o       I am a math professor at Southern Utah University, recently ranked one of the Top 10 Universities in the Nation for quality and value by Consumer's Digest. Right after my Ph.D. we went to Arkansas State University in Jonesboro, Arkansas for five years.  My doctoral degree is in partial differential equations (PDEs), received under Renate Schaaf at Utah State University (1996).  I also had an emphasis in numerical analysis.  You can see some more work information here.

o       Besides working to advance my research in PDEs, I have done doing research with Bruce Johnson in the physics department at ASU and Rick Puetter at UC San Diego (at the center for Astrophysics and Space Sciences).  This project involves detecting the underlying energy layers in ion channels using a statistical maximum likelihood method called the Pixon method.  Most fits in the past have been done with a few discrete exponentials, but we find it plausible to consider a continuous distribution for the energy layers.

o       Math has got to be the best subject to teach.  I think it is so great because it is not nearly as much memorization as it is developing abilities, logical processes and techniques to apply to problems to be solved.  All sciences are fun in the same way, but then I don’t have to spend tons of time putting together labs!

 


 

 

  • I do a lot of work on Mathematica, including courses, advanced programming, research-related activities, and online key solutions to computer-based problems for Williamson's differential equations textbook.  I was also an alpha and beta tester for the Calculus Wiz package for Mathematica.
  • I program in Fortran and passable C++ (I'm no object-oriented programmer--a big omission, I grant you!).  Most of my programming has been in numerical analysis of DEs and PDEs.
  • I use IDL software as well since the Pixon code we're using is programmed in that language.

 


 

 

o       I am married to the former Tifani Acord of Bountiful, Utah.  (She was gracious enough to change her name to Armstrong when she married me!)  She is my best friend, and the most wonderful and beautiful person I know.  We now have five children: Lindsay (17), Cameron (15), Ryan (13), Katelyn (9), and our bonus child Luke (5).  Being a parent is the greatest and most important thing I can imagine.  I can’t believe I am “old” enough to have five kids—especially a teenager!

o       Here are some pictures of the family

o       My favorite thing to do in my spare time is just to spend time with my wife and children.

o       My family and I are members of the Church of Jesus Christ of Latter-Day Saints.  I was Bishop of the Jonesboro Ward for nearly four years during our five-year stint in Arkansas.  I have a passion for good religious literature, whether it be from our church or about religion in general, including pseudepigraphal works, Gospels both canonical and apocryphal, and the Dead Sea Scrolls.  I believe that Christianity is a dynamic belief: That is, it’s not a set of rules that we are to follow, but a way to change our lives by changing the spirit inside to move toward the perfection Jesus told us to seek.

o       I like to jog, play basketball, and lift weights.  I also love to play catch with anything: baseball, football, or Frisbee (sorry, novelty flying disc).  Luckily, all of my kids so far love sports, so I never have to throw things up in the air to myself.  I have coached my kids’ soccer, baseball, and basketball teams lots of times.

o       I enjoy being in the outdoors, to fish, camp, or just enjoy nature.  There is no better place to do this that I have ever seen than in southern Utah—mountains and canyons and streams, oh my!

o       I love reading, and when I don't have time to open up a book listening to a book on tape suits me fine.  I am a fanatic of religious literature, especially of the ancient Christian genre (my favorite: The Shepherd of Hermas) and classics.  All the best stuff is there: The greatest minds from the past.  When one can read ancient religious literature or Dostoevsky, Joyce, Hardy, Conrad, Forster, Tolstoy, Twain, Melville, Maugham (one of the best!), Buck, Wells, Stoker, Steinbeck, Shelley, or even Stephen King (now there’s a decent modern writer), it is hard to be patient with the others, or especially with television.  I wish I could find a show that I thought was worth watching, though, besides The Simpsons reruns and sports….

o       Some of my favorite links follow:

*      http://www.wordsmith.org/anagram/  You can find anagrams for anything--try the advanced option and restrict it to at most two words!

*      http://www.phonespell.org/  Like the one above? Here’s a similar one. You tell it your phone number and it gives you back all possible phrases it spells as a mnemonic device.

*      www.gregpalast.com Greg Palast is absolutely the best journalist at exposing corporate influence in political decisions and vice-versa, along with many other interesting sidelights. 

*      http://skyandtelescope.com/observing/almanac/  The most amazing site on the Internet!  It has comprehensive star maps for any location and any time of night.  Tifani thinks I should have gone into astronomy instead of math since to her I seem more impressed with the former.  I guess I have to admit that astronomy can be as stimulating as even the best mathematical proof; however, it would drive me crazy to never be able to visit the places I study.

*      http://bible.gospelcom.net/  Has all versions of the Bible (except the NIV Study Bible—the best one of all in my opinion).

*      http://www.juancole.com and http://www.antiwar.com  From the beginning of trying to link Hussein and bin Laden, along with the lies about the “yellowcake tubes” in Niger, all the way to currently saying that (Shiite) Iran is providing weapons to al Qaeda (a Sunni terrorist group!), I’ve been more frustrated than I can possibly say with (a) our neoconservative leaders, and (b) the American public that will not study enough of what is going on to oppose this nauseating screed.  I told many people as leaders were beating the drums of war that it would be a terrible disaster.  They wanted to attack a country (Iraq) proven to be no more a threat to anyone. Why is violence the only answer politicians can come up with?  What is wrong with actually sitting down together and talking about differences?  Some of my favorite quotes about war - and violence in general – follow.  

 

I hate war as only a soldier who has lived it can, only as one who has seen its brutality, its futility, its stupidity. –Dwight Eisenhower

 

All murderers are punished unless they kill in large numbers and to the sound of trumpets. –Voltaire

 

War is a way of shattering to pieces, or pouring into the stratosphere, or sinking in the depths of the sea, materials which might otherwise be used to make the masses too comfortable, and hence, in the long run, too intelligent.  –George Orwell, 1984

 

It is a universal truth that the loss of liberty at home is to be charged to the provisions against danger, real or pretended, from abroad.  –James Madison

 

But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also. –Jesus Christ, Matthew 5:39
