04/15/13 - The Science of Middle Earth

Science is learning all sorts of new things about the earth, particularly about hot plumes rising from the mantle and creating islands in the Pacific and splitting continents. For the latest, we checked out the April 5th, 2013 issue of Science Magazine, the journal of the American Association for the Advancement of Science:

"Plumes of all sizes seem to rise from two huge piles of who-knows-what sitting 2900 kilometers down at the bottom of Earth's mantle embedded in a mystery layer hundreds of kilometers thick. The outline of an operating manual is coming into view, but some pieces of the Earth engine are yet to be labeled."

We are definitely on the frontier here. Let's face it: no one knows what; it is a mystery layer. That's real science.


The plumes are under the redder areas. The mystery layer is inside somewhere. No, we don't know what.

01/18/13 - Lissajou Figures

If you ever watched any science fiction movies from back in the 1950s or 1960s, before modern computer generated special effects, you almost certainly have seen a Lissajou figure, a strangely wobbly figure traced on an oscilloscope screen. They were one of the weirdest things you could make appear on an oscilloscope screen without a great deal of trouble. All you needed were two signal generators, and there you were, in science fiction land.

There are a number of Lissajou figure generators on the internet, but most of them require Java. Right now Java is having its own special effects crisis as a security risk, so it is time for a replacement. This generator uses HTML5, so it will run in most newer browsers, though it may not run in some older ones. Click this link and go play. There are two parameters, generally small integers, you can adjust, and you can drag your cursor across the phase shift rectangle to make the figure "rotate". It's a spacey effect. Sometimes it will appear to be rotating horizontally, but if you tilt your head you will see that it is rotating vertically as well. (Try 5, 4 for that.)

12/31/12 - Two Out Of Four

This was a last minute Christmas present suggested by most recent flight back from Seattle. The climb out of Boeing Field takes one over an industrial area south of Seattle. It doesn't look like much by day, but there are all sorts of fascinating lights by night. One set was hypnotizing, a set of four columns lighted two at a time, moving about an invisible shape. A quick trip to the Radio Shack provided an Arduino processor and some red LEDs. JoAnn's fabrics and hobby supplies next door provided four plastic columns for supporting elaborate wedding cakes. Add in a glue gun, a soldering iron and some black foam board, and there was something new under the tree. Be sure to click and watch the dark video. It can be hypnotic.

06/18/12 - We Answer Questions - Operation Twist

Now and then we get questions from our friends and family, and we try to answer them. Here is our answer to two related questions: What are bonds? and What is Operation Twist?

1) Bonds are just loans. If someone, usually a company or government entity, wants to borrow money, they can write down promises to repay in the form of bonds which are legal documents, contracts, that state:

  • a) A certain sum must be paid on a certain future date
  • b) Certain sums of interest must be paid at certain intervals
  • c) The borrower may repay the loan early, but not before a certain date, the call date
  • d) This is a contract since a, b & c are because the borrower received a certain amount when the bond was issued.
A bond is a fungible instrument. It can be bought and sold. Typically, the borrower engages a bank or other financial firm to serve as the underwriter. The underwriter is responsible for rounding up the money to be lent. Underwriters usually have clients who are looking for investments, so they'll typically arrange to sell their clients a lot of the bonds before the issue date, the day the borrower gets the money and the lenders get their bonds. Even they can't sell enough bonds, the undewriter is still obligated to lend the full sum, so they try and sell as much of the loan as they can up front.

A lot of financial instruments use the same structure. If you buy a CD at your bank, you get a certificate of deposit which is basically a bond saying you'll get your money, your principal, back on a certain date, and you'll get interest at various intervals up until then. If you borrow money and sign a promissory note, you promise to repay and to pay interest. A mortgage is just a promissory note wrapped up with land and a house as collateral. A treasury note is just a bond issued by the federal government. Corporate bonds are just bonds issued by corporations.

You'll notice that most of finance is about money now and money later, so it's mainly about how money travels through time.

Also, there are a lot of names for the same thing. The distinctions are usually historical. On the sidewalk it might be an IOU; 20 floors up it's a bond; if there's real estate as collateral, it's a mortgage. (The real in real estate comes from the same root as royal, not realize.)

2) Operation Twist is based on the segmentation of the market for treasury notes and the fact that the US government cannot go broke.

