The Great Pyramid of Giza was built with such precision that the biggest margin of error was 58mm!

The Great Pyramids of Giza are world-renowned structures. The largest and oldest of the three pyramids is the Great Pyramid. It is the oldest of the Seven Wonders of the Ancient World. It is thought that it was built as a tomb for the Egyptian Pharaoh Khufu.

It was built over a period of 10-20 years. Upon completion, it stood at 480.6 feet tall. For 3,800 years, it was the tallest man made structure in the world. Each side of its square base is about 756 feet long. While the sheer size of the pyramid is impressive, the accuracy of the construction is just as astounding. On each of these four sides, the average error is just 58 millimeters.

The base is horizontal and flat and has an error of only 15 millimeters. Similarly, the base was squared to a mean corner error of only 12 seconds arc. The four sides of the base point to the four directions, north, south, east and west.


When it was built, the Citicorps center had a high chance of falling down. The engineers fixed it without telling anyone!

The Citicorps Center was built in the 1970s in New York City. At it's completion it was the 7th tallest building in the world. William J. LeMessurier was the structural engineer on the project. Only a year after it was built it became apparent that the Citicorps Center could only withstand a sixteen-year-storm, meaning it had a one in sixteen chance that it would totally collapse every year.

Originally it was meant to be able to withstand a one in fifty-five-year-storm. The problem was easily a career ender for LeMessurier. Instead of ignoring the problem or simply committing suicide to get out of the problem, LeMessurier decided to take responsibility, but secretly.

He hatched a plan that involved workers to fix all 200 joints of the building's structure, hired people to oversee the work carefully and make sure it was done properly, and then hired 2,000 Red Cross workers to help evacuate the building should something have gone wrong. He managed to do it without anyone knowing for twenty years.

The information finally came out in the late 1990s and LeMessurier was able to keep his reputation sound and ended up making Citicorp Center the strongest building in the world able to withstand a 700-year-storm.


The 17 Strangest Animal Facts Ever Published

A species of octopus loses its penis during sex.

The Argonaut octopus has a lot of sex, but it never directly experience sex.

This is because it reproduces via tele-sex. The male octopus produces sperm in its penis.

The penis is then detached (yes, detached) from the body and swims (yes, swims) by itself to a suitable female.

The female is automatically impregnated by this detached, swimming penis.

The most the male can do is sit back and watch as his disembodied junk carries out the sex out for him.

After all of this, the male begins to regrow his penis, which is often a very slow, tedious process.


Buzz Aldrin's Mother's maiden name was Moon!

Talk about irony...or was it destiny? Buzz Aldrin was a Jersey boy born in 1930. He grew up in New Jersey and graduated a year early from high school taking him straight to West Point where he graduated third in his class with a BS in mechanical engineering.

He joined the Air Force and flew F86 Sabre Jets in 66 combat missions in the Korean War. He was decorated with the Distinguished Flying Cross for his work in Korea. He did a tour of duty in Germany flying F100s and then returned to the U.S. where he got his Doctorate of Science in Astronautics at MIT.

He wrote his thesis on Manned Orbital Rendezvous. He was well chosen by NASA in 1963 into the third group of astronauts and the only one with a doctorate. This is where we all know him from, of course.

Ironically, Aldrin's mother was named Marion Moon! He then was chosen by NASA to become an astronaut and one of the first two people to ever set foot on the moon. Aldrin was a pivotal piece in NASA's space program. He came up with the idea of using underwater training as a substitute for zero-gravity flights and the docking and rendezvous techniques he made for the spacecraft and lunar orbit were critical in the success of the Gemini and Apollo programs. His techniques are still used by NASA today.


Bender from Futurama has the same microprocessor as the original Nintendo!

The 8-bit microprocessor MOS Technology 6502 was designed in 1975 by Chuck Peddle and Bill Mensch. It was much less expensive than the 8-bit microprocessors bigger companies like Motorola and Intel had come out with. It was also just a good as their products were.

It was the MOS Technology 6502 along with the Zilog Z80 that started the computer projects that eventually led to the home computer revolution of the 1980s. Just think, had this microprocessor not been made so affordable and well, we wouldn't have Halo or Call of Duty or even The Last of Us. It was the beginning of more than they knew.

So, in the 1980s the Atari, Apple II, and other home gaming consoles started popping up. The MOS Technology 6502 has been made in famous pop culture references, too. In the 1984 The Terminator, featuring the one and only Arnold Schwarzenegger, the audience is given a view through the T-800 Model-101 robot character's eye camera of a display of a 6502 assembly language program fragment several times.

The industrial robot, Bender, from Fox's Futurama is manufactured in the year 2998 and it was revealed in the episode "Fry and the Slurm Factory" that Bender had a 6502 as his brain. The head writer and producer of Futurama, David X. Cohen, said that he and his friends wrote a compiler for the Apple II Plus using a 6502 in high school, and that is where he got the idea for Bender's brain.
