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

The Trump administration is waiving federal contracting laws to speed construction of a U.S.-Mexico border wall, moving the president closer to fulfilling a signature campaign promise in an election year but sparking criticism about potential for fraud, waste and abuse. The Department of Homeland Security said Tuesday it'll allow 177 miles of wall to be built faster in California, Arizona, New Mexico and Texas. A 2005 law gives the Homeland Security secretary sweeping powers to waive laws to expedite border barrier construction. Last week, the Trump administration announced that .8 billion in funds appropriated by Congress earmarked for defense projects would be diverted toward funding the border wall. Nearly .5 billion of those funds were intended for projects earmarked for the National Guard, while the rest was intended to be spent on replacing aircrafts and ships. 896
