The Amazing Unfinished And Abandoned 1000 Ton Egyptian Obelisk

The amazing unfinished and abandoned 1000 ton Egyptian Obelisk

The largest known Egyptian obelisk is called the “unfinished obelisk”, which today can be found exactly where it was once semi-carved from the solid bedrock. This stone block was intended to be a 120ft tall obelisk. It is estimated that a block of granite this size would easily weigh more than a 1000 tons, some geologists have suggested a figure in the region of 1100 tons – 1150 tons.

Residence in Woody Creek, Colorado

Perched at the rivers edge, this Pampiano Residence by Studio B consists of an addition to the existing house as well as a detached garage with a dwelling unit above. The new architecture reinterprets the existing house and marries the project as ‘a whole’ through its use of materials, patterns and massing.

How To Be A Troll, And Win Wars

Under Sun Pin’s direction the Ch’i armies, which were advancing into Wei, followed the dictum “Be deceptive.”

P’ang Chüan arrogantly believed the men of Ch’i to be cowards who would flee rather than engage mighty Wei in battle. Therefore, Sun Pin daily reduced the number of cooking fires in the encampment to create a facade of every-increasing desertion. He also effected a tactical withdrawal to further entice P’ang Chüan into the favorable terrain at Ma-ling where the Ch’i commander concealed ten thousand crossbowman among the hills.

P’ang Chüan, apparently afraid that he would miss an opportunity to inflict a severe blow on the retreating Ch’i army, abandoned his heavy forces and supply train and rushed forth with only light units. Arriving at night, the combined Wei forces were ambushed as soon as they penetrated the killing zone.

In addition to being decisively defeated by Ch’i’s withering crossbow fire, 100,000 Wei soldiers needlessly perished because of their commander’s character flaws and hasty judgement.

The battle of Ma-ling is apparently the first recorded conflict in which crossbows were employed. The quote is taken from “Evolution of Conflicts and Weapons in China” in The Art of War by Sun Tzu.

I talked about the interesting structure of graphite (aka pencil lead) in our latest video:

But I didn’t have time to touch on one of the fascinating side effects of this structure - graphite’s conductivity. A single, two-dimensional sheet of graphite (known as graphene) is the most conductive material we know about. Diamond is among the least conductive materials we know about.

Impure graphite - like the stuff we find in pencils - is somewhere in between. It’s more conductive than sea water and less conductive than steel. As free electrons flow through it, it lights up like a filament and puts out a lot of heat.

Some risk-taking YouTubers (MausolfB Education and ElectroBoom) demonstrated this property so you don’t have to.

Memories Of Gonder Prior To Timket 2015. A Traditional Dancer At One Of Gonder’s More Famous Cultural

Memories of Gonder prior to Timket 2015. A traditional dancer at one of Gonder’s more famous cultural restaurants. The Tej made it all a blur but I had the presence of mind to pull out the xT1 and go up to some extreme ISO to try to make this pic. I am always inspired by Eskesta especially when done by some of the most beautiful woman on the planet… #Ethiopia #Ethiopian #EthiopianOrthodoxChurch #EthiopianOrthodoxTewahedoChurch #Timket #Timket2015 #culturaldance #Eskesta #Habesha #HabeshaCulture #PhotoToaster #fuji #fujifilm #fujixt1

Colliding Galaxies In Stephans Quintet : Will Either Of These Galaxies Survive? In What Might Be Dubbed

Colliding Galaxies in Stephans Quintet : Will either of these galaxies survive? In what might be dubbed as a semi-final round in a galactic elimination tournament, the two spirals of NGC 7318 are colliding. The featured picture was created from images taken by the Hubble Space Telescope. When galaxies crash into each other, many things may happen including gravitational distortion, gas condensing to produce new episodes of star formation, and ultimately the two galaxies combining into one. Since these two galaxies are part of Stephans Quintet, a final round of battling galaxies will likely occur over the next few billion years with the eventual result of many scattered stars and one large galaxy. Quite possibly, the remaining galaxy will not be easily identified with any of its initial galactic components. Stephans Quintet was the first identified galaxy group, lies about 300 million light years away, and is visible through a moderately-sized telescope toward the constellation of the Winged Horse . via NASA

Let's elect politicians who could pass a high school science class

I’m Re-posting This Comic Because I Live In America.

I’m re-posting this comic because I live in America.

Here, the places I love most in the world are gripped by drought. I’m thinking of giving away my winter tracking guides because there’s never enough snow. Climate change is knocking on our door, and the fact that it’s already so evident is a bad sign: it means that we’re headed for a lot more warming.

But we can deal with this, people. We’re brilliant. We’re brave. What we need - besides some kinda magical cooling ray - is a batch of elected officials who are ready to be brave alongside us.

If climate change bums you out, don’t lose heart: it means you’re strong. You’ve personally confronted a huge issue. Why let yourself be governed by scared people who can’t face it, who equivocate and attack scientists and hide their heads in the sand?

My brave dear friends: let’s get our climate vote on.

More Than Just Drawings

Artist and graphic designer Mike Okuda may not be a household name, but you’re more familiar with his work than you know. Okuda’s artistic vision has left a mark here at NASA and on Star Trek. The series debuted 50 years ago in September 1966 and the distinctive lines and shapes of logos and ships that he created have etched their way into the minds of fans and inspired many.  

Flight Ops

image

The Flight Operations patch has a lengthy history, the original version of which dates to the early 1970s. Having designed a version of the patch, Okuda had some insights about the evolution of the design.

“The original version of that emblem was designed around 1972 by Robert McCall and represented Mission Control. It later changed to Mission Operations. I did the 2004 version, incorporating the space station, and reflecting the long-term goals of returning to the Moon, then on to Mars and beyond. I later did a version intended to reflect the new generation of spacecraft that are succeeding the shuttle, and most recently the 2014 version reflecting the merger of Mission Operations with the Astronaut Office under the new banner Flight Operations.”

“The NASA logos and patches are an important part of NASA culture,” Okuda said. “They create a team identity and they focus pride on a mission.”

image

In July 2009, Okuda received the NASA Exceptional Public Service Medal, which is awarded to those who are not government employees, but have made exceptional contributions to NASA’s mission. Above, Okuda holds one of the mission patches he designed, this one for STS-125, the final servicing mission to the Hubble Space Telescope.

Orion

image

Among the other patches that Okuda has designed for us, it one for the Orion crew exploration vehicle. Orion is an integral of our Journey to Mars and is an advanced spacecraft that will take our astronauts deeper into the solar system than ever before. 

Okuda’s vision of space can be seen in the Star Trek series through his futuristic set designs, a vision that came from his childhood fascination with the space program.
