Trajan attacked the Daci after major gold deposits were found there. Wiped out the whole population (yes, a real genocide) in order to re-settle the land with more docile people, and harvested the gold.
If you don't believe this, please consider that the Osman empire used the most modern cannons in the successful siege of Constantinople, and then in 1529 in the less successful siege of Vienna. The gun knowledge was picked up by Austrian gunmakers, which in turn brought it to England. The English guns were further improved, but basically were the result of Turkish work.
The Spanish guns couldn't match this for the simple reason that their balls were mass-produced quickly, and to speed up the cooling in the foundry, they were dumped in water. This made the iron very brittle, and most cannonballs simply broke apart when fired. Thus, the Spanish effectively fired shrapnel, which doesn't travel very far and could not harm the English ships at usual fighting distances.
As the article carefully states, even Arboform uses only 50% lignin (yes, I *did* RTFA). The rest is made up of rather expensive "additives" - one crucial ingredient being Ecoflex, a synthetic (= oil-based) polymer which is needed to reduce the extreme brittleness of genuine lignin.
Two hopes spelled out in the articles will never materialize: - it will never be as cheap as oil-based plastics are today, and - it will never be able to replace most of the current oil-based plastics due to it's poor mechanical properties (unless we reduce the lignin content even further).
Cellophane is only one of many cellulose-derived plastics. Celluloid was the first, but the most important are esters of cellulose and organic acids. Cellulose acetate was first produced in 1865, and others are cellulose butyrate and cellulose propionate. Unfortunately, although produced on an industrial scale for a long time, they are much more expensive than most plastics.
Actually, Lockheed and Boeing competed for a giant military transport aircraft in the Sixties, and Lockheed won. Their plane became the C-5, and Boeing made the best use they could of their government-sponsored, losing design: They turned it into a commercial airliner. The upper deck was designed to get a tank loaded through the front doors and still have the cockpit at a reasonable place in the airframe. The front doors were left out, eventually, but the outer shape was kept. Boeing still spent a lot of their own money on the 747, but it got started on government money.
It's really quite obvious. Look how many stages a rocket needs to lift any meaningful payload into orbit. This thing is just a Lear Jet with a rocket. Not only it is a single-stage vehicle, it also has to lift the wings and engines all the way into "orbit" and back.
If they keep the payload down and load it up with rocket fuel, it may fly a parabola with the top at 50 or 80 km. Not more, at least not before it has been heavily modified.
Sorry to make this look less spectacular - but Greenpeace is just serving its audience what they want to hear. If they would't do it, someone else would fill the gap.
What really is to lament is our press and influential people (politicians, Hollywood stars - you name it) being so attracted to sensations and uncritical of simple stupidity. They have - a least in my eyes - a moral responsibility to stick to truth and logic. Instead, they go the easy road of political correctness and pandering to the masses. But where should those masses improve their knowledge and reasoning if not by example of those who determine what can be read and heard?
We have a lot of growing up to do - even 300 years after the enlightenment started, much of the world is left in darkness!

The American space age could already be at 52, you know.
I wonder why nobody has pointed out that Explorer could have been launched late in 1956, were it not for the vanity of the US Navy, who insisted that the first US space rocket should be an all-American affair (Vanguard). The Juno rocket had been developed by the US Army with the help of von Braun and his Peenemünde team in 1955-56, and was sitting for over a year in storage until after the Sputnik shock and failed Vanguard launches.
What about this: Make all copying legal. The only source of income for artists will then be through life performance. Just like in the old days! This model supported a vibrant, hugely creative culture then, why should it not continue to work? The current model only distorts the rewards in favor of the top-rated performers. They earn money totally out of proportion to their work, and most other artists of similar quality (but less luck) lose out. The intermediaries who cream off most of the revenue will no longer be needed. No more labels, and all our money will directly and fully benefit the artists. Sounds too simple? Again, this has worked for centuries!
Theoretically they will make sharper turns, but this will need a strengthened structure, a much larger wing to create the necessary lift forces, and most of all, a much bigger engine. In normal operation, these wings and engines are ridiculously inefficient, though, and will cut the range and endurance roughly by half. Also, since the air-to-air missiles take much less time to develop than airplanes, this advantage will only last a few years, after which you will be stuck with an inefficient and ineffective UCAV.

Why are suffixes so enduring?
Because the human using the computer wants a quick way to determine what the file most likely contains.
That's exactly what icons are for. Suffixes belong to command line based systems, and MS should have deleted them 20 years ago.

Or was it just a coincidence?
The first modern cannons were Turkish.

I'm surprised nobody pointed this out so far!

That's only part of the truth!
