Nikola Tesla, who was born on this day in 1856, has long been a fascinating and enigmatic figure. While his contributions to science went underappreciated for years, his work is finally being recognized, and the compelling details of his personal life keep interest in him alive. Here are a few highlights from his intriguing life.

1. HE HAD A TREMENDOUS TALENT FOR VISUALIZING INVENTIONS—BUT WAS ALSO PRONE TO OTHER STRANGE VISIONS.

Tesla was able to visualize objects, including inventions he was building, in his head, down to the minutest detail. His method of working was pretty unorthodox compared to other inventors, as he rarely created sketches or drawings, relying instead on the power of his own imagination to work out details. Beginning in early childhood, Tesla experienced flashes of light, which were sometimes followed by inspiration or solutions to problems. These visions could sometimes take on the character of a spiritual experience, but Tesla, a man of science, discounted any such interpretation, valuing them only for their scientific benefit. 

2. HE PIONEERED MANY SIGNIFICANT MODERN INVENTIONS BEYOND ALTERNATING CURRENT.

For many, Tesla is associated with the “War of the Currents”—waged with onetime employer and later rival Thomas Edison—over the form of electricity that would become standard. Edison championed direct current, or DC, while Tesla and ally George Westinghouse fought for alternating current, or AC. AC, of course, eventually won out over DC, despite Edison’s attempts to malign Tesla’s invention by pushing the electric chair as a method of execution to show how dangerous AC was. However, Tesla also conducted pioneering work in electric light, electric motors, radio, x-ray, remote control, radar, wireless communications, and robotics, and created his famous transformer, the Tesla coil. Tesla was in many cases not properly recognized for his contributions, with other inventors receiving credit for improving on what he began. He obtained around 300 patents in his lifetime.

3. HE HAD EXTREMELY REGULAR, EVEN OBSESSIVE-COMPULSIVE, HABITS, AND WAS A GERMAPHOBE.

Throughout his life, Tesla displayed a formidable work ethic, keeping a regimented schedule. Some claim he slept only two hours a night. He often took his dinner at the same table at Delmonico’s in New York, and later at the Waldorf-Astoria hotel. He had an all-consuming fear of germs and required a stack of 18 napkins. He was obsessed with the number three, and was prone to carrying out compulsive rituals related to three. When he was young, he would develop a fit at the sight of pearls, and couldn’t bear to touch hair.

4. HE CLAIMED TO HAVE NEARLY CREATED AN EARTHQUAKE IN MANHATTAN.

Tesla’s electro-mechanical oscillator, a steam-powered electrical generator, was developed as a possible replacement for inefficient steam engines used to turn generators, but couldn't compete with steam turbines. Tesla reportedly regaled friends with a tale in which his experiments with the oscillator at his lab at 46 East Houston Street in Manhattan set off vibrations that generated a resonance in several neighboring buildings, shaking the ground and prompting calls to police. When the machine began oscillating at the resonance frequency of his own building, Tesla surmised that he was in danger of creating an earthquake, and allegedly smashed the device with a sledgehammer. The claims—which earned the machine the nickname “Tesla’s Earthquake Machine”—were later debunked by Mythbusters (the team felt vibrations from hundreds of feet away using a re-creation of Tesla's machine, but didn't create any earthquakes).

5. HE ELECTRIFIED BUTTERFLIES AND BLEW OUT POWER STATIONS IN COLORADO.

Tesla moved his operations near Colorado Springs in 1899 in order to take advantage of the great amount of space available for experimentation and the free supply of AC power he had been offered there by the El Paso Power Company—and because he believed the thin atmosphere might be conducive to his goal of wireless power transmission. Experiments in a lab with an 80-foot tower, 142-foot metal mast, and enormous Tesla coil formed massive bolts of artificial lightning that supposedly created thunder and errant sparks 15 miles away, surprising people and frightening horses, and surrounding butterflies with halos of St. Elmo’s fire. The bolts also blew out dynamos at a local power company and caused a blackout. It’s not clear if Tesla succeeded in the wireless transmission of power, however.

6. HE WAS A SNAPPY DRESSER AND ATTRACTED THE LADIES.

By all accounts, Tesla was a striking individual. At 6 foot 2 and just over 140 pounds, he was very tall and slender, with dark, deep-set eyes. He was also a fashionable and fastidious dresser, and while he could be reclusive while deeply engaged in work, he was fascinating company when he felt like being social. Not only did he attract the friendship of famous people like Mark Twain, but he also drew the attentions of women, some of whom confessed to being “madly in love” with him. Much of Tesla’s personal life remains a mystery, however, and he never married.

