In this week we talk about how those technology interrupts with our daily life. With the development of society, the technology changed our lifestyle. The technology covered almost everywhere, no matter you are the student, businessman, teacher, workers we all need to use the electronic devices. And people just text through their phone in everywhere, they will play with their phone on the subway, classroom, office and waiting for the food or even at the date.  People feel nervous when they lost their phone.  We acknowledge that cell-phone provide the great convenient to our life, but the problem is that when we meet our friend in reality, we are afraid to talk with each other. We are try to avoid the eye-contact with each other, because the technology make us become a robot.

Besides, l earned that how does internet hijack us in what ways,

First, people need to get the social approval from the internet, why does people like to spent time on internet even though they know they will addict with that? The reason is that others are also in the internet, people need to keep in touch with each other through the internet in order to get the social approval. For example, people like to leave the comment about what their friend are posting, in doing this in order to shows they have the good relationship with that friend and they also want more friend to join their conversation.   This theory also works on the Instagram,   the more ‘ like ‘ they get, the more social approval they have.

Also, people need to get the social reciprocity from the internet. There is the basic rules, like when your friend follow you should follow it back. Most of people like to ‘give the like’ to every picture, the reason they do that is because they want to ‘like it back’ when they post their own picture. It also works on the Facebook comment, when they leave a message on what their friend posting, they want get the reply back, otherwise they will feel uncomfortable with that. Thus we are living in the internet atmosphere. We will feel anxiety when there is no internet.

Artificial intelligence, is also we are so called Ai. Simplify speaking artificial intelligence is a intelligence system that are able to think like a human or even better than human. About the artificial intelligence, we are relate to the last 50 century, the father of computer Alan Turing come up with the idea  in order t Jude fi the computer is an intelligence way called ‘’ Turing  test’. The test is very easy, it works like this, let a computer to answer a series question in 5 minues,  if 30% answer let other believe this is what human did , the computer will pass the test. ,, 1995 Richard, Wallace create the chatting robot called ‘A. L.I.C.E, the normal conversation was added in the system, it include the thousands of data points and this is the model of the artificial intelligence.

Two years later in 1997 ,  the computer Deep blue , they use the artificial intelligence in the chess game to beat the world chess champion Garry Kaparou , this is also become a landmark events in the history of artificial intelligence research, this si also the first time than people start to afraid of artificial intelligence.

In 2000 Japan create e a robot ‘ASIMO’, he cannot only climb up and down the stairs but also can play the soccer and pour tea into the bottle, and it worked very flexible. , it can shows the functions that are similar with human, and have normal intelligence level.

In 2006, the concept of deep learning is a another major breakthrough in the field of AI technology , by establishing and simulating neural networks of human  brains  , the  mechanism of human brain is simulate to interpret data such as  images, sounds and texts. Thus, people saw the hope that AI is going to replace the human mind and decide to participate the business aspect.

In 2016 with the Deep mind’s game of AI Alpha Go, AI Alpha Go defeated LI shsihsi and ke jie,  people start to pay high attention to the AI technology

In 2017 the upgraded Alpha go Zero beat the Alpha go by 100 -0 record, using only three days of self- study , it takes at least 15-2- years of learning to be a top player compared to human chess players, their growing process is unbelievable.


The article also mention about the difference about AI and ML , artificial learning is a broader concept of machines being able to carry out tasks in a way that we would consider ‘ smart’..  Machine Learning is current application of AI based around the idea that we are able to give machines access to data and let them to learn for themselves.

From my perspective, I think AI is a very smart technology and AI include the technology that they can learn by themselves. But that doesn’t mean AI is able to replace everything. This include the perspective, like about the different news different things, different people have different thoughts.  They can only copy the thoughts, but the news thought is create by our humans. And I think the application of AI technology should not focus on how to beat human, instead we should focus on how to benefit for human, how should use AI to make human have better life is what should AI focus on .

   Is Technology making our education better? BLOG POST 2


Is Technology making our education better?

