Mathematician and popular science author Eugenia Cheng is on a mission to show you that mathematics can be flexible, creative, and visual. This joyful journey through the world of abstract mathematics into category theory will demystify mathematical thought processes and help you develop your own thinking, with no formal mathematical background needed. The book brings abstract mathematical ideas down to earth using examples of social justice, current events, and everyday life - from privilege to COVID-19 to driving routes. The journey begins with the ideas and workings of abstract mathematics, after which you will gently climb toward more technical material, learning everything needed to understand category theory, and then key concepts in category theory like natural transformations, duality, and even a glimpse of ongoing research in higher-dimensional category theory. For fans of How to Bake Pi, this will help you dig deeper into mathematical concepts and build your mathematical background.

Nice product
Size: 8 Fl Oz (Pack of 1)
You smell the vanilla much more than the lavender. The lotion is nice, and smooth.

Love this cream
Size: 18 Fl Oz (Pack of 1)
Love the smell and feel of this cream. It doesn’t leave my skin feeling too greasy, leaves it feeling soft. I know it says it’s for babies but I enjoy it also, so I think it’s also great for adults. The price was reasonable also.

This is such a convenient little kit for trips, beach days, or keeping in the car. Definitely a must‑have for anyone who loves being outdoors.

Travel size products, best sunscreen out there.
Style: Original, Style: Original
Great as always but picture is misleading a bit, this is the small travel size bottle not the full size. I should have read better, still like the set nonetheless of course. Heres a picture for comparison.
