A Difficult Equation Charles Hsueh
Difficulties should be seen as challenges to strive towards, hoping that one day; one can defend, control and solve the unsolvable equation. Permanent sickness may be an everlasting nightmare as it can affect patients in many ways yet losing hope should never be on the list. Similarly in an encouraging film, “A beautiful mind”, inspired by true events of the main character, John Nash who is unfortunately a victim trapped in the darkness and cannot escape from its claw. The story starts before his psychotic break, where he uses his unbelievable talent in mathematics and understanding to its fullest. Not long after, Nash becomes hallucinated with imaginary peers who give out negative advices such as being a spy and kill his own wife for him to follow. As the Movie concludes, he represented the symbol of hope that seems to never give up even to a point where the disease cannot be fixed and instead he controlled it. This proves that even in the darkest times there will still be an answer to every equation. It is just in a matter of time. The film is in some ways, quite fascinating as it gives those who feel rejected from the society a sense of similarity and belonging through the effects of brilliance, illness and its illusions thus breaking all the barriers that prevent unity of all individuals.

To begin with, the film introduced brilliance of one whose thoughts and actions are different, thus it changes the society’s view on that particular. It is evident in the film that Nash has an outstanding talent and proved it by completing a remarkably high accomplishment in Howard without even attending a single class. He believes that classes can only destroy one’s creativity like a box full of conventions. Outside of the box, he walks yet only finds himself humiliated by surrounding peers. Similarly in nowadays, when one is unique or in another words, different among others, they find...

Difficult Conversations How to Discuss What Matters Most
Stone, D., Patton, B., & Heen, S. (1999)
New York, New York: Penguin.
ISBN0-670-88339-5
Outline of the Thesis:
General Subject Matter: Business communication
Theme: Communication during uncomfortable conversations.
Thesis: The author explores what makes some conversations difficult, why people avoid
having difficult conversations, and why people often managedifficult conversations poorly. The author then provides information on how to handle these situations.
Assessment of Author's Main Points:
What Happened
The “what happened conversation” is where most difficult conversation develop from. Most begin with some type of dispute of what transpired. They may agree on the basic facts but have different interpretations of what it means. The author suggests taking the “And Stance,” acknowledgment that both parties have a different takes on the situation. Next we should not make assumptions based of ones intentions. We often jump from the impact of the situation to the intent without asking for an explanation of their motives. Finally, in the “what happened” conversation we need to avoid assigning blame. It makes us lose focus on the problem and how to fix it. Instead concentrate on how all parties contributed to the situation. This emphasizes understanding causes, joint responsibility, and avoiding future...

...Difficult Customers
The customer leaned across the counter. “You mean I spend thousands of dollars in here, and I can't return a defective tool?” he said.
“Well, the tool isn't really defective,” replied the counter salesperson.
“So you're calling me a liar?”
The customer now had everyone's attention. His loud voice and aggressive manner caused some of the other customers to look at one another and roll their eyes as if to convey the silent message, Oh, one of thosedifficult people.
It was my first week at the counter, and I was leaning toward the customer's point of view.
My colleague continued the fight. “No, I'm not calling you a liar. This is simply normal wear of the tool. It's against the manufacturer's policy to refund for normal wear and tear.”
I was now completely on the customer's side.
The customer didn't reply immediately, and a silence fell across the room. He straightened up, slowly scanned the other customers, and said in a clear voice said, “People only come here as a last resort.”
He turned on the heels of his work boots and marched out of the store. As soon as the door closed, you could feel the air come back into the room. People chuckled rather nervously. Someone said, “Guess it takes all kinds.”
“That guy's always a pain,” said my co-worker.
And that was the real issue. A different customer would have received a new tool, no questions asked, but because this particular customer wore the...

