De nuevo tarde, llego a esta lista de resoluciones. Revisión de la lista de febrero:

- Escribir sobre Matemáticas [pendiente]
- Escribir sobre Física [pendiente]
- Escribir sobre Historia de las Matemáticas [pendiente]
- Escribir sobre Historia de la Ciencia [pendiente]
- Estudiar blues en guitarra [completo]

Lo interesante es que volví a las clases presenciales de blues en guitarra. Pero sigo con poco tiempo para pasar por escrito lo que leo de historia de la ciencia, de matemáticas y de física.

Las resoluciones del nuevo mes:

- Escribir sobre Matemáticas
- Escribir sobre Física
- Escribir sobre Historia de las Matemáticas
- Escribir sobre Historia de la Ciencia
- Estudiar blues en guitarra

Nos leemos!
