Fibonacci
Title: The Man of Numbers
Author: Keith Devlin, PhD
Publisher: Walker & Company
Genre: Math History
Length: 183 pages
Swirl by Swirl – a child’s picture book – is where it started. We checked it out from the library once, then twice, and finally again and again. It’s about the Fibonacci sequence found in so many spirals in our natural world. We love it. Of course, it has a bit in the back about the Fibonacci sequence and the math involved, and that’s cool too, something to instill in young minds so that the
re is familiarity with the topic before they begin Algebra in their tweens.
Of course, at some point I picked up The Pythagorean Theorem, and there Posamatier mentions Ptolemy and his great work The Algamest as well as Fibonacci’s Liber Abaci. Naturally, I requested these at my local library. “There’s a book about Fibonacci called The Man of Numbers that’s here if you want to read that while you wait for the others to come in,” she told me. Yes, yes, I would like to read that while I wait for the others.
I checked it out.
I ended up starting and finishing it, however, in one sitting while my kiddo made use of the sixty minute literacy computer session I allow her if she’s been good prior to coming to the library that day. It was good. Quick. Informative. And of course, just made me want Liber Abaci even more.
Devlin gives you all the necessary history in the concise nature of a mathematician. He even laments how most mathematicians are concerned about the math and the theorems and not necessarily who originally came up with them or their history, causing much of the history surrounding mathematical ideas to be lost or misconstrued. Who cares? It’s about the numbers.
I care. Historians care. We don’t care as much about the numbers as we do about the theory, the philosophy… we care about math’s heritage more than the practice of being all mathy. At least that’s how I feel. I’ll leave number crunching to my husband and daughter – I’ll just be able to tell them who came up with that particular way to crunch.
With all this caring comes the discovery that Fibonacci’s name wasn’t even Fibonacci. Devlin recounts the fact that the man’s name was Leonardo and he hailed from Pisa. Leonardo Pisano, as the people of that time and culture would say. But he referred to himself as fillies Boracic, “son of Bonacci.” Yet, his father’s name wasn’t Bonacci, so people assumed he meant that he was of the family Bonacci… the Bonacci family evolved and later historian Guillaume Libri coined the name Fibonacci. Hundreds of years later. Leonardo was renamed Fibonacci in 1838.
Fibonacci also referred himself as Leonardo Bigolli… a named once translated would be “Leonardo Blockhead.” Though, Devlin asserts, it’s doubtful that Fibonacci was calling himself a blockhead.
That brings us to our latest picture book selection… Blockhead: the life of Fibonacci. This delightful picture book was written by Joseph D’Agnese and was illustrated by John O’Brien. Even though there’s a lot we don’t know about Fibonacci’s real life or how he came to discover his mathematical findings the way he did – it’s fun to imagine what his life was like and where he might have come up with his self-proclaimed nickname “Bigolli.”
For good measure, we re-read Swirl by Swirl afterward and are looking forward to memorizing a few things in the upcoming months.
The first is from Brahmagupta (quoted in Devlin’s book):
“A debt minus zero is a debt.
A fortune minus zero is a fortune.
Zero minus zero is a zero.
A debt subtracted from zero is a fortune.
A fortune subtracted from zero is a debt.
The product of zero multiplied by a debt or fortune is zero.”
The second are the first ten numbers in the Fibonacci sequence: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55.
The Curious Origins of Tweedledum and Tweedledee
I love factoids like this!
Interesting facts about the surprising history of Tweedledum and Tweedledee
Who is being described? Born in the north-west of England near Manchester, he was a literary man who was also noted in his day for his interest in science and mathematics. In terms of physical appearance, he was known for being particularly tall, considerably taller than average. He gave us Tweedledum and Tweedledee, pioneered a system of code-writing, wrote one of his most famous works for a young girl, and appears to have had an interest in the occult.
The above may sound like a description of Charles Dodgson, better known as Lewis Carroll, but in fact

Adventures in Freelancing
I was scouring the internet looking to see what Cosmo was all about. I’m a freelance writer, I should know these things. Also, I was submitting an article to them after receiving an ad for blog contributors. Of course, I had to consult my college room mate, that’s what gal pals are for, right? “I have no idea what I’m doing…” She read what I wrote, checked it for grammar, and helped me pick my already published content to include on my Cosmo tailored resume.
