Why you should always order the large pizza? We often see these deals, buy 2 for 1! Is this real thing? Maybe for some products, but for sure this will not work for pizza! Nota-a-chance! So let's take a closer look 👀 You need to choose between ordering two small size pizzas, each with radius 10 cm, while on the other side the large pizza, which has a larger radius of 20 cm. We can approach this problem in two ways: arithmetically or maybe we can say visually. The arithmetic method would require from us to calculate the area for each pf the pizzas. Since we are here, let's do that.  Let's denote the area of the small pizza by Pr,  and the area of the large pizza by PR.  Then we have: Pr=p10^2, and PR=p20^2, which equals to Pr=100p, and PR=400p. Can you notice the ratio? Yup! Two small pizzas are altogether 200p, and the large one is 400p. The conclusion if you want to eat more (not always necessary and healthy choice) you should buy the large one! Don't let be tricked. ...

Numero uno  1 The Grapes of Math, but not the children's book 😀 This one is by the author Alex Bellos, (as I was able to do find) a prominent math-book writer. The official name is : "The Grapes of Math, How Life Reflects Numbers and Numbers Reflect Life", 2014 The Grapes of Math is not for the average reader. It may leave the first impression as a unserious or light book, but if you dive deeper, you will see that is mathematically weighty. You need to have some passion for science at least, it doesn't has to be specifically for math. I would that say it requires  math maturity.  Maybe, the best audience will be:  math and science college students, science and math teachers, or engineers.  This book contains many of the famous stories and covers a lot. What I find unique about this book is that in every chapter, on almost every page you can find names, places, theorems, which you can search upon and then delve into your own direction of research.  Number ...
