Mathematics in Magic - "Dissecting Methods" Tricks, tutorials, and essays from Steven GoodwinOver the last 10 years, mathematics and technology are two areas that magicians have been more willing to embrace. So, it is with that in mind, I thought that if people are less scared of the maths involved in some magic, it would be a good time to formally expand and re-release these notes which explain effects that use mathematics and - more importantly - how and why the maths work.
By understanding the mechanics behind these effects you can easily adapt and expand the trick in new and interesting ways that would be impossible otherwise. You can also prove that the trick will work in every case through simple mathematics and reasoning, without having to test every single possibility to spot the cases where they don't work.

"Mathematics in Magic is an excellent book filled with clever applications of mathematical principles which have been expertly disguised and turned into 'magical gems'. You will love Steven Goodwin's take on the Gilbreath Principle, pick a number effects, the forcing matrix and the magic square, to name but a few. Maths can be a wonderful, sneaky and devious vehicle for magic, as this book proves!"
- Chris Wardle, author of 'Quirky Forces' and 'Self-Working Wonders'.
"As someone who doesn't typically do mathematical magic, the greatest praise I can offer is that I understood it."

Beautiful Panties for and Excellent Value
These are beautiful panties for the price! I truly love their packaging. As they make one feel beautiful and it is very inclusive. They were arrive in an hygienic plastic packaging within a colorful envelope. All of the underwear are shaped in bikini style, and they also have a beautiful lace trim all around. I really like the warm colors of this pack that I chose and I also enjoy the beautiful feel and look of the lace they are made out of. Really good quality and I love how breathable and comfortable the cotton is. Depending on what one is wearing these cotton underwear may be somewhat seamless under clothes. They fit really well and they are super comfortable on. I really like the quality of these and the value. I really enjoy the undergarments from this brand. I recommend!

Soft, stretchy, comfortable!
As a CIS male, I made the switch to women's panties years ago... they just fit better, don't ride up anywhere, and hold the 'boys' better. These panties are no exception. Being a larger man physically, I usually order panties in the XXL to 3X range. These XXL just fit. They are made from 95% Cotton and 5% Elastane, which I have come to prefer (the elastane) in underwear as they help regulate temperature. The lace is not bothersome at all, and the back side show your butt like a pair of cheekies, but give plenty of coverage. The colors are different from what I normally wear, but I'll take comfort over fashion anyday, especially when dealing with down there. The fabric is soft and stretchy, and I was able to wear these all day without having to adjust much at all. Nice panties for this man!

Great quality!
My wife loves these panties. She says they fit great, they are very soft and comfortable, and best of all they hold up very well when machine washing and drying. Now that she's put them to the test, I just ordered her more.
