What does engineering mean to you and how does it affect your life?
Engineering is defined as the use of mathematics, science, and technology to create products and systems that improve the world. But to me, it's so much more than a simple sentence of mere words. Engineering is about solving problems creatively. Engineering is practically anything and everything. It's a way to leave a mark on this world. Whether it being a better designed but already invented contraption, or something completely new and innovative, people will remember you, or at the very least use something you made everyday. That's what engineering means to me.
Engineering affects my everyday life, because it makes my life what it is. The desks I sit in at school, the cars I sit in to go places, the house I live in, the bed I sleep in, and many others were all designed through engineering. Someone had to sit down and think about what would make everyone's life better. All those engineers have made us live the way we do. We can travel to wherever we want, using a bridge, or a plane, a boat, or any other sorts of means of transport are all designed by engineers. Engineering has affected my everyday life, for the better, by being almost every part of the map.
All in all, engineering is much more than we realize. When someone says engineering, many people think computer engineering, electrical engineering, or green engineering. However, what many do not realize is that engineering is all around us. Everything has been designed for the better by an engineer. If it weren't for engineering, there would be no technology advances, and we'd be living like animals in the jungle or plains.
Why do humans design?
Humans design in order to improve their daily life by solving problems, and helping them adapt.
Who are design professionals and how do they contribute to society?
Design professionals are those who work on designing items, including professions like engineering, architecture, and graphic designer. They contribute to society by bringing new products into the market, and they are responsible for everything you have.
How did the Industrial Revolution shape the world as we know it?
The Industrial Revolution shifted the world to lean more towards designing nonagricultural products. This involved cities to become much more popular and thus made the world the way it is today.
How were the early engineering societies established?
They were established due to engineering becoming much more popular, and machine tools and interchangeable parts were in massive demand.
Why did engineering societies develop standards?
Standards were used to set everything the same no matter where you are in the world, because it became quite a problem when not everyone was using the same thing and you had to hunt for the parts you were looking for.
What are the greatest engineering achievements of the twentieth century?
The greatest achievements were mainly based around electricity, with things like the internet, computers, and of course, electricity, itself.
What are the modern engineering professions?
Modern engineering professions include civil, mechanical, industrial, electrical, and computer engineering.
What is the relationship between science and technology?

What is human factors (ergonomics)?
Ergonomics is the application of the knowledge about human physical characteristics, behavior, and abilities to design products, systems, or environments, for safety and effective use.
Why is it necessary to understand human factors to be a successful designer/engineer?
It is necessary to understand human factors to be a successful designer or engineer, because it allows you to pick a specific audience to target as well as advertise, and keeps it safe and efficient for the intended user.

How are principles of human physical characteristics, behavior, and abilities applied during the design process?
The principles of human physical characteristics, behavior, and abilities are applied during the design process in order to keep the product safe, so that no part of the body is kept at an awkward position that can leave injuries, and allows them to understand what feels natural to keep the product comfortable.
How can universal design principles help everyone?
Universal design principles help everyone because a universal design is made to benefit everyone, so the principles applied behind it are used to benefit or help practically everyone unless specifically designed for a target audience, especially one that's part of the minority.
What steps are used to do human factors design?
First step is to investigate and research, where you identify the problem and you begin to take on different angles and perspectives. Then you generate as many solutions to this problem as possible, as there are no wrong answers. After that, you evaluate and consider each solution and design until you pick one that best fits the parameters, as well as other important characteristics. From there you build a prototype following the blueprint. After that comes testing, to see if this design is the best it can be. Lastly, you evaluate the design again and see what you can make better,
How is a design evaluated for safety, comfort, and effective human use?
A design is evaluated for safety, comfort, and effective human use, by first considering if the measurements will fit the target audience, and then having the prototype tested by those especially of the target audience. After observing several different people use it, it should be clear as to what could be potential dangers.

7. What was your impression and perspective/comments on the trip?
I found the trip to be rather interesting. Walking around a plant was something I hadn't done before. Although it was nothing like I imagined it to be, I think it is a good experience to really understand how factories and plants like these work. Of course, it had some downsides, it didn't look very pleasing with the dim lighting and rather old building. The smell was almost unbearable. I'm sure many would not appreciate this kind of experience, however I found it interesting and much needed to grasp the factory and plant work life which is one many lead.

The article, "Light-bending silicon chip shows projector potential", talks about new ways to project images. Currently, our projectors use bulky and expensive lenses to display an image. However, with this new chip it would eliminate a lot of the cost and the unnecessary bulk of our traditional projectors. This new chip uses the coherence of light to bend light waves without any mechanical movement. In order to project the image, it changes the timing of the charged light waves where the waves will converge and amplify the strength at certain points. When they combine coherently in the air, they will form a single light beam and a spot on the screen. The mechanism isn't even slow in the slightest and keeps up with projectors. Although this one is made of silicon, the team is saying other semi-conductors can be used each better at projecting different things. The silicon is especially useful for infrared light. They are also looking to implement this into phones but lots of other products as well considering it cuts the cost by a significant amount. All in all, this new technology will lead to much cheaper electronics in the future.
I chose this article because I had found it interesting. Whenever new technology shows up, it always grabs my interest because I find it hard to imagine that you can further perfect certain technologies. I thought our projectors were fine as they were but this article brought up ways to improve it. I never really noticed how bulky lenses can be and how much larger or more expensive it makes it. Each new technology that appears brings us closer to the future many of us imagine. One where our current technology is cheap and affordable. But there would be further advanced technology, like something from out of a sci-fi movie. That's why I chose this article.
The full article is here.

Many complained that they had absolutely zero time for their family, thus the company was at the top of the priority list.
3. Name one aspect/philosophy the Japanese implemented from the Americans in the video "Gung Ho".
The Japanese loosened up a little on their very tight idea that the company comes first. Workers were allowed to have some personal time.
