Strenuous

I meet a retired friend monthly for breakfast. He asked me this morning how I was doing and I said the first thing that came to my mind: it's been a strenuous month. A long-term friend passed away at the beginning of March, someone who had been part of my created family, godmother to my daughter. On Saturday we had the memorial for her; I did a reading which was a comfort as it gave me something to focus on but the experience wiped me for the weekend. I also sang in a concert Sunday, further draining me but also giving me some strength as performing always seems to do. More and more funerals, more and more conversations about loved ones with dementia. As my breakfast companion noted, we used to go to more baptisms than funerals but the balance shifted somewhere along the way. In my youth when I had the knees I was born with I ran long-distance for myself, never as part of a school team but steadily from my teenage years through my twenties. I was never fast but I did keep going. Th...

Remembrance of Nancy Tomkovick (for the Guest Book of her Funeral)

Nancy has been a part of my family's life for many decades now; we were honored to have her serve as our daughter's Godmother. As with all of her family I was privileged to meet, Nancy was bright and found joy in many different things; it is not surprising to me that she served as a librarian (media coordinator) given the breadth of her knowledge and interest and that she served children in the public schools, given that she had so much love to give that it went out beyond her family to the children of Alamance County. On a whim during mass once during the sharing of peace I flashed a Vulcan salute at her and she returned it without hesitation. Our lives are diminished with her passing but her memory is a blessing and I am grateful for it.

Stranded, Again

I have flown to conferences for thirty-some years. I have had to deal with a lot of flight cancellations. Sometimes they are my return flights and I am effectively stranded waiting for the next available flight.  This has happened to me again, in Houston, this weekend. We had some nasty weather here last night and as always it's not just the local weather that interferes with flight schedules since the planes are in constant use before I get to board them. With the government shutdown there are still issues with having too few air traffic controllers and from what I've read online that may apply here. I was raised to take pride in my country but we've had several decades of penny-pinching politicians that want to make sure that ordinary people don't have quality infrastructure, and the voters keep putting them into office so that's who we are as a country. Early on rebooking a canceled flight required a lot of phone calls, often dropped just when you thought you wer...

At Yet Another Conference

It hasn't actually started yet, that's a little later today. So what is this post about? 1) Traveling grows more difficult with age, primarily in terms of stamina. I do have two artificial knees so there's that as well. 2) I still love seeing new cities. I've been to Houston once before in 1979 for a couple of days on a university band tour so it's nice to be back without a clarinet. 3) I love seeing my tribe en masse. I've made mathematics my career for many many decades and my folk have their own culture and way of looking at life. I anticipate seeing old friends and discussing things without the usual how-do-I-translate-my-enthusiasm-for-an-outsider preoccupation. 4) I live a very structured, disciplined life, by choice. I am greedy in what I hope to accomplish in the time afforded me and never presume that I've got time to burn, knowing more and more folk who do not make it to my age. Work conferences are about the only time when I'm off the clock fo...

War

From when I was a small child I thought the founders of the US made a good decision in separating the power to declare war (Congress) from the power to execute war (the President as Commander-In-Chief). Who in their right mind would want one person, possibly unstable, to be able to commit a powerful nation to bloodshed? In my lifetime Congress has ceded this power to presidents. They let LBJ commit us to war in Vietnam. They gave George W. Bush carte blanche to do anything he wanted in the "fight against terrorism", a remarkably nebulous phrase to guide our acts of violence toward something constructive. Now, under Republican leadership, Congress just doesn't care any more. Trump and Israel have started bombing Iran. Bombing is cheap (our soldiers don't risk anything on the ground) in terms of public outcry and despite self-serving uses of the word "surgical" by the military regularly kill non-combatants. It is the knee-jerk belligerence we have come to expe...

