Every Hero Has A (usually radioactive) Story


Every Hero Has A (usually radioactive) Story


Summer Reading 2015 program theme is "Every hero has a story" so I grabbed some scrap paper and put superheroes all over our 7' display board, took a photo and turned it into an activity sheet for the kids next month: name the hero. Some are kinda hard (Nick Fury, Black Widow, etc.)

I was going to have each character do a word balloon (in the classic Comic Sans font) that hinted at their origin: 

Teenage Mutant Ninja Turtles-"I was a turtle that got irradiated in the sewer"
Hulk- "I was a scientist that got hit with radiation"
Thing-"I was radiated...I think...probably..."
Spiderman- "I was bitten by a radioactive spider"


It got boring with all the radiation, so I just went minimalistic:




I had fun with scrap/garbage pieces of paper I saved and made random super hero faces--and Cat Woman, who somebody pointed out was a villain, LOL! It was actually a complaint from my boss, whom I placated by doing a Bat Girl face (bottom center).









I had to fill Seven feet of display board, and I also took a picture of and made an activity-sheet for next month's Summer Reading Program weekly thing: Name as many as you can.


People used to be impressed with nuclear energy and hopeful of its future; then they were afraid of the nuclear bombs--now people seem to know nothing about radioactivity or nuclear particles or science in general...besides it's effect on spiders-and the men they bite!


And no, my facial hair was not totally inspired by X-Man superhero Wolverine, it was mostly inspired by the guy in Kiev whose photo shows up if you search "modern ukrainian cossack playing bandura" in Google/Images.

Anyway, I'm patiently awaiting for a delivery from United Nuclear to build my own irradiating Neutron Gun!

Neutron Gun




Neutron Gun



What's so neat about neutrons? Well, among other things they can have a direct impact on their environment. They can knock out atoms in a crystalline structure, it can eat away at metals-causing then to become brittle, or can knock enough atomic particles around to actually change one element into an entirely different one via a process called transmutation.

If you aim the neutrons at heavy water/deuterium ($10) can create tritium (for modern glow-in-the-dark watches and gun sights)...although it would take years and years to accomplish. By the way: tritium slowly decays into helium-3 which is what Geiger counter tubes (Geiger-Muller tubes actually) are filled with.

Back to the design I scribbled above:
Alpha particle hits the beryllium. The beryllium turns onto carbon+a neutron. The neutron hits the paraffin wax and does one of two things, it either: slows down and continues on its merry way, or it hits a nucleus of a hydrogen atom in the wax really good and that sends a proton zinging out.

A word about Beryllium safety...according the internet it's super-deadly. In real life it's used in golf clubs, spark-less hammers, copper-beryllium tools, non-sparking drill bits, DENTAL crowns and implants and all sorts of other common, everyday stuff. 

Hopefully some of this will cause my Geiger counter to click.  If that fails then hopefully a neutron will hit some of the boron sprinkled into the paraffin wax, which will zing out an alpha particle-which can't be seen by my current Geiger counter, but can be seen by my radioscope ($29).

Now, if I replaced the paraffin with more uranium the neutrons would change any U-235 into U-236 (fission!). The U-236 promptly explodes and send off THREE new neutrons which then do the same to more and more U-235 atoms until...well, until the U-235 runs out.

Now, any U-238 in the blob of uranium goes through a similar process and becomes U-239, which blasts of beta particles of all things (which are detectable by my Geiger counter) and it breaks down into neptunium (also number 239). The neptunium-239 zings off yet another beta and becomes plutonium (again, still number 239). The plutonium zings off, are ready for this: more stupid alpha particles! Just like the ones we started with like a billion sentences ago...of course, the whole plutonium end of this reaction is pretty rare: even in a nuclear reactor it would take days.

This is in contrast to the boron portion, which is easy; so easy that hitting boron's huge neutron capture cross-section had been likened to hitting a barn door (a barn is the unit of measurement for denoting the size of a capture cross-section). A single barn unit is about the same size as the cross section of a uranium nucleus...boron's neutron capture cross section is 3800 barns! That's for B-10, regular boring boron still manages 760 barns.