Despite what the deficit scare mongerers say, the US government cannot go broke. It can always print more money. This means that federal debt is the safest game in town. (Look at what happened when one of the rating agencies cut the US credit rating; interest rates went down making it even easier to borrow.) Since interest rates are based on the level of risk of repayment, the treasury pays the lowest rates at every time scale. All other interest rates are based on these. A lender always has the choice to lend to the government or to some riskier party, but they expect higher interest payments as a premium for accepting the risk of losing their money.

The federal government borrows money at many different time scales, so one can buy government bonds with periods ranging from 30 days to 30 years. The short term notes, for a year or shorter, are mainly used for parking big lots of money safely. Large bank accounts are not FDIC insured, so if you have a million dollars you might need at any time, you'd constantly be buying and selling, 30 or 90 day notes. If you are a pension fund and are trying to meet your 2040 obligations, you might buy 20 or 30 year bonds. Most business lending is in the 10 year range so the interest rates on business loans are roughly tied to the 10 year government rate.

The goal of Operation Twist, also called quantitative easing, is to lower the 10 year government rate by manipulating the market for government bonds. The idea is that the Federal Reserve owns trillions of dollars of treasury bonds, more than anybody else, so they are big enough to influence rates across the board. Operation Twist has the Federal Reserve selling their 10 year bonds and buying 30 year bonds. This should lower the rates on 10 year notes and raise them on 30 year notes. Lower rates on 10 year treasury bonds should mean lower rates for loans across the board. Lower rates should stimulate the economy.

This would usually be the case, except that interest rates are already very low, and the economy has lots of other problems. If you account for inflation, federal interest rates are negative, meaning that the lender is paying the government to hold his or her money. It isn't clear they can go a lot lower or that this would have much effect. Also, businesses consider other factors when deciding whether to borrow money or not, for example, many of them are worried about their customers, and their customers are worried about their jobs and the size of their paychecks. It doesn't make sense to expand if no one is buying now.

03/09/12 - Volvelleteer Updates

We've done a few updates to our volvelle making program Volvelleteer. We've fixed a few bugs and cleaned up the interactions. It also works better with more modern Windows systems. Volvelles are those pairs of rotating cardboard disks, one with little windows in it that show a variety of information as you turn the back disk. Volvelleteer is a tool for making these given a table of text or numbers. If you are curious, check out Volvelleteer or check out our Kaleberg software page to see what other goodies we have lying around.

01/23/12 - Some Chemistry Software

We've updated our ancient Period Table of the Elements - five downloads since 2006 - to include a simple chemical equation solver and balancer. If you know what this means, then this post is for you. If you actually might need such a thing, then this post is probably a godsend. So, assuming you are one in a billion, follow the link and take a look at the latest update from Kaleberg Labs.

11/01/11 - Halloween

We had our usual Halloween passing out bales of candy to perhaps 200 tricker treaters. Our street must have a reputation as a soft touch. A reputation like that takes some living up to. That, and a lot of little candy bars. It also takes a giant spider in a giant web, our shaman transforming, and a bit of mad science. (Is there any other kind?)

05/24/11 - Constructomatic

We've been doing some geometry tutoring, and one thing seems to have led to another so we threw together a little program for doing geometry constructions. You put them together from points, lines and circles, and then you can interact with them. If it sounds intriguing, give it a try.

12/28/10 - Antisolar Crepuscular Light

One of the things about the Olympic Discovery Trail west of Morse Creek is the amazing view of the Strait of San Juan de Fuca. It is about 30 miles to Vancouver Island and farther to the San Juan Islands. The Cascades and Mount Baker are even farther, so there is a lot of sea and sky visible. Looking north, away from the sun, one often sees patterns in the shadows of clouds falling on other clouds. This is known as crepuscular light, and it can often be subtle, but sometimes the rays of light are impossible to miss. Just in case you are having trouble seeing them in the picture to the right, roll your cursor over it to see a contrast enhanced version.

04/23/10 - Shadow Mountain Telephone Booth

The telephone system seems to enter a time warp out near Lake Crescent. It's easy not to notice, but if you look carefully at one of the many telephone cable warning markers along East Beach Road, you'll see that they have good, old fashioned Bell System logos. There's none of that Qwisp, or Quaker, or Qwest stuff they put on our phone bills these days. The Bell System was a telephone system. Qwest was a breakfast cereal.

