Google's quantum computer chip, known as Bristlecone
Geek News

Nicole DiGiose, content editor of Electronic Products reports that "The race for mastering quantum computing is at its peak between major tech companies, and Google has plans to be the first to reach quantum supremacy with its latest design. The company’s quantum computer chip, known as Bristlecone, has the record-setting power of 72 quantum bits (qubits). Normal computers operate in binary and data is represented as zeros or ones, but in quantum mechanics, a qubit can represent both. This results in an exponential increase of power in quantum computing and allows quantum computers to perform different operations simultaneously. With Bristlecone, its qubits are arranged in a square array and get their quantum nature through superconductivity, allowing them to represent multiple states by conducting current in two different directions at once.

What the Great Lakes Geek is reading
Geek Book

The Great Lakes Geek just finished reading (listening to actually) Make Your Bed - Little things that can change your life by Admiral William H. McRaven (US Navy Retired)

On May 17, 2014, Admiral William H. McRaven addressed the graduating class of the University of Texas at Austin on their Commencement day. Taking inspiration from the university's slogan, "What starts here changes the world," he shared the ten principles he learned during Navy Seal training that helped him overcome challenges not only in his training and long Naval career, but also throughout his life; and he explained how anyone can use these basic lessons to change themselves-and the world-for the better.

Lotto Math
Geek Math

The last post about the probability of tossing a coin and getting 10 heads in a row prompted a question about the lottery. The conversation between Leonard's mother Beverly and Sheldon on the Big Bang Theory comes to mind:

Beverly: Is that a rhetorical point, or would you like to do the math?

Sheldon Cooper: I'd like to do the math.

Beverly: I'd like that, too.

Here we go. Say there are 44 possible numbers and you have to pick the lucky 6 to win. How many ways are there of choosing a 6-number combo from the 44?

The formula is C (44,6) which is 44 factorial divided by (6 factorial x 38 factorial) or 44! / (6! *38!). Then the probability of coming up with a specific 6 number combination is 1 over that number.

Refresher: Factorial is the product of that number and all the positive integers less than it. So, 6 factorial, designated as 6! is the product of 6x5x4x3x2x1 or 720. Factorial get huge fast. For example, 10! is 3,628,800. So 44! is huge and 1/44! is minute.

To see the chances for a particular lucky number being in the selected 6, you want to find the probability that the winning 6 number combination will contain any given number. First, you want to figure out how to not pick that number.

You have to choose the 6 numbers from the other 43 so use the formula C(43, 6). There are C(44,6) - C(43,6) combinations which include your lucky number.

The probability is then that result divided by C(44,6).

Moral? Don't quit your job to win the lottery.

Bob and Dan's Adventure to the PC Graveyard
Geek Blast from the Past

Computer techies (OK, geeks) Bob Coppedge and Dan Hanson used to take groups to various places of interest to computer professionals (OK, other geeks). They called it Bob and Dan's Excellent Adventures.

This video from 2004 was just unearthed from some old DVDs. This was a different adventure as Bob and Dan visited a cemetery and visited the graves of some old technology - from dBase to Win 95 before facing their own demise.

RIP John Perry Barlow
Geek News

John Perry Barlow was a founder of the Electronic Frontier Foundation and a strong believer in cyber liberties, He co-founded the EFF in 1990 with John Gilmore and Mitch Kapor to promote Internet civil liberties and to champion free expression and privacy online.

He passed away Wednesday at the age of 70.

Barlow was also a lyricist for the Grateful Dead and co-wrote songs with the Dead's Bob Weir such as Mexicali Blues and Cassidy.

I got to meet Barlow at Comdex in Las Vegas in 2002 when he was a panelist debating Internet civil liberties.

These lyrics from Barlow's Mexicali Blues seem fitting today:

Is there anything a man don't stand to lose
When the devil wants to take it all away
Cherish well your thoughts, keep a tight grip on your booze
'Cause thinking and drinking are all I have today

Flip a Coin
Geek Probability

The Great Lakes Geek often gets questions about gambling and the lottery. Just the other day I was asked to figure the odds of a tossed coin landing on 'heads' after 9 'heads' were tossed in a row.

I explained and the person still does not believe the answer. I told him that if a fair coin is tossed and heads comes up 9 times in a row it has no effect on the next toss. A coin has no memory so there is still the usual 50-50 chance of tails or heads. The previous 9 or 900 tosses have nothing to do with that next toss.

