  1. my physics teacher's theory about little demons explaining friction was very simple and explained an awful lot. my favourite bit was that a car's tyres squeal when it stops suddenly because you've trampled hundreds of little demons to death.

  2. Please make lots more videos about ancient Greece and Rome! I love them!!

  3. One thing that surprised me about Greek mythology is that the myths were set in roughly the same era. For example, Hercules joined Jason on his expedition. This was because they looked back to the Mycenaean era at its height as a golden age.

  4. My dad's radio could pick up short-wave frequencies. In the early 70s there were lots of stations, although they declined over the decade. Even then there were these frequencies that would send a continuous buzz where sometimes a voice could also be heard. My dad's theory was that the voice was a broadcast and the buzz was a foreign authority deliberately blocking the broadcast by rendering it inaudible.

  7. Life evolved to create its own energy!? We'd have to rewrite every science textbook if that happened. Have you ever heard of thermodynamics?

  9. Von Neumann calculated that relative to Einstein, Heisenberg's position was uncertain while Bohr was on another level.

  10. We used harnesses with our kids. the main difference was that it distributed the force along two collar bones and away from the neck altogether. I get motion sick if I sit facing backwards. i suspect that's not a solution for some people.

  11. in my state it's a gradual taking on of rights and responsibilities. examples: 14 can see a doctor without guardian 15 can leave school early to start work (but recommended you do finish school) 16 learn to drive, have sex (age limit on older partner until 18) 17 drive 18 alcohol, vote, sign legal documents (legally an adult) but some things come in after 18 21 earn adult pay some legal contracts require people to be 21 or 25 to ensure sufficient maturity common in wills for beneficiary to be 25 before they can access inheritance

  12. what is he referring to? i've never heard of birds using fire anywhere let alone in australia.

  13.  @thefourshowflip  IIRC it was offered as a silly example of an ad hoc theory where you would have to keep adding more and more embellishments to make it explain more and more phenomena related to friction such as roughness, heat, noise and so on.

  14. their problem was that if a man was attracted to men, the penetrated man would end up being a social outcast. the workaround was to make the penetrated partner a boy. that way he wouldn't have adult social status to lose. society imposed safeguards: it was voluntary; the boy had to be old enough; in exchange the "beloved" would receive an education from his "lover"; most important to the boy's welfare the relationship had to end by the time he reached adulthood. unacceptable by modern standards for sure. i wonder if anyone has been able to study how much harm it did. but what else could they do given the constraints of their culture?

  15. Allan Bromley did his research in the 1980s, not "the early 1900s". He was one of my university professors here in Australia. I helped translate a letter he received from Greece about his itinerary there.

  17. yes i think that's the most practical way of classifying them. but that raises a question. do we consider seeds and spores "alive"? i planted a lentil and watched it grow into a plant, but the lentil itself does not utilize environmental energy or replicate itself while siting in a packet on the shelf.

  18.  @apollo1573  planets are not closed, isolated systems. material does get ejected from one and lands on another. dozens of meteorites on earth have been of martian origin, and they're just the ones we know about. probably the reverse has happened as well. a living organism is unlikely to survive the impact of being ejected, the airless interplanetary flight and the gruelling heat of entry. however, it's theoretically possible that a chemical that spawned life could survive and travel from one world to another. an alternative idea is that chemicals that spawned life could have originated in places like comets. as both planets could realistically pass through the same or similar comet's tail, the same life-spawning chemical could have contaminated both planets. carbon-based compounds like methane occur naturally in such bodies.

  20. someone I know had ECT because they weren't responding to other treatments. it worked, but they experienced some memory loss, some temporary but some permanent. the recovery wasn't permanent either, but at least relapses have been less severe.

  24.  @sorandkairi00  same, 50 years ago in high school. at the time they were classified as a kingdom in the tree of life, but it was noted that there was disagreement as to whether they were actually alive.

  27. My son was asked to mind a cat while his owner went overseas, but when he decided to stay there, he gave the pet to us (my son already had two cats). This cat follows me around, sleeps on my bed at night, sits on my desk with me, and I've never felt closer to an animal in my life.

  28.  @kaltaron1284  Modern use of katakana is primarily for foreign words but also for some native terms such as onomatopoeia. IIRC they originally both developed independently for the same purpose, to represent phonetic sounds notably inflected word endings. Originally these were written in selected kanji used for phonetic value but was confusing as they were mixed in with kanji used for semantic value. Hiragana was developed by aristocratic women by writing phonetic use kanji in cursive script while Buddhist monks developed katakana by simplifying phonetic use kanji. In modern times, there were official reforms to standardize kana usage. The last reform was in 1946 although oddities still remain. I haven't encountered any major regional differences but you'd have to ask someone more knowledgeable. I've heard of hentaigana, alternative competing kana for some phonetic values that fell into disuse, but their usage is rare.

  29. I went to primary school in the 60s in Australia and we learnt very little negative about the british empire. we just did the magna carta and british settlement in australia but nothing of the disastrous impacts on existing inhabitants here. History was an elective in high school which I didn't choose.

  32. so the answer is, somewhere between 1000000 and 150000 years ago. That pins it down.

  34.  @apollo1573  it would be a common origin if some particular chemical has a likelihood of steering life in a certain direction. it would evolve in different directions, but could have some commonality due to the same underlying cause. like you find radically different life in isolated environments on earth utilizing different energy sources, but it's possible they shared a common ancestry in some kind of chemical reaction that seeded it. personally i think that life on two planets having a common origin is highly speculative. we have no idea what reactions caused life to start on earth, what could cause life on other worlds, and whether the same reactions that worked on one planet would work on another even if they did have the same origin.

  35.  @apollo1573  i think so too.

  39. The reason Spartans were subjected to such rigorous training was that a Helot uprising could happen any time and the ruling class had to be ready for battle at a moment's notice. Marriage suffered the same constraints as theft. Young men were assigned a wife by the state, but officially there were not allowed to live with her until after their training had been completed. In the intervening years, they had to learn how to sneak out of barracks at night to spend time with their wife and be back before they were noticed gone. If they were caught, they would be punished. There was a also class of people among them who failed the harsh training. I can't remember what I learned about them, but obviously they had no citizen rights.

  40.  @BAValliere  while I share your pain (he's damaged Greek names too) mispronouncing Dutch is understandable given he's English. What's not understandable is his pronunciation of the English word wallaby.

  46. i have one forged postage stamp in my stamp collection. it's nigerian. i received it on one of these scam letters. to reduce their overheads, what they did was photocopy a pane of stamps and drill holes in them with a sewing machine to make the perforations. you might wonder how the nigerian post could be so clueless as to accept hundreds if not thousands letters with forged stamps on them (more on this below). i read an article about it in a stamp magazine. according to the article, this scammer would convince a person to fly to nigeria to meet the scammer in person so as to receive their share of the loot. in reality, what happened would be that the victim would be mugged and robbed of whatever they had in their possession. i read a blog where someone managed to scam the scammer and ended up taking a photograph of their face, which they say they sent to the police. would the police take any action? he suspected that the police would not take any action, just as the post office let the letters with forged stamps through. the reason was that the country was gaining so much wealth through these scams that it would be counterproductive for them to stop them.
