This revisionist, completely accessible and radically inclusive history of mathematics is as entertaining as it is important
Mathematics shapes almost everything we do. But despite its reputation as the study of fundamental truths, the stories we have been told about it are wrong. In The Secret Lives of Numbers, historian Kate Kitagawa and journalist Timothy Revell introduce readers to the mathematical boundary-smashers who have been erased by history because of their race, gender or nationality.
From the brilliant Arabic scholars of the ninth-century House of Wisdom, and the pioneering African American mathematicians of the twentieth century, to the 'lady computers' around the world who revolutionised our knowledge of the night sky, we meet these fascinating trailblazers and see how they contributed to our global knowledge today.
This revisionist, completely accessible and radically inclusive history of mathematics is as entertaining as it is important.

Works great, could use a better sprayer
Style: Kids SPF 50, Size: 5 Fl Oz (Pack of 1)
I gave it 4 stars ONLY because I've had the nozzle break on at least 1 of these. So they could improve the way it sprays, but overall I'm very happy with the product. It keeps my whole family from getting burned and goes on clear. I love this because my kids always complain that they don't like the whitecast, so this one is a keeper!

Really nice sunscreen
Style: Kids SPF 50, Size: 5 Fl Oz (Pack of 1)
I always buy kids sunscreen because everything else burns my eyes. I haven't notices this stuff burning. It smells really nice and doesn't feel yucky going on like some stuff does.

DOESNT SPRAY do not buy
Style: Kids SPF 50, Size: 5 Fl Oz (Pack of 1)
Doesn’t work AT ALL. And I’m annoyed because it’s not eligible for return even with prime. What am I supposed to do with a sunscreen that won’t spray? YES, it’s in thru blocked position, it will not spray. I’d love my money back please.

Do NOT buy, it’s literal poison. Has forever chemicals.
Style: SPF 50 Spray Mineral Sunscreen, Size: 4.5 Ounce (1 Pack), Style: SPF 50 Spray Mineral Sunscreen, Size: 4.5 Ounce (1 Pack)
🚨do NOT buy this🚨It has forever chemicals in it - Tetrafluoropropene. Also has Hydrogenated polydecene - The chemical structure of synthetic hydrocarbons is similar to that of MOSH, another group of petrochemical-derived ingredients. A 2016 study states that "it seems prudent to assess their safety in the same way," suggesting that they could have comparable toxic effects on the body. MOSH may accumulate in the body, particularly in lymph nodes and body fat, where they could trigger inflammatory reactions. Liver effects have also been observed experimentally in certain types of rats, but have not been confirmed in humans to date. The European Food Safety Authority (EFSA) recommends continuing studies to better assess the toxicity of these MOSH compounds, as "the consequences of the long-term accumulation of MOSH on human health have not been evaluated and remain uncertain." These compounds should especially be avoided in products where there is a risk of ingestion, such as lip balms and lipsticks.
Moreover, the production of this ingredient has a significant environmental impact due to the extraction of hydrocarbons from underground and the high energy consumption required for its manufacture.
