The Explainer General
She was 15 pounds below minimum weight for the Navy when she joined, but she had a mighty mind. Admiral Grace Hopper changed the Navy. And your world.
She graduated from Vassar College in math and physics then took a doctorate from Yale in math. She joined the Navy in World War II because it needed mathematicians to build the massive machines that computed tables of distance, gun elevation, projectile weight, windage and other factors for precise naval gunnery. Almost immediately she saw something other mathematicians didn’t see: computers could talk.
They weren’t just number crunchers to Grace. They could do much, much more if they were given a simple language that would bring the advantages of gigantic computing power and enormous data storage to common uses.
While working on the early computers she developed a “compiler,” a kind of translating machine that turned plain-language needs into a set of mathematical commands that retrieved number data from storage banks, performed thousands or millions of math operations, and provided real-world answers.
In 1959 she was crucial in devising the first broad-based computer language, COBOL (COmmon Business Oriented Language). It is the root of the many computer operating systems we use today.
Then-Captain Grace worked with the National Bureau of Standards to develop self-testing capabilities so a computer could “de-bug” itself. She coined this word when she extracted a fried moth disrupting one of her computers.
She led the Navy away from a few giant computers to interconnected, smaller, scattered computers, opening the door to the internet. You are reading plain language words from my small computer on your web-connected small computer. Thank you, Grace.
In 1985, at 79, she was promoted to rear admiral of the United States Navy Reserve. She said, “The most important thing I've accomplished, other than building the compiler, is training young people. They come to me, you know, and say, 'Do you think we can do this?' I say, ‘Try it.’ And I back 'em up. They need that. I keep track of them as they get older and I stir 'em up at intervals so they don't forget to take chances.” She died in 1992 at 85.
Admiral Grace Hopper received many awards and decorations but the Navy’s most sincere tribute came in 1996 when it named the guided missile cruiser DDG-70, USS Hopper. Naturally, its sailors call their ship “Amazing Grace.”
Jan Adkins successfully tackles the art and science of 10,000 years of bridge building and imparts a lot of historical drama along the way. The process is given fascinating life in this accessible study, wonderfully illustrated by Jan Adkins himself. Ranging from ancient Rome to the present day, from simple log bridges to marvels of industrial technology, and from well-known landmarks to little-known feats of engineering and art, this book gives readers a new appreciation for that most familiar of structures, the bridge.
Jan Adkins is a member of iNK's Authors on Call and is available for classroom programs through Field Trip Zoom, a terrific technology that requires only a computer, wifi, and a webcam. Click here to find out more.

A celebrity has just arrived in Mr. Madison’s classroom at El Verano Elementary School and the 3rd graders are beside themselves. “Here he is!” they exclaim as the visitor walks through the door.
This special guest has not come to give a lesson or tell a story. He is neither a star athlete nor a movie star. He doesn’t play an instrument, sing, dance or do magic tricks. His tricks are mostly limited to sit, stay and shake. He is a dog. His name is Fenway Bark.
An eight-year old chocolate-colored Labrador retriever, Fenway has been coming to El Verano for six years with his owner, Mara Kahn. He has helped hundreds of children become better readers. Fenway is a literacy dog.
“Fenway’s job is to listen while you’re reading,” explains Mara to the class, which is gathered in a circle around her and Fenway.
One of the best ways for children to improve their reading is to read aloud, but reading in front of an audience can be scary. What if Chelsea mispronounces a word? Or if Alex loses track of where he is on the page? Will everyone laugh? The fear can discourage some children from reading aloud at all.
Solution: read to a totally non-judgmental audience that doesn’t care what you read or how you read it. Read to a dog! When reading to dogs, young readers don’t have to worry about saying “whoof” when they meant to say “which.” With less anxiety and more confidence, young readers increase their reading fluency. That’s why literacy dogs visit hundreds of schools and libraries as reading buddies for children.
Vanessa sits cross-legged on the rug in Mr. Madison’s classroom. She gingerly opens Strega Nona by Tomie De Paola. Softly, slowly, she reads about Big Anthony who ignores Strega Nona’s instructions not to touch her magical pasta pot. Fenway sits up and looks at Vanessa. He gazes at the floor. Vanessa keeps reading. The pasta starts flowing. Fenway stretches out. Vanessa reads a little louder, a little faster. Pasta floods the town. Fenway licks Vanessa’s knee. She giggles and goes back to her book.
Today, six children got to read to the canine visitor. “It’s so cool to read to a dog,” said one boy who will get his chance next week. He was already thinking about choosing a doggone good book

