Learning Classical Guitar, the Saga continues!

Ahh ... the pursuits of Summer! Finally, it's time for some R&R. I know, perish the thought, but its time for some non Math related activities! In fact, I'm off for the whole Summer for the first time in 30 years! Can you believe it? I'm still pinching myself. I guess this is a practice run at retirement? Now I finally have plenty of time to devote to walking, biking, swimming and eating right! For me, the Summer is a spiritual time to regroup and fortify myself mind, body and soul for next school year. I like to focus on outdoor activities for exercise and a good diet. Its also time for more soulful activities of Wood and Stone such as playing chess and classical guitar. I'm attending to some of my old hobbies such as gaming, reading and catching up on genre TV and film.

I haven't blogged much about this but, not only am I a Science Fact slash Science Fiction geek, but I am also a huge Classical Music geek! I am into all periods of instrumental music from chamber pieces to orchestral. I'm especially enamored of all forms of "Classical Guitar." I played the violin from 7th to 12th grade in school some 33 years ago. I was 1st violin for all 4 years of High School. I was even the Concert Master and Conductor from time to time. So, a few years ago, I thought I could teach myself how to play Classical Guitar! I love all periods of guitar repertoire: Baroque, Classical, Renaissance and Modern. I've played Violin, Mandolin, Guitar and Lute. I love Baroque, Spanish, Flamenco and Celtic tunes too! So, in my "copious" free time, I've not progressed very far, but it's been a fun journey. What follows, therefore, is a Math slash Physics Teacher's take on alternative tunings for the Modern Acoustic Guitar with nylon strings. I suppose I'll have to take off my Computer Science hat since we haven't dealt with microprocessor clock speeds in Hz since Grace Murray Hopper and the Harvard Mark I!

First, I tried classic finger style guitar a la Andres Segovia and Fred Noad. The problem with Modern Standard Guitar Tuning is that it mixes 4ths and 3rds? Since I'm used to the Violin which is tuned to all perfect 5ths, the fingerings and deciphering standard notation on the Guitar turned into a massive headache for me. So, I ended up using a lot of TAB. You know, if I were a High School student today, for all that everyone thinks I'm a math and computing genius, I would be classified special ed! I have a very bad memory and I'm dyslexic. So, I really have a hard time learning new things. That's why I'm a Math teacher, I derive everything I need from scratch each day depending on the topic at hand. That way I don't have to memorize much. Now, I even need reading glasses to see anything small or close up. I blame TI for that. I've been peering at Graphing Calculator screens everyday for the last 20 years. If they were like today's iPod screens which are back-lit, hi res and hi color, that would be one thing. However, the TI screens are all dark, low res and grey scaled ... ugh!

Standard Guitar Tuning
High (reference)
string 1: E4 329.6 Hz
string 2: B3 246.9 Hz (3rd)
string 3: G3 196.0 Hz
string 4: D3 329.6 Hz
string 5: A2 110.0 Hz
string 6: E2 82.41 Hz
Low

This is the standard tuning for the modern acoustic guitar. All the strings are tuned a perfect 4th apart with one exception. The interval between strings 3 and 4 is only a 3rd. Its very confusing to play with such a tuning when you're used to all 5ths tuning on the violin!



Then I tried the flamenco style when I got myself an Esteban Guitar. The price (I got it off QVC) was not bad for a decent guitar, case and amp! The problem with the Esteban technique is that it was not based on standard music notation, nor was it based on Spanish, aka modern, guitar TAB. It was based on playing by ear or by watching the fingerings on his VHS tapes or some wacko notation he made up!

