3.1.6 Open and Closed Loop Systems

Describe an open loop system that has not already been given as an example. Could the system benefit from feedback? justify your answer.
            -a time bomb; It runs a clock down, then at 00:00:00 it lights a spark to ignight the explosives. yes, otherwise the bomb would require some one to press an ignition switch near the explosives, and sacrifice their life.

Describe a close loop system that has not already been given as an example. Describe the feedback utilized, and describe why that type of feedback is utilized.
            -a sismic bomb; when it senses vibrations, it lights a spark to ignight the explosives. The feed back, in the form of vibrations from infentry men or vehicals above ground are gaged to set off the bomb.

3.1.5 Variable Functions

Describe how you might modify the Plus command so that it can reset a variable block to 0 within a program.
           -change the (+) to a (-) so that it removes 1 on each loop

What might an industrial or manufacturing engineering need to count or keep track of? Describe one example.
           -what floor an elevator is on, a counting machine, or even a digital clock. They all need to add one over and over until the variable is equal to the desired number.
A Variable-Based System:

3.1.4 branch functions

1. Describe why is it important to include branches in programs.
       Because it allows a switch to change the path of a program

2. Describe an everyday application of a normally open switch that has not been given as an example.
       Circut breaker

3. Describe an everyday application of a normally closed switch that has been given as an example.
       doorbell

Edit: the flowchart includes an error. The final "no" arrow should redirect to "is it even or odd" instead ofo "choose a #." 

Car of the Future

So what is the car of the future? In other words, what appears to be the most promising technology explored by Click and Clack? Justify your response.
The car of the future would be fuel efficient, light weight, hydrogen powered, and must also be safe.


What fields of study/work would support the development of the car of the future. Describe two different ones.

• Fuel efficiency
• Safety
• Design

Ground Zero

What different "trades" (types of construction work) are featured in this video? Name at least three.

• Architecture
• Pipe work
• Concrete work
• Electrical

What aspect of the project is most interesting to you? Why is that?

The architecture was the most intresting aspect to me beacause they were able to find a way to build a giant tower that looks nice and modern, and at the same time it is very safe.

Smartest Machine on Earth

What is "machine learning"?
The ability for a machine to learn from it's mistakes. AI.
How did the IBM team employ that concept in the development of Watson's AI? What advantage did that provide over previous attempts at "intelligence"?
This "machine learning" gives Watson a real advantage over other machines because it can learn from it's mistakes. Ex: when Watson didn't get a context clue in a jeopardy question, and that caused him to get it wrong; in the following question he was able to analyze the question and get it right.
I've often mentioned the term "Empirical Scepticism". What does that mean? How does that relate to the concept of Machine Learning? How does this relate to your life?
Empirical Scepticism means to suspend judgement and to embrace doubt in order to work harder for a better result. This relates to machine learning because they saw doubt in Watson, but they worked harder to make him better.