Last week, we read a lot of article about how dose technology affects our education and lifestyle. With the advance of technology, our teaching methods made a giant change. From the blackboard to electronic screen, from pencil to I-clicker, from notebook to iPad, Electronic devices and Internet become necessaries in our life. Millennial make friends on the Internet, when they hand out they rather than talking through the phone instead of having the real conversation.  What are the advantages and disadvantage?  My analysis is following.

Technology makes our learning method become more convenient. For example, we can see the world through browsing the picture.  If we want search specific information we just need to Google it. A lot of online book provide Hugh mount of books for us to read. Or if you miss a lecture, you can fins the similar material on the Internet. This is the age that tends to be an excess of information.  You never need to worry about lack of information but need you to worry about is how to select the appropriate information in the sea of data.

However, we also met some problems. Teacher and student cannot without the technology and Internet.  Like the Penn state university use Canvas, if one day Canvas was attack by the black hack, all of the database will lost and all of the homework will miss that is big trouble.

Also, according to the article on washing ton post, it said about 60 percent said it hindered students’ ability to write and communicate face to face, and almost half said it hurt critical thinking and their ability to do homework. Also, 76 percent of teachers believed students are being conditioned by the internet to find quick answers, leading to a loss of concentration.

Third, technologies lower our ability to have a deeply thinking. Nowadays, people just browsing information through the basic news, TV channel, Facebook. But are those news are real?  Too many superficial materials makes us lower our critically thinking skill. In the past, people willing to spend three or four hours to read a book, but nowadays, what people search on the internet is how to read a book in 20 minutes. Yes, I acknowledge that 20 minus are able to make a summary of the book. But what is the meaning of that. I think reading a book should have our own thoughts. One book has thousands of perspective

To Sum Up, the change of technology can provide us have a large platform to make a better research, but the material won’t change. People still need to learn and study and we should have patient to deeply judgment.

Millennial usually refer to the group of people who was born in 1994 or after that Most of millennial have the a lot of common characteristics, they are unfocused, and self–esteem.

There is a common phenomenon that in the society that most millennial addict with the social media.  The reason that they become like that have plenty . first reason is that Each parents will told their child that you are the special individual and nobody can replace you, most of student went to the honor class is not because they deserve but their parents want they to do that .

Second, Engagement of social media release a chemical material called dopamine, that is why when you get a “like you” feel happy, and you feel good when you received the response. Most people tend to compare their self with other through Facebook, Instagram and twitter and snapchat, through Facebook and Instagram seem to be the chosen platforms for seeing how they line up. According to this behavior, the social comparison theory amplify .people will post their best picture on the Instagram or Facebook, even though they are not that good.

Addict in social media impact our relationship, You got dopamine release which is the same chemical that makes you feel good when you drink we know that you get a dopamine release when you phone goes buzz or deep, you will get when you get the social media alerts.

Third, too much focus on the phone will make people have less conversation in the reality.  If the kids lost their way and cannot open google map because their phone was power off, they prefer to find a phone charger rather than asking people around, because they are afraid to talk to people

Thus, internet and iPhone become the big part of life, they can without new clothes, new shoes, or do not play games but they cannot without their phone. I remember when I was high school student, I have a sister from my homestay family, and she can play with her phone for 10-12 hours a day. And she will give the like to every Instagram picture, the purpose she do that is in order to the like back, but she do not real hang out with her friends and make friend in reality, she have a lot of friend on social media such as Facebook, twitter, or in stag ram. But when she met those people in reality ,  they just say hi to each other and said’ you know what I just give you a big like about the picture that you post ‘ and then they ended the conversation, what I saw about those behavior is really boring and I think she is living in . What she doing every day is that she is playing with her phone by herself in a gloomy room and do not want to talk with anyone.

I acknowledge that the social media brings the great convenient to our life, but I think there are too many people addict with phone and internet in the reality, which is horrible. Millennial should put the phone away and look at this world.

