Hedy Lamarr the actress was also an inventor. She was the one that came up with using frequency hopping and spread spectrum radio signal to prevent signal jamming to torpedoes. Her work is the foundation of WiFi, CDMA and Bluetooth.

Hughes often consulted her on his planes as well.

I wanted to post something about the Pythagorean theorem from "The math book" written by Clifford A. Pickover about that hindi mathematicians already used and developed at 800 BC, the theorem and that the babelonians in Mesopotamia used the Pythagorean theorem in 1800BC, at least it was described on a clay tablet called Plimpton 322 from that era. I just found out that the wikipedia page has the information as well.

The decimal system was developed by Hindi mathematicians (1,2,3,4,5,6,7,8,9 and later the 0 by mathematicians such as Brahmagupta, Mahavira and Bhaskara.)
During the Islamic golden age, the Persian mathematician Abu Ja'far Muhammad ibn Musa al-Khwarizmi developed Algebra.

Al Uqlidisi was a Arabic mathematician who created the writing style of units, tens, hundreds, etcetera as we know today.

Leonardo of Pisa AKA Fibonacci was responsible for introducing the Hindi Arab numbers and the decimal system in western europe.
That was a huge advancement over using the roman numerals.

EDIT:
Forgot to mention, if you believe the universe is a mathematical construct, The articles of Max Tegmark might interest you.

Wow, I had no idea this thread existed!

Every year in October scientists, writers and activists are awarded the Nobel Prize for outstanding achievement in their field. In 1949, a Portugese neurologist won the award for inventing a procedure known as the lobotomy. It involved severing nerve connections within the brain. Today the lobotomy is considered a barbaric treatment for mental illness, and that's why relatives of lobotomy patients now have started a campaign to have the prize

for some reason some people want to rescind this Nobel Prize. http://www.npr.org/templates/story/story.php?storyId=4794007

I hope mine is not a repeat.

A huge 60m hidden void has been discovered in the great pyramid in Egypt.

PEERING INTO THE PYRAMID Using muon detectors installed inside and outside the pyramid (positions indicated with asterisks), researchers uncovered a mysterious void above the Grand Gallery. No one knows what the cavity is for, or even whether it consists of one or multiple chambers.

Researchers probed the Great Pyramid’s interior with devices that sense muons — by-products of spacefaring subatomic particles called cosmic rays striking atoms in the atmosphere. Muons continuously rain on Earth at nearly the speed of light. But while the subatomic particles easily streak through open air, rock can absorb or deflect them. By placing detectors near the base and areas deep inside of the Great Pyramid and measuring the number of muons that reach the detectors from different directions, scientists could spot empty spaces inside the ancient edifice.

For instance, if a detector inside the pyramid picked up slightly more muons from the north than the south, that would indicate there was slightly less rock on the north side to intercept incoming muons. That relative abundance of muons could indicate the presence of a chamber in that direction.

Muon imaging an enormous, dense construction like the Great Pyramid “is not an easy game,” Akchurin says. The monument obstructs 99 percent of incoming muons before the particles can reach detectors, so collecting enough data to spot its hollow spaces takes several months.

The newly identified void was first seen with a type of muon detector called nuclear emulsion film, which the researchers laid out in a space called the Queen’s chamber and the adjacent corridor inside the pyramid. When muons zip through these films, the particles’ chemical interactions with the material leave silver trails that reveal which direction the particles came from, explains Elena Guardincerri, a physicist at Los Alamos National Laboratory in New Mexico not involved in the work.

Elvis was known as The King of Cats to the Chinese. No clue why.

One possibility is HK people translating "Hillbilly Cat" to "Cat King" :shrug:

What happened to fecal matter in medieval Britain? Have some sh**ty history.

http://www.todayifoundout.com/index.php/2017/11/people-middle-ages-really-just-poop-window/

excerpt:

In more affluent homes that had rudimentary plumbing, the two p’s would make their way to either a private or communal cesspit, often buried underground to reduce the smell.

These cesspits, or gongs as they were known (from the Old English “gang”, meaning “to go”), were designed such that the liquid waste would be absorbed into the surrounding soil (occasionally conveniently located near public wells…) while the solid waste would accumulate over a period of many months. Ultimately, these then needed to be emptied by hand- a job commonly performed by individuals known as “gong farmers”.

Perhaps unsurprisingly given their profession, gong farmers were exceptionally well-paid, sometimes earning in a day what most labourers earned in a week, and in times of plague potentially even more. They also infrequently found valuables amongst the waste that they were free to keep, though it’s noted that they also occasionally found skeletons from murder victims and unwanted babies. So, yeah…

Some information about water flouridation - no, it's not bad for you

So what is the recommended intake of fluoride? That depends on your age. Since almost all nutrients needed are based on an amount proportional to your mass (in this case measured in weight), the older you get, the more per day you need. For example, infants 0-6 months need about .01 mg/day. At 4-8 year of age you need about 1mg/day, and at 9-13 need about 2mg/day. Over the age of 19 and the amount is around 4mg/day for men and 3mg/day for women.

