15 Empowering Quotes From Elizabeth Cady Stanton

Elizabeth Cady Stanton was born on November 12, 1815 and dedicated her life to progressing the women’s rights movement in America. She organized, she rallied, advocated, protested, wrote, and, most importantly, spoke. Here are just a few of the activist’s most powerful words.

1. ON THE LIFE OF FRIEND SUSAN B. ANTHONY

"To live for a principle, for the triumph of some reform by which all mankind are to be lifted up—to be wedded to an idea—may be, after all, the holiest and happiest of marriages."

— From The Life and Work of Susan B. Anthony

2. ON HER HOPES FOR YOUNG WOMEN

“I would have girls regard themselves not as adjectives, but as nouns.”

— From an 1870 lecture called “Our Girls”

3. ON THE IMPORTANCE OF POLITICAL EQUALITY

“To throw obstacles in the way of a complete education is like putting out the eyes; to deny the rights of property is like cutting off the hands. To refuse political equality is to rob the ostracized of all self-respect, of credit in the market place, of recompense in the world of work, of a voice in choosing those who make and administer the law, a choice in the jury before whom they are tried, and in the judge who decides their punishment.”

— From “Solitude of Self

4. ON HOW THE DECLARATION OF INDEPENDENCE COULD USE AN EDIT

“We hold these truths to be self-evident: that all men and women are created equal.”

— From "The Declaration of Rights and Sentiments"

5. ON THE CHANGING TIMES

“Come, come, my conservative friend, wipe the dew off your spectacles, and see that the world is moving.”

— From The Woman’s Bible

6. ON TRUTH

“Truth is the only safe ground to stand upon.”

— From The Woman’s Bible

7. ON KEEPING BUSY.

“In a word, I am always busy, which is perhaps the chief reason why I am always well.”

— From Stanton’s diaries

8. ON INDEPENDENCE

"Whatever the theories may be of woman's dependence on man, in the supreme moments of her life, he cannot bear her burdens. In the tragedies and triumphs of human experience, each mortal stands alone."

— From “Solitude of Self

9. ON GETTING OLDER

“... the hey-day of woman's life is on the shady side of fifty, when the vital forces heretofore expended in other ways are garnered in the brain …”

— From Elizabeth Cady Stanton as revealed in her letters, diary and reminiscences

10. ON COURAGE

“The best protection any woman can have ... is courage.”

— From Elizabeth Cady Stanton and Susan B. Anthony: Fighting Together for Women's Rights

11. ON BETTERING ONESELF

“Put it down in capital letters: SELF-DEVELOPMENT IS A HIGHER DUTY THAN SELF-SACRIFICE. The thing that most retards and militates against women’s self development is self-sacrifice.”

— As told to a reporter, via In a Different Voice

12. ON THE BOSTON TEA PARTY

“It was just so in the American Revolution, in 1776, the first delicacy the men threw overboard in Boston harbor was the tea, woman's favorite beverage. The tobacco and whiskey, though heavily taxed, they clung to with the tenacity of the devil-fish.”

― From The Women’s Bible

13. ON HOW TO BECOME A BETTER PUBLIC SPEAKER

“Dress loose, take a great deal of exercise, and be particular about your diet and sleep sound enough, the body has a great effect on the mind.”

— As told to Susan B. Anthony

14. ON LIVING YOUR TRUTH

“The moment we begin to fear the opinions of others and hesitate to tell the truth that is in us, and from motives of policy are silent when we should speak, the divine floods of light and life no longer flow into our souls. Every truth we see is ours to give the world, not to keep for ourselves alone, for in so doing we cheat humanity out of their rights and check our own development.”

— From an 1890 speech to the National American Woman Suffrage Association

15. ON MOTHERHOOD

“We are, as a sex, infinitely superior to men, and if we were free and developed, healthy in body and mind, as we should be under natural conditions, our motherhood would be our glory. That function gives women such wisdom and power as no male can possess.”

— From Stanton’s letters

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!
