The Excellent Obelisk, Axum

Image by A.Davey
These are the remains of the &quotGreat Obelisk&quot at Axum in northern Ethiopia. Believed to be the largest object ever carved from a single piece of rock, the Great Stella is believed to have collapsed and shattered as it was being raised in antiquity. It was over 108 feet tall!

I wonder who explained it to the boss . . . and regardless of whether the boss was present at the collapse.

Modern day Axum in Ethiopia is built on and around the remains of an ancient city, the former capital of the Axumite Kingdom.

The Axumite Kingdom had emerged as a regional energy by the second century of the current era.

Axum reached its peak among the third and sixth centuries of the present era. Most people do not know that Axum was one of the most effective kingdoms on earth for the duration of its hayday, primarily because of its handle of trade routes on sea and on land.

These days, the stelae, or obelisks, erected by Axumite kings are the most impressive remains of that ancient society.

The late archaeologist Stuart Munro-Hay wrote a fascinating description of the obelisks at Axum, including the a single pictured right here.

——————————————————
Without having doubt, Aksum’s most impressive remains are the royal tombs and their fabulous markers, the ‘stelae’ or obelisks. Even the plain examples are impressive, reduce from challenging neighborhood granite.

But truly staggering is a series of six carved examples. These look to depict the dead rulers’ palaces—their tombs lay beneath, and it was our good fortune to be the discoverers of this underground world. The stelae—or so we could conjecture—had been the stairways to heaven for the kings of Aksum. At the base are granite plates with carved wine-cups for offerings to the spirit of the deceased.

The biggest stela is undoubtedly amongst the largest single stones ever quarried by human labour. It testifies to the magnificent self-esteem of the unknown ruler who had it extracted and dragged several kilometres to its final web site, and to the talent and artistry of these who ready and decorated it.

More than thirty-3 metres tall, the stele represents a thirteen storey tower, with elaborate window-tracery, frames, lintels, beam-ends, even a door with a bolt. This monstrous stone quickly fell—maybe a couple of seconds after being levered upright—smashing onto the roof block of a tomb nearby.

This block (some 17 x 7 x 1.5 metres), was not broken, although the tomb underneath it was crushed, but the great stele separated into 3 pieces. The top was fully smashed by the impact.

Nearby is its biggest nonetheless-standing neighbour, twenty-seven metres tall.

Underneath this ‘stele field’ is an extraordinary series of tombs, the underground maze which we began in 1973-four to discover and clear.

On all sides tunnels open out—some dug by robbers. The ground right here contains fallen stelae, or their base-plates, that have slipped down from above, buried staircases, walls and walled platforms, shafts and other structures, as nicely as tomb chambers and their contents—skulls and bones, pottery, metal, and piles of other grave-goods.

African Bazaar

To celebrate African families working with the organisation both overseas and in Ireland, Trócaire invites visitors to ‘Africa Day @ Iveagh Gardens’ to participate in entertaining jigsaw-generating activities. Trócaire’s space at the event will comprise a big jigsaw, made up of 11 pictures of different households, which includes:

* The families of African people who perform in the organisation’s overseas offices and their offices in Maynooth, Belfast and Cork.
* The families of Trócaire’s partners overseas.
* The households of folks their partners function with on the ground.

Visitors to the occasion will be invited to try their hand at placing this giant jigsaw collectively. Blank mini-jigsaws will also be offered, on which young visitors can draw their own families and – afterwards – bring their newly-designed jigsaws residence.

Stands detailing the stories of four of the families featured in the giant jigsaw – and their connection with Trócaire – will also be displayed.

Obama’s New Space Frontier

Image by jurvetson
From Cape Canaveral yesterday, President Obama toured the SpaceX facilities with Falcon 9 erect on the pad, and then joined Buzz Aldrin and Elon Musk to present a new vision for NASA.

Elon Musk summarizes: “Today, the President will articulate an ambitious and exciting new strategy that will alter our destiny as a species. I believe this address could be as critical as President Kennedy’s 1962 speech at Rice University. For the initial time because Apollo, our country will have a plan for space exploration that inspires and excites all who appear to the stars. Even much more essential, it will work.”

