From a science writer: Any scientist couples out there?

I am a science and nature writer based in Arizona, U.S. I'm currently writing nature and health magazine articles and conducting research for a book. I'm looking for scientist/researcher "teams" in which a husband and wife work together. I am researching it for a possible book-length work, and would like to touch upon husband/wife teams historically as well as several today. Are there any collaborations like this among you -- in which it's more than one partner supporting the other; it's a life passion for you both? I'm making sure to include historic examples like mathematicians Julia Bowman and Raphael Robinson, and the Curie family of course; so cite other noteworthy examples as well, but I'd really like to know what it's like for scientist couples today. Thanks for your time. Feel free to reply here or e-mail me at [email protected]

The Case Against God: God's Nature

I've heard often that it is impossible to prove or disprove the existence of God in any way. While this may be true simply because we have a hard time proving anything either way, we can show that God does not exist to a high degree of certainty. Many of the examples and explanations I offer borrow heavily from George Smiths The Case Against God and Richard Dawkins' The God Delusion. Firstly, I would like to examine, and then refute, the nature of God. God is usually defined as having these three major attributes, they are his "nature." 1. *_Omnipotence_*-God is all powerful. He can do anything, and there are no obstacles to his will. He can do all. 2. *_Omniscience_*-God knows everything. Past, present, and future. He can see you when you're sleeping and knows "every hair on your head." 3. *_Omnibenevolence_*-God is all good. He is the most perfect and morally just being in existence. He does no evil.

