Description:
A compelling firsthand account of Keith Devlin's ten-year quest to tell Fibonacci's story In 2000, Keith Devlin set out to research the life and legacy of the medieval mathematician Leonardo of Pisa, popularly known as Fibonacci, whose book Liber abbaci has quite literally affected the lives of everyone alive today. Although he is most famous for the Fibonacci numbers--which, it so happens, he didn't invent--Fibonacci's greatest contribution was as an expositor of mathematical ideas at a level ordinary people could understand. In 1202, Liber abbaci--the "Book of Calculation"--introduced modern arithmetic to the Western world. Yet Fibonacci was long forgotten after his death, and it was not until the 1960s that his true achievements were finally recognized. Finding Fibonacci is Devlin's compelling firsthand account of his ten-year quest to tell Fibonacci's story. Devlin, a math expositor himself, kept a diary of the undertaking, which he draws on here to describe the project's highs and lows, its false starts and disappointments, the tragedies and unexpected turns, some hilarious episodes, and the occasional lucky breaks.
You will also meet the unique individuals Devlin encountered along the way, people who, each for their own reasons, became fascinated by Fibonacci, from the Yale professor who traced modern finance back to Fibonacci to the Italian historian who made the crucial archival discovery that brought together all the threads of Fibonacci's astonishing story. Fibonacci helped to revive the West as the cradle of science, technology, and commerce, yet he vanished from the pages of history. This is Devlin's search to find him.

Moisturizing, effective, pleasantly scented sunscreen
Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1), Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1)
This is the go-to sunscreen our whole family has been using for years. It feels moisturizing (but not greasy) and is easy to rub in to avoid any kind of chalky, white residue. The scent is subtle and pleasant, not the strong pronounced sunscreen smell that a lot of others have. Best of all, it is effective! The bottle received is different than the one pictured on Amazon, but we’re not buying it for the bottle, so that’s okay. :) Would recommend.

I hate sunscreens, but...
Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1)
I hate sunscreen in general--for it's texture and smell. But, being the palest family on Earth makes it a daily necessity. I was pleasantly surprised to actually like the smell of this product! It's a light fruity fragrance. It has a smooth texture like lotion and glided on my skin without being too thick or greasy and no white marks. A little goes a long way too! I could hardly believe I was putting on sunscreen and not regular body lotion. My kids had no issue with it either! They let me put this stuff on their little faces without complaint since it goes on so smoothly. Most importantly, this product did it's job and we were sunburn free. The tube is small--4 ounces--but I don't care because it's so worth having something that goes on easy and doesn't make us greasy and stinky. I bought several tubes--one for each member of the family.

It’s ok
Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1)
Doesn’t smell like anything, especially not fruit. Seems to work well- it’s what we use on our faces. I started using this all over on my daughter because their spray version is not good.

Overall this is a very good product
Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1)
I bought this because every sunblock I own eventually gets in my eyes and burns the living daylights out of them. I prefer to use something that isn't laden with chemicals, is cruelty free and reef safe so this looked like it would fit the bill and indeed, it does.
It is a true "no tears" formula which I very much appreciate. As with so many zinc based sunblocks there's still a slight "Kabuki mask" effect but it isn't as bad as some of the other zinc products. I wouldn't go so far as to say it's easy to spread because it doesn't have a lot of "slip", doesn't glide like the non-zinc products. You do have to work with it for awhile to get rid of the decidedly chalky consistency but once you get going it seems to be okay. I think somebody else mentioned using a moisturizer before you put it on which seems like good idea even though this is supposed to be moisturizing.
Would I purchase this again? I'm pretty sure I will because the "no tears" aspect of the product is important to me. I'll probably use it with a light carrier oil on my face first, let that oil sink in and then put this on top. I'll keep you posted on how that works out.
Thank you, Alba Botanica, for being cruelty free and reef safe!
