Probability computation is a complex process and even using a calculator can be difficult. But normal probability calculations can be performed quickly with the help of calculator once you know how to use it. So when you have to calculate a probability from a normal distribution you can use the functions on your scientific calculator. You can use the normal CDF function from you calculator to compute the area under a normal curve. The function requires lower band and upper band values, the me...

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...

Apple doesn't include its Calculator app on the iPad and never did. One almost appeared over 12 years ago but was nothing more than a blown-up version of the iPhone app. Since then, the company still hasn't made an iPad-optimized calculator, and there is no shortage of third-party alternatives to fill the gap. It may happen one day, but for now, these are the best calculator apps for your iPad.
While there's an art to surviving the all-nighter, there's also an art to staying awake throughout the day when you're operating on little to no sleep. In 1964, the record for sleep deprivation was set by 17-year-old Randy Gardner, who stayed awake for an incredible 264 hours and 12 minutes. Now while we're not out to challenge Randy for his title, we can certainly look to him for inspiration in beating back our own fatigue.
Most of us have conducted an investigatory science project without even knowing it, or at least without knowing that's what it was called. Most science experiments performed, from elementary to high school students and all the way up to professional scientists, are investigatory projects.
The Calculator app is probably one of Apple's most-used iPhone apps, yet I always meet people who don't know all the little tricks there are to using it more efficiently. You may know most of them, but there's a chance you don't or at least forget about some of them.

There are all kinds of theories—many supported by science—about what causes Alzheimer's disease. Tangles of protein called ß-amyloid (pronounced beta amyloid) plaques are prominently on the list of possible causes or, at least, contributors. An emerging theory of the disease suggests that those plaques aren't the problem, but are actually our brains' defenders. They show up to help fight an infection, and decades later, they become the problem.
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.
NASA is going going to Saturn's moon Titan, and the space organization is using augmented reality help them do it.
Nineteen days ago, several hundred people could have been exposed by a traveler with measles in Nova Scotia, Canada. The next day, someone flying from Minnesota to Nebraska may have spread the measles to other passengers. A couple weeks ago, it's possible that a man and his six-month old child spread the measles in several Seattle-based locations. Authorities are trying to locate persons who may have been in contact with these people. None of the persons with measles were vaccinated. Why?

Before there was Gray's Anatomy, physicians and medical students used anatomical flap books to explore the inner workings of the human body—a scientific illustrated guide that takes its name from the moveable paper flaps that can be "dissected" to reveal hidden anatomy underneath. Similar to pop-up books, these instructional tools mimic the act of human dissection, allowing doctors and students to study the intricacies of the body normally concealed by flesh.
