While many schools are back to in-person classes, there are still many courses being offered online due to the pandemic. In fact, a number of schools had to revert to online classes after severe COVID outbreak on campus. So online lessons are not going away anytime soon for traditional in-person schools.
At the start of the Fall 2021 semester, during many of the meetings I attended with faculty members from my department and other departments, one of the most common "complaints" that I hear was how to get the students to turn on their camera. The school has made it abundantly clear that we cannot force the students to do that, and that turning on their cameras was something voluntary.
Still, many faculty members were having a hard time teaching to "blank boxes" on their screen. They complaint was that they find it frustratingly lonely when they look at their screen and see no faces and no one there at the other end. They also said that they couldn't see any body language to gauge the students' reaction, as if looking at a live Zoom window could tell you the accurate body language of a person.
To be clear, many of the faculty members who moaned about this were from the language/humanities/etc. department. So eventually, I had to say something about this.
What the issue here really isn't about turning on someone's camera or being able to look at a person on the screen. Rather, it is the issue of STUDENTS ENGAGEMENT on the subject matter. When we teach in class, we can judge how much the student is engage in what we are teaching, and there are many face-to-face interactions that engages the student into understanding the material.
We can't do that in an online lesson, be it synchronous or asynchronous. Treating an online lesson the same way as you would a f2f class will suck, as I've said many times. As an instructor, we have to rethink EVERYTHING when we teach things online, because the whole emotional/psychology of things are different.
I told my faculty colleagues from other departments that, if anything, *I* have a greater need to see my students in terms of being relevant to the material being taught, and not just for my psychological needs. I told them that when I teach the topic of magnetic field, such as when a charge particle moves in a magnetic field, we find the direction of the force acting on the charge particle using the cross product depicted by the so-called "right-hand rule". When I taught this in class, I can see how the students were lining up their right-hand and how they "curl" their hand to finally look at their thumbs to show the direction of the force.
So here, there is a direct and academic need to be able to see what the students are doing, and not simply just for my benefit. Thus, if anyone here has a greater claim to want to see the students during a lesson, I argue that it would be me. Yet, I make no such requirement to the students. I told them that if they want me to verify that they are doing the right-hand rule correctly, they should consider turning on their cameras, and that was it. I don't bemoan the situation that I couldn't see my students, etc. and it somehow made it feel "lonely" or as if I'm talking to nobody. It isn't about me. It is about the students!
I think that a lot of people do not realize the extra and unique challenges of teaching STEM subjects remotely/online, and this includes non-science administrators and faculty members. STEM faculty members should make their voices heard more often, and be involved in the relevant committees so that we don't get left out in course design, etc. Otherwise, a lot of things that they think will work, won't for the courses that we teach.

I'm sorry if this is old new, but I just found out about this recently.
I read a rather amusing account on why AW 1/3 pounder lost out to McDonald's quarter pounder, even though they were both at the same price.
Confused why AW's burgers weren't able to compete even though the burgers were priced the same as their competitors, Taubuman brought in a market research firm.
The firm eventually conducted a focus group to discover the truth: participants were concerned about the price of the burger. "Why should we pay the same amount for a third of a pound of meat as we do for a quarter-pound of meat?" they asked.
It turns outthe majority ofparticipants incorrectly believed one-third of a pound was actually smaller than a quarter of a pound.
I hate to say it, but this is no longer surprising to me. I look back on my take on the public's understanding and perception of science, technology, and math, and the dismal state seems to have persisted. Nothing has changed. In fact, when I said this back in 2010 ....
As scientists, we cannot forget this, because it explains the fickleness in the support that we get. That overwhelming support that is there one day can easily go away the next day, and not because of some scientific evidence, but possibly because someone else has better bells and whistles.
... I just never expected it to be illustrated so glaringly during the past few years. Many in the public do not have the ability evaluate the validity of a claim or evidence, and science can easily lose its support because someone else has a more attractive message, even without any valid evidence.
What are the odds that this is the root cause of our debacle today?

Finally, the reason why we should wash our hands for a minimum of 20 seconds has a physics explanation.
The research work was published in the Physics of Fluids journal, which so far has been quite an active journal in publishing papers related to the physics of the coronovirus transmission, making them available widely to the public.

The double-slit experiment continues to be of interest with respect to quantum mechanics, even after so many years. I've mentioned about this many times, with this one being the most relevant here to this particular post. And note that I made that blog entry back in 2013!