See note at end. This is now history. Babies born around this time are now adults.
A cowardly bully came out
of his cave today to
trespass on our shining city.
Out of the blue
he had the nerve
to punch out its
two front teeth.
The pain is excruciating;
Bleeding is everywhere.
The remaining stumps are
We've lost our pretty smile.
We can't bite a big apple.
It's hard to look at mutilation.
Dazed, we check for damage.
Although choking on thick air,
we are very much alive.
Our heartbeat is strong.
There is no drop in our vital signs.
Blood rushes in to replace
Slowly we discover
we can still chew
and make a fist and
Oh yes, we'll make sure
this "holy" terror
can never return
to our playground
or our friends.'
How do we shadow box
a villain who doesn't
play by the rules?
We see evidence
of our noble,
and loving spirit.
Yet hate destroys
within as well as without.
Here then is our challenge:
We must keep this wound
becoming toxic to ourselves.
We must imagine the unimaginable
to thwart evil
before it comes back for more.
We must seek justice,
not vengeance to
preserve our soul.
We must trust our leaders
who see more
than this one tormenter.
We must be brave
As good as we believe
ourselves to be,
we must become better.
Scar tissue is stronger

Reflection: I wrote this poem on September 12, 2001. I am a New Yorker. One grandson, who was 4, was starting school, a few blocks from ground zero. My husband was working in the city. It was a terrible day. I wrote this poem to try and make sense of it for my readers. Do you think it is still true today?
Here I am in 2014 on the 43rd floor terrace in lower Manhattan. The brand-new Freedom Tower, on the site of the Twin Towers lost on 9/11, soars behind me. It is 1776 feet tall.

The Running Encyclopedia
The Renaissance began in Europe in the 15th century and marked the change from the medieval period to the modern world. Towering figures such as Michelangelo, Galileo, and especially Leonardo da Vinci were known as Renaissance men because of their talents and lasting achievements in several important areas of knowledge. They were also accomplished musicians, public speakers, athletes, poets, and so forth. And they were expected to do all this stuff without breaking a sweat.
You could give the same title to an ancient Egyptian named Imhotep, who lived about 2600 BCE. He was the vizier, the most important government official, during the reign of Pharaoh Djoser. He served as the high priest of the god Ra and was an expert astronomer.
Imhotep designed and oversaw the building of the first major pyramid in Egypt. Located at Saqqara, at the time it was the world’s tallest structure. He innovated the use of stones rather than mud bricks to build it, and it was that added strength that enabled the pyramid to rise so high. He is also credited with the invention of several devices that facilitated the construction.
Many people believe that Imhotep, rather than the Greek Hippocrates who lived more than 2,000 years later, is the real “Father of Medicine.” In an era when most physicians relied on magic spells and appeals to the gods, Imhotep prescribed dozens of effective down-to-earth treatments for illnesses and injuries.
He is credited with ending a seven-year famine in Egypt. He advised the pharaoh to make sacrifices to Khnum, the god of the annual flooding of the Nile River, and thereby provide desperately needed water to farmers. On a more practical level, he invented an improved irrigation system to carry water to the crops even if the river level was abnormally low.
In addition to these accomplishments, an inscription at the base of one of his statues notes that he was “Chief Carpenter, Chief Sculptor, and Maker of Vases in Chief.” In his little spare time, he wrote poetry and dispensed philosophical advice.
Imhotep can also boast of two accomplishments that eluded even Leonardo da Vinci. He was deified after his death and worshipped for many centuries, an honor accorded to hardly anyone besides the pharaohs. And today the comic book community gives him the credit for founding S.H.I.E.L.D., the Marvel Comics espionage and crime-fighting agency that became the basis for blockbuster movies such as Iron Man, Thor, and Captain America.
Jim Whiting has written a book on another great Egyptian leader -- Ramses the Great who lived about 1350 years after Imhotep. He fully lived up to the "Great" part of his name. His reign lasted for 67 years, the second longest in Egypt’s 3,000-year history. He had dozens of wives and more than 100 children, outliving many of them. He was a military leader who expanded the borders of his country. That resulted in decades of peace and prosperity for his people. He ordered huge statues of himself to be erected all over Egypt.
