In addition to serving as an introduction to the basics of point-set topology, this text bridges the gap between the elementary calculus sequence and higher-level mathematics courses. The versatile, original approach focuses on learning to read and write proofs rather than covering advanced topics. Based on lecture notes that were developed over many years at The University of Seattle, the treatment is geared toward undergraduate math majors and suitable for a variety of introductory courses.Starting with elementary concepts in logic and basic techniques of proof writing, the text defines topological and metric spaces and surveys continuity and homeomorphism. Additional subjects include product spaces, connectedness, and compactness. The final chapter illustrates topology's use in other branches of mathematics with proofs of the fundamental theorem of algebra and of Picard's existence theorem for differential equations.
"This is a back-to-basics introductory text in point-set topology that can double as a transition to proofs course. The writing is very clear, not too concise or too wordy. Each section of the book ends with a large number of exercises. The optional first chapter covers set theory and proof methods; if the students already know this material you can start with Chapter 2 to present a straight topology course, otherwise the book can be used as an introduction to proofs course also." -- Mathematical Association of America

Matcha
Flavor Name: Culinary, Size: 1.06 oz (Pack of 1)
I haven’t decided if I really like Matcha, as I got this, just to find that out. I find that the packaging is interesting, and it is best, probably, to store it in the package it comes in. It has a mild flavor, and I am just making tea with it, as I don’t bake any more. It is a bright green powder with a smooth, mild taste, and in a clever package.

A Premium Matcha Experience for the True Connoisseur
Flavor Name: Culinary, Size: 1.06 oz (Pack of 1)
I recently had the pleasure of trying the Jade Leaf Matcha Organic Premium Ceremonial Grade Matcha Green Tea Powder, and it truly lives up to its reputation as a high-quality product. As someone who enjoys matcha regularly, I was eager to compare this offering to others on the market, and I have to say I was very impressed.
The first thing I noticed was the vibrant green color of the powder. It’s a rich, deep green that is indicative of the quality and freshness of the leaves. When prepared, the tea has a smooth, silky texture and a natural sweetness that makes it enjoyable both on its own and as an addition to smoothies or lattes. I appreciate that this matcha doesn’t have the bitterness that can sometimes accompany lesser-quality varieties, making it a perfect choice for ceremonial use or a relaxing daily treat.
As a ceremonial grade matcha, it’s clear that Jade Leaf has carefully sourced and processed the tea leaves. The flavor is balanced and complex, with grassy, vegetal notes followed by a subtle sweetness. It has the perfect level of umami, which is an essential characteristic of a high-quality matcha. I’ve tried a variety of brands, but this one stands out for its consistency and superior taste.
The packaging is also noteworthy. The resealable bag ensures the matcha stays fresh, which is crucial for preserving its delicate flavor and antioxidants. It’s easy to scoop out the right amount without making a mess, and the instructions on the back are clear and helpful for those new to preparing matcha.
Whether you’re a seasoned matcha drinker or new to the world of green tea, this Jade Leaf matcha provides a top-notch experience. I highly recommend it for anyone looking for an authentic, high-quality matcha that delivers excellent taste and a sense of calm and clarity with every sip.

Not an affordable option for organic matcha
Flavor Name: Culinary, Size: 1.06 oz (Pack of 1)
Great product however very misleading on the serving amount per package. For a full flavor robust cup of matcha from this product you will get an average of 15 servings. There are much better affordable options available.

It has no sugar
Flavor Name: Culinary, Size: 1.06 oz (Pack of 1)
Very matcha taste and texture. I used this to create a matcha butter cream for my enchanted garden themed cupcakes and it was so delicious. There was no spiciness and I was able to use the rest to make matcha for the kids so I definitely got a good value for my money. I did not have any digestive problems using this. As I did mix it with ripple non dairy milk
