I finished Get Ready For +Geometry. It's already late evening, and I'm feeling tired. I found out +that Brilliant.org is a great complement to geometry classes because it +provides visualizations, and the interactive approach really helps with +understanding shapes. Especially when it comes to understanding where +formulas like the area of a circle or the volume of a cone come from. +Sal says the proof for the volume of a sphere requires Calculus, I am +definitely looking forward to mastering it in the future. + +Some volume formulas: + +V(triangular prism)=(1/2)bhl +V(cube)=s^3 +V(shpere)=(4/3)πr^3 +V(cone)=(1/3)hπr^2 + +I also learned another tip: on macOS, we can type the character π with +the shortcut option+p. + +--- + +Teach Yourself Programming in Ten Years —— Peter Norvig +https://norvig.com/21-days.html + +I really enjoy reading the article, and I deeply believe in deliberate +practice. Why are people—including myself—in such a hurry? I guess it's +because time feels limited. we can't afford to spend that long +accomplishing a goal. The journey seems interminable, which discourages +us, so we constantly need to feel productive. Because of that, +fearlessness—as mentioned at the end of the article—may be a much more +important characteristic than people realize. + +The other day, I came across a blogger named BoJone +(https://spaces.ac.cn) while surfing the Internet. Some of his posts +date back 17 years, to when he was still in junior high school. Reading +those old posts and seeing what he eventually became is deeply inspiring +to me, and perhaps the best example of deliberate practice. He has been +interested in science, mathematics, and cosmology since childhood. +Through his blog, I can clearly see the power of long-term growth. + +Another thing that came to mind is Teach Yourself Computer Sience +(teachyourselfcs.com) which I have been procrastinating on for a few +years. I should remind myself to stay patient and focus on the present +moment. Instead of thinking about how long everything will take, I +should simply enjoy the learning process. + +Back to the article, there are also many valuable ideas in it. If you +want to master something, you need to be genuinely interested in it. The +best kind of learning is learning by doing. I can't master programming +or mathematics just by reading books. Read great code and learn from +other programmers. Write maintainable code. Lead projects if you can and +inspire others if you can. + +--- + +中國控煙困局：1.4萬億人民幣如何綁架政府？ +https://theinitium.com/20241206-initium-audio-china-tobacco-monopoly/ + +This is an old episode republished by Initium Media. I guess it was +republished because a woman confronted a man smoking at a bus stop in +Shenzhen this spring. The report organizes the timeline and tells the +story of how smoking bans in China eventually failed. It's a shame to +see how much official influence from the government and the tobacco +industry shaped the outcome. + +From my personal experience, it's almost impossible to avoid second-hand +smoke in Guangzhou or Foshan. You encounter it everywhere: walking on +the street, waiting at traffic lights, in restrooms, in sports stadiums, +in parks, and even while dining at fancy restaurants.