As previously mentioned, fluoride is found almost everywhere, including your food. For example, when you consume 100 grams of table wine, you’ll also be naturally consuming about 0.2 mg of fluoride; with 100 grams of seedless raisins about 0.23 mg, the same amount of brewed tea gives you 0.37 mg, and cooked crustaceans, like crab and shrimp, 0.16 mg.

The very fact food and drink (non tap water) has fluoride in it means you don't need the government to add yet even more. In my town they actually reduced the amount they poison you with. Now go back to the 1800s where the pure Colorado Rockies water wasn't tainted at all.

This is like salt. You need salt because they add the human body needed iodine. But damn near every freaking thing you eat already has salt.

So my diet is sea salt and cases of bottled water. Yes, the bottled water I buy is just filtered tap water. But that's what I want. Filtered water. Not in the market for a pitcher or faucet filter. And the hose on my fridge broke so it's a real bitch filling my glass bottle. I drink no less than 7 bottles a day. LOL

... What filtered water are you drinking? Chances are they did not remove flouride.

You need a home distillation unit like this - https://smile.amazon.com/Water-Mini-Classic-CT-Counter-Distiller/dp/B01FVEFO6O

It draws about 700w and takes a little over 3 hours to make roughly 3 quarts. I make about one batch per day on average.

Drinking distilled water is bad for you.

 

[Charmonium]

Please elaborate.

The only thing I really worry about are volatile organic compounds escaping into the air during the distillation process. Any that condense back to liquid should get trapped by the carbon filter but I'm sure some escape.

Adding pure solvent to your system = drawing out whatever is in you and getting rid of it when you pee. So electrolytes, vitamins, etc. Just adding a little salt is good enough, not even enough to taste it level.

Hmmm. The bottle says, "processed by advanced filtration, ozone and, reverse osmosis technologies.

So I'm guessing the water doesn't have all that crap, but I wouldn't doubt that it does. It's the Kroger brand water.

You'd be wrong.

Flouride in the quantities humans consume is not a poison. If you want to find something to get bent out of shape over, pick something rational like air quality or sugar prevalence or something.

Well, reading that it pretty much states that if the bottled water I do drink contains fluoride, it would be trivial. If any at all.

Also. "preventing tooth decay and promoting oral health."

So the body doesn't need it like I thought. Just your teeth. And I get plenty of that crap from Crest. I do like to alternate between baking soda one day and tooth paste the next. I don't believe in using tooth paste continuously. But that's just me. Albeit, toothpaste has its benefits. And so does baking soda.

You do know that pure fluoride is great at getting rid of say, a body...? The stuff is caustic as all hell.

Did you know the most popular color for washers and dryers is... plain white? It's so popular that for some brands every shell gets painted white automatically on the line. The other colors are done on another line after this step, and are often sourced from the rejected white painted ones. So if you have a color other than white, chances are good that something was wrong with the initial white coat and was just painted over with color to save it.

Avocado is best.

Blasphemy! I love guacamole. And I love sliced avocado or guacamole in fajitas.

I think avocados are heart healthy.

Although, I've heard that in Mexico they may use sewer water for watering the trees. LOL Not sure how true, but it wouldn't surprise me.

My mom ate avocados from a tree in her front yard where her dogs peed around it all the time. I declined when she'd offer them to me, but I didn't tell her why.

Tiny gunfights under the ocean. The thug life of pistol shrimp.

This reef ain’t big enough for the both of us. Two pistol shrimp face each other, each spreading open its giant snapping claw – nearly half the size of its body. One or both of them then snaps the claw shut in its opponent’s direction, firing off a powerful water jet at speeds up to 30 metres per second.

These shrimp shootouts are rarely fatal, but can leave the loser retreating with missing claws or puncture wounds. But the high-speed squirt isn’t what harms their target – it’s the resulting shock wave. Now we have glimpsed how this unfolds in fine detail.

If you stick your head under coastal tropical waters, you may hear a sound like chestnuts crackling as they roast. At a volume of about 200 decibels – louder than a .22 calibre rifle shot – these pops are some of the loudest in the ocean, second only to sperm whale clicks.

Originally, marine scientists thought the sounds were produced by the impact of the shrimps’ claws closing. Now, we know that they ring out when an air bubble collapses around the watery salvo, much as when bubbles form in our joints and rapidly collapse as we crack our knuckles.
