Edited at 2024-02-11 16:17:21One Hundred Years of Solitude is the masterpiece of Gabriel Garcia Marquez. Reading this book begins with making sense of the characters' relationships, which are centered on the Buendía family and tells the story of the family's prosperity and decline, internal relationships and political struggles, self-mixing and rebirth over the course of a hundred years.

Project management is the process of applying specialized knowledge, skills, tools, and methods to project activities so that the project can achieve or exceed the set needs and expectations within the constraints of limited resources. This diagram provides a comprehensive overview of the 8 components of the project management process and can be used as a generic template for direct application.

From particles to universe
molecular
definition
The smallest particle that can maintain the chemical properties of a substance unchanged
Features
Matter is composed of a large number of molecules
There are gaps between molecules
There is a force of attraction between molecules
There is repulsion between molecules
There are interactions between molecules
molecular kinetic theory
diffusion
When different substances come into contact with each other, they will enter each other.
The movement of molecules in a substance is related to temperature. The higher the temperature, the more violent the irregular movement of molecules.
thermal motion
The random movement of large numbers of molecules
universe
"Geocentric theory" - Ptolemy
"Heliocentric Theory" - Copernicus
cosmic speed
First cosmic velocity
v=7.9km/s
second cosmic speed
7.9k/s<v<11.2km/s
third cosmic speed
v≥16.7km/s
atom
Model
"Jujube Cake Model" - Thomson
