This landlocked state shouldn't have any islands. But the deadly flooding that has deluged parts of Nebraska could get worse before it gets better."This really is the most devastating flooding we've probably ever had in our state's history, from the standpoint of how widespread it is," Gov. Pete Ricketts said Monday.More than 8 million people are under flood warnings in the Midwest and the Mississippi River Valley, said CNN meteorologist Dave Hennen."Eastern Nebraska remains the hardest hit area, with much of the southeast part of the state under flood warnings," he said.The flooding has already killed two people in Nebraska and one man in Iowa. Ricketts said at least one person remains missing in Nebraska.Flood records have been shattered in 17 places, and more rivers will likely break cresting records this week, according to the Nebraska Emergency Management Agency. (A crest is the highest point of a flood wave.)Now the big concern is floodwater draining downstream, further deluging communities that can't take any more water.3 deaths include a farmer trying to rescue othersNebraskan James Wilke, a farmer in Platte County, used his tractor to try to help a person trapped in a vehicle, NEMA spokesman Mike Wight said."With the guidance of emergency responders, James drove his tractor over the Shell Creek bridge on the Monestary Road and the bridge gave out. James and the tractor went down into the flood water below," family friend Jodi L. Hefti wrote on Facebook.Another Nebraska man died after he was overcome by flood waters near a dam in Spencer, Wight said.He said one more person in Nebraska is missing and presumed dead.In Iowa, Aleido Rojas Galan of Nebraska was one of three people rescued from floodwater, Iowa's Fremont County Sheriff's Office said. But Galan, 55, succumbed to his injuries and died at a hospital in Lincoln.This nightmare started with a 'bomb cyclone' The mammoth flooding follows a powerful "bomb cyclone" that slammed the central US last week with hurricane-like winds and blizzard conditions.Melting snow ended up in rivers and streams, causing flooding and cresting days after the precipitation was over.Nebraska's Offutt Air Force Base, just south of Omaha, said about 30 buildings were hit with floodwater."Team Offutt has done an incredible job working together to battle this historic flood as best we can," said Col. Michael Manion, 55th Wing commander. On Sunday, he said the 2449

The Transportation Security Administration (TSA) screened fewer passengers Monday than it had in the past 10 years, a spokesperson says.According to TSA public affairs spokesperson Lisa Farbstein, department officers screened 154,080 people at checkpoints across the country on Monday.

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.

The Trump administration is coming out with new visa restrictions aimed at restricting a practice known as “birth tourism." That refers to cases when women travel to the United States to give birth so their children can have U.S. citizenship. Visa applicants deemed by consular officers to be coming to the U.S. primarily to give birth will now be treated like other foreigners coming to the U.S. for medical treatment. According to 445
