In this article, the writer Dylan Mattews depicts a soviet officer Stanislav Petrov who stopped a nuclear war from happening. Petrov and his crew had a warning sign of ICBM missiles launched by the USA towards the Soviet Union. There were two choices for Petrov to make, report it and start WW3 or not report it and run the risk of being nuked. Eventually, Petrov and his crew concluded that it was just a false alarm, which thankfully it was. Turns out the alarm was triggered by the sun’s reflection on the clouds, making it seem like there was an incoming missile. I like this article because I enjoy learning about history and interesting things that have happened in the past. I heard about this story a while ago but this article conveyed the thoughts I already had about this story. This man single-handedly stopped a nuclear war and the possible complete annihilation of the human race as we know it.

care of ethics

Care ethics is a personality trait that is needs to be practiced over time and with enough labour can help shape the world around us for the better. In order to create an ethics people who, have a good understand of the concept and that have experience in situation in which its needed. They can teach others how to act by explain to them or more importantly show them through their actions. The people can slowly learn how to use care of ethics in day to day lives. We would have to believe in environment having the same power and can equally affect us and we affect it. We need realize that we just can’t just abuse the environment and walk away and think nothing bad is going to happen. We would help preserve our ecosystem by not littering and using proper bins when throw away something. Or helping on a humanity scale by donation to a charity or going out to volunteer and help the not so fortunate. Some benefits of everyone adopting care by ethics is our environments and communities will be a lot safer and clean but on the other hand it will set a high standard for everyone and that just can’t happen because no one is perfect. I think we can try the best we can to adopt care of ethics, we can’t be perfect, but we can do our part to help the environment.

Ethics of care towards the environment would look like people treating the environment with respect and not to leave it worse for wear and destroy it.

In this article, Amazon employment are threatening to walk out of Amazon if they don’t help to reduce the growing problem of climate change. This article interested me because it illustrates how everyday working people are taking a standing against climate change and how they are going about doing that. Amazon employees have pushed Amazon into starting a program called the Shipment Zero program in which Amazon has promised to make 50% of their shipments net zero by 2030. Even with that, Amazon employees have continued to put Amazon to be more environmentally friendlier. They have done this by making a climate change plan for the company, which Amazon’s shareholders voted down. The author Shirin Ghaffary conveys the frustration of the Amazon employees by going very in depth about how and why the employee are upset and what they are doing about it. I made a personal connection to this article because I know what it feels like to be in a situation where, I the employee is upset with the manager and how the company is poorly treating its staff. I believe this article can show how people working for big companies can make a change and help to become more environmentally friendly and be the leaders in the fight against climate change.

Wave Phenomena Part 1

This video shows us constructive interference. Constructive interference is when two crest or two trough waves hit each other causing the two waves to become bigger and combine for a second then go back into two separate waves.

This video shows us destructive interference. Destructive interference is when a crest wave and a trough wave hit each other causing the wave to cancel out and become still just for a second then separate into two waves.

This video shows us standing waves. Standing waves is when two interference waves have the same amplitude and wavelength, causing the wave pattern and creates point where they cross called nodes.

Thermos Challenge

Our goal for this project was to create a thermos from cheap materials totalling to no more than $3. To create an efficient thermos, applications of our energy unit are necessary. Mine and Ethan’s thermos was simple and flawless in theory, to begin with, we took a Styrofoam cup and lined the inside with tin foil and created a lid out of tin foil and cotton fabric, these were the main functional components of the first prototype, as an additional aesthetic piece we painted it black. this thermos did not work well because it had a lack of insulation on the outside.

Considering the poor results of our first thermos we decided to ditch the aesthetic of the paint and replace it with more insulation because to us functionality was more important, we used the same lid but replaced the paint with a layer of foam underlay which was the best insulator available to us

Our second thermos was our best performing thermos but it had one key issue in the fact that it was over budget by 45 cents, so we exchanged some of the tin foil for a cutout from a pop can which was less reflective but way cheaper at the same time, the outer layer of the second one was perfect so we kept that largely untouched besides using some of our freed budget to insulate the top better, these elements left us with our third and final thermos.

Despite this being our final product it was not our best performing, but it was our most cost effective thermos, the next worksheets outlines what we used in and how we performed the testing experiments and the over all results of all 3 thermoses.

Now, the most important part, the theory behind our design and why we believed it would work. I think it is worth mentioning that our thermos was the best performing thermos that only used materials found in class when taking into account the over all price of our final product. Our design is simple and focuses largely on keeping the heat inside by using reflective and conductive materials, if the inner layer is able to conduct heat well it will create a system where the water heats up the foil and then in turn the foil does the same to the water. of course because of the laws of energy conservation this does not work that perfectly in practice because the water must share its energy with the foil to heat it up causing the water to cool down slightly, and the foil will also share its energy with the insulators. Due to these reasons you put the conductor on the inside because it takes less energy to change its temperature so the water will lose minimal energy creating stable temperatures, in turn you keep the insulators on the outside because they do not conduct energy well so they aren’t good at introducing the high energy of the inside of the thermos to the lower energy air outside. This is good because the hot water would balance its energy with the air faster if it had easier and more direct contact.

Post Writing “Totem”

Canadian identity has been changed from first nations identity, to early Europeans who colonized the land. When people think of Canada, they think of hockey, maple syrup and snowy weather. But, what should be included is the first nations. When talking about Canadian history it is often overlooked is the history before early Europeans came over and settled. This was a very tough time for first nations because the early setters were trying to get rid of them and assimilate them. But just like in the book they kept sticking around like the totem pole in the corner of the room and like the dust eventually settled.
