The Enchantress ofNumbers The curious tale of the worlds first computer programmer. Today I stray a little from the ordinary literary and educational news updates, after coming across a nod to an exceptional woman I couldnt pass the day without commemorating, not only for her role in mathematics, but also for her role as a woman in mathematics, far ahead of her time. I hope that her story inspires women in the sciences, or indeed anyone who perseveres to think beyond the capabilities of modern technology. Sadly Im usually behind the times on Googles artistic and quirky depictions of special days via their homepage. But today, gmail just happened to crash, sending me to the Google homepage where I saw the below image: I was curious. Who was this woman in 19th century garb, scribbling mathematical functions with quill and ink? And so, by way of technological error, I learned of Ada Lovelace, the worlds first computer programmer. Ada Lovelace was born on December 10th, 1815, to the poet Lord Byron and his wife Anna Isabella Byron. She had a miserable childhood, considered a disappointment from birth for not having been born a boy. Ada was abandoned by her father before she was a month old and  resultantly  never knew him, as he died abroad when she was eight. Meanwhile her mother chose to keep little connection with her, possibly because young Ada reminded her of her devious husband, with whom the Baroness had an acrimonious divorce. So Ada was raised by elderly relatives and relegated to a life of suspicious observation via her mothers friends, dubbed the Furies. Fortunately for us, though, she was also subject to a life of educationintended to squash any deviation she might have inherited from her fatherand took a keen interest in mathematics from a young age. Around the age of seventeen, Adas special abilities became clear to her tutors, all famed in mathematics in their own right. The noted mathematician Augustus de Morgan even reported of Ada to her mother that she seemed destined to become, an original mathematical investigator, perhaps of first-rate eminence. Meanwhile another one of Adas instructors and friends, Mary Somerville, introduced her to Charles Babbage, future inventor of the worlds first computer. Ada was not yet eighteen at the time. Babbage and Ada thus began a friendship that produced their academic collaboration on the formers Analytical Engine. In 1843, Ada translated Italian mathematician Luigi Meanabreas explanation of the machine, complete with her own set of notes and conclusions (which were actually longer than Menabreas). In her depiction of the Analytical Engine, Ada imagined its potential as being greater than simple number crunching, something not even Babbage indulged in. She wrote: [The Analytical Engine] might act upon other things besides number, were objects found whose mutual fundamental relations could be expressed by those of the abstract science of operations, and which should be also susceptible of adaptations to the action of the operating notation and mechanism of the engine Supposing, for instance, that the fundamental relations of pitched sounds in the science of harmony and of musical composition were susceptible of such expression and adaptations, the engine might compose elaborate and scientific pieces of music of any degree of complexity or extent. Along with these forward-thinking notes, Ada wrote a computation of Bernoulli numbers for the Analytical Engine (below). It is this part of her thesis, Note G, that is universally considered to be the worlds first computer program, making Ada correspondingly its first programmer.

That means that on this day, as you browse the Internet in search of Google poetry, GIFs, or the Ikea Monkey, you have Miss Ada Lovelace to thank for her place in imagining the capability of computers to change our lives in the myriad of ways they have today. Ada was such an interesting woman, there is only so much of her life I could include in this post. I highly recommend her Wikipedia entry as an overview of her amazing achievements and somewhat scandalous personal affairs. In her mere thirty-six years, Ada gave us much to appreciate and stands as a prime example of the role women have played in science and technology, though they are often overlooked. She truly lived up to Charles Babbages nickname for her, The Enchantress of Numbers: Forget this world and all its troubles and if possible its multitudinous Charlatans  Ã¢â‚¬â€œ every thing in short but the Enchantress of Numbers.

It comes with an activity to help students write their very own programs and is recommended for Grades 4-8.

Supervise vs. Monitor

Supervise vs. Monitor Supervise vs. Monitor Supervise vs. Monitor By Maeve Maddox A reader wants to know if there’s a difference between the verbs supervise and monitor. Both are synonyms for the act of overseeing the execution of a task or activity. Some speakers use them interchangeably, but they do differ in connotation. Supervise implies more interaction than monitor. Supervisors have the responsibility of informing and directing, while monitors observe without instructing. A person who supervises children is expected to step in if they behave contrary to expectations; a person or machine engaged in monitoring an activity is not generally expected to deal directly with a problem, but to alert a person in charge. The noun form for supervise is supervisor; monitor serves as noun as well as verb. A supervisor is always human; a monitor may be a human being or a machine. Monitor comes from Latin monere, â€Å"to warn.† It’s the monitor’s job to warn someone that some activity is not proceeding according to plan. You might monitor your utility bills by keeping track of the monthly increases and decreases. The Yankees also will monitor what the Brewers do with Rickie Weeks, who could be beaten out at second base by Scooter Gennett. Just asking a child to monitor their own behavior will increase the behavior that you want and reduce the behavior you do not want to see. Sometimes a monitor may be expected to act, but only in an extreme situation requiring immediate attention. Police expected to monitor Rizzuto funeral visitation closely Another noun for the person who oversees the work of others is overseer, a word which can bear a negative connotation. Historically, an overseer was in charge of slaves or, in Australia, a band of convicts. In modern Australian usage, an overseer is the manager of a sheep station or other rural property. In American usage, an Overseer is a member of a university governing board, or a religious leader. In general American usage, however, overseer is still strongly associated with slavery; think Jonas Wilkerson in Gone With the Wind. Want to improve your English in five minutes a day?
