Explanation of the Plum Pudding Model

At the dawn of the 20th century, scientists knew that negatively charged particles existed. Because most atoms have a neutral charge, scientists thought that positive particles might exist to balance the negative particles. They were also curious about how many charged particles were in the atom and how the particles were arranged. Thomson proposed an atomic model in 1904 in response to these curiosities.
In Thomson’s "Plum Pudding Model" each atom was a sphere filled with a positively charged fluid. The fluid was called the "pudding." Scattered in this fluid were electrons known as the "plums." The radius of the model was 10-10 meters.
Thomson suggested that the positive fluid held the negative charges, the electrons, in the atom because of electrical forces. However, this was only a very vague explanation and failed to provide any definite answers.

The Story of La Befana

La Befana
Country of Origin: Italy




The Three Wise Men had traveled long and far in search of Bethlehem. One night of their journey they became lost, and came to the doorstep of the Italian Grandmother Befana to ask for directions.

Befana was consumed with the sweeping and cleaning of her home and quickly dismissed the Wise Men when they told her of their search for the New Born King. Even when they asked her to come with them to pay respects to Jesus, she stubbornly refused. Later in the night a brilliant star appeared in the sky, and it's beauty quickly made Befana realize she had made a terrible mistake.

She gathered up toys and presents for the Christ Child and tried to run after them, but her old legs couldn't catch up with them. In frustration, she wept over the dirty broom that had been her misfortune.

The sincerity of her tears gave the broom new life, and it scooped her up into the night sky to search for the Wise Men she had treated so badly. La Befana has never found the Three Kings or the stable they searched for, but every year on January 6th, the Feast of the Epiphany, she flies over the homes of the children of Italy leaving presents with good boys and girls until she finds the baby Jesus.

Starbucks In Trouble?

Starbucks in Trouble?

Starbucks testing $1 coffee, Free refills

Starbucks Corp is testing $1 coffees and free refills, The Wall Street Journal reported on Wednesday, as the global coffee chain faces increasing competition from fast-food rivals.

The report said Starbucks is experimenting with a "short" $1 cup as well as free refills for brewed coffee in its Seattle-area stores. Starbucks charges around $1.50 to $4.00 for a coffee, depending on size and flavour.

Starbucks was not immediately available for comment, but the report quoted the company's spokeswoman.

Shares in Starbucks have lost around half their value over the past year amid worries about U.S. consumer spending, over-expansion, and competition from fast-food rivals such as McDonald's Corp who offer specialty coffees.

The report said that $1 undercut regular coffee prices at both McDonald's and Dunkin' Donuts, a unit of Dunkin' Brands Inc., which start in the low $1 range.

Starbucks announced a management reshuffle earlier this year, bringing Howard Schultz back into the chief executive position. It also said it would close underperforming U.S. outlets and speed up international growth.

Starbucks has around 15,000 stores around the world including over 10,000 in the United States.
