It is an amazing world! Here's the cover of the April 2007 issue of Geology, published by the Geological Society of America. These crystals of gypsum were discovered in a cave at a lead-silver-zinc mine 100 km from Chihuahua, Mexico. The crystals are up to 11 meters (36 feet) long, and were submerged in water …
Earthquakes and the End Times
This item was originally posted on April 18, 2006 to commemorate the 100th anniversary of the great San Francisco Earthquake of 1906. It is now part of my blog recycling program. Because I have more people reading The Earth is Not Flat! now than I did a year ago, I will occasionally go back and …
Moons of the outer solar system — Death Star in orbit around Saturn
Saturn's moon Mimas resembles the Death Star of the Star Wars movies. This is a coincidence, as the images of Mimas were taken after the first Star Wars movie came out. Grace and Peace
Moons of the outer solar system
My middle school students will be working on reports on the moons of the outer solar system this week. When I was in middle school, the gas giants had what we thought were a lot of moons, but that number has greatly increased as telescopes have improved and probes have been sent to the outer …
Yippee!!!
I had a busy week at school, with several 12-14 hour days. I preached this morning at our church, Biserica Trinitatea (Trinity church), and preparation for that consumed the rest of my life. Now I have a few hours of freedom (I think). Yippee!!! Grace and Peace
Moons of the outer solar system — images
Here are a few of my favorite images of the moons of the gas giant planets, all taken by the various probes that have gone through the outer solar system in the past thirty years: Io, the innermost of Jupiter's four large moons, and the body in the solar system that is the most volcanically …
Simple Cells?

Mars World Wind
I've been enjoying using NASA's WorldWind software to help my 7th/8th grade Physical Science students understand the solar system a little better. Mars especially has an amazing variety of features and landforms formed by tectonic events, meteorites, running water, groundwater, ice, and wind. (I've written about Mars WorldWind before, but I'm having so much fun …
A New Hypothesis Regarding the Ridges and Grooves on Jupiter’s Moon Europa
Jupiter's moon Europa is covered with grooves and ridges. The common hypothesis is that the crust of Europa is composed of thick sheets of ice which float on a liquid water layer deeper in the satellite. As these plates of ice move around, ridges and cracks form. NASA/Astronomy Picture of the Day This is a …

Earth as art
"And God saw everything that he had made, and behold, it was very good." -- Genesis 1:31 I'll let these images from NASA's Earth As Art site speak of the beauty and goodness of God's Earth: Grace and Peace
Back in business
Those of you who tried viewing The Earth is Not Flat! in the past week were greeted with an "out of order" message from WordPress. I couldn't get any further, and at one point was informed by the Yahoo Small Business people that I may have lost everything. I have backup files, but because of …
Seas on Titan
The Cassini probe, which is orbiting Saturn, has mapped part of the surface of the planet's largest moon. Like Venus, Titan is covered by a hazy atmosphere, which makes viewing the surface using visible light impossible. The Cassini probe includes a radar mapping tool, which has made it possible to construct a map of part …

Blogosphere theme verse
People blog because they have opinions that they like to share. Here's a thought to keep me humble: I was reading in Proverbs the other day and I think I found the blogosphere theme verse! Proverbs 18:2: "A fool finds no pleasure in understanding but delights in airing his own opinions." That was from a …
One year of “The Earth is Not Flat!”
Happy Birthday to "The Earth is Not Flat!" "The Earth is Not Flat!" had its humble beginning on March 16, 2006. This is the 209th post, and I have had 6170 page views (whatever that means -- is that visits by people, or are many of those visits by automated systems?) I named this blog …
Einsteinstrasse
March 14th is also Albert Einstein's birthday (born in 1879). Here's me on Einsteinstrasse (Einstein Street) in Munich in 2005: Grace and Peace
Pi day (3.14)
March 14th -- a day to celebrate the number pi. I can only recite it to 15 decimal places, which is good enough for most purposes. Q: What do you get if you divide the circumference of a jack-o-lantern by its diameter? A: Pumpkin pi Q: What do you get when you take a cow …
Science textbooks stink (for the most part)
The middle school science textbooks we have been using for many years at BCA are old and worn, so it is time for a textbook search. Being that I cannot go to the National Science Teachers Association convention, I'm looking online for replacement textbooks. One of the first things I found was an article from …

Education Quotes
It is said that another evangelist told John Wesley: "The Lord has told me to tell you that He doesn't need your book learning, your Greek and Hebrew." Wesley is said to have replied: "Thank you sir. Your letter was superfluous, as I already knew the Lord has no need of my 'book learning' as …