If I replaced the beryllium with aluminum foil the result should be the same. I could replace the uranium at the beginning of the process with any alpha emitter, alpha particles being identical to a helium atom nucleus (2 neutrons bound to 2 protons); although it's like helium-4, not the helium-3 mentioned earlier.

It's all a big circle: helium, uranium, plutonium, helium-3, neptunium, neutrons, neutrons, neutrons...and of course our friend boron.



That's enough boron talk for now. Meow!

I'm Opposed to Saturn...We All Are at the Moment

I'm Opposed to Saturn...We All Are at the Moment


At the end of May 2015 Saturn is at opposition which gives us the best and brightest view of it all year.

Here's a lousy afocal astrovideo I took of Saturn through my 9mm eyepiece and 8" Zhumell reflector telescope on May 23, 2015. The actual view was much better than the cheap cellphone could convey.






A cheap telescope will show you at least the ring, which with even the cheapest binoculars on a tripod will look like Mickey Mouse ears. Early astronomers thought it might be a moon on each side. I thought, "how could a ring look like two moons?" but I went out with cheap binoculars and lo and behold! It did look like a big circle with two smaller circular 'ears'.



A small 40mm tasco type should still let you see something. Jupiter is even easier because its bigger and almost straight west to the right of the moon.

Here's another video with a 2x barlow attached to the 9mm eyepiece, making it a 4.5mm with higher magnification. 




More zoomed in but darker and less crisp focus. Such is the physics of optics and light. 




A great free phone app for astronomy is SkEye...which you'll need because the planets move around quite a bit (planet is Greek for "wanderer").

I also feel elated after getting some cosmic photons in my eyeballs. 



"The universe as we know it is a joint product of the observer and the observed."

-Teilhard de Chardin


Good night and clear skies to you!

We must weigh the horror of war vs the horror of peace: Game Theory for the uninterested




We must weigh the horror of war vs the horror of peace: Game Theory for the uninterested


I like the idea of game theory, but I find discussions about imaginary parlor games used to illustrate game theory extremely tedious. However in a book by William Poundstone (cousin of comedienne Paula Poundstone, and a man routinely described as "The Smartest Man In the World") I found a description of a simple game invented by Martin Shubik.



Shubik's Dollar auction is simple, unlike the dice throwing, three-sided coin tossing, etc. contained in many of the theoretical exercises dreamed up by employees of The Rand Corporation:

1) The highest had to pay what they bid, but they get the dollar bill.
2) The next-to-highest bidder has to pay what they bid, but gets nothing!

A penny is bid for the dollar. What a deal! Someone else bids two cents. Eventually the bids reach 99 cents and $1. If the bids stop the 99 cent bidder will pay 99 cents for nothing. If they bid $1.01 they'll pay $1.01 but get the dollar being bid on so they only lose 1 cent!

The other bidder sees this and his even higher since a winning bid of up to $1.99 would result in paying a $1.99 but getting the dollar bill-meaning they'd only lose .99 cents, of the bidding stopped there the 2nd place bidder would pay $1.98 and get nothing-a loss of $1.98.

Throwing good money after bad, only in this game you're trying to lessen your losses by doing it. In real life you'd maybe pay your auto-mechanic a few hundred dollars more to hopefully fix the problem and not have to spend tens-of-thousands on a new car-which would be a win and not just a lessened loss...unless the mechanic bill reaches into the thousands (blown engine, ruined transmission, etc).

Routinely games like these were used as jumping boards for the theories of how to wage wars, how to "win" an all out nuclear holocaust, etc. In "Prisoner's Dilemma" relates a Dollar Auction moment when Saddam Hussein said, "Iraq's material losses are already so great that we must fight to the end."

The scary thing is that unlike most of game theory, in the Dollar Auction there is no mathematical way to prove what is the most rational way to play. It's a simple game that is hard to tell when someone is winning, or even what winning looks like.

Poundstone's book is actually a biography of John con Neuman, Game Theory and the issues surrounding nuclear war. It's filled with great tid-bits (even of you skip over the dice-throwing and amoral tic-tac-toe-like games).




Probability is really just plain old chance




“Probability is really just plain old chance.”        -Michael Logusz

"Gefühl ist alles name ist schall und rauch."-Goethe's Faust



This ties in with my last post about 1 = 0.99... and "common sense", "normal thinking", etc. versus mathematical theory and terminology. 