State

Tonight is another State of the Union speech by President Trump.  I haven't listened to an SOTU for decades; I never really learn anything from the performance of all involved, with the one party standing up to applaud every sound bite.  Policies that are offered are often forgotten within a week. Aside from the speech it is appropriate for we citizens to consider the state of our union. Our president has publicly and repeatedly separated us into righteous states who support him and enemy states that need to be tamed. FEMA no longer considers every state worthy of support in times of need along these lines. What about our citizens? The economy is in the toilet after Trump's playing with tariffs like children's toys, pretending that they are not taxes and pisssing off our trade partners. Trump and his minions keep telling us both that 1) everything is great and 2) it's all Biden's fault. There are apparently people that believe these two opposing positions at the sam...

Evidence

One of the skills that Trump and his minions have is for distraction.  A while back there was the push to find evidence that he had used a racial slur starting with "N" used to hurt and harass people during his time on The Apprentice as if that were the only test if he was racist, despite his words and deeds specifically attacking people of color on a regular basis. Ignore this forest, see if you can spot a tree over there. It is that way with his pedophilia. Women have come forward accusing him of raping them (which is not new; over two dozen women have civil suits pending against him for sexual assault that he keeps managing not to have to deal with, the statute of limitations for criminal penalties for some unholy reason having expired) when they were underage, i.e., children. Raping children.  We keep going through the Epstein files (as we should) as if that, that will be the proof. Maybe it will. But maybe we could interview his accusers on the record and press charges b...

Voting

I voted in the primary this morning. There were a couple of choices to be made but in most of the races I knew who I wanted based on prior knowledge of the candidates. I had to show a photo ID to vote because of an election law. I have a photo ID because I am plugged into the mainstream; I have a driver's license. Many of the older residents of my state who might wish to vote do not. There are alternative ID's that are accepted and in different states there are filters in place; hunting licenses are good in Texas but not college ID's. To my knowledge no one from any government office is providing transport for the elderly to get them or offering to pay for the ID, which is a filter on folk who aren't very visible to the mainstream. One thing history has taught us is that when we increase the number of citizens who can vote politicians act differently. When only propertied white men could vote, government did not work very well for sharecroppers. When only men could vote...

Snow Days

My university closed its offices today and yesterday because of icy roads, so the title for this post is a misnomer. You really shouldn't trust what I write--- In my youth I would have probably driven in to work anyway, partly because I was a good driver used to driving in PA winters, and partly because if my car broke down I was a pretty good hiker and was always driving near something to walk to. Now I am older with artificial knees and know that I would probably need some assistance if my car broke down.  In this case wisdom and frailty seem to be opposite sides of the same coin. I taught my classes over Zoom and have met with several students that way, so the cost of the shutdown is less, both for me and for the university; if anything I think the accessibility of Zoom has made my university more cautious and more willing to close its campus. So: how the F are the Minnesotans able to protest ICE in full force with worse temperatures? I mean, wow. They decided they didn't wa...

Contents of Most Recent Email to NC Senators

 Sent to Senators Tillis and Budd of NC this morning: My uncle was a police detective in Philadelphia before he retired. He showed his face and his badge to all he talked to on the job; he gave his name and business card to the public he served. This is what law enforcement officials have done in this country as policy until now; what if anything has changed?   The violent thugs serving in ICE are not law enforcement. They do not protect and serve; they attack and refuse to identify themselves. They are a paramilitary force responsible only to President Trump and his minions, who reflexively desecrate the memory of their victims. All dishonor themselves daily, all lack integrity. Immigration is a serious issue. Using brutal thugs to deal with it is like using a chainsaw to remove an appendix. The appendix may need to come out but using a chainsaw is a silly solution that kills people. It is painful to think of all the children incarcerated by ICE. It is unthinkable to all...

Feeling Funny

I stopped feeling funny when Trump was first elected in November, 2016. While I knew that some folk really wanted him to destroy our nation's freedom, it felt as if he had conned (with so much help from Fox News and other Republican sources) many of our voters.  I still tell jokes and make folk laugh but there has been a difference inside. My wife has noticed it. In a week our classes will start for the Spring semester at my university and I will be more occupied. Right now images of ICE agents seizing a five-year old child to use as bait to seize his parents, of ICE agents holding cans of pepper spray close to observers' faces and firing point blank into their eyes to terrorize them into not filming the agents, of the ICE agent pointing his gun at Renee Good's head and killing her with no justification---only anger, well, they are running non-stop through my head. I know, I know, I know as a white male that police brutality is a fact of life for much of our country, that I...

