This is the third collection under the rubric ''That's Maths''.
The first volume, ''That's Maths: The Mathematical Magic
in Everyday Life'', was published by Gill Books in 2016. The second,
''That's Maths II: A Ton of Wonders'', was published for Logic
Press in 2020. Both volumes were very favourably reviewed.

This collection includes essays on a wide range of topics in both
pure and applied mathematics. Chapters such as one on the beautiful
theory of complex variables, illustrate the ''elegant abstraction''
mentioned in the subtitle, while chapters on mathematics in mechanics, astronomy, networks,
freak waves and music demonstrate its ''eclectic applications''.

The book is suitable for everyone with an interest in mathematics,
whether or not they have studied the subject beyond secondary school
level. Some chapters are purely expository; others go deeper into
their subjects and are at a more advanced mathematical level. The
first three quarters of the book (48 chapters) require no advanced knowledge.
The final quarter (16 chapters, each marked by a star)
involve some undergraduate maths. These should give readers a flavour of
some more advanced mathematics.
The chapters in this book are all short, generally about four
pages. They can be read in sequence, with constantly changing
themes, or in random order. The book should be appreciated by
anyone with an interest in mathematics and science. In particular,
teachers of these subjects, at both school and university level,
should find a cornucopia of material to add a sparkle to their
classes.

Many of the essays in this collection have appeared in the regular
column ''That's Maths'' in The Irish Times or on Peter Lynch's mathematical
blog, thatsmaths.com. All have been fully revised for
this book.

Recommended! A Must-Have for Sun Protection
Size: 1.5 Ounce (Pack of 1)
I've been using the Neutrogena Ultra Sheer Dry Touch SPF 50 Mineral Sunscreen Stick for a while now, and I can't imagine going out without it. This convenient stick sunscreen provides excellent sun protection without leaving behind a greasy or sticky residue. One of the things I love most about this product is the way it sits on my skin. It gives a subtle, healthy-looking glow that's far from chalky or unnatural. The "whiteness" it provides is subtle and believable, adding a touch of radiance to my complexion. I get compliments whenever I apply this on my face! The stick format is incredibly easy to apply and reapply throughout the day. It fits perfectly in my purse and doesn't require any messy fingers. The formula absorbs quickly and leaves my skin feeling smooth and protected. I use this sunscreen as a touch-up after applying my regular sunscreen, especially on areas like my face and neck. It provides an extra layer of protection and ensures that I'm fully covered from the sun's harmful rays. If you're looking for a reliable and effective sunscreen that won't leave you feeling greasy or sticky, I highly recommend the Neutrogena Ultra Sheer Dry Touch SPF 50 Mineral Sunscreen Stick. It's a must-have for anyone who wants to protect their skin from the sun while maintaining a healthy, radiant glow.

Comfortable wear
Size: 1.5 Ounce (Pack of 1)
Spreads so easy - the big deodorant dispenser looks weird but it takes fewer swipes. Is soft and you can see where you applied. Must rub it in though. Dries down matte - excellent formula. Spreads easily and sets very quickly. Blurring effect is nice on my old wrinkled face. Not drying or tightening of skin feeling - comfortable and never heavy or tacky unless it’s more than 2 reapplications. Gets too white too. Slight cast but a LOT less than others. It takes more than 2 layers on me (Mac NC 20-25) I think this one is it. Not hard and chalky, agreeable haze but the finish is dry and pores are smoothed over. If they ever made a tinted stick like this I’d feel like I’ve won the lottery

Does the job, but it does whiten.
Size: 1.5 Ounce (Pack of 1)
It's a nice sunscreen, but I have light skin and it still lightens it even more. It can be blended out to not be as noticeable though. So, if you wanted a hands free sunscreen like I did, this may not work for you since you'd need to blend it out with your hands in order to reduce the whitening effect. Also, you should warm it up with your fingers first before applying it to your face so it doesn't drag your face and glides more easily. Skin wise, no reactions from it. I have slightly sensitive skin and do have acne and it never got worse from using this(used almost daily for 5 months now). If you use makeup, I'm 100% sure this with move your makeup so be careful with that, I'd put it on before and use something else for reapplication after. Texture is smooth and a tad sticky/greasy I'd say. Not 100% matt, but not glossy.

Good sports sunscreen for face! Blends noticeably less than chemical sunscreens
Size: 1.5 Ounce (Pack of 1)
My use case: A sand volleyball tournament that goes from 9am in the morning till 6pm at night in the summer Texas sun. My primary concerns: prevents sunburn, doesn't get in my eyes when sweating. I'm not overly concerned with how well this sunscreen blends in - I don't want an opaque white paste on my face, but I'm also a sweaty sandy mess, so appearance isn't my top priority. For reference, I'm white but tan easily. This sunscreen stick works well for this purpose! I can sweat profusely as you would expect, but there is no stinging in my eyes like I get with chemical sunscreens. It also has broad spectrum protection against UVA and UVB including long wave UVA. If you want a daily sunscreen to prevent aging that appears invisible, this may not be for you. But if you want a good sports sunscreen for face that won't irritate eyes, this is it!

great sunscreen for face
Size: 1.5 Ounce (Pack of 1)
this is my favorite stick sunscreen for the face. it does have a slight white cast when you first apply it but it goes away once it’s been rubbed into the skin. so many sunscreens say they have a “non-sting formula” but this is the only one i have used that truly doesn’t burn/sting the eyes when applied on the eyelids or when you sweat into your eyes. doesn’t have that traditional “sunscreen smell” either. it leaves a healthy glow to the skin as well. three swipes on all areas of the face is enough coverage. it is a little pricey but i think it lasts quite awhile. highly recommend trying this sunscreen.
