It might be nice to submit this to @quantumjournal, except that means dealing with the evil axis of @arxiv_physics and their "preprint" gatekeeping. I think I'll pass...

(and... Why do I have to select my own editors? That's just more gatekeeping)

Weekly lab report:

I collected and plotted temperature and %relative humidity in the region of our laser amplifier. I now have a 12 month record. We have had humidity issues over the past year or so, but I was pleasantly surprised that the ongoing work by the campus maintenance staff has paid off.

The first of the "sample and hold" devices was tested. I installed it with the position alignment system and detector and hooked it up to the oscilloscope. I saw the expected DC signal! Varying the intensity of the beam to be stabilised was not done, but I got a rock solid position, and it behaved as expected when the beam was temporarily blocked

The next day was spent scrounging around the lab for enough parts (2 x beam samplers suitable for the pulsed laser and suitable mounts, beam blockers and SM tube with lens and ND filter for the sensor, and 2 x 15V power supplies.

A highlight of lunch in the Science staff room was watching the water start pouring through the ceiling into a strategically placed wheelie bin. I did have to adjust a wider bucket to minimise the splashes onto the carpet. This ceiling damage must have happened during the TC Alfred event a few weeks prior.

One of the joys of a PhD is managing mental health. I had an interesting episode in the lab on Tuesday which I will talk about seperately. I could not return to the lab for the rest of the week. It is disappointing, given the progress we made over the past few weeks. This was not wholy unexpected and not my first rodeo.I had taken steps earlier to manage it. This journey into the PhD is also journey into my own mental landscape. I have some thoughts and insights already 😀

Question for people who study #neutrinos :

Do you have a preferred funny nickname for neutrinos? If not, here are some ideas:

- Neuts (newts)
- Rinos (ree-noes)
- Trinos (tree-noes)
- Nuterinos (like Ned Flanders would say)
- Neu-nues (new news)
- Neu-nos (new noes)
- Tri-tris (tree trees)

I would make a poll, but their are too many choices.

If mathematics is functional vision in a cosmos of energy and momentum, what abstract practice is it that allows us to perceive and process the deeper messages woven into what we see through proof & calculation?

The infinities, the limits, the bumpy smoothness, the funhouse symmetries (maybe real?), the utterly confounding illogical puzzles…

(05 Apr) Scientists claim to find ’first observational evidence supporting string theory,’ which could finally reveal the nature of dark energy

Physicists have proposed a new model of space-time that may provide the ’first observational evidence supporting string theory,’ a new preprint suggests.

In a nutshell, all the movies show at once, but they flicker on and off so rapidly (each in its own little time slot) the screen looks a shade of white, perhaps much like white noise on an old TV—unless one happens to be wearing the required goggles...

Goggles configurable (tunable, like a radio) to shade out every other movie but one by only passing light from the time-slice assigned to the desired film.

I have some odd thoughts while reading QM stuff.

Yesterday, it came to me how theoretically simple it would be to show multiple films on one screen simultaneously to an audience able to select at will which film to watch—using modern tech simply to synchronize the sequencing of imaging required (this inspired by how QM systems manifest as 'different' depending how one looks at them).

Then I realized: what a fantastic way to visualize how radio communication works...