Alternate Flamenco Guitar Tuning
High (reference)
string 1: E4 329.6 Hz
string 2: B3 246.9 Hz (3rd)
string 3: G3 196.0 Hz
string 4: D3 329.6 Hz
string 5: A2 110.0 Hz (5th)
string 6: D2 73.42 Hz
Low

There are a lot of variations when tuning the Flamenco Guitar. This one is called the "DAD" variant. Its simple to retune a standard guitar by dropping the 6th string one step from E2 to D2 giving a 5th interval between strings 6 and 5.
I finally broke down and went back to my violin roots learning Mandolin Scores. Playing the Mandolin is a lot like playing the Violin except you use a pick. Also, tuning the Mandolin is a lot like tuning the Violin with perfect 5ths except its like a Lute in that it has courses not just single strings. Courses are 2 strings tuned to the same pitch. So, the Mandolin still has 4 pitches like the Violin, but it has 8 strings! Playing the Mandolin was fun and brought back memories of my Violin repertoire. However, the timbre of the higher courses were too tinny for my liking.

Standard Mandolin/ViolinTuning
High (reference)
course/string 1: E5 659.3 Hz
course/string 2: A4 440.0 Hz
course/string 3: D4 293.7 Hz
course/string 4: G3 196.0 Hz
Low

This is the tuning I'm used to as it uses all 5ths as intervals between each pair of strings. BTW, retuning a guitar is easy if you have an electronic tuner. I have a cool app on my DROIDX smart phone called gStrings. It samples inputted audio and tells you what frequency and note you have tuned a particular string to ... very handy!


Standard Viola Tuning
High (reference)
string 1: A4 440.0 Hz
string 2: D4 293.7 Hz
string 3: G3 196.0 Hz
string 4: C3 130.8 Hz
Low

Note that this tuning is just like Violin tuning except the 4th string starts a 5th below.


Standard Cello Tuning
High (reference)
string 1: A3 220.0 Hz
string 2: D3 146.8 Hz
string 3: G2 98.00 Hz
string 4: C2 65.41 Hz
Low

This tuning is like the Viola except that every string on the Cello is tuned an octave below the corresponding string of the Viola (note all frequencies are half as much, eg A 440 becomes A 220).


Standard Bass Tuning
High (reference)
string 1: D3 146.8 Hz
string 2: G2 98.00 Hz
string 3: C2 65.41 Hz
string 4: F1 46.25 Hz
Low

Bass tuning is to the Cello as Viola tuning is to the Violin since all strings are a 5th lower!
Finally, I discovered a great music teacher, Allan Alexander and all his scores and CDs on EBay! I consider myself lucky to have had 2 great music teachers in my life. Pedro Biava was my first teacher. He taught me the Violin and conducted the High School orchestra. He was also director of the Longwood School District's Music Program. He started it on a prayer and grew the program to great success over his 30 year career. He also played a mean Cello. My second teacher is Allan Alexander. I discovered his website (see link above) and his EBay store. That's where I purchased all his score books and CD bundles for learning to play the Guitar and Mandolin. His master piece, however, in my opinion is "The Guitarist's Lute Book." This ingenious book was all about playing French TAB for the 6-course Renaissance Lute on the modern Acoustic Guitar simply by down tuning the G string to F# and placing a capo on the 3rd fret thus achieving Standard Lute Tuning on the guitar. Also, learning French TAB was easy, with Allan's help! It's like Spanish TAB, except instead of numbering the fingerings as 0,1,2,3,4,5 letters a,b,c,d,e are used. Also, the letters are in a fancy font: c looks like r so as not to confuse it with e and d looks like a lowercase Greek letter delta. BTW, I can be forgiven for playing TAB here as most, if not all, surviving Renaissance Lute music was recorded in French TAB (sample below).

Standard LuteTuning
High (reference)
course 1: G4 392.0 Hz
course 2: D4 293.7 Hz
course 3: A3 220.0 Hz (3rd)
course 4: F3 174.6 Hz
course 5: C3 130.8 Hz
course 6: G2 98.00 Hz
Low

The first thing I learned from Allan was how to tune a Guitar as a Lute. Simply take a standard Guitar, tune the 3rd string down a half tone from G to F#. Then place a capo on the 3rd fret!