After I hit send I messaged her, “I did it. I sent it. That would be cool if they picked that up.”
“Agreed,” she responded, “Then I could finally learn YOUR 19 Top Secrets To A Hands-Free Female Orgasm.”
- Like the person you are having sex with – or don’t, sometimes that helps too.
“Both work with my husband,” she piped in.
2. Take a bath and shave your legs. This is an important step to remember when you are over 30 and have children. Or, you know, don’t – if you’re a dirty hippie, get off on the smell of human grease, and think hair friction will truly light your fire.
“Hair friction can help at times, yes. Continue…”
3. Despite all your favorite chick-flicks – don’t order Chinese food in advance. All that fried goodness, fried rice, and MSG will just make you feel gross. You will not have the appeal of a genetically blessed tiny acrobatic Asian after you order Chinese food. You will instead have sweet and sour sauce drippage down your right boob from where you almost lost the chop sticks. You will feel fat and bloaty after *so much* rice, and, to top it all off, you’ll smell like shrimp rolls and crab puffs.
4. Make sure all the children are asleep, or completely preoccupied. Nothing is worse than that ten minute quickie turning into, “But mommy, why can’t I come in? Mommy, I need another fruit pouch. Mommy…” Knock. Knock. Knock. “Mommy…”
“Basically,” my husband says as he reads over my shoulder, “You’re saying people should have sex with somebody.”
“Yes. Of course.”
5. Have sex with a human.
“Yes, hands free otherwise implies non-masturbatory. You’re welcome, Jonathan,” my Emily says to my husband.
“This article is not Cosmo material. You’re supposed to be talking about leading people in the direction of using hands-free toys. Like using a sub-wolfer. Or, rubbing your vagina against a fence post,” my husband continues to say.
I have no idea what he is saying to me right now. I don’t want to get off on a radio… I want to have sex with a person.
“Number six needs to be drive a shitty car with old shocks down a shitty road,” he tells me.
I’ve done that. That works. It was accidental of course.
6. Drive a poorly maintenanced junker.
“Does hands free include my hands? I’m just wondering what your requirements were for hands free,” my husband is way too into this.
7. Use someone else’s hands.
We can explore all our options later…
Pythagoras, History , Music, and Reality
Title: Pythagorean Theorem
Author: Alfred S. Posamentier
Genre: Mathematic History
Publisher: Prometheus Books
Length: 320 pages
I’m not sure why I picked it up. I didn’t even particularly care for math in school. Geometry was not my strongest suit – but it was fairly easy math that I slithered through with the least possible amount of effort of any of my math courses. But I was at the library one day and this geometric tree design was staring at me – I’d been collecting everything I could on trees because I am determined to become a certified arborist by the time I turn 40 – and upon impulse I through it in my “shopping” bag.
It might have been because I saw that it was about the Pythagorean theorem, and just a few years ago I attended a MENSA meeting where Andy Tang spoke on the topic. The lecture was riveting, the discussion entertaining, and the wine pretty great for free stuff. The event coordinator in me wanted to host his art exhibit at one of the bookstores I work with. This didn’t happen, but there was such an exhibit led by him in Austin:
The community art exhibition “Pythagoras (and Austinites) Discovering the Musical Intervals” invites you to discover the story of what Pythagoras heard at the blacksmiths’ workshop. Continuing the tradition of passing down this ancient tale, this art show showcases Austin-area artwork through interactive, musical, and visual interpretations. (https://www.facebook.com/events/308042019293116/)
Whatever it was that possessed me, I picked up the book. I read the book. I enjoyed the book – a lot. More than I could have thought I would enjoy a math book.
Although, let’s be honest, I enjoyed it for the philosophy and history, not so much for the endless diagrams and presentations on how the theorem works. Yeah, yeah, yeah, I took that math class, I get it, and it’s cool, but I was really into the book for the tidbits about Fibonacci and then later, Bosman. Bosman, by the way, is the guy that came up with the Pythagorean tree featured on the front cover.
