So count me in!

LOL

So awesome. Hahaha.


When we were in New York in June, I went to the Dark Matter exhibition (a planetarium style video show) which was wonderfully narrated by Neil deGT. That’s where I bought my copy of the book. I could listen to him for ever. The details go in one ear and straight back out the other but the process is very pleasurable. I honestly think the only thing I retained from the exhibition is that there’s a lot of something called dark matter, which explains some gravitational effects that would otherwise be weird but we don’t know what the stuff is. The End. But the pictures were pretty. And now I can maybe find out more using the book 😁

Hey Jason! Good to see you, and thanks ;). I am not sure NDT really grasps the words "in a hurry" . . .

I feel like the best book I read on a related topic was Quantum: A Guide for the Perplexed, and when I read the review I wrote ages ago for that book, I feel like I might end up writing a similar one here.
It's like:
We create math to explain the physical behaviors we observe 99% of the time.
1% of the time the behavior doesn't hold true.
We try to figure out new math that addresses the 1%.
We can't.

"the fabric of space/time"
Also, I don't understand the concept of space curving . . .

This story is always funny to me
In 1919, Ludwig Silberstei (the author of one of the early books on relativity), came up to him and said,' Professor Eddington, you must be one of three persons in the world who understands general relativity'. On Eddington demuring to this statement, Silberstein responded, 'Don't be modest Eddington'. And Eddington's reply was, 'On the contrary, I am trying to think who the third is.
So our minds cant 100% grasp 4 dimensions, but but instead of thinkong of space as flat, think of it as 3 dimensional that you can move around in. Lets say jello. It has height, width, breath, and you can be inside of it but its made of something like trampoline material. Put a bowling ball in the middle and it creates a curve and smalled objets fall towards it. The key is to add time for the 4th dimebsion. To do this, watch the video below. The answer is at the end but you need to watch the whole video.
I hope this helps.


I loved the story, and it definitely made me feel better. The bowling ball analogy does help me, but just sticking with the three dimensions for the moment, is the bowling ball an analogy for the gravitational force? Or mass? Or something else?
Will definitely make time for the you tube video.
I never thought of space as flat, but more like an ocean of emptyness . . .so three dimensional yet, but I don't understand how it can curve. What is in the displaces space that the curve creates? In your analogy, there's a bowling ball in the space that was formally occupied by jello. And the jello curves around the bowling ball. Other than planets, is our space curving around?

If you are interested in reading more about it, I highly recommend the author Brian Greene.
I have read The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory and The Fabric of the Cosmos: Space, Time and the Texture of Reality, but I have not yet read The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos.
I read these books when we were still on Shelfari, so I lost my reviews, but it is probably about time for me to read them again! I like to get them in paper copy and bust out a perfectly sharpened #2 pencil to take notes because I really have to THINK about what Greene is saying.
Which makes sense, because astrophysics really isn't a topic for lay people in a hurry....

If you are interested in reading more about it, I highly recommend the author Brian Greene.
I ha..."
Ha ha, I definitely think you are right! I like the idea of hurrying, but I am a person who needs a conceptual grasp. If I am reading something explanatory and that ends up with me having twenty new questions, I'm not sure that's really giving me a fundamental understanding. It's just letting me chat at cocktail parties . . .as if I know something. Which I don't.

There is the belief that our universe is curved also. Think round jello, you are inside the jello but you cant penetrate to the outisde. If you keep going stright through space and do not encouter a larger mass, you will eventually come back to where you begin.


Oh no, I’m listening to him and loving it. But no footnotes as far as I can tell.

I feel as if somehow I know much of what he's telling, but not sure how except from going to planetarium shows, reading all kinds of fiction and news articles. Maybe Carl Sagan and PBS has something to do with it.
But I do enjoy when he tosses in the day to day analogy or thought -- so far my favorite is the hot chocolate and whipped cream. Will never look at that combo the same again.
My plan is to keep reading on my commutes to/from work, at least. Probably will finish it early next week. Stay tuned.

Edited: Just checked. there are 319 holds for audiobook! Seriously, 319?! I'll just read the ebook which I still have about a week before it has to be returned.

I don't even like audiobooks, but something about this one did make me feel like it would be a winner in audio.
Just to reassure you (not that you need it), I felt that the subsequent chapters got better. For me, the first few were the weakest ones; the ones where it seemed like some more background knowledge was necessary to truly grasp them.

I'm thinking about just what it is that's eluding me...perhaps when I've finished I can put it into words for a discussion.
It is incredibly easy and fast to read. I'm only reading it on my commute to and from work, and in less than 2 days, I've read half the book. I'm also enjoying his style a lot.
One of the reasons I think I sense the audiobook might suit me for this is that while reading, I keep hearing in my head and seeing in my mind's eye various planetarium shows I've seen that cover some of the same material. And ones at Epcot, LOL.
Anyway, about to head home so will get another 25 or 30 pages read tonight before putting it aside until Monday. Or maybe I will have made so much progress I will push to finish on Sunday. We'll see.

I have mixed feelings about this -- looking forward to discussing a bit.

I was not wowed. I did not dislike it. It read quickly and easily and was a terrific commute read. Yet I have no burning desire to read more about the cosmos. I am not rushing down the street to the NYC Planetarium to watch the latest film and check the latest exhibits. And I absolutely have not been bitten by a desire to read any Sci-fi using astrophysics and the cosmos in its storytelling.
My eyes also glazed over from time to time, or I would just zone out, or struggle to grasp something. That sort of surprised me because I studied a lot of math and science in my youth, as it came very easily to me. It also bored me and that clearly has not changed.
Thus, it gets a mediocre rating from me. I do think it might have had a different impact as an audiobook, but as NYPL hold #319, I was not going to wait. As I read, I could hear it in my head, even visualize it. Perhaps I will hear Tyson present some time. Oh and I did really enjoy the chapter about the Periodic Table chemicals that owe their existance to astrophysics. That's just super cool.

I can't believe how many times some subject has come up lately that pulls in the knowledge gleaned from reading this book! Everything from the turquoise sky over NYC when something happened at the Astoria, Queens Con Ed site (electrical arc caused by aluminum burning hotter than the sun and the equipment that contains it failing) to asteroids hitting Uranus.
I may need to bump up my rating!


Definitely a book choosing superpower