Now, I finally decided to try my own tuning! I wanted to go back to 5ths tuning on the Guitar so I could easily play it as a Mandolin. I'll call mine Cello Guitar Tuning which is somewhere between the New Standard Tuning (NST) and MandoGuitar Tuning. The California Guitar Trio in the YouTube above is known for using NST. With my tuning I can play finger style guitar with mandolin, violin and even Cello Scores!


All 5ths Guitar Tuning
High (reference)
string 1: B4 493.9 Hz (too high)
string 2: E4 329.6 Hz
string 3: A3 220.0 Hz
string 4: D3 146.8 Hz
string 5: G2 98.00 Hz
string 6: C2 65.41 Hz
Low

This would be the ideal tuning as the intervals between each pair of strings is a perfect 5th. However, the standard high E string on the guitar will snap when tuned to 493.9 Hz! The solution here would be to get a string with a slightly smaller wire gauge and replace the E string with it. I'll have to experiment with other gauges.


New Standard Guitar Tuning
High (reference)
string 1: G4 392.0 Hz (3rd)
string 2: E4 329.6 Hz
string 3: A3 220.0 Hz
string 4: D3 146.8 Hz
string 5: G2 98.00 Hz
string 6: C2 65.41 Hz
Low

NST was put forward to solve the problem of streching the high E string too much. The compromise here is to give up the perfect 5th interval for just the highest pair of strings and tune to a perfect 3rd instead. They say this makes for easier chords but I'd like to stick to all 5ths somehow.


MandoGuitar Tuning
High (reference)
string 1: E4 329.6 Hz
string 2: A3 220.0 Hz
string 3: D3 146.8 Hz
string 4: G2 98.00 Hz
string 5: C2 65.41 Hz
string 6: F1 43.65 Hz (too low)
Low

MandoGuitar takes the tradition of the Classical Guitar player's playing treble clef violin or mandolin scores as is, without transcription, tuning the guitar an octave lower. The standard high E 329.6 (an octave lower than the high E on the Violin) is retained but the rest of the guitar is tuned in 5ths. You could probably play Cello repertoire as this tuning will include Cello tuning A3, D3, G2 and C2! However, F1 is too low a frequency even for the highest gauge string.


myCelloGuitar1 Tuning
High (reference)
string 1: E4 329.6 Hz
string 2: A3 220.0 Hz
string 3: D3 146.8 Hz
string 4: G2 98.00 Hz
string 5: G2 98.00 Hz
string 6: C2 65.41 Hz
Low

Here's my solution for fixing the MandoGuitar F1 problem! However, G2 on string 4 is still a bit too loose.


myCelloGuitar2 Tuning
High (reference)
string 1: E4 329.6 Hz
string 2: A3 220.0 Hz
string 3: D3 146.8 Hz
string 4: G2 98.00 Hz
string 5: C2 65.41 Hz
Low

Here's my final solution for the MandoGuitar F1 problem - just 5 strings! G2 and C2 on strings 4 and 5 are a bit easier to play. So, get rid of the standard D string and restring! In other words, move the 2 lowest strings from positions 5 and 6 up to positions 4 and 5 then retune to G2 and C2. 5 strings is enough for what I want to achieve: a Guitar on which you can play Violin and Cello scores easily. Maybe a higher gauge string 6 would work, but the guitar would have to be redrilled too.


Bach, johann sebastian prelude from suite no.1 for unaccompanied cello sheet music - 8notes from A Jorge Garcia


So, in conclusion, my favorite tuning is Allan's 6-course Renaissance Lute! However, I will try some Violin and Mandolin repertoire on my CelloGuitar. I'm using CelloGuitar1 right now, but I will be trying CelloGuitar2 or all 5ths with a thinner string1. I always wondered how the Classical Guitarists play Bach's Cello Suites on a standard guitar since the transcriptions would have been horrendous! Now I know, they just retuned to 5ths!


