Paul Erd s, one of the greatest mathematicians of the twentieth century, and certainly the most eccentric, was internationally recognized as a prodigy by age seventeen. Hungarian-born Erd s believed that the meaning of life was to prove and conjecture. His work in the United States and all over the world has earned him the titles of the century's leading number theorist and the most prolific mathematician who ever lived. Erd s's important work has proved pivotal to the development of computer science, and his unique personality makes him an unforgettable character in the world of mathematics. Incapable of the smallest of household tasks and having no permanent home or job, he was sustained by the generosity of colleagues and by his own belief in the beauty of numbers.Witty and filled with the sort of mathematical puzzles that intrigued Erd s and continue to fascinate mathematicians today, My Brain Is Open is the story of this strange genius and a journey in his footsteps through the world of mathematics, where universal truths await discovery like hidden treasures and where brilliant proofs are poetry.

Smells awful
Size: 8 Ounce (Pack of 1)
This smells awful. Like dead roses. I find it does make skin smoother however it does leave a sticky residue that lasts.

Dove retinol
Size: 8 Ounce (Pack of 1)
This retinol is super good. It’s moisturizing and leaves my skin glowing all day. The price for it isn’t bad either.

Amazing facial sunscreen
Color: Tinted
The tinted Anthelios is my go to sunscreen for summer. The problem with most facial sunscreens is that they feel like a heavy cream and they leave a ghastly whitish color. Anthelios is different. It is light, easy to apply, and dries quickly to a soft matte finish. There is no white cast, no discernible “sunscreen odor”. It softens facial imperfections without the weigh down of makeup. Anthelios doesn’t clog your pores or settle into lines. It just leaves a natural fresh look. My skin but bettter. I’ve purchased it multiple times and will continue to use Anthelios. Buy it - you won’t be disappointed by this one.

Lightweight, Flawless Coverage & Reliable Sun Protection A Daily Must-Have!
Color: Tinted
I’ve been using this sunscreen for a few weeks now, and overall I’m very impressed. The texture is extremely lightweight and fluid, which makes it easy to apply evenly without feeling or greasy on the skin. It absorbs quickly and leaves a soft, matte finish that works well under makeup.

My favorite Sunscreen
Color: Tinted, Color: Tinted
I’ve been using La Roche-Posay Anthelios Ultra-Light Fluid Facial Sunscreen SPF 40 for a few years now, and it’s still one of my favorite daily sunscreens. The formula is truly lightweight and absorbs quickly without feeling greasy or heavy on the skin. It layers well under makeup and doesn’t leave a noticeable white cast, which I really appreciate.
I also like that it provides reliable sun protection while still feeling comfortable enough for everyday use. Even after trying other sunscreens over the years, I keep coming back to this one because it works so well for my skin. Highly recommend for anyone looking for a lightweight, non-greasy daily sunscreen.
