It’s 3rd February 2019, which means that today is two days after *Imbolc*, a Gaelic festival marking the point halfway between the winter solstice and vernal equinox. This either happens 1st or 2nd February, and this year it was former, i.e. last Friday 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’.

I wrote a post about this time last year, on the day I gave my first ever lecture in Maynooth University, on Computational Physics, in a theatre called Physics Hall. That was on Thursday February 1st 2018. It’s hard to believe that was a full year ago. Time certainly has gone quickly this year.

Owing to the vagaries of the academic calendar we’re a week later getting back to teaching this year than last year so my first Computational Physics lecture won’t be until this Thursday (7th February) at 9am, but sadly it won’t be in Physics Hall, which I rather liked, but in Hall C – a much less atmospheric venue, but one rather closer to my office, which will be handy if I forget anything (which I am prone to do). There are about 25 students taking this module, a few down on last year, which means they should fit comfortably into our computer lab. I’m not surprised they moved the lecture, really. The capacity of Physics Hall is 90, and even last year I only had about 30 students. Still, it did have a piano (which Hall C does not):

Computational Physics doesn’t start until Thursday. Before that I have to start my other module: Engineering Mathematics II. This (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.

By coincidence rather than good planning, the 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.

Campus has been very quiet for the last week or so. The exam period finished in late January but lectures don’t start until tomorrow morning (Monday 4th February) so there have been few students around. No doubt it will be a different story tomorrow. I’ve done my first week’s notes and compiled my first problem set so I’m more-or-less ready to go. First lecture at 2pm tomorrow in Hall H, which is one of the rooms I taught in last term so at least I know where it is!