Well, that's all folks. I hope you enjoyed my latest blog on Summer diversions. I know it's unusual for this blog to touch on genre related topics and hobbies and such. You can expect, however, a few more along this vein this Summer!

Great Science Fiction & Fantasy: What not to watch ... on TV?

Ahh ... the pursuits of Summer! Finally, it's time for some R&R. I know, perish the thought, but its time for some non Math related activities! In fact, I'm off for the whole Summer for the first time in 30 years! Can you believe it? I'm still pinching myself. I guess this is a practice run at retirement? Now I finally have plenty of time to devote to walking, biking, swimming and eating right! For me, the Summer is a spiritual time to regroup and fortify myself mind, body and soul for next school year. I like to focus on outdoor activities for exercise and a good diet. Its also time for more soulful activities of Wood and Stone such as playing chess and classical guitar. I'm attending to some of my old hobbies such as gaming, reading and catching up on genre TV and film.

This posting was supposed to be about great SciFi TV that you can't watch on TV much anymore, but you can see, mostly FREE, on Amazon Prime and on your Kindle Fire. I'll get back to that, but first, here's an update on more current SciFi you can watch on TV! BTW, I've had Amazon Prime for years to get free 2-day shipping on all my books. Recently, this service was upgraded to include tons of TV episodes and movies, many for FREE. It's like getting NetFlix for FREE! Well, not FREE actually, as I was already paying $69 per year for Amazon Prime. I will also note if each series is available on Amazon Prime and Kindle Fire and provide links to sample episodes. BTW, Amazon Prime is built into your Kindle!

What follows is a list of my top 10 genre TV shows, past and present. The first 4 are the current shows and the last 6 are off the air listed in chronological order of appearance on TV. I'm not playing favorites here, but I am partial to Merlin of late!

(1)    OK, I admit it, this is my guilty pleasure. I got hooked on Supernatural when I was home sick with the flu a few years ago and caught a pile of reruns on TNT. I know, I know, this isn't Science Fiction nor is it Fantasy, its more like Horror, but the whole stopping Armageddon story arc was fascinating! This past season was post apocalyptic and not all that exciting until Arch Angel Castiel (youtube link) came back. It was interesting how they got Bobby, Sam and Dean's pseudo father figure and mentor demon hunter, back into the fight as a ghost for a while and touching when they finally let him go.

(2)    Now, this series is a lot of fun for the Fantasy genre, unless you think Camelot was real! Merlin chronicles the adventures of the young wizard. That's right, we meet Merlin before he's come into his full power. In fact, he's Prince Arthur's man servant??? I think it took 4 seasons (youtube link) before Arthur becomes King and takes Excalibur from the stone! There's even a great dragon character with the perfect voice of John Hurt. I caught the first season by accident a few Summers ago as a filler on NBC. Then, this series was snatched up by SyFy and each season is better than the last. I think it originated on the BBC.

(3)    Wow, what a shame this one was cancelled. So, I guess I lied, you can't watch this one on the air after all! The first season is on Kindle, so enjoy. TerraNova (youtube link) is about a family from 2149 that goes back 70 million years to start a colony in the midst of dinosaurs and all kinds of weird threats. Good thing too, the future is overpopulated with few remaining resources - you can't even breath the air without a rebreather! TerraNova was on during the Fall of 2010 for a half season on Fox. I thought it was coming back in the Spring for another half season, but it never did. Gotta love those half seasons! It was cancelled before the Fall of 2011. I hope SyFy picks this one up as it had a very promising beginning. Fox finally got a genre series on that I liked! Sorry, I never really got into the X-Files, Heroes or Fringe....