This time, Don Lincoln of Fermilab has released a video on the topic of the double-slit experiment and how it is relevant to QM.
BTW, has he lost weight? If he has, I hope it is on purpose and not due to an illness.
In any case, watch the video and check out the link that I gave. This issue doesn't look like it will be resolved anytime soon unless some new experiment comes up.

Fall semester 2021 is looming, and many schools are going back to in-person, face-to-face classes, at least here in the US. The pandemic that caused us to teach remotely has forced many of us to hone our skills as instructors and adapt them to the online environment. I mentioned earlier how I decided to enroll myself in an online program to get certified by my institution as a qualified online instructor. I had no intention of wanting to be an online instructor, but I wanted to take these courses because I needed to learn the important skills and methodology of being an online instructor because, whether I like it or not, and whether I want to or not, I was going to be delivering my lessons online. And I did, for the next 3 semesters (including summer).
The thing is, my training as an online instructor may actually have improved my overall skill as an instructor, even for an in-person setting. There are many important lessons that I learned from that training program, and I fully intend to use many of them when I go back to in-person teaching. What brought this article about was a discussion I had with a few of my colleagues on whether we will use any of what we learned from the online training courses when we go back on-site. All of us unanimously said yes.
So here, I want to outline a few of the things that I had used in my online/remote classes that I will continue to use in my in-person classes.
Remote office hours. God yes! I no longer see the need to have specific office hours at a specific location. Oh, I am still going to publish one office hour on-site, but the other office hour will be via Zoom that students can drop in remotely. Not only that, I'm going to make it very flexible for students to make an appointment to see me via Zoom at almost any time of the day if I'm available. Students are no longer restricted to seeing me only when they are on campus.More extensive use of the Learning Management System (LMS). Before the shutdown, I have been using the LMS to record grades, to post announcements and the course syllabus, to upload my lecture notes, and for the students to submit their lab documents, etc. However, now, I will make even more use of the LMS after what I have learned from online courses. I will continue to use the discussion feature, although not as extensively as I did for the online classes. I find that students who are either shy or do not actively participate in person, often make more use of the discussion feature in their participation with the class. This discussion feature could be an extension of the labs, where students get to give their opinion on the experience of a particular experiment, or what they expected or didn't expect.Related to the LMS, I will keep the design and layout of the LMS page based on what I've learned from online courses. This was the biggest cosmetic and design change that I have adopted. Having weekly module that contains EVERYTHING that a student needs to do and finish that week makes so much more sense now. The surveys that I had done seem to indicate that this is highly successful and that students were able to navigate the LMS and find everything that they need easily.
Before the pandemic shutdown, I was running a flipped classroom, so I was already making use of online lessons, videos, etc. I was also using clickers for the polls and a form of peer-instruction during my lesson. I adopted this for my online lessons. So this won't change when I go back to in-person classes. However, it think that I want to add a lot more video lessons that students can use as additional resources for when they are out of class. It just means that even when they are not in class, they will be able to review the lessons of that week via other means and other sources.One of the most important aspect of online courses is student engagements. It is crucial because this is one of the most difficult thing to accomplish in online classes, and yet, it has been shown to be an effective means to convey the lesson and get a student interested in it. This is not that big of a deal for in-person classes because, well, the students are there and you can engage them with via many things in class. However, I want to formalize this engagement even when it is easier to do during in-person classes. Before the pandemic, I was already running what I would call "Studio Physics" classes, where the students have frequent discussion when other students, and even perform the demonstration of certain physics phenomenon themselves as part of the lesson. I want to increase this even more. While I had used web applications such as the ones from PhET, I want to use more of these so that they become on-going "projects" for them to investigate outside of class hours. During the past year and a half, I found a lot more websites having many different physics online simulations, "labs", and other applications that had used in my online courses. I found many of them that would be very useful to assign to students even in an in-person class. Again, a lot of this could be part of their discussion task where they discuss and report what they learned or discovered while using these web apps.Clearer, more extensive and detailed feedback. In an online course, student and teacher often do not interact either live, or often, and feedback often does not come fast and quick, unlike in-person interaction. So feedback on something, especially on an assigned and graded task, must be as clear and complete as possible that first time. This includes the tone of the feedback where we were told be mindful of how the feedback might be perceived by the student. While this may not be as crucial in an in-person environment, I still intend to make full use of the feedback feature on the LMS to give a detailed assessment on a student's work. I think that having it in writing makes it more concrete and gives the student a clear and more permanent evaluation, especially if it involves something done online such as the discussion forum.
