Expanding Universe

1. Explain what the balloon + dots represent.

The balloon represent the universe, and dots are represent which galaxies are moving farther and farther.

2.Which letter (s) moved the farther from M? Which moved the least.

The dots are closet from neck that are moved least, and the stars that farthest from neck is moved farthest.

3. Summarize the trend: movement of galaxies related to distance from M.

All of galaxies are moving farther and farther form M when the universe is expanding.

4. How does this experiment model what is occurring in our expanding universe? In what way does a balloon Not represent the universe.

This experiment model show that universe is expanding and, galaxies are moving farther and farther each other as universe expands. The balloon might pop, but universe not. The second, the one of endpoint of balloon is not expanding so fast like other part.

how electricity is transmitted to your home

Water  has  a potential energy, as water falls down the penstock, the potential energy is converted into kinetic energy, which is used to rotate the blade in turbine.  When the turbine starts to work, the kinetic energy becomes mechanical energy as the blades are rotating, and also activates the generator, thus the mechanical energy finally is converted into electrical energy.

hydro_85

The electric energy pass grid high voltage transmission line to terminal station, some for electric energy pass subtransmission lines. These energy can be sold transmission voltage to users of large amounts who own and operate their own substation. The other part of electric energy are through distribution substation to our home.

substation

     how this transmission process work

The hydroelectricity dam mad water fall down, and the potential energy change to kinetic energy.

Itaipu-dam

When the turbine starts work, the kinetic energy becomes mechanical energy as the blades are rotating, and also activates the generator, thus the mechanical energy finally is converted into electrical energy.

Hydroelectric-generator

Generators usually produced electricity with a low voltage, the low generator voltage is increased to a higher transmission voltage by a step-up transformer. When the electric energy arrive the terminal station, it would divide in two ways, one way is to customers, another way is to commercial, and small and medium industrial customers.

Short Story Rewrite

Never mind them watermelons

 

Peiran Qi

 

Well now, old Sam Gibb, he didn’t believe in ghosts. Not one bit. Everyone in town knew the old log cabin back in the woods was haunted, but Sam Gibb just laughed whenever folks talked about it. Finally, the blacksmith dared Sam Gibb to spend the night in the haunted log cabin. If he stayed there until dawn, the blacksmith would buy him a whole cartload of watermelons. Sam was delighted. Watermelon was Sam’s absolute favorite fruit. He accepted the dare at once, packed some matches and his pipe, and went right over to the log cabin to spend the night.

Sam went into the old log cabin, started a fire, lit his pipe, and settled into a rickety old chair with yesterday’s newspaper. As he was reading, he heard a creaking sound. Looking up, he saw that a gnarled little creature with glowing red eyes had taken the seat beside him. It had a long, forked tail, two horns on its head, claws at the ends of its hands, and sharp teeth that poked right through its large lips.

“There aren’t nobody here tonight except you and me,” the creature said to old Sam Gibb. It had a voice like the hiss of flames. Sam’s heart nearly stopped with fright. He leapt to his feet.

“There aren’t going to be nobody here but you in a minute,” Sam Gibb told the gnarled creature. He leapt straight for the nearest exit – which happened to be the window – and hi-tailed it down the lane lickety-split. He ran so fast he overtook two rabbits being chased by a coyote. After one minute, Sam was hi-tailed it down, and he saw a men who wear a hood was stay under a tree. Sam can’t saw him face, when he walk to him, that man asked Sam:” why are you running so fast?” “Because….because……”Sam panted. “Because there are a gnarled little creature is running after you, right?” “Why …why you know that.” Sam asked and afraid of looking at him. “Because, that’s me!!” The man putted up his head and opened big mouth. He turned on Sam like a tiger, and bite his neck.

“You’re making pretty good speed for an old man,” said the creature to old Sam Gibb, “but you can’t leave again!” Sam felt his body was pain like got fire. He can felt his blood was blowout from neck, he was despairing. “Oh my God! I will dead here!!!” Sam said it in his heart.

“Don’t touch me, I don’t want to die!!!!!!!” Sam exclaimed and opened eyes. He found that he was still at the old log cabin and the newspaper is still in his hand. “Oh my God, it just a dream.” Sam settled on the chair with a small sigh of relief. At this time, he heard a creaking sound. Looking up, he saw that a gnarled little creature with glowing red eyes had taken the seat beside him. It has the same appearance as the creature in his dream.

“There aren’t nobody here this dawn except you and me,” the creature said to old Sam Gibb, and its claw was griping Sam’s neck……

Force of Luck

This story is about two friends have a disagreement over whether it is money or luck that makes a man successful. To find out, they give $200 to a poor miller who works for a local mill. The money is taken from the miller by a hawk. When the men return, the miller tells them truthfully what has happened.

They give him another $200. The miller hides the money in a jar filled with grain, but his wife, unknowingly, trades the jar for whitewash. When the men return, the miller again tells them what has happened.

This time, one of them gives the miller a piece of lead. The miller gives the lead to a fisherman, who gives him a fish in exchange. In the fish is a piece of “glass” which turns out to be a diamond. The miller sells the diamond for $100,000 and uses the money to start his own business. The business prospers. When the men return, the miller takes them to his summer cabin. There, they find a hawk’s nest which has the original $200 in it. Later that night, the two men stop for the evening. When their horses are being fed, it is discovered that there is $200 in the bottom of the jar!

I think this story told us luck is more important than money, because the miller is luck that these whether men want to give him money and he got a diamond.