...determine the bulk velocity of the stream using Equation 1.
(Eqn. 1)
Where is the flowrate in m3/s and A is the cross-sectional area of the pipe. To find the flowrate, we multiply the flowmeter reading by the constant
and convert from gallons to cubic meters as follows:
The cross sectional area of the 7.75mm pipe is
Plugging these values into Equation 1, we obtain a bulk velocity .
With the bulk velocity value, we can find the Reynolds number of the flow using Equation 2.
(Eqn. 2)
Plugging in known values to Equation 2, we find:
The experimental friction factor of the pipe can be calculated as:
(Eqn. 3)
Using the pressure drop for the chosen sample from smallest smooth copper pipe across the known distance L, we obtain an experimental friction factor
The theoretical friction factor for smooth pipes can be calculated with the Petukhov formula:
(Petukhov Formula)
Using this formula with our calculated Reynolds number yields a theoretical friction factor of
Because Pipe 4 is a rough pipe, this Petukhov Formula does not apply and we must perform additional sample calculations. From the first data point for the fourth pipe we obtain the following flow properties:
Using Equations 2 and 3 we can find the following Reynolds number and experimental friction factor:
The theoretical friction factor for a rough pipe can be found by calculating the parallel...

...Difficult People Analysis
1. In the beginning-part plot outline, Pyotr is a frustrated youth who strives to balance his financial expenditures to that of the amount of his father's low income. The effort to consume father's pension for Pyotr's schooling creates a serious doubt to the financial security of every member in household. Pyotr's father is a disappointment to the family, his anti-social behavior has subdued the family into a state of fear and panic at the harsh tone of his voice.
In the middle-part plot outline, Pyotr now fantasizes about the possibility's of leaving the farm and walking the eighty miles North to Moscow. He would establish a capacity for impunity to the family's grief of a missing son. Pyotr will be inspired by a sole motivation, the relentless three day walk to Moscow. The journey will submit a stream of inevitable consequences as a cause of starvation, frostbite and fatigue, the ability to overcome this torment to the physical appearance would only better saturate the mental ability for perseverance and determination to reach the destination.
The final logic of plot that must be explained at the end of the story is Pyotr's confrontation with his guilt-ridden, contemptuous father before he leaves for Moscow. The intent to reconcile father's financial loss is expressed through Pyotr's coaxing rhetoric and judgemental approach to his father's daily attitude at the table. Finally, the room is brightly lit, not by the...

The short story Cold Equations by Tom Godwin takes place on a ship called EDS. The space cruiser is piloted by a man named Barton. He has an order of killing the stowaway who snuck onto the ship because the weight on the EDS is too much for the ship to handle. In the process of hunting down the stowaway, he realizes it was a young innocent girl named Marilyn. Once Barton understands what kind of person Marilyn is, he doesn’t kill her immediately because he knows her reasons were pure. Marilyn only wanted to see her brother, Gerry, again after ten years of being apart and was ignorant to the fact that her life can end with the decision of sneaking onto the ship. Barton begins to feel compassion after being with her and tries to comfort her, but knows what her fate is. He lets Marilyn live long enough to let her speak with Gerry once more before he follows through with the command. After Gerry and Marilyn speak he ejects her out into space. The ending was logical and no other endings would be possible because one the equation that was calibrated delicately, and two Barton could not throw the out the fever serums because that is the main reason for going on the trip to Woden.
A theoretical ending of Cold Equations could have been that Barton sacrifices himself for Marilyn, but since she is lighter than him, the fragile calibrated equation would be disrupted due to the change in weight. On EDS everything on ship is...

...There are now two separate equations: 60 = 6b - 6c and 60 = 3b + 3c
Solve both equations for b: b = 10 + c b = 10 - c
Now make both equations equal each other and solve for c: 10 + c = 10 - c 2c = 0 c = 0
The speed of the current was 0 mph Now, plug the numbers into one of either the original equations to find the speed of the boat in still water.
I chose the first equation: b = 10 + c or b = 10 + 0 b = 10
The speed of the boat in still water must remain a consistent 10 mph or more in order for Wayne and his daughter to make it home in time or dinner.
My Solution: c = current of river b = rate of boat d = s(t) will represent (distance = speed X time) Upstream: 60 = 6(b-c)
Downstream: 60 = 3(b+c)
There are now two separate equations: 60 = 6b - 6c and 60 = 3b + 3c
Solve both equations for b: b = 10 + c b = 10 - c