ICE

Nothing has tested our values as a nation in the US as when we decide who can be a citizen. Aside from Native Americans all of us came from elsewhere. Often the decision as to who to bestow privileges upon has been explicitly racist, with the previous generation of immigrants wanting to exclude the next one. It is unpleasant and so we often delegate such decisions to our government and try not to think about it. A humane approach would be to identify who could benefit most from admission and become productive citizens, but bigotry has often triumphed. Social justice has been important to our children, making my wife and I quite proud. My son led pro-immigrant rallies in university and very early on pointed out to me the brutality of ICE during the first Trump administration. This time around ICE has been the defacto armed thugs suppressing freedoms of citizens and non-citizens alike. Masked and without badge or judicial warrant they have been terrorizing city after city, killing and in...

Attempted Coup Anniversary

Five years ago I watched in horror as the mob that Trump called to a rally obeyed him and attacked the Capitol, killing police officers, desecrating the building, while Trump withheld forces from dislodging them as they sought to kill Pelosi and Pence. Last November I watched in horror as voters reelected Trump knowing that he had attempted a coup on January 6, 2021.

New Year's Wish

2025 has had its joys and its horrors. My country has taken the lead in worsening the climate, has increased childhood measles, has ended the rule of law to the point where armed goons grab people off the street if they don't look white enough. Cuts in USAID funding have doomed thousands to die of starvation for no particular reason. Billionaires like Musk decimate the folk in our federal government who actually help people and then just walk away. And yet we resist. I was born in the early 60's, raised fundamentalist, taught about martyrs facing violence and death to stand for what was right. My folks pointed me to Christian martyrs in history while I followed the Freedom Riders  and  other civil rights activists who were doing this in real time. I heard Bernard Lafayette of the SNCC, a surviving Freedom Rider, speak once about how the only folk who made things better were in it for the long haul, and that every loss was an opportunity. I try to have that kind of hope, the ki...

Holiday Break

I have been teaching for 37 years now, and I go through many of the same things at the end of the Fall semester each year. There is relief at the completion of a significant task (teaching each of my classes) but there is a good deal of physical and mental weariness and aches. I could sleep for several days straight if not for my sleep disorder. By and large my mind is not very sharp and as an introvert I try to be pleasant with loved ones but am not outgoing at all. With age the feeling of being drained deepens in more and more ways. Of course this is when we have, almost every year, taken a road trip to visit birth families in the Northeast, a full day of driving each way, often involving winter weather far worse than what we are accustomed to in NC. I love my birth family members as well but as with my created family I am weary and not very outgoing. The conversation is rarely about me and my day-to-day life but rather about younger family members and family friends that I do not kn...

Car

It is strange to me remembering how many cars I have owned as I don't think of myself as being as old as I am.  I've moved on to my next one after losing my previous one to a deer collision and renting a car (paid for by my insurance). Because I have an hour commute I typically stow a good amount of gear that I may need during the day in my trunk. Because I often do road trips I stow things that I may need inside my car. While waiting to replace my car I felt the lack of those two storages; not so much that I needed them but more so that I am more materialistic than I like to think and draw security from these things. I do not enjoy shopping and technology has made it possible for me to scout what I want on the internet pretty freely before making a purchase at my own pace without having to interact with other human beings. I am an introvert and while I enjoy the company of others it does drain me. Once my insurance claim had cleared I shopped on Saturday for a commuter car, so...