I'm glad that I got the training that I needed to be an online instructor, even when I have very little desire to be an online instructor. The skills and technique that I learned were valuable, and in some ways, I hope it made me a better teacher both during this remote-learning phases, and when I go back to in-person instruction. We shall see if this is the reality for in-person instruction soon enough.

The ridiculous battle during the pandemic on wearing masks, social distancing, and other restrictions reveals the lack of understanding among many in the general public on how science works, on what is considered as valid scientific evidence, and how our knowledge progresses as more and more evidence and data accumulates. I continue to be amazed at the reasons why some people still resist wearing proper face masks. I can understand if they find it uncomfortable (who does?) and that it is inconvenient (who thinks otherwise?). However, if the reason given is that masks doesn't do anything or isn't effective in reducing the chances of the virus being spread, then I want evidence to back that up.
This is where the public lack the understanding of (i) the nature of valid, scientific evidence, versus simply something you read on Facebook, news websites, or even from talking heads on TV, (ii) where to find such evidence or what should you pay more serious attention to versus those other sources that I mentioned. Here, I want to contrast the type of information that is contained in a scientific paper versus what you find in news article or many public online websites.
(1) When you read something in the news on a typical mass media source, you are told the content, but very seldom are you given proper, exact citation. At best, the type of citation that would be mentioned would be something to the effect that this was published in such-and-such journal or book, etc. Worse still, often times the sources are not even cited, so many of these things are stated as if they are facts, and facts that many of us are unable to verify on our own, if we wish to.
In contrast, scientific publications require exact citation. If you say that this result is in agreement or support by recent discoveries, you must give bibliographical references to those sources, i.e. name of author/s, name of journal where it was published, what page/volume number, date it was published, etc. These details are crucial in someone else verifying the sources of the claim. This is what is often missing in many general public articles, and unfortunately, this is often the source of Fake News, because exact evidence and sources to back the claims are either bogus, unreported, or unrevealed, which prevented anyone from double-checking their validity.
(2) News report and online articles often ignore contradicting evidence. When someone claims that he/she got sick after receiving a vaccine shot, why doesn't he/she consider why a lot of other people didn't get sick? Of if receiving a vaccine shot makes one "magnetic", how come other people aren't? This can also be applied to a lot of "news" programs that reports on certain occurrences that was due to something, but ignore other instances where those occurrences do not happen.
In scientific papers, this is a no-no. In fact, as a referee for several physics journals, I often will check if the authors are ignoring contradicting experimental evidence, or other papers that may be in the opposite to what the authors observed or claiming. These contradictions MUST BE ADDRESSED, i.e. they are not swept under the carpet or just ignored. And they must be addressed in terms of scientific reason, not simply by claiming that the contradicting results were made by Democrats, Republicans, Muslims, Jews, liberals, conservatives, etc. Look at how many so-called discussions or reports attached labels as a means to dismiss something. Such flimsy tactics do not wash in scientific papers.
(3) General public articles and news lacks details and clarity. I read a news article last year where a family decided to go to Walt Disney World in Orlando, FL, and when they got home, they tested positive for COVID-19 and immediately blamed their presence at the theme park for being infected. The news article didn't mentioned any other details about their trip. It did not say if they took a plane, didn't not say how long they stayed, whether they only went to the Disney theme park or did they also went elsewhere, and if they drove there, did they stop anywhere along the way, etc. There was a huge amount of information here that was missing even for a casual reader to be able to clearly analyze the validity of what the family was claiming.
If this claim is to be analyzed scientifically, then an epidemiologist would need to do really detailed tracing of every activity that the family did. Casual and speculative connection between A and B are usually insufficient to draw up valid conclusions.
In a scientific publication, every detailed of a calculation, every detail of the experiment, and every detail of how the analysis was done, must be clearly revealed. Often times, the experimental setup and equipment may had already been published elsewhere, and those will be cited as a reference. Similarly with the calculation and analysis. These details allow for an independent investigator to not only double-check what was done, but also to duplicate the experiment if necessary to see if the results are reproducible, which is a pillar of all scientific experiments (and why the Fleishmann and Pons cold fusion claim failed).
(4) Scientific papers are permanently recorded. They are not like Twitter feed that can be deleted, or news article that may be difficult to find anymore, or Facebook postings that have disappeared. This allows for future citations by other papers, and allows for continuing evaluations, advancements, refinements, rebuttals, contradictions, etc. There is a clear paper trail of who said what and when, which means that it is hard to deny or lie about something, or claim that someone didn't say that or didn't do that.
