  1. Dear All, I am going to take a hiatus from the forum from today. As some of you might know, the natural sciences are not my only area of interest; in particular, I am committed to a form of spiritual practice as well, and have been living in a Buddhist monastery as a lay person for the past few years. I have made the decision to deepen this practice further by ordaining as a monk in the Theravadin Thai Forest tradition, and for various logistical and monastic-political reasons this should ideally happen at a traditional training monastery in Thailand. So tomorrow I will be departing for T

  5. Unfortunately, those of us in the US weren’t able to dismiss him out of hand. And yet his administration’s response seems to not have much to do with the information he got, since he largely ignored it and did almost nothing. Which is one reason I want to know why it would have mattered knowing the details of how the virus originally spread. Would Trump have done a different kind of nothing? Would governors have changed their push to repeatedly reopen too soon? Would they have done something different in avoiding mask mandates? How were these decisions based on the WHO's investigation?

  7. The period over which tidal locking would occur is highly sensitive to the distance between the bodies, and varies by the distance to the power of 6. It is less dependent on the mass of the primary. The relationship ( assuming all else is equal) is T = a^6/M^2 So, if we take a very luminous red dwarf like Lacaille 8760 with a mass of 0.6 that of the Sun, and a Earth equivalent position in the habitable zone of 0.268AU, you get a time period for tidal locking of roughly 1/1000 of the the time it would take for the Earth to tidal lock to the Sun. For a smaller star like Proxima Cen

  8. OK so here is some more Chemistry which I hope will also be useful to Oneworld. As I have mentioned before, homegeny depends upon the scale you are working at. So starting inside the atom things are definitely not homogenous. There is a massive nucleus surrounded by a lot of empty space containing some electrons. Uniformity is represented by saying that every atom of a particular type is the same as every other atom of that type. For example all hydrogen atoms are the same. (for those who know about isotopes I am ignoring them) If we use those atoms to build molecul

You kill animals simply by breathing, ever hear of fairy flies? BTW, feel free to comment in any topic I make, I may not always be right but I at least have the integrity to admit when I'm wrong.

  10. That looks very suspicious... If somebody truly wants to just read the all messages that you posted, you can't do anything with it because in the worst scenario he or she will write crawler/harvester which will visit person profile every couple minutes or seconds (script with wget/curl in a loop), parse it, and check if sonebody wrote anything new and then parse new messages and add to the database. ps.

When I got home, I called the vaccination center for advice and to ask if I should go see a doctor, or be hospitalized. I was told NOT to go to a doctor or a hospital, but just return to the vaccination center immediately and pick up my glasses!!

  16. The thing is, being on twitter, soundbites are kind of necessary, and it's easy to read too much into a tweet where someone is trying to be pithy. Steak-Umm wasn't wrong, but it's arguable what "it" encompasses. The process of science, or the knowledge it uncovers? And are you picking nits when the parenthetical "all science is subject to revision if new information is uncovered" isn't included, because perhaps that was meant to be understood? So yeah, it could have been worded better, but then it wouldn't flow as well. "The good thing about Science is that the truth of the informati

  19. Don't expect too much from me... Ethics never was a main topic for me. I would say, as any sensible person, just the risk of giving capital punishment to an innocent should be reason enough to refrain from it. And AFAIK deterrence seldom works. So I think incarceration might be the best solution, in the first place simply because we put somebody away who has proven to be dangerous, in the second place we, i.e. society must attach consequences to people who do not want to play by the rules. However, if a society does not take the chance to rehabilitate the offender, it is not much us

  20. I think a distinction can be drawn between religion and pseudoscience. Astrology and crystal healing are pseudoscience, in that they make claims about observable physical phenomena, based on theories for which there is no evidence and which conflict with science. Attacking pseudoscience is fair enough, I would say, for anyone with a scientific education. Religion, at least in its more reasonable manifestations, is something different from pseudoscience. It is mainly a guide for living one's life, inspired by stories and ideas that don't make testable physical claims. However one can cer

  23. I'm not a mineralogist, but I can try to add a bit to what others have said, based on what I have quickly been able to read up.😉 Clays are made up of tiny crystals of "clay minerals" and water. The water is hydrogen-bonded to the surface of the crystals, which means it is attached by bonds that are about a tenth the strength of a full "normal" chemical bond. A crystal of dry clay mineral will tend to absorb water until there is a hydrogen bonded film of water all along its surface. Clay minerals are made of sandwiches of sheets of silicate tetrahedra, which have a -ve charge, with m

  24. I quoted only the relevant responses I want to discuss: 1. You say that each profile has its own specific pattern, and then you talk about gene expression and silencing, but that doesn't really answer my question: How did you determine what the boundaries are of 1 profile versus the next, if 2 people have the exact same gene expression except for 1 gene, are they the same profile? If so, at how much deviation do we find ourselves in another profile? How did you determine these boundaries? Have you considered alternatives? 2. So your profiles always match a trait, it never is wrong?