Here is the complete text of President Obama’s speech and some excerpts:

“Few folks — present organization excluded — can claim the experience of Buzz and Bill and Charlie when it comes to space exploration. I have to say that handful of men and women are as singularly unimpressed by Air Force One particular as these 3. (Laughter.) Confident, it is comfortable, but it can’t even reach low Earth orbit. And that naturally is in striking contrast to the Falcon 9 rocket we just saw on the launch pad, which will be tested for the very 1st time in the coming weeks.

The space race inspired a generation of scientists and innovators, which includes, I’m positive, numerous of you. It’s contributed to immeasurable technological advances that have improved our wellness and properly-being, from satellite navigation to water purification, from aerospace manufacturing to health-related imaging. Even though, I have to say, throughout a meeting right ahead of I came out on stage somebody mentioned, you know, it is a lot more than just Tang — and I had to point out I truly really like Tang. (Laughter.)

For me, the space plan has always captured an crucial element of what it indicates to be an American — reaching for new heights, stretching beyond what previously did not look achievable. And so, as President, I believe that space exploration is not a luxury, it’s not an afterthought in America’s quest for a brighter future — it is an essential part of that quest.

So these days, I’d like to talk about the next chapter in this story.

Let me begin by becoming really clear: I am one hundred % committed to the mission of NASA and its future. (Applause.) Since broadening our capabilities in space will continue to serve our society in ways that we can scarcely envision. Because exploration will once much more inspire wonder in a new generation — sparking passions and launching careers. And simply because, ultimately, if we fail to press forward in the pursuit of discovery, we are ceding our future and we are ceding that vital element of the American character.

NASA, from the commence, several months ago when I issued my budget, was a single of the places where we didn’t just keep a freeze but we actually increased funding by billion. By undertaking that we will ramp up robotic exploration of the solar system, including a probe of the Sun’s atmosphere new scouting missions to Mars and other destinations and an advanced telescope to stick to Hubble, enabling us to peer deeper into the universe than ever before.

We will improve Earth-primarily based observation to enhance our understanding of our climate and our world — science that will garner tangible rewards, helping us to defend our environment for future generations.

And we will extend the life of the International Space Station likely by far more than 5 years, although in fact making use of it for its intended goal: conducting sophisticated study that can support enhance the day-to-day lives of people right here on Earth, as nicely as testing and improving upon our capabilities in space. This includes technologies like a lot more effective life support systems that will aid decrease the expense of future missions. And in order to reach the space station, we will operate with a growing array of private organizations competing to make acquiring to space easier and far more affordable. (Applause.)

Now, I recognize that some have stated it is unfeasible or unwise to operate with the private sector in this way. I disagree. The truth is, NASA has always relied on private market to help design and develop the vehicles that carry astronauts to space, from the Mercury capsule that carried John Glenn into orbit nearly 50 years ago, to the space shuttle Discovery at the moment orbiting overhead. By purchasing the solutions of space transportation — rather than the automobiles themselves — we can continue to guarantee rigorous safety standards are met. But we will also accelerate the pace of innovations as organizations — from young startups to established leaders — compete to design and develop and launch new indicates of carrying men and women and supplies out of our atmosphere.

Subsequent, we will invest a lot more than billion to conduct analysis on an sophisticated “heavy lift rocket” — a vehicle to effectively send into orbit the crew capsules, propulsion systems, and huge quantities of supplies necessary to reach deep space. In establishing this new car, we will not only appear at revising or modifying older models we want to look at new designs, new supplies, new technologies that will transform not just where we can go but what we can do when we get there. And we will finalize a rocket design no later than 2015 and then start to construct it. (Applause.)

So the point is what we’re searching for is not just to continue on the same path — we want to leap into the future we want major breakthroughs a transformative agenda for NASA. (Applause.)

The bottom line is no one is a lot more committed to manned space flight, to human exploration of space than I am. (Applause.) But we’ve got to do it in a smart way, and we can not just preserve on doing the identical old things that we’ve been carrying out and pondering that somehow is going to get us to exactly where we want to go.

