Technology has many benefits towards people, most positive. Travel is easier and faster and medicine is leaps and bounds ahead of where it was even fifty years ago. With the power of technology, someone can get in their car and be able to find any location on the planet because of satellites. Technology has made a positive impact on people, it has made transportation more enjoyable and also significantly easier for people to get help with their daily health needs. In the story “Cold Equations”, by Tom Goodwin, there is space travel.…
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…
The short story “Cold Equations” by Tom Godwin is about human nature versus reality, because the girl’s nature told her to get on the EDS as a stowaway, but she didn't know the reality so she suffered the ultimate consequence of death. The EDS pilot knew he wasn’t alone in the EDS because of the heat sensor. He knew what he had to do, so he opened the cabinet where the human was. The pilot is surprised to find a young happy girl in the cabinet and gets thrown off his objective. He tells her what he has to do and she finds this news particularly upsetting.…
Cause and Effect on The Cold Equation In the story "the Cold Equation" by Tom Godwin, the author created a cause and effect relationship by having Marilyn decide to stowaway on the emergency dispatch ship that only has enough fuel for one person. Because Marilyn decided to stowaway she ended her own life, forced Barton to deal with having to kill a woman, negatively affects the results of the mission to Woden, and for her parents and brother to deal with her death. Marilyn's last moments of her life created an element of suspense in the story. In addition Marilyn's death has an effect on the reader and the characters.…

While it is true that the field of thermodynamics can be complex,1-8 the basic ideas behind the study of heat (or energy) transfer remain simple. Let us begin this study with an ideal solid, S1, in an empty universe. S1 contains atoms arranged in a regular array called a "lattice" (see Figure 1). Bonding electrons may be present. The nuclei of each atom act as weights and the bonding electrons as springs in an oscillator model. Non-bonding electrons may also be present, however in an ideal solid these electrons are not involved in carrying current. By extension, S1 contains no electronic conduction bands. The non-bonding electrons may be involved in Van der Waals (or contact) interactions between atoms. Given these restraint, it is clear that S1 is a non-metal.…
Two systems are said to be in thermal equilibrium with each other, if they are at the same temperature.…
When an Exothermic reaction occurs, energy is put into our surroundings. Creating a chemical bond releases energy, which makes it an exothermic process. Exothermic reactions usually feel hot, which means it is releasing heat into our surroundings.…

Its name stirs the imagination... Titanic. The unsinkable ship. The unimaginable catastrophe. The untold stories that lay in mystery two and a half miles beneath the waves of the North Atlantic. What buried tale of love, bravery, treasure and treachery, hidden by time and tragedy, waits here to be discovered? A beautiful socialite. A penniless artist. A priceless diamond. A romance so passionate that nothing on earth could stop it. A destiny so incredible that no one could have imagined it. A collision of lives that could only have happened on Titanic, the ship of dreams. The secrets are about to unfold...…
Thermochemistry Heat of precipitation - precipitate is unsoluble salt - precipitate must be prepared through double bond decomposition or precipitation method Do you still remember what is meant by double bond decomposition? [please refer to salts notes] General equation double bond decomposition/precipitation; Ionic equation for precipitation reaction. Salt Solubility in water Li+, Na+, K+, NH4+ All salt dissolve in water…
Nozzle Flow - Steam Steam at 1.5 bar and 150 deg C enters a nozzle at 10 m/s and exits at 1 bar. Assuming the flow is reversible and adiabatic, determine the exit temperature and velocity. If the exit nozzle area is 0.001 m2, evaluate the mass flow rate of the steam through the nozzle. P1 = 1.5 bar T1 = 90 deg C V1 = 10 m/s A2 = 0.001 m2…

Why I Chose to work in Aviation. We were sitting in a trailer, another long shift almost over, ready to go home after days of being awake and monitoring the skies. Suddenly, there is an alarm. Nothing new, alarms happen quite often, we knew how to react. The alarms didn 't just dissipate, they became louder and more intense. Things were beginning to get serious. We set off the flashers on buildings, got the f15 teams ready to deploy and started weapons launch procedures. There was one single plane coming in, flying towards what we were there to protect. This plane made it to the point where I had my finger on the launch button, which would have sent missals up and destroyed it, debris would have fallen and possibly killed civilians and definitely damaged property. The pilot finally turned off his flight path and landed when the f15s guided him down. It turns out it was just the governor, out for a joy ride, thinking that the law did not apply to him.…
