CRC periodic table, 1924

One more periodic table: from the 1924 CRC Handbook of Chemistry and Physics, which one of my ancestors picked up somewhere.


This periodic table has 79 elements, as opposed to the 117 on the current periodic table, 90 of which are naturally-occurring.

The familiar modern layout of the periodic table (as on my previous post) was developed by Glenn Seaborg in the 1940s as the trans-uranium elements were being created.

Element 112 — Copernicium

Copernicium (Cp) is found beneath mercury (Hg) on the periodic table

Element 112, a few atoms of which were created in Germany in 1996, finally has an official name. The new name is copernicium (symbol Cp), in honor of astronomer Nicolaus Copernicus (1473-1543). “Copernicium” replaces the temporary name ununbium (un=one, un=one, bi=two for 112, symbol Uub) that element 112 has had since it was created.

It is appropriate to refer to such elements as being created rather than discovered, as they do not exist in nature. The copernicium atoms where created by smashing zinc and lead nuclei together at high speeds. The copernicium-227 atoms created by this reaction decayed by alpha decay with a half life of about 240 microseconds.

I can see chemistry students confusing the symbols for Cu (copper) and Cp (copernicium).

Republicans for Environmental Protection — 10 critical issues

GreenElephantJim DiPeso of Republicans for Environmental Protection gives 10 Environmental Issues Republicans Should Champion.

  1. Climate change
  2. Energy security
  3. Clean energy
  4. Clean air
  5. Clean water
  6. Mountaintop removal coal mining
  7. Land and water conservation fund
  8. Wilderness
  9. Public lands
  10. Ocean stewardship

A few thoughts:

  • Some of these should be no-brainers, such as clean air, clean water, and ocean stewardship.
  • Several of these involve diversification of our energy portfolio to include more low-carbon energy sources. This diversification will be good for the economy, good for the environment, and good for our national security.
  • Even if you aren’t sure about climate change, you should acknowledge that it makes sense for us to move away from our current use-it-as-if-it-will-last-forever carbon energy economy. Better to plan now and ease into times of decreasing oil supplies than to have a “wait and see” attitude.
  • Some Republicans have a vision for stewardship of the environment, but a good number do not. Sadly, it is often the conservative Christians—heirs of the mandate to tend the garden—who are loudest in their opposition to environmental legislation.

Updates: job search, Best of The GeoChristian, Dr. Dino

I’m still looking for a job in the Earth sciences or GIS. I have a very strong possibility for an excellent position, but until it’s a sure thing I’ll keep on looking. Click here for a brief resume, or go to Ten reasons why you should hire me.

I’m working on compiling a list of what I think are my best posts, sorted by topic. Click on “Best of the GeoChristian” at the top of this page.

My January post Dr. Dino still in prison is still generating comments; up to 88 right now. (WorldNetDaily—the Christian source for conspiracy theories—reports that Dr. Dino is a victim of government persecution. I don’t think so.)

J. Gresham Machen on the age of the Earth

John Gresham Machen was a professor at Princeton Seminary in the early 1900s, and was founder of Westminster Theological Seminary in Philadelphia. He is best known as a defender of Christian orthodoxy in the face of rising theological liberalism in the churches of his day. Perhaps his most famous book was Christianity and Liberalism, in which he made the case that theological liberalism, with its de-emphasis on human sin and denials of the power of God, is not just a different form of Christianity, but is actually a rival of Christianity.

And he was another fundamentalist who had no problem with an old Earth. Here’s a quote from Machen’s The Christian View of Man:

The meaning of “day” in Gen 1 has been debated in the church at least since the days of Augustine. The literary form of the passage in its relation to other scriptures is important for its interpretation. Responsible Reformed theologians have differed as to whether Gen 1 teaches a young earth or allows for an old earth. While one of these interpretations must be mistaken, we believe that either position can be held by faithful Reformed people.
