Ancient Ethiopian traders and mathematicians used a doubling-and-halving method of multiplication that effectively decomposed numbers into powers of two—an approach mathematically equivalent to the binary logic that underpins modern day computer processors.

Christians were overwhelmingly responsible for the physical copying and transmission of ancient Greek literature into codex manuscripts that survived to the modern era and only 1% of the ancient pagan literature survived... Catherine Nixey, author of The Darkening Age explains

Fun fact: If the number of Irish Allied troops comprised a single army (c. 200,000), it would have been larger or of equivalent size to two Allied powers (Norway, and New Zealand respectively) The idea that Ireland was pro-Nazi is an ahistorical delusion.

What if ancient builders weren’t just mystics… but mathematicians of frequency? Numbers like 432, 7920, even the pattern of 9-6-3—these show up in ancient measurements and sacred geometry worldwide. Apply the right frequencies, and materials organize themselves into toroidal shapes. Coincidence? Or reverse-engineered knowledge from a lost science? We’re only just beginning to decode what they already knew.

It's deeply disturbing to see the Ethiopian gov't acting more like an occupying foreign force, than the gov't of the people. ESAT NEWS & Local Media from Addis Ababa are reporting that the Ethiopian Gov't is shutting down businesses that sell "#Adwa Victory Day" (Ethiopian Freedom Day) memorabilia and arresting the owners. Imagine if the United States gov't was to shut down businesses that sell "4th of July" memorabilia! Ethiopian Human Rights Commission (EHRC) - ኢሰመኮ Ethiopia Human Rights Council

In the 70s, the Soviet Union heavily promoted the theory that Ashkenazi Jews were descended from the Khazar Empire, an ancient kingdom that converted to Judaism and immigrated to Europe. The claim was weaponized as part of a broader campaign to disconnect modern Jews from any historical connection to the land of Israel. Tucker Carlson’s suggestion that Jews undergo DNA tests captures the essence of what he has become. Parroting conspiracy theories and recycled talking points long exploited by hostile foreign powers to sow division and disruption in the West.

Mati Staniszewski on why ElevenLabs is betting on a cascaded approach for voice agents: “Our approach, as you think about voice agents, conversational agents, is effectively a cascaded approach. You use transcription or speech-to-text, an LLM, text-to-speech, and orchestrate all of that together. Then you have speech-to-speech, which goes directly from speech, and there’s a speech response on the other side. Today, we are optimizing heavily on a cascaded approach. As we work with a lot of the businesses and enterprises, they will need that visibility into what happens. They will want to execute certain tasks on top of that. They want good visibility into each of the steps and great accuracy of all the models. But beyond that, they can abstract away what’s the LLM layer, what’s the intelligence layer, and the integrations are easier in that system. That’s where we are betting a lot of the research work on how you can make that great, and we think we can make that great.” John Collison Mati Staniszewski ElevenLabs

The science behind the incredible 'Acoustics' of ancient amphitheaters : Ancient amphitheaters have long been used as venues for large concerts and events, but how did ancient architects achieve such superb acoustics without today's modern audio equipment and acoustical treatment? In last few decades have seen modern acoustic science employ acoustic simulation software and sophisticated computer models of such open amphitheaters, even though these spaces are known solely from archaeological records and hence virtually reconstructed as acoustic models. Often such computer models are complemented by in situ measurements in some well-preserved ancient theaters using more flexible portable equipment. Recent measurements with audience present show that such near-perfect intelligibility is retained beside increased sound absorption by audience, provided that background noise levels are not excessive. Natural phenomena that made acoustics of ancient amphitheaters so remarkable were a result of simple principles like geometry and use of materials and location made an impact. Engineering and architecture used in these sites enabled sound to propagate through large distances, with clarity, as though one was located just next to the speaker. Amplifying acoustic instruments has been of interest for musicians for centuries, leading to different techniques used at smaller venues and more intimate settings. However, there is something unique about atmosphere created when standing inside an amphitheater from reverberation and resonance that can be heard to witnessing energy expand around you - it's an experience that cannot be replicated elsewhere. So how have ancient technical developments paved way for modern audio technology today in amplification, absorption, diffusion and even 3D soundscapes? Sound travels through air as waves and can be amplified or dampened depending on environment. When sound waves hit a hard surface, like a wall or floor, they bounce back and create echoes. This is what causes reverberation and amplification in large open spaces like amphitheaters. Building design played a crucial role in acoustics of ancient amphitheaters. Curved shape of amphitheater created a natural echo chamber that amplified sounds. Seats were also designed at different heights and distances from stage to create a wave of sound that could be heard at every level of auditorium. Additionally, use of marble and other hard materials throughout structure helped to reflect sound waves. While reflection was important for amplifying sound, too much echo could make it difficult to understand speech or music. For this reason, ancient architects used sound-absorbent materials like curtains, carpets and drapes to absorb excess echoes. Orientation of an amphitheater was also crucial to its acoustics. Venues were often built facing east to west so that performers were bathed in natural light during afternoon. This also helped to create an ideal environment for acoustics, as sound waves would travel in same direction as light. Additionally, orientation of stage and seating areas played a role in creating ideal acoustics. While we can appreciate ingenuity of ancient architects, modern technology has allowed us to understand acoustics of ancient amphitheaters in greater detail. Studies have shown that shape of amphitheater was responsible for up to 50% of its acoustics, with rest being attributed to reverberation, reflection and absorption. We can now understand how ancient venues would have sounded in their prime using computer simulations. Natural phenomena that made acoustics of ancient amphitheaters so remarkable were a result of simple principles like geometry and use of certain materials. Engineers of ancient times unknowingly developed best acoustic structures that are still admired today. 🎥 : A 2nd Century AD, Roman Theater in Calama (Numidia), Algeria 🇩🇿.

Matt Shakman on the Practical Effects in #TheFantasticFour: "we wanted it to feel like it was made in the 60s to a degree, obviously we used a lot of modern technology, we'd be silly not to. But we built miniatures, a giant Galactus outfit, huge practical sets, practical H.E.R.B.I.E, practical FantastiCar. We did everything we could to ground it, we used vintage lenses, we tried to approach things optically. Sue's storm's powers is an optical effect that you could've done in the 60s that we used video projectors and things to create." (Via: IMAX)

Ilya Sutskever predicts that in the coming years—whether it’s three, five, or ten—AI will be able to do everything humans can do. He argues that since the brain is a biological computer, a digital computer should, in theory, be capable of learning and performing all the same tasks. This belief underpins his confidence in the arrival of truly general AI.

Divide the lintel circle at Stonehenge into 30 parts and each spans 10.56 feet. Halve that and a unit emerges: 5.28 feet — the human pace. Count 1,000 of those paces and the result is a mile. This suggests the mile may not be a modern invention at all, but a legacy of an ancient system of measurement encoded in megalithic design.
