With funding from the National Science Foundation, Maysan Ghovanloo at Georgia Tech designs technology that allows disabled people to control everything - from wheelchairs to computers - with their tongue. Jason DiSanto, who is paralyzed from the neck down, is testing the tongue controller by navigating his wheelchair around a small course.
Meet Boss – the car that can drive itself. Boss is the invention of Carnegie Mellon researcher Raj Rajkumar and his team. It has 18 sensors, including a three dimensional laser and onboard computers that connect to GPS and mapping software. When it comes to knowing the rules of the road, Boss rarely makes a mistake. With support from the National Science Foundation, it was built for a Department of Defense competition called the DARPA Urban Challenge. Boss negotiated the roads, including traffic, and was the hands down winner in 2007.
This program is devoted to the senses that bring information of more distant events. The camera shows a reckless driver careening down a road—and then takes the viewer inside his eye, where the image of the potential crash site is pictured. The camera enters the ear, showing how the linked bones vibrate in response to a sound, and by using a computer graphic sequence, shows how the eye focuses on an image.
Fire is an ever-present danger in the world of NASCAR. Drivers are protected by fire-resistant Nomex fabric. These firesuits help keep the drivers safe by decreasing the rate of heat transfer. Part of "The Science of Speed" series.
This episode explores the necessary and yet often times annoying relationship between humans and insects. Some of the insects highlighted include honey bees, driver ants, silk worms, locusts, Anopheles mosquitos, aphids, money spiders, and army ants. Part of the "Nature's Micorworlds: Insect Specials" series.
This decade is best remembered for disco and Watergate. But the inventions in the 1970s mark the beginning of the digital age to come. Featured inventions include: cell phones, the bomb disposal robot, Post It Note, hybrid cars, and digital cameras.
Part of the "Green Careers" series. Introduces job opportunities in recycling, including collection, transportation, receiving and sorting, disassembly, handling hazardous materials, scheduling, operations, and plant management. Recycling provides opportunities for young people to start with a temporary or part-time job, then move up to supervisory and management responsibilities. Jobs profiled include the following: e-waste entrepreneur, plant manager, biofuel coordinator, and truck driver.
Increasing the time of a collision from a tenth of a second to two tenths of a second can make a huge difference in the number of "G's" a driver experiences. The car, the track, the seat belts, and seat construction spread out the force of impact and save lives. Part of "The Science of Speed" series.
In 2008, NASCAR driver Michael McDowell lost control of his car and hit the wall at 170 mph. Fortunately, McDowell was able to walk away from the accident, which is a testament to the safety elements NASCAR has instituted. NASCAR officials apply the scientific principle of the conservation of energy to strengthen their safety measures. Part of "The Science of Speed" series.
NASCAR tires are filled with nitrogen to help protect against heat caused by friction. Friction also increases the air pressure in tires, and NASCAR drivers don't want a tire to blowout during a race. The use of nitrogen helps the crew predict how hot the tires will get. Part of "The Science of Speed" series.
Part of the "Active Physics, Third Edition" series. Contains the following sections: "Using Models: Intersections with a Yellow Light," "Sports Montage Introduction," "Conservation of Energy: Defy Gravity," "Safety Montage Introduction," "Acceleration Due to Gravity: Free Fall on the Moon," and "Modeling Human Motion: Bounding on the Moon."
Engine power is constrained at superspeedways like Daytona and Talladega, which reduces the speed of the cars. Teams use aerodynamics to gain an advantage due to the constraints. They adjust the cars to minimize drag, and driver's use the technique of drafting. Part of "The Science of Speed" series.
Using only gasoline to power cars back in 1905 was cheaper and easier, so the hybrid car was forgotten-until recently. The modern hybrid car has two distinct power sources working together to make it run: gas and electric power. Since the fuel widely used now is a non-renewable resource and becoming increasingly less affordable, the hybrid car is making a comeback. The benefit of the hybrid is that instead of running on gas, it uses non-polluting electric power when possible. Also, it helps cut pollution and saves drivers money at the gas pump.
