I always thought it was a western discovery. I learned about Cai Lun in Chinese school back in the day, it is neat that they boiled plants to make affordable paper! I love how the paper-making technology improved and spread to Korea and Japan! Because I can't imagine writing on animal bones or bamboo would be efficient at all...how would they even store all that?]]> 2017-02-17 13:11:48 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/154570243 https://padlet.com/gaoy3/qqa8jw5dw19c/wish/154756277 I always thought Egypt invented paper out of Papyrus plant stems but I guess I was wrong. When accidentally invented gun powder, do they really wanted to make immortality pills because that sounds a little crazy. Speaking of gunpowder as the most important invention, Disney did try to show the use of those dragon shaped gunpowder missiles in Mulan. ]]> 2017-02-18 18:57:07 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/154756277 https://padlet.com/gaoy3/qqa8jw5dw19c/wish/154820904 I had no idea that the Chinese invented the four most used objects around the world. the gunpowder, compass, technique of printing and paper-making. I find it amusing at times to learn about another cultures invention because 9 times out of 10 our own culture gives the impression that Americans were the first to invent everything. but however this is not true, theirs lots of other countries that have already came up with a solution to a problem that Americans are yet still trying to solve.]]> 2017-02-19 20:23:44 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/154820904 https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155012326 The abacus is a genius invention and i never knew it came from ancient Chinese culture. There are so many inventions i would not guess were from China, no wonder they are a leading world power. The Chinese are extremely inventive and we have obviously learned a lot from them. I like how they have named a crater after one of their world famous scientists- Zu Chongzhi. He helped advance the understanding of the value of pi . ]]> 2017-02-20 20:48:26 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155012326 immh2 https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155062107 I never knew China invented so much. I knew the compass and papermaking was made by China but I did not know that it was invented early (475 BC-221 BC, 206 BC - 25 AD). Also I heard so much thing about Abacus calculation. I knew what it was about but I never knew how it was calculated. After reading, it became a little clear with calculation. Also I saw on one of the Korean show that little kid uses Abacus and he was the fastest solving problem for calculating addition, subtraction, multiplication, and division! And because of that, that's how I knew about Abacus. ]]> 2017-02-21 05:36:21 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155062107 hendersonjl https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155070346 This is by far the most interesting Chapter to me. I had no clue that China was the inventor of gun powder, the wheel-borrow, paper and Kites. Hands down to China for the creator of paper, talk about a global affect! Is there a museum in China that provides a visual overview of this historic accomplishment? ]]> 2017-02-21 07:16:06 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155070346 https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155226312 This was a very interesting section to read because of the already existing interest that I had.  The section about gunpowder was one of my favorites. They created it by accident when they were attempting to create immortality pills. It's always interesting to see how the rise of technology and science is similar and different in different cultures.

For example, I already knew they invented gunpowder and paper. However, I was not aware that they invented so much more. I found it funny to find Spaghetti on the listed just because I thought that it was a Italian dish. 
I realized that Chinese still use a lot of natural herbs today. One time, my grandma took me to a Chinese doctor in New York. When we went to pick up the medicine, it was all herbs. The whole store was filled with herbs and the herbal smell. My grandma had to boil the herbs and I had to drink it. It was bitter.

I found it fascinating that the gunpowder was discovered by the Taoist alchemists when they tried to make pills of immortality. Most people who discover new inventions are always caused by an accident, therefore; it was interesting that this was also caused by an accident. ]]> 2017-02-21 18:59:35 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155264961 https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155305390 I had a vague knowledge of what was invented by the Chinese, but it was interesting to read on the four specific inventions; the compass, papermarking, printing, and gunpowder. I'm fascinated by the ingredients used to make paper, especially in its early stages of creation. I find it fascinating that the Chinese was also creative in how they could determine time by using a Copper Kettle Clepsydra.

I did not know there were so many inventions from Ancient China. I would love to see the celestial book, and how the ancient observations of space differ from modern observations of space. The abacus was also very interesting to me. I knew that it was invented in China, but it is great to know the history behind it.

