Love Triangle : The Life-changing Magic of TrigonometryExplore the life changing magic of trigonometry with Matt Parker, stand up mathematician and No. 1 bestselling author of Humble PiWhy can no two people ever see the same rainbow? What happens when you pull a pop song apart into pure sine waves and play it back on a piano? Why does the wake behind a duck always form an angle of exactly 39 degrees? And what did mathematicians have to do with the great pig stampede of 2012? The answer to each of these

Explore the life-changing magic of trigonometry with Matt Parker, stand-up mathematician and No. 1 bestselling author of Humble PiWhy can no two people ever see the same rainbow? What happens when you pull a pop song apart into pure sine waves and play it back on a piano? Why does the wake behind a duck always form an angle of exactly 39 degrees? And what did mathematicians have to do with the great pig stampede of 2012? The answer to each of these questions can be found in the triangle. In Love Triangle, stand-up comedian, ex-maths teacher and Sunday Times number one bestselling author Matt Parker is on a mission to prove why we should all show a lot more love for triangles, along with the useful trigonometry and geometry they enable. To make his point, he uses triangles to create his own digital avatar, survive a harrowing motorcycle ride, cut a sandwich into three equal parts, and measure tall buildings while wearing silly shoes. But soon these hare-brained experiments begin to reveal a genuinely important truth: triangles are the hidden pattern beneath the surface of the contemporary world, used in everything from GPS to CGI via Spotify streaming, the play button and your best mate's triangle tattoo. Join Matt Parker as he demonstrates why there's more to triangles than Pythagoras and SOHCAHTOA. Triangles are everything and everything is triangles.

Easy To Use
These work great for a really good price. I love using these when I'm making dishes that would be difficult to clean otherwise.

Value, Durability, Everyday Use
What I liked: - Price-to-value is the standout. These were significantly better priced than similar packs I’ve bought from local grocery stores and big discount retailers. - For everyday, disposable use—think casseroles, baked pasta, brownies, roasted veggies—the lighter weight is perfectly fine. - They stack neatly and are easy to store, which matters when you’re buying in bulk. What I didn’t like: - They’re a bit flimsier and not as thick as the store-brand pans I’ve used before. You can feel the difference when you handle them. - For heavier dishes (large lasagnas, big roasts, or anything dense with sauces), a single pan can flex more than I’d like. How I used them: - Over the past couple of weeks, I’ve used these for baking brownies, roasting chicken thighs with vegetables, and prepping freezer meals. When I expected more weight or lots of liquid, I doubled up the pans, which solved the flex issue and kept everything stable. - I also tested bending one to compare sturdiness. In the accompanying video, you’ll see me gently flexing the pan to show the “give.” In the photo, I placed this pan next to a thicker pan I bought at a regular store so you can see the difference in gauge. My takeaway: - If you need heavy-duty pans for very weighty dishes, these aren’t a perfect one-for-one replacement for thicker, premium options. However, for routine baking, storage, and serving—especially when you plan to toss the pan afterward—the cost savings make a lot of sense. - Doubling them for heavier recipes is a simple workaround that maintains stability while still keeping the overall cost lower than buying thicker single-use pans. Verdict: - I’ll be purchasing these again for everyday use and bulk meal prep. The value is strong, and the performance is solid when you match the pan to the job or double up as needed.
