Although the concept of space is of fundamental importance in both physics and philosophy, until the publication of this book, the idea of space had never been treated in terms of its historical development. It remained for Dr. Jammer, noted scholar and historian of science, to trace the evolution of the idea of space in this comprehensive, thought-provoking study. The focus of the book is on physical, rather than metaphysical, ideas of space; however, philosophical or theological speculations are discussed when relevant. The author has also given special attention to the cultural settings in which the theories developed.Following a Foreword by Albert Einstein and an introductory chapter on the concept of space in antiquity, subsequent chapters consider Judaeo-Christian ideas about space, the emancipation of the space concept from Aristotelianism, Newton's concept of absolute space and the concept of space from the eighteenth century to the present. For this third edition, Dr. Jammer has contributed an extensive new chapter six, reviewing the numerous and profound changes in the philosophy of space since the publication of the second edition.
An abundance of meticulously documented quotations from original sources and numerous bibliographic references make this an exceptionally well-documented book. It is essential reading for philosophers, physicists, and mathematicians, but even nonprofessional readers will find it accessible.

Lightweight tinted SPF that looks beautiful on mature skin
I’ve tried a lot of tinted sunscreens, and this one is honestly one of the nicest I’ve used for everyday wear. The Eucerin Tinted Age Defense SPF 50 feels lightweight, blends easily, and gives the skin a healthy natural glow without looking heavy or greasy.
The texture is smooth and hydrating, and I was pleasantly surprised by how well the tint adapted to my skin tone. It helped even out my complexion while still looking very natural. On mature skin, that is important because many tinted SPFs can settle into fine lines or look dry after a few hours. This one stayed comfortable and looked fresh throughout the day.
I also liked that it layered well over skincare and under makeup without pilling. The finish is more radiant than matte, which gives the skin a healthier and less tired appearance. The addition of hyaluronic acid is a nice bonus because the product feels more moisturizing than many sunscreens I’ve tested.
The packaging is practical, easy to use, and perfect for daily use or travel. SPF 50 protection combined with skincare benefits makes this a great all in one daytime product.
The tint may not work perfectly for every skin tone since it is designed as a universal shade, but on my skin it blended much better than expected.
If you’re hesitating between Eucerin and CeraVe, this one is better for mature skin, a more elegant finish, and higher sun protection since this version offers SPF 50 while many tinted CeraVe options only go up to SPF 30. If you specifically want higher daily protection with a natural radiant finish, this one is definitely the better choice for me.

Eucerin sunscreen spf 50
The best sunscreen I’ve ever had. No white cast, no clogging pores. Goes on smooth and silky. No flaking off. Absolutely love it. I’m a dark skinned black woman for reference

Eucerin for the Win...Again!
I love this tinted sunscreen. It's so lightweight and blends in really well. Since it blends in, it is good for all shades of skin. It doesn't have a strong smell like a lot of other sunscreens have, so that is a huge bonus. So far I'm really loving it. I am definitely a Eucerin girly. I love all things Eucerin at this point.

A hydrating sunscreen but won’t provide the coverage
I’ve been using CeraVe sunscreen, so that’s my baseline. It’s thicker, slightly pigmented, and very hydrating..
Switching to Eucerin felt like moving from a cozy blanket to a light sheet. It’s definitely thinner and less pigmented, so at first it didn’t give me that same immediate glow or coverage I was used to. That said, on its own, it’s still a good sunscreen. It spreads easily, feels comfortable, and does the job without heaviness.
After using it for a while, I’ve kind of settled into a rhythm:
• If I want a bit of coverage and that hydrated, supple finish → I reach for CeraVe
• If I just need straightforward sun protection → Eucerin works perfectly fine
One small downside is the packaging. The pump is convenient, but toward the end, I can already tell there’ll be product left that’s hard to get out since you can’t really squeeze or open it easily.
Overall, I’d say Eucerin is a solid, lightweight sunscreen. Just don’t expect that tinted, slightly “makeup-like” effect if you’re coming from something like CeraVe. It’s more of a quiet, reliable everyday option than a multitasking one.
