Three Riddles

by Jonathan Swift

In Youth exalted high in Air,
Or bathing in the Waters fair;
Nature to form me took Delight,
And clad my Body all in White:
My Person tall, and slender Waste,
On either Side with Fringes grac’d;
Till me that Tyrant Man espy’d,
And drag’d me from my Mother’s side:
No Wonder now I look so thin;
The Tyrant strip’t me to the Skin:
My Skin he flay’d, my Hair he cropt;
At Head and Foot my Body lopt:
And then, with Heart more hard than Stone,
He pick’t my Marrow from the Bone.
To vex me more, he took a Freak,
To slit my Tongue, and made me speak:
But, that which wonderful appears,
I speak to Eyes and not to Ears.
He oft employs me in Disguise,
And makes me tell a Thousand Lyes:
To me he chiefly gives in Trust
To please his Malice, or his Lust.
From me no Secret he can hide;
I see his Vanity and Pride:
And my Delight is to expose
His Follies to his greatest Foes.

All languages I can command,
Yet not a Word I understand.
Without my Aid, the best Divine
In Learning would not know a Line:
The Lawyer must forget his Pleading,
The Scholar could not shew his Reading.
Nay; Man, my Master, is my Slave:
I give Command to kill or save.
Can grant ten Thousand Pounds a Year,
And make a Beggar’s Brat a Peer.

But, while I thus my Life relate,
I only hasten on my Fate.
My Tongue is black, my Mouth is furr’d,
I hardly now can force a Word.
I dye unpity’d and forgot;
And on some Dunghill left to rot.

The “slit tongue” reference might seem odd today, but it comes from an ancient theory about making some birds “talk” as explained by John Marzluff and Tony Angell in the book “In the Company of Crows and Ravens”:

BaaCode for Icebreaker Clothing

Icebreaker is a company that makes wool clothing. They provide a page where you can enter a code from your clothing to find out all kinds of information about its “source”:

Your unique Baacode will let you see the living conditions of the high country sheep that produced the merino fibre in your Icebreaker garment, meet the farmers who are custodians of this astonishing landscape, and follow every step of the supply chain. We’re sure you’ll find the experience as inspiring as we do. Enjoy your journey back to the source.

“Traceability” seems like a really good way to get a handle on the information that has to be displayed on packaging like sulfur, or nuts, or types of sweeteners. The use in garments is nice too, but seems more like a novelty than a necessity.

I wonder if anyone has invented a device that could scan a barcode, identify the product and then immediately advise whether the contents and/or source is suitable for purchase. That could save shoppers significant time/effort and help drive change in the market.

On the flip side, I wonder if Icebreaker monitors who checks their BaaCode and from where.

The demo code they offer for testing is 213C3F390 and the URL seems to support automated/scripted testing, like this:

https://www.icebreaker.com/site/baacode/trace.html?language=en&baacode=213C3F390

How long before someone runs every alphanumeric and downloads their database? Maybe there’s no threat. I mean what could anyone do with a database of wool fiber supply chain information? Could suppliers use it to reveal competitive info and set prices?

Degrading Plastic

A story from last year’s TheRecord.com explains that plastic can now be degraded by natural microbes at an impressive rate. The solution? A high school student figured out he should isolate the most productive strains by testing them on plastic bags.

He knew plastic does eventually degrade, and figured microorganisms must be behind it. His goal was to isolate the microorganisms that can break down plastic — not an easy task because they don’t exist in high numbers in nature.

First, he ground plastic bags into a powder. Next, he used ordinary household chemicals, yeast and tap water to create a solution that would encourage microbe growth. To that, he added the plastic powder and dirt. Then the solution sat in a shaker at 30 degrees.

After three months of upping the concentration of plastic-eating microbes, Burd filtered out the remaining plastic powder and put his bacterial culture into three flasks with strips of plastic cut from grocery bags. As a control, he also added plastic to flasks containing boiled and therefore dead bacterial culture.

Six weeks later, he weighed the strips of plastic. The control strips were the same. But the ones that had been in the live bacterial culture weighed an average of 17 per cent less.

That wasn’t good enough for Burd. To identify the bacteria in his culture, he let them grow on agar plates and found he had four types of microbes. He tested those on more plastic strips and found only the second was capable of significant plastic degradation.

Next, Burd tried mixing his most effective strain with the others. He found strains one and two together produced a 32 per cent weight loss in his plastic strips. His theory is strain one helps strain two reproduce.

The risk of plastic now has to be recalculated.

La Steaua – To the Star

by Mihai Eminescu

La Steua care-a rasarit
E-o cale atit de lunga
Ca mii de ani i-au trebuit
Luminii sa ajunga.

Poate de mult s-a stins in drum
In departari albastre
Iar raza ei abia acum
Luci vederii noastre.

My translation:

To the Star that rises
So far away
Many thousands of years
before we see the light

Perhaps it disappeared already
In the blue void
But only now it appears
shimmering in our eyes
