		<description>I have three different cameras with different number of frames on a roll of film. My Leica M3 will give 36 frames per roll, the Roillei 12 frames per roll and my Hasselblad xpan 20 frames per roll. 

I will mainly use my M3 so I'll probably shot and print 1000 pictures - frames.

It is like practicing a musical instrument. It won't make me brilliant but it should make me proficient; you know my Joe Lewis quote. 

I'll develop several rolls film together; anywhere from three to seven rolls at a time. Printing will take longer; even if I go for acceptable fast prints in a week I'll be doing about 250 prints.

i shot my first roll yesterday; and today I'm going out in the rain and shooting my second roll.</description>

		<description>MICHAEL,

ABOUT 20 YEARS AGO, AT AGE 50, I UNDATED AN UNDERGRADUATE DEGREE IN MATHEMATICS WITH A 6 MONTHS STUDY ON THE HISTORY OF ZERO. 

The average math history book says that zero first arrived in Germany around 1200 AD and slowly was added as a place-holder in our base 10 decimal system, as you know that date was 1585 AD (Stevins, and some say Napier). 

Such a summary omits the Greek, Babylonian and Egyptian practical use of a zero, with the Greek symbol, topped by two dots, finding its way to India, and 800 AD return to the Arab world, and finally to Fibonacci in 1202 AD in the Liber Abaci.

Zero was well known and used in a wide array of  Ancient Near East cultures, and used positional in Mesoamerica, well before Europcentric folks wished ownship of the theoretical properties of zero just 400 years ago.

Is this the type of review that you were wishing to see?

Milo Gardner

ps - my personal blog posts occur when updates to story lines come to light. In the last few weeks my undergrad minor, history of economic thought, was upgraded by linking to the oldest theoretical Western math thread, money and commities, as linked to my Wikipedia page (as cited yesterday)..

Thanks for the thoughtful comments.</description>

		<description>This sounds interesting!  It's almost like a musician practicing every day, isn't it?  Well, maybe not exactly the same.  Will it be too hard to do?  Does it take a lot of time to develop a roll of film?  How many photos would that be?</description>

		<description>I read the 'correction' in the Times and they are still getting it wrong.

The discussion of levers reminded me of the Leonardo di Vinci exhibit that I saw in the World Financial Center several years ago. It was amazing.</description>

		<description>Milo, you post to your blog less than I post to mine! They are interesting posts!


What about the history of zero?</description>

		<description>The April Fools joke, noted this week, continues to be parsed.The false assertion that Greeks al most always began with practical ideas and then proceeded to create theoretical models, as discussed in terms of ARCHIMEDES and mechanics has been repeated far to long.  The reverse was true more often than not!

For example,  2,000 BCE Egyptians and Greeks began with theoretical models, such as a hekat unity (64/64) and created practical mathematics (dividing by any rational numbers) that measured every difference between expected and actual result (in exact quotients and remainders), as the Akhmim Wooden Tablet repoorted, and Archimedes proved his lemma that:

4A/3 = A + A/4 + A/16 + A/64 + ... (infiniite series)

was exactly measures by:

4A/3 = A + A/4 + A/12 (finite Egyptian fraction series), the beginning notion of ancient calculus.

The same theoretical and abstract beginning point was extended to Egyptian farming, allowing absentee landlords to manage from afar, as discussed and linked in the third paragraph of:

http://egyptianmath.blogspot.com

Thank you all for considering these additional Ancient Near East corrections.

Sincerely,

		<description>You're right! I was so busy trying to visualize the distance between the gunwale and the rowers hands that I didn't remember that the fulcrum is not the oarlock! 

&lt;a href="http://www.oarsport.co.uk/training/guide.php?article=rigging1" rel="nofollow"&gt;Here is a nice url explaining how an oar as a lever works.&lt;/a&gt;

I wonder if the &lt;em&gt;NY Times&lt;/em&gt; will get around to explaining their mistake; or MAYBE it was an April Fools Joke.</description>

		<description>The article leaves a lot to be answered.  Classics professors (even at, gasp!, Harvard) aren't the best source of info on this sort of thing.  For starters, the full length of the oar is the effort arm, as the water -- not the oarlock -- is the fulcrum (much as with a wheelbarrow).  The oarlock, attached to the ship, is part of the load.   It goes downhill from there.</description>
