That part is cool but worldwide quantum internet? Quantum entanglement won't change communications. Information exchange speeds are still bound by the classic laws of physics to c.

I guess the article forgot to mention that the real breakthrough lies in the security of the transmission.

 

I guess the article forgot to mention that the real breakthrough lies in the security of the transmission.

It did mention it but a crack in transmission security is seldom the access point for breaching networks as classic communications security today is extremely secure and most methods will remain so even with powerful Quantum computers. The primary theoretical use for Quantum teleportation is the key exchange (key distribution schemes for encrypting classical information ) used in public encryption.

As Andris Nelsons, an eminent Latvian conductor, coaxed the quiet notes from the string section of the Leipzig Gewandhaus Orchestra, a woman in the balcony rustled a bag of gum, the Sydsvenskan newspaper reported. A young man sitting next to her glared a few times and then lost his patience. He snatched the bag from her and threw it onto the floor.

 

My dad was a pediatrician, and sometimes I think I could've been a pretty good surgeon, considering my fine motor skills.

But I very much prefer to deal with circuits and machines than with people.

Prof Kneebone says he has seen a decline in the manual dexterity of students over the past decade - which he says is a problem for surgeons, who need craftsmanship as well as academic knowledge.

the last time they did inspect the real kilogram, they found it is roughly five parts in 100 million heavier than all the working standards, which have been leaving behind a few atoms of metal every time they are put on scales

It's not a dead end. The article clearly states that:

The perfect sphere that will be used to redefine the kilogram in terms of the Planck constant in 2018 has been shown to consist of the purest silicon ever made.

The sphere is just a physical representation of the definition of the kilogram. The point is that now anyone anywhere can reproduce it with the right equipment.

One of the other SI unit being redefined is the Ampere.

But a person is the most incredible machine ever developed. Self replicating, self repairing. Try to duplicate that with transitors and motors.

Some very interesting tech is being developed for this purpose:

Despite its clarity, the new definition does not make it easy to realize the ampere. It requires extremely accurate counting of a staggeringly high number of individual electrons.

I would correct to say a machine with most incredible potential?

My mom was an elementary school teacher and she has been observing the motor skills in preschool children degrade year after year. We all think that tech will take over? But the situation is rediculous. What happens when software fails?

A number of societies when extinct becauee they lost ability to use early technology as they moved on to "higher" level... It is funny, but bwing a ludide is better for guaranteeing survival

Why would motor skills degrade? Seems with video games, hand eye coordination should be improving but aerobic capabilities decreasing.

Hand to eye coordination reflexes increases but good hand to brain mechanical skills are getting harder to find. One of my inputs with new hires is to look for people on also work on older cars or race real machines as a hobby.

But motor skills isn't being able to work on motors. Well you need good moor skills to work on motors.

My motor skills are poor. I have poor hand to eye coordination. And poor eyesight. On top of that I am dyslexic and I have hand tremors. Makes working in electronics a real challenge.

I have learned to deal with deal with the dyslexia. Actually it happened without me even doing anything. My brain sort of just figured out ii had a problem and installed a workaround on top of it. It doesn't always work but most times it does. Researchers were perplexed as to why I wasn't doing poorly in school. They knew I was seeing things backward but couldn't explain how I was able to recognize that. Sometimes I see the correction right before my eyes. it is really strange.

But out of all of my issues the one that is the most frustrating is the tremors. Soldering small parts can be really difficult. My brother is far worse off than I . But I don't think he does anything that requires detailed work.
