Time for some slightly delicate Wattbike surgery…

My garden camera once again showing how effective it is at catching the local wildlife eating.

I was slightly in two minds, but that cleared things up.

Those of us who protested in London in February 2003 remember that if Mr Blair thinks a war in the Middle East is justified, then it really isn’t.

With the Sun filters in, it really isn’t an issue β€” auto exposure tends to overexpose a little, but not to any serious extent.

Last night’s update: finally sorted that itch.

Quantisation does not define whether something is a count noun in English.

If you really say things like β€œhow many data do you have?” Then your grasp of the language is… limited.

Honestly, it should make very little difference, so just be down to personal preference. If you are applying for a job, you’ll likely provide a publication list. If someone is checking out your record, they’ll likely use Orcid or Google Scholar, which you can populate yourself with both names.

And the English language.

I would usually say β€œdata point.”

One more time:

β€œData” represents a plural concept, but it is a non-count noun (which is why it is β€œhow much data do you have?”, not β€œhow many data do you have?”)

Non-count nouns take singular verbs (β€œthe water is in the cup.”)

So β€œthe data was analysed”, not β€œthe data were analysed.”

I think I may have been the only person who ever published data from the Faint Object Grism Spectrograph.

I was observing on the MMT with the unfortunately-named FOGS spectrograph, which could obtain six whole spectra simultaneously!

Time for a little solar astronomy with the #Dwarf2. So much for that Grand Solar Minimum, eh?

Any positive stories to share about PhD supervisors?

Mine is the restraint he showed when he woke me at 3AM on my first observing trip to tell me the clouds had cleared so we could get back to work, and I told him exactly where he could stick the telescope.

I can recommend the Helarctos camera by @naturespy.bsky.social that I was given for Christmas, from which I’ve been posting shots from our yard. All solar powered, so no issue with charging, though you do have to be reasonably close to it to download content using its WiFi.

Inspired by @tronicsfix.bsky.social’s latest video, I went nosing through a dusty drawer and found this. Happily, apart from needing a new charging cable, it didn’t require any work at all.

A friend has had a recent provisional cancer diagnosis overturned, when further imaging showed the lung lesions were due to Covid.

Yay!

But also, fucking Covid!

Very pleased with this final edit of the video of the tawny owl who posed so nicely for my back yard trail camera. πŸͺΆ

One other very positive thing to pick up on is the disquiet expressed by the Committee on the volume of concern that it had received in correspondence from the Learned Societies, echoed and conceded by the Minister.

One suspects they wouldn’t be scrabbling so hard to fix things without it!