Probability merely studies abstract models and not real life! Probability is better understood sometimes as “possibly” or “more than likely” or “usually”. Chance!


Games of chance (gambling). The probability that I would never win at the slot machine approaches zero. Am I (and every other tourist in Vegas) a guaranteed winner? Nope, but the way some people approach probability in mathematics would make it seem so.


If you flip a coin the chances of heads/tails if 50/50.


If you flip a coin 99 times and get heads 99 times, the chances that the next time you flip the coin it will also be heads is still 50/50. Math deals with ideas, not necessarily the real world. 


My "monster toned" 1922 penny that I recently bought (with free shipping!). It sure is a beaut! If I it the "chances" are that it'll land on heads is 50% theoretically speaking. I just flipped it three times and got three tails in a row :(




For instance mathematicians deal with lines a lot. Their lines have no depth, breadth, width, etc. Engineers deal with lines in the real world: if you make a 1” hole in something and try to put a 1” peg in it, it will NOT fit! Engineers need to make the peg slightly smaller than the 1” hole to get it inside.


A common problem with CAD/CAM design is that people design things the ‘math way’ and do not take into consideration the width of the line they drew with a pencil—or with the computer. The result: parts are too tight and can’t go together.

So if (as discussed in the last post) infinities of nothing can still add up to something is there something analogous with chances? Yes: quantum tunneling. In many of my posts I reference radioactive alpha emitters, usually AM-241. According to "regular" physics it's impossible for a slow/weak alpha particle to break past it's barrier and be emitted. Impossible. Hmmm...according to quantum physics it's insanely rare. An alpha particle would have to bounce around three times ten to the thirty-first power! Almost no chance but still a nontrivial possibility. Schroedin and Heisenberg came up with the answers, alternating fixed time or the basis on their related equations...but that doesn't matter because of you read my other posts you'll see that I have a tiny piece of Americium-241 that blasts out so many "ultra-rare" particles every second of enough to irradiate old silver dimes and cause an amazing display in a radioscope (see later post "So you wanna see atomic particles with your own eyes huh? Part II").

Yes, something so rare it's impossible in regular physics but can easily be seen with some zinc-sulfide smeared on an eyepiece (radioscope / spinthariscope). Don't believe your eyes? Irradiate an old silver dime with AM-241 wrapped in aluminum foil: your Geiger counter will let you know you've done " The Improbable " a few zillion times over.

YES and/or No!

YES and/or No!

"There are two sorts of eternity, from the present backwards to eternity, and from the present forward." -Abraham Cowley

Yes!




An infinite amount of nothing adds up to something. I find it creepy that the above two numbers, 1 and 0.999999... are considered the same by mathematicians, but they are.

There are many more proofs of the above that are more complex, but you don't need them because 1 = 0.999...

Creeped out? Keep reading.


No!

Even more odd is Zeno's Paradoxes, specifically the one about a race between Achilles and the Tortoise. The wording is difficult so I'll put it a more digestible way:

If you walk halfway across a room, and then half of that distance, and then half of that distance... on and on forever (according to Zeno) two things will happen:

1) You will never reach the end of the room, and
2) You will never stop moving!


Zeno was Wrong because of the same thing that (sort of) explains 1 and 0.999... being equal: transfinite infinities. If the distances become infinitely small, so does the time to traverse them.


The infinities eventually add up to 1 (or getting across the room). 

Now don't you feel better about 0.999.... equaling 1? Me neither, but at least it takes the edge off so I can sleep.

My next post on probability/chance briefly goes into infinities of nothing adding up to the possibility of something big: quantum tunneling.

CLASSIC LEYDEN JAR



HARNESS THE AWESOME POWER OF STATIC WITH THE CLASSIC LEYDEN JAR




I built a Leyden jar in three minutes to produce sparks. I lined an old plastic 35mm film canister lined inside and out with aluminum foil. A wire runs from screw on top touching the inside foil. Another wire runs from outside foil to a gap almost touching the screw. Some thin pieces of wire are also on the screw and fanned out to act as static antennas. 

