How to Keep that Christmas Tree Fresh

Washington State horticulture professor Linda Chalker-Scott, has a podcast “Last minute advice about Christmas trees and other fun stuff” that details more than you’ll ever want to know about how to keep a Christmas tree fresh in the house. And, yes, it’s been studied. Apparently WSU has a Christmas Tree expert: Dr. Gary Chastagner, seen above counting dry needles.

Happy Winter Solstice!

It is the darkest day of the year, and the shortest day of the year.  But from now on, every day will be a little longer and a little brighter, until the year turns once more. This is a rough time to be a gardener, even in Southern California. Everything seems to be sleeping. You, perhaps, wish you were tucked in a warm bed, sleeping, instead of frantically rushing getting ready for the holidays.

As a counterbalance to Erik’s gloomy Apocalypse post, I’d just say that the Winter Solstice offers us this annual lesson: there is a dawn after even the longest, darkest night. And then things get better.

We may be facing many challenges right now, as individuals, as a nation, as a global community, but we’ll get through them. We always have, we always will.

Things will change, no doubt about it. The future will not look like the present. As Heraclitus reminds us, Everything flows. But life is always made up of equal parts joys and sorrows, no matter when, or where. So whatever winter festival you celebrate, take joy in it. Get together with the people you love best. Burn some lights against the darkness. Keep each other warm. Eat something delicious.

Our best wishes to you all! Thank you for your love and support.

Zombie Apocalypse Poll

Despite the jokey title of this blog post I’m seriously interested in hearing where our readers are coming from regarding our future economic/social situation in 2012. To that end I’ve crafted a poll that you can find on the right top side of this blog. The poll closes on the 31st and I’ll post the results in the new year. Feel free to also leave a comment below. What is your outlook for 2012?

How to Memorize Numbers

Giordano Bruno’s insanely elaborate memory system.

Yesterday we introduced an ancient memory system that can be handy for learning all those new urban homesteading skills. Today I’ll briefly discuss a way to use a related mnemonic called the Major System for committing strings of numbers to memory.

To use the Major System you first memorize a set of consonants that represent 0 through 9. From Wikipedia, here’s a table of the Major System consonants and a set of mnemonics with which to remember them:

Numeral Associated Consonants Mnemonic
0 s, z, soft c “z” is the first letter of zero. The other letters have a similar sound.
1 d, t d & t have one downstroke and sound similar (some variant systems include “th”)
2 n n has two downstrokes
3 m M has three downstrokes and looks like a “3” on its side
4 r last letter of four, also 4 and R are almost mirror images of each other
5 l L is the Roman Numeral for 50
6 j, sh, soft “ch”, dg, zh, soft “g” a script j has a lower loop / g is almost a 6 flipped over
7 k, hard c, hard g, hard “ch”, q, qu capital K “contains” two sevens
8 f, v script f resembles a figure-8. V sounds similar. (some variant systems include th)
9 b, p p is a mirror-image 9. b sounds similar and resembles a 9 rolled around
Unassigned Vowel sounds, w,h,y These can be used anywhere without changing a word’s number value

So, for example, to memorize the number “1795” you start with the first two numbers “17”. Let’s say 1 = “d” and 7=”g”. Next add a vowel of your choice, say “o” to make “dog“. “17” now is a dog.  For the 95 let’s say 9 = “b” and 5 = “l” to make “ball”. You now have a dog playing with a ball that you can put into a room in your memory palace. For a longer strings of numbers it’s best to “chunk” them into groups of four to make them more manageable.

This is beyond the amount of time I’m willing to put into this, but you can also commit to memory 100 images to represent double digit numbers between 00 and 99 to be able to memorize longer numbers faster.

The Art of Memory

We need a term for superfluous smart phone trivia Googling. After all, with the vast archive of factoids on the interwebs who needs to remember anything anymore? But what do we miss by externalizing all of our memories into an electronic form.  What about those bards of the past who could recite thousands of lines of poetry, or the Greek rhetoricians who could speak for hours at a time without notes? Thankfully the basics of the lost art of memory can be mastered in an evening. And  it’s all in a short section of a 2,100 year old document called the Rhetorica ad Herennium.

Here’s the memory trick the ad Herennium describes in two easy steps. Step one. Say, for example, you want to memorize the following shopping list: goat milk, goat milk yogurt, two blocks of tofu, olive oil, sunflower seeds and cat food (tuna). Take these items and imagine them in some memorable way. Think crazy, surreal, obscene etc. As the ad Herennium puts it,

When we see in everyday life things that are petty, ordinary, and banal, we generally fail to remember them, because the mind is not being stirred by anything novel or marvellous. But if we see or hear something exceptionally base, dishonourable, extraordinary, great, unbelievable, or laughable, that we are likely to remember a long time.

Step two. place the images you’ve imagined into a physical space that you know well, say your house, your childhood home, office etc. You are, as the ancients would say, creating a “memory palace”. For my shopping list I used our house and imagined a goat in one bay of the garage (goat milk), a goat operating a soft serve yogurt machine in the other bay (goat milk yogurt), two giant cubes of tofu jumping up and down in the living room, Olive Oyl from Popeye in the kitchen (olive oil), Mrs. Homegrown munching sunflower seeds in the hallway (sunflower seeds) and cats dancing around a fish in the bathroom (cat food). When I used my memory palace at the store I was able to recall all but one (olive oil). Later I realized why. I was never really into Popeye and, as a result, using Olive Oyl was not sufficiently memorable. I later came up with a much more graphic way to remember the olive oil later, but this is a family friendly blog so I’ll forgo the description. Even though this banal shopping list is almost a week old I was able to remember it for this blog post. And one of the great features of a memory palace is that you can recall your list in any order by simply walking through the imaginary building you’re using.

While I’ve got the basic concept of the art of memory I need to do some more practice. So far what I’ve found it most useful for is learning people’s names. And, as an urban homesteader, I always find myself learning new skills some of which require memorization. Now this won’t help you find a lost set of car keys. That’s what the ad Herennium calls “natural” memory which it distinguishes from the “artificial” memory that can be enhanced with a memory palace.

I wish this handy trick had been taught to me in school. You can get the idea across in just a few minutes. While we don’t want education to devolve into rote memorization, it’s a little embarrassing to think about how much memory we’ve ceded to the Internet in the post-iPhone era.

The art of memory is a right brain, creative activity that exercises creative visualization. It’s a tool that Renaissance mages such as Giordano Bruno and Giulio Camillo used to initiate the shift in consciousness that gave birth to the Renaissance. Francis Yates’ book The Art of Memory describes the role memory techniques played in this shift. The revolution in thought launched by Bruno and Camillo gave us the wonders of Western science and, ironically, the iPhones that have externalized our memory palaces. It’s time to re-aim that consciousness and we’ll do so by constructing new memory palaces, even whole memory cities and landscapes. To paraphrase the emerald tablet, beloved by Bruno, “As within so without.”

We’ll go over a mnemonic system for numbers tomorrow.
