Scientists explain ancient Rome’s long-lasting concrete

archaeologicalnews:

Researchers have unlocked the chemistry of Roman concrete which has resisted the elements for thousands of years.

Ancient sea walls built by the Romans used a concrete made from lime and volcanic ash to bind with rocks.

Now scientists have discovered that elements within the volcanic material reacted with sea water to strengthen the construction.

They believe the discovery could lead to more environmentally friendly building materials.

Unlike the modern concrete mixture which erodes over time, the Roman substance has long puzzled researchers.

Rather than eroding, particularly in the presence of sea water, the material seems to gain strength from the exposure. Read more.

OH. Oh oh oh. 

I think I’ll start using the title “Anaškad” for Sauron as the godking of Mordor and Harad. Possibly Ar-Anaškad–  which would become, approximately, “Ring Lord”. Eh? Eh? :DD

You see a lot where the Feanorians all inherited bits of their dad, and I love that. They’re all angry nerds, but I mean specifically. Maedhros has the Charisma. Maglor got the artistry, the thing for aesthetic. Caranthir got the pedant thing. Will also fight you in a Waffle House at 3am. The Ambarussa are insatiably curious. Curufin…exists. But! You also see a lot where Celegorm Does Not Have This. Which makes sense, because he’s a muddy, bloody fukboi, but!! I raise you!!! The languages!! Granted, not linguistics proper, there wouldn’t be an essay written about him and his Thing about digraphs, but languages! ‘All the tongues of birds and beasts he knew.’ He likes to communicate. He’s the kid who travels after high school and comes back semi-fluent in more than one language, because he kept accosting people in pubs like hey, what are we doing, what are we saying. Also! Fighting styles. Less apparent, because Feanor only started fighting things like a week before combusting, but their fite-moods are similar–i.e, real fuckin fell and fey. Someone should really kill them–not you, you’re running, but someone should get on that.

Everything about this is perfect

Persian Astrolab

This early Persian astrolabe with a geared calendar movement is the oldest geared machine in existence in a complete state. It illustrates an important stage in the development of the various complex astronomical machines from which the mechanical clock derives.
Islamic scholars learned of this design from a text by one of the greatest Islamic scientists, al-Bîrûnî (973-1048), who explained how gearing might be used to show the revolutions of the sun and moon at their relative rates, and to demonstrate the changing phase of the moon. These phenomena were of fundamental importance in the lunar calendar used in Islam.

‘ If I wish I may? ‘ there was a smile on her lips, though her hands were already exploring to say, at last. His chest was a fine one, a bit hairy, of course, though she seemed not to mind as she stroked down his muscles, quietly purring at that. ‘ What are you doing tonight again? ‘

“Be bold, my lady, but not too bold,” he rumbled, taking her hand gently from his chest and kissing it. “I have many charges to tend to, both here and far off. You would do better by far to serve me as a lord, and not a consort– delighted though I am by your favor.”