The confusion is about the probability of tossing 10 'heads' in a row. That's a whole 'nother smoke.

The probability of one head in a row is 1 out of 2 (.5), the probability of 2 heads in a row is 1 out of 4 (.5 x .5), 3 heads is 1 out of 8 (.5 x .5 x .5) and so on. So the probability of 10 heads in a row is 1 out of 1024 (.5 to the 10th power) or .0009765625.

In a real world case where someone tosses 9 heads in a row I would be concerned about the fairness of the coin.

Foreign Language Learning Trends
Geek Education

The Confucius Institute at Cleveland State University hosted their 10th annual Teacher Appreciation Day on the campus of CSU. About 270 teachers, students and administrators from 26 different schools and organizations attended. See photos and videos from the Teacher's Appreciation Day event

I am a huge proponent of language studies for business, culture and even security reasons. So, one of the most interesting parts of the event to me was from the presentation by Ryan T. Wertz, World Languages Consultant, Ohio Department of Education. He discussed Teaching and Learning Chinese in the state of Ohio.

The total languages taught in K-12 in Ohio has remained pretty consistent from 2004-2016. It averages about 13 different languages.

In the 2005-2006 school year 19.8% of 1.8 million K-12 students in Ohio took a language. This has gone up somewhat in the 2015-16 year with 19.2% of 1.76 million K-12 students studying a language. That's 359,390 in 2005 and 345,888 in 2015. Pretty close.

The enrollment for which languages studied is what has changed the most.

Languages ranked by enrollemt 2005

In 2005, Spanish, French and German were the Big 3 with Exploratory (not really a language - just looking at cultures - Boo! Hiss!) coming in 4th followed by Latin, American Sign Language and then a big drop to the bottom group which includes Japanese, Arabic, Russian and Chinese. Chinese came in at #11.

Languages ranked by enrollemt 2015


In 2015, Spanish and French remained 1 and 2 but Exploratory usurped 3rd place from German. While languages such as Japanese, Arabic and Russian still trailed the pack there was a large jump for Chinese. Chinese language enrollment went from #11 to #5 and from less than 500 to over 10,000 students.

Can anyone argue against the value of being multilingual in our modern world? Businesses and the Government need fluent speakers - especially in some of the languages that are not taught as much such as Arabic and Russian. Yes, Spanish and French are useful and should be studied. They are considered a Type 1 (easiest) language to learn. Mandarin Chinese, on the other hand, is a Type 4 in difficulty, the hardest level.

It's encouraging to see the increase in Chinese learners in K-12 but we still have a long way to go. And we need a boost to Arabic, Russian and other under taught languages too.

The earlier the better. As someone struggling to pick up Mandarin and some other languages, I can confirm that it's a lot easier to learn with daily immersion in gradeschool than as an adult trying to fit some time in each day. My recently reinvigorated French skills cry out "Allons y" (Let's go!)

Flying Squirrel photobomb leads to new discovery
Geek News

A photobombing squirrel helped a Northland College student document the highest recorded observation of the gray tree frog in northern Wisconsin.

As part of a larger study of old and large white pine canopies, Northland College senior Madison Laughlin of Edmonds, Washington, documented the tree frog almost 70 feet above the ground - more than double the highest previously on record. Her findings were published in the May issue of the scientific journal, Ecology.

"This frog appears to be able to weather sun during the day in the canopy by finding shady and cool spots,"¯said Laughlin, who studies natural resources and geology.

As part of the study, Laughlin and her tree-climbing professors set up three motion sensitive cameras in three white pines to observe life at the tops of the trees. They have already identified 17 species of animals - squirrels, birds, mice, and tree frogs - as well as a mushroom species, a variety of insects and many lichen species particular to this special habitat.

Madison Laughlin

"This is research that is literally being done in our backyard," said Assistant Professor of Natural Resources Erik Olson. "That is one of the beautiful things about science - we don't have to go to the ends of the Earth to make new insights into our world."

In this case, capturing frogs in unexpected places. Tree frogs are small and similar in temperature to their environment so do not set off the motion sensitive cameras. However, flying squirrels do. And on four different occasions, flying squirrels have exposed tree frogs up high.