Some have said, for instance, that this plan offers up our leadership in space by failing to produce plans inside NASA to attain low Earth orbit, instead of relying on businesses and other nations. But we will truly reach space more quickly and a lot more often beneath this new plan, in ways that will help us increase our technological capacity and reduce our expenses, which are each essential for the lengthy-term sustainability of space flight. In truth, by means of our strategy, we’ll be sending numerous far more astronauts to space more than the subsequent decade. (Applause.)

There are also these who criticized our decision to end parts of Constellation as one particular that will hinder space exploration beyond low Earth orbit. But it is precisely by investing in groundbreaking study and revolutionary firms that we will have the possible to quickly transform our capabilities — even as we create on the crucial perform already completed, by means of projects like Orion, for future missions. And as opposed to the prior program, we are setting a course with specific and achievable milestones.

Early in the next decade, a set of crewed flights will test and prove the systems required for exploration beyond low Earth orbit. (Applause.) And by 2025, we count on new spacecraft developed for extended journeys to allow us to commence the initial-ever crewed missions beyond the Moon into deep space. (Applause.) So we’ll begin — we’ll start by sending astronauts to an asteroid for the very first time in history. (Applause.) By the mid-2030s, I believe we can send humans to orbit Mars and return them safely to Earth. And a landing on Mars will comply with. And I count on to be about to see it. (Applause.)

But I want to repeat — I want to repeat this: Critical to deep space exploration will be the development of breakthrough propulsion systems and other sophisticated technologies. So I’m challenging NASA to break via these barriers. And we’ll give you the sources to break by way of these barriers. And I know you will, with ingenuity and intensity, because that’s what you have always carried out. (Applause.)

So this is the subsequent chapter that we can create together here at NASA. We will companion with market. We will invest in cutting-edge analysis and technology. We will set far-reaching milestones and provide the sources to reach those milestones. And step by step, we will push the boundaries not only of exactly where we can go but what we can do.

Fifty years right after the creation of NASA, our objective is no longer just a location to attain. Our goal is the capacity for men and women to work and understand and operate and reside safely beyond the Earth for extended periods of time, ultimately in techniques that are much more sustainable and even indefinite. And in fulfilling this task, we will not only extend humanity’s attain in space — we will strengthen America’s leadership right here on Earth.

Now, I’ll close by saying this. I know that some Americans have asked a question that’s particularly apt on Tax Day: Why commit income on NASA at all? Why commit cash solving troubles in space when we don’t lack for issues to solve here on the ground? And certainly our nation is still reeling from the worst financial turmoil we’ve known in generations. We have huge structural deficits that have to be closed in the coming years.

But you and I know this is a false choice. We have to repair our economy. We need to close our deficits. But for pennies on the dollar, the space program has fueled jobs and entire industries. For pennies on the dollar, the space program has enhanced our lives, advanced our society, strengthened our economy, and inspired generations of Americans. And I have no doubt that NASA can continue to fulfill this role. (Applause.) But that is why — but I want to say clearly to those of you who operate for NASA, but to the whole community that has been so supportive of the space system in this area: That is precisely why it’s so vital that we pursue a new course and that we revitalize NASA and its mission — not just with dollars, but with clear aims and a larger goal.

Now, little much more than 40 years ago, astronauts descended the nine-rung ladder of the lunar module referred to as Eagle, and allowed their feet to touch the dusty surface of the Earth’s only Moon. This was the culmination of a daring and perilous gambit — of an endeavor that pushed the boundaries of our understanding, of our technological prowess, of our really capacity as human beings to solve issues. It wasn’t just the greatest achievement in NASA’s history — it was one particular of the greatest achievements in human history.

And the query for us now is whether that was the starting of something or the finish of some thing. I select to think it was only the beginning.”

Boeing’s B-29 Superfortress was the most sophisticated propeller-driven bomber of World War II and the 1st bomber to residence its crew in pressurized compartments. Although designed to fight in the European theater, the B-29 identified its niche on the other side of the globe. In the Pacific, B-29s delivered a assortment of aerial weapons: conventional bombs, incendiary bombs, mines, and two nuclear weapons.