Deer

We have a lot of deer in our area, both near our house and for the first part of my commute.  I first totaled a car hitting one in either 1999 or 2000, and have been very cautious since then about trying to find routes that had fewer of them.  I had a go-to route that seemed to minimize the number of them running across my path. 14 months ago I totaled my car striking the side of a car that had been abandoned on an inner lane on the interstate.  I've had car accidents, none my fault to the best of my knowledge, but I've had them. 17 days ago I struck one on this route that seemed safer. (It ran off so I don't know if it survived; I had time to stomp my brake and hit it at a slower speed.) My car still functioned (I could drive it; no warning lights on the dashboard; both front light bulbs still worked) but one headlight was shattered and the grill and hood took some damage. I filed the claim through my insurance company, had an appointment with a body shop, planned on get...

Collective

Something good happened this week; I was informed of it yesterday when a colleague forwarded an email to me announcing it.  The announcement had to do with our university administration committing resources to something that needed doing; the fact that it had not been done had threatened the safety and work environment of dozens of my colleagues. I was clueless about it until in my job as ombudsperson I heard about it from multiple individuals. 95% of my job as ombudsperson (roughly) is focused on the individuals who come to me, brainstorming about their options and weighing the advantages and disadvantages of each. I've been around my university for over 36 years so I've picked up some knowledge of our system and as a mathematician I have a lot of training and experience in problem-solving. I'm not bad at counseling stressed individuals; professional development at ombuds meetings has helped me a lot with that. 5% of my job as ombudsperson (roughly) is managing upward. The...

Funny

I've been fond of Monty Python since I was a teenager.  Looking back now at their television and film performances you can see the tropes that they now express regret about (stereotyping women, people of color) and that is off-putting. At the same time their sense of humor was incredibly subversive and many of the concepts are still stunning to folk who experience them from scratch. I feel that way about much of the alternative humor I enjoyed in the 70's: Firesign Theatre, Bob and Ray, and so on. Mixed bag but much of life is that way. I have read many of the writings of the members of Monty Python; they were all Oxbridge graduates and very literate. One point that several of them have made repeatedly has changed how I think of teaching. When they were first cresting in fame and popularity, Monty Python came to America and did many live shows. Occasionally they would do two performances, a matinee and an evening performance, with exactly the same material. One show would bomb,...

Public versus Private

I have never served in the military, although family members have, as well as the paramilitary (police). I have been in academia most of my adult life. Because I have an interest in systems and how to make them work better I was drawn early in my career to committee work, and along the way I would have disagreements with folk. As long as I felt comfortable that we shared the same goals and values I have not been bothered much by disagreements over means, and I have frequently learned from them when I listened to someone who was more right than myself. Although I have done a fair amount of public speaking, primarily at faculty meetings as chair of Academic Council one year and chair of our University Curriculum Committee for a decade or so, I have rarely sought to resolve disagreements publicly. My experience, in person and in what I have picked up from listening to others, is that folk are much more defensive in front of a crowd (I know that I have been) and more likely to dig in on th...

Redemption

Our daughter loves the TV show Leverage, and I've enjoyed it when I've seen it; we were just talking about it over breakfast. It's a redemption tale (about a talented group of lawbreakers who decide to stop powerful people from hurting powerless people), and I've always been fond of those---LA Confidential is probably my favorite. In any event, one of the principles of Leverage is that redemption is ongoing. One of the characters discusses that as a key part of Judaism; as an ignorant Christian I can't speak to that but it resonates with me.  Many folk think of redemption in terms of an apology, which is an instant in time and often does not involve much sacrifice or in any way make right the injury caused by the sin. Easy things don't really count for much in the big scheme. Redemption attempts to make right the injured party or parties' damage but it also attempts to make right the sinner. That in particular is why it is ongoing, because people don't c...

Symbols

I grew up with a lot of symbols around me; most people do. I had a Statue of Liberty pencil sharpener; I had a miniature Liberty Bell.  Most of the symbols weren't physical objects that I owned but were large things that belonged to the nation. The Lincoln Memorial was always my favorite, in contrast to the Washington monument. The Lincoln Memorial gave priority to Lincoln's words about freedom, particularly freedom for all. The Washington monument is a big phallic symbol. Washington deserved better in my opinion but it's hard to be build a memorial to someone who kept despair at bay for many years of fighting losing battles against the British until his war of attrition paid off and they gave up. How do you build a memorial to someone who refused to be crowned king and then walked away from the presidency in order to ensure that liberty would outlast him? The White House is a symbol; its nickname is the People's House. It is a weird mix of really important offices and ...

