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.

Size: 7 Fl Oz (Pack of 1), Style: SPF 30
This is our go-to sunscreen. It has an 2020 EWG (ewg.org) safety rating of 3 (where a 1 is safest but often difficult to find and often too expensive and a 10 is the worst safety rating). We love that is not too thin or thick, so it goes on easily, and it works into your skin without leaving you white or greasy, has a neutral pleasant smell, stays on well in the water (up to 80 minutes), and is accessible (has a decent price around $1 per ounce and is easy to find in many local grocery and drug stores). It is the one my kids grab out of the pile every time! And the only reason there is a pile is that I am trying to find a sunscreen rated 1 or 2 by EWG that has all of the properties of Coppertone SPORT 30. The search continues....

Doesn’t come of from sweat or water
Size: 7 Fl Oz (Pack of 2), Style: SPF 30
The only sunscreen I use. Doesn’t burn eyes, doesn’t come off in the water or from sweat. Wish it came in SPF 20.
