    Earth at Night


    NASA has a composite picture of the earth at night.

    Note the concentrations of light! I wonder how far out the lights would be visible to the naked eye.

    Can you find your favorite country or city? Surprisingly, city lights make this task quite possible. Human-made lights highlight particularly developed or populated areas of the Earth’s surface, including the seaboards of Europe, the eastern United States, and Japan. Many large cities are located near rivers or oceans so that they can exchange goods cheaply by boat. Particularly dark areas include the central parts of South America, Africa, Asia, and Australia. The above image is actually a composite of hundreds of pictures made by the orbiting DMSP satellites.

    I also like their astronomy picture of the day.

    Reality will not be overthrown


    The United States has, until now, been a (if not "the") world leader in scientific research and the development of technologies. This has been the backbone of public policies that navigate reality, and it has brought us our highish standard of living and our economy of relative priviledge. But I think we’re on the way out of that role. When ideologies replace knowledge, it is always the people who pay.

    Certain fundamentalist groups, suspicious of all intellectuals, "eggheads," and independent thought, have moved us even further into a state of socio-pathology. Their effects on public policy, public higher education, biomedical research, family planning and sex education, environmental issues, the arts and humanities, freedom of inquiry, and even research funding for the common good are monumental, and I suspect that these effects will continue to feed into the sucking vortex of disaster created the skewed priorities of the neocons and crony corporatists.

    This administration puts political interests above our well-being as a people. Knowledge and expertise has been pushed aside in favor of unqualified appointments (or those with clear conflicts of interest), the dissolution of advisory committees, and even censorship and suppression of reports from the government’s own scientists.

    Across the board, "intelligence" (I use the term in its double meaning) is disregarded unless it supports a conclusion desired by power. There is nothing more deadly to truth than this. I believe such disregard is a substantial security risk that presents a clear and present danger to the American people. We are becoming a danger to ourselves as well as to others. There is still room in our current system for things to change. I hope that the momentum for such change is growing, and I hope that real leaders will emerge – soonest – in this nation’s time of need.

    Flying Spaghetti Monster


    The Flying Spaghetti Monster made it into the Wikipedia, nice!

    The Flying Spaghetti Monster is the deity of a religion, known as Flying Spaghetti Monsterism, started on the Internet by Bobby Henderson as a parody of the decision by the Kansas State Board of Education to allow intelligent design to be taught in science classes alongside evolution. Henderson submitted an open letter to the Kansas Board of Education demanding that the Flying Spaghetti Monster be given equal time in classrooms along with Christian and all other creation myths. The “religion” has since become an Internet phenomenon garnering many followers preaching the word of their “noodly master” as the One True Religion.

    The doctrine of this emergent religious movement centers on the belief that the Universe was created by a Flying Spaghetti Monster and mandates that His followers shall wear full pirate regalia to ward off natural disasters caused by the decline in numbers of pirates.

    Shiver me timbers and ahoy! Ra-men.

    Navigating the Minefield of Teaching Evolution


    Understanding Evolution

    This is a very good introduction to evolution, intended to help teachers navigate through the current minefield.

    “Do you believe in evolution?” is a question often asked of biology teachers by their puzzled students. The answer is, “No, I accept the fact that the Earth is very old and life has changed over billions of years because that is what the evidence tells us.” Science is not about belief—it is about making inferences based on evidence.

    The alleged incompatibility of religion and evolution has been used as a way of persuading people to deny the history of the Earth. The following misconception is dependent on a misunderstanding of the functions of both science and religion.

    Religion and science (evolution) are very different things. In science (as in science class), only natural causes are used to explain natural phenomena, while religion deals with beliefs that are beyond the natural world.

    The misconception that one has to choose between science and religion is divisive. Most Christian and Jewish religious groups have no conflict with the theory of evolution or other scientific findings. In fact, many religious people, including theologians, feel that a deeper understanding of nature actually enriches their faith. Moreover, in the scientific community there are thousands of scientists who are devoutly religious and also accept evolution.

