Thursday marks Pi Day, otherwise known as 3.14, which marks the ratio of a circle's circumference to its diameter. While the average citizen can easily remember the 3.14 ratio, the exact ratio practically has an infinite amount of numbers. If you want a more precise pi ratio, it is 3.141592653589793238462643383279. How well do you think you could remember just those 30 digits? One man was able to remember the ratio of pi up to 70,000 decimal places. Rajveer Meena accomplished the feat on March 21, 2015 while wearing a blindfold. According to the Guinness Book of World Records, Meena's feat took nearly 10 hours to accomplish. According to Five-Thirty-Eight, there are now more than 22 trillion know digits to pi. According to Five-Thirty-Eight, it took a Dell computer nearly 105 days of computation to come up with the large number of digits. This is compared to just 2,000 known digits of pi in the mid-20th century. So how does one remember so many digits? Savant Daniel Tammet, who is able to remember pi's calculation to more than 20,000 digits, told David Letterman, "What I am doing is visualizing numbers." he said. "When you look at a number, you just see the numbers four and three. When I am looking at numbers, I am seeing different colors and shapes and textures. It is called 'synesthesia.' My brain is working in such a way I am looking and also experiencing color. It is two senses combined. "Having a more exact number of pi helps scientists at NASA conduct more precise experiments and calculations. Having more exact figures helps lend precision to projects such as landing rovers on Mars, sending spacecraft into deep space or tracking the movement of asteroids. To see many of the ways NASA uses pi, click 1746

There are a lot of myths circulating about COVID-19, the disease caused by the new coronavirus. Let's break the facts.The Centers for Disease Control and Prevention (CDC) says symptoms of COVID-19 include fever, coughing and shortness of breath. Symptoms can appear two and 14 days after exposure.Doctors draw comparisons to the flu.“Coronavirus is also interesting because it doesn't seem to be quite as infectious as common influenza,” said Dr. Shauna Gulley.Dr. Gulley with the large health system Centura Health has worked with coronavirus patients during this outbreak."Many of those people are quite well and have very minimal symptoms and do not need additional interaction with the health care system,” said Dr. Gulley. "We do believe in people that are, perhaps, older or have multiple medical problems such as diabetes or anything that makes your immune system weaker, that coronavirus may be more dangerous than influenza.”Dr. Gulley says it’s still unclear why coronavirus has been mild in children. She has advice on what people should do. "First of all, the worry about going and getting toilet paper, I don't think that should be first and foremost on anyone's list today,” said Dr. Gulley. While it’s important to be prepared, it’s important to not go overboard."We are seeing people come into our environments and take soap, masks and other supplies home to try to stockpile that in their homes,” Dr. Gulley said. "One of our hospitals actually had all of their soaps and hand sanitizers stolen last week."She also says people need to know how to use hand sanitizer."The myths around putting it on your body or on your face is where we get into trouble. Those things are not safe for people to do,” said Dr. Gulley. The CDC says people at a higher risk should avoid crowds. Dr. Gulley says it’s a good idea to keep your space."We believe that staying about six feet away from somebody with symptoms is the most protective space,” Dr. Gulley said.As the number of cases grows in the United States, public anxiety may be growing with it. So, don’t fear communicating if you’re dealing with another kind of medical issue.“If you're an allergy sufferer, I think it's important for you to talk to others about the fact that you have allergies and for them to be a little bit more assured that you're not infected. You have no fever, you have no deep cough and you have no risk factors for coronavirus,” Dr. Gulley said.If you are experiencing symptoms, call your doctor. 2494