(4)    Falling Skies (youtube link) is great! It's about a present day family thrust into combat with invading aliens and the aliens are winning! The alien invaders have destroyed every major city and taken many humans as slaves. There's but a few resistance forces left. Noah Wyle plays the father, Professor Mason, of three boys. This history professor soon becomes a leader in the 2nd Mass. This resistance cell is in Massachusetts and is fighting the aliens in the spirit of our own revolutionary war against the Red Coats (hence, the history professor connection)! The first season was produced by Spielberg and the current season is being produced by Noah Wyle of ER and The Librarian fame. After each show, http://www.fallingskies.com has an interview with cast and crew conducted by Wil Wheaton. Don't miss this series currently on TNT!

Now, back to what not to watch on TV. I've been watching great SF&F TV and Movies since the 1960s as recommended below and reading great SF&F novels since the 1970s. I remember the days before VCRs and DVRs when you had to watch every single first run episode live! I think I've watched every single first run episode of all the Star Trek series live since the very first season in 1966 even when VCRs became all the rage. In fact, I still have every single Star Trek: The Next Generation on VHS that I taped live starting with my first VCR in 1987! BTW, I am using SF&F here to stand for Science Fiction & Fantasy as opposed to Science Fact & Fiction as in the case of I-CON and my EBay store: SFFBCLUB, the Science Fact and Fiction Book CLUB.

What follows is a list of my favorite SciFi TV shows that I've been watching loyally over the years. I think that I've seen most as first run episodes with the exception of the first Twilight Zone series and the first Outer Limits series. I recommend all these shows, however, I highly recommend those with an (*) mark. For instance, the original Twilight Zone was far superior to the remakes. However, the 1995 version of Outer Limits on ShowTime was a vast improvement over the original! Also, I note whether or not each series is available on Kindle Fire and whether its FREE on Amazon Prime. For the starred seasons, I also linked my fave ep! BTW, please note that the Kindle Fire is not just a great ebook reader, its a fabulous 7" Droid Tablet with WiFi!

1) Twilight Zone, 1985
1) Twilight Zone, 2002
     I grew up with the Space Race and Star Trek: The Original Series. In conjunction with that, I was introduced to the wonderful world of reruns watching I Love Lucy, Twilight Zone and Outer Limits. When anyone brings up the best Twilight Zone (youtube link) episode, they always go with the Shatner episode with the gremlin on the wing at 20000 feet or "The Eye of the Beholder." However, my favorite episode, by far, is "Time enough, at last" with the legendary Burgess Meredith (linked above). This episode is about a poor old bookworm who can't seem to find enough time to read. Of course, there's a classic twist at the end, but I won't ruin it for you if you haven't seen it yet. T-Zone has always been one of the best written shows on TV. This show follows in a long tradition of live plays on early TV and SciFi short short fiction. Don't forget that Rod Serling also wrote the first Planet of the Apes movie in the same twisty style!

2) Outer Limits, 1963, $1.99 per episode on Kindle Fire
     The New Outer Limits link I selected is actually a remake of an original series episode. "I, Robot" (youtube link) stars Leonard Nimoy and is loosely based on the Asimov stories about robots. What's interesting here is that Nimoy starred in both episodes. In the original version, I think he played a minor role as a newspaper reporter. In the remake, directed by Adam Nimoy no less, Leonard plays the defense attorney in a case where the Robot is accused of murdering his creator!

