It’s February 3rd 2020, which means that today is two days after *Imbolc*, a Gaelic festival marking the point halfway between the winter solstice and vernal equinox. The 1st Day of February is also the Feast day of St Brigid of Kildare (c. 451-525), one of Ireland’s patron saints along with Saints Patrick and Colm Cille. One of her miraculous powers was the ability to change water into ale, which perhaps explains her enduring popularity among the Irish.

In Ireland this day is sometimes regarded as the first day of spring, as it is roughly the time when the first spring lambs are born. It corresponds to the Welsh *Gŵyl Fair y Canhwyllau* and is also known as the `Cross Quarter Day’ or (my favourite) `The Quickening of the Year’.

Today is, appropriately enough in the light of all this, the start of the Spring Semester of teaching at Maynooth University, the third Spring Semester I will have experienced here. The weather has even played along; it has definitely been spring-like. The Campus, whicgh has beenhas been very quiet for the last week or so since the examinations finished, is full of students again.

This Semester, as was the case last year, I am teaching Engineering Mathematics II and Computational Physics I. The former, what you would probably call a `service course’, covers a mixture of things, mainly Linear Algebra but with some other bits thrown in for fun, such as Laplace transforms. Interestingly I find the Mathematical Physics students do not encounter Laplace Transforms in the first year, but perhaps engineers use them more often than physicists do? I think I’ve written only one paper that made use of a Laplace transform. Anyway, I have to start with this topic as the students need some knowledge of it for some other module they’re taking this semester. I reckon six lectures will be enough to give them what they need. That’s two weeks of lectures, there being three lectures a week for this module.

Once again my teaching timetable for this module is quite nice. I have lectures on Monday, Tuesday and Wednesday and then the students have a choice of tutorial (on either Thursday or Friday). That means I can get through a decent amount of material each week before each tutorial. I don’t do the tutorials, by the way: that’s left to one of our PhD students, who gets paid for doing that and correcting the weekly coursework. There are about 50 students on this module, divided into two courses: Electronic Engineering and Robotics and Intelligent Devices. We don’t have Civil or Mechanical or Chemical Engineering, etc at Maynooth, in case you were wondering.

Anyway, my first lecture was this afternoon at 2pm and had a good turnout. It was so sunny outside that we had to close all the blinds. That’s quite an unusual event for a February lecture!

My first Computational Physics lecture is on Thursday, after which it will be back to the Department for some frantic behind-the-scenes activity ahead of the afternoon lab session, which is in a computer room near my office. Students attend one two-hour lab session in addition to the lecture, on either Thursday or Tuesday. The first lecture being on Thursday the first lab session will be Thursday afternoon, with the same material being covered the following Tuesday.

While my teaching duties are the same this year as they were in the corresponding semester last year, there is a significant difference this year in that I am now also Head of Department. Either side of my first lecture I had to attend a meeting of the Faculty Executive for Science & Engineering, a meeting on `Project LEGO’ (which, sadly, did not involve any actual Lego but was instead about the proposed redesign of the University’s website) and a meeting of Academic Council. I have also been trying to sort out tutors and tutorials for the forthcoming Semester: these don’t start until next week so there’s time, but it’s quite a challenge to get everyone sorted out. A few timetable clashes have also come to light. So, in summary, I’m a bit worn out after today and will shortly go home to vegetate.

At least I didn’t have to find time for the regular Monday afternoon *Euclid *telecon in which I usually participate. There wasn’t one today because the working group of which I am part is actually meeting in person for a few days… in Paris! I couldn’t go because of all the above!
