Pedantic math whizzes may insist that Pi Day should really be called Pi Approximation Day. The ratio of a circle's circumference to its diameter is commonly shortened to 3.14, but the sequence is actually infinite. Just in time for Pi Day on March 14 (3/14), a Google engineer has set a new record for the most pi digits ever calculated, Business Insider reports.

The previous record for the known digits of pi stood at 22.4 trillion digits. As Google announced on Pi Day 2019, Emma Haruka Iwao, a cloud developer advocate who's been with the company for three years, has added 9 million digits to that figure.

Working out of a lab in Osaka, Japan, she used Google's cloud-computing service to crunch 170 terabytes of data. For comparison, a single terabyte can hold 40 days worth of video. The process required 25 virtual machines running the y-cruncher program over four months.

According to Google, this marks the first time cloud computing has been used to calculate a record number of pi digits. Haruka Iwao has been working on cracking new pi sequences since she first downloaded software to calculate the number on her home computer at age 12. She's the third woman to break the pi record, and she's interested in discovering even more digits.

Anyone can download the full sequence onto their computer from Google. Memorizing all 31,415,926,535,897 digits may be impossible, but you can memorize at least the first 100 with this basic technique.

# 7 Ways Victorian Fashion Could Kill You

While getting dressed in the morning can seem like a hassle (pajamas are so much more comfortable), few of us worry about our clothes leading to our death. That wasn’t the case during the Victorian era, when fashionable fabrics and accessories sometimes came at great price for both makers and wearers. In Fashion Victims: The Dangers of Dress Past and Present, Alison Matthews David, a professor in the School of Fashion at Ryerson University in Toronto, outlines the many toxic, flammable, and otherwise highly hazardous components of high style during the 19th century. Here are a few of the worst offenders.

## 1. Poisonous Dyes

Before the 1780s, green was a tricky color to create on clothes, and dressmakers depended on a combination of yellow and blue dyes to produce the hue. But in the late 1770s a Swedish/German chemist named Carl Wilhelm Scheele invented a new green pigment by mixing potassium and white arsenic on a solution of copper vitriol. The pigment was dubbed Scheele’s Green, and later Paris Green, among other names, and it became a huge sensation, used to color walls, paintings, and fabrics as well as candles, candies, food wrappers, and even children’s toys. Not surprisingly, it also caused sores, scabs, and damaged tissue, as well as nausea, colic, diarrhea, and constant headaches.

Although fashionable women wore arsenic-dyed fabrics—even Queen Victoria was depicted in one—its health effects were worst among the textile and other workers who created the clothes and often labored in warm, arsenic-impregnated rooms day after day. (Some scholars have even theorized that Napoleon might have been poisoned by the arsenic-laced wallpaper hung in his St. Helena home.)

Arsenical dyes were also a popular addition to artificial flowers and leaves, which meant they were frequently pinned to clothes or fastened on heads. In the 1860s, a report commissioned by the Ladies’ Sanitary Association found that the average headdress contained enough arsenic to poison 20 people. The British Medical Journal wrote of the green-clad Victorian woman: “She actually carries in her skirts poison enough to slay the whole of the admirers she may meet with in half a dozen ball-rooms.” Despite repeated warnings in the press, and from doctors and scientists, the Victorians seemed in love with emerald green arsenic dyes; ironically, they acted like a reminder of the nature then swiftly being lost to industrialization, David says.

## 2. Pestilential Fabrics

Soldiers of the Victorian era (and earlier) were plagued by lice and other body parasites that carried deadly diseases such as typhus and trench fever. But soldiers weren’t the only victims of disease carried via fabric—even the wealthy sometimes wore clothing that was made or cleaned by the sick in sweatshops or tenements, and which spread disease as a result. According to David, the daughter of Victorian Prime Minister Sir Robert Peel died after her riding habit, given to her by her father as a gift, was finished in the house of a poor seamstress who had used it to cover her sick husband as he lay shivering with typhus-induced chills. Peel’s daughter contracted typhus after wearing the garment, and died on the eve of her wedding.

Women also worried about their skirts sweeping through the muck and excrement of city streets, where bacteria was rife, and some wore special skirt-fasteners to keep them up from the gunk. The poor, who often wore secondhand clothes, suffered from smallpox and other diseases spread by fabric that was recycled without being properly washed.

## 3. Flowing Skirts

Giant, ruffled, crinoline-supported skirts may have been fine for ladies of leisure, but they weren’t a great combination with industrial machinery. According to David, one mill in Lancashire posted a sign in 1860 forbidding the “present ugly fashion of HOOPS, or CRINOLINE, as it is called” as being “quite unfitted for the work of our Factories.” The warning was a wise one: In at least one printing office, a girl was caught by her crinoline and dragged under the mechanical printing press. The girl was reportedly “very slim” and escaped unharmed, but the foreman banned the skirts anyway. Long, large, or draped skirts were also an unfortunate combination with carriages and animals.

