Tom: Hey everyone, it is Monday, March 14. I am Tom Hanson, and Channel One News starts right now.

You may have noticed a little time change yesterday as we lost an hour of sleep for daylight saving time. Okay, so here is a question for you. True or false: daylight saving time was created to help farmers get their harvests in. The answer is false. Actually, farmers hate it, and they are not alone. Arielle Hixson has the breakdown of why some people want to get rid of it.

Arielle: Some people like the change.

Man: We have more daytime, so that’s cool.

Arielle: Others, not so much.

Man: It is kind of annoying to just wake up and realize you don’t have that time back.

Arielle: So why do we do it? Well, it all started back in the 18th century, when Benjamin Franklin suggested the idea as a way of taking advantage of the sun’s rays and saving money on candles and oil lamps, two of the ways people could light their homes.

Congress first put the U.S. on daylight saving time during World War I to save energy and then again during World War II. But it wasn't until 1966 that Congress passed a uniform federal daylight saving time law.

Now, daylight saving time does mean more sun, like you can see right now. And that is a signal that spring is just around the corner. But some people argue that the practice is outdated. Lawmakers in California, South Dakota, Missouri and Rhode Island are considering getting rid of it. Hawaii and most of Arizona already don't do it.

And there are studies that back their argument. Some show that energy use actually went up in most cases, instead of down. Also, there is an increase in traffic accidents in the morning just after the time change when drivers are still sleepy and can't see as well in the dark. And daylight saving time may be linked to higher risks of stroke and other health problems.

And, though it is a popular myth, farmers hate it because it actually disrupts their schedule. But on the other hand, scientists found that increased daylight is actually good for young people, improving their activity levels. And some experts say it is good for the economy. When there is more daylight, people are out more spending money at shops and restaurants, stimulating the economy.

1 | P a g e For now, we all have to bear with the time changes, but there are some ways to help your body adjust quickly over the next few days. Avoid stimulants like caffeine. Don't eat heavy foods or use electronics, like smartphones, right before bedtime. Make sure your bedroom is dark and quiet. And spend at least an hour in the sunlight today to let your body's internal clock adjust.

Oh, and one more thing, embrace the warm weather, flowers and sunshine because it will be a good eight months before we get that hour back.

Tom: All right, after the break, Russia's sports teams are in trouble and on thin ice, possibly being banned from the Summer Olympics.

Tom: Let's get you caught up on some other headlines. We have got five months until the Summer Olympic Games in Brazil. And right now Russia's Olympic athletes are in serious jeopardy of being banned after a widespread doping scandal.

A speed skater, weightlifter and volleyball player — all Russian — all tested positive for meldonium. Russian tennis star Maria Sharapova made the little-known drug a household name when she admitted to using it last week.

Maria Sharapova: I made a huge mistake, and I — I let my fans down.

Tom: Meldonium is a heart medication, available over the counter in Eastern Europe, known for boosting endurance by increasing blood flow. Ninety-nine Russian athletes have failed the drug test so far, and it comes as Russia is accused of running a state- sponsored doping program.

On Friday the International Association of Athletics Federations moved to extend a ban on Russia taking part in international competition, raising fears the country might miss out on the Olympic Games.

Next up, Nancy Reagan was laid to rest at a private funeral service on Friday. The former first lady was remembered for her style, grace and devotion to her husband, the 40th president.

Ron Reagan: There likely wouldn't have been a President Ronald Reagan without a Nancy Reagan.

Tom: Nancy Reagan's children, Ron and Patti, shared moments of their mother. Watching from the front row were a former president and four women who know what it is like to be first lady. Other celebrities and politicians were there as well.

2 | P a g e She was best known for her unflinching support of her husband, President Ronald Reagan, and for her "just say no" to drugs campaign.

Michelle Obama: Mrs. Reagan reminded us of the importance of women's leadership at every level of our society.

Tom: Her final resting place is on the grounds of the Reagan Presidential Library in Simi Valley, California, right by her husband's side.

Over the weekend Japan marked the five-year anniversary of the earthquake and tsunami that left more than 18,000 people dead or missing. Prime Minister Shinzo Abe of Japan took part in a moment of silence at the exact moment the quake hit. Millions across the country did the same.

The earthquake on March 11, 2011, was one of the most powerful ever recorded. The 9.0 quake struck offshore and created a vast water surge, or tsunami, that devastated the northeast coast.

It also triggered a nuclear disaster at the Fukushima Daiichi nuclear plant. Water overran the nuclear plant, which set off a series of meltdowns. The disaster spewed radiation over a wide area, forcing more than 160,000 people to be evacuated. Five years later, most have not been able to return to their homes, and more than 2,500 people are still unaccounted for.

All right, after the break, we have got a story about a number that never ends, no matter which way you slice it.

Tom: All right, it is time to get your geek on because today is 3-1-4, and for all you math and science nerds, it is practically a holiday — a date to celebrate the mathematical constant pi.

Happy Pi Day, everyone. Pi Day is celebrated every March 14, in honor of 3.14, the first three digits of the mathematical number pi. It is the ratio of the circumference of a circle to its diameter. But what makes pi so interesting for math geeks? Well, it is an irrational and transcendental number, which means it goes on forever with no repetition or pattern.

And to see how schools celebrated Pi Day last year, head on over to ChannelOne.com. And be sure to submit your own videos to [email protected] if you guys are doing something cool.

All right, now, from math to science, pi is used in so many ways, and Maggie Rulli is here to introduce us to one kid who probably uses it a lot.

3 | P a g e Maggie: Yeah, well, a Los Angeles student is proving that he is among the smartest in the world. The senior earned a perfect score on one of the most difficult college-level exams, and that is not all.

Cedric Argueta is counting up his accomplishments.

Cedric Argueta: I don’t like making mistakes. I don’t.

Maggie: Of the more than 302,000 students around the world who took the advanced placement calculus test last year, he was 1 of only 12 who achieved a perfect score.

Cedric: I like the absoluteness of math — that there’s always an answer.

Anthony Yom: To get a perfect on the AP exam, I think it takes a special skill set.

Maggie: Anthony Yom is Cedric's teacher at Lincoln High School. The son of Korean immigrants, Mr. Yom now inspires students in a school that might not look like it inspires much greatness — old, with grates on the windows, in a tough neighborhood in East L.A.

Yom: Today is all about making your life easier.

Maggie: His approach to teaching goes beyond calculating the slope of a curve.

Yom: One of my strategies is really to make sure to provide that environment where kids are not shamed of asking questions.

Maggie: Mr. Yom makes Cedric and the rest of his class meet after school, on weekends and even holidays.

Cedric: His style of teaching commands respect, and his personality is very likeable. He gets to know his students on a personal level.

Maggie: All the hard work paid off not only for Cedric but also for the entire class.

Yom: It's not always fun, but I do know for sure once they get the score, and if I ask them, “Hey, was it worth it?” they — every single one of them say, “It was so worth it.”

Maggie: For three years in a row, every student that has walked into Mr. Yom's class has passed the AP calc test.

Yom: They know that I sincerely care about them, and it’s felt for them.

Maggie: Mr. Yom and Cedric were both honored by the L.A. school board, and President Obama even invited Cedric to the White House science fair. The 17-year-old wants to go to Caltech and become a rocket scientist…

4 | P a g e Cedric: Just need to try hard, work hard, and you'll get good at it.

Maggie: …while Mr. Yom's focus is on his next batch of calc students. Maggie Rulli, Channel One News.

Tom: Thanks, Maggie.

All right, guys, we are all out of time. We will see you right back here tomorrow.
