Discussion Overview
The discussion revolves around finding exercises and problems related to the Friedmann equation in cosmology. Participants are seeking resources that include calculations involving redshift, H0, scale factor, temperature, and horizons, particularly those that provide exercises with solutions.
Discussion Character
- Homework-related
- Exploratory
Main Points Raised
- One participant, Jacopo, is looking for websites or professors' homepages that offer exercises related to the Friedmann equation.
- Another participant suggests Wikipedia as a good resource for understanding the Friedmann equations.
- A third participant provides a link to a different resource, noting that the original request was specifically for exercises rather than derivations.
- Jacopo acknowledges the difficulty in finding exercises with solutions, mentioning that their textbook primarily contains theory and only a few past exam exercises.
- One participant recommends the book by Liddle as a good starting point for cosmology, and mentions Steven Weinberg's textbook as potentially having many exercises.
- Jacopo expresses interest in finding more information about the recommended books online, particularly regarding their exercise sections.
Areas of Agreement / Disagreement
Participants generally agree on the difficulty of finding exercises with solutions related to the Friedmann equation, but there is no consensus on specific resources that meet the request.
Contextual Notes
Participants mention specific textbooks and online resources, but there is no indication of the completeness or reliability of these resources in providing exercises.
