When I first opened up the readings for today I had a mild panic attack and painful flashbacks to general physics, but surprisingly I actually kind of enjoyed these readings (much more than the calculus readings anyways!). The Thorne readings especially did a really great job of explaining Newton’s and Einstein’s theories and the relationship between the two- at least as good of a job as my Physics 211/212 classes did! One of the first things that really struck me was Einstein’s realization that his theory of relativity and tidal gravity were actually the same theories worded in different ways. I was always under the impression that the physicists of the world had stumbled along for centuries using Newton’s laws until Einstein came along and was able to prove that Newton was wrong. In reality however, scientists using Newton’s laws alone were able to make incredibly accurate predictions! According to Thorne, Einstein’s discovery did not prove that Newton was wrong, simply that he did not have “the whole picture.” I also found Einstein’s history and the process he went through over the years to develop his theory of relativity very interesting and amusing- especially his professors description of his as lazy. If only this was the kind of stuff we learned in gen. physics...
Another point that interested me was the distinction both authors made between physics and mathematics. Both articles stated several times that Einstein was a brilliant physicist but only an adequate mathematician at best. From my frame of reference (lol), physics and math are so similar that I cannot imagine someone being good at one but not the other. I always believed that to understand math was to understand physics and vice versa... Apparently Einstein is proof that I was wrong! Of course Einstein’s “bad at math” is not equivalent to my bad at math. If I was as good at math as Einstein was bad at it I could probably be a math major.
The final thing that really stood out to me was Greene’s claim in the third article that eventually all matter in our universe would be converted to energy. I of course knew that there was a relationship between mass and energy, and that mass can be converted into usable energy, but it has never crossed my mind to emphasize the equation the way Einstein himself did- with the emphasis on the creation of mass from energy rather than the other way around. To my knowledge, we have not yet been able to do this in a lab, but I am very ignorant about physics so someone please correct me if I am wrong! The ability to create mass from energy such as heat or light would be a truly amazing thing!