The whole point in all of this is not to force you to read scientific papers. It is ridiculous to insist that because many of them are not easy to read and are written for other experts. Rather, it is to distinguish on the nature of the evidence, and that if something is backed by proper scientific sources, then the evidence has a greater degree of validity and support than something that someone just rattled off on a TV talk show or on some Facebook post. It is unfortunate that many people, especially politicians, give equal credence to someone testifying that their bodies became magnetized without bothering to invite an expert to debunk such silliness. It seems that whole topics in physics, biology, and physiology were ignored to give air to this craziness.
It is the inability to evaluate the validity of the so-called evidence is one of the fundamental reasons why we are in the state that we are in today.
"But ZapperZ, the topic is about the scientific evidence for airborne transmission of the COVID virus. Where is it?", you asked.
Good question. I guess this is the long, circuital route to point you to this Lancet article that contains the evidence, and the references to the scientific papers, that support the claim. Compare the types of research that were done, the analysis that were performed, and how the conclusions were drawn, and compare that with the types of "evidence" presented in the popular media and TV news programs.
Have fun reading!

The climate of fake news and anti-science during the last few years have given me the impetus to be more conscious and deliberate in alerting my students on how we analyze something, on making rational judgement based on evidence, and how we come to such-and-such conclusions. To me, the issue of believing in fake news and accepting something based on flaky evidence does deeper than what it seems. It boils down to the inability to systematically and analytically evaluate the validity of something. This inability is really a serious issue and could be the root cause of what we are seeing today.
This type of skill is exactly what we use and practice all the time in science. So when I get a group of students, especially if they are non-science students who are taking the course only to fulfill their science credits, then I can't waste the opportunity to instill in them this invaluable technique and methodology that are often used in science.
Using the period where the pandemic forced us to teach remotely, I made extensive use (and still do) of the discussion forum. This is one form of student engagements that many online training courses have deemed to be essential in making sure that students feel connected and engaged with not only the subject matter, but also with other students. This medium gave me the opportunity to get the students to think things through and to present logical and rational arguments.
One of the topic that I presented was to require them to critically address a belief about the cause of the Earth's four seasons. We were going over the reason why we (at about latitude 41 degrees North) experience seasons. I presented a topic whereby someone claims that since the Earth orbits the Sun in a slight elliptical orbit, the seasons are caused by the varying distances between the Earth and the Sun, meaning that when the Sun is closest to the Earth, we have summer, and when the Sun is farthest from the Earth, we have winter.
The task was for the students to come up with typical and common everyday observations and/or knowledge to show why this idea is wrong. In other words, find a very direct and convincing way to falsify the argument.
I thought this was a straight-forward assignment and discussion topic. Unfortunately, I was quite surprised that almost 3/4 of the students didn't fulfill the briefs. What they did instead was to give the explanation for the cause of the seasons, which is the tilt of the Earth's spin as it goes around the Sun. While this is the correct explanation, it does not falsify the original argument. I tried to tell the students that what they did was to present to this person an alternative explanation on why the seasons happen, but they haven't shown evidence why the original premise was wrong! They have not falsified the first idea.
When we do that in an argument/discussion, the person who holds that idea can easily say "All you have done is showed another possible explanation. You haven't proven to me why my idea is wrong. So why should I change my mind?"
Providing an alternative explanation, even if it is the correct one, is distinctively different than falsifying an idea. In falsifying an idea, you do not need to actually have an alternative, correct explanation. In this case, you really don't need to know that the Earth's tilt is the cause of the seasons on Earth. All you need is to examine the original claim, and find evidence that contradicts that claim. In this case, what you can do is assume that it is true, that the seasons are caused by Earth's varying distances from the Sun. If that is true, then the entire Earth would have the same season at the same time of the year, because the entire Earth is at the same distance away from the Sun. Yet, it is common knowledge that Australia, New Zealand, South America and Antartica are in their deep winter freeze while we in the Northern Hemisphere are basking in our summer heat. This observation is clearly contradictory to the original claim, which means that this is a falsification of that idea. It carries no other "baggage", i.e. it doesn't promote an alternative explanation on the cause of Earth's seasons.
It found it challenging trying to convey this message to the students. They learned about the Earth's tilt and the cause of the seasons, and when they were given this topic, they immediately jumped on providing the explanation that they just learned (and understood) without thinking about how to actually address the topic of the discussion and knowing the difference between falsifying an argument versus providing an alternative explanation.