Accountability

Mathematics as a discipline teaches accountability. Every claim, whether it be a computation result or a statement (theorem) about how things work is accountable. We teach this accountability developmentally, with lower expectations at the beginning, and sometimes folk who study mathematics casually don't understand this. In my multivariable calculus classes, which I teach most frequently, I usually phrase my expectations as "give me a reason to believe your answer", citing my time working at an investment bank where my recommendations had financial repercussions and my supervisor never took my word for anything. In higher-level mathematics classes such as Abstract Algebra or Analysis I can be more explicit: these are the things we all agree to assume, these are the proof techniques which we understand; can you make an argument that convinces the community who have accepted those axioms and rules of inference that what you claim is true? We work hard to remove the ego fro...

Oversight

Attorney General Pam Bondi appeared before a Senate oversight committee yesterday and refused to answer questions she didn't like from the Democrats, casually accusing them of crimes without offering any proof.  It started me thinking about oversight. The US was founded in opposition to the notion of any leader being free of oversight; our three branches of government were set up to check the power of each other. It is failing now because all three of the branches are under the control of a party or politicians who have betrayed their oaths to serve the constitution. In my own professional life I have had oversight the entire time. As a faculty member I have often reported to a department chair; when serving as department chair I have reported to a dean or associate dean; when serving in our shared governance system, chairing a Task Force, the Curriculum Committee, and Academic Council I have had oversight from Academic Council. Oversight can be frustrating but almost all of my ove...

Family Weekend

Our university like many others offers programming for families who visit about a month into the Fall term. There are events intended to give families a feel for what the university provides; part of that has always included a time-slot on Saturday morning to meet with the faculty. There are two ways these meetings can go. During my first decade or so family members pressed for details about their student's class attendance, participation, grades, etc. At some point the university put its foot down (possibly before federal privacy laws required it) and said that those kinds of conversations were off-limits. It became easier to refuse those questions with the university making it policy and explaining it in opening ceremonies for the families. The other way, the fun way, is for us to give some sense of our classes to the families. I like what I teach and I like teaching it, so the word fun is appropriate. After all these decades I don't get tongue-tied and can go on at length ab...

Questions During Exams

Exams are stressful for students. This plays out in all kinds of ways. Compassionate proctors try to help rather than ridicule. I proctor my own exams as do most of my colleagues except for instances of illness, family emergencies, etc. I have a lot of students come up to ask questions during the exams. Occasionally an exam question really is worded poorly, although as I grow in experience this happens less frequently. Most often my answers fall into two categories: repeating something that I have said when handing out the exams (thus missing latecomers) or requests to help answer a question.  In both cases it is my responsibility to treat the question seriously and with respect, even if, as in the latter case, my answer is "I'm sorry but I can't answer that right now." Many years ago a number of my colleagues and I attended a talk at a conference wherein the speaker addressed the fact that most students by the time they reach us in university classes have been humili...

Mergers

My university announced plans earlier this week to merge with another university in a different part of our state. I've been there, it's nice although less than half as big as we are. There are tons of issues to work out before it is approved but our community is trying to take in what our trustees worked on in secret over the summer. As with most colleges and universities we've seen for a while the demographics coming----the continual increase in students of age to go to university is finally backing off. Coming after the damage that the COVID pandemic did, a lot of schools are hurting financially. We are in a good position:  no unnecessary hiring, budgets cut, but no layoffs. The school we are merging with took a bad hit from the pandemic, and are trustees feel expanding into this part of the state and pooling our risk (both of us are heavily dependent on tuition) will keep us sound going into the next century. Right now all of the discussion has been about finances, lega...