Hold a pvc pipe in a cotton cloth and with other hand rub pipe past antennas. Every stroke makes a loud spark between the wire and screw gap. Pvc and hand don't touch the Leyden jar. 


One strip of foil outside, one inside. Wire from inside foil almost touching wire from outside foil. Add frayed thin wires for static collectors to the inside wire.

Use solid-core wire for the inside and outside wires. Use multi-strand wire for the static collectors and unweave the strands and fan them out.

I made my little 35mm one a little fancier by having the inside wire go to a screw, which comes out of a hole in the cap of the film canister. The white thing is just a piece of wire insulation, with multi-strand wire untangled and fanned out to collect static. The foil and wires were attached to the foil and the Leyden Jar with Scotch tape only. The static collectors is just wrapped around the screw, but I put a nut on it just for kicks.

Here's a video it in action:





Tiny jar equals tiny spark. Imagine the huge spark you could get by lining a garbage can with foil! Even after a spark this tiny thing acts as a capacitor and still has stored electricity which must be discharged by touching the gapped wire to the screw or else you'd get a shock by touching it. 

Yes, bigger jar means bigger spark. How about more or thicker foil (the dielectric)? Well, what if instead of measly foil I filled the jar with salt water? I did just that with my next few Leyden jars:



It took me 10 minutes from walking in basement and starting building to getting sparks. It's easier on dry days with low humidity. Sine days I can get one spark per wipe. Some days it takes five or six. The larger the Leyden Jar, the more wipes it takes to spark.

The beast on the left is a daily water Leyden Jar. The spark takes a while to build up (lots of wiping the PVC with wash cloth) but it is larger and a lot louder!

Here is a scary, but true scenario: a battery slowly discharges it's electricity. Think of a flashlight. A capacitor discharges instantly. Think of a camera flash. In a non-existant "perfect" capacitor, the capacitor would fire instantly and emit 100% of its charge, leaving 0% energy left. 

However, in the real world dielectric relaxation causes a brief delay in the firing of the capacitor. Worse yet, dielectric absorption stops the capacitor from emitting 100%, meaning it stores a small amount above 0% after firing. In a regular dry capacitor there can be 3% of the charge left after firing. In a wet electrolytic capacitor the left over charge can be a whopping 15%!!! 

The result of all this? When the little, dry Leyden Jar fires it is pretty "empty" afterward. The wet, salt-water filled electrolytic Leyden Jars on either side can fire a huge spark, and then zap your hand with 15% charge if you touch them afterwards! Ouch!!

I can use the PVC pipe to force the in inside and outside wires to touch and get closer to 0% charge (there is a small spark when this happens) but even then, if left alone the charge can reorganize and zap a human hand when touching it!

Think of the tiny (yet much more efficient) capacitor in a stun gun. Then look at the salt-water filled behemoth on the left in my photo. I made a Leyden Jar out of a 1 gallon container: I fired it once and immediately disassembled it so no one would get hurt by it.



Every time I touch my back paw to my ear I get zapped! Too bad I don't have a tail: its dielectric absorption would give me stun-gun claws! Meow.

PAPER FOLDING MATH PEOPLE






PAPER FOLDING MATH PEOPLE




Score of a lifetime: library book sale had a pile of unwanted math books. So I buy them and when I get them home I see most belonged to noted mathematics author Leo F. Boron!

He authored books on math and translated many more. The best part besides his notes, signatures and ex-libris bookplate: a paper polygon tucked inside of one of the books. It's a regular pyramid made from green construction paper.

I also snagged a book once owned by noted University of Michigan professor George Kish. Is the third edition of Burlington's "Mathematical Tables and Formulas". The papers of Professor George Kish are now in the archives of the Bentley Historical Library in Ann Arbor Michigan...well, at least the ones that aren't on my bookshelves.

PAPER POLYGONS, BUILDINGS, CODE-BREAKING...





PAPER POLYGONS, BUILDINGS, CODE-BREAKING...

...IT'S GONNA GET A LITTLE WEIRD


People ask me what I enjoy. There are many answers but they boil down to books, optics, science and patterns. Before I could read or write I was a graphomaniac: I would scribble and scribble and scribble on paper and then fold and refold and crinkle and smooth pieces of paper. A little piece of paper can become an entire world. Whether you write a story or fold it into something dimensional.