On August six, 1945, this Martin-constructed B-29-45-MO dropped the first atomic weapon utilised in combat on Hiroshima, Japan. Three days later, Bockscar (on display at the U.S. Air Force Museum near Dayton, Ohio) dropped a second atomic bomb on Nagasaki, Japan. Enola Gay flew as the advance weather reconnaissance aircraft that day. A third B-29, The Great Artiste, flew as an observation aircraft on both missions.

Steven F. Udvar-Hazy Center: Kawanishi N1K2-Ja Shiden Kai “George”

Image by Chris Devers
See a lot more images of this, and the Wikipedia write-up.

Details, quoting from Smithsonian National Air and Space Museum: Steven F. Udvar-Hazy | Kawanishi N1K2-Ja Shiden (Violet Lightning) Kai (Modified) &quotGEORGE&quot:

GEORGE is the unlikely Allied nickname for the greatest Japanese naval fighter made in quantity during Globe War II. The official Japanese name and designation was Kawanishi N1K2 Shiden (Violet Lightning). This outstanding land-based fighter sprang straight from a floatplane fighter design and style, the N1K1 REX (see NASM collection).

A lot of countries utilized floatplanes for scouting and reconnaissance duties, and to hunt submarines and surface ships, but only Japan built and fielded fighters on floats. The Japanese Imperial Navy intended to use these specialized aircraft to achieve air superiority above a beachhead to support amphibious landing operations where carrier or land-based fighters have been unavailable. The Kawanishi N1K1 (Allied codename REX) was the only airplane designed particularly for this purpose to fly throughout World War II.

In September 1940, the Japanese Navy issued a specification for floatplane fighters capable of supporting offensive naval operations. A group of engineers like Toshihara Baba, Shizuo Kikuhara, Hiroyuki Inoue, and Elizaburo Adachi had readied the very first prototype by May possibly 1942, and it flew on May possibly 6. Tests showed that the speed of new airplane was only slightly less than the Mitsubishi A6M Zero (see NASM collection) and the amphibious fighter was practically as maneuverable as its land-based cousin. This was exceptional performance for an aircraft that could not retract or jettison its enormous landing gear.

Long just before the initial Kyofu flew, Kawanishi engineers believed that the standard design and style would also make an excellent land-primarily based fighter. The conversion appeared to entail just replacing the primary and wingtip floats with a conventional landing gear. The organization decided to develop this variant as a private venture. As the project unfolded, the engineers decided to replace the 14-cylinder engine with a new 18-cylinder model expected to create about 2,000 horsepower. The new engine required a bigger propeller and this element, in turn, needed abnormally extended landing gear struts to stop the blade suggestions from contacting the ground. Kawanishi flew the initial N1K1-J land-based fighter on December 27, 1942. The new engine failed to deliver the anticipated energy and the landing gear functioned poorly. The airplane also fell brief of projected speed (649 kph – 403 mph) by 74 kph (46 mph) and could handle only 575 kph (357 mph). This was more quickly than the Mitsubishi A6M Zero ZEKE, nonetheless, and the Japanese Navy badly required an efficient counter to new American naval fighter aircraft such as the Grumman F6F Hellcat and Vought F4U Corsair (see NASM collection). The Japanese Navy ordered Kawanishi to abandon two other fighter projects and begin developing Shidens.

By the end of 1943, Kawanishi delivered about 70 of the new fighters and the Navy employed these airplanes for pilot familiarization and instruction. Expecting Allied amphibious landings in the Philippines, the Navy sent the very first Shiden unit to Cebu in time to challenge Allied air power supporting the invasion of that island in October 1944. Engine, landing gear, logistics, and maintenance difficulties plagued the Shiden units but Allied pilots realized they faced a excellent new Japanese fighter.