Brian McDonald Lecture.
From this lecture, I learned that the prevalence of obesity is the same in the rest of the world as the US. Globally people are making the same mistake. It’s easier to get access to starch foods than healthier. Cooking knowledge has denied. People don’t cook.
There are severa goals that lead to helping the problem. And they are all interconnected. People aren’t educated and it’s hard to learn if your hungry. And it’s important to understand why.
Sustainable ways to solve the issue with food. We have energy systems but a significant problem we have is our expenditure of energy when making and producing food. A challenge is how to create food without wasting more land.
The rise in flooding and storms are a threat to food storage system. New York food storage areas are in flood zones and there are not many places to store food in the city.
We live in a food network. It was developed to help determine where there might be certain food shortages but it didn’t get made.
Food systems have their issues. For example people care about how their food is produced and where it comes from and this makes things more complex and complicated.
There are many ways to change people’s diets such as cooking shows and books encouraging people to use products in their area.
I also learned that food waste is a contributor to the green house effect. This lecture put into perspective how our food is in a really fragile state and how the way we handle it really matters when going forward.

California’s New Strategy on Glass Recycling

CalRecycle just awarded a $3 million grant to Sioneer Stockton, LLC, a company working to build a glass processing facility in Stockton, California. Sioneer would use the grant to build a facility that is capable of precessing about 6,000 tons of glass per month. They will turn these post-consumer glass into a specialty sand called pozzolans. Pozzolans is a type of material that can be made into high-strength concrete that is used in infrastructure projects.

Sioneer Stockton got this grant from a competitive grant program called the “Recycled Fiber, Plastic, and Glass Grant Program.” The purpose of this competitive program is to lower overall greenhouse gas emissions by establishing new recycle facilities in California.

This program is a part of the “California Climate Investments.” It is a program that invests billions of dollars every year to work on reducing greenhouse effects. It also successfully creates a financial incentive for companies to invest in clean technologies and develop innovative strategies to reduce pollution and help with climate change. Their main projects includes affordable housing, renewable energy, public transportation, zero emission vehicles, environmental restoration, sustainable agriculture, general recycling and much more. At least 35% of these investments are made in disadvantaged and low-income communities.

I had no idea you can actually turn glass into sand. After a little more research on this topic, I found out that this is actually a pretty common recycling strategy around the globe. According to, New Zealand is using this practice to save their beaches. DB Breweries came up with a slogan, “drink beer, save the environment.” That is the best thing I have ever heard. They invented these machines that are able to crush empty glass bottles into a sand substitute, and use this substitute to fill the beaches. These machines look just like vending machines. You just need to push the container through a bottle-shaped hole, then the machine’s vacuum system will automatically remove silica dust and plastic labels, and each bottle will be crushed and turned into 200 grams of sand substitute. The whole process takes about five seconds.

Not just saving beaches, this sand will also be distributed for road projects, residential construction, even gold bunkers.

You see, recycling is not as expensive and inefficient as you think. You will need an investment to develop the technology, that’s for sure. But the results are definitely worthwhile. We can turn glass into sand in five seconds now. What’s next? We can turn plastic back to oil, probably. All we need is patience, and determination.

Write and Respond #2

At the beginning of the semester, I believed in climate change but was not fully aware of how serious it is or the ways people are trying to prevent it from getting worse. Between the lessons taught in class and speakers’ presentations throughout the semester, I realized that climate change is a very real thing and how imperative it is to take it seriously. Learning about what contributes to the climate change in our world was something I found interesting. I thought that greenhouse gases only meant carbon dioxide but learning that there were other gases such as water vapor, which contributes to 70% of greenhouse emissions, and methane, which contributes to 5%, on top of carbon dioxide was eye opening. Water vapor surpasses carbon dioxide in how much it contributes to the total of greenhouse emissions. Carbon dioxide is only 20% of the problem and is a direct human effect. Usually when I would hear about greenhouse gases, I assumed that it was all from car emissions and that was the main issue. Excessive carbon dioxide in our atmosphere is our fault as humans. Some does come from car emissions but, the amount of carbon dioxide has effects on all other greenhouse emissions making it an important cause of the climate change we are seeing.