"It was really exciting to find something that wasn't a squirrel," Laughlin said of looking through hundreds of collected camera captures.

Laughlin says that there is a gap in what we know about tree frogs. "Oddly, there isn't much research on tree frogs in trees. Most of the research is about their breeding, which takes place in ponds," she said. "This research is helping open the door to the vertical dimension of habitat."

Treefrog and squirrel

These images suggest a higher level of habitat usage in the tops of trees than previously thought. "I love forestry and forest ecology,"¯Laughlin said. "And I've never thought about the three-dimensional aspect of habitat - there's a lot going on up there."

Additional work is underway to describe the habitat usage of other animals high in the trees and to begin to answer the question of why tree frogs go so high.

"We're not surprised that the canopy is an important habitat, but we are surprised how many and what species are up there and how often they visit," said Assistant Professor of Forestry Jonathan Martin who is co-directing the research. "The combination of the scale and growth patterns of these trees as well as the habitat surprises gives me a renewed appreciation for the complex processes occurring high off ground."

Feynman Lectures on Physics
Geek Link

The famous Feynman Lectures on Physics is a physics textbook based on some lectures by Richard P. Feynman, a Nobel laureate who has sometimes been called "The Great Explainer". The lectures were given to undergraduate students at the California Institute of Technology (Caltech), during 1961–1963 and have been a favorite for aspiring physicists ever since.

The three volumes of the book focus on mechanics, radiation, and heat, including relativistic effects (Vol 1), electromagnetism and matter (Vol 2) and quantum mechanics (Vol 3).

In case you didn't know (or forgot) in 2013, Caltech in cooperation with The Feynman Lectures Website made the book freely available, on the web.

As the site says, "Now, anyone with internet access and a web browser can enjoy reading a high quality up-to-date copy of Feynman's legendary lectures. This edition has been designed for ease of reading on devices of any size or shape; text, figures and equations can all be zoomed without degradation.

This experiment proved the non-existence of the luminiferous ether and was later cited as circumstantial evidence in support of special relativity as proposed by Albert Einstein in 1905.

Michelson was professor of physics at the Case School of Applied Science, and Morley was professor of chemistry at Western Reserve University (WRU), which shared a campus with the Case School on the eastern edge of Cleveland. The Michelson-Morley Experiment was performed in several periods of concentrated observations between April and July 1887, in the basement of Adelbert Dormitory of WRU (later renamed Pierce Hall, demolished in 1962).

Michelson became the first American to win a Nobel Prize in science.

Calvin & Hobbes
Geek Classic Humor

Now available for the first time as an e-book! The cartoons in this e-book have been specially formatted for optimal viewing. The e-book will only work on color tablets and is not intended for viewing on desktop apps or black and white tablets.



Perhaps the most brilliant comic strip ever created, Calvin and Hobbes continues to entertain with dazzling cartooning and tremendous humor.

Bill Watterson's Calvin and Hobbes has been a worldwide favorite since its introduction in 1985. The strip follows the richly imaginative adventures of Calvin and his trusty tiger, Hobbes. Whether a poignant look at serious family issues or a round of time-travel (with the aid of a well-labeled cardboard box), Calvin and Hobbes will astound and delight you.

Beginning with the day Hobbes sprang into Calvin's tuna fish trap, the first two Calvin and Hobbes collections, Calvin and Hobbes and Something Under The Bed Is Drooling, are brought together in this treasury. Including black-and-white dailies and color Sundays, The Essential Calvin and Hobbes also features an original full-color 16-page story.

Write your own OS
Geek Software

The Great Lakes Geek thinks that programmers of his generation (harrumph!) are better because they didn't have all the visual tools. In fact the best learning experience, in his not so humble opinion, is writing directly to the processor, without an operating system.

A great learning tool is writing you own OS in assembler. There is a free online course from the Cambridge Computer Laboratory that teaches you how to write your own operating system using assembly code.

Give it a try you young whippersnappers

Q: Why did the Higgs Boson go to church?
A: For the mass.

Did you hear about the company that sells elastomeric insulators?
Their motto is "Resistance is butyl".

Intern: How I get to the marketing department?
Engineer: Easy, go west until you can smell it and then turn north until you step in it.

We had our engineers work in HR for a week to encourage better teamwork. They immediately sent out an employment ad that read "Supermodels wanted, (must be able to solder.)"
