The list [in no particular order]:

Schrodinger, Chadwick, Meitner, Heisenberg, Mendeleev, Fermi, Plucker, Bohr, Maxwell, Seaborg, Oppenheimer, Democritus, Rutherford, Crookes, Millikan, Thomson, Plank, Roentgen, Einstein, Dalton, Aristotle, Geiger, Lavoisier, Kelvin, deBroglie, Franklin (Ben), Dirac, Stoney, Hahn, Curie, Moseley, Faraday, Hahn, and Newton.

Chronological order with their individual contribution. Presentation here is your choice. A powerpoint, colored chart, and/or a colored listing by date are all permissible. The direction and expectation for this portion are purposefully vague.

AND one page on one of them. Double spaced. At least one source.

Extra credit for this assignment: post your opening paragraph on your one scientist here on the blog. If you have trouble posting you can always email me the opening paragraph (the address is on the bottom right of the page).

The assignment is worth 50 points (30 for the chronological list and 20 for the one-page paper). Posting the opening paragraph is worth 10 extra points. The extra credit offer expires at midnight on Christmas Eve.

Merry Christmas everyone.

Our Fate

The link to the picture and the article is here at Science Daily.

Essentially--we're all doomed. 550 light years from here a star is dying. As it dies it grows--gasping for air, as it were. The picture is of that billowing sun.

Our sun will also gasp and billow and expand as it dies.

In another 5 billion years or so.

Great picture, eh?!

Good morning--or afternoon--or evening [pick one that applies, or that you like].

Almost everyone reading my blog (all four of you) lives here in Utah. If you're not living here...really, maybe you should be. Why? Well, let me tell you. Once upon a time I lived in California. Really. I was the consummate California kid. I was the lifeguard, blond hair, and I drove a convertible. Red, of course. I'll save it for another time perhaps, but the lesson was learned, red convertibles are cop magnets. I'm pretty sure it had nothing to do with my driving.


Well, my wife and I moved to Utah in the early 90's. And it was/is completely different. Specifically though, the weather was crazy different. I only recall it snowing twice while I lived in Sacramento. The first time was when I was in second grade, and then again--I think--when I was a freshman. If you wanted snow, in other words, you had to travel to see it. Tahoe, or the like was the best option. The whole family would pile into the station wagon (really) [it was really large and green--a Chrysler with wood paneling, and a huge 440 c.i. under the hood] (you'll have to remind me later to tell you about taking a ride with the pets in it--funny stuff). That's not the case here. The snow I mean. Well, the station wagon too. It's been snowing a bit here in Utah lately. From the last storm the mountains here got several feet of fresh snow. The valleys got plenty and we had to shovel our way out.

It's not a bad gig though--the snow I mean. There is something wonderful about the quietness and serenity of the snow. Yes, I love the whiteness of it too. The way it blankets our ground is truly beautiful, but it's the weatherness of it that I love. Clouds, water, temperature, falling snow, and that sound it makes as you step into that fresh blanket of snow. Small flakes, large ones too (I had always heard that eskimos had like 20 words for snow--each one for a different type; I heard too that was a myth) all make me smile. There, is just something great about the snow and the weather it brings with it. I don't ski or snowboard--my kids do though.

But, this California kid loves the seasons and the Greatest Snow On Earth.

So...let it snow, let it snow, let it snow.

Stoichiometry Quiz

This is the quiz question.... Your welcome.

A 34.5 gram piece of metallic iron is dissolved in concentrated HCl--the two react.
The reaction formed H2 and FeCl2
Fe + HCl > FeCl2 + H

How many grams of the product iron (II) chloride are formed?

So, to do this problem you will need to:
  1. balance the chemical equation. 
  2. convert what you know (the mass of the iron) to moles (look on the periodic table)
  3. convert to the moles of what you want
  4. convert to mass of what you want (again, a periodic table thing)

well that's all the help i'm going to give you... nRaine...  make sure you now how to do stoichiometry... it will save your butt so many times in the future.     see ya later.

A couple of Biology assignments

Tuesday, December 1, 2009


So, to make a long story shorter (and saner), I was helping Nathan with his AP Chem...and I was looking at the geometry for tetrahedrons. A very long and complicated page (here) discussed the derivation of angles and the like with the following paragraph (it does, incidentally, give a remarkable similar tone to the entire page--a flavor, if you will):

Note to teachers: if you build an octahedron and a rhombic dodecahedron off the octahedron faces (use the Zometool), and then attach a tetrahedron off one of the octahedron faces, the centroid of that tetrahedron will be the vertex of the rhombic dodecahedron. In fact, the distance from the centroid of the tetrahedron to each of it’s vertices is the edge length of the rhombic dodecahedron! Nature is not only beautiful, but also logical and consistent.

 I got lost after "Note to teachers." 

It was a long night. 

Nathan wanted me to be sure to note that the author of this page and the subsequent paragraph derived the root angle of a tetrahedron (109.45) for those interested--FROM SCRATCH! 

I officially feel dumber. 

Genetic Disorders

Hello Biology students.

Your assignment (whether you want to or not) is a one page paper about a genetic disorder of your choosing. 12 point font, Times New Roman or similar. One inch margins.

To get started you show go here: The Genetics Disorder Library, from the University of Utah (kudos for a killer site). Really, it's a great website that has enough information to do your one page paper.

You'll need to cite your source...and if you get it from the link above the source is linked in the bottom right corner of the page. 

For 5 extra credit points applied to this assignment...two or three sentences posted to this blog about your disorder (well, not your personal disorder--just the one you're writing about will suffice).

Get it?

Got it?