Learning about fossil fuels and their effects on climate change was also something I was not aware of. Fossil fuels contribute to methane and carbon dioxide emissions. In class and through some readings, I learned about the ways people are changing our use of fossil fuels and trying to eliminate their harmful effects. In an article I read for an In the News post, a scientist has found a way to use solar panels and evaporating water as an alternative energy source.   This is just one of many ways people are attempting to cut down on fossils fuels by using renewable energy.  A few other forms of renewable energy already in use are solar power, wind, and hydroelectric plants.

Math 33 has made me more concerned for my generation and future generations to come. I realize that climate change is happening now and if steps aren’t taken to slow it down or change it, we will be the ones who have to live with the consequences. This past fall there was a crazy string of natural disasters that pose as a great example of the effects of climate change. We are the ones who need to educate ourselves and become more aware of what is happening around us. I still know people who do not believe in climate change or that climate change is not an important issue. They think it is only a phase or a natural change in climate and not something induced by man. After taking this class, I feel more of an obligation to correct people of their views on climate change and share what I have learned. This class has definitely changed my perspective on issues of sustainability and climate change for the better. It has also given me more respect for those who are working to fix this problem.

The amount of material and information I was unfamiliar with that we covered in Math 33 throughout the course of the semester far exceeded my expectations. Many of the lectures and guest speakers were eye-opening to me in the sense that they introduced many important concepts that I thought I knew more about than I actually did, and certainly concepts that I should pay more attention to in the future. The recycling unit was one which probably stood out to me the most, largely because it’s such an important and common aspect of everyone’s day to day lives and plays an enormous role within societies around the world. This unit also made me realize how little I actually know about recycling, which is something that I’ve actively participated in without consciously thinking about the effects and implications that it has both economically and environmentally. I learned several things in each of the sources that were provided pertaining to recycling, and many of the statistics and lessons will certainly be in the back of my mind as recycling continues to play a role in my life. I was impressed to learn that recycling efforts have increased dramatically over the past several decades and have become far more efficient as well, with the recycle rate in the United States being roughly 32%, up from 9% in 1980 ( European countries have also making incredible advances, with recycling rates soaring in many places across the continent. It’s also important to know some of the positive benefits from efficiently recycling, including but not limited to conserving natural resources and reducing the amount of waste that is placed into landfills, which have been proven to yield detrimental greenhouse gases. However, despite many of these positive points being made about recycling in The Economist, I found “The Reign of Recycling” by John Tierney to be incredibly intriguing as it challenged many of my previous understandings of many aspects of recycling. The article touched on several environmental aspects of recycling, however, I found his points regarding economic aspects to be more intriguing. Tierney states that although the practice of recycling has reached more people than ever before, there hasn’t been much positive change regarding its environmental and economic impacts. As a matter of fact, he states that because “prices for recyclable materials have plummeted because of lower prices and reduced demand for them overseas” (Tierney, NY Times). He goes on to contradict a point made in the article published in The Economist, saying that the national rate of recycling has stagnated in recent years, which comes as a cause for concern throughout the recycling industry. Another interesting point that Tierney brings attention to is the fact that as recycling continues to move past mostly paper and metals and into glass, food scraps, and assorted plastics, “the costs rise sharply while the environmental benefits decline and sometimes vanish” (Tierney, NY Times). Tierney concludes his insightful article by proposing several solutions to the problems facing recycling, specifically pertaining to what a socially conscious person should consider. He mentions the possibility of proposing a tax or sorts pertaining to the carbon content of garbage, bringing light to thorough research conducted by Dr. Kinnaman, an economist at Bucknell University. Tierney theorizes that there are several alternatives and initiatives that make more sense economically and environmentally than recycling practices that are currently embraced but the fact that recycling appeals to many voters and makes people feel good about themselves is one of the driving factors behind continuing flawed recycling efforts. I believe that there are important and valid statistics and arguments presented in both the article in The Economist and John Tierney’s “The Reign of Recycling.” I also believe that there is an important lesson to be learned from the contrasting opinions of both the authors; that it’s important to consult multiple articles and sources in order to obtain several points of views and decide your stance based on the most strongly supported facts and opinions. Not only did I learn a lot from several different lessons throughout the course of Math 33 this semester, but I also improved my analytical and comparative skills in seeking the best information, which is something that I will carry with me through the remainder of my studies and into my future beyond my undergraduate education.

