Singing Tesla coils

In the early 2000s, engineers discovered that Tesla coils could emit tones by modulating the sparks themselves. When programmed, they could play songs using bursts of lightning as notes.

Audiences watched and listened as glowing bolts of electricity "sang" familiar tunes like movie themes. These displays, part science and part spectacle, were a short-lived trend, but they were interesting while they lasted.

Franklin’s glass armonica

Benjamin Franklin invented many things. Among them, a glass armonica, using spinning glass bowls tuned by size . Players touched the rims with wet fingers to produce pure, haunting tones that seemed to shimmer in midair.

Its ghostly beauty amazed 18th-century audiences. Yet rumors spread that the vibrations could cause fainting or madness, making the momentum of the instrument short-lived.

Harry Partch’s microtonal instruments

Frustrated with the limits of Western scales, composer Harry Partch built a system using forty-three tones per octave . He crafted odd instruments from glass, bamboo, and metal to play them.

Performers had to relearn music from scratch, producing sounds that felt alien and ancient at once. His homemade orchestra became a true milestone in America’s experimental environment.

The Stroh violin

Back in the days when microphones were not so great at picking up sounds, early studios struggled to capture soft instruments. The Stroh violin solved that by replacing the wooden body with a brass horn that amplified sound directly .

Its brassy, nasal tone worked perfectly for primitive recording gear. Once technology advanced, the mechanical violin faded for good.

Singing saw

Rural American musicians once discovered that a regular handsaw could "sing" when bent and bowed like a violin . The flexible steel vibrated with a haunting, "human-like" voice.

The sound carried through old-time folk, gospel, and early film scores. Even today, the singing saw appears in grassroots festivals and soundtracks.

The Singing Nun

In 1963, a Belgian nun named Sister Luc-Gabrielle unexpectedly topped U.S. charts with "Dominique," sung in gentle French. Her purity and optimism charmed listeners across the country.

Her hit briefly outshone even the Beatles. Though her fame faded quickly, the story of a shy nun reaching number one remains a sweet oddity, for sure.

The "Longplayer" experiment

Launched in 1999, "Longplayer" is a music piece designed to play continuously for one thousand years without repeating . It was created by American artists who joined the project to maintain its endless cycle.

The music changes subtly with time, echoing life’s slow rhythm. Its creators call it "a conversation between centuries".

George Washington’s father, died when he was just 11 years of age. There isn’t much information about his childhood and most of his virtues and qualities were invented by an admirer after he passed.

However, we do know one thing: George Washington was mostly self-educated since there was little money to support formal education.

Most of his knowledge and education came from his curiosity and eagerness to learn and become a better soldier, then farmer, and, in turn, president.

First Official Job

Image: Matt Briney

Since he lost his father at such an early age, Washington started working very young. His first official job was as a surveyor, which was a pretty respectable job for the 18th century. His aim in this job was to measure the land.

At the age of 16, he took on an expedition across Virginia’s western frontier in order to map the land. This experience provided him with a deep understanding of the land, the resources, and the insight he would later need in his political and military career.

At the age of 19, George Washington accepted going on a trip to the tropics with his half-brother Lawrence who was suffering from tuberculosis.

Now, during this trip, Washington kept a diary in which he narrated his days on the ship and the island of Barbados, confessing being struck by the beauty of the place. The trip went South shortly after his arrival: On the island, he contracted smallpox, a dreaded disease during the 18th century.

Curious enough and dreadful as it was, this gave him immunity which ultimately saved him from death during the Revolutionary War, since smallpox rapidly spread across his army.

Agriculture Innovator

Image: Raphael Rychetsky

It is no surprise that Washington was an innovator, a forward-thinking kind of person. Besides politics and, as we learned, whiskey, he was also interested in technology.

In the 1760s, he went from growing tobacco to cultivating wheat, which revolutionized the farming practices in his estate. He experimented with crops, fertilizers, and tools to improve productivity.

He didn’t keep innovations for himself: As a president, he patented Oliver Evans’s automated mill technology, and he designed a 16-sided, two-story threshing barn that enhanced the efficiency of wheat processing.

Washington is the only president to have never lived in the White House! He, together with his family, lived in different houses along New York and Philadephia where he used to receive members of Congress, officials, and people of the sort.

The Residence Act, which moved the capital from Philadelphia to a new city along the Potomac River (later named Washington, D.C.), actually set the White House as the official presidential residence.

Only President To Have a State

Image: Vlad Tchompalov

Have you ever noticed that there is no Lincoln State or Jefferson State? George Washington is the only U.S. President to have a state named after him .

As a Founding Father, the first President of the United States, Hamilton, Madison, and Jefferson thought it was necessary to pay homage to his great contributions by naming a state after him.

Together with the president’s name, the state of Washington is named Columbia, after the female personification of the country.

First To Sign The Consitution

Image: Anthony Garand

George Washington is a Founding Father, and we all know that. As such, he was deeply involved in the writing of the Articles of Confederation, the first frame of government.

He suggested changes and his voice was regarded in the highest esteem by his fellow countrymen. In this sense, he was chosen president of the Constitutional Convention which took four months and gave, as a result, the Constitution of the United States. In his role as president, Washington was given the privilege of signing the governing document first .

He Was a Natural Entertainer

Image: Adam Nemeroff

When you look at pictures of Washington, you may think he was unapproachable, stiff, and serious, but history tells us otherwise.

According to many accounts, he actually loved entertaining and welcoming guests, and having company. Parties, cotillions, balls, these kinds of events were a perfect opportunity to combine entertainment and dancing, which he also enjoyed. Did you know this?

Post-retirement Hobby

Image: Thomas Park

Of course, they are considered national heroes, but the Founding Fathers were people with diverse interests and pursuits. George Washington was not the exception and, after he retired he took up a most interesting hobby: whiskey.

Once he ended his life in politics, he built up a whiskey distillery where he created whiskey from rye, corn, and barley. Even if it began as a hobby, the distiller became one of the most productive in the nation and, by the time he died, it remained as one of the largest.

One-Dolar Bill Face

Image: Marek Studzinski

Washington’s portrait on the one-dollar bill was inspired by a painting created by Gilbert Stuart. Back in 1795, Stuart painted Washington, but this piece of work comes with a few curious facts.

The first one is that the work is known only from copies. The second is that the painting was so successful that Washington’s wife commissioned a second portrait for herself. However, the painter never finished the first commission and kept it as a reference for future work.

That incomplete painting, known as the "Athenaeum," served as the reference for creating the portrait on the dollar bill.
