Only Truth Matters

1. 高手的心法

自控就是意志力，我们需要调动情感，来合理化决策

• 正念自控：识别感情，接受感情，研究感情，分离。站在第三方的视角看待自己的情感

模式意识：切换自己的模式，压力模式，放松模式。减压的方式：增加控制感

• 可控就好好控，不可控就放下

调控快乐：快乐不由强度决定，而是外界刺激强度的改变

• 多样性和间隔性
• 浅的东西用间隔，深的东西自带多样性

信息论：

• 让自己的信息量高，有更多的选择权，充满意外，不可预测
• 跟别人沟通就多说几遍，增加冗余度

提高学习成绩：

1. 思维方式

价值观是道德，是具体的。我们应该用科学的量化的数学的思维方式

不要先有结论再去找证据。

• 媒体不会客观中立而会选择特定的群体，读者喜欢耸人听闻的标题
• 逻辑推理能力可能是为了说服而不是追求真理
• 避免说服式文章，追求第一手资料

给理性人相同的输入，会有相同的输出

痛点比锦上添花更重要，损失厌恶。

• 做决策需要我们克服本能，考虑长远

概率论的智慧

• 很多事情就是有随机的成分，不用过度解读
• 肯定会有误差，要学会忽略误差内的波动
• 赌徒谬误：过去不平均，就以为未来会抹平
• 不要刻意去寻找规律，有些事很难被预测
• 小数定律：数据少，随机就变得不随机。数据少，什么都说明不了

因果：人喜欢找因果，不承认巧合

1. Intro

Why: understand the universe we live, our existence, nature of the cosmos

• How universe works
• Origin of everything
• Exploring possibilities of life

Major problem

• Dark matter, dark energy
• The scale of universe
• Complex data and interpretation

1.1. Phase 1: Foundation of Astronomy

1. Introduction to Astronomy
   • Content: Overview of astronomy, its history, and significance.
   • Purpose: To set the stage for what astronomy entails and its role in understanding the universe.
2. Understanding the Night Sky
   • Content: Basics of observing the sky, constellations, motions of celestial objects.
   • Purpose: Observational skills are crucial in astronomy. This forms the basis for all astronomical observations.
3. Solar System
   • Content: Detailed study of our solar system, including planets, moons, asteroids, and comets.
   • Purpose: Provides an understanding of celestial bodies closest to us, essential for grasping more complex concepts later.
4. Stellar Astronomy
   • Content: Life cycles of stars, nuclear fusion, star types and properties.
   • Purpose: Stars are fundamental units of the universe. Understanding them is key to grasping larger structures and processes.
5. Tools of Astronomy
   • Content: Telescopes, detectors, and observational techniques.
   • Purpose: Familiarizes learners with how astronomical data is collected and analyzed, crucial for understanding modern astronomy.

1.2. Phase 2: Intermediate Concepts

1. Galactic Astronomy
   • Content: Structure and dynamics of galaxies, including the Milky Way.
   • Purpose: Builds upon stellar astronomy to explore larger structures, helping to understand the universe’s organization.
2. Cosmology
   • Content: Large scale structure of the universe, Big Bang theory, expansion of the universe.
   • Purpose: Addresses the origin, evolution, and eventual fate of the universe, providing context for all astronomical phenomena.
3. Exoplanetary Science
   • Content: Study of planets outside our solar system, methods of detection.
   • Purpose: An emerging and rapidly evolving field, reflecting current research trends and broadening the understanding of planetary systems.

1.3. Phase 3: Advanced Topics

1. Wisdom Teeth Extraction

Pro:

• Prevent future problem, like decay, gum disease
• Easier oral hygiene: potentially reducing the risk of plaque buildup
• Avoid over-eruption, may lead to other dental issue such as bite misalignment
• Age consideration, younger patients tend to recover more quickly

Con:

• Surgical risk: risk as infection, bleeding, nerve damage
• Recovery time: allocate time for recovery
• Cost and time
• If ain’t broke

Timing:

• Immediately
• Scheduled convenience, right way to do
• Wait and see

Decision: Schedule an extraction once available. Nothing to worry about right now, everything is good, dentist said the overall teeth situation is good

1. Persimmon Turn Soft

Mainly two types:

• Astringent, high in tannin and need to become soft and ripe to be palatable
• Non-astringent: can be eaten while hard and crisp. Would eventually soften, but still firmer than the astringent varieties

1. Aviation System

Airways: Invisible path in the sky, pilots follow the predetermined routes

Departure:

1. At the gate
2. Taxis to the runway
3. Get clearance from air traffic control
4. Take off

Landing:

1. Follow a descent path
2. Get clearance to land
3. Lands
4. Taxis to its gate

Traffic rule:

• Right-of-way rules
  • General rules
    • Non powered > powered
    • Balloons > non-powered
    • Distress aircraft >
  • Converging: the right has the right-of-way
  • Overtaking: aircraft being overtaken has the right-of-way
  • Head-on: both alter to the right
  • Landing: lower altitude
• Altitude assignments to prevent collisions
• Speed limits
• Rules for navigating around bad weather

Communication: use radio to communicate with air traffic control and other aircraft

Navigation: use GPS and VORs (Very High Frequency Omnidirectional Range.)

1. Intro

Governance of a country or area

• The debate among individual or parties having or hoping to achieve

How to learn? The theories, systems, institutions, the impact

Goal: Achieve a well-organized, harmonious society where

• Resources are distributed fairly
• Citizens live freely and safely

By using

• Rules
• Laws
• Systems

1. City Light Color, Why Yellow

• Older installation use sodium vapor lamps, emit yellow orange light
• Visibility and comfort
• Transition to LED, origin cold, now can produce warmer hues

1.1. How Sodium Vapor Lamps Works

Components

• Bulb
  • Contain small amount sodium
• Inert gas (usually neon or argon)

How:

• Starting, the inert gas ionized, easier at lower temperature
• Heating sodium, vaporize the sodium
• Sodium ionization, emit light efficiently