What follows zings around quite a lot. As far as a post it's like a lot of posts mashed together. If any of the math, etc. bores you scroll down a little--it changes up.

This really should have been my flagship post for Science & Optics, but was too chaotic.



A stella octangula!





 Also called a stellated tetrahedron. Father Magnus Wenninger (cute pic of him in his office/cell filled with paper models: http://www.saintjohnsabbey.org/wenninger/) would be proud-actually since he literally wrote the book(s) on paper polyhedrons (I’ll be getting his book free with all the Chase/Amazon points I earned buying suits for work: http://www.amazon.com/Polyhedron-Models-Magnus-J-Wenninger/dp/0521098599) he’d just politely smile (he is a monk, priest and mathematician. 

Stella octangula is compound (the shape repeated-then turned (roll your own: http://mathworld.wolfram.com/StellaOctangula.html). When I need to take a break or mull an idea over I’ve decided to make a polyhedron (or other paper shape). Wenninger came up with 75 main paper polyhedrons for his first book—but the publisher demanded he make and photograph them all before they sign a contract. He did it.

I think I’d like to repeat that feat: like the author of ‘Baking With Julia’. That could be my ‘hook’—although resources on the web reveal people who have done all 75 plus tons more shapes (this is one of my favorites, click on a shape to get the folding instructions, some are easy-some I’d only attempt if I was laid up in bed with two broken legs: http://www.korthalsaltes.com/).

I thought of making a bunch of these and leaving them around work as a mystery-but my boss (who’s also a friend) saw one tiny one and instantly knew it was me; I mean *who* else would leave something so odd behind in the library. I did see a mixed up Rubik's Cube on a professor's desk and quickly solved it at about 9:30pm. I never told anyone that. He must have just walked in and wondered who solved it for him. 






By the way, I made my first paper polygon at work. My job left me alone in our library until 10pm. I also worked mornings on Saturdays. Saturdays were very mellow (usually) and I had time for experimenting with secret little paper foldings. It was very peaceful.






The 5 Platonic Solids and a few other, slightly more exotic paper polyhedrons that I made for a math display table for library help/tutoring. If you do something you like-bring it into your work if you can.









Twisted pyramid. The shape to the left is a great representation of a crystal mineral shape. I collect minerals and I've grown crystals in the past. This site provides paper diagrams for folding complex (and many times non-symmetrical) crystals out of paper : http://webmineral.com/help/Forms.shtml which is just awesome. There's a similar one called 'The Great Icosahedron' that I may make next, Charlie Brown!








This bad boy has a removable cube hidden inside! I made this about 20 years after I made my art boxes for a three dimensional design course at Wayne State University.







I got interested in how the big ball bearing (convex) looked like a concave dish when looked at through the pipe hole, but like the (real) sphere from the side. Little worlds with weird optics.




Shapes moving and transforming also interest me.




The above video (11 secs) of me inflating a rounded-cube-polyhedron super-ellipsoid origami thing. Basically a cube with bulged out sides. Colorized it in Windows Live Movie Maker so it would be less boring. These are, in a weird way, kind of like the ever-changing flexagons (little paper math machines, kind of like flat paper Rubik's Cubes) which I'll cover in another post. Folding carefully--and then blowing into a corner inflates the shape with no visible holes.







I've always enjoyed patterns. During my Fine Arts undergraduate stay at Wayne State University I made a couple 8mm films and lots and lots of photographs of patterns in nature (flowers, rain, snow falling, boiling water close-up, wrought iron, things through a home-made macro-bellows high magnification system, etc.).






Years ago I used some spare lenses out of a broken CD player to make a magnifying diopter for the front of my camera. I make close-up photos of security paper with it. Security paper has patterns like the above printed inside envelopes (so you can't hold it up to a bright light and see the check inside) or printed on checks or other documents to make reproducing them (counterfeiting) much more difficult. 

I have a file (and photographs) of hundreds-upon-hundreds of security paper motifs like the one above.








