Llegó la hora de escribir las resoluciones de febrero, algo tarde. Primero, un repaso de las de enero:

- 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]

Le he dedicado bastante tiempo estas semanas pasadas a leer sobre matemáticas, física y su historia: temas muy interesantes, que quisiera comentar. Pero no he tenido el tiempo de pasar en limpio por escrito en posts. Espero que pueda retomar esa actividad en las semanas que siguen.

Mis 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!
