8 Facts You Learned at School that Are No Longer True!
The passage of time can make even the most steadfast of facts to no longer be true. For instance, it was once believed that doctors didn’t need to wash their hands before surgery, but it’s now known that doing so is imperative in order to prevent infection. Take a look at 8 supposed facts that aren’t really true:

1. THEN: America won its independence on July 4, 1776.
NOW: America didn’t officially gain independence until 1783.
July 4th marks Independence Day in the United States, and it’s a celebration replete with parades, barbecues and fireworks. Although the Declaration of Independence was adopted by 12 colonies on July 4th, 1776 and signed by 13 colonies the following August, America was still under British rule. The American Revolution raged on until September 3rd, 1783, when the Treaty of Paris was signed and America truly became free.

2. THEN: George Washington's teeth were made of wood.
NOW: His teeth were actually human teeth from his slaves. Some were made from ivory.
A set of dentures worn by George Washington are kept at the Mount Vernon plantation house museum. They’re fashioned out of ivory and human teeth, with the human teeth being purchased from slaves that sold them to dentists to make some money in the 18th Century. Apparently Washington paid just one-third of the going rate for the teeth. It’s likely that Washington had his dentures implanted into his jaw.

3. THEN: Pluto is a planet.
NOW: Pluto isn't a planet.
Pluto was discovered by Clyde Tombaugh back in 1930. He submitted his finding to the Harvard College Observatory, which allowed an 11-year-old English girl to give the newly discovered planet its name. In 2003, an astronomer found that there was an even larger object beyond Pluto, and he named it Eris. This sparked a debate regarding the criteria for what makes a planet a planet. Following the debate’s conclusion, astronomers decided that neither Pluto nor Eris made the cut, so Pluto was demoted to dwarf planet status.

4. THEN: Diamond is the hardest substance.
NOW: Ultra-hard nano-twinned cubic boron nitride is the hardest substance.
It’s been known that there are two substances that are harder than diamond since 2009. These substances, known as wurtzite boron nitride and lonsdaleite, are 18% and 58% better at resisting indentation than diamond respectively. The only problem is that they’re both quite unstable and rare elements. Yet another substance that’s even harder than the aforementioned two was discovered by researchers in 2013. Called ultra-hard nano-twinned cubic boron nitride, it essentially consists of boron nitride particles that have been reorganized into the shape of a layered onion.
