If you have a fossil, you can tell how old it is by the carbon 14 dating method. This is a formula which helps you to date a fossil by its carbon. If a fossil contains 60% of its original carbon, how old is the fossil? The half life of carbon 14 is 5600 years. That means this is how long it takes for half the nuclei to decay. After 5600 years, if we start with a gram, we end up with half a gram. This rather complex formula shows you how to solve this puzzle using accepted scientific methods.
In this video from Socoolscienceshow, Crazy Chris explains to us how magicians make things disappear. For this he uses a plate, cup, and a napkin. You cover the cup and plate with a napkin. He removes the napkin with the cup and shows that he taped the cup to the bottom of the plate so they are both removed at the same time. To maintain the look of the cup in that napkin when it's removed he shows that he trace the cup onto some construction paper cut it out, and tape it to the napkin. Then h...
In this video tutorial the author shows how to use the Cosine Law. He shows how to find an angle of a triangle where he know all the sides of a triangle, using the cosine Law. He uses a lower case letter to designate a side and a capital letter to designate an angel apposite to that side. He gives the formula for the cosine law using a triangle as an example. Now he goes on and demonstrates how to use a scientific calculate. He shows how to use the degree mode in the calculator to solve these...

Editor's Note: The claims by Vani Hari which were originally detailed in the article below about azodicarbonamide were unscientific in nature. This article has been updated to reflect that and provide more scientific context on the issue.
NASA is going going to Saturn's moon Titan, and the space organization is using augmented reality help them do it.
Using a technology we like to call "Hive Computing," several Android apps allow you to contribute idle processing power to help further scientific research. This basically means that when you're not using your phone or tablet, it can join forces with other idle devices to form a supercomputer that scientists can use to potentially make a world-changing breakthrough.
We've already taught you how to clench your fist to make healthier food choices, and how to make sure you eat healthily at a restaurant, but it turns out there are even more mind hacks we can use in our never-ending quest to control our appetites.
Detailing your car keeps it in top shape and looking like new. By washing and detailing regularly your vehicle will impress passerbys every day. In this two part series, The Smoking Tire shows you how to properly detail your car at home without accidentally ruining your paint in the process. This can be easily done from home, and doesn't take much advanced skill. Check out this step by step and keep your car shiny, no matter how old it is!
Homopolar motors tend to be typecast as simplistic in nature, and that's true for the most part. The bare minimum requirements are a battery, conductor, and magnetic field, but when it comes to Valentine's Day, they're nothing short of complex.