I read this book for the whole chapter on music – that ties into that Andy Tang lecture I loved so much. I read this book because I was a “Choir Queer” in high school and loved chamber music and found it completely fascinating how much math and music were so intertwined. And of course, any one who does math and attempts music theory ends up asking the same questions:
“[…] do we simiply measure the distances between pitches or do we seek some measurable property of the pitches themselves that allows us to determine their relationships to other pitches […]”
Pythagoras had an answer. And he’s an old, dead dude, and I love reading ancient history and things on or by old, dead dudes. Except, naturally, Pythagoras was a top secret kind of guy and left no writings of his own behind and everything we know about him is second hand at best.)
Which leaves me diving into Philolaus, Plato, and Aristotle, and itching to get into Xenophon and see if anything is mentioned there because Herodotus didn’t spend nearly enough time on him.
I read this book thinking about Alyssa Martin’s Pythagoras cake bust. She owns The Martin Epicurean – and cake that looks like a face – how cool is that?
I read this book because I will pretty much read anything, but especially because I love science more than my student transcripts could possibly portray – mostly because I avoided science courses like the plague. I like the philosophies of science and concepts… I don’t care for the formulas and the math, but I’ll learn them ok if there isn’t any testing. Oh God, my test taking anxiety is insane… but reading up on it all, I love that. After all, it suits my passions:
“Science is the discipline that attempts to describe the reality of the world around us, including the nature of living organisms, by rational means.” – Dr. Herbert A. Hauptman, Nobel Laureate
This one is a keeper. I checked it out from the library, but I plan to purchase it when it comes time for kiddo to read it. It’s an educational must-have.
Hope and Mirrors (Clans of the Alphane Moon Review Part Two)
“[…] we’ve lost her. Nobody can claim this woman for long. It’s just not in her nature, in her biology.”
“She, as well as he, as well as everyone […] struggled for balance, for insight; it was a natural tendency for living creatures. Hope always existed […]”
That line hit me like a train. I loved it. I loved the twist in Mary’s character. I love the terrible beginning and the hopeful ending in the midst of far worse circumstances. I just got a tattoo last month “I am half agony, half hope.” Hope in the midst of agony and agony that leads to hope is my mantra. I loved this moment of humanity so brilliantly expressed. The fact that I have a Jane Austen tattoo and binge read Philip K. Dick may not seem like two cohesive characteristics to other readers, but to me few other writers have grasped humanity so cleverly.
I have loved all of PKD’s work, but Clans of the Alphane Moon (four Philip K. Dick books into my discovery) just might be my favorite so far.
I said so to a fellow Dick fan and he said, “Funny, that’s one of his most disliked books.”
“Really? Why?”
“I don’t know. From what I’ve read a lot of people criticize the plot.”
I looked into this, of course.
“Just as Phil breaks the rules of reality, he also breaks any and all literary rules at the same time. The result is a Dick vision presented in an inconsistent story that is not fully developed.” – Jason Koornick, http://www.philipkdickfans.com/literary-criticism/reviews/review-by-jason-koornick-clans-of-the-alphane-moon-1964/
I’m not a plot person. I don’t care about plots. I like well written people and unusual circumstances. I like to learn something new about the world around me and myself. I could care less whether or not the story moved the way it *should* have. Maybe this is why I like Dick. He doesn’t seem to give a rats ass about the rules of writing. He just tells his stories.
Koornick proves this bookish faw of mine when he writes, “Let us not forget that the most memorable moments of many of PKD’s best (and worst) novels are the “situations” rather than the characters or plot development. It is on this level that Clans of the Alphane Moon succeeds.”
If you’ve read my own published novella (nothing nearly as good or even in the same realm as any PKD story), you’ll see that plots are not my strong suit and that open ended ambiguous endings are my favorite. I have no problem leaving someone hanging and asking for a wee bit more. I’d rather be asked for more than be told, “Oh my gosh that story just wouldn’t end!” Even if that means I jump to a random conclusion without spoon feeding anyone. *SPOILER ALERT* So Mary and Chuck reconcile for no clear cut reason. That’s marriage. You don’t have to have a clear cut reason for making it work. You just do – even if you’ve been screaming bloody murder for weeks (or years) on end… you have a moment and remember what you’re there for… even if it’s just a vague inkling of a thought you can’t express.
