"Altogether a most instructive, entertaining, and esthetically pleasing book." -- Science.Since the ancient Greeks, the visualization of space has been a challenge that has intrigued men of learning. Through centuries of thoughtful looking, a number of three-dimensional figures or polyhedral, as the Greeks called them, have been discovered, admired, and wondered at for their mathematical elegance and beauty. And they have been put to use in remarkably diverse ways by engineers and builders, chemists and crystallographers, architects and sculptors.
This book describes very clearly and simply, and illustrates with beautiful photographs of models, a great number of three-dimensional figures, all but a few consisting of plane faces bounded by straight lines. It examines the nine regular solids -- the five commonly called Platonic, described by Theaetetus in the fourth century B.C., and the four called Kepler-Poinsot, two each of which were discovered by Kepler and Poinsot many centuries later. And it examines many variations obtained by truncation, stellation, dualization, and compounding.
Writing for the layman as well as the student or professional in mathematics, Alan Holden explains the structure of the figures and demonstrates how they can be used to explain mathematics visually rather than by symbol systems, an effort hailed by Scientific American magazine as "a victory of clear, connected thinking over the theorematic method." At the end of the book the author includes a section containing instructions for constructing cardboard models.

Makes me look older - Not for me!
This review is for the 05 Dark Beige color of the La Roche-Posay Toleriane Teint Mattifying Mousse Matte Foundation for Oily Skin and Sensitive Skin.
Disclaimer: This review was written by my wife!
We ordered "Honey Beige" and received "05 hâlé - Dark beige", which is not one of the colors offered on the product page. Hâlé means sunburned or tanned, and it is for darker skin, not for the darkest skin tones. It’s too dark for me, as I usually use the second lightest color for foundations.
PROS
The foundation is not fragrant like some of their products
Does not irritate my skin at all
Does not give a cakey look
Covers pores and uneven skin colors well
Looks beautiful right after the application
CONS
In less than a couple of hours, my skin, especially forehead area, looks almost exactly like the texture of "saffiano printed calf skin", with numerous fine straight-line wrinkles going both vertically and horizontally. I could not believe that, so I tried the foundation with and without moisturizers and foundation bases, but my forehead still ended up in looking like the material with which my purse is made. I don't even have visible wrinkles on my forehead without the foundation, so it ended up making my skin look far worse, rather than better.
Not recommended.

Very good foundation
So far, this is working very well for me. It is a little dark for my winter color, but I lighten it with a bit of moisturizer. In the summer when my skin gets more sun, the shade should be perfect.

Light and airy
It is a mousse and goes on so light and airy. Love the way it feels. I dont need a lot of coverage, this went on natural and thin, which was exactly what I need.

Saved my skin barrier!!
I rarely write reviews, but this product truly deserves it. I have sensitive, dry skin with mild to moderate rosacea that became even more fragile after chemotherapy. While trying to repair my skin barrier, I overdid it with actives and completely wrecked my skin — it was red, raw, burning, and peeling.
I turned to ChatGPT for help, and this Avene Cicalfate+ was one of the top recommendations. I started using it about three weeks ago, and wow — the difference is incredible! My skin has healed beautifully. The redness is dramatically reduced, the irritation is gone, and my skin feels soft, smooth, and calm again.
The texture is soft and luxurious without being sticky. I love that there’s no noticeable scent, which is perfect for sensitive skin. It arrived well packaged and intact. For the results it delivers, I consider it an amazing value and will absolutely repurchase again and again.
If you’re on the fence about trying this, go for it — it truly rescued and revived my skin barrier. This is now a permanent part of my routine and 100% a holy grail product for me!
