100-Year-Old Wedding Night Advice for Newlyweds

Imagine yourself as a young person during an era when there was no sex ed in high school. Sure, pornography exists, but you're more likely to get your hands on the smallpox virus than a properly illicit "French Postcard." The only depictions of sexuality you'll regularly encounter in your young life are the disturbing interactions of farm animals. And yet your wedding night approaches. How do you prepare yourself?

Well, you'll read any number of delicately worded advice books, written by people of apparent high moral standing and (usually vague) medical credentials. Here's a sampling.

What a girl should know

First, the most important thing, as imparted to us by Emma Frances Angell Drake in 1902's What a Young Wife Ought to Know: "From the wedding day, the young matron should shape her life to the probable and desired contingency of conception and maternity. Otherwise she has no right or title to wifehood."

Now that your purpose as a woman has been made clear, how do you achieve it? It was assumed that all men approaching marriage had a rudimentary understanding of what was going to happen. But women of quality would not have been so exposed to rude talk, rumors, and basic knowledge of their own body. She might not even know the names and function of her own reproductive organs. This ignorance, says Walter Gallichan in 1918's The Psychology of Marriage, can be fatal:

It is necessary that the virgin should not enter the married state without even theoretical knowledge of sex. Those who counsel such unenlightenment are unconsciously guilty of cruelty. Many young wives have considered themselves the subjects of outrage on the bridal night. There have been cases of sudden disappearance and flight on the eve of wedding. Now and then one reads a painful report of suicide at this crisis in a girl's life. [The Psychology of Marriage]

But how much should a girl know to keep her from running screaming into the night or driving her to suicide? It depends on which expert you ask, but according to Maurice Bigelow in 1916's Sex-education: A Series of Lectures Concerning Knowledge of Sex in Its Relation to Human Life, not so much as to make her too curious:

She should know the scientific names of her organs, not because there are many vulgar names as in the case of boys, but because dignified names help attitude. Ovaries, uterus (womb), vagina, Fallopian tubes, and vulva will be sufficient. Detailed description of the external organs (vulva) might arouse curiosity that leads to exploration and irritation. [Sex-education: A Series of Lectures Concerning Knowledge of Sex in Its Relation to Human Life]

Bigelow asserts that a girl should only be taught that she has a vulva, not the parts that make up a vulva, lest she want to see or touch those parts of herself. Curiosity can lead to exploration, which can lead to…irritation.

Also, knowing too much is unbecoming in a bride. Men adore the fact you're ashamed of yourself, as Karl Heinzen explains in 1891'sThe Rights of Women and Their Sexual Relations:

There is, indeed, another kind of shame. It is that delicate shyness which the virgin feels when she is to step beyond the boundary of virginity, as well as that feminine reserve which strives to hide or to guard her charms. This "shame" is…a natural consequence of an emotional affection upon entering a new life…it has nothing to do with the consciousness or the fear of seeing something improper disclosed, is an ornament to every woman, and its absence is a proof of dullness and coarseness. [The Rights of Women and Their Sexual Relations]

It's so adorable that you feel icky and confused, darling.

Make sure he knows you're going to want to maintain your human rights beforehand.

Bernarr Macfadden was not afraid to take on the controversial new idea that women have rights over their own bodies in his 1918 Womanhood and Marriage. He's willing to allow that women might be embracing this new fad. But it is of greatest importance that she tells her husband she feels this way before a wedding date is set:

With the development of the idea of personal freedom has come the feeling, on the part of many women, that they should have the right of ownership of their own bodies — in other words, that they should have the privilege of choosing whether or not they will acquiesce in their husband's desire for entering into the physical relationship of marriage. Since, however, it has been for so long a time an accepted idea that the husband's right over the wife's body was inherent, it is advisable for any young woman who takes the other point of view to make her attitude thoroughly understood by her future husband before she definitely takes upon herself the obligations of the marriage state. [Womanhood and Marriage]

The fact that a cow is a temperamental milker is not the sort of thing you spring on a poor guy after he's already bought her. Full disclosure makes for good business.

The consummation

Before the actual consummation occurs, a few things should be considered. First, there is the physical condition of virginity. Nearly all 19th-century marital advice shuns the Biblical idea of blood proof of virginity. One Dr. Napheys says to know if your wife is truly a virgin, pay attention to her outer purity, not her inner membranes:

The presence or absence of the hymen is no test. There is, in fact, no sign whatever which allows even an expert positively to say that a woman has or has not suffered the approaches of one of the opposite sex. The one true and only test which any man should look for is modesty in demeanor before marriage, absence of both assumed ignorance and a disagreeable familiarity, and a pure and religious frame of mind. When these are present, he need not doubt that he has a faithful and chaste wife.

But if such a membrane is present, tender care should be taken. William Josephus Robinson, author of 1920's Sex Knowledge for Men, says that a truly loving husband will proceed with the deflowering of his wife very slowly, sometimes taking up to a week of gentle introductions before a full connection is made.

