The Tourist

For my Geology lab assignment, I have to look on my university campus for a fossil of any age and take a picture.

I noticed that some places in the concrete sidewalk have impressions of leaves. So I guess this could be considered a trace fossil, right?

How are geologists able to reconstruct ancient continental positions, and at what latitude they were? Does it have to do with rocks and magnetism?

~(KvP)v~H, P |- ~H

The premises are: ~(KvP)v~H, P

The conclusion is: ~H

I'm trying to learn the wedge elimination method of using proofs and this is one of the practice problems.

I can't get past this:

1 (1) ~(KvP) v ~H A

2 (2) P A

Thanks to anyone that has any idea what I'm talking about!

Our lab group had to measure the lethal effects of UV light on bacteria. We used nutrient agar plates with bacteria on them, and put them in a UV exposure box. One plate of Bacillus megaterium was exposed for 15 minutes, and another for 30 minutes. One plate of Staphylococcus epidermis was exposed for 2.5 minutes, the other for 5 minutes. B. megaterium is endospore-forming so we knew it would take longer to kill the bacteria. Half of each plate was covered with an index card when exposed (so one side could be the control). After exposure the plates were incubated for 31 hours. The problem is that there was no difference between the control and exposure sides. All of the plates showed growth, the UV light seeming to have no effect. Other lab groups had pretty much the same results (some groups exposing B. meg for up to 1 hour, staph for 10 minutes). What went wrong? Too little exposure? Faulty UV box? Human error?

In reading the letters to the editor in a newspaper, I found a letter from a man in my hometown (hmmm). In it, he said:

In ___'s letter, he seems to be saying that anyone who does not accept the theory of evolution does not have a truthful outlook on science. Many of the major "finds" supposedly supporting evolution were mistakes or hoaxes. The very bedrock of this theory is unscientific. It gives animal life more intelligence than man and actually gives them supernatural abilities. The theory of evolution says that animals looked into the future, saw that there would be changes in their environment, and changed accordingly (taking thousands or millions of years to do so). This is science? One evolutionist said, "Evolution is unproved and improvable, but the only alternative is Divine creation, and that is unthinkable." Why don't the evolutionists prove evolution? The evolutionists themselves are the proof of the Divine inspiration of the Bible. Read 2 Peter Chapter 3, verses 2-8."

Any information on them? Will they be out in 2007?

Sans the assassination of Franz Ferdinand. I'd like to know what some of the events that led up to this were. Why did Russia, France, Great Britain, Germany, etc get involved when a Serbian killed an Austrian?

If so, how and why?

Which of these is correct? the Hebrew wording is: "Yam Suph"?

From the publication of "On the Origin of Species" in 1859 until the Scopes Trial in 1925. I would like to know what scientists and others thought about evolution after Darwin's publication. How long did it take until scientists other than Wallace accepted it?
