  1. Earliest known drawing found on rock in South African cave Archaeologists found the marked stone fragment as they sifted through spear points and other material excavated at Blombos cave in South Africa. It has taken seven years of tests to conclude that a human made the lines with an ochre crayon 73,000 years ago. Not much to go on. The size of a couple of fingernails, possibly a chunk broken off something bigger. The facts that it was human made, and 73,000+ years old stand out the most.
  2. You wouldn't know how to notice it. Sneaking is one art they're expert at.
  3. Replaced it with a quote from Howard Roark, rather than Ellsworth Toohey: I've always demanded a certain quality in the people I liked. I've always recognized it at once --- and it's the only quality I respect in men. I chose my friends by that. Now I know what it is. A self-sufficient ego. Nothing else matters.

    Biologists Replicate Key Evolutionary Step

    Scientists identify protein that may have existed when life began The primordial peptide may have appeared 4 billion years ago Date: August 30, 2018 Source: Rutgers University Summary: How did life arise on Earth? Researchers have found among the first and perhaps only hard evidence that simple protein catalysts -- essential for cells, the building blocks of life, to function -- may have existed when life began. Researchers have designed a synthetic small protein that wraps around a metal core composed of iron and sulfur. This protein can be repeatedly charged and discharged, allowing it to shuttle electrons within a cell. Such peptides may have existed at the dawn of life, moving electrons in early metabolic cycles. Credit: Vikas Nanda/Rutgers University-New Brunswick Hard Evidence? The scientists used computers to model a short, 12-amino acid protein and tested it in the laboratory. This peptide has several impressive and important features. It contains only two types of amino acids (rather than the estimated 20 amino acids that synthesize millions of different proteins needed for specific body functions), it is very short and it could have emerged spontaneously on the early Earth in the right conditions. The metal cluster at the core of this peptide resembles the structure and chemistry of iron-sulfur minerals that were abundant in early Earth oceans. The peptide can also charge and discharge electrons repeatedly without falling apart, according to Nanda, a resident faculty member at the Center for Advanced Technology and Medicine. "Modern proteins called ferredoxins do this, shuttling electrons around the cell to promote metabolism," said senior author Professor Paul G. Falkowski, who leads Rutgers' Environmental Biophysics and Molecular Ecology Laboratory. "A primordial peptide like the one we studied may have served a similar function in the origins of life."

    Is a cashless society on the cards?

    Jack Ma enters the fray with a certain sense of irony. The Chinese government is finding a private citizens entry into the financial fray disruptive. An excerpt from Jack Ma’s Giant Financial Startup Is Shaking the Chinese Banking System: Ant Financial Services Group, founded by Chinese billionaire Jack Ma, has become the world’s biggest financial-technology firm, driving innovations that let people use their phones for buying insurance as easily as groceries, enabling millions to go weeks at a time without using physical cash. That success is also putting a target on the company’s back. China, even more than the U.S., is now under pressure to reckon with the disruptive power of a financial-technology giant.

    It was a musing on "I can not refind it, does that tell you something?" "The Crow" is why I have to listen to multiple recordings over again to try finding something again. I generally don't remember everything I've ever heard and where, specifically, I've heard it. In this case, I don't have the book, you mentioned. The lecture it came from happens to be available on the ARI site.

    32:30<--->37:30, both the question asked & the answer given (as relates to this thread). It informs me that 'the crow' is real.

    Fallacy of Logical Omniscience

    If you picked up a log from a fire that was glowing with red embers for its entire length and circumference with your bare hands, I would expect the yell that followed to be loud. In order for concepts to be objective, two things must be present. The object of consciousness and the consciousness of the object. By moving closer to the fire, I can become aware of the heat radiating from it. The conceptual identification that it is hot converts a fact into a perceptual 'device' that can communicate to you, and be held conceptually by me, even after leaving the vicinity of the fire. The sensations only last for their respective durations.

  12. The Dispilio Tablet - the oldest known written text The tablet has been dated from the 5000 BC era. Depending on the merit of this assessment: Dispilio tablet deciphered – a proof of the oldest script in the world? the alphabet appears to be a mix of the Phoenician and the Glagolitic alphabets with a mention of a disputed Vinča symbols.

    Biologists Replicate Key Evolutionary Step

    In the beginning was the phase separation A simple mechanism could have been decisive for the development of life Date: May 23, 2018 Source: Technical University of Munich (TUM) Summary: The question of the origin of life remains one of the oldest unanswered scientific questions. A team has now shown for the first time that phase separation is an extremely efficient way of controlling the selection of chemical building blocks and providing advantages to certain molecules. Molecules in the garage The effect can also be seen externally: the initially clear solution becomes milky. The lack of water in the oil droplets is like a protection because anhydrides need water to disintegrate back into carboxylic acids. [Chemist Job] Boekhoven explains the principle of phase separation with an analogy: "Imagine an old and rusty car: Leave it outside in the rain, and it continues to rust and decomposes because rusting is accelerated by water. Put it in the garage, and it stops rusting because you separate it from the rain." In a way, a similar process occurs in the primordial soup experiment: Inside the oil droplet (garage) with the long-chain anhydride molecules there is no water, so its molecules survive longer. If the molecules compete with each other for energy, again those that can protect themselves by forming oil droplets are likelier to survive, while their competitors get hydrolyzed.
  15. This is from the first night of the '76 lecture series: There are various areas of human endeavor where under certain circumstances it’s practical to accept the advice of an expert, and declare: "he knows best—this is not my field". But you cannot do it in philosophy. And this is so even if you found a certified, completely rational expert. It would be useless, for instance, to turn even to such an expert and say to him, I need a philosophy, you’re an expert, so I’m asking you, should I for instance be selfish? Just tell me, yes or no, so I can act. I haven’t time for discussion and proofs, just give me answer. Now that expert could just say, well that’s easy, just be selfish, and then leave the room, but would that do you any good? After all he told you the truth, but what else would you need? Now, just in pattern, just to give you a taste of what would be involved, just one example. You’d need to know what selfishness is. That would be very helpful. And how do you apply such a wide abstraction in particular in real life situations? And to be selfish, does that mean do whatever you feel? If so, what do you do if your feelings are irrational and clash with other people, and how do you know what’s rational anyway? And who can say how another man should live? Maybe what’s true for the expert, isn’t true for you. Or is truth objective, or what is truth? What is objectivity? And what’s the use? How do you know if you can achieve your goals in this kind of a world, so is there any point to being selfish, or what kind of world is it anyway? And if everyone was selfish, wouldn’t that mean cut-throat competition, and dog-eat-dog, and child labor? And how do you know the answer to all these questions, by what method of knowledge, etc. Now that’s just a taste, a sample of the pattern. The point is you need to know it all—the whole system, not on faith. Faith doesn’t work. It’s useless, even if what you have faith in happens to be true. You need to know it all firsthand with objective proof of each point on strictly practical grounds, to make use of it, to function, to live. In answer to the question: Does one have to create one's own philosophy?, the answer is no. Without validation, however, it is useless.
