Charles Babbage And The Difference Engine

Charles Babbage

In the 1820s, Charles Babbage dreamed of eliminating deadly calculation errors that threatened sailors’ lives. His solution? The Difference Engine – a massive mechanical calculator designed to automate the creation of mathematical tables used in navigation.
Though Babbage’s original project was abandoned in 1842 due to funding issues, his detailed drawings survived. In 2002, engineers at London’s Science Museum achieved what Babbage couldn’t – they built his engine exactly to specification. The result was breathtaking: a 7-foot-tall brass and steel masterpiece containing 8,000 precision parts and weighing 5 tons.
When activated, this beautiful machine springs to life with hundreds of gears working in perfect harmony. It can calculate complex mathematical tables with flawless accuracy – proving that Babbage’s 19th-century design was sound all along.
The working Difference Engine stands today as a testament to Victorian ingenuity and the timeless pursuit of technological advancement. While it took nearly 200 years, Babbage’s mechanical marvel finally became reality.

The Worst Exercises People Still Do (And What’s Better)

Superman Bad

Further to my previous post…

The comments are as educational as the video. Here are some:

1. The purpose of the plank is for strengthening the inner spine muscles. To use them for building is ridiculous. To use them to strengthen inner muscles for the purpose of back recover is priceless.

2.Remember that this is body building advice. Planks are good for general core stability and back pain.

3. As a career trainer and rehab specialist (23 years) I train general population. There are many factors that go into program design. I wish all my clients could safely execute the most concentric/eccentric full range of motion exercises. Alas, their injury, mobility, rom, and other limitations require “less optimal” exercises.

Rock A Bye Baby

Rock A Bye Baby

Davy Crockett’s older sister, Effie Crockett was invited to help some mothers in the Muskogee Tribe. Once she arrived in camp, Effie laughed at what she saw. The Muskogee Tribe had a custom of cradling their papooses among the swaying branches of birch trees. This protected their babies from ground insects, the sun, and wild animals.

After first finding it funny, she soon learned all the great reasons for this practice and marveled at the beauty of it.

Effie watched the swaying and soothing motion of the topmost branches of the trees. She loved how each baby enjoyed nature, how they listened to the songbirds, observed every ladybug, and smiled at the colors of a butterfly, every little breeze was felt and enjoyed by these young ones; each babe seemd perfectly content.

One of the Tribal mothers began to sing a song to the children in her native tongue. As the Muskogee mother sang, Miss Effie observed a small tear running down the mother’s cheek.

Lulu se pepe i le pito i luga o le laau,
A agi le matagi e luluina le moega pepe,
A gau le lala e pa?u ai le moega pepe,
Ma o le a sau i lalo pepe, moega pepe ma mea uma.

Effie translated the words and kept the tune. She shared it with everyone and it soon became a wildly popular nursery rhyme among the Colonies.

The English translation:
Rock-a-bye baby on the tree top,
When the wind blows the cradle will rock,
When the bough breaks the cradle will fall,
And down will come baby, cradle and all.

Why did the Muskogee mother cry?

A “bough” is simply a tree branch, and its breaking was used by the Muskogee mothers as an analogy of their little baby growing up.

Their little baby would soon outgrow his cradle. With each gently rocking wind, time was passing. One day, little baby would no longer need the protection of his mother. One day, the “branch” would break because her little baby had become too heavy. The “cradle” would fall to the earth – the child, no longer a baby, would dust himself off and grow into a man.

The now famous lullaby was first printed in Mother Goose’s Melody in London in 1765.

The actual origin and meaning of the rhyme has been subjects of various theories and folklore, but none of them have been conclusively proven.