  • _Omnipotence_*
In a nutshell, Omnipotence is power without limitation. To quote modern Christian dogma, "nothing is impossible with God." Unfortunately for the big guy, Omnipotence creates some serious problems. By being all powerful, can God create a square circle? Can God make a computer turn into a fruit bat and do the macarrana? If not, he is not all powerful. A square circle does not exist because, by its very nature, it is a logical contradiction. If God cannot create such a contradiction, he is a contradiction because he denies his own nature, just like a square circle, and just like a square circle, he does not exist. And if he can do the impossible, he himself is logically impossible, and therefore, does not exist. A theist may counter this proof of God's nonexistence by saying that God is not truly omnipotent, he is only omnipotent in the sense that he can do anything we can imagine. He can, for instance, make a computer turn into a fruit bat. But God would still be asking a computer to deny its nature and do something that is not scientifically possible. And if God can defy science, then an rational thought about the world around us in pointless. But an omnipotent being defies logic even past that. If a being is truly omnipotent, there can be no obstacles to his power. He can make anything happen at any time, without anything being able to stop him. If God's will is sufficient to make anything happen at any time, God does not need a means to accomplish anything because the use of means to meet an end shows that the user of the means has limited power. If God uses any means, such as an angel to deliver his word, he is not omnipotent, and therefore, does not exist as he is known to us. Which means that God cannot act, because acting in any way would require the usage of means to accomplish his will. If God acts, he cannot be omnipotent, and does not exist. Looking farther into the nature of God, we can see that he has no purpose, because the possession of purpose implies unfulfilled desires or goals. If God has unfulfilled desires, he is not omnipotent, and does not exist. So now, if we visualize God, we must see a being who has an unfounded power to do anything, who does not employ means, does not act, and has no purpose. _*Omniscience*_ The Christian God is said to be omniscient, he has knowledge without limits. He sees and hears everything. He knows everything that has ever happened and ever will. The first issue that contradicts Christian dogma outside of Calvinism (what a horrible outlook on life!) is the evaporation of free will. According to modern Christianity, we have the choice to do what we wish. But if God knows the future with infallible certainty, the future has already been decided, we we do not posses free will. I'm certainly not going to waste time on predestination, it has to be one of the most ludicrous philosophies I have ever heard of. Another problem with omniscience is that it contradicts omnipotence. If God knows the future with complete certainty, he cannot change it. If he can, then he does not know the future with utmost certainty, and he is not omniscient. This raises another problem, if God knows the future, does he posses free will? If he knows his future actions, how are they free? And if God does not make his own choices, he is not omnipotent, etc. Also, for knowledge to be possessed by any entity, that knowledge must be obtained through observation. And if knowledge is obtained by God, he must not have had the knowledge at some point, which would mean his is not omniscient. So, for God to possess knowledge that was not obtained or observed, he does not possess knowledge in any sense of the word, and omniscience loses all meaning. _*Omnibenevolence*_ The notion that God is all-good creates some serious issues for the Christian. For one thing, the God of the Bible is one of the most morally corrupt and detestable characters in all of fiction. He ordered the killings of thousands and personally killed thousands, including innocent children. The "word of God" found in the Bible is tainted with the blood of hundreds of thousands of innocents who were recorded as murdered by the God of the Hebrews and of the Bible. Many modern theologians argue that the God of the Old Testament is different, he changed for The New Testament. Unfortunately, the God of the New Testament can be considered much worse then the old one. At least the old God punished sinners and innocents by killing them, the new, just God sentences them to agony and suffering for all eternity. It is very difficult for the modern Christian to explain Jesus' message and the idea of a merciful God that those who insult God's might will burn in torturous flame forever. And this view of the evil God is enhanced by the attributes of omnipotence and omniscience.* Because God knows the future, he knows exactly what we are to do in our lives, so he creates multitudes of people who have no purpose but to burn in hell. * Also, why would God create hell, unless he finds pleasure in watching his creations suffer? There is no reason for a hell for an omnipotent God. The problems of Omnibenevolence extend into the philosophical. For God to be all good, we assume that he never commits evil. We also assume that, because he is omnipotent, he has the ability to commit evil, but always chooses good. So, why is there evil in God's creation? If God knows that there is evil, can prevent it, and chooses not to, he is not omnibenevolent. If you observed a little old lady being beaten, and had the ability to prevent it, wouldn't you? If so, you are morally above God. Ignoring that fact, most Christians proclaim that God did not create evil, but gave us a choice. We brought evil into the world. But this contradicts God's omnipotence. If God is omnipotent, his will is fulfilled without conflict, nothing can stop it. So, if God is omnipotent, we must assume that he wants evil in the world, and any evil that exists is exactly what he wants. And if God knows all, we have to assume that he created evil men with full knowledge of what they would do, and that he desired for those atrocities to occur. The Christian may argue that these evil events are for the greater good. Unfortunately, this in no way reduces the moral incorrectness of these actions. Just because God may save the child that walked into the road by wrecking and killing the driver of the car that would have hit him does not mean that killing that driver is ok. It is still wrong. The same can be applied to natural disasters. Why does God inflict these tragedies? The Christian may argue that they are merely part of his plan to make things better, but, like the murder of the driver, that does not make the thousands of lives taken by God in a disaster "a ok." If the three main attributes of God are so obviously in contradiction with each other and with Christian dogma, the God of Christianity can be made to dissipate in a puff of logic.

