"Nothing comparable to it." -- Mathematics Teacher. This comprehensive three-part treatment begins with a consideration of the simplest geometric manifolds: line-segment, area, and volume as relative magnitudes; the Grassmann determinant principle for the plane and the Grassmann principle for space; classification of the elementary configurations of space according to their behavior under transformation of rectangular coordinates; and derivative manifolds. The second section, on geometric transformations, examines affine and projective transformations; higher point transformations; transformations with change of space element; and the theory of the imaginary. The text concludes with a systematic discussion of geometry and its foundations. 1939 edition. 141 figures.Binding Type: Paperback

Clean product
This is a great value for the price you pay for the product. It’s easy to use. It does have a gel type consistency, That’s very easy to put on your face. It does not have any lingering smell or odor. And it does a nice job of helping to absorb extra oil on my face.

Good for oily skin/not overly drying!
Love this!! My skin actually feels a lot less oily during the day and it doesn’t dry my skin out either. The smell is a tiny bit weird but it doesn’t really bother me and it dissipates quickly after applying.

Not for me
This in combination with the aloe-ph balancing face wash was not a good fit for my skin. It had me break out with cystic acne. I went back to Hydro Boost and it cleared up in a week. But that’s for my skin. Also, I didn’t care for the consistency of the product.
