Now that I think about it...Lake Michigan DOES look some what like Florida...

Oh and AlphaTauri ( I like your name ^.^), our coach gave us a sample national test and we did better on that than our regionals astronomy test. On our regional's astronomy test we had questions like "What was the initial mass fraction of hydrogen in Population III stars?". I've been searc...

I feel like Sounds of Music and Forestry are the hardest events because of all you have to know/do for the competition.

Good. At least it's normal that I feel overloaded with all the memorization of forestry. States in two days. SO nervous.

So anyone want to help me distinguishing between the pines? ^.^

Thank you! And is the Mockernut Hickory on the national tree list or no?

In the Audubon book, it says glabra usually has 5 leaflets. Also, I don't know if this is specifically to Michigan but also how do you tell the difference between Carya Tomentosa?

Hmmm which event do you think is the hardest?

I understand that Carya Cordiformis has nine leaflets, but one of the people above said that Carya Glabra has the nuts but Carya Ovata also has nuts so how would you tell the difference between Carya Ovata and Carya Glabra? Is there any way to tell just by the leaves?

I think yellow birch has the yellow flowers while sweet birch has longer/slimmer reddish/orangish flowers...Don't quote me on it though...

Hmmm I have a question. Say you know a galaxy has a hydrogen line at 656 nm. The redshifted line is now at 1115 nm. What would be the redshift value and how fast would the galaxy be going. Also, how far is the galaxy away from us? (H= 70) Check my work please :) So you can find redshift by using (o...
