By: Hideo Nitta, Masafumi Yamamoto, Keita Takatsu, Co Ltd Trend | Series: The Manga GuidesEverything’s gone screwy at Tagai Academy. When the headmaster forces Minagi’s entire class to study Einstein’s theory of relativity over summer school, Minagi volunteers to go in their place. There’s just one problem: He’s never even heard of relativity before! Luckily, Minagi has the plucky Miss Uraga to teach him.
Follow along with The Manga Guide to Relativity as Minagi learns about the non-intuitive laws that shape our universe. Before you know it, you’ll master difficult concepts like inertial frames of reference, unified spacetime, and the equivalence principle. You’ll see how relativity affects modern astronomy and discover why GPS systems and other everyday technologies depend on Einstein’s extraordinary discovery.
The Manga Guide to Relativity also teaches you how to:
–Understand and use E = mc2, the world’s most famous equation
–Calculate the effects of time dilation using the Pythagorean theorem
–Understand classic thought experiments like the Twin Paradox, and see why length contracts and mass increases at relativistic speeds
–Grasp the underpinnings of Einstein’s special and general theories of relativity
If the idea of bending space and time really warps your brain, let The Manga Guide to Relativity straighten things out.

Very soft
Size: Body (20" X 54"), Color: 06 - Sage Green, Number of Items: 1
The color was perfect. It’s very soft. The only thing that I really don’t like is the finish of the opening, it would be better with a zipper closure.

Cool, Comfortable, and Worth Every Penny!
Color: Light Gray, Size: Standard
I’m honestly impressed with these pillowcases! From the first night, I could feel the difference—they stay noticeably cool, which is perfect if you tend to sleep hot like I do. The fabric feels silky smooth against the skin without being slippery, and it’s really gentle on both my hair and face.
I’ve also noticed I wake up less sweaty and more comfortable overall. They fit my pillows well and don’t slip off during the night, which is a big plus. After washing, they held up great—no fading, shrinking, or loss of softness.
If you’re looking for pillowcases that actually help keep you cool and comfortable through the night, these are definitely worth it. I’ll be buying more!

Extremely cold, silky, gentle on hair
Color: White, Size: Queen
This was so cold when I removed it from the package that at first I thought it would be too cold. It was as if it had been in a freezer. I really like how silky it is on my face. (I can't stand a rough feeling pillowcase.) It is also gentle on my curly hair. The pillowcase can warm up from being slept on, but a shift of just a few inches gets back to wonderful cold. I highly recommend this as an extremely cool, silky smooth fabric. These are much colder than my very expensive miracle sheets.

Freaking Amazing 🤩
I never write reviews but these pillow cases absolutely deserve one!!! These are absolutely amazing! So soft and cool! I sweat so bad every night!! I wake up and my hair, shirt and pillow are drenched!!! I slipped these bad boys on as soon as they came in, and let me tell you! They were cold to the touch, I woke up this morning and I wasn’t sweating! I thought $20 something dollars was a little expensive for 2 pillow cases but was totally worth it! We love love love them!🩷🩷🩷Hubby approved😉

Stretchy Material and Cooling Fabric
Color: Light Gray, Size: Standard, Color: Light Gray, Size: Standard
Material: is very stretchy and cools well. It has a zipper which is good because the fabric is very soft and slippery and if it didn’t have a zipper the pillow would not stay in the case.
Durability: zipper works great and material is easy to clean.
Color: I have the gray and my daughter has the pink. Both colors as advertised.
Value: Good value and I got what I expected.
