Reef Madness 4: Alexander Agassiz Comes of Age
Of the year that Alexander lived in Freiburg, so few facts survive that it’s hard to know what to make of them. He arrived sometime in the second half of 1847, not yet twelve years old, to find his mother living “in most straitened circumstances,” as George Agassiz would later put it, in a tiny apartment near the Schwaben Tour, a tower over one of the city gates.
Apparently never robust, Cécile was now ailing. Still, Cécile reportedly loved Freiburg, an extraordinarily charming town that was then perhaps at its most alluring. “She greatly loved the quaint old walled cathedral town and its beautiful surroundings,” her grandson George relates from the distance of two generations and an ocean, and “although now an invalid, she was still able to take short excursions into the country,” where she would draw the flowers brought to her by her daughters or the beetles, caterpillars, and butterflies captured by Alex. “The Freiburg winter,” he continues,
with its bracing and sunny air, was an especially happy time for the children. Alexander now became a proficient skater, an art in which as a young man he excelled…. The boy and his mother spent many happy hours, while she sat in one of the high-backed sleds of that region, which he skillfully guided through the gay crowd of all ages who glided gracefully over the ice.
This is hard to credit. At the age of twelve, having spent the previous 18 months in limbo as his parents parted ways, by all reports sensitive and prone to melancholy anyway, Alex probably felt something short of “especially happy” that winter. The transition from the window-smashing youth to the smiling skater seems forced. Possibly Alex himself held to that memory and passed it down because his skating supplied a pleasure rare in what otherwise must have been a dark winter.
Other tidbits refer to botanical outings with his Uncle Alexander, apparently a generous and kind man, and consultations with Braun’s colleague the zoologist Carl von Sieblold, who helped Alex classify his bugs, extracting as a fee an occasional choice beetle. These stimulations, along with being reunited with his mother and sisters, must have brought Alex some lift, and perhaps he indeed felt some of the sunny optimism that the relayed skating memory suggests.
Yet the winter was grim enough to spoil forever his love of music — a significant loss, given his mother’s cultivation of his taste for it. His bane that winter, he later recalled, was his violin tutelage. He had never loved the instrument, and he took his lessons now in the early morning in a cathedral so cold, he later told his children, that he could scarcely hold his bow. His teacher, perhaps frustrated with Alex’s lack of enthusiasm, would correct his worst mistakes by rapping him on the knuckles with his bow.

He excelled in all sciences and in math, having more luck than most in following Peirce's lectures. Yet while he spoke five languages, he showed little interest in formally studying any of them, and he assiduously avoided philosophy.

In a recent 50-minute pre-algebra class, Evans packed in half a dozen exercises to instill a math lesson on “order of operations.” Evans also urged her students to think about order — or disorder — in other areas of their lives.

The Order of Operations Explained: Intro and Mnemonics | MathFour
Inspired by Jimmie’s daughter’s order of operations mnemonic , I’m finally getting to the series I’ve thought about for a while.
The Order of Operations (OoO for short) is used everywhere in mathematics because it encompasses many of the foundational rules that we’ve agreed to follow.
Alas, students have been given the cheap and dirty version of it for years. “Here, memorize this thing about your Dear Aunt Sally!” What the heck?!
There are subtleties in the Order of Operations that every person over the age of seven should know.
The series begins today.The order of operations is a set of rules – like the drivers’ handbook for math. If everyone follows the rules, we’ll all be safe. But if someone makes a bad turn, we could be looking at a crash.
But the Order of Operations is only a set of rules for arithmetic! It isn’t even the best practice when it comes to expressions involving a variable like x . I’ll cover what I mean in this weekly series.
Here are the proposed articles:
Intro and mnemonics Parenthesis Exponents, Multiplication and Addition How exponents work with parenthesis Multiplication and division Addition and subtraction and conclusions Mnemonics for PEMDASWell, there’s one: PEMDAS (pronounced just like it looks). That’s what the cool kids in high school always said. It was the same kids who said “ soh-cah-toa ” – which I thought sounded really goofy.
And then there’s “Please Excuse My Dear Aunt Sally.” And of course, Jimmie’s daughter’s “Piranhas Eat Mostly Decayed Antelope Skin”.
What’s your way to remember it?
I don’t use a mnemonic. I point out that addition and subtraction are low level (basic) operations taught first in school. Multiplication and division are built on the concept of repeated addition, so they are higher level operations and are taught after + and -. Exponentiation, and its inverse taking roots, are built on repeated addition. They are the highest level operations.
The rule is to do higher level operations first. Use parentheses whenever your intention is to deviate from this rule.
the order of operations is a general rule for math, not just algebra ;)
Commercial for Dave and Busters. Ad exec must have skipped math class when they discussed 'order of operations' 
Order of Operations, people!!!! You do Multiplication BEFORE Addition and Subtraction! It's MIDDLE SCHOOL MATH, people!!!!!!
Whoever put math problems on Facebook polls is making me sad, as it's showing me how many friends of mine fail at order of operations.
Have people really forgot the order of operations? 1+1+1+1+1+1*0 is not zero (it's 5 btw). Or did I miss the news (it's plausible)? Math Order Of Operations - Bookshelf
