 Dead Internet Theory is True

Of the platforms where we know flesh and blood humans do spend enough time, 92% of all content is created by 10% of all users, and engagement with different posts can vary from 0.03% to 0.1% of all viewers. In other words, of the 52.6% of internet traffic which is human-driven, about 9 in 10 users stuck to messaging friends and family and just passively consume contents mostly meant to sell them stuff, or see if they would be interested in propaganda campaigns ran by governments, both theirs ...

 Developing Child's Understanding of Games

During the first stage, beginning around age 5, the child does not yet understand there are fixed rules to the game. Children of this age will play Marbles in an improvisational way, possessing a vague notion of rules but not yet understanding the idea of fixed rules. In the second stage, around ages 8 to 10, the child comes to know that there are rules, and will regard these rules with a near religious reverence. The rules are felt to have their own implicit authority, which cannot be quest...

 Measuring Progress by the Cost of Light

Time is not the only life-enriching resource granted to us by technology. Another is light. Light is so empowering that it serves as the metaphor of choice for a superior intellectual and spiritual state: enlightenment. In the natural world we are plunged into darkness for half of our existence, but human-made light allows us to take back the night for reading, moving about, seeing people’s faces, and otherwise engaging with our surroundings. The economist William Nordhaus has cited the plu...

 Health Concerns Spark Adult Interest in Science

Beginning in middle age and continuing through later adulthood, individuals are often motivated by events in their own lives or the lives of significant others to obtain health-related information.^^ Health-related concerns draw many adults into a new domain of science learning. At the same time, with retirement, older adults have more time to devote to personal interests. Their science learnmg addresses long-standing scientific interests as well as new areas of interest.^^ Adults differ fr...

 Roman Arithmetic

...basic Roman arithmetic is largely rather simple, even for those of us spoiled by Arabic notation. Addition is no sweat, because complex Roman numbers already use what math pros call additive notation, with numerals set beside one another to create a larger number. VI is just V plus I, after all. To add large numbers, simply pile all the letters together, arrange them in descending order, and there’s your sum. CLXVI plus CLXVI? CCLLXXVVII, or CCCXXXII. And one of the advantages of the Rom...

 History of the Concept of Art

Nowadays when someone speaks of "art" you probably think first of "fine arts" such as painting and sculpture, but before the twentieth century the word was generally used in quite a different sense. Since this older meaning of "art" still survives in many idioms, especially when we are contrasting art with science, I would like to spend the next few minutes talking about art in its classical sense. In medieval times, the first universities were established to teach the seven so-called "liber...

 Physical and Actuarial Escape Velocities

The escape velocity cusp is closer than you might guess. Since we are already so long lived, even a 30% increase in healthy life span will give the first beneficiaries of rejuvenation therapies another 20 years—an eternity in science—to benefit from second-generation therapies that would give another 30%, and so on ad infinitum. Thus, if first-generation rejuvenation therapies were universally available and this progress in developing rejuvenation therapy could be indefinitely maintained,...
