After several months – was it really back in January that I posted my most recent update in this series? – I picked up “The Elegant Universe” again and kept reading. On page 349 (in my edition), Green talks about how there was a moment where the universe from being opaque to being transparent.
He then goes on to describe the moment of the birth of the universe in terms that make me think about how he talks about black holes in the previous chapter (p 342-344?). I’m not a hundred percent sure why, but this part of the book reminded me a little of those four-axis graphs, with space on one axis and time on the other, and black holes sucking in all information. It brought to mind the image of a God’s Eye, or one of those cool graphic design things everybody used to doodle in high school (the nearest I can find via Google Images is the first graph used on this total stranger’s blog entry, but imagine four quadrants of that facing one another).

Have set up a paper.li for Climate Change, so if you want to see what Twitter is saying about that in advance of Hot Mess‘s March release, click here.
Read a fascinating paper last night called “Can language restructure cognition? The case for space,” which is about how different frames of reference carry through both verbal and non-verbal tasks. It’s not a long paper, and once you get through the initial terminology it’s very readable. Check it out if you have an interest in these things. It’s from 2004, so if there’s been more work in that area and anybody wants to pass on a link, that’d be great.
You’ll notice I haven’t posted any Homework Takeaways recently. This is not because I finished my homework. I still have about half of “The Elegant Universe” to go, plus the extra credit. The science got a little daunting but after last night’s success with the above I’m feeling ready to take on the world, so to speak, so I’ll probably get back to that shortly.

I’m entering the second half of Brian Greene’s The Elegant Universe, and last night read a beautiful, resonant section about Calabi-Yau dimensions. (That page is in French, though Google translate seems to be handling it OK; the image above is taken from that page’s reproduction of the image in the book.)
“If you sweep your hand in a large arc,” Green writes, “you are moving not only through the three extended dimensions, but also through these curled-up dimensions. Of course, because the curled-up dimensions are so small, as you move your hand you circumnavigate them an enormous number of times, repeatedly returning to your starting point.”

Another good point brought up in Brian Greene’s “The Elegant Universe.” After overturning Newtonian physics, Einstein ran into a situation that suggested the universe might be expanding. This was, according to Greene, too much for the genius to handle; he came up with some kind of way of negating the reality as he knew it.
Some years later, Edward Hubble was able to demonstrate that the universe was indeed expanding.
I’m reading Brian Greene’s “The Elegant Universe”. I decided to start organizing some of the thoughts I’m having as I read this book.
The most interesting line I read so far today was about the age of light. Greene is discussing how objects use up their motion either in time or in space, with most objects expending most of their energy via movement through time – that’s why nothing can achieve light speed, except for light.
Therefore, this means that light expends all its motion by moving through space, and the inverse meaning is that light doesn’t age.
As he puts it in his book, “Thus light does not get old; a photon that emerged from the big bang is the same age today as it was then. There is no passage of time at light speed.”
Kind of makes me want to go back and watch the end of SUNSHINE again.