    The National Center for Science Education has statements of support from several religious organizations, who affirm the constitutional separation of church and state as supportive of religious freedom, and who support the teaching of evolutionary theories knowing that it doesn’t threaten faith.

    Intelligent Design a Boondoggle


    In a roundtable interview with reporters from five Texas newspapers President Bush said yesterday that he believes schools should discuss “intelligent design” alongside evolution when teaching students about the creation of life.

    No problem. Just don’t ask science teachers to teach it. Teach it in religion classes, not alongside evolutionary theories in biology class. The principle of selection: what lives to reproduce passes on its genes. There are discussions about different theories within the science of evolution – debate about catastrophic events, punctuated and gradual evolution, the big bang. Much of science has latent mysterious content – read up on string theory or strange attractors, for example. However, renaming “creationism” as “intelligent design” doesn’t make it science. What are you going to teach? Bible verses? In any case, there are lots of creation stories – you’d then have to teach them all, not just the Genesis account. Wouldn’t it be better to leave that to families and the worship centers of the different religions? Why would the public school system be teaching Judeo-Christianity?

    Intelligent design refers to the theory that “unspecified intelligent causes” (i.e. God the Father) are responsible for the origin of the universe and of life in all its diversity – well anyway, the life we know, which is based on carbon.

    Don’t laugh – these pseudochristics are serious! They are already anti-intellectual, anti-science. They want followers, not thinkers.

    The House Subcommittee on Basic Education in Pennsylvania heard testimony Monday on a bill that would allow local school boards to mandate that science lessons include intelligent design. The legislation is sponsored by only a dozen lawmakers. A federal judge will consider the issue this fall, when a lawsuit against the Dover Area School District is scheduled to go to trial. The suit alleges that the school board violated the constitutional separation of church and state when it voted in October to require ninth-grade students to hear about intelligent design during biology class.

    Of course, here in Georgia, the infamous Cobb Country had big stickers in all the science textbooks proclaiming that evolution is just a theory until a federal judge in Atlanta finally put the nix on it in January saying the disclaimers are an unconstitutional endorsement of religion. The stickers were added after more than 2,000 parents complained that the textbooks presented evolution as fact, without mentioning rival ideas about the beginnings of life, such as the biblical story of creation. Six parents and the American Civil Liberties Union then sued, contending the disclaimers violated the separation of church and state and unfairly singled out evolution from thousands of other scientific theories as suspect. The judge ruled that “While evolution is subject to criticism, particularly with respect to the mechanism by which it occurred, the sticker misleads students regarding the significance and value of evolution in the scientific community.” “By denigrating evolution, the school board appears to be endorsing the well-known prevailing alternative theory, creationism or variations thereof.” Last year, Georgia’s education chief proposed a science curriculum that dropped the word “evolution” in favor of “changes over time.” The idea was dropped amid protests from teachers.

    This focus on the new creationism is very clever. If they get religion taught as science they gain more control over the children (get ‘em while they’re young). Such children will be unable to distinguish between science and religion, but as Bush himself shows, many of our kids are impervious to the very best education. We may lose out in the science and technology wars of the future, but hey, we’re going down anyway with the gradual destruction of the public school system that helped us rise. If the fight fails, they still motivate their fearful, hateful base -energizing them with that ole God is on our side bull at a time when people are getting less enthused about Iraq, oil/gas prices, and so on. Now that’s strategic politics.

    One question, though – if you believe in creationism (and that’s what this is), then you probably also believe that God placed humans in the position of the stewards of the earth. How is it that the same group of people who advocate for creationism are first in line to let corporations pollute? Where are their environmental concerns? Some stewards.

    What possible joint interest could a real Christian have with the death and power policies of this administration? Believers are so easily manipulated – don’t you remember that warning about false prophets?
