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?
There are many tools for communicating new ideas, including candy. Boxes upon boxes of candy intended for consumption in other countries, apparently.
Ah, physics. Where we have an eclectic assortment of desk toys and mostly-useless gimmicky trinkets because their very nature, the quirks of physics they embody, are helpful explainers of scientific principles.
And while their appeal is typically short-lived – how many times before the levitating magnet loses its novelty? – that ooh! factor only needs to work the first time.
Look, it’s old, doesn’t work, and isn’t worth the cost and effort to repair. We’re assuming, of course, unsure who deposited it in the loading dock, and curious where it – or its constituent parts – is headed next.
At least it’s amusing?
Another coffee can, this one half-filled with old keys, most unlabeled, almost certainly all of them to locks long gone. Not like “bucket of keys” is a prime organizational strategy, so one supposes these can be used for some exciting new arts and crafts project?
Apparently, at some indeterminate point in time, the second floor held cabinets with a breathing apparatus inside. Respirators? SCBA systems like firefighters use? SCUBA systems like divers use? Pretty confident that those’re long gone.
This one has become disconnected from its key, so your guess is as good as ours. What useful information could that possibly offer? Like, even if we knew which key it identified?