Charlie Kirk Assassination

Charlie Kirk made a career of bigotry and encouraging the targeting of people that he didn't like. He had many followers and in that sense he was very successful. He was assassinated this past week in the sense that he was killed (apparently) because the shooter thought that his views weren't extreme enough. I don't care to add much to the vast amount of reactions to this killing other than two points, one logistical and one deep from my heart. First: early news about assassinations is almost always wrong. Period. That is how it works. Consumers of information want that information immediately and many people who don't care about the truth are willing to make up stories that they think will satisfy that hunger, for (sick) fun and profit. If you care about the truth it is a right and moral act to refuse to consume inaccurate information about such events but to wait until there has been time for law enforcement and journalists to uncover the truth. Nothing, repeat, nothi...

Behavior Modification

As a teacher a large part of my job involves behavior modification, rewarding useful study habits and not rewarding useless ones. We don't talk about it much but I am aware how much I try to modify the behavior of my colleagues and superiors, and how they try to do the same with me. This is not evil; it is how we advance our priorities.  In academia we (truly or otherwise) tell ourselves that we achieve this through making arguments with merit based on research. We are also part of an organization with superiors and occasionally subordinates, where we attempt to modify behavior, nominally in support of the institution's mission. We are human and all fall short of the ideal. I am often wrong but having nothing else to work with I base my goals on my sense of what's right in attempting to modify the behavior of others. Every now and then I run into a colleague who does not think in these terms. They tend to be less successful. I think the key is to face it head on as part of ...

Handling Dishonesty

I have found it useful to act as if I believe what I am being told by people who are part of my life. I don't extend this to sales people, politicians, etc.; I am referring to folk who I will interact with over time and whose behavior I am capable of modifying. I do not always believe what I am being told by this group of people. That sounds cynical and I find cynicism to be incredibly lazy as an approach to life so I hope that my judgment is more than automatic rejection. I know that my memory of what I have said and done often improves with age as a fine wine or cheese does. Perceptions, particularly of one's own actions, are very doubtfully completely accurate in the aggregate. I aim to score in the high 90's in my life but I'm not the one who can do the grading. Sometimes there is evidence of intentional dishonesty. I catch students cheating from time to time, and denials fail in the face of clear evidence.  In every other context in my life strong evidence of inten...

Groups

There are very few lives and even fewer that are satisfying that don't place a person in the context of a group, whether it be work, family, friends, etc.  My childhood had a great deal of stability and so the first group I was conscious of was my birth family. Later friends in the neighborhood and school classes extended that. Many of us assimilate what it means to be a part of a group at an early age, with adjustments as our social networks evolve in the teen years and then the workforce, etc.  I played in a school soccer team for two years but I never really considered that to be formative; I wasn't very good at it and so I avoided a lot of relationships on the team out of shame at my lack of coordination. On the other hand, 56 years ago, I started performing in music ensembles. While many males (the expectations are different for the genders despite the prevalence of excellent female athletes) do and are expected to learn group dynamics in athletic contexts, it was musical...

Adrenaline

Yesterday was the first day of classes for the Fall Term at my university. I've been doing this for a long time but I am always surprised by the rush of adrenaline that comes with the start of classes. I enjoy teaching and the sight of students in the classroom directly triggers the accumulated feelings I've amassed.

Planning Week

Long before I arrived at my university in 1988, the week before classes was set aside as Planning Week for returning faculty. (Staff planned all summer long.) I've had various leadership roles over the decades and more often than not I was responsible for leading one or more meetings during this week.  My routine for leading a meeting was to remind people of the date with some lead time and ask for suggestions for the agenda with a firm deadline, write the agenda and distribute it, and annotate the agenda with specific goals that I did not so much hide as leave out to keep the agenda from being too verbose. At the meeting I would take notes of the discussion on my copy of the agenda for follow-up details, try to make sure that everyone was participating, nip in the bud separate conversations among subsets of the group that excluded others, point out when the group was repeating itself, and articulate draft consensuses (consensi?) for the group to revise or object to. While it was i...

