Thread: 30 May 2008: Centenary Hannes Alfvén's birth

Today marks the 100th anniversary of the birth of Swedish scientist Hannes Alfvén. He is sometimes known as one of the founding fathers of the field of plasma science, but while his work culminated in being awarded the 1970 Nobel Prize for physics, he considered himself something of a maverick and dissident, a view shared by some scientists.

I think he was part of the problem not the solution. Adios.

Alfvén or De, and can you elaborate?

Happy Birthday Hannes

You could conclude from that letter that he and Isaac Asimov did to much acid in the sixties.

He's just stating a known fact, it is not possible to create the amount of anti matter required for anything significant in military applications. for example making an anti matter bomb just isn't feaseable unless you predict a war a long way in the future and you prepare very early.

There is no such thing as anti-matter. You have your anti-freeze. You have anti-skid surfaces. But no anti-matter. If you are aboard the Star Ship Enterprise, with Capt. Kirk, then you have anti-matter.

But in real life there is no anti-matter.

Not understanding how electrons can be instantly accelerated, to higher speeds. Will cause these kinds of phony particle creations.

By the way did you know that acceleration just means a change in speed technically. It does not mean to go faster or slower. It could mean either one. At least when it was first conceived. It appears that more modern texts omit the change in velocity definition. And just state being able to go faster.

Some physics definitions still use the older definition meaning a change in velocity. Not faster or slower.

When you are selling old cars it comes in handy. You can say boy when you hit that accelerator, that car really accelerates. Even if it just stalls out. Ha-ha.

They can create anti-matter and they have done it. As i have said before, anything whichcannot be explained with your theories just doesn't exist in your world. Even if its proven you still deny it.

Acceleration is rate of change in velocity so yes it could be speeding up or slowing down

Generally, it could also simply mean a change in the direction of the velocity (time derivative of the velocity vector).

So, how would you call a particle that has the same properties like an electron, but a positive electric charge?

There is no positive charge. Just more or less repulsion. We unfortunately now call the repulsive, electron motive force, that pushes electrons, and matter away. Negative.

That is what the confusion is, when young people go to learn about it. It screws them up forever.

I was fortunate to grow up in a family that worked with electron beams, anode rays and cathode rays. They had to know which way everything was going. And how it was fed and by what. I then started to do the same and I had to know.

But when I go through life I am forever walking up to people handling and dealing with mega power. And they really don't know, how it works. They just know that you have to do certain things or they blow up. But the basic understanding is not known to them. That seems a little Bolshevik to me.

Same is true with chip people. They have to do a double, double take, to simply stat which way everything is going. They speak cautiously as if they are on thin ice. And with me they are.

The problem is that my understating simply explains disintegration and positive acceleration. So that something that existed can easily be broken down into its basic formation, electrons, and disappear harmlessly through glass, metal, stone, and insulators.

You have to take a really good look at the basics of electricity. Like Benjamin Franklin did, before you go onto, anything else. From there everything else is cake.