Sadly, the same situation happened again later in that semester when I brought another scenario for them to address: the claim that the phases of the moon are due to Earth's shadow of the light from the Sun. Once again, they were asked to falsify the claim, and once again, more than half of the students provided an alternative explanation on the cause of Moon phases rather than falsifying the idea.
In teaching science courses to non-science majors, I've grown more skeptical about the public's ability to analyze something. What I have observed regarding the "controversy" surrounding vaccines, the wearing of face masks, and even climate change, reinforced my skepticism about someone 's ability to either think things through, or even know what a valid evidence is. My post on the nurse who claimed that the COVID vaccine makes her becoming magnetized is one such example. Something that should have been easily checked and verified by a high-school physics student now somehow is gaining traction. That claim can be easily falsified (and have been), even by people without much scientific training and without knowing any alternative explanation on why certain objects might stick to one's body.
It requires skills to look at an idea, analyze it thoroughly, and rationally argue on its validity or its fault. It also requires skills to know what are valid evidence and what are not. Often times people confuse opinions and conclusions with facts/evidence. Talking heads on TV often spew out opinions that a lot of people mistaken for facts. In a science class, it is more important than ever that instructors make a deliberate effort to show the process of how a scientific idea becomes accepted, what kind of evidence would be considered to be scientific (why do we have to measure the forces at various extensions when just one is sufficient to find the value of the spring constant in Hooke's law experiment?), and how to challenge an idea and show that it may not be correct.
A science education is now more important than ever, not just for the scientific content, but also for the skills that come with it.

I chat often with my colleagues from the English and other departments. I often envy them because many of their assignments have the ability to incorporate the hot topics of the day. They often assign tasks such as essay writing that involves subject matter that are relevant for the current times, such as writing about Black Lives Matter movement, the pandemic, etc.
While I always want to do the same, it is less obvious and not so straight-forward in bringing the same thing into a physics lesson. I had managed to incorporate some over the years (direct observation of blackhole in an IR image while we were studying EM waves as an example). But to incorporate topic-of-the-day to match the topic of the lesson is not that easy.
But this time, I managed to do it, and it was a doozy. We were about to dive into the topic of magnetism and electromagnetic field when I stumbled upon a goldmine. It is the claim that the COVID vaccine can cause one to become magnetized!
Now, my class is still being done remotely, so I make extensive use of the discussion forum as one means of student engagement. When the subject of magnetism comes up, the topic of discussion that I created was for the student to read a couple of news reports on this claim being made. The task is not to either belittle or make fun the claim or the people who made them. Rather, it is to rationally examine the claim and use well-established scientific facts to analyze the validity of such a claim. The students had to do this based on what they have learned about magnetic field, the type of magnetism in a material, and what type of materials are attracted to a magnet.
They were encouraged to make their own at-home observation. Everyone had refrigerator magnets, and I asked them to try and stick various items to the magnet, especially the ones that had been used in the testimony reported in the news article. A student also had the bright idea to use a compass that she had and see if the compass needle changes direction if she brought it against her skin (she's fully vaccinated) or her parents' skin. She cleverly argued that if something has a strong enough magnetic field to attract a spoon, it should cause a noticeable deflection in the compass needed.
This ended up being a lively discussion topic in the discussion forum, with students posting pictures, videos, etc. either one something they found, or something they did. It forced them to sift through what they read in the news to find the details that they can analyze and compare with what they learned about magnetism. They studied the validity of the claim only from the scientific point of view without passing any judgement on politics or personal beliefs.
The whole thing went better than I expected. The students were engaged because this was a current and relevant topic, and they get to see first hand how something that they just learned was actually useful enough to be used to analyze a news item. They get to see that a physics topic is not just something esoteric with little direct practical use in everyday life.
Oh, I should also mention that this is an algebra-based General Physics course that is tailored to life-science/pre-med/biology/kinesiology major. Many of the students are quite familiar with the human body and biological functions, so their discussion included several possible explanations on why something would or would not stick to a human skin without any consideration about magnetism.
It is on days like these that I get great joy in being a teacher.

This is a rather fascinating study of two different physics faculty members at two different schools. I haven't finished reading it carefully yet, but I thought I'd post the link here and let you read along with me.
