the Springboard software developed by BR Research and an earlier model by Paul Remington in which rolling noise generation is considered to be a forced vibration process with vibrating wheels and rails as the radiating elements. The force is generated in the contact zone and is a linear function of the combined roughness of the wheel and rail surfaces. The consequence of this mechanism is well-known – disc-braked vehicles are significantly quieter than vehicles with cast iron tread-braked wheels because wheel running surfaces are smoother. Noise can also increase dramatically when rails become corrugated due to a significant increase in rail roughness at the wavelengths important in rolling noise generation.Twins software is internationally acknowledged and has been validated for a wide range of railway operations. Validation experiments have demonstrated that at low frequencies, sleepers are a significant noise source. Twins simulations have provided the basis for several studies into low noise systems.Acoustic specifications definedThe Optimised Freight WHeel And Track (Ofwhat) programme started in 1993 with the aim of defining optimised acoustic specifications for freight wheel and track components by combining Twins simulations with prototype testing. This was conceived as a first step in establishing a catalogue of noise reduction techniques for freight vehicles.Component specifications were derived by Twins, competitive tendering was used to manufacture components, and running tests were carried out at Velim in 1995. These assessed the effect on rolling noise of rail pad stiffness and damping, rail absorbers, optimised wheel shape and wheel absorbers. A shape-optimised wheel fitted with dynamic absorbers was developed and tested (right).The results confirmed the importance of rail pad stiffness in determining the level of generated noise. For minimum noise, a pad stiffness should be chosen where rail vertical noise and sleeper noise are equal. A reduction in track noise of 4 to 5dB(A) was achieved compared to a tested non-optimum pad with a commonly used value for its stiffness. Other treatments performed as predicted.The study demonstrated that Twins could be used for theoretical assessments to derive specifications for low noise components. It also proved that a project could be completed on schedule and within budget, with the co-operation of several European railways and suppliers. Silent Freight and Silent TrackThree projects are being sponsored by the EU Research Directorate as part of its Brite-Euram programme. Silent Freight aims to reduce freight vehicle noise by examining parameters and developing innovative solutions for existing and future vehicles. Work began in February 1996 and is due for completion in December 1999. The key elements of the project are to:last_img read more
