Pi in the Sky: Counting, Thinking, and BeingJohn D. Barrow's Pi in the Sky is a profound and profoundly different exploration of the world of mathematics: where it comes from, what it is, and where it's going to take us if we follow it to the limit in our search for the ultimate meaning of the universe. Barrow begins by investigating whether math is a purely human invention inspired by our practical needs. Or is it something inherent in nature waiting to be discovered? In answering these
John D. Barrow's Pi in the Sky is a profound -- and profoundly different -- exploration of the world of mathematics: where it comes from, what it is, and where it's going to take us if we follow it to the limit in our search for the ultimate meaning of the universe. Barrow begins by investigating whether math is a purely human invention inspired by our practical needs. Or is it something inherent in nature waiting to be discovered? In answering these questions, Barrow provides a bridge between the usually irreconcilable worlds of mathematics and theology. Along the way, he treats us to a history of counting all over the world, from Egyptian hieroglyphics to logical friction, from number mysticism to Marxist mathematics. And he introduces us to a host of peculiar individuals who have thought some of the deepest and strangest thoughts that human minds have ever thought, from Lao-Tse to Robert Pirsig, Charles Darwin, and Umberto Eco. Barrow thus provides the historical framework and the intellectual tools necessary to an understanding of some of today's weightiest mathematical concepts.Binding Type: Paperback

Colloidal is good
I used this non greasy oil on my scalp and it is good for dry scalp,but i didn't like it on my pillow case. It's fragrance free until sleeping with it on my scalp

no substitute for Aveeno
Pros: There's no smell (yay--I don't get why folks say it smells like oatmeal; it doesn't, it just smells like it doesn't have perfume added), and it spreads well. BUT: it's too thin and doesn't last well enough. Had my first eczema flair in years while using this. I'm going back to Aveeno fragrance-free. At least I tried.

its ok
its ok, has a lot of chemicals in it, but not 2% of colloidal oatmeal which is recommended for an eczema lotion. i like this brand because its cruelty free but this is not great for eczema. i actually like that it is not thick, but it doesnt calm my dry itchy skin very much.

It’s a great all-round lotion, it does what it says it does.
It is one of the lightest moisturizers I’ve used, perfect for whole body. Though, naturally, using more makes it more moisturizing, and it does have a big pump. It spreads and absorbs well. It is not sticky, but silky. It calms itchy, irritated skin. It’s pH-balanced. It has very nice ingredients. It has a lot of nutrients skin needs. It is fragrance-free, though the aromatic alcohol preservatives impart a slight rose-almond odor. It’s a good price. It’s a nice bottle and pump. However, it would be nice if it were more reliably and widely available.