3) Star Trek: Voyager, 1995, ALL Seasons FREE on Kindle Fire
3) Star Trek: Enterprise, 2001, ALL Seasons FREE on Kindle Fire
     Star Trek is, IMHO, the best of the lot. The acting was good, the Shakespearean themes were current and the music was based on impressionist classical scores! I remember growing up on such fare in the 1960s. Then, of course, there was nothing but reruns in the 1970s until the Star Wars franchise changed all that in 1978! The rest is, as they say, history as Star Wars took off in theaters and Star Trek: The Next Generation took off in the 1980s back on TV. So, these linked episodes are indeed my all time favorites. For ST:TOS, I chose the episode that introduced the Romulans for the first time and the great Mark Leonard (who, for some strange reason, I confuse with Martin Landau from Space 1999). Leonard (youtube link) played the Romulan commander of an invading force with a top secret weapon. This weapon was a powerful plasma cannon coupled with the first cloaking device. This episode was a great game of cat and mouse with Kirk giving chase in the classic style of a WWII silent running submarine movie.  Leonard, of course, went on to play Spock's father in later episodes of both TOS and TNG as well as the movies. ST:TNG's link is "The Inner Light." I think this one won an Emmy for Patrick Stewart. In this episode Picard is swept up in a dream life on another world. He actually experiences an entire life on that planet and learns all about the other 1000 year old culture now defunct. This is one of the most impressive episodes of TNG. Dr. Crusher chalks it up to an ordinary dream but Picard even remembers how to play a recorder after he returns to his normal self - something he never knew how to play before. That flute comes out in subsequent episodes too! How amazing it must be to experience an entire lifetime in just 15 minutes of real time be it a dream or not! There's lots of great DS9 episodes, but I had to pick "Trials and Tribbulations." Gotta love those Tribbles! This ep is marvelous as it includes Sisco and Dax traveling back in time and joining the crew of Kirk's first Enterprise during the the original "The Trouble with Tribbles" story!

4) BattleStar Galactica, 1978, $1.99 per episode on Kindle Fire
4) Caprica: 2009, $1.99 per episode some FREE previews on Kindle Fire
     The original BattleStar Galactica was a bit campy, but the newer version was great! Too bad its over! Edward James Olmos (youtube link) was awesome as Admiral Adama. The writers really fleshed out the whole Adama family dynamic. The new female StarBuck and Boomer characters were fantastic too. Speaking of campy, I've avoided those shows that were not really "hard SciFi." Which shows am I referring to? Here's the 1960s short list: Voyage to the Bottom of the Sea, Time Tunnel, Land of the Giants and Lost in Space. I can't list anything in the 1970s as there was no new SciFi TV to speak of! The 1980s and 1990s were great due to Star Trek, StarGate and The New Outer Limits. Here's a more recent short list: Hercules, Xena and Legend of the Seeker. Of all these campy series, only Seeker is FREE? Actually, I don't mind Lost in Space so much as I like Billy Mumy who was also in Twilight Zone, Babylon 5 and even TNG. The jury is still out on the likes of Dark Shadows, Night Gallery, Dr. Who, Space 1999, DarkSide, SeaQuest DSV, Quantum Leap and Farscape. Note: the Space 1999 and DSV links are not Kindle links and DarkSide is the only series I couldn't find on Amazon.

5) Crusade, 1999, $1.99 per episode on Kindle Fire
     I remember meeting Joseph Michael Straczynski at I-CON years before he started work on Babylon 5 in earnest. He had some mini screen plays and short stories about the space station that he read at the con, but that was about it. I could tell right away that Michael was very talented and was going places! His stories, his world and his characters were nothing short of genius. Too bad Babylon 5 was cancelled early! Yup, you heard right. Michael had fleshed out a 5 year story arc which was very dense. However, the original network, PTE: Prime Time Entertainment which aired on WOR Channel 9 in NYC, cancelled Babylon 5 after only 3 seasons. Luckily, SciFi (not yet SyFy at the time, don't get me started) picked up the series but only for one more year. So, Michael had to condense the last 2 years of his story to 1 year. I still don't know how he did it. Maybe that's why he still had material left over for Crusade? I almost didn't get to see the pilot episode of Babylon 5. At the time, cable TV was not yet that common and I was on rabbit ears (google it). So, I was waiting with baited breath for the long awaited pilot in February of 1993. Wouldn't you know, that was the same day that the World Trade Center was bombed for the first time? Darn terrorists decided to load up a MiniVan with exposives, park it in the subbasement and blow it up. Luckily, that did not bring down the towers but 6 people were killed and many more were injured. So, neeless to say, power was out in the building and the antennas on the roof were not serving up Channel 9 that night. I was actually able to watch the pilot in March when they re-aired it which was not usually done. The link above is of a great episode with Michael York as guest star. York plays a traveler that everyone seems to think is delusional when he claims to be King Arthur. The only one who believes the story is G'Kar (youtube link) who is dubbed the Red Knight! G'Kar was my favorite character possibly because he was played by the phenomenal Andreas Katsulas. Bill Mumy was a regular star and Walter Koenig played a secondary character in the cast. Did you know that Walter, of ST:TOS Pavel Chekov fame, is soon to get a star on the Hollywood Walk of Fame?

