17-year-old NRI girl earns admission to all 8 Ivy League schools

                       Getting into one Ivy League school considered is a big deal but an Indian-origin student from Virginia earned admission to all eight ivies, which are considered the most prestigious universities worldwide.

Pooja Chandrashekar got a 4.57 grade-point average, scored a 2390 (out of 2400) on the SAT, and aced all 13 of her Advanced Placement exams, the Washington Post reported.

Virginia-born Pooja Chandrashekar said that she decided to apply to all eight ivies hoping to get into just one of them, because college admissions were really unpredictable. And now she is in a has to choose from Harvard, Yale, Princeton, Cornell, Dartmouth, Columbia, Brown, and the University of Pennsylvania besides six other including Stanford and MIT.

She has narrowed her list to Harvard, Stanford and Brown as there she can get into a  programme that ensures her admission to the university's medical school. 

Pooja Chandrashekar also founded a national non-profit organisation that encourages middle-school girls to participate in science, technology, engineering and math (STEM) programs.

She also developed a mobile app that analyses speech patterns and predicts with 96 per cent accuracy if a person has Parkinson's disease.


In an email interview she told Hindustan Times: 'I feel so honored and humbled to be accepted to these colleges and be recognised for my work and efforts over the past four years.'

Pooja Chandrashekar's guidance counsellor, Kerry Hamblin was quoted by The Columbus Dispatch saying: 'She’s taking the hardest courses, the most challenging that we offer, and has exceeded anyone’s expectations in all of them.'

The 17-year-old senior at Thomas Jefferson High School for Science and Technology in her website says she loves coding, creative writing, organising and participating in hackathons, traveling and tasting good food.

A bicycle that runs at 80 kmph



Audi unveiled an extremely emotion-inspiring sports machine, the Audi e-bike Wörthersee at Wörthersee in Carinthia, Austria. The prototype cycle combines an electric drive and muscle power. Head of Design Wolfgang Egger comments: “As a high-performance e-bike for sports and trick cycling, it features the Audi core competences of design, ultra, e-tron and connect.” The Audi e-bike Wörthersee puts in its first major appearance at this year’s Wörthersee Tour, the 31st meet for Audi, VW, Seat and Skoda fans; trial biker Julien Dupont and downhill specialist Petra Bernhard will demonstrate their stunts and streetbike skills.













1. The uncompromising dynamism of the bike prototype is fully visible at first sight. “When developing the Audi e-bike Wörthersee we drew on motor racing design principles for inspiration,” explains Hendrik Schaefers, one of the designers at Concept Design Studio Munich. “The e-bike appears incredibly precise, highly emotional and strictly functional. Indeed, the design effort focused on its function as a sports machine. All design elements are thus firmly aligned to the technical features.”




























The airy frame boasts a low center of gravity and a compact overall volume. In this way, the e- bike is superbly agile at the sporty handling limits. The lithium-ion battery is incorporated into the frame and needs 2.5 hours to freuteully charge. On long trial tours, only a few simple steps are required to remove the battery and replace it with a charged one





The frame and the swinging arm that holds the back wheel are made of carbon fiber- reinforced polymer (CFRP). The same material is used for the 26” wheels, which feature an innovative “Audi ultra blade” design with broad flat spokes for an optimized transmission of pedal power. “We were able to demonstrate with the choice of materials just how closely design goes hand in hand with expertise in ultra lightweight construction,” Hendrik Schaefers comments.




















Homogeneous LED light strips round out the frame and create the immediately recognizable Audi light signature. For extreme tricks and stunts the seat can be lowered to run flush with the frame itself. At the press of a button, the seat then rises up and the biker can adopt a comfortable position.









1. The cyclist can choose between a total of five cycling modes – pure muscle power, the electric motor alone, or pedaling supported by the electric motor. In the “Pure” mode, the drive power is purely the product of the cyclist’s legs, while in “Pedelec” mode you are supported by the electric motor that then makes speeds of up to 80 km/h (50 mph) possible and gives you a range of 50-70 kilometers (31-44 miles).




















If you select “eGrip”, the Audi e-bike Wörthersee runs solely on the electric motor and can reach a top speed of 50 km/h (31 mph). The cyclist then controls forward momentum using a gripshift and can configure the power as desired using the computer






When performing wheelies, an electronic control system supports the rider when performing tricks and back-wheel biking. Different modes can be set using a smartphone or directly on the e-bike – either “Power Wheelie” mode, with adjustable wheelie angle for less skilled bikers or “Balanced Wheelie” mode for sporting challenges.





1. In "Balanced Wheelie" mode, the electronic control system maintains the rider’s balance, by compensating the biker’s movements forwards or backwards via the electric motor.
















This means the rider can influence the bike’s speed by shifting weight: if you lean forwards the bike picks up speed, and if you lean back it slows. You select “Training” mode if you want to keep your performance constant for training purposes.











The electric motor is located at the lowest point on the frame and drives the bottom bracket shaft directly. The maximum torque delivered to the rear wheel is 250 Nm (184.39 lb-ft)..

Cycling modes and countless other functions can be set using the touchscreen on-bike computer. The cyclist's smartphone hooks up by WLAN to the computer – when you start cycling, for example, the immobilizer is deactivated. Video images of the trial drive or of a trick, as recorded via the in-helmet camera, are uploaded to the Internet in real time via your smartphone.
