 Today I have learned how to do linear transformation and what's the meaning and propose of doing it. We can solve geometrical problems thorought linear transformation, like rotating a matrix and reflecting a matrix, and the area of graphic thorough linear transformation can be detA times than it's original one.Yeah very cool.  Today, I learned how to do linear transformations and understood their meaning and purpose. We can solve geometrical problems through linear transformations, such as rotating a matrix or reflecting a matrix. The area of a shape after a linear transformation can be det A times its original area. Yeah, very cool! 今天我學會了怎麼做線性轉換,也理解了它的意義和用途。 我們可以透過線性轉換來解決幾何上的問題,例如旋轉矩陣或反射矩陣。 一個圖形在經過線性轉換後,它的面積可以是原來的 det A 倍。

Today I was making a great progress in law of conservation of mechanical energy in the library. I did some exercises and finally understood questions I didn't before, espacialy questions related to springs, just use a sole equation and it can be sufficient for most of questions :1/2kR^2=1/2kx^2+1/2mv^2. Today, I made great progress on the law of conservation of mechanical energy in the library. I did some exercises and finally understood the questions I didn’t understand before, especially the ones related to springs. You can simply use one equation, which is sufficient for most of these questions: ½kR² = ½kx² + ½mv². 中文翻譯: 今天我在圖書館裡對「機械能守恆定律」有了很大的進步。 我做了一些練習題,終於弄懂了之前不會的題目,特別是和彈簧有關的題目。 其實只要用一個公式就可以解決大多數這類問題: ½kR² = ½kx² + ½mv²。

 It's good for me to finish 8 matrix questions in the library today, and I have also finished English assignments for tomorrow. I used to forget to do school assignments, espacially English, causing me felt embarracing when the teacher checks out our homework, hence, my general performance being deducted quiet often. In order to solve this problem, recently I have aranged these scool assignments into my daily basis, with tools like google calender's help, I could easily remember what things I had not do and what time I should do it. Forming a good habbit is good for various demensions, from academic performance to self-confidnece, so I better do more about it.     ✅ Corrected English Version: It was a good day for me—I finished eight matrix questions in the library and also completed my English assignments for tomorrow. I used to forget to do my schoolwork, especially English, which made me feel embarrassed when the teacher checked our homework. As a result, my ov...

Today, my group and I gave our Earth Science presentation. The topic was the floating city in the Netherlands and the carbon capture plant in Iceland. Our presentation didn’t go very well because one of my teammates took too much time at the beginning, which left me with too little time, so I had to end my part hastily. Another reason the presentation didn’t go smoothly was that we chose to present two existing green energy examples instead of coming up with a unique and original idea. Other groups that chose to create their own proposals had shorter presentations, which made things go more smoothly for them. This difference in approach was one of the main reasons why we had problems with our presentation. 我今天和組員進行地科報告,內容是荷蘭水上都市和冰島碳捕捉工廠,我們報告的不是很成功,因為我的組員在前面耗時太久,導致我時間不夠,只能倉促的結束,由於我們報告的方案是找現成的兩個綠能例子,而不是自創一個獨特的想法,其他組選擇第二個方案的報告時間都比較短,這是造成這次報告問題的主因。

 Today my chinese teacher have taught us some gossips about some famous ancient poets, the most interesting one to me is about yong liu, he was the most famous poet in his era, everyone could sing his song, and the contents about his poetry was all about his romantic love story with each city's girls, he roved in the country and dating with ladies, than he wrote their story into poets. My classmates were envy about his experience, and jelous to his good-looking face and lifstyle, I think he treated his lovers with sincere, and there must to be some reasons for him to make such a difficult choice to keep roving.  ✅ Corrected English Version: Today, my Chinese teacher told us some gossip about famous ancient poets.

 Today my chemistry teacher taught us some concepts related to catalyst, a myth about if catalyst join the reaction, the answer is yes, what's more, different catalyst can lead to different product in the same chemistry reaction. The priciple of catalyst is providing another route for the reaction process, the route need less energy to make the product, so more molecular can join the reaction, the more the molecular have joined, the more frequently they have collide to each other, so the rate of reaction ascent.  Corrected English Version: Today, my chemistry teacher taught us some concepts related to catalysts. There’s a common myth about whether a catalyst participates in a reaction—the answer is yes. What’s more, different catalysts can lead to different products from the same chemical reaction. The principle of a catalyst is that it provides an alternative reaction pathway that requires less energy. Because of the lower energy requirement, more molecules can participat...

 Today in physic class, my teacher had done the realm of the final exam, so he decided to teach the additional concept of solving the energy related question, which is internal kinetic energy. This new concept of energy emphasizes the two objects have relatively velocity, causing a relatively kinetic energy between the two objects. for instance there were two objects started with a relatively movement and subsequently they relatively still, their must have done some work to cause this resault, then we can erect an equation about W= delta Ki[internal kinetic energy]+Kc[central kinetic energy], through out this equation we can obtain the value of velocity . ✅ Corrected English Version: Today in physics class, my teacher had already covered all the material for the final exam, so he decided to teach an additional concept related to energy: internal kinetic energy . This new concept emphasizes that when two objects have relative velocity, there is kinetic energy associated with their ...