## 4. Flammable Fabrics

The flowing white cotton so popular in the late 18th and 19th centuries had dangers to both maker and wearer: It was produced with often-brutal slave labor on plantations, and it was also more flammable than the heavy silks and wool favored by the wealthy in the previous centuries. One type of cotton lace was particularly problematic: In 1809 John Heathcoat patented a machine that made the first machine-woven silk and cotton pillow “lace” or bobbinet, now better known as tulle, which could catch fire in an instant. The tulle was frequently layered, to add volume and compensate for its sheerness, and stiffened with highly combustible starch. Ballerinas were particularly at risk: British ballerina Clara Webster died in 1844 when her dress caught fire at London’s Drury Lane theatre after her skirt came too close to sunken lights onstage.

But performers weren’t the only ones in peril: Even the average woman wearing the then-popular voluminous crinolines was at risk of setting herself ablaze. And the “flannelette” (plain cotton brushed to create a nap and resemble wool flannel) so popular for nightshirts and undergarments was particularly combustible if hit with a stray spark or the flame of a household candle. So many children burned in household accidents that one company came out with a specially treated flannelette called Non-Flam, advertised as being “strong’y recommended by Coroners.”

## 5. Arsenic-Ridden Taxidermy

Dead birds were a popular addition to ladies’ hats in the 19th century. According to David, “fashions in millinery killed millions of small songbirds and introduced dangers that may still make some historic women’s hats harmful to humans today.”

But it wasn’t the birds that were the problem—it was the arsenic used on them. Taxidermists of the day used arsenic-laced soaps and other products to preserve birds and other creatures. In some cases, entire birds—one or several—were mounted on hats. Some Victorian fashion commentators decried the practice, though not because of the arsenic involved. One Mrs. Haweis, a writer on dress and beauty, began an 1887 diatribe against “smashed birds” with the sentence: “A corpse is never a really pleasant ornament.”

## 6. Mercury

No upper-class man of the Victorian era was complete without his hat, but many of those hats were made with mercury. As David explains, “Although its noxious effects were known, it was the cheapest and most efficient way to turn stiff, low-grade fur from rabbits and hares into malleable felt.” Mercury gave animal fur its smooth, glossy, matted texture, but that velvety look came at a high cost—mercury is an extremely dangerous substance.

Mercury can rapidly enter the body through the skin or the air, and causes a range of horrible health effects. Hatters were known to suffer from convulsions, abdominal cramps, trembling, paralysis, reproductive problems, and more. (A chemistry professor studying toxic exposure at Dartmouth College, Karen Wetterhahn, died in 1996 after spilling just a few drops of a supertoxic type of mercury on her glove.) To make matters worse, hatters who drank while they worked (not an uncommon practice) only hastened mercury’s effects by hampering the liver’s ability to eliminate it. While scholars still debate whether Lewis Carroll’s “mad hatter” was meant to show the effects of mercury poisoning, his trembling limbs and wacky speech seem to fit the bill.

Pallor was definitely in during the Victorian era, and a face spackled with lead white paint was long favored by fashionable women. Lead had been a popular ingredient in cosmetics for centuries, David writes, because it “made colors even and opaque and created a desirable ‘whiteness’ that bespoke both freedom from hard outdoor labor and racial purity.” One of the most popular lead-laced cosmetic products was called Laird’s Bloom of Youth; in 1869, one of the founders of the American Medical Association treated three young women who had been using the product and temporarily lost full use of their hands and wrists as a result. (The doctor described the condition as “lead palsy,” although today we call it wrist drop or radial nerve palsy, which can be caused by lead poisoning.) One of the women’s hands was said to be “wasted to a skeleton.”

It’s no surprise that some fans are having a hard time dealing with the fact that Game of Thrones is over. The show ran for eight seasons, and became a huge part of fans's lives and Sunday night routines. Moreover, since the season 8 premiere first aired, fans haven’t been too thrilled with the trajectory of the show, and it has only gotten worse. (The final episode in the series scored the lowest rating in the show’s history on IMDb).

But if you’re having a hard time wrapping your mind around the end of Game of Thrones, or just want to vent, there's a counseling service here just for you. CNN reports that if you go to Bark.com, a UK-based online marketplace, you can find a Game of Thrones counselor who will listen to your every qualm about the show. "The professionals will help them digest their feelings and interpretation of the show, which could range from anger and confusion to sadness and grief," the service description reads.

"We watch them to escape our daily lives and immerse ourselves into the 'unknown,'" Lynette, a counselor from Bark.com, said in a statement regarding people's TV show obsessions. "This is the very reason why we sometimes become addicted to watching them, the stories they tell become part of our identity."

There’s options of booking a 30-minute or 60-minute session, which range from \$25 to \$51. Fans can choose from a face-to-face session, group session, or online, and can specify which specific problems they’re having regarding the show.
