Four heavy-ish boxes of beads, all soda-lime glass in various sizes. 1 millimeter up to 4. Remnants of an old research project, untouched for years.
But it’s not like they go bad, not on a human timescale. So 60 lbs. of little glass beads, headed for storage, awaiting the day when they’re useful to someone or the space they’re occupying is more valuable for something else.
Anybody have ideas for an arts and crafts project?
Approximately half a gallon – the classic method of fastener measurement – of 3/8″, 8-32 thread pan head slotted screws. For $2.00, that’s a pretty good deal… assuming you have a plan for all of those.
Do you have a plan for all of those?
No idea why this little toad decided to rest up here, but we’re in no rush to disturb. There’s another entry just around the corner.
“CAUTION: AI does not know how to write a proper lab report. Do not risk losing easy points by trusting something that has never attended labs.”
Entirely reasonable position from instructors: do your own work, and please don’t cheat.
Of course, we also get this message in the same week:
‘Twas update-the-computers season in the department, and the new Windows laptops have eliminated the right-side Control key in favor of one for Microsoft’s AI. Ditched a very useful key for one that’s utterly pointless.
For example: with only a single Control key on the left, it is no longer possible to log into this laptop with a single hand, even if you’ve got hands like Andre the Giant.
Sigh.
With the right crystal structure, as with calcite (a form of good, old calcium carbonate), you get some neat effects. With a refractive index that varies depending on the polarization of the light passing through, a chunk of iceland spar is birefringent and causes a visual doubling effect of the objects seen beyond. How cool is that?
Behold, Canis Major, the Greater Dog! He’s such a good boy!
Sirius-ly.
Bar magnets, over time, lose some of their intensity. From time to time, a top-up’s in order, using this glorious little contraption.
Two magnets, a conducting bar, and the fantastic sound of BZZZZ-THUNK as those iron atoms line up. Cool!
Discovered inside an old wooden desk, burnt into the solid-wood drawer. No complaints about the quality of construction, to be honest. But how long has it been since furniture makers burnt in their brand with red-hot iron?
The drinking bird, our unofficial department mascot. Even when one takes a tumble – and when it comes to glass bird versus floor, the floor always wins – there’s a great deal of respect for our top-hatted friends.
Kind of surprised someone hasn’t made up T-shirts yet, to be honest.
Welcome back, spring semester!
Is that a Dalek in the loading dock, cleverly disguised as tiny TARDIS?
