Description
Think Like a MathematicianWhen we learn about abstract mathematical concepts from prime numbers and fractals to aspects of calculus the most common question is often: when on earth will I need this? To many of us, so called 'pure' mathematics is downright baffling. Yet, these concepts are what underpin the world we live in, from internet security to the transmission of radio waves. When you start to think like a mathematician, the secrets of technology and modern life suddenly

Would buy another
Color: Olive Green, Size: XX-Large
Very lightweight and seems to be water resistant. It’s also a little bit on the longer side, which is great to cover your butt when you bend down!

Comfortable, Flexible, and Ideal for Mild Weather Play
Color: Cream, Size: Large
Great hoodie, exactly what I was looking for. I wanted something lightweight that I could comfortably play golf in, especially in the 50–60°F range. The material is stretchy, polyester-based, and allows for great flexibility during swings, which is a big plus on the course. It provides enough warmth without feeling heavy or overheating as you play. The sizing was spot on as well. I would definitely recommend this to anyone looking for a performance hoodie for mild, cooler golf weather.