I thought it was really interesting how they used different types of plants fibers, barks, rags and fishing nets as raw materials and steamed and cooked all to make paper; it most has been really hard without any technology. Also, I did not know about Zu Chongzhi mathematician. It interesting how much we use Pi in our math equations but I never thought about who came up with that number.  ]]> 2017-02-21 22:03:40 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155313811 daiy2 https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155317326 I have learned a lot of the history of how gun powder and printmaking techs form from a young age. It was really cool and I admired a lot about the wisdom of old people. But like other critic people said, other countries used the gun powder to open up their world, but at the same time China used gun powder to make firework. This was so sarcastic but realistic somehow. It made me felt sad a bit. But all the stories of these old technologies were so fascinating and made our life today so much more convinient.]]> 2017-02-21 22:24:11 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155317326 https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155317711 I learned a lot of things from this chapter I had not previously learned. I did not know that the Chinese invented the compass or gunpowder. I also had no idea about all that was done with papermaking. I also found the Gan & Shi's Celestial book to be very interesting. Overall I learned a lot from this chapter and enjoyed learning about all the inventions that we owe to China.]]> 2017-02-21 22:26:42 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155317711 https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155318309 This was by far my favorite chapter. I had no idea China was the inventor of such things that really had a global impact and are still super important today.]]> 2017-02-21 22:30:41 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155318309 https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155321341 This chapter did really amaze me. It's so interesting that way back in the past Chinese people could invent so many technologies to help them go through out their life. Not only they invented those technological techniques for the basis of life but also they invented that as a form of art. These kinds of art are truly amazing in my opinion. My question is: How does the government manage to maintain these ancient technologies? Do they have a place to demonstrate to people how to make ink, or gun powder, or something like that? Surely, technology is so much more advanced nowadays, these ancient technologies must be less and less noticed by people.]]> 2017-02-21 22:51:56 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155321341 https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155323894 Prior to reading this lesson, I did not realize that the Chinese invented all of these tools. I was just wondering if the development of these tools has ingrained them into ancient culture, (symbols, stories about using them, etc.)? I was also wondering, for the paper making technique, does anyone still practice these ancient Chinese skills like those? I was also wondering if it is common to have the "celestial book," in Chinese homes?]]> 2017-02-21 23:07:55 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155323894 https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155355027
Before reading this chapter, I was aware of China's inventions of gunpowder, paper, and printing. However, I did not know that Zhang Heng invented the first seismograph in the world and the first water-driven armillary sphere. I have not heard of the Celestial Book. It is said that 800 fixed stars were named. Did the Chinese names or English names come first for these stars? I am assuming that both sides of the world discovered and observed stars at the same time.]]> 2017-02-22 03:55:52 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155355027 guesmankb https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155602469 this chapter helped me to understand how the chinese government and science world come together. i really enjoyed learning about the different materials used to cook and how things were made like paper.  i already knew the basics behind fireworks but the brief history was interesting. i am a very tech-savvy person and love to be up to date on the new inventions. this was a really intriguing chapter and i even read ahead to the next...]]> 2017-02-22 20:57:06 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155602469 https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155909038 I had a general idea before reading this chapter that the Chinese invented the compass, abacus, and gunpowder. Little did I know that the Chinese invented paper and not the Egyptians. Also I had no idea that the first seismograph in the world was invented by Zhang Heng in 132 AD. I thought that the seismograph was a newer technology. It was also interesting reading about the Celestial Book and how scientists in later generations referenced the book. ]]> 2017-02-23 21:23:13 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155909038 https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155914386 In Western culture our education may lead us to believe that the Romans and Greeks were the true, original pioneers of medicine, writing, astronomy, and medicine but the reality is that the Chinese have had insight on these subjects for a much longer time. Some concepts are expressed differently, though different means but the results of Chinese ingenuity in undeniable. Inventions such as the abacus and of course gunpowder have shaped not only China but have redirected the course of history at large. I personally feel like we do focus a lot on Western culture, while important, versus the contributions of Eastern culture, in this case China.

I am also very grateful to Cai Lun for inventing a cheap form of paper to write on, I know that we are in the digital age but I prefer to read things on paper mostly. But it was a shock to hear that a Chinese man was the one who invented paper because I had also believed it was in Egypt. I also already knew about the compass and gunpowder were inventions of the chinese but I was surprised to find that they also perfected printing. ]]> 2017-02-23 22:22:00 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155918607 https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155920557 Before this chapter I had some general knowledge about Chinese technology, like how they invented things like fireworks, gunpowder, paper, the compass, etc. Though, what I found most interesting about this chapter was the section about astronomy. I wasn't aware of how astronomically advanced people were in ancient China and I thought it was interesting how so much information about the subject could be recorded back then and how some of the information was discovered without any technology, like how Gan De discovered the satellite of Jupiter with just his eyes.

It's hard to imagine life without such things as a compass and paper. I think it was very interesting to read about the people that came up with these objects. Their ingenuity is very inspiring for them to look at a problem and come up with a new solution that transformed the way people live. ]]> 2017-02-23 22:49:20 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/155922462 https://padlet.com/gaoy3/qqa8jw5dw19c/wish/156207461 It is very impressive how accurate people can get back in the time where everything is done by the human power. I can't imagining how many times they've tried in order get the inventions to work.

I never knew that Chinese people were the ones who invented compasses, paper, printing, gunpowder, etc. A lot of people mistake these inventions to be done by Arabic people. I never knew that they actually adopted these inventions from the Chinese. I think it is very admirable that they were able to come up with so many different inventions and pass them along to neighboring countries. This chapter was informative and a real eye opener to the Chinese culture. ]]> 2017-02-26 16:33:27 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/156254197 https://padlet.com/gaoy3/qqa8jw5dw19c/wish/156610712 This chapter was cool because it really put in perspective how many things the Chinese invented that all cultures STILL use today! The most interesting thing to me is how the Chinese discovered gun powder. I could have guessed a hundred different reasons how it was discovered, but I never would have guessed while making pills.]]> 2017-02-28 02:34:36 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/156610712 https://padlet.com/gaoy3/qqa8jw5dw19c/wish/156696771 The infulences China has made with their technology has been very important. The making of fireworks and abacus are just some of the ones that are still being used today. The abacus is like a calulator instead of buttons it has beads on rods. The top part is worth 5 and the bottom part are ones. I wonder how big the abacus could be when they had to count much larger numbers. ]]> 2017-02-28 13:19:07 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/156696771 https://padlet.com/gaoy3/qqa8jw5dw19c/wish/156845567 China has made many amazing contributions to science. Without their inventions and ideas we would not be where we are today. Gunpowder is an amazing chemical, it is a shame it is used so much for war. The abacus is so interesting as well; the idea of a calculator was outside of the box. ]]> 2017-02-28 19:36:44 UTC https://padlet.com/gaoy3/qqa8jw5dw19c/wish/156845567