Sylvanus Stall, who writes in 1899's What a Young Husband Ought to Know, is not as generous in his timeline, but insists that if a wife is still hurting weeks after the wedding night, she should probably see a doctor:

It is important for young husbands to know that when a serious inconvenience is experienced in the consummation of marriage, if the hymen is not easily removed by care and consideration, but remains an impediment or a pain for a period of days, or a couple of weeks, medical advice and assistance should by all means be sought. [What a Young Husband Ought to Know]

Don't be in such a hurry to consummate, anyway. That fruit is going to taste pretty bland once it's no longer forbidden, according to Mrs. E.B. Duffey in her book The Relations of the Sexes: "Do not be in too great haste to brush the bloom from the fruit you covet. It will lose half its attractions at once."

No sex or bad sex makes women crazy

Robinson gets straight to the point when he says, "The bridal night is the most important turning point in a woman's entire life." Not just because this night will determine the success of the entire marriage (more on that later), but because, according to Gallichan, married sex is the only way a woman can keep her health. It's the only way to channel her anabolic energy:

Every intelligent physician knows that conjugal life is the salvation of many women. Every specialist in the nervous and psychic disorders of women is aware that a healthy vita sexualis is the remedy for many troubles of the brain. Many women have conflicts and longings which they attribute to any other source than enforced single life, disharmonious marriage, or unfulfilled maternal processes. The anabolic energy of woman may be said to desire avidly the catabolic force of man as the completion of being. No argument, no evasion, can destroy this fact of human life. [Sex Knowledge for Men]

Any woman who does not enjoy her sex life is at risk for insanity and illness—an interesting proposition that might still find a good many female supporters today.

Husband or beast?

Now let us revisit the subject of a husband coveting the forbidden fruit of his bride's love bud. New husbands are often driven mad by their desire to obtain this treasure. But be warned, one night of binging can wreck an entire life, says Mrs. Duffey:

This bud of passion cannot be forced rudely open. Its development must be the work of time. If the young wife is met with violence, if she finds that her husband regards the gratification of his own desires more than her feelings — and if she be worn and wearied with excesses in the early days of her married life, the bud will be blighted. The husband will have only himself to blame if he is bound all his life to an apathetic, irresponsive wife. It is easy to imagine the unsatisfactory conjugal relations which are brought about in punishment of the husband's early impetuosity and ignorance. He finds an unreciprocal wife, doubts her affection for him, because, with his masculine nature, he cannot conceive of a love unblended with passion. [The Relations of the Sexes]

Stall describes how an over-ambitious husband will ruin both his and his wife's life:

Many otherwise kind men have become possessed with the thought that every right is theirs immediately; and in their inconsiderate, rapacious passion, in the speedy consummation of marriage, at whatever cost of pain or wounded feeling on the part of her whom they have taken to love and honor, they well-nigh wreck the after happiness of both in the first days of their united lives. Husband beware of the wrong of committing a veritable outrage upon the person of her whom God has given you as your companion, and suffering ever after the stings of remorse, that she never again can feel the same respect and love for you that she could, had you been more considerate of her feelings and desires. It will be difficult for her to be persuaded that the animal nature does not control and dominate your love for her, rather than the higher instincts of the soul. [What a Young Husband Ought to Know]

For all your innocent bride knows, you made up this weird thing you want to do to her. A certain amount of patience will show her that you care more about her person than her privates. Forget this, and you have personally created a woman who will hate you the rest of her life.

But then again, if a woman does not enjoy sex, her husband will begin to hate her:

The woman who turns with aversion from a perfunctory performance of "conjugal duty" inspires an ardent and affectionate husband with the deepest suspicion of her love. His devotion must be strong indeed if he can preserve love and esteem for his wife after repeated suggestion of apathy, or manifestations of open repugnance or shameful compliance. [What a Young Husband Ought to Know]

The importance of restraint

Even if you are a gentle husband and lover, and even if your wife is enjoying herself, restraint is imperative. Says Robinson:

It will be seen that the husband who wishes to keep and retain the regard, affection, and gratitude of his wife, will be moderate and circumspect during the first few weeks of married life. Unless, of course, the wife herself is of a passionate nature and demands frequent satisfaction. In such cases the husband will comply with his wife's wishes as far as he can without injuring his health. [Sex Knowledge for Men]

Yes, the husband's health is at risk from over-indulgence. Even if a new wife is fond of the conjugal act, she must learn to restrain herself for her husband's sake, lest she drain him of his vital fluids. Macfadden explains:

Wives must understand that the life-giving fluid called the semen, which is produced in the creative organs of the man, is of great value in the upbuilding of his own body. It is only within comparatively recent times that the marvelous power of this creative fluid in building up and making over the body of the individual has been thoroughly understood. [Womanhood and Marriage]

Furthermore, it is of the utmost importance that if a couple is to have copious amounts of sex, that the woman be joyful and satisfied in the act. Otherwise, magnetic energy is not exchanged and you end up draining him like a sexual vampire:

In sexual intimacies, there is a discharge of this creative fluid from the body of the man, but where there is a full response on the part of the wife, there seems to be an exchange of magnetism or energy which makes up for the loss. If, however, his desire alone is active and she is simply fulfilling a supposed wifely duty, she gives nothing to him, and he, therefore, suffers a definite loss in vitality. It is claimed by some that such one-sided intimacies are almost as harmful to the man as masturbation. [Womanhood and Marriage]

As quaint as they seem to us, and as misinformed as they are, these books were trying to help. They were lights, however dim, in the fog of Victorian sexual confusion. They encouraged people to replace ignorance with education, selfishness with compassion. They didn't have the knowledge or values we have now, but the core ethic of trying to clear up rumor and confusion was still there, and is still admirable.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning
May 21, 2017

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!