Much like Iron Man gets his magic powers from, uh…actually I can't remember what his deal is…anyway, the rain gives me complex barometric migraines *and* Master-Level Chess playing ability! Also I have a chess dictionary on my desk. 9 moves and I smashed the computer at level 2000 with my ‘Wall of Pawns’ strategy! Basically through simple patterning I've solved the problem of chess: no one ever need play it again. Actually this strategy worked a few more times then I think the game ‘learned’ and I went back to being terrible at chess. I get caught up in the patterns of the moves.



I even see patterns in my coffee!





Patterns in the clouds over my house! Patterns tend to signify things. Science explains those things. 


From an early age I was exposed to Psanky (wooden Ukrainian Easter eggs) and highly patterned textiles in the form of kilim rugs. These are just a few--I have almost 100 psanky.






My Typewriter Art: Fourth order Magic Squares increasing by sums by 4 (except the second one which is just the first re-ordered). Sums of each horizontal, diagonal and vertical row or column are the same within each square. Essay Onion Skin paper. I started doing these in the 1970s on an early electric typewriter. This is a much later one from 2010, inspired in part by an old Manuel Morschopoulis style I typed up years before I started dating things:



I just discovered this trial magic square tucked into a box of Eaton's Essay Onion Skin typewriter paper (my favorite). I must have found it in 2010, used it to make the previous math square art and then tucked it away and forgot about it.





I also make scribble drawings...but with one big rule: It's a single line that cannot touch! I've done hundreds of these in boring lectures, waiting rooms, etc.





My paper buildings span from ancient obelisk, to a farmhouse, German guesthaus, 19th century bridge, 20th century skyscrapers and ultra-modern clock tower from Dubai. Why? Why not! Extreme right: Grand Rapids Amway Grand Plaza Hotel and the Renaissance Center Building. My favorite is still the Seagram Building (center/black). At center is the famous Dubai Clock Tower (thing that looks like a white spider). They're a simpler (usually) version of the more advanced paper polygons...plus they're cute!




It's the Zur Glashütte Guesthouse in Crottendorf Germany. So tiny. So cute!




Skip down to the kitty if the following math blurb bores you.



When Grigory Perelman gave his lecture solving the Poincaré Conjecture he visualized a drop of water rolling downhill: it was a variously curved surface, but in places as it rolled it could break off or close completely. He got rid of these pinches by using mathematical tricks—but what if the universe wasn’t a repeating non-infinite sphere, or a torus (donut shape), but a blob-with another blob that was separated by ‘non-existence’ that was unreachable from the blob we’re currently inside (torus, 3-sphere or other)? If you flew in a space ship off the edge of one blob, you’d show up at the opposite side of the same blob-never entering the other blob(s). Kind of like the game Asteroid where you fly off one side of the screen and show up on the other side (you’d never make it onto your neighbor’s TV screen). 




If any loop can be shrunk to a point on a manifold sphere-then it is ‘simple’; a 3-sphere, like the Earth or a tying a string around a greasy watermelon: the tighter you pull the knot, the more it slips down and off—making a single point (the knot off the watermelon); meanwhile if you try it with a torus (think donut) and you tie it around the center you can make a donut necklace, and no matter how tight you make the chain, the donut will not slip off, unlock when you try to tie a chain around a baseball or watermelon or other spheroid-thus the torus is not simple. There was ONE historian who LIED and said that people thought the Earth was flat; untrue, for over 3000 years people have known the earth was roughly spheroid. 

The argument Columbus had about going around the world was NOT about falling off the edge-it was about who big a circumference he’d have to navigate: Queen Isabella’s people thought anywhere from 18,000 miles to 26,000 miles around (it’s a smidge under 25,000 at the bloated equator). Now, if you took every available map of the Earth at the time you could assemble them into a sphere (paste the flat paper maps onto a globe), but you could have also pasted them onto a Torus (donut shape) or a globe that looked a bit more like a pear-in fact our Earth bloats out at the equator due to centrifugal/rotational force, much like how a dragster’s rear wheels get all elongated and huge vertically when the drover whomps on the gas. Columbus worried that at the top of the pair the circumference was less than the bottom of the pear—and thus run out of supplies on his voyage. Columbus worried about a smart thing--not the dumb thing your teachers thought.



Okay, wake back up: the fancy-smanshy maths are over!!!!!!!! 

