A little food for thought. Metal can learn?

Nickel oxide’s ability to learn could fuel new AI fields

For over half a century, neuroscientists have studied sea slugs to understand basic animal learning. Two fundamental concepts of learning are habituation and sensitization. Habituation occurs when an organism’s response to a repeated stimulus continuously decreases.

When researchers first touch a sea slug, its gills retract. But the more they touch the slug, the less it retracts its gills. Sensitization is an organism’s extreme reaction to a harmful or unexpected stimulus. If researchers then shock a sea slug, it will retract its gills much more dramatically than when it was merely touched. This is sensitization.

Nickel oxide has features that are strikingly similar to this learning behavior. Instead of gills retracting, we measured the change in electrical conductivity of the material. The stimulus, instead of a finger poke, was repeatedly alternating the environment of the nickel oxide between normal air and hydrogen gas.

Off to B'ham to visit with my 90 YO Mom. Haven't seen her much over the last couple of years.

Hope you all have a wonderful day!
I like singing this one with my somewhat altered verses...

I saw three ships come sailing in

On Christmas Day, on Christmas Day;

I saw three ships come sailing in

On Christmas Day in the morning.

Pray, wither sailed those ships all three,

On Christmas Day, on Christmas Day;

Pray, wither sailed those ships all three,

On Christmas Day in the morning.

O they sailed into Bethlehem,

On Christmas Day, on Christmas Day;

O they sailed into Bethlehem,

On Christmas Day in the morning.

And all the bells on earth shall ring,

On Christmas Day, on Christmas Day;

And all the bells on earth shall ring,

On Christmas Day in the morning.

And all the souls on earth shall sing,

On Christmas Day, on Christmas Day;

And all the souls on earth shall sing,

On Christmas Day in the morning.

Then let us all rejoice again,

On Christmas Day, on Christmas Day;

Then let us all rejoice again,

On Christmas Day in the morning

I saw three ships come sailing in

On Christmas Day, on Christmas Day;

I saw three ships come sailing in

On Christmas Day in the morning.

I saw three ships come sailing in

On Christmas Day, on Christmas Day;

I saw three ships come sailing in

On Christmas Day in the morning.

As a seagoing country and ascending maritime power, they just couldn't imagine getting to anywhere else by any other way than by sea. Smile

There is no justice. There can be no peace.

Merry Christmas. Nitenol, an alloy, have been famous as the "memory metal" since I was a kid, but in a completely different fashion. Thanks for the information and food for thought.

We struggled but got this 9 + footer into the house this year. My spouse is like a kid in a candy store. We have so many ornaments from over the years. This tree was big enough to hang many of them, at least 300, and she knows where each one came from. Amazing.

I don’t have room for my little tree, but have put out my Peanuts nativity scene and of course the little Charlie Brown tree.
