Bryson Reading Chapter 5-6

Quote: "With the passage of time Kelvin would become more forthright in his assertions and less correct. He continually... were relatively, but inescapably, youthful."

Question: A little bit after this quote, it gave me the impression that Kelvin sort of in a way, gave up. Did he actually give up or did he just kind of made his studies short?

Comment: The quote I chose really stood out to me because it made a good point when it talked about the sun being able to burn for a few tens of millions of years continuously without exhausting its fuel is very interesting. I'm still a little puzzled on how is it possible that theres absolutely nothing in physics that could explain this. It got me to thinking that maybe since theres no oxygen, no oxygen, in space, maybe, just maybe, it fuels itself with the oxygen it has. Overall, this reading was really interesting because of how it explains what these people did to try and figure these things out and all the things they wrote down and kept record of it, and explains in depth in my opinion.
