Lots of diagrams. Has a lot of loaded philosophical statements that were useful when writing a thesis. Helps to explain singularity, cosmic censorship, etc.

Full of facts and impeccable research and theory. Reading it is a bit daunting. The language is complex and not very engaging, but there is no question that the material is sound.

As much as I enjoyed the concepts that were meticulously laid out in this book; it hurt to read. The book required a lot from the reader to understand and keep up with the complex theories, unless of course you brought along your PHD in experimental physics and cosmology, which I did not.

Rows and flows of angel hair
And ice cream castles in the air
And feather canyons everywhere
I've looked at clouds that way

But now they only block the sun
They rain and snow on everyone
So many things I would have done
But clouds got in my way

I've looked at clouds from both sides now
From up and down, and still somehow
It's cloud illusions I recall
I really don't know clouds at all

Moons and Junes and Ferris wheels
The dizzy dancing way you feel
As every fairy tale comes real
I've looked at love that way

But now it's just another show
You leave 'em laughing when you go
And if you care, don't let them know
Don't give yourself away

I've looked at love from both sides now
From give and take, and still somehow
It's love's illusions I recall
I really don't know love at all

Tears and fears and feeling proud
To say "I love you" right out loud
Dreams and schemes and circus crowds
I've looked at life that way

But now old friends are acting strange
They shake their heads, they say I've changed
Well something's lost, but something's gained
In living every day

I've looked at life from both sides now
From win and lose and still somehow
It's life's illusions I recall
I really don't know life at all

I've looked at life from both sides now
From up and down and still somehow
It's life's illusions I recall
I really don't know life at all

Reading this, but it is slow going.

I am not sure how some read this book, but as an undergrad physics student, all I could read are the first couple of pages before the 1st equations.

Penrose just isn't as good at popular science as Hawking is alone.

I gave it a good college try, but was immediately swamped by the intense theoretical physics and deep mathematics involved. As a series of lectures between the two physicists as they voice disagreements about the nature of the universe, it was interesting to be a sort of fly on the wall, to see what these big brains talk about when the rest of us aren't around. On the other hand, they're discussing these things at their own level and not the level of a layman, so one might as well be a fly on the wall for the comprehension of the subject is concerned.

I gave up after failing to understand even the nature of the disagreement.

Too much advanced mathematics for me, but, it still all comes down to that stupid cat ~

Cualquier posibilidad de lectura comprensiva de este libro queda sujeta al dominio del lector de un sinnúmero de conceptos y teoremas de la física matemática. A priori pareciera un libro que cualquier persona puede leer y entender (como Breve historia del tiempo), pero una vez que se llega a la matematización de los fenómenos y los diagramas que usan para representarlos de manera gráfica, todo se vuelve mucho más confuso. De todos modos la lectura me ayudó a aclarar algunos conceptos básicos del origen y fin del universo y de la mecánica cuántica.

Love the writing, no idea how to get in touch apologies, but happy new year. I enjoyed yesterday's article on the Big Bang :)
