Problem: (CNN) -- Floyd Mayweather Jr. has said he is ready to make the big-money fight with newly crowned WBO welterweight world champion Manny Pacquiao happen. 

After victory in Las Vegas over Puerto Rico's Miguel Cotto on Saturday, Pacquiao's trainer Freddie Roach said the "whole world" now wanted to see a fight with Mayweather. 

Reacting to the proposition the undefeated 32-year-old, who formerly held the WBC title at welterweight, told British broadcaster Sky Sports: "If he wants to fight Floyd Mayweather all he has to do is step up to the plate." 

The twice-voted Ring magazine fighter of the year added that he felt Pacquiao's approach was one-dimensional but the Filipino would be a favorite with the crowd. 

"The thing is with Pacquaio I don't see any versatility as a fighter; he's a good puncher but just one-dimensional. Is Pacquiao the greatest? 

"The world's going to go 'wow' if Floyd Mayweather gets beaten. That's what everyone is looking to see. 

"If I beat Manny Pacquaio do you know what they are going to say? 'You are supposed to beat him, you are Floyd Mayweather, you are the bigger man'. If I knock him out they'll say 'you're supposed to knock him out he's been knocked out before'. 

"I'm in a no-win situation and when I beat him no one is going to be surprised because he's been beaten before; whatever I do to Pacquaio has been done before - he's been beaten on three occasions. And if I knock him out I don't want the world shouting because he's been knocked out twice before."

Problem: In economics, the Gini coefficient (sometimes expressed as a Gini ratio or a normalized Gini index) is a measure of statistical dispersion intended to represent the income or wealth distribution of a nation's residents, and is the most commonly used measure of inequality. It was developed by the Italian statistician and sociologist Corrado Gini and published in his 1912 paper "Variability and Mutability" (). 

The Gini coefficient measures the inequality among values of a frequency distribution (for example, levels of income). A Gini coefficient of zero expresses perfect equality, where all values are the same (for example, where everyone has the same income). A Gini coefficient of 1 (or 100%) expresses maximal inequality among values (e.g., for a large number of people, where only one person has all the income or consumption, and all others have none, the Gini coefficient will be very nearly one). However, a value greater than one may occur if some persons represent negative contribution to the total (for example, having negative income or wealth). For larger groups, values close to or above 1 are very unlikely in practice. Given the normalization of both the cumulative population and the cumulative share of income used to calculate the Gini coefficient, the measure is not overly sensitive to the specifics of the income distribution, but rather only on how incomes vary relative to the other members of a population. The exception to this is in the redistribution of wealth resulting in a minimum income for all people. When the population is sorted, if their income distribution were to approximate a well-known function, then some representative values could be calculated.

Problem: (CNN) -- The surviving pilot of Virgin Galactic SpaceShipTwo told authorities he was unaware the feather system had been unlocked early by his co-pilot. 

The spaceship disintegrated 45,000 feet above the Mojave Desert on October 31, killing co-pilot Michael Tyner Alsbury and injuring co-pilot Peter Siebold, who managed to parachute to the ground. 

Siebold was interviewed last week by the National Transportation Safety Board. He described being "extracted from the vehicle as a result of the break-up sequence and unbuckled from his seat at some point before the parachute deployed automatically," according to a release from the NTSB. 

Earlier this month, the NTSB tweeted that Alsbury "moved the lock/unlock handle into unlock position." 

...the copilot, who was in right seat, moved the lock/unlock handle into unlock position; he did not survive accident. #SpaceShipTwo 

But that mishap alone doesn't explain why the feathering started, since no one moved the feathering handle. 

During feathering, two pieces on the back of the vehicle -- the "feathers" -- lift up perpendicular to the spaceship, making the vehicle look as though it's arching its back as it descends. 

The wreckage has been recovered and will be used for follow-up examinations.
