question:
Verify if the sentiment of the following document towards the entity Chris Caldwell is Neutral . These primes are exceedingly rare and sporadic  said Chris Caldwell  a professor of mathematics and statistics at the University of Tennessee at Martin  who studies prime numbers and has written a history of the Mersenne primes.
"Finding a prime is not going to change any theorems in mathematics  but this is a type of prime that has been interesting to mathematicians since several centuries before Christ "  Caldwell  said. Even the ancient Greek mathematician Euclid talked about what would later become the Mersenne primes  he said.
 Caldwell  added that the discovery was akin to breaking a land speed record.
The last few Mersenne primes have been closer to each other than the researchers expected   he  said.
The numbers seem to occur sporadically because researchers don't fully understand the pattern they follow   he  said. "So you expect in any process that appears random to have some close groupings of numbers. But  we  didn't expect to find another one so soon after the last one."
"In the long run   we  hope to use these data to predict how often these occur "  he  added.
answer:
yes

 The remnants of Hurricane Nate  are delivering heavy but much-needed rain to portions of the Mid-Atlantic and Northeast on Monday.
"For some areas   Nate  will bring the biggest rainfall in six to eight weeks or longer â AccuWeather meteorologist Alex Sosnowski said. Nearly half of the northeastern U.S. was described as "abnormally dry" in the most recent U.S. Drought Monitor  so the rain will help ease the near-drought conditions.
 Nate  was downgraded from a hurricane to a tropical storm and finally a tropical depression on Sunday as it raced north after making landfall along the Gulf Coast.
 Nate  crashed into the Gulf Coast as a Category 1 hurricane Saturday near the mouth of the Mississippi River before making landfall again early Sunday near Biloxi  Miss. The hurricane was the first to make landfall in the state since Katrina devastated much of the Gulf Coast in 2005.
Overall   Nate  spared the region the kind of catastrophic damage left by a series of hurricanes that hit the southern U.S. and Caribbean in recent weeks. No storm-related deaths or injuries were immediately reported.
 Nate  was the fourth hurricane to hit the U.S. and its territories in 2017  following Harvey  Irma and Maria. That's most U.S. hurricane strikes since 2005  when five hurricanes hit land.
Although  Nate  knocked out power to more than 100 000 residents in Mississippi  Alabama  Louisiana and Florida  crews restored much of the power grid within 24 hours.
The Mississippi coast "took a hard hit from  Nate  " the Mississippi Emergency Management Agency tweeted on Sunday. "The lack of major damage is a testament to the strong and smart rebuilding since Katrina."
answer:
yes