I like the ironies and the exaggerations in this one. It mirrors my mind. Constant ironies. Always a hyperbole (or a thousand). It may not be everyone’s favorite – it wasn’t even PKD’s favorite – but I like it a lot.
I think the most amusing thing about the novel, isn’t the novel itself but rather PKD’s own reaction to it:
“One night, after taking a great number of amphetamines, I sat up reading three novels of mine which I hadn’t read since the galleys: THE THREE STIGMATA OF PALMER ELDRITCH, CLANS OF THE ALPHANE MOON, and UBIK. Of the three, only UBIK struck me as having any worth. I genuinely enjoyed reading it. But STIGMATA merely puzzled me, especially the last scene & ending. CLANS had one good item: the robot-body programmed to attack Bunny Hentman’s rocket ship (along with everyone else intending to attack it but not doing so) — the robot attacking the ship all alone, and the people in the ship saying, puzzled, “Who’s out there attacking us?” Very funny, I thought… and then the horrible wonder came to me, saying, “But when I wrote it did I intend it to be funny?” I’ll assume I did.” [Selected Letters, Vol. 1, p. 294]
As soon as I finished reading, I handed my copy to the librarians to check in and re-shelve and pulled out Minority Report, which I read all at once. Although, if I had read the above quote first, I’d have grabbed UBIK. Solar Lottery, however, is next.
I Dare You (Clans of the Alphane Moon Review Part One)
On page 42 and I already teared up twice. #SciFi should not make me so emotional. #NerdProblems#ClansOfTheAlphaneMoon@philipkdick
Here I am still chronicling my emotional well being through Philip K. Dick novels. I’m torn between telling myself to shut up and stop being a drama queen and diving into a full on crisis regarding empathy and my constant struggle to have some. Sympathy is really my problem. I can put myself in someone else’s shoes just fine, embrace, feel what they feel and all that – so a struggle for empathy isn’t truly my issue. It’s sympathy I don’t have. I won’t pity others, I won’t feel sorry for your plights. I will consistently tell you to suck it up – I might also slap your ass and say “Go Team.”
The question is, should I pity and sympathize? I was always taught those things were the most condescending things you could feel for another person. But not feeling them seems to make me crass, blunt to the point of tactless, and generally unpleasant to those in my outer affiliations as well as my inner most circles.
“Tell me if I start to sound bitchy, because I don’t understand why ________ can’t get their shit together,” I told my Em over coffee. I know how they feel, I understand the issues, the struggle, and still I’ve been there and I survived and I’m not any good with my feelings… I just don’t think anyone anywhere holds the license to struggle more than another, so stop whining and figure it out. (Take note that I am completely aware that I am currently – and often – whining about this.)
“Ok, you’re being a bitch,” my faithful friend told me.
Fair enough.
Chuck’s wife, Mary, in Clans of the Alphane Moon is a terrible person. I relate to her more than anyone in any of his novels so far. So much so that when Chuck starts wanting to murder her, I started to tear up – again – because I see that she deserves his murderous thoughts, but I can’t see how she could possibly want anything different than what she wants. She’s unfair, unforgiving, horrible for sending her daughter away, terrible in almost every way. And I understand her.
In all this struggle for a empathetic balance, I am not sad that she might get murdered, I’m sad that she is the character I identify with. Am I a shrew? I don’t think so. But I could be. It’s probably silly for me to take Philip K. Dick novels so personally. Shouldn’t they be genre sci-fi candy to binge read? No. For some reason, every one is something I feel deeply about. I run on two speeds… psychotically passionate for no reason and completely numb.
I dare you to read Philip K. Dick and feel numb. I dare you.
Springtime Means Seed Time
We are kind of in love with our librarians at this “new” library branch. We loved our librarians at the old house, don’t get me wrong, but these ones have definitely weaseled their way into our hearts. Case and point – there’s this adorable seasonal bin one of the children’s librarians puts together, and of course, we find the *best* things there.
This week, it was Flip, Float, Fly
Of course, when we’re not reading and planting ourselves… we’re out and about playing in creeks and inspecting the forest.
