I would never attach my Credit card to an app store, due to having a 6 yr old in my house who loves to play with my phone.
Having a threshold at $1 means other developers also wont try to undercut at $0.9 , and drag the whole pile of apps down to $0.05 eventually.
You missed the part in the video where they turn the track upside down. If they were only using the meisner effect, the puck would drop to the ground. They have found a way to control the magnetic field more precisely, and pin the object in place. ( ie, a useful example of the engineering techniques now possible with the effect, instead of just ooh, shiny. )
The article states that because they moved the atomic clock used for measuring time, their time synchronization would be different for the clock while it was in italy, then when the clock was in switzerland. The difference in time synchronization is what they measured, not the speed of light.
Of course, they knew about this effect, & tried to off-set it by using GPS signals from the same satellite to correct. TFA says that GPS signal has error in time sync about 100ns, which is in scale with their measurement error.
Should we aspire to a global government or just nuke them from orbit ?
I know they have tried to factor out obvious stuff, but wouldnt the rotation around the sun ( or galaxy) mean that its possible they're hitting a target that's moving "closer" to the source?