Manipulation Under Anesthesia (Part II, Continued)

The procedure went well as far as I can tell. My knee was and is a bit tender; icing helped but I did intensive PT this morning (part evaluation) and I'm feeling it now that I'm in my office. My physical therapist suggest six more weeks of PT once a week, and that makes sense; I could bend more this morning for having had the procedure but there's still room for improvement. I struggle, again, with the process of general anesthesia. For all my failings I have been able to rely on being observant and having a good memory for what I bear witness to. General anesthesia goes directly against that: I have experiences and at least in the beginning I converse with people with no memory afterward. There was a period of time when I co-chaired a university task force on alcohol use, misuse, abuse. That's a story for another post. But there was significant overlap between our work with alcohol and the incidence of regretted sexual experiences, a phrase which I've learned cover...

Manipulation Under Anesthesia, Part II

My right knee was replaced on May 22. I have had physical therapy regularly in the intervening (nearly) twelve weeks. I have recovered most of my flexibility but not as much as I and my health care team want. The most visible symptom is that when I walk down stairs my right foot catches regularly on the step, my knee not bending enough to avoid it. Less visibly I am aware of the small (five or ten degrees) deficit in flexibility whenever I walk. When my left knee was replaced in 2021 and I was at a similar stage I had a procedure known as Manipulation Under Anesthesia performed as an outpatient procedure. I was given a general anesthetic and the surgeon bent my knee enough to rip the scar tissue. I am scheduled to have the same procedure first thing tomorrow morning. While there are no guarantees about tomorrow, four years ago the MUA worked perfectly. I had no pain after the procedure (the scar tissue not having a lot of nerve tissue) and my knee acquired the necessary flexibility. It...

MathFest 2025

I've spent a half week in Sacramento attending MathFest, an annual meeting of the Mathematical Association of America. I joined the MAA in 1978; I was a high school student taking upper level math courses at nearby Ursinus College, and one of the department members, John Shuck, taught most of my classes. I still consider him to be one of my best math instructors, finding ways to explain and motivate difficult mathematics concepts. He was an MAA member and invited me to use one of Ursinus's student memberships. I continued when I went on to university myself and now have been a member for 47 years. Hard to believe. Side note: I ran into Shuck at a math conference years later and had the opportunity to thank him for the help he gave me at the start of my career. He remembered me. Sometimes life's like that. The MAA focuses on faculty and students, primarily at the undergraduate level but also at the graduate level. I have found regional and national service in the MAA to be i...

Sacramento

I arrived in Sacramento today for MathFest.  The name MathFest always feels a bit inward-facing to me---only my tribe seems to find math festive. The conference hasn't started yet; traveling three time zones I wanted to arrive before things started to allow for travel mishaps; sure enough my first of two flights today was delayed enough to make connecting to the second flight impossible. Big up's to the Delta phone app; it offered me alternatives and I found one with a different connecting city that had more of a layover (I had been nervous for the original layover being too short, which it turned out to be). I did arrive quite early though. Second, big up's to Hyatt for letting me have a room at noon when check-in time is 4 PM. In times past when this has occurred I have checked luggage and wandered a bit until my room was ready but this is much nicer. I am a bit wearied, having started my day at 3:00 AM EDT (early and paranoid about there being flight problems, said paran...

Beach Trip

My son flew in from Denver on Saturday and it's been wonderful having him around. My family (wife, son, and daughter) went to a beach trip after a few days in Delaware with my sister-in-law and nephew. I have a lot of pre-cancerous cells on my face that get scraped off once a year (I think my dermatologist is building a mask of my face) and I do not go to sunny locales any more.  My family took beach trips once a year to the Jersey shore as I was growing up in Southeastern Pennsylvania for many years, then switched to the North Carolina beach. I enjoyed riding the waves with a raft but moderately so. I did not enjoy the heat and sun so much. I enjoyed the boardwalk stores and pizza places in both locations but the enjoyment faded with each passing year. I brought books and whenever I could holed up by myself (as an introvert) and read. My family was prim in many ways; no alcohol (we have alcoholic relatives and that pained my parents) and not much partying. Insofar as my sister enj...

