Give Peace a Chance

Peace is an easy path to tread
Peace is where our fears are mislaid
Peace is beginning to restore
Peace for each man, woman and child
Peace for the troubled streets gone wild
Peace is for the old and the young
Peace in the end will overcome
Peace builds trust into a lifestyle
Peace is a friendly open hand
Peace is a place to understand
Peace in the end will overcome
Peace is for the old and the young
Peace is a legacy to leave
Peace is when we don't have to grieve
Peace is and end to all the hate
Peace is why we negotiate
Peace for all the victims of war

Paul McCann

 
 
All We Want Is Peace (Please)
 
 
 
 Peace, Peace, Please,
Please, Peace, Please,

There’s something we should do
That’s not been done
Something we can win
That’s not been won
Something we can SHOUT OUT
To end all their brutal war games
We Want Peace

Case for war was fake,
Don’t let it fade
More lives can be saved
Got to be brave
Something we can shout out,
We want peace, and we want it right now
Talking is Free

All we want is Peace
All we need is Peace
All we ask is Peace, Please
Peace is all we want

All we crave is Peace
All we miss is Peace
All we lack is Peace
Peace is all we want

Something we can ask,
Before it’s blown
Something we can grow
Before it’s grown
Small green shoots of Peace
To educate next infancy
Believe me

All we want is Peace
All we crave is Peace
All we wish is Peace, please

Peace is all we ask
It’s not a big task
Believe me
It’s easy.

All we want is Peace, All we want is Peace,
All we need is Peace, All we need is Peace.
Peace is all we want,
Peace is all we want
Peace is all we need,
Peace is all we need………………

    Until the middle of the 20th century the Earth's magnetism seemed to be a happy accident of nature. Too many factors had to fit just right--the fluid core of the Earth, its electrical condctivity and its motions, all had to satisfy the strict requirements of dynamo theory.

    That was before other planets in the solar system were visited and examined. Now we know that among those planets, only Venus lacks any magnetism. The planets differ greatly in size and properties, and their fields differ too. Yet they all seem to have dynamo fields, or (in the case of Mars and the Moon) have had them in the past.

  Jupiter
(bigger version)

Jupiter

    In early 1955, two young radio-astronomers started working with a cross-shaped antenna array of the Carnegie Institution's Department of Terrestrial Magnetism (DTM). The array stood on the north shore of the Potomac River (upstream from Washington, DC and slightly south of White's Ferry; more here) and could select signals from a narrow range of directions. Ken Franklin and Bernie Burke calibrated it using a known source, the Crab Nebula, then began surveying the surrounding sky.

One limitation, related to the failure of Blackett's theory, is that any electric circuit rotating like a solid body will not produce "dynamo currents." Even if part of the circuit follows the axis of rotation, and can therefore be viewed as non-rotating, solid rotation will not create any currents. An essential feature of the Faraday disk dynamo is that part of its circuit is outside the disk, not sharing its rotation.

    The rotation of the Sun around its axis, therefore, does not by itself contribute to its magnetism. What is important in this case is that the Sun does not rotate like a solid ball. Its equator has a shorter rotation period than higher latitudes-- about 25 days for the equator, 27 days for latitude 40 degrees (the Earth meanwhile moves some distance around the Sun, so from here the period seems to be 27 and 29 days). If Earth rotated that way, Florida (for instance) would soon pull away from the rest of the US, into the Atlantic Ocean. Such an uneven motion, deforming the surface, can drive a dynamo, and in the Sun's case, it is indeed believed to be the source of sunspot magnetism.

    Blackett's Proposal

        It is an uncanny fact that the Earth's magnetic axis is close to its rotation axis--that the magnetic poles, where the magnetic force points straight down, are quite close to the geographical ones. William Gilbert saw it as evidence that rotation and magnetism arose from the same source:

     

      "Diurnal motion is due to causes which have now to be sought, arising from magnetick vigour and from the confederated bodies."

        Gilbert thus believed the Earth rotated because it was magnetic. P.M. Blackett, who won the 1948 Nobel prize for his work on cosmic rays, seriously considered the opposite possibility--that the Earth was magnetic because it rotated around its axis. Blackett at one time suggested that perhaps a new universal phenomenon existed--that any rotating object was intrinsically magnetized.

        At first this did not seem such a wild idea. Electrons and protons, for instance, do have an intrinsic "spin" giving them properties like those of a rotating solid object, and they also have an intrinsic magnetization, making them tiny magnets, lined-up with their spin axes. In ordinary materials, such atomic magnets point in all possible directions, so that their effects cancel.

     



    But concerning the Earth, Blackett guessed wrong. Experiments with spinning objects, which by his theory should have produced measurable magnetization, showed none. Later observations also showed that during the last tens of millions of years, the magnetic polarity of the Earth reversed many times, something that Blackett's prediction would never allow.

      The core of the Earth

The Earth's Core

    The way earthquake waves spread tells us that the Earth has at its center a dense liquid core, of about 1/2 the radius of the Earth--and inside that, a solid inner core. It is widely believed this core is made up of molten iron, perhaps mixed with nickel and sulfur. The density seems appropriate, and iron, which among all elements has the most stable nucleus, is abundant in the universe. It concentrated in the Earth's core because it is heavy--the same reason that, when it is extracted from its ores, it sinks to the bottom of the blast furnace.     Energy is the currency with which most processes in nature must be paid for. The Earth's magnetism is no exception, and its energy seemes to come from fluid motions in the Earth's core, from circulating flows that help get rid of heat produced there. In a similar way, our weather is driven by circulating air flows that help cool the ground, where much of sunlight is absorbed.

    Scientists are still not sure about what provides the heat in the Earth's core. It might come from some of the iron becoming solid and joining the inner core, or perhaps it is generated by radioactivity, like the heat of the Earth's crust. The flows are very slow, and the energy involved is just a tiny part of the total heat energy contained in the core.

The flows are very slow, and the energy involved is just a tiny part of the total heat energy contained in the core.

    So the molten metal is believed to be circulating. By moving through the existing magnetic field, it creates a system of electric currents, spread out through the core, somewhat like Faraday's disk dynamo, discussed earlier. Currents create a magnetic field--a distribution of magnetic forces--and the essence of the self-sustaining dynamo problem is to find solutions such that the resulting magnetic field is also the input field required for generating the current in the first place.

    Actually, that is only the lowest level of the problem, in which one is free to prescribe the motions. To solve the full problem, we also need information about the heat sources, and these sources must be able to drive motions which also solve the dynamo problem.

    Such problems are not easy. They involve intricate mathematics and are not yet fully solved. Only the roughest ideas in their solutions can be outlined here.
