When The Planiverse ?rst appeared 16 years ago, it caught more than a few readers off guard. The line between willing suspension of dis- lief and innocent acceptance, if it exists at all, is a thin one. There were those who wanted to believe, despite the tongue-in-cheek subtext, that we had made contact with a two-dimensional world called Arde, a di- shaped planet embedded in the skin of a vast, balloon-shaped space called the planiverse. It is tempting to imagine that those who believed, as well as those who suspended disbelief, did so because of a persuasive consistency in the cosmology and physics of this in?nitesimally thin universe, and x preface to the millennium edition in its bizarre but oddly workable organisms. This was not just your r- of-the-mill universe fashioned out of the whole cloth of wish-driven imagination. The planiverse is a weirder place than that precisely - cause so much of it was "worked out" by a virtual team of scientists and technologists. Reality, even the pseudoreality of such a place, is - variably stranger than anything we merely dream up.Binding Type: Paperback

No white cast.
Size: 3 Fl Oz (Pack of 1)
I would prefer a 100% mineral sunscreen that is this sheer, but at least it's a hybrid. It goes on smoothly, no white or blue cast, and protects well. Very happy with this product.

Generous amount and is a good sunscreen
Size: 3 Fl Oz (Pack of 1)
Goes on with a slightly white cast, but it’s cost effective. If they could only get rid of the white cast! Doesn’t pill under makeup, or over. can try mixing together with liquid foundation to eliminate white.

Yes!
Size: 3 Fl Oz (Pack of 1)
This was a suncreen reccomended to me by my dermentologist. I absoulutly love it! It sits well under my makeup! I usally do a soft glam everyday and I apply foundation 6 out of the 7 days of the week. It helps my skin look glowy too! It hydrating for my acne prone,dry, super sensitive skin. No white cast! And it doesn't smell. I've tried over 50 dollar sunscreens but this one is the best! I also live in Texas so sunscreen is a must and I live a active lifetsyle going to college everyday.

Go-To for Reef-Safe & Light-Weight Sunscreen
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
Favorite sunblock to travel with. Appreciate the simplicity of it, and the fact that it rolls on and rubs in smooth. Of course the iconic scent is also a plus.

Great choice
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
After I suffered a second-degree burn from steam, I was told by my doctor that I would have to keep my new fresh skin sun-blocked for up to a year to avoid any scarring or hyper pigmentation. This has been a great selection as it is a roll-on, Which helps a lot with preventing messes that can happen with traditional sunblock bottles. I also like that it is easy to travel with, and the fact that it is zinc based.