With N1K1-J production underway and Shidens flying combat missions, Kawanishi set about refining the style. They lowered the wings from mid-fuselage and the further ground clearance permitted the engineers to install a shorter, a lot more traditional and significantly less-troublesome landing gear, simplified the fuselage structure, and redesigned the empennage. Only the wings and armament remained from the initial style. The engine continued to give problems, but the Navy was impressed with these improvements and ordered the new version into production as the N1K2-J Shiden Kai (modified). In air-to-air combat, seasoned Japanese pilots flying Shiden Kais could far more than hold their own against most American pilots flying F6F Hellcats. In February 1945, a brave pilot, Warrant Officer Muto, single-handedly engaged 12 Hellcats and shot down four of them just before the remainder disengaged. Flying intercept missions against Boeing B-29 Superfortresses above the residence islands, the Shiden Kai was much less effective since of inadequate climb speed and power loss at higher altitudes.

Kawanishi created several other variants and planned much more when the war ended. About 1,500 of the different models have been developed. In battle more than Formosa (Taiwan), the Philippines, Okinawa, and the home islands, Shiden pilots acquitted themselves well but this outstanding airplane was another good design and style that appeared also late and in also couple of numbers to reverse Japan’s fortunes in the air war.

NASM’s Shiden Kai is 1 of three remaining right now. The other two are displayed at the U. S. Air Force Museum in Dayton, Ohio, and the New England Air Museum in Windsor Locks, Connecticut. American intelligence units collected 4 GEORGE fighters from a variety of Japanese airfields and delivered them to Yokosuka Naval Shipyard for shipment to the United States. The NASM GEORGE came from Omura or Oppama Naval Air Station, Japan, and the fighter arrived stateside aboard the escort carrier &quotUSS Barnes.&quot It was almost certainly evaluated at the Naval Aircraft Factory at Philadelphia, and then moved to Willow Grove Naval Air Station. The GEORGE remained outdoors on show and steadily deteriorated along with a group of German and Japanese airplanes until 1983 when the Smithsonian Institution acquired it. The airplane was stored at the Paul Garber Facility till NASM loaned it to the Champlin Fighter Museum in Mesa, Arizona, for restoration in December 1991 and the project was completed in November 1994. The restored Shiden Kai wears the colors and markings of the 343rd Kokutai, a unit stationed at Omura Naval Air Station in 1945.

DIY half-frame cam

Image by bricolage.108
Right after thinking about how i could produce a homemade half -frame camera and seeing a considerably more easier attempt to achive related outcomes, this is what i came up with.

1st i modified the camera so i could do double or several exposures. Created this by dismanteling the camera and discovering where the cocking mechanism was. Then i tied a string to the that mechanism so it was feasible to re-cock the shutter by pulling it from outside the camera.

Following that i pierced 3 holes in the plastic to generate an axis for the banner that will block off the selected half the frame. Unless you got a Dremmel or somekind of rotary tool this takes some pacience. I used a tiny precision screwdriver and hold pushing and turning it until the hole was opened.

Then unfolded a massive paper clip till it created a 90º angle and stick it via the holes. Prior to that i’ve cuted a piece of thin cardboard (from a cereal box) half the size of the camera’s inside 35mm plastic mask. This is really essential simply because it will establish two items:

1. if the cardboard will not fall inside the camera hole. Typically that hole is in a angle so you have some room for error, but not considerably.

two. the space among the resulting two frames. In my case i produced it to wide so the resulting image has a massive black strip in the middle of the photos. See an example.

Then one more tricky element. You have to pass the tape, already half taped to a single of the sides of the cardboard via the space in between the plastic and the clip, and then taped to the other side.

Ok the primary function is completed now all that is required is to seal the holes to keep away from key light leaks. I glued a piece of sock but i think it is attainable to use other material with identical effect.

To use it: merely pick the best or the bottom frame to be masked using the paper clip, obtaining that in thoughts, shot, then re-cock the shutter pulling the string, pick the other frame and shot. Then advance the film.

Considerations:
It’s crucial to have in thoughts what’s the frame that is becoming masked because there’s no indication in the viewfinder about that. Possibly next time )
An additional thing that i consider it could work is to make, for example, double exposures in just a single frame and not the other or in both.
Also however to try, that may possibly be fascinating is to shot multiple shots with the mask not completly down or up.

You can verify the resulting photos using this cam.
