Unutterably Silly Question Everything?

[nana77]

Might someone guess that, if ordening them on Amazon, it would then be possible to return the idem as being "not working"?

[DNSB]

Would Amazon refuse the return since the glasses are working as designed?

OTOH, do you actually expect those glasses to work?

Are you interested in buying a bridge?

Wouldn't that depend on which bridge and whether the seller actually has the right to sell it?

Would the Brooklyn bridge work for you?

A Phoebe Mary Waller-Bridge?

Spoiler:

The Bridge, later Waller-Bridge, family were soldiers and clergymen, who came to rank among the landed gentry of Cuckfield in Sussex.[9][10] Her grandfather, Cyprian Waller-Bridge (1918–1960), "a Wodehousian sort of character... 'the eccentric son of an eccentric vicar'",

Jokes apart, I was just curious,

With this famous, blushingly funny illusion, see the bones in your hand or start a riot at the office pretending you can see through clothing. Look at any bright point of light such as city streetlights, holiday lights, or candles and see the words "X-Ray" magically appears. Take X-Ray Specs to parties, get-togethers, and hospitals. X-Ray Specs are a great novelty item and ice-breaker for doctors, dentists, radiologists, stockbrokers, detectives and security personnel. Not made out of plastic.

Kind of bummed they were cardboard but still kind of cool.

Spoiler:

Loving this revievs, btw:

We had been using a Nikon XT V 160 with 160 kV source to inspect BGA ball pad joins in our PCB fabrication line, but the costs were high and it was difficult to use. When it was time to renew with the vendor, we decided evaluate to these X-RAY SPEX as a possible alternative.

PROS:

1) Low (no?) energy beam. These SPEX do not appear to impart any energy or charge to the sample under view. This allows longer dwell time without worrying about ionization or lattice dislocations.

2) Size. When folded, these literally can fit in a lab coat pocket or desk drawer. The machine we replaced was the size of a small car.

2) Intuitive use. There is no user interface to learn, just put them on and look at the sample.

3) Low (no?) power. These appear to be self powered - there is no need for a dedicated high amperage circuit.

4) Low (no?) dosing or exposure limits. We have not had a single dosimeter alert with this device, even at 1 millrem threshold. These are designed for looking at living tissue (hands and full body scans) and so must use some other method of action that limits biological interaction.

4) Low cost. These cost about $10 per unit as a one -time purchase. The machine we replaced was running more than $2.5 million annually between the lease, maintenance, licencing fees, and operator training costs.

CONS:

1) Non-concentric imaging. Since you wear these SPEX on your head like you would with glasses, it is not possible to rotate the field of view without also impacting the position of the center-point.

2) Fiber and particle release. These are made from standard non-bonded cellulose cardboard and so release airborne particles during normal use. This really precludes their use in class ISO 3 or better clean rooms.

3) Large spot size. There is effectively no magnification. The smallest feature you can resolve is basically the smallest thing you can see with your eyes.

4) No tomography. You can move your head around to see different angles, but there is no point cloud or way to reconstruct tomographic data. What you see is literally what you get.

5) Low manufacturing quality. These are basically just a piece of cardboard with a striated filter at about 633nm (looks like a dyed feather).

6) No support. We reached out the vendor for guidance in dealing with some back-scatter issues and got no response (we eventually figured out that must wear these SPEX on the *outside* of your safety goggles).

All said, these SPEX have been a valuable and effective addition to our line. As long as you can live with their limitations, I would recommend them for people looking for an alternative to high cost, high power, hard to use, and dangerous tube and cyclotron based x-ray inspection systems.

Is that a bridge too far?

[Solitaire1]

Why would a bridge be too far if you need to cross it? Could that mean that the bridge is too long to cross?

[DNSB]

What if the bridge was never finished? Does it bring back memories of Wile E. Coyote?

[nana77]

Is it, in there, a Gandalf, saying not to pass through?

In Old Norse, the name means staff-elf. This is reflected in his name Tharkûn, which is "said to mean 'Staff-man'" in Khuzdul, the language Tolkien invented for his Dwarves.

Since bridges are not ACME products, wouldn't that mean that they are safe to use?

[DNSB]

Do you also remember all those scenes with Wile E. Coyote standing on air?

[Martinoptic]

Is that where air today gone tomorrow comes from?

Do slithy toves really gyre and gimble or is that a urban myth?

Isn't that one of the Laws of Cartoon Physics? See the following:

Don't they need a Wabe?