  27. 'Existence' is a word with 9 letters. And if you want to know about the concept behind the word, I think I showed that it depends on the context: existence of what? If you want a general definition you would get something like 'something exists if it can play a role in somebody's life'. And here you see something else: 'existence' is the substantivation of the verb 'to exist'. So the existence of what are you interested in? To give again another example: space and time. One could call them the 'stage' on which causal processes occur (Pity that Markus is away now, he surely had to say some

  28. Nice flamebait attempt. 😁 Speaking as one who is not a "religion fanatic", but was brought up Christian, my understanding is it is so called because Christians believe the sacrifice of Christ on the cross atoned for the collective sins of mankind and made a new contract with God. The word "good" is used in its now obsolete sense of holy.

  29. We don't need the pitches to sound together to sense the harmonic relationship between them. Also, I don't know about you, but I would find music built entirely out of consonant intervals unstimulating to say the least. Good music tells good stories and good stories need some level of conflict. You can't have a Beowulf without Grendel and his mum tagging along in the background.

  30. Surely the point about octaves is that if you double the frequency you get something that resonates with the fundamental. And if you double it again, the same occurs. So doubling has a real significance, both from the point of view of physics and from the point of view of the hearer. In fact, when you play a certain pitch on any instrument, you also excite a whole series of so-called "overtones" at the same time, which are frequency multiples of 2, 4, 8 etc above the fundamental. You also get a sort of resonance at the fifth of the scale. It sounds, well, harmonious. Whereas if you play

  32. It is not necessary to expect your planet / moon system to create this weather on its own. There could be a conjunction with other bodies in its solar system that shaded it or passed it through a dust cloud every 4 years, or near an eccentrically orbiting body or somesuch. Many succesful SF stories have been built on variations of this from The Dragons of Pern to the short stories of The Unorthodox Engineers.

  35. I’ve had a bunch of randos who’ve never even once posted here start “following” me in the last few weeks... I am notified when they begin following. My understanding is that the follow function is basically a subscription to get updates every time I post. My intuition is that it’s not being done for any positive purpose or because they wish to learn from me etc., and may in fact be a coordinated effort to learn more about me and plan for a social engineering attack of some sort. Maybe (hopefully) I’m wrong, but I’d simply rather not have followers. Can followers be blocked?

  36. 1) The current model of academic publishing is a #%&ing scam. Nowhere else would the creators of a product not only be expected to sign over their copy rights for free, but also perform the review and editing of others work for free, and have our institutions get financially reamed for access to the #$^ing work we created there in the first place. THEN, with the advent of open access publishing, they get to tack on fees to the tune of $USD 11,320 upfront to the %^(&ing authors. It's really no wonder that the profit margin in academic publishing is ~40%. 2) While the idea of open

  37. Perhaps joigus cannot dispute the correctness this statement, for he is a Physicist. But I can because it is just plain wrong. To the best of our knowledge Paleoclimatology tells us that the Earth has only had its present nitrogen/oxygen atmosphere for less than half its existence. And the oxygen was not a component of the original atmosphere. The oxygen was actually released as a waste product from lifeforms that existed before oxygen for example stromatolites. Naturally the climate was also different then. So if the climate changed again, so would 'biological life

  38. John, it's not my intention to prove you wrong, any more than it's very often my intention to prove myself wrong, for the sake of clarity and accuracy. Very often I take a back sit, click on the "follow" button, and try to learn from others, as you can easily check on the website's interface. There are many threads on which I'm just a follower. I strongly recommend you to carefully distinguish hostility towards you from rejection of your ideas, or even just honest intent to clarify your expression so that others can understand you.

  39. Absolutely. While one acknowledges that the ancestral wolf lies somewhere within any and all dogs, nurture far outranks nature in how that is expressed. This reminds me of another, perhaps less acknowledged truth: humans train dogs, but cats train humans. My current cat has trained me to rise at 3:00 am to give it its early morning feeding: resistance is futile. That said, I'm fundamentally a dog person. The sequence of several cats were all adoptions, supported by a wife who objects to dogs. I'm just suspicious about feline motivation: are they sitting next to me for warmth, or for comp

  40. The key to freezing certain things successfully is the speed with which that process is done. Slow freezing generates much larger ice crystals than fast freezing, causing greater expansion within the cells and rupturing them, hence the commercial use of pre-immersing in nitrogen. Clarence Birdseye is the guy that learned this from inuits in Labrador and came up with a way to replicate their method commercially.

And we can do much more than that - we can even probe the internal structure of the protons and neutrons themselves, and thus directly test the quark model. In particle physics we do not speak of “certainties”, but instead deal with a quantity called statistical significance. This essentially tells us the degree by which, given a sufficiently large statistical data set, an event is likely to be “real” (as opposed to being a statistical fluke of some kind). As