7. HE DIDN’T REALLY SIT IN A ROOM SURROUNDED BY LIGHTNING BOLTS.

That famous photo of Tesla sitting on a chair in his laboratory and calmly examining his notes while tremendous bolts of lightning flash around him was likely the result of a double exposure. Yet the image, taken at his Colorado lab and used as publicity to generate capital for new projects, captures the public’s fascination with a scientist whose prowess made him seem a magician to many. 

8. HE WANTED TO ILLUMINATE THE ENTIRE EARTH, LITERALLY.

Tesla believed that his work had the potential to light the Earth’s atmosphere, banishing darkness and bringing in a new era of light. He theorized that gases in Earth’s upper atmosphere were capable of carrying high-frequency electrical currents, and successful transmission of such currents there could create a “terrestrial night light” that would make shipping lanes and airports safer and illuminate whole cities. But like most of Tesla’s loftier aims, this goal was never realized, and its possibility remains unproven. 

9. THE SECRET PURPOSE OF HIS GIANT TOWER ON LONG ISLAND WAS THE WIRELESS TRANSMISSION OF POWER.

As the 20th century arrived, Tesla was locked in a race with Italian inventor Guglielmo Marconi to be the first to transmit messages across the Atlantic Ocean. Tesla began securing funding, much of it coming from financier J.P. Morgan, to build a wireless transmission station on Long Island with a massive, 186-foot tower. The station would be called Wardenclyffe. Tesla, however, had his own agenda. He wanted to use Wardenclyffe to fulfill his long-held dream of transmitting electricity wirelessly. When Marconi beat Tesla to the punch in 1901, transmitting the letter s across the Atlantic with much more modest equipment, Tesla was forced to reveal his ulterior motives to Morgan and to beg for additional funding to complete his tower. Morgan, however, indicated that he was no longer interested in the project and pulled his support. This move, along with other factors, would ultimately spell the project’s doom. 

10. WARDENCLYFFE IS BEING TURNED INTO A MUSEUM.

Wardenclyffe fell into disrepair after the collapse of Tesla’s ambitions there and destruction of its tower in 1917. The main building, designed by architect Stanford White, remained and was alternately left abandoned or used for industrial purposes. Nonprofit group The Tesla Science Center at Wardenclyffe began a successful crowdfunding campaign in 2012 with the goal of buying the property, and closed the deal in 2013. A plan is underway to convert the site into a Tesla museum and science education center, with work ongoing. The site is not yet open to the public, but visitors are allowed for special events, like Tesla’s birthday celebration in July.

5 Ways to Keep Your Dog Calm on the Fourth of July

The Fourth of July can be rough for dogs. Fireworks displays light up their senses with unfamiliar noises, flashes, and smells, and parties flood their homes with strange guests who may invade the rooms they usually have as private retreats. And when distressed dogs escape, howl, or thrash around the house, Independence Day can quickly become a nightmare for their owners, too. To minimize Fido's stress this holiday, we spoke to some dog experts to discover the best ways to keep your canine calm on the Fourth of July.

1. Exercise Your Dog

Anthony Newman, the dog whisperer who runs New York City's Calm Energy Dog Training, says that exercise is a great way to help your dog let off some nervous energy. "Whenever Fido is going to be neglected for an extended period of time, or around any stressful stimuli, it always helps to tire him out just before—and even during the night if you can," Newman says. "As the saying goes, a tired dog is a good dog! He'll be calmer, happier, and more peaceful."

2. Keep Your Dog Indoors

Dr. Stephanie Liff, head veterinarian at Pure Paws Veterinary Care, says the best place to keep your pet during a fireworks show is inside and away from the windows. "If the pet is very scared, an escape-proof crate or a sound-insulated room, such as an internal bathroom, may help the pet to feel more secure," Liff tells Mental Floss. "If you cannot keep your pet inside, make sure that the pet is prevented from escape (monitor all exits and tell guests to monitor your pet)."

3. Socialize Your Dog

While your dog may feel more secure in a room away from all the noise, Newman points out that keeping your dog isolated in another room for too long can be stressful for your pet. "Release his curiosity and let him in on the fun, to run around and play with both two-legged as well as four-legged guests," Newman says. "Then back to his obedient room, bed, car, crate, or spot. Rinse and repeat as needed throughout the night."

4. Take Control of Your Dog

According to Newman, the best way to keep your dog calm during the chaos of July 4th is to stay in charge. "If your dog winces, shivers, and runs away at loud noises, the last thing he wants is to feel like nobody else is looking out for him," Newman says. Don't let your dog run rampant around the house or follow him around trying to soothe him. Instead, Newman says it's important to "take control by attaching a super-light leash that you can grab and lead him whenever you need."

5. Explore Medicating Your Dog

In extreme cases of nervousness, Liff says that you should talk to your vet about medication to sedate your dog.
