Nuclear Physics: Forces, Decay, and Energy Principles
Forces in the Nucleus
- Gravity: Force of attraction.
- Weak nuclear: Weak interaction.
- Strong nuclear: Strong interaction.
The strong force is attractive at very short distances and repulsive at slightly longer distances as a residual effect of holding together electrons and nucleons. Isotopes have the same number of protons but a different number of neutrons.
Half-Life Calculations
| Half-Life Formula | Finding Number of Half-Lives |
|---|---|
N = N0 x (1/2)n | n = T / t1/2 
|
N = number of nuclei or mass remaining N0 = start |

Human actuality
La llamada machosfera se presenta como un espacio de defensa masculina, pero en realidad suele ser un refugio de resentimiento y simplificación. Bajo discursos de “verdades incómodas”, se promueven ideas que reducen las relaciones humanas a competencia, desconfianza y dominio. Esto no solo perjudica a las mujeres, sino también a los propios hombres, al encasillarlos en modelos rígidos de masculinidad que limitan su desarrollo emocional.
En lugar de fomentar el diálogo o la igualdad, muchos

Partial Differential Equations (PDE)
A Partial Differential Equation (PDE) involves a function u(x, y, …) and its partial derivatives.
- Homogeneous: If every term in the equation contains the dependent variable u or its derivatives. The general solution is simply the Complementary Function (C.F.).
- Non-Homogeneous: If there is a term that is a function of the independent variables only (f(x, y)). The solution is u = C.F. + P.I. (Particular Integral). Example: ∇2u = f(x, y) (Poisson’s Equation).
