     -   Applications of exponential functions:  musical scales, equal tempered vs. just toned scales

          Have you ever wondered how the frequencies for musical notes are determined?  It turns out that an exponential function, specifically 2n/12, is heavily involved in the modern 12-note chromatic equal tempered scale, successor to the old just-tone scale used before the time of J.S. Bach.  Here’s a link to a discussion of the equal tempered musical scale and practical piano tuning, as well as Prof. Oates’s Excel spreadsheet investigating some of the formulas presented in the above discussion.  If you’d like *much* more information on the physics of music, see this Michigan Tech web page.

     -   Solution Guide for Module 4 Dosage Range and “Is it safe?” Problems

              Some problems in the text and in Worksheet 32 are dosage range or “Is it safe?” problems.  Click this link to receive more information on dosage range/is-it-safe problems. 

These problems require that two sets of calculations be made, one for the LOW LIMIT of the dosage range and one for the HIGH LIMIT.  The ordered dose is then compared to these limits to see if it is either within limits and, therefore, SAFE or outside the limits and, therefore, potentially UNSAFE.  Note that both the limits and the ordered amount must be in the same units.

     -   More Module 4 Problem Solutions

              Here are some solved problems drawn from e-mail messages sent to APPM 1313 students recently.  These should assist you in working the Module 4 homework.

.    -   Erratum, Module 4 Problem from the Textbook

              The text’s incorrect answer to problem 3, page 216 is 9.7 mL/dose.  The correct answer is 4.8 mL/dose. 

              The previous edition of the text had this same question, but in that edition the medication label displayed a concentration of 125 mg/5 mL; since the new label’s concentration is 250 mg/5 mL, the required number of mL is half that stated in the answer section.

    Module 5

     -   Practice Test 5 is available here.

              On the real Test 5, questions 12 – 16 will be replaced by dilution problems similar to those on Worksheets 40 and 41.

     -   Help for Module 5 Dilution Problems

              When synthesizing (building) dilution setups, you’ll need this write-up on Chuck's Quick and Dirty Dilution Technique, CQDDT.

              Here’s a copy of an e-mail response I sent to a student requesting help on Module 5 dilution problems.  You should read and try to understand the material in Worksheets 36 through 39 before reading this document.

     -   Help for Linear Equations, y = mx + b

              Material describing properties of linear equations is available here.         

     -   Worksheets for Module 5 are available using the links that follow.

              Module 5 Worksheets:  WS 34, WS 35, WS 36, WS 37, WS 38, WS 39, WS 40, WS 41, WS 47, and WS 48.

              Landscape-oriented Versions of Worksheets:  WS 38L and WS 39L

    -   Grades for previous semesters are available on the OCCC MineOnline system.  Here’s a procedure for viewing them.

 

o  Guide to Academic Costume and Music

     -   Since graduation is just around the corner, it’s time to develop some skill at “reading” the academic robes and to get some background on the academic song “Gaudeamus Igitur.”  Here’s an academic costume and music annotated webography to get you started.

MCj03052850000[1]

o   Prof. Oates’s Earlier Pics
         
These pictures have been moved to
the CLOates Family Website.

o  Blog Moved  

     Prof. Oates’s blog, formerly located at chuxstuff.blogspot.com, can now be found at ProfOates.blogspot.com.   

o  Math Help (Other Subjects, Too!) 

    Lots of help for math and other subjects is available at KhanAcademy.org and free-ed.net.  Give them a try.

o  View the Near-beta Version of Prof. Oates’s Math Info Site  

     You can view and comment on Prof. Oates's (New) Math Information Site, still under construction.  Your constructive comments and problem reports will be much appreciated. 

     If you need to construct a website in a hurry, consider wordpress.com for the task.  I reconstructed the website you are reading on the WordPress’s blog site in about 12 hours total (so far). 

o  Scale of the Universe

    Here’s a literally mind expanding website where you’d do well to spend some time.

o  Top Ten Lists for ChuckOates.com   (updated 2010-01-29, reformatted 2010-02-12) 

     Top Ten Lists of most frequently accessed pages, images, and blog entries on this website are now available. 

o  How NOT to Analyze Data

     "Global Warming Stopped in 1998"  Oh, really?  Here's a classic case of 1) playing fast and loose with data, cherry picking a short segment while ignoring the bigger picture and 2) complete failure to understand the complexity of the system that's being discussed.  At best, it's a manifestation of ignorance; at worst, it's a classic propaganda technique.  Have a look at the big picture here .  Be careful not to make such an error yourself or unwittingly spread the results of someone else’s erroneous analysis.  A statistics course [find “Statistics”] is a useful prevention for some of these kinds of errors.  So is the study of propaganda techniques.

o   National Weather Center Open House

Here are a number of pictures made at the NWC Open House, 4 November 2006, Norman, Oklahoma, USA.

o   Severe Weather Footage, 5:30 p.m. – 5:45 p.m., 10 May 2010

Here are some thoughts on careers for those considering their futures and, particularly, for those graduating at various academic levels this spring:  Lookin' for a Career? 

o   Images from the News

Recent oil drilling platform explosion images,  Maps of the Gulf of Mexico oil spill,  Iceland's Eyjafjallajokull volcano

o  How to Tawk Texan  MP900362846[1]

     Texas:  it’s like a whole different ... planet.  Here’s your guide to Texas Ang-lish, so you can sound like a native when you visit.  For those who wish to take the advanced course, The Unofficial Texas Dictionary is also recommended, but it’s definitely second-semester stuff.  You can find some colorful Texas expressions at this address, also.  You’ll find a Texas travel guide here.  Don’t forget Texas’s most under-rated attraction, the Palo Duro Canyon, presented here in pictures and as a virtual tour.
