I learned last week that the baby Panda born in the National Zoo only recently has died, when it was less than one week old. I read that the mother Panda let out an “unusual honking sound” when her baby would not wake up.  Although we are of two different mammalian species, I could i

Although less common than in the past, I sometimes still run into students who are convinced they cannot learn math. Some of these students are women old enough to be my mother, who grew up in the days when it was assumed that math was for men and not for women. I recall one woman sitting in my office almost in tears, telling me that she had never been able to do math. I pointed out that she had six children, including a specials need son, and told her that any woman who could raise six children most definitely knew how to do math. I do know, however, that my own image of myself as a non-athlete is similar to her view of herself as not mathematical, and have to conclude that our perceptions of our skills in such subjects are in many ways dependent on the time in which we grew up. I was lucky enough to have a teacher in second grade that saw that I was good in math, but never lucky enough to have a mentor who encouraged me to be athletic. My daughter is lucky to have people who do.

I was just finishing a proof we would be discussing in my Calculus III class this past Tuesday when I heard the bagpipes.

One topic I really enjoyed in my high school art class was perspective, the artistic technique used to create the illusion of depth in a picture. This is a concept that is also studied in Geometry, and it is a concept that I found myself thinking of this past week as I laughed at the fact that my daughter seems to be at a point in her life where she thinks that the world revolves around her. This perspecticve is at least partially caused by the nurturing neighborhood that we live in, where everyone’s child is important and neighbors are people to not only live next door to but to also socialize with us and support us as we live our lives on a set of a few streets way off the beaten path.

In statistics, we talk about a “population” as being everyone that could possibly be included in a study, such as everyone who lives in New York City. In contrast, we talk about a “sample” as being a subset of a population, as, for example, all people in New York with a last name beginning with “L”.

In some of our classes that fulfill the math requirement for the core curriculum, we occasionally teach sections involving logic, asking questions such as, “if we say ‘if A, then B’, does that mean that ‘if B, then A’?” I found myself thinking of these questions as I was delighted at the signs that sprung up on campus this week directing new students to various events on campus.

There is a theorem in Economics known as “Arrow’s Impossibility Theorem” that, as proposed by the Nobel Prize winning economist Kenneth Arrow, discusses the impossibility of coming to a conclusion that completely satisfies the preferences of a multiple of voters. I thought of this theorem recently when I attended the memorial service for a former colleague who had done what I thought was impossible. As plans for this service came together, I learned that he did not just die suddenly, as the announcement of his death informed us. In fact, he had actually taken his own life. I found myself at a complete loss in explaining what happened to him to my daughter, who, until now, has been relatively sheltered from this dark reality.

I study the workings of organizations whose main purpose is not just to earn money, but to do something else. Just what that “something else” is has not completely been determined, and so the “objective function” of the nonprofit organization remains a “holy grail” for my sub-sub field that many continue to search for. I must admit that I am among those searching for this elusive model.

There is a classic problem from Algebra that torments many a math student. If one driver leaves New York going 150 miles an hour, and another leaves Chicago going 200 miles an hour, where do they meet? (the answer- jail; they both were arrested for speeding!) Another classic problem haunts Calculus students, in which the volume created by revolving a function around a line is calculated. It is that latter problem that I was reminded of as I watched daughter, who would soon be too big to be riding such a small animal, ride a pony last weekend.

There is a concept in statistics called “expected value.” This is the expected outcome of any situation that involves probability, and is found by multiplying the possible outcomes by the probability that each will occur and then adding these products together. Expected value calculations are why it is generally thought that one should not play the lottery, as some claim that the lottery is a “tax on people who did not do well in math
