IIRC, I had no liability when someone stole my credit card info (waiter at a restaurant was the likely culprit)

Yes, you can have as many nonexistent photons as you want. Dirac’s quote is from 1927, so it’s not like the whole idea of bosons had been developed very much.

And you aren’t liable for most of it, in the US. You’d owe at most $50 per card, and some cards have zero liability. That puts the burden on the credit card companies to have decent security measures. One card I have texts me for approval if the purchase breaks a pattern

The Greek right to bear serpents.

Why would there be stimulated emission under time reversal?

I’m a Gemini, so I never know what to expect

No. With the t reversal, the excited atom in the target emits a photon.

That suggests that they dissipate, which is probably the wrong way to view the classical field A static field exists. Perturbations/fluctuations happen, which are variations in time. No change unless the source of the field was somehow changed. Waves obey superposition.

That’s only time reversal symmetry. You haven’t applied the parity transformation.

I believe they are asking if deleting the files will cause a problem, e.g. if they are necessary for some program or the operating system.

You have asserted this, but I don’t see how you get there from transforming x —> -x That transform would flip the experiment - its mirror image. IOW, I don’t think you’ve done the P transform properly. Repeating your conjecture is not sufficient.

Yes, because of pushback from customers who put convenience above security.

That’s probably why it’s not seen there, since the PIN wouldn’t be something you can scan. In the US, AFAIK PINs are not required. Yet. It used to be that transactions at the self-checkout at my grocery store were limited to $50 and they checked your ID if you went to the regular checkout, but they stopped doing that after a few years. (edit: if I want cash back with my transaction, the self-checkout wants a PIN if I use the chip)

One of the things I read is that the pulsars are only measured every few weeks, which works because the GW frequency is so low. That way they can monitor multiple pulsars with their telescope time. Also explains why it took years to get the data, since the period of a 31.5 nHz wave is a year.

I’ve read that UK/European standard is to have a PIN you enter for these transactions. Is that correct?

Also depends on how the poll is worded.

I think that any small category of people have benefitted from the ability to connect. You have disaffected people in the majority or plurality group going through the motions who become aware there is an alternative that’s a better fit. It’s a bit like buyer’s remorse, but you’re finding out after the fact, and you can trade in your religion (or belief). Also the fact that you can do so online means you don’t face the same pressures of IRL interaction until (possibly) after locating a group that fits you. If you have somewhere to go, being shunned by your former group might be palatable.

Why would it be momentarily huge? It’s not going to be bigger than the external pressure. If any remains were recovered, I suspect they would be kept away from the public eye.

And what fraction of these losses came from someone scanning the card while it’s in a wallet?

But one would be wrong to claim this. Which has nothing to do with having an RFID wallet

It’s a gimmick in the sense that they’re offering a product based on the fear of a low-risk scenario, but you can attenuate RF signals. There are independent reviews of such products, but the few I’ve seen don’t seem to go into much detail about how they were tested.

That’s for conduction and convection. The corrugation creates pockets of dead air, much like double-pane glass. So if you have a temperature differential, the cardboard will reduce the rate of heat transfer. But you specified sunlight, which means radiation. The cardboard will block this, but will absorb some of the light, So, as I said, it will heat up, and radiate into the box. How much depends on details that you haven’t provided.

Temporarily. The cardboard will heat up, and radiate into the box.
