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.

price fair for the value
Simple but effective addition to a daily routine. The stainless steel feels sturdy and much nicer than plastic versions, and the dual handles make it easy to control. It cleans well without feeling harsh and rinses off quickly after use. Compact enough to toss in a toiletry bag too. Good basic hygiene tool that does what it’s supposed to.

Actually helps dry mouth!
I’m giving this product 4.5/5. It works really well for dry mouth during sleep. I recommend starting with 1 tablet and adding a second one only if necessary. (I require 2 tablets at night). This is called “slightly sweet” and is relatively tasteless with a hint of sweetness.
During daytime usage, I’ve been using 2 tablets at a time. The only issue I have during the day is that if I can’t drink on a regular basis I get the white coating from the tablets in the corners of my mouth. I do think that this is the next best product to use when taking sips of water isn’t possible. Works as stated and easily adheres to your gum line/partial tooth. I place them in the back of my mouth and they are not noticeable to others. Added bonus, they don’t leave a slimy coating on your teeth the way a mouth rinse does. Product performs better than expected! If you have dry mouth for any reason please consider giving these a try!!! I wish I would have known about them years ago!!!

Works for dry mouth
Suffer from dry mouth and these disc size tablets stick to my gums, helping keep my mouth moist through the night. Brown side sticks to your gum. Contain xylitol so s little sweet. Dentist recommended them.
