1. ## Hiatus

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

38. ## What If the Earth needed Global Warming in its Atmosphere.

Having re-read the posts in this thread my personal summary is, I need the Earth, sadly the Earth does not need me.

39. ## What If the Earth needed Global Warming in its Atmosphere.

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

40. ## Questions on Thermodynamic Free Energy.

John, Just how easy do you think it is to realise that ambition? The heart of your OP, the nature of far-from-equilibrium thermodynamics, wasn't even a recognised field of study until the the work of the Russian chemical engineer Ilya Prigogine was brought to general attention with his award of the Nobel prize in chemistry in 1977 - that's half a century after the first firm principles of quantum mechanics and general relativity were established! It isn't an easy subject. Do you really expect to become fully conversant with it with a few brief exchanges on a general science

41. ## Dogs and/or Cats

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

42. ## Carrots in the Freezer

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.

43. ## Does the expansion of space mean anything for the movement of matter in space?

It's a mystery how you reach this conclusion from such a straightforward statement P RS: X J: I agree P RS: You think X is not true?

44. ## Does the expansion of space mean anything for the movement of matter in space?

Quote from jcMcSwell : " Dark energy is probably the only actual force (that is not expansion itself) that will push the two objects apart over time ". Excuse me , dark energy is not an ACTUAL force .

Received my first Moderna vaccination tonight. The pharmacy had a handful leftover they needed to stick in someone by the end of the night. 😁

47. ## Einstein's Simplicity

Yes, and we moved forward from there. We know a lot more now than we used to, so we won’t be going back to 1963. Yes. 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

48. ## Why are professors such assholes?

So... the guy who thinks profs are arses is not treated with respect by profs. The other people are treated with respect. I wonder if those observations are related.

49. ## Why are professors such assholes?

I'm a tenure track professor. I usually get somewhere between 50 and 100 emails a day. I allocate about 45 mins twice a day to responding to them. I sort them by importance, then I answer in order until the time is up. Then I delete the rest. Emails go unanswered every day because I could literally spend the entirety of every single day responding to them, and I have teaching, research and administration to do. I tell my students that if it's important, send it again and tag it as important, or if it's important AND urgent, bang on my office door or call my phone.

50. ## Is Suicide right or wrong?

At my current age of 76 years, I'm still enjoying life and have no real health problems. In actual fact I plan on living forever: So far, I'm doing OK. 😉