BTW, The cat is called Harbooz which is Ukrainian for melon, watermelon, cantalope...she is very jealous if anyone carries a melon into the house and must be calmed by cradling her just like she was a melon being brought in with the rest of the groceries.




Patterns and little private worlds in paper, math, writing, coding, etc.



I've written about patterns and also creating little worlds. 


This is my train set, it's T-Gauge. T = 3mm between the left and right wheels (axle length). It is 1:450 scale. This is not to be confused with TT-Gauge which is way bigger! 






There are little people.




There are even smaller people.




These are (huge by comparison) Z-Scale train people next to a penny.




So tiny.



I used them to create a paracosm: a very detailed imaginary world in your mind. Only I made mine with digital photographs and little train people and household objects. 




Above is my favorite in my Paracosm Series: the huge head/idol is about the size of a tennis ball. It was a failed/practice mold in Plaster of Paris I made from some architectural salvage I was reproducing. Kind of an Indiana Jones sort of feel. I get the same feeling from playing with patterns and math and science, etc.





TRULY SECRET WORLDS: CRYPTOGRAPHY



 

People are encrypting the dumbest things these days-but it's always fun to hit the button and feel like James Bond, if only for a second. Cryptography (and decoding) follow algorithms and patterns. I've kept notebooks since getting a secret code book (which I still have) as a very young child.




In 1401 the Duke of Mantua Leon Battista Alberti invented a frequency blurring cryptographic algorithm. In 1999 two books were published with an error in the plaintext portion of that code. Tonight I found *both* of them. Basically an 's' was were a '5' should have been in the ciphertext, so that the word "Deepfreeze" was decoded (by me) as "Neepfreeze". 





Frequency blurring is where a letter can be coded as more than one symbol:

t = x, 
q or 3; 
h = y, 
i or 9; 
e = z, 
m or 22



This way you can just count the number of times a symbol was used and match that to a simple chart of English Letter usage frequencies (where 'e' is the most used letter, etc.). I've already broken 3 other codes in these books using simple frequency counting. You count the usage of the symbols and list them from most used to least and then line it up against the English (or whatever) frequency chart--in single substitution it's usually only 1 or 2 letters off and very easy to decode.


ASINTOER (a sin to err) are the most frequent letters, along with 'the'. If you only substitute each letter of your plaintext with one single ciphertext (t = x) then the code may be easily broken by looking for groups of three letters (xyz) and assuming they are the word "the". Also, the most frequent letter 'e' is probably what the most frequent ciphertext letter (or symbol) is. x=t, y=h, z=e. You count the frequency of every letter/symbol in the code and then work asintoer/the/of/a/I/etc-the frequency of letter/word occurence in English (and other languages) is known and available in simple charts.



Not surprisingly, when I was an undergrad at Wayne State University and spending lots of time in their photographic darkrooms I got interested in spy cameras, properly called subminiature  cameras. I also always wanted one since seeing (what I think was) a Minox subminiature spy camera being used in an episode of Laverne & Shirley. I think they were trying to steal the secret recipe from a rival brewery or something. LOL!






Anyway, as you can see above-I got a Minox spy camera. It's from the Cold War Era. The bumps on the chain correspond to settings on the focus dial. You put a document on a desk; hold the camera above it; count the bumps and set the focus dial to the corresponding settings: easy copying of top secret documents! This is the famous camera that advances the film by holding it like a pair of binoculars and pulling/pushing on the left and right sides: click-click. It is a fine piece of machinery, like a Rolex watch. I even obtained a film slitter for it to cut 35mm film down to 8.5mm size.








This is a teeny-tiny subminature camera from the Cold War era. It came with a dozen rolls of 8.5mm film. Penny shown for size. Nice faux-alligator leatherette covering. I like how the (original!) box seems to imply that, 'yes, you too can create something as colorfully saturated and blurry as the Zapruder Film!!!" Actually it seems to show an Asian car stopping at a security gate. It i very light and cheap feeling but cool. It's like a neat digital watch versus a Rolex.


At some point I'll post about: my crystal radio sets made with old razor blades and pencil leads (I even made my own pencil after reading a book about the history of pencils); shortwave radio, CBs and my Rubiks Cube and Knock-off Rubik-like puzzle collection.




 

Well, that's the tail end of the snake--good night!
