Kline is a first-class teacher and an able writer. . . . This is an enlarging and a brilliant book. ― Scientific AmericanDr. Morris Kline has succeeded brilliantly in explaining the nature of much that is basic in math, and how it is used in science. ― San Francisco ChronicleSince the major branches of mathematics grew and expanded in conjunction with science, the most effective way to appreciate and understand mathematics is in terms of the study of nature. Unfortunately, the relationship of mathematics to the study of nature is neglected in dry, technique-oriented textbooks, and it has remained for Professor Morris Kline to describe the simultaneous growth of mathematics and the physical sciences in this remarkable book. In a manner that reflects both erudition and enthusiasm, the author provides a stimulating account of the development of basic mathematics from arithmetic, algebra, geometry, and trigonometry, to calculus, differential equations, and the non-Euclidean geometries. At the same time, Dr. Kline shows how mathematics is used in optics, astronomy, motion under the law of gravitation, acoustics, electromagnetism, and other phenomena. Historical and biographical materials are also included, while mathematical notation has been kept to a minimum.
This is an excellent presentation of mathematical ideas from the time of the Greeks to the modern era. It will be of great interest to the mathematically inclined high school and college student, as well as to any reader who wants to understand ― perhaps for the first time ― the true greatness of mathematical achievements.

Lots of extras!
Size: 2+12+12+2 pack
The brushes are a bit flimsier than the original but otherwise fine. I needed it for the rectangular filters more than anything

EUFY 11S
Size: 2+8 pack
Used to replace the ones for my EUFY 11S vacuum. They fit just like the ones and got my vacuum back to cleaning really good. Didn’t realize how loud my vacuum had become until I replaced these parts.

Rejuvenates your Robovac, but one caution
I was a little wary buying third-party aftermarket parts for my Eufy Robovac 30c, however, all the parts in this kit are virtually identical to OEM parts. I replaced all three brushes and all three filters and let it loose on my Golden Retriever-inhabited living room. I can honestly say the result was a 50% increase in the amount of fur collected. I suspect that over time there is a loss of performance so gradual that it's easy to not notice. I assume the new filters returned the vacuum power to it's original level of suction was a big factor.
When I was browsing through all the available choices here on Amazon, a plastic "ring" kept appearing in many of the product images, however, people did not know what it is for or simply did not get one in their shipment. If you look at the photos I've attached one can see that I did indeed get one and figured out its purpose, to remove fur and/or hair from the horizontal brush.
The bottom line is that I would definitely buy this item again.
===========
EDIT, four weeks later: Since replacing the main roller brush with the one included with this product, I have experienced several “Roller brush is stuck” shutdowns and alerts. In each case, there has been nothing tangled in the brush and the brush was free to spin. I have to say it’s quite annoying to come home expecting the floor to be cleaned but only to find this error long before the job was finished. Today it gave this error twice in one cleaning cycle. I never experienced this problem with the OEM roller brush.
