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.

Electrophysics knowledge notes
electricity
strong electricity
Weak current
PS: The discovery of electricity enabled mankind to Evolved from a powerful man who discovered fire to a ruler
atom
proton
Electronics -
neutron
formation of electricity
PS: Because the dissociation of atoms generates electricity
Positive electrode (missing electrons) Negative pole (extra electrons)
Conduct: generate current
The charge difference between the positive and negative poles (also called voltage difference: voltage) The size of the voltage difference is the size of the voltage
Case: Lightning, spark, arc, flame: plasma state The voltage that the human body can withstand is less than 60V
Applications of electricity
load
convert electrical energy into
Thermal energy: Resistance: Increases frictional heating of electrons Example: kettle, hair dryer, electric blanket, etc.
Kinetic energy: motor
Light energy: stimulates fluorescent materials to glow Example: lamp
Electricity use
When the negative electrode discharges from poor to flat, the electricity is used up. On the contrary, it is charging
Note: The positive and negative poles cannot be connected directly, otherwise it will cause a short circuit and explosion. The voltage is adjusted to correspond to the load
Battery
Hydrogen battery
lithium battery
ternary lithium
3.7V
Lithium Iron Phosphate
3.2V
Lithium titanate
2.8V
sodium battery
The dissociation of a proton in an element creates electricity
Series connection: V is added, AH remains unchanged Parallel connection: V remains unchanged, AH is added