8 Common Dog Behaviors, Decoded
May 25, 2017
Original image

Dogs are a lot more complicated than we give them credit for. As a result, sometimes things get lost in translation. We’ve yet to invent a dog-to-English translator, but there are certain behaviors you can learn to read in order to better understand what your dog is trying to tell you. The more tuned-in you are to your dog’s emotions, the better you’ll be able to respond—whether that means giving her some space or welcoming a wet, slobbery kiss. 

1. What you’ll see: Your dog is standing with his legs and body relaxed and tail low. His ears are up, but not pointed forward. His mouth is slightly open, he’s panting lightly, and his tongue is loose. His eyes? Soft or maybe slightly squinty from getting his smile on.

What it means: “Hey there, friend!” Your pup is in a calm, relaxed state. He’s open to mingling, which means you can feel comfortable letting friends say hi.

2. What you’ll see: Your dog is standing with her body leaning forward. Her ears are erect and angled forward—or have at least perked up if they’re floppy—and her mouth is closed. Her tail might be sticking out horizontally or sticking straight up and wagging slightly.

What it means: “Hark! Who goes there?!” Something caught your pup’s attention and now she’s on high alert, trying to discern whether or not the person, animal, or situation is a threat. She’ll likely stay on guard until she feels safe or becomes distracted.

3. What you’ll see: Your dog is standing, leaning slightly forward. His body and legs are tense, and his hackles—those hairs along his back and neck—are raised. His tail is stiff and twitching, not swooping playfully. His mouth is open, teeth are exposed, and he may be snarling, snapping, or barking excessively.

What it means: “Don’t mess with me!” This dog is asserting his social dominance and letting others know that he might attack if they don’t defer accordingly. A dog in this stance could be either offensively aggressive or defensively aggressive. If you encounter a dog in this state, play it safe and back away slowly without making eye contact.

4. What you’ll see: As another dog approaches, your dog lies down on his back with his tail tucked in between his legs. His paws are tucked in too, his ears are flat, and he isn’t making direct eye contact with the other dog standing over him.

What it means: “I come in peace!” Your pooch is displaying signs of submission to a more dominant dog, conveying total surrender to avoid physical confrontation. Other, less obvious, signs of submission include ears that are flattened back against the head, an avoidance of eye contact, a tongue flick, and bared teeth. Yup—a dog might bare his teeth while still being submissive, but they’ll likely be clenched together, the lips opened horizontally rather than curled up to show the front canines. A submissive dog will also slink backward or inward rather than forward, which would indicate more aggressive behavior.

5. What you’ll see: Your dog is crouching with her back hunched, tail tucked, and the corner of her mouth pulled back with lips slightly curled. Her shoulders, or hackles, are raised and her ears are flattened. She’s avoiding eye contact.

What it means: “I’m scared, but will fight you if I have to.” This dog’s fight or flight instincts have been activated. It’s best to keep your distance from a dog in this emotional state because she could attack if she feels cornered.

6. What you’ll see: You’re staring at your dog, holding eye contact. Your dog looks away from you, tentatively looks back, then looks away again. After some time, he licks his chops and yawns.

What it means: “I don’t know what’s going on and it’s weirding me out.” Your dog doesn’t know what to make of the situation, but rather than nipping or barking, he’ll stick to behaviors he knows are OK, like yawning, licking his chops, or shaking as if he’s wet. You’ll want to intervene by removing whatever it is causing him discomfort—such as an overly grabby child—and giving him some space to relax.

7. What you’ll see: Your dog has her front paws bent and lowered onto the ground with her rear in the air. Her body is relaxed, loose, and wiggly, and her tail is up and wagging from side to side. She might also let out a high-pitched or impatient bark.

What it means: “What’s the hold up? Let’s play!” This classic stance, known to dog trainers and behaviorists as “the play bow,” is a sign she’s ready to let the good times roll. Get ready for a round of fetch or tug of war, or for a good long outing at the dog park.

8. What you’ll see: You’ve just gotten home from work and your dog rushes over. He can’t stop wiggling his backside, and he may even lower himself into a giant stretch, like he’s doing yoga.

What it means: “OhmygoshImsohappytoseeyou I love you so much you’re my best friend foreverandeverandever!!!!” This one’s easy: Your pup is overjoyed his BFF is back. That big stretch is something dogs don’t pull out for just anyone; they save that for the people they truly love. Show him you feel the same way with a good belly rub and a handful of his favorite treats.

The best way to say “I love you” in dog? A monthly subscription to BarkBox. Your favorite pup will get a package filled with treats, toys, and other good stuff (and in return, you’ll probably get lots of sloppy kisses). Visit BarkBox to learn more.