6) StarGate: Universe, 2009, ALL Seasons FREE on Kindle Fire
     Thank goodness for StarGate. Of all the SciFi on TV, I think this is the one series to keep alive the spirit of wonder and exploration that was at the heart of Star Trek. The writers, characters and actors in these series were all grand! StarGate also had a lot of humor and references to other great series. The SG-1 link above is one such story about Major O'Niel's getting stuck in a 24 hour time loop with Teal'c at the base and all the funny problems they get into trying to unravel the problem. I especially like the treatment of the scientists in these series. The Atlantis link above is about two of my favorite scientists in the series. Dr Jackson from SG-1 and Dr. McKay from Atlantis work together when a hidden lab on Atlantis is discovered. Now that I think about it, there was a comical episode of Atlantis where McKay goes back to Earth to attend a conference during a short leave. Who does he encounter there but Niel DeGrass Tyson and Bill Nye (youtube link) playing themselves! There was even one actor there that was supposed to be Stephen Hawking in his iconic wheel chair complete with synthetic voice. That character was never shown from the front, so I don't think it actually was Hawking. It would not be unheard of that Hawking make such a cameo as he has done so on TNG.

So, as you can see, this is the best thing since sliced bread, don't you agree? The Kindle Fire with Amazon Prime is just like Youtube but for free full-length commercial products! I am all for free, online, on-demand, video streaming of all my fave TV series on any Flash enabled device such as a droid smartphone or tablet as well as any Linux or Windows PC.

Well, that's all folks. I hope you enjoyed my latest blog on Summer diversions. I know it's unusual for this blog to touch on genre related topics and hobbies and such. You can expect, however, a few more along this vein this Summer! Here's some other blogs I've written along similar veins:

Summer School Projects Become School Year Projects!

If you take a look at this post, you'll find an ambitious list of Summer projects. However, these projects have taken a life of their own. As these projects relate to courses I'm teaching this year, I think I'll make them year-long projects instead! 

Each project is ultimately related to a course I am teaching this year. My schedule this year is insane! I have 2 sections of preCalculus for Seniors and 1 section of AP Calculus BC plus 1 section of Calculus Research Lab every other day. In addition to this, I have 1 section of Computer Math and 1 section of AP Computer Science. After school, I meet once every other week with my Computing Independent Study class as well!


I will go nuts unless I think of these preps as 3 Math: preCalculus, Calculus BC, Calculus Research Lab; and 3 Computer: Computer Math, Computer Science A, Computing Independent Study. Organizing myself like this, I feel as if I only have 2 preps! This way of organizing my day comes in handy for Youtube Wednesdays. During my math preps I'll show one video and during my computer preps I'll show a different video. This way students that take both preps, of which I usually have at least a few, don't get bored! In fact, this is a bit atificial, as Computing Independent Study is after school and does not do Youtube Wednesdays. Also, some of the Math classes have aspects of Computing and some of the Computing classes have math content too! So, I think I'll break up my day as 2xpreCalc+Calculus for my math prep and Computer Math+Computer Science+Calculus Research Lab for computing prep.


