2:10 PM | Spatiologies – Vittorio Giorgini
Walking Tall – Vittorio Giorgini [1980-81] Vittorio Giorginis early architectural works allude to the topological features of continuous surfaces like the Möbius strip or the paradoxical, and non-orientable, Klein bottle. His signature compound curvature buildings such as the Casa Saldarini in Italy and the Liberty Center in New York State (unfinished and latter demolished) expose […]

(Click on the cartoon to see the full image.) (C)Copyright 2014, C. Burke.Or possibly labeled "Passion, Death, Resurrection"? Good Friday is part of the Paschal Triduum, which can also be spelled "Pascal", but I wanted to avoid confusion and basically hang a lampshade on it.

mathani: Get you best paper, cut a circle and fold it, fold it so that the circumference falls on a fixed point inside. Repeat, using random folds. Now see the creases. This is how you paper-fold an ellipse.

6:55 PM | "If Tomorrow Starts Without Me"
My cousin Patricia (she'll always be "Patty" to me) read the following poem at her mother's funeral yesterday. (That would be my Aunt Pat.) There wasn't a dry eye in the place. And if that didn't get you, then her sister Debbie, in her eulogy, remembering those who have left us since last August did: my Mom, their sister Barbara, my niece Lisa and most recently, our cousin Mary Ann. To that, I'll add a few more: my Uncle Eddie (on the other side of the family) last week, my colleague Ms. […]

The Fluctuating Math Errors in Americans’ Tax Returns 4:40 PMApr 15 By Mona Chalabi Seeing as Tuesday night is the deadline for filing tax returns, and seeing as data is FiveThirtyEight’s raison d’être, I was excited to find a set of statistics titled “Math Errors on Individual Income Tax Returns, by Type of Error.” Even better, that data has been published for tax years from 2001 to 2012. It’s unsurprising that some Americans make mistakes on their taxes; the 1040 […]

Scale-Free Mathematics in Matzah? By Samuel Arbesman   04.14.14 Tonight is Passover. And the most well-known food of the holiday is matzah, the cracker-like flatbread. Within this food we can find some complexity science goodness. At one part of the Seder meal, we break one piece of matzah into half. Now, for anyone who has actually tried this, one recognizes the great difficulty in doing so. Matzah does not break evenly. It too often breaks along fracture points that cause a piece of matzah […]

MIT Whizzes Invent Magical Furniture That Changes Shape on Demand By Liz Stinson   04.15.14 Furniture has traditionally been a static thing. We sit at our tables, in our chairs that hold their stiff, rigid shape no matter what we’re doing or how we’re feeling. As our homes become smarter and more personalized, furniture has almost wholly been left out of the revolution. It’s a shame. Just imagine if your sofa could sense how you’re feeling when you get home from work. To stave off […]

1:06 PM | Funny How Things Work Out
It had been my intention, if I could muster the discipline and determination, to have a new comic each day this week because I'm off. Funny how things work out. It seems like every day is booked with something, the first three days being the worst. Sure, I might have something by Thursday, but that's hardly "every day" of the week. That's catch-up time. There will be an update, and if I can spend Friday working on things, I'll plan out next week ahead of time. I hope. And next Monday and […]
