Electromagnetism and Engines
Coulomb’s Law
Electric charge is the property of matter responsible for electromagnetic phenomena. Properties:
- Interaction can be positive or negative.
- The total charge of a set of particles is the sum with the sign of their individual charges.
- The total electric charge of an isolated system is conserved.
- Charge is quantized: it comes in discrete amounts that are multiples of an elementary amount.
The unit of charge in the SI is the Coulomb (C). Coulomb’s law describes the interaction between electric

ATOMIC PARAMETERS
Atomic Number and Mass Number
Each atom is defined by two features: its atomic number and mass number.
- The atomic number indicates the number of protons in the nucleus and determines the element in question. It is represented by the letter Z.
- The mass number is the number of nucleons (neutrons and protons) that make up the nucleus and determines the isotope of the element. It is represented by the letter A.
Isotope notation includes the mass number (A), atomic number (Z), and the element

Energy
Energy is the capacity of a body to interact with other bodies. Energy is neither created nor destroyed, only transformed. It is measured in Joules (J).
Types of Energy
- Kinetic Energy: The energy a body possesses due to its motion. Ec = 0.5 * m * v2
- Potential Energy: The energy a body possesses due to its position.
- Gravitational Potential Energy: Ep = m * g * h (g = 9.8 m/s2)
- Elastic Potential Energy: Ep = 0.5 * k * x2 (k = N/m)
- Mechanical Energy: The sum of kinetic and potential energy.
- Heat: The
Modernist Poets: Ezra Pound and T.S. Eliot
Ezra Pound
Early Work
Pound’s first important book was Cathay (1915), featuring translations like Sonnets and Ballads of Guido Cavalcanti. Cathay consisted of free translations/reinterpretations of ancient Chinese poetry, including “The River-Merchant’s Wife” and “In a Station of the Metro.” Some of these poems are imagistic, using hard images and striking juxtapositions, yet they also frequently employ narration, contrary to some of Pound’s own principles. While sometimes criticized for his liberties

Literary Topics
Carpe Diem (seize the day) encourages maximizing the present. Collige virgo rosas (gather ye rosebuds while ye may) relates to seizing the benefits of youth. Tempus fugit (time flies): emphasizes the brevity of life. Ubi sunt (where are they?): rhetorically questions the passage of time and the loss of those we knew. Beatus ille (the happy one): describes the happiness found in escaping worldly concerns. Locus amoenus (pleasant place): idealizes a harmonious natural setting. Memento
