Agreed. That volleyball thingy...

[tsomer]

Pay me enough and I’ll make this article into a comic book.

You’ll laugh; you’ll cry a little too, but you’ll never look at things the same way again.

I understood "It's basically a possible way to store".

After that you lost me.

[Red Badger]

I’ll just boil it down to this, for you, Laz:

More porn. Faster porn....................

electrons at the boundary of the laser spot will travel clockwise or counterclockwise depending on their spin

So if they are spinning clockwise, they'll travel clockwise? And vice-versa? What's so hard about that?

It’s because of the amount of studying they do. It is very much part of their culture, immense pressure to do well so they study hard.

When it comes to competitive efficiency in business, being able to make fast decisions, they don’t do so well. Endless chains of approvals, it takes forever to get agreements.

Non-volatile storage like a high density DVD? How long does the “valley” hold its state?

[Lazamataz]

Ok thanks, that was understandable.

[Red Badger]

Unknown. More research, of course.................

I’ve visited Nanyang and have done some courses for faculty there. Impressive institution.

It’s because of the amount of studying they do. It is very much part of their culture, immense pressure to do well so they study hard. I think you are correct as far as math and science. I saw that with one of my kid's Oriental friends from a few years back. He was quite smart and I think his parents were quite strict as far his homework...even over the summer. I wonder why a lot of them are so good at drawing/art? That was another thing I noticed.

Stability is important. Especially across temperature and environmental conditions.

[RaceBannon]

I didnt understand that to be about memory, but electron movement, sort of like a buss, with insulation possible between, so smaller devices can have flow and reduced size to get the same effect from a much smaller device

[Red Badger]

This valley degree of freedom, or valley index, has a potential to be used for carrying information like in a computer. Transistors nowadays are reaching a fundamental size limit that is either difficult or too expensive to overcome, and monolayer materials like tungsten disulfide may have the capability to carry the next generation of electronics, Sie suggests.

[Red Badger]

One of the principles of a possible quantum computer would be to utilize the electron spin direction as a 1 or a 0 for massive data manipulation...........................

I had lunch with a friend of mine from Taiwan today. They are trying to shield their 11 year old daughter from some of the pressure. But they say the peer pressure from other Asian kids in the school is so intense that the parents don’t even have to apply the pressure! This is a heavily Chinese area in Fremont, CA.

[beaversmom]

Definitely pluses and minues to that way of thinking. Hard on kids, though, that can’t measure up.

[ProtectOurFreedom]

Yes, extremely hard. The kids seem to miss out on a lot of childhood. Worst case they commit suicide.
