A revolutionary book from the stand-up mathematician that makes math fun again--now in paperback


Math is boring, says the mathematician and comedian Matt Parker. Part of the problem may be the way the subject is taught, but it's also true that we all, to a greater or lesser extent, find math difficult and counterintuitive. This counterintuitiveness is actually part of the point, argues Parker: the extraordinary thing about math is that it allows us to access logic and ideas beyond what our brains can instinctively do--through its logical tools we are able to reach beyond our innate abilities and grasp more and more abstract concepts.
In the absorbing and exhilarating Things to Make and Do in the Fourth Dimension, Parker sets out to convince his readers to revisit the very math that put them off the subject as fourteen-year-olds. Starting with the foundations of math familiar from school (numbers, geometry, and algebra), he takes us on a grand tour, from four dimensional shapes, knot theory, the mysteries of prime numbers, optimization algorithms, and the math behind barcodes and iPhone screens to the different kinds of infinity--and slightly beyond.
Both playful and sophisticated, Things to Make and Do in the Fourth Dimension is filled with captivating games and puzzles, a buffet of optional hands-on activities that entice us to take pleasure in mathematics at all levels. Parker invites us to relearn much of what baffled us in school and, this time, to be utterly enthralled by it.

Great Kitchen Purchase
Color: Stainless Steel, Size: Medium Size, Color: Stainless Steel, Size: Medium Size
I didn’t realize how much I needed a kitchen scale until I got this. It’s really accurate and makes cooking (especially baking) so much easier and more consistent. The tare function is a game changer—you can zero out the bowl and keep adding ingredients without extra measuring cups. It’s also easy to switch between grams and ounces, which is great for following different recipes. Most digital scales measure very precisely, often down to about 1 gram, which makes a big difference for accuracy. It’s compact, easy to clean, and doesn’t take up much space on the counter. Overall, such a simple tool but makes a big difference—definitely worth having in any kitchen.

Great little scale!
Color: Stainless Steel, Size: Medium Size
Love this little guy! It's small I use it for all my meals. When in a rush I can just toss it in my lunch box and use it at work. Super convenient. It sits on my counter no bigger than a side plate. Worth the money!

Food scale
Color: Stainless Steel, Size: Medium Size, Color: Stainless Steel, Size: Medium Size
This product is worth the price. The only thing is that it kind of doesn’t work sometimes when you are trying to switch the unit and you might have to double click (as shown in my video) other than that the product works perfect for measuring my food and even my liquids. It’s the perfect size not too big and bulky but it also isn’t that small. As you can see in my picture it’s small enough to fit in my drawer (I don’t like to leave it on my counter) it’s a tiny bit bigger than an Alexa.i also like that the price isn’t to high . I would definitely recommend this product! It’s a sturdy product it doesn’t move when you’re putting any items on it. It’s easy to clean off as well. Another thing is it takes batteries ( it takes AAA batteries, just 2 of them) and I liked how it came with batteries inside of them already .

Accuracy is spot on—it measures consistently in grams and ounces, which is perfect for portion control and precise recipes. The tare function works smoothly, making it easy to weigh multiple ingredients in one container. The stainless steel surface is a nice touch—it looks clean and is easy to wipe down after use. The display is clear and easy to read, even in lower light. For the price, it’s hard to beat. It does exactly what you need without any unnecessary extras. Pros: -Lightweight and compact -Accurate and consistent measurements -Easy-to-use tare function -Stainless steel surface (easy to clean) -Great value Cons: -Small size may not fit very large bowls -Basic features (no advanced tracking) Overall: A reliable, no-frills kitchen scale that gets the job done.
