Roller Coaster Game Welcome to the death defying Funderstanding Roller Coaster! This simulator is designed for people who want to design their own thrilling coaster and educators who want to use a cool activity to simulate the application of physics by using an exciting interactive tool and access to a wonderful reference source. It is your mission to become a roller coaster designer so that you can achieve maximum thrills and chills without crashing or flying off the track (unless that’s how you like your coaster to work!). If you accept this mission you must decide on a number of factors.
The Lego DACTA computer interface 70909 (Findings by Anders Isaksson) I recently (May 2002) bought the Lego DACTA sets 9701 and 9702, with accompanying computer interface. Those sets are the precursor to the modern CyberMaster and Mindstorms sets, but still quite capable. The software with the package, TechnoLogica, is nice, but of course very limited, so I just had to roll my own (I'm using Borland Delphi 5.0). This is a work in progress, still in it's very infancy, but I'll publish it anyway.
Rosalind Franklin: DNA's unsung hero - Cláudio L. Guerra Rosalind Franklin had a life full of challenges, not just scientifically but socially. She had to fight prejudice in an environment dominated by men in a time when women were presumed to be housewives and nothing more. Her success was recognized by many of her peers, but in the race for the structure of DNA and the recognition of key innovators in this field, sexism played a major role. Years after her death, Brenda Maddox and Anne Sayre worked on biographies about Franklin and could clarify some aspects of her history that might otherwise have gone overlooked. Maddox’s work gave rise to an interesting documentary by PBS’ NOVA called Secret of Photograph 51. Interested in learning more about early work on DNA?

Galileo Drops the Ball - Virtual Experiment In around 1590 Galileo Galilei (1564-1642) climbed up the Leaning Tower of Pisa and dropped some balls to the ground. Two balls of different masses, but of similar shape and density that were released together hit the ground at the same time. Until then it was commonly believed that heavy things fall faster than light things. Many people still believe this, and casual observation of everyday phenomena often does tend to confirm this view. If you drop a brick and a feather at the same time the brick will probably hit the ground first. But this is because of differences in the amount of friction between these objects and the air around them, not because their masses are different.
How much money teachers earn around the world How much do educators get paid for their work? We asked 17 public school teachers in communities around the world — from Kildare to Kathmandu, Johannesburg to Oslo — to tell us what they earned in one month (and how they spent it). Here’s what they said: Queensland, Australia Tell us about yourself: I’m 25; I’m a year 1 classroom teacher; this is my second year of teaching full time.
10 Search Engines to Explore the Invisible Web No, it’s not Spiderman’s latest web slinging tool but something that’s more real world. Like the World Wide Web. The Invisible Web refers to the part of the WWW that’s not indexed by the search engines. Most of us think that that search powerhouses like Google and Bing are like the Great Oracle”¦they see everything. Unfortunately, they can’t because they aren’t divine at all; they are just web spiders who index pages by following one hyperlink after the other. But there are some places where a spider cannot enter.

Gay, Lesbian Teens More Likely to Suffer Rapes, Attacks: CDC FRIDAY, Aug. 12, 2016 (HealthDay News) -- Lesbian, gay, and bisexual high school students are much more likely to be victims of physical and sexual violence and bullying, and more needs to be done to protect them, a new U.S. government study says. "These tragic disparities call for accelerated action by public health and education agencies, communities, and families to protect the lives of lesbian, gay and bisexual youth," said Dr. Jonathan Mermin. He is director of the National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention at the U.S. Centers for Disease Control and Prevention. Getting a better assessment of the extent of the problem, "is critical to protect the health and well-being of more than one million lesbian, gay and bisexual high school students," he added in an agency news release.
100 Useful Tips and Tools to Research the Deep Web By Alisa Miller Experts say that typical search engines like Yahoo! and Google only pick up about 1% of the information available on the Internet. The rest of that information is considered to be hidden in the deep web, also referred to as the invisible web. So how can you find all the rest of this information? This list offers 100 tips and tools to help you get the most out of your Internet searches. Motion: Forces Forces are a big part of physics. Physicists devote a lot of time to the study of forces that are found everywhere in the universe. The forces could be big, such as the pull of a star on a planet. The forces could also be very small, such as the pull of a nucleus on an electron.
