Researchers explain why bicycles balance themselves Ruina Lab/Provided An experimental bicycle designed to eliminate the gyroscopic effect of spinning wheels and the "trail" of the front wheel is still stable on its own, disproving conventional theory. The 1949 movie "Jour de Fete" shows a postman frantically chasing his bicycle, which rides away on its own. It could happen. Many bicycles, even without a rider, naturally resist tipping over if they are going fast enough. Scientists and engineers have been trying to explain bicycle self-stability ever since the 19th century. Still relevant after decades, the Beatles set to rock 9/9/09 (CNN) -- "Number nine. Number nine. Number nine." "The Beatles: Rock Band," to be released Wednesday, lets players strum along with classics.
MythBusters Archive (Appropriate for Grades 6-12): MythBusters Live MythBusters Jamie Hyneman and Adam Savage shared their experiences as they make experimentation come alive through this dynamic presentation about science behind the exhibit. The interactive exhibit, created by Discovery Communications and Exhibits Development Group (EDG), in partnership with the Museum of Science and Industry in Chicago, helps inspire learning beyond the walls of the classroom. Scientists, engineers, and mathematicians drive innovation that will fuel our future.
Common Misunderstandings of Evolution: Part 1 While an open and honest debate is always a good thing, most of the time, when people are pointing out “problems” in evolution, their qualms arise from a misunderstanding of what evolution actually is and how the mechanisms of evolution actually function. Below are some of the most common misconceptions (or questions) in evolution and how science answers these concerns. Q1.) How does evolution explain the origins of life?

From NOVA Next | Feb 22, 2017 Key Brain Regions Found To Be Smaller in People With ADHD In the largest study of its kind, research shows people with ADHD have smaller brain regions—including the amygdala, which is responsible for regulating emotions. Web 2.0 Science Tools By Laura Turner The following web2.0 sites would be useful for science educators at the high school and middle school level. Some would also be appropriate for higher elementary grade levels. There are many new ‘tools’ or websites that take advantage of the higher speed and bandwidth of today’s Internet. Web 1.0 tools/websites were text based and web2.0 tools/websites are designed for full-motion video, 3D animations and are generally interactive in some manner. Web 2.0 can also be described as the second round of new technology development and adoption.
The Physics Classroom Topics 1-D Kinematics The motion of objects in one-dimension are described using word, diagrams, numbers, graphs, and equations. Newton's Laws Newton's three laws of motion are explained and their application to the analysis of the motion of objects in one dimension is discussed. Google’s smart contact lens: What it does and how it works It’s a question that Google officials have clearly thought a lot about, said Joseph Lorenzo Hall, chief technologist at the Center for Democracy & Technology, who was briefed on the lens before the company’s Thursday announcement. Hall said that Google assured him that the data would not be added to the company’s banks of personal information gathered from other services. “The data will never hit Google’s servers,” he said. “That’s a forward-thinking affirmative claim that they’re making. That is important.”
