Re: Missed one

The fingerprint sensor on my 6 is not very good, it's basically non-functional - and it has nothing to do with wetness. I can train it, and then it will function for up to a day with 80% recognition, Then as time passes, in a week it is totally useless.

Fingerprint sensor

There is supposed to be a new fingerprint sensor, and new software for that function. Did you check this out? The sensor on my iPhone 6 is junk, and I have plenty of company!

Re: Rolex

Repairs on an expensive watch can be very costly. Check the FedEx insurance cost!

I once sent a Rolex President into the Rolex New York repair center for service. It was stolen by a worker there (but replaced by Rolex).

OHM MY GOD! Move over graphene, here comes '100% PERFECT' stanene

What are the properties of this proposed superconductor.

Superconductors have peculiar resistive properties. A conventional superconductor has zero DC resistance, but at elevated frequencies it is observed that resistance is finite and increases more rapidly with frequency than can be attributed to something like skin effect. The resistance increases faster than that of conventional conductors and ultimately reaches a crossover point. Operation above the crossover frequency is degraded with respect to normal conductors. So, the issue is -

What is the crossover frequency for Stanene?
