Funny story about the sun needed..
Hello,
I am giving a lunch-and-learn about the sun this Thursday and would like, as part of my presentation, to tell a funny story about the sun. Jokes about solar magnetism or nuclear fusion or neutrino studies or funny solar science history anecdotes would work too. If anybody could post any any stories of this kind, they would be very much appreciated. If you know a link to a good cartoon, post that. The audience is mainly non-scientific although they probably already heard the one about the not-too-swift solar-explorer-astronauts planning a landing on the sun at night when it is dark and cool. Thanks, Michael |

Thanks, Michael One funny story is that many astronomers think there is some kind of dynamo inside the Sun which produces magnetic fields so powerful that they can expel billions of tonnes of matter into space and have field lines (!) that can stretch, twist and break with explosive force. The "lines" are an imaginary math concept which Faraday proposed to indicate the strength and direction of the magnetic field. Fortunately the "magnetic lines" in our large rotating electrical machinery do not behave in this peculiar fashion. If you would like to mention a more rational explanation of solar characteristics see http:www.brox1.demon.co.uk/sun2.htm and/or (illustrated) http:/www.brox1.demon.co.uk/solar/Solarphysics.htm I hope you have a good lunch and an appreciative audience. -- Eric Crew |

Hi Eric,
I read with much interest your page proposing an electrical rather than magnetic origin for "such as sunspots, magnetic fields, flares, prominences, periodic variations, neutrinos, the apparent high temperature of the corona and the influences on Earth's climate" -- neutrinos no less... http://www.brox1.demon.co.uk/solar/Solarphysics.htm Your L. Körtvelyéssy writes "The heat of fusion in the solar core causes its atomic particles to attain high velocities, so that there is a continuous current flow along the temperature gradient from core to surface. Electrons are predominant in this flow as they have well over 1000 times less mass than a proton. This gives the surface of the Sun a layer of negative charge and the core an increasing positive charge. A continuous solar wind is ejected from the surface and periodically the positive charge on the core exceeds the breakdown value, causing planet-sized pieces to break away and be expelled towards the surface. " How does he or you explain the magnetograms showing strong north and south, or positive and negative magnetic fields inside of and around sunspots? I don't see how rejecting magnetism eliminates more problems than it solves. Michael I heard one funny story though -- though not about the sun. Question: What's the easiest way to observe Doppler's effect optically (not accoustically) in one's everyday life ? Answer: Go out in the evening and look at the cars. Their lights are white or yellow when they approach, but they are red when they are moving away of you. (from Andrzej Kudlicki) |

Körtvelyéssy writes "... A continuous solar wind is ejected from the surface ... " Note that in the book, this is further emphasised. According to Körtvelyéssy the solar wind carries away electrons from the surface in vastly greater numbers than the more massive positively charged ions. The result is a net current of -10^14A leaving the Sun continuously (Fig I.4, page 21). The surface of the Sun is a conductive plasma so we can model it as an isolated conductive sphe http://hyperphysics.phy-astr.gsu.edu...capsph.html#c2 For a radius of 6.96e8m, the capacitance of the Sun is 0.077 Farad. The potential would therefore rise at 12.9 V/s per Amp or over 10^15 Volts per second. Körtvelyéssy claims the electrons are emitted at 750km/s and I'll leave the interested reader to calculate how long it would take to build up sufficient field outside the Sun to stop the flow. Since the current is a flow of electrons, the Sun is of course positively charged. However, in chapter 2.02 and 2.03, he describes how the _negatively_ charged Sun attracts _positively_ charged cosmic rays "from lightweeks away". A similar problem applies to the model of the core and surface which he claims aree separated by an _insulating_ plasma so would behave as a spherical capacitor: http://hyperphysics.phy-astr.gsu.edu...ic/capsph.html The book is beautifully produced and I must thank Dr Körtvelyéssy for the copy, but I'm afraid that the electrostatics it contains is badly flawed.

It's comparable to his claim that I paraphrase 'thermal electrons leaving the sun's core are repelled further by the electrons behind them". The core of the claim is that since electrons are 1800 times lighter than protons they are able to go much faster and can escape. The fact that their motion is 1800 times more affected by any force is ignored. Oh, I almost forgot; there's a claim that I just couldn't make any sense of which seemed to say that "the positive charge on a hydrogen ion takes longer to be neutralised in recombination than the negative charge on the electron". A wonderful site. |

George Dear George We have discussed this at length before and it seems to me that your calculations do not account for the increasing number of observations about the occurrence of electrical discharge jets in astronomy. This indicates that your analysis must be much too simple. You did not dispute that the 'generally accepted miraculous magnetism' theory cannot explain the observations and you still criticise the 'electrical discharge' theory published in refereed journals by C E R Bruce and myself, which have been subsequently strongly supported by the work of Körtvelyéssy. Are you still unable to suggest another theory which does give a reasonable explanation for the evidence? -- Eric Crew |

Probably too late now, but here it is anyway. When Ray Davis started his original solar neutrino experiment, he bought several thousand gallons of cleaning fluid to fill the detector. I've been told that shortly afterwards, he was overwhelmed by sales people wanting to sell him vast quantities of coat hangers. -- Steve Willner Phone 617-495-7123 Cambridge, MA 02138 USA (Please email your reply if you want to be sure I see it; include a valid Reply-To address to receive an acknowledgement.
