Newton's three laws & me

Energy Efficiency

III.

1. An object at rest will stay at rest unless an unbalanced force acts upon it.

2. Force equals mass times acceleration.

3. For every action there is equal and opposite reaction. 

An example of the Newton's first law of motion reminds me of a small example such as cleaning. Coming home from a long day of work or school, there are used paper towels and napkins sprawled across the living room and kitchen, as well as dishes getting familiar with utensils in the sink. Though I notice that the apartment is clearly untidy from a post-lively night scene, and in need of a good swipe and wipe, I can easily ignore these issues as I go about my day. Allowing them to accumulate just a little more dust while resting around. As the atrocities pile up and soon to creep around the back of my head like an itch, it is only then, the cleaner (the unbalanced force),  moves the object out of it's resting state to another- as it's act upon the mess with the intent to become tidy again. 

     Newton's second law of motion states that force = mass x acceleration. To remain in the idea of cleaning, one can easily give a resting, used paper towel a good crumple into a compacted ball, following with a toss into the trash bin. "Swish." 

The equally proportionate balance of this mass mixed with it's acceleration leads to the force of it's following successful Kobe shot. 

     Newton's third law of motion reminds me to always keep my helmet visor down while riding in the streets or highway/freeway. While it is certain to say that cruising at a safe speed will keep me at bay, there are opposite reactions flying behind as I pass by the many miles of the road. The force of another driver's tire of their vehicle moving at a their own speed causes an opposite reaction of debris such as pebbles and gravel to ricochet backwards, flying towards an equally approaching item (myself). 

Energy efficiency has become a popularized sector in everyday products that we all use today. Home appliances, light bulbs, and even vehicles are examples of good which put this practice forward into good use. In it's efforts to cut down waste and effectively provide full functionality, these modern-day items such as LED bulbs and electric motorcycles are the start to a booming generation of creating more "cleaner" or "smart" items to a better future. I hope to live to a point where I can say how the beginning of energy efficiency was a "thing of the past" and ideas such as solar panel windows are a general norm to society. 

I cannot blame Descartes to be wrong for birthing the thought of animals not containing a soul or intelligence, because of how simple individuals lived back in the 1600's. The observation may have been a subjective experience rather than a blown-out objective research because of their basic understanding of animals. I am sure to believe that if Descartes lived in a time where the study of animals have been explored thoroughly, he could have thought differently. Aside from his controversial points, Descartes was an important philosopher of our time, influencing many following ideologies up till today. His work has undoubtedly contributed to the process of human thought, as name lies solid in the timeline of philosophy, as well as mathematics such as algebra and geometry.