There are even a few markers, and some curious equipment, right along the Spruce Railroad Trail. You probably haven't noticed it because there is awful a lot of distracting beautiful scenery. Still, it is time warp country. Check out this telephone booth at Shadow Mountain. That's the store along route 101 that sells gasoline, hot dogs, books of ghost stories, and just about everything else. We suppose that Sasquatch uses it when he comes out of the woods and changes into his civvies. As we said, it's time warp country.


They have just about everything else, so why not a phone booth?

03/14/10 - Sunrise at Lake Crescent

It was quite a sunrise Saturday morning looking east over Lake Crescent, at least according to these images from the park service webcam. That's the moon rising along with the sun. Obviously, the sun couldn't have been that bright a the time, or the moon wouldn't be visible. It's definitely worth checking in on the various webcams now and then.

02/21/10 - Sparkling Light at Lake Crescent

It has been sunny and calm lately, so we noticed an amazing light out on Lake Crescent. We were on the Spruce Railroad Trail, and the light reflected from the gentle ripples on the lake reflected onto the trees, sparklling and twinkling. Our camera only captured this so well.

02/20/10 - From the Journal of the American Association for the Advancement of Science

I'm not sure how much of this is science and how much of this is stunt, but it was written up in the journal Science. Some guy named Felix Baumgartner is planning to jump from a helium balloon from about 20 miles up. Apparently, it's pretty tricky since it's minus 100 degrees up there and the air pressure is so low that water boils even when it is that cold. Still, it sounds like it could be real science.

The accompanying picture, though, was the clincher. If you look carefully, or click for a bigger version, you can see the SR-71 spy plane at cruising altitude, and way above that is Joe Kittinger, the current high altitude balloon jumping record holder. That's probably Felix's balloon up there at the top along with an action shot of Felix on his way down.


There's Joe!

02/18/10 - What's the next town after Joyce?

We were looking at an old map of Washington State in an early 1930s edition of The Volume Library and couldn't help noticing that there seemed to be a lot more towns west of Port Angeles back then. For example, there was the town of Ramapo, right there on the statewide map. What was Ramapo? Where is it today? There were even towns west of Joyce; the next town was Hilda, and even further west, there was the town of Majestic. How could we not have heard of a town named Majestic? We had driven out west on route 112, but we had never noticed any signs for Majestic.

Naturally, we decided to investigate. So, follow the link for the mystery of the missing towns, or who's Hilda.

02/11/10 - Sunrise, Sunset

This isn't a software site, but Kaleberg Laboratories does maintain a few little pieces of software. There's our equation solver, Equato, a computer teaching tool, Cardiac, a program for making volvelles, and a number of tide forecasting and tide finding tools. One surprisingly popular program is Sunrise Sunset which simply produces an iCal calendar giving the times of sunrise and sunset. It is just an old basic program rewritten. You type in your latitude and longitude, your time zone and a few other particulars and out scoots an iCal calendar ready to use. Apparently, a fair number of people have some concern with when the sun rises and sets. Now and then we get feedback about the program, usually noting that it is broken. The latest note was from an Australian who reminded us that they do daylight savings time a bit differently in the southern hemisphere, so we've added a Down Under option to account for winter and summer being reversed. It still doesn't support British double war time, but the updated version is now more useful for people on the other half of the planet.

If you have a Mac, you can download the program here.

01/01/10 - Blue Moon

This full moon we photographed on New Year's Eve is either a blue moon or the full moon after a blue moon. We aren't going to get into that argument. Instead, we are going to goggle in awe at the wonders of hand held photography. That's a pretty spectacular moon.

11/14/09 - From The Annals of Film Editing

From an article on the usefulness of subtitles in learning accents in foreign languages published by the journal Science:
"For the study, Dutch students who were fluent in English watched either a 25-minute episode of the Australian sitcom Kath & Kim, whose characters speak in broad accents from the Melbourne suburbs, or a version of Trainspotting, which was edited down to the same length by taking out the offensive parts."

According to the IMDB, Trainspotting has a 94 minute running time, so they cut out 69 minutes. That's pretty impressive.