Epstein

I have many reasons to despise Donald Trump. As someone who lived in the Northeast for a couple of decades prior to 1988, he was regularly in my media feed in the 1980's, as a promoter who spent all of his time telling other people how great he was. I have more reasons than his being obnoxious: his refusal to pay the electricians and other workers who renovated his Atlantic City casinos unless they settled for 10 cents on the dollar (threatening to bleed them dry in court with his army of lawyers if they sued); his scam university; his sadism during his first term; his attempted coup on January 6, 2021; his treason with documents stored in Mar-a-Lago; his much more efficient sadism in his second term. It's a long list that he adds to daily. But, here is the trigger when I hear his voice: I would never want him alone in a room with my daughter. It's patronizing---she can defend herself, I know. But when he owned Miss Teen USA he bragged about going into the dressing rooms to...

Advocating for One Less Freedom

Our politics are broken but I dream of a day when free speech has one more restriction beyond yelling fire in a crowded room or claiming to want to kill the president. We need to stop people (particularly in politics or the media) from using the concept of average (or as we say in the math business, mean). The mean is useful when working with various probability distributions, i.e., in restricted technical settings. In common situations it is almost always misleading. If I am teaching a class and Bill Gates walks in, our mean wealth goes up by many powers of ten. Without mentioning Gates's entrance the mean is entirely misleading. It is often used by politicians and pundits to intentionally mislead about similar situations such as tax cuts that go primarily to the ultra-rich. The median is a far better measure. If you sort the data it is the middle value. If Bill Gates walks into my classroom the median wealth would shift by a couple of bucks. The mean is the average of a set of da...

Sadly Distracted

It's been a rough few weeks of news. ICE continues to act without check. Florida governor Ron DeSantis is showing off his new cages for immigrants to MAGA sadism tourists. Primarily our Republican legislators have agreed to take money from helping the needy and given it to the wealthiest at Trump's behest.  As is often the case NC Representative Virginia Foxx summarizes a lot of the MAGA hatred, throwing a fit when Representative Maxwell of Tennessee pointed out how fundamentally anti-Christian her actions are in demonizing immigrants.   To my knowledge none of those leading us into savagery are of Native American heritage and seem not to pause at all to be grateful that there ancestors were treated better. Not giving up, but it's been a rough few weeks trying to remain hopeful.

Driving

Just a quick note. Even though I have had my right knee replaced five weeks ago driving seems to be working out. I do not feel pain using the pedals; the main difficulty is getting in and out of the car.

Status Report

It has been 27 days since my right knee was replaced. I've had some good milestones---transitioning from walker to cane to doing without my cane. My sleep is beginning to improve (with the dull ache of my leg still hurting but not quite as much) and so I have started weaning myself from narcotics. Once they are clear of my system my wife will take me to a parking lot and we'll see if I can drive yet given my right leg is my driving leg. Once we are satisfied she will ride shotgun with me for a while before I drive solo. My work commute is an hour long each way so that is a ways off driving solo. One low point:  a week ago my blood sugar dropped quite a bit and I was incoherent. My wife called an ambulance and I was taken to a nearby ER to bring it back up in a controlled fashion.  No episodes since then, thankfully. My pain medications had killed my appetite---I lost 25 pounds in three weeks---but I had not stopped my diabetes medication and had failed to check my blood sugar ...

Whole Lot of Reading

I had my right knee replaced on Thursday, May 22. My activities since then have been very limited, doing PT, elevating my leg, taking painkillers. I have been catching up on my reading a bit. In anticipation of my downtime I have accumulated a number of e-books in my Kindle account that I have been rotating through as my whim takes me. Here are some short descriptions of my current books: The African Trilogy by Chinua Achebe.  Many years ago, upon the recommendation of others, I used Things Fall Apart as one of my readings when teaching our university's first-year Global Experiences seminar. It covered a lot of good themes and not just the prominent colonialism. Recently I saw a reference to the fact that Things Fall Apart was only the first book in a chronological trilogy and have enjoyed rereading it prior to getting to the next two books. The Elements of Journalism by Bill Kovach and Tom Rosenstiel. It has been many years since I last taught our university's first-year Globa...
