"Witty, compelling, and just plain fun to read . . ." --Evelyn Lamb, Scientific American The Freakonomics of math--a math-world superstar unveils the hidden beauty and logic of the world and puts its power in our hands The math we learn in school can seem like a dull set of rules, laid down by the ancients and not to be questioned. In How Not to Be Wrong, Jordan Ellenberg shows us how terribly limiting this view is: Math isn't confined to abstract incidents that never occur in real life, but rather touches everything we do--the whole world is shot through with it. Math allows us to see the hidden structures underneath the messy and chaotic surface of our world. It's a science of not being wrong, hammered out by centuries of hard work and argument. Armed with the tools of mathematics, we can see through to the true meaning of information we take for granted: How early should you get to the airport? What does "public opinion" really represent? Why do tall parents have shorter children? Who really won Florida in 2000? And how likely are you, really, to develop cancer? How Not to Be Wrong presents the surprising revelations behind all of these questions and many more, using the mathematician's method of analyzing life and exposing the hard-won insights of the academic community to the layman--minus the jargon. Ellenberg chases mathematical threads through a vast range of time and space, from the everyday to the cosmic, encountering, among other things, baseball, Reaganomics, daring lottery schemes, Voltaire, the replicability crisis in psychology, Italian Renaissance painting, artificial languages, the development of non-Euclidean geometry, the coming obesity apocalypse, Antonin Scalia's views on crime and punishment, the psychology of slime molds, what Facebook can and can't figure out about you, and the existence of God. Ellenberg pulls from history as well as from the latest theoretical developments to provide those not trained in math with the knowledge they need. Math, as Ellenberg says, is "an atomic-powered prosthesis that you attach to your common sense, vastly multiplying its reach and strength." With the tools of mathematics in hand, you can understand the world in a deeper, more meaningful way. How Not to Be Wrong will show you how.Shipping Notes

Hair growth
I see results with my hair growth I'm very pleased. There is a noticeable smell to it but dissipates over a short time.

Great product, saved my hair
Honestly this is one of the best products I have ever used for my hair. I have been able to increase volume and thickness of my hair. The product is versatile and can be used in conjunction with other products as well. The application is very easy and I usually use any excess product on my skin for the added benefits. If you have fine hair your hair will get oily if you don't wash out so I just apply at night and wash out the next morning. Overall my hair is so much healthier and I am really happy I found this. Also I apply this 2-3 times per week overnight and wash in the AM. It will stain your pillow case so sleep with a bonnet or something with breathable material.

Love this batana oil over the other brands
This batana oil has natural ingredients and leaves my hair very moisturized. I have seen some hair growth after using this for a few weeks. So it's great value for my money. It does have a coffee scent but that doesn't bother me at all. I would definitely repurchase this again.

**UPDATE ON PDT*** Ingredients changed
Ok here’s my update (4/4/26)
We loved it. It did what it was supposed to do in the beginning but now I stopped using the product. Ingredients must’ve changed. It’s now a darker color, it doesn’t dissolve like it did in the past, and worst part— my daughter’s hair started breaking off. It could just be her hair but I don’t want to take chances. The ingredients definitely changed.
We are trying azure batana and will stick with it for 3 months to see results. But as of now their product looks like the real deal. It’s a shame because I like consistency. I’ll stick with one product for years. Oh well. Tossed this one out.
(Pic 1-2 AFTER USING; Pic 3 BEFORE USING)
Yes it works. It smells so if you’re sensitive to smells, you might only want to use it as a deep conditioner. Both my daughter & I are adjusted to the smell and love the results so we can easily prioritize our results over the less than fragrant odor. But the results!!!
My daughter lost 40% of her hair a yr ago to severe scalp ezcema (+ a trip to St Martin’s beautiful yet salty water). We used other products with marginal success. I started using this product 2 months ago & I already see results. We use it twice weekly as a spot treatment along the crown & nape of her head, and deep condition with it twice monthly. Her locs are growing and more importantly, her edges and nape are recovering tremendously. We’re going to keep at it!! We like the texture (moist but not sticky), it leaves her locs moisturized but not weighed down. Her hair is drinking it up. Will repost after 2 more months.