Terra Preta Data bases, Web Sites, Mail List and Blogs

Terra Preta Web Site at; Terra Preta | Intentional use of charcoal in soil (http://terrapreta.bioenergylists.org/?q=node) It has been immensely gratifying to see all the major players join the mail list , Cornell folks, T. Beer of Kings Ford Charcoal, M-Roots guys(fungus), chemical engineers, Dr. Danny Day of G. I. T. , Dr. Antel of U. of H., Several Virginia Tech folks and many others who's back round I don't know have joined. Registration has averaged one or two per day over the last few weeks. ABOUT; Welcome to the Website for the Terra Preta Discussion List: [email protected] This new addition ("Terra Preta") to the suite of bioenergy lists is going to strive to be the primary world web location for technical discussions on a new possible important use for biomass (that is described below). We have chosen the term "Terra Preta" (hereafter TP to save typing) as most of your search hits on these words will return valuable information. The term fits well-enough with the five other biomass-oriented discussion lists (bioenergy, stoves, gasification, bioconversion, anaerobic digestion) – all of which have the world-wide audience that we hope the Portuguese words for “Black Earth” will also connote. However, the topics to be discussed here are also known as "biochar" and "agrichar". Still other names will certainly appear and perhaps cause us to rename this site -which we are starting this day so that there is a convenient single site for dialog of the type found on the other "bioenergylists". I have agreed to be the primary Terra Preta list coordinator at the request of Tom Miles and Ron Larson. Tom has been in this biomass discussion-list business since 1994 (mostly paying for everything out of his own pocket – Thanks Tom). I feel comfortable taking on this task because of the quality of Tom’s work and because the quality of the many list discussions have been apparent to me for many years. Ron and I have communicated a bit on Terra Preta topics for several months. I also agreed to take on this task because of words of encouragement that came out of Ron’s six-seven years as the first Coordinator of the successful “Stoves” list for which Tom has recently been the primary Coordinator. A recent TP paper by Ron from “Solar Today” magazine has been up on the “gasification” website for a few months –and now is as well on the TP web site. Ron reports that the TP topic was under discussion on “stoves” about 4 years ago – because of Ron’s own continuing interest in charcoal-making. One (two?) of my own recent internet letters is also up now on our own TP site– courtesy of Ron and Tom. The third Coordinator is >>>>>> What does “TP” denote? By this term, I mean the intentional placement of charcoal in soil. Surprisingly, it is now becoming apparent that doubling and tripling of soil productivity can result. Surprising also that TP’s invention and proof of productivity improvements dates back several thousand years in Brazil. We hope that soil scientists around the world will contribute to this list with soil answers needed by those others of us interested in a very different aspect of TP soils. That different aspect is that the sequestered charcoal is taking CO2 out of the atmosphere – apparently at a lower cost than any other means of doing so. Hopefully, a large percentage of submissions to this new list will concentrate on TP’s climate benefits (and costs). Lastly, on this list especially we expect to see a lot on production of charcoal – the third main aspect of TP needing your input. We expect some reading this to be skeptical that a fuel that worldwide is more popular than wood should be dumped in the ground at a time when we are hoping biomass can slowly replace our dwindling fossil fuels. Making this case, or disproving it, is the purpose of this discussion list. Let us hear from you. My job, which Tom and Ron say is easy, is to keep us on topic. They have committed to supply me a whole slew of TP questions that they feel are not yet well enough answered. Let us all hear your questions – and answers.

The technique is called "Terra Preta," Portuguese for "black earth." It is not new. It was invented by an ancient agricultural civilization in the Amazon that made charcoal and buried it the soil. The charcoal absorbs and holds nutrients from manure and supports beneficial microbes. Some of these fertile soils are more than 1000 years old.

Brain works more chaotically than previously thought

The brain appears to process information more chaotically than has long been assumed. This is demonstrated by a new study conducted by scientists at the University of Bonn. The passing on of information from neuron to neuron does not, they show, occur exclusively at the synapses, i.e. the junctions between the nerve cell extensions. Rather, it seems that the neurons release their chemical messengers along the entire length of these extensions and, in this way, excite the neighbouring cells.

Viking navigation hypothesis under foggy and cloudy skies requires more light

While history portrays the Vikings as skillful masters of the sea, sailing treacherous routes in the northern Atlantic Ocean during the 10th-13th centuries, just how much knowledge, technology and ability they possessed is debatable. One theory claims that the Vikings could navigate even on cloudy or foggy days using skylight polarization, which would not only require specific atmospheric conditions, but technology beyond anything known in Viking culture.

Hello from the swamp

Hi everyone. I like math and Astronomy and a few more things. Just recently ordered a telescope. Planning to attend my first star party once I figure out how to use it. My background is Chemistry and Biology but went straight into information technology out of college. I'm a pretty good programmer and like using Mathematica. I've done a lot of work with non-linear dynamics, emergence, chaos, strange attractors, you know that stuff. What else? Into health and fitness, the biologist in me I suppose. Biochemistry helps I think but the book are really big. Let's see, what else? Suppose I'm into evolution or use to be anyway. Couldn't finish reading "Origin of Species" though: too dry and jam-packed with too much data. Did finish "Passions of the Mind" though. Think I did anyway. Oh yea, interested in brain science too. I forgot that one. Dr. Phil too!
