The Cult of Pythagoras: Math and MythsIn this follow up to his popular Science Secrets, Alberto A. Mart nez discusses various popular myths from the history of mathematics: that Pythagoras proved the hypotenuse theorem, that Archimedes figured out how to test the purity of a gold crown while he was in a bathtub, that the Golden Ratio is in nature and ancient architecture, that the young Galois created group theory the night before the pistol duel that killed him, and more. Some stories
In this follow-up to his popular Science Secrets, Alberto A. Mart nez discusses various popular myths from the history of mathematics: that Pythagoras proved the hypotenuse theorem, that Archimedes figured out how to test the purity of a gold crown while he was in a bathtub, that the Golden Ratio is in nature and ancient architecture, that the young Galois created group theory the night before the pistol duel that killed him, and more. Some stories are partly true, others are entirely false, but all show the power of invention in history. Pythagoras emerges as a symbol of the urge to conjecture and "fill in the gaps" of history. He has been credited with fundamental discoveries in mathematics and the sciences, yet there is nearly no evidence that he really contributed anything to such fields at all. This book asks: how does history change when we subtract the many small exaggerations and interpolations that writers have added for over two thousand years? The Cult of Pythagoras is also about invention in a positive sense. Most people view mathematical breakthroughs as "discoveries" rather than invention or creativity, believing that mathematics describes a realm of eternal ideas. But mathematicians have disagreed about what is possible and impossible, about what counts as a proof, and even about the results of certain operations. Was there ever invention in the history of concepts such as zero, negative numbers, imaginary numbers, quaternions, infinity, and infinitesimals? Mart nez inspects a wealth of primary sources, in several languages, over a span of many centuries. By exploring disagreements and ambiguities in the history of the elements of mathematics, The Cult of Pythagoras dispels myths that obscure the actual origins of mathematical concepts. Mart nez argues that an accurate history that analyzes myths reveals neglected aspects of mathematics that can encourage creativity in students and mathematicians.Binding Type: Paperback

VERY comfortable & cute sandal!
Size: 9, Color: Cognac
I needed a pair of comfortable sandals for this summer & I really got lucky with these. I have a lot of arthritis in my feet & even my $100(+) tennis shoes don’t keep the pain away. I may start with tennis shoes at the beginning of the day but 1/2 way through I slip on the Hey Dudes & all is much better!
These sandals are versatile, I have worn them with jeans & shorts. They would also look nice with a skirt. They are cute & comfortable! Not only are they lightweight, it feels like you are walking on air because the sole is so cushioned.
One thing I do want to mention is the fact there is A LOT of room given toward the front of the shoe. The strap that goes over the ball of your foot is looser than I am used to, even with wide feet. You aren’t able to make adjustments. When I first put them on I didn’t think I would like it but after wearing them every day for the past month I know I do.
I would recommend these sandals & wonder if I should stock up in case they stop making this style??

Cushy softness
Size: 8, Color: Ivory
I’m normally a 7W and originally ordered the 7 and it was almost a perfect fit if not for my high instep. Exchanged for an 8 and they fit great just a little loose in the toe strap but I can make it work.

Ripping with minimal wear.
Size: 8, Color: Black/Black, Size: 8, Color: Black/Black
I really wanted to love these. This is my first pair of HeyDudes, and I am pretty disappointed. I don't have wide feet. They fit perfectly, and were super comfortable. But they are already ripping and I haven't even worn them 5 times. I didn't even wear them long or walk a lot in them.

Perfect everyday Watch
Color: Grey, Color: Grey
Super happy with this watch. It looks really clean and goes with pretty much anything dress it up or wear it casual. The blue face is fire in person and catches the light really nicely.
Feels solid on the wrist, not too heavy, and the quality is definitely there. I’ve been wearing it almost every day and it still looks brand new.
For the price, you really can’t beat it. Great everyday watch that looks way more expensive than it is. Would 100% buy again