I am not usually looking forward to a math class because math is really not something I’m good at. But this course is different. I learnt quite a lot from it. I thought I would be doing a lot of calculus and equation solving. But I actually learnt something that’s practical in real life.

I really like the project that we did about a month ago. We learnt about a variety of different energy saving methods. The topic I picked was about how much energy we can save by using stairs instead of elevators, and how much calories we can burn in the process. I also learnt about how regular stair climbing can help prevent all kinds of diseases like heart problems, joint pain and high blood pressure. And by reading other people’s blog posts, I learnt a lot outside of my own project. For example, unplugging your microwave and toaster can save enormous amount of energy. Line drying your clothes can save about 1/3 of your monthly electricity bill. Using LED bulb instead of a high-efficient incandescent bulb can also save a lot of energy. These are all something we can do on a daily basis. They don’t bring us any inconvenience at all. I used to think it wouldn’t make much of a difference through these small actions. But math proves that we can make a huge impact on our environment. I always know that climate change is a serious issue. We all know that through frequent droughts, hail, floods, etc. But I never had the discipline to actually do anything about it. It’s a good time for me to start caring and do something about it.

Sometimes what I learnt from this class challenges my beliefs. I remember the reading assignment about how recycling is completely useless and costs too much money. The best way to deal with our garbage is to bury them. I still don’t know how I feel about that. Land fills pollute groundwater and harm wildlife. Most importantly, majority of our garbage is being dumped to third world countries. We are not burying our garbage right under our feet. I don’t think that’s a responsible move, though I admit I’m not an expert in environmental science to decide what’s right or wrong. I still believe recycling is the way to go. Maybe the process is still quite expensive right now, that doesn’t mean we should just give it up as a whole. I remember I saw a youtube video last year about how we can turn plastic into oil. It was done by a group of Japanese scientists in their garage. If more companies adapt this method, we can make recycling more affordable. I believe there are more efficient and cheaper recycling methods out there. It’s just some companies refuse to adapt them because of switching cost.

I have to say I am more confident now about my ability to measure how human behavior affects global warming. I can now better track my daily routine and understand how my actions will result in a positive or negative impact on our environment.

Rob Nixon Talk

Haley Brown

Math 33 Extra Credit

On Friday, December 1st I saw Rob Nixon give a talk called Slow Violence and the Environmentalism of the Poor and it was extremely informative. Nixon started off his talk by talking about social movements that have been arising all over the world and how these movements all have connections to each other in one way or another. He says there are certain threads that run through each movement. The common grounds concern the word “disparity” and the edges of disparity have reached a tipping point. Citizens are rising up and saying that having a huge gap between the rich and the poor isn’t right. That the greater society should have a chance for a dignified future. He adds that the word decency really resonates with Midwestern values and insists that there is an indecent distribution to access for a dignified future.

Nixon then went into to talking about the slow violence and the environmentalism of the poor. He said that we as people are used to thinking of violence in terms of “immediate, explosive and spectacular”. Which basically means that violence erupts into instant and concentrated visibility. For example, when we think of violence we think of a fist fight or a murder, quick and easy to spot. He refers to “slow violence” as violence that isn’t instantaneous and not spectacular but instead is slow and builds attrition. So at first it is hard to notice the violence that is building until it is at it’s peak. Nixon also says that the repercussions of the violence happen slowly and over a long period of time.

Nixon then moves on to talk about how our environment is being extremely affected by our weather patterns and climate change is the sole reason for that. Nixon believes that us as humans, have to make changes quickly in order to save our islands and dying wild life.