Abstract: This paper investigates the interactions between context and professionaldevelopment of physics instructors in a case study of two physics faculty. Aphenomenological-case study approach was used to analyze two physics faculty atdifferent institutions over a year and a half using three semi-structuredinterviews each. The data enabled the identification of relevant contextelements; and the impact of these elements on physics faculty's professionaldevelopment was explored by adapting Bell and Gilbert's framework for teacherdevelopment. The analysis shows that both case study subjects used theirphysics expertise and growing understanding of their context to develop theirphysics teaching. However, this process of development was enacted differentlygiven the nature of their context, highlighting instructors' strengths innavigating their local context to improve their physics teaching. The resultsshow the subtleties of how context has a salient, complex, and evolving role inmoderating faculty's professional development. By taking a faculty-centricapproach, this paper broadens the community's awareness of the ways physicsinstructors develop their physics teaching. This work contributes to arelatively new lens by which the physics community views, discusses, andsupports the professional development of physics faculty.
What the authors call "context" appears to be broadly defined as "... the different entities that influence their professional development .. " which could include the institution, the department, other faculty members, workshops and other faculty development efforts, etc.
The study focused on two faculty members, and followed them via a series of interviews. In particular, they seem to focus on each faculty member's teaching practices and philosophy, and how they evolve and how they are able to execute their teaching ideas.
Like I said, I'm still in the middle of reading this, but I freely admit that I see bits and pieces of myself in here, especially in the struggle to implement some of the active-learning concepts into my classes, more so during the remote-learning phase due to the pandemic.

The big news of the week that got all the media coverage is the result that came out of Fermilab's Muon g-2 experiment that confirmed an earlier result from Brookhaven more than a dozen years ago. Fermilab even announced it like.
However, as with any scientific discovery or announcement, one has to take a deep breath and let the process works itself out before we put our stamp of validity to it. This is because there is a theoretical calculation that has also been published along with this result that basically recalculates what the Standard Model predicts as the magnetic moment of a muon, and they found that the new calculation produces a result consistent with the experiment. In other words, there is no new physics if this calculation is verified, because the old Standard Model does, in fact, predicted this new result.
One of the major difficulties in physics is that in many situations, we do not have a simple equation that we can plug-and-chug to get numbers out. In fact, this is why predicting the weather is difficult, because the non-linear differential equations that need to be solved to get the number out can only be done numerically, i.e. it has to be done via some numerical algorithm.
This is made worse when there are a gazillion interactions involved in a system. So one ends up making simplifying models or adopt calculational techniques to allow us to get to some numerical answers. We benchmark the technique to known values and known systems to make sure that it gives accurate and sensible answers, but as we push the boundary even more, there is no guarantee that that calculational technique will work all the time.
The author of the theoretical paper used a calculational technique called lattice QCD. This is a known calculational model that has been described in simple terms in the link I provided above. It appears that using this method, the Standard Model does provide a value for the muon magnetic moment that is consistent with the experiment. If this is true, then it means that the old calculation of the magnetic moment was incorrect in the first place, and that there is discrepancy between what the Standard model predicts, and what the experiment measures.
While this is good news for the Standard Model and is another evidences of why it is an amazing theory, those who are looking for new physics beyond the Standard Model will obviously not be jumping for joy. But that isn't the issue here and not what I want to highlight. Rather, it is the constant reminder that in science, and especially in such exotic areas of physics, every discovery or new ideas must not be overblown or overhyped, because those require multiple verification over a period of time. It is not a situation for instant gratification. A lot of hard work is still to come because we have seen way too many times where something that was touted turned out to not be valid.
This announcement received a lot of media coverage. I just hope that this is a valid "new physics" and not just something that turned out to be what the old theory did predict.

Being under 65 years of age, and with no major health issues (knock on wood), I was not eligible to receive the COVID vaccine in my area during the first 2 waves of its distribution.
But suddenly, it was announced by our state that starting Monday (today), higher-education workers will be included in the expanded criteria to receive the next vaccine distribution. So, after scrambling to find an appointment, I will get my first shot of the Pfizer vaccine this coming Friday, and then the second one later in April. All I can say is : PHEW!
There is certainly a push by the school to get things back to almost normal, in the sense that many of the classes are starting to be offered in person or in a blended/hybrid modality. Certainly classes that have a significant laboratory component are the ones that will probably start to be offered in person. I definitely would prefer to have the vaccine before I have to come in to the campus, so getting the vaccine now is a major peace-of-mind aspect of this whole thing.
It is certainly looking more certain that I may have to ditch my Zoom pants on most days and have to start dressing up again when I teach my classes this Fall!