So, what follows basically amounts to a "note to self." What else is new, this whole blog is just one big memory dump for me! It's a great resource as my memory is so bad....

preCalculus for Seniors (Math 4R-12) and EBay:
I'm updating my TechBooks for preCalculus. I reorganized them last year and added a ton of screencasts (TechBook Lessons or TBLs). I rewrote a lot of my TechBook Questions (Tests and Quizes or TBQs). Now, I have to finish my TechBook Solutions (solutions to all the Tests and Quizes or TBSs). Once, I get all this done, I'll have a new addition for EBay! I have TBQs and TBSs for my summer courses (College Algebra and Harvard preCalculus). I also have TBqs, TBSs and TBLs for my summer classes on Harvard Calculus I and Hardvard Calculus II in addition to my High School AP Calculus BC. Take a look at my EBay offerings on the sidebar to this blog.



AP Calculus BC (Math 5HBC) Improvement Plan:
Last year we started Multiple Choice Mondays to improve AP Calculus BC results. This went on for 20 weeks before AP week. The first week I gave a Part IA or Part IB and the second week I'd go over the test. We repeated this 10 times and had lots of MCQ practice. My students did better last year on the MCQs as a result. This year we started to offer a new course, Calculus Research Lab. This class is open to both AP Calculus AB and BC students who want to practice key Calculus concepts. We meet every other day in addition to regular Calculus class like a science lab. We approach the concepts of limits, derivatives, integrals and differential equations from a new prespective: Scientific Computing. We use an online Computer Algebra System at http://www.sagemath.org to investigate problems Graphically, Analytically and Numerically. We do this in class with TI-89s, but SAGE is so much more powerful. I think that PC based computing of this magnitude is the future of STEM education even in High School. Some colleges, especially engineering schools, do something similar with Mathematica, Maple or MATHLAB. SAGE is just as powerful but it is also FLOSS (Free Linux Open Source Software) too!


Calculus Research Lab (CRL) and SAGE:
As mentioned above, I'm using SAGE a lot more this year in all my classes, not just in CRL. I use SAGE exclusively in Computer Math and Calculus Research Lab. I will probably do a final project in AP Calculus BC and AP Computer Science relating to SAGE. I try to use it occasionally in preCalculus and AP Calculus BC. However, I can do so only in limited fashion as these students will likely need to know how to use Graphing Calculators next year, not to mention on the AP exams or final. 


Computer Math (CM) and SAGE:
Again, we are using SAGE exclusively in CM. I literally taught CM or something similar using BASIC from the 1975-1976 school year to 2009-2010 school year. We switched to SAGE and python last school year (2010-2011) and got a new textbook too. Take a look, http://www.skylit.com



AP Computer Science (APCS) and YouTube:
It is APCS's turn to screencast. All my screencasts on http://www.youtube.com/calcpage2009 are from my math classes. It's finally time to screencast APCS from Linux!



Computing Independent Study (CIS) and openMPI:
My Computing Independent Study students are off to a great start. We already reinstalled the whole PC Lab with Ubuntu 11.04 Natty Narwhal 64bit. Now we have to get openMPI up and running. Then we'll look at some number crunching and POVRAY or Blender!


Final Projects and Android SDK:
Final projects this year will involve the Android DSK and Eclipse under Linux for APCS. My math classes can play with SAGE. Computer Math will look at programming the TI-83.


Edmodo with Youtube, Slideshare, Pastebin and SAGE:
I started using Edmodo last year to share files with my students. Edmodo is very easy to use as its just like Facebook but its secure and private. I started hosting files on Slideshare (SmartNotes as pdfs), Pastebin (java code in text files), SAGE (python code for CM and CRL) as well as youtube (screencasts) anyday I have something new. Then I link these files to my Edmodo pages for each class. I've also been linking these files to my blog once a week for a weekly summary! I have found this a very convenient way to share files with all my students. I used to do this with an ftp site, but my math students never caught on, only my computer students appreciated sharing files that way. BTW, there's an app for that! Both the iTunes and the Droid markets have an app for Edmodo too! 


I hope that these projects inspire you to come up with some of your own! What do ya 
think?
