    It is a fantastic day out here along Lake Michigan. https://chirp.cooleysekula.net/attachment/eba840e8a3cd30b00294323b2a05bf657eababfff1e99f513554f3fc2c211083/view

      From mcnees@mastodon.social on Mastodon: Though Nightingale died in 1910, there is a wax cylinder recording of her voice made in 1890 by US Civil War veteran George Edward Gouraud. Colonel Gouraud was the British representative of the Edison Phonograph Company. You can listen to it here: https://www. youtube.com/watch?v=8PZaHp7mkq A

          From http://status.hackerposse.com/url/24447 on Mastodon: # CMSPaper 1216: The η (=eta) is a special particle.This paper finds a new way the η can decay: into four muons. This is important because it measures muon-photon interactions, and quite accurately at that. That is a precision test of theory predictions, including some inputs to the muonic magnetic dipole moment.…

              I was today years old when I helped to estimate the height of a leak in a cylindrical tank using measurements of fill height and leak rate. I was inspired to try this by my Honors Physics students from SMU, who, over many years, tried to estimate interesting things from limited data.

                  Here is a wide-angle shot looking down into the water shiield after concluding the fill today. The tank is about 110 inches in diameter and the water is 90 inches deep. I think this is just a thing of beauty, like dark matter detector meets warp core. The vessel in the center is the pressure vessel, which holds mineral oil. Inside the mineral oil is a set of jars filled w…

                    Had an absolutely excellent time again today in the underground laboratory at SNOLAB. Worked with the PICO team to put another ~6000 liters of water in the shield tank. Ran a little experiment over at HALO involving Newton’s Laws and Maxwell’s Equations. Scoped out some oxygen sensors for a summer research project. Oh, and had a great time streaming a sample loaded in…

                          Yesterday was a busy day! In addition to management activities, it was great to begin welcoming summer research students to # SNOLAB and to begin data quality “shifting” for # HALO . Also kept thinking (and calculating) about evaporation and other ways of losing water from the # PICO shield tank as we plan to continue filling the water shield.

                                I have my own workaround for just this issue.
                                I raise my hand to the "Stop/Hold" position.
                                Get to a point where I can stop and leave myself a note on the next thing to do.
                                Then let them interrupt me.
                                I have even done this to my former boss and the owner. It wasn't long before they adopted it for the same reason.
                                YMMV

                                Also spent part of the weekend thinking a little about evaporation of water from the PICO shield tank. It was a very satisfying dive, even if I don’t trust the conclusions too much. That said, I am slightly more comfortable with the mathematics of evaporation rates than I was 24 hours ago.
