  1. Mpemba effect Great story about its origins on wiki. I think the moral of this story is that there are no stupid questions, just stupid answers. The effect is named after Tanzanian Erasto Mpemba. He described it in 1963 in Form 3 of Magamba Secondary School, Tanganyika, when freezing ice cream mix that was hot in cookery classes and noticing that it froze before the cold mix. He later became a student at Mkwawa Secondary (formerly High) School in Iringa. The headmaster invited Dr. Denis Osborne from the University College in Dar es Salaam to give a lecture on physics. After the lecture, Mpemba asked him the question, "If you take two similar containers with equal volumes of water, one at 35 °C (95 °F) and the other at 100 °C (212 °F), and put them into a freezer, the one that started at 100 °C (212 °F) freezes first. Why?", only to be ridiculed by his classmates and teacher. After initial consternation, Osborne experimented on the issue back at his workplace and confirmed Mpemba's finding. They published the results together in 1969, while Mpemba was studying at the College of African Wildlife Management.[9] Mpemba and Osborne describe placing 70 ml (2.5 imp fl oz; 2.4 US fl oz) samples of water in 100 ml (3.5 imp fl oz; 3.4 US fl oz) beakers in the ice box of a domestic refrigerator on a sheet of polystyrene foam. They showed the time for freezing to start was longest with an initial temperature of 25 °C (77 °F) and that it was much less at around 90 °C (194 °F). They ruled out loss of liquid volume by evaporation as a significant factor and the effect of dissolved air. In their setup most heat loss was found to be from the liquid surface.[9]
  2. Yes and no apparently. This isn't news or a question, I wasn't sure what to do with it so I stuck it here. Hot water freezing faster than cold water is a 'fact' I've heard several times now. Searched for an answer and found this. Found it an interesting read, Thought I'd post it. https://www.scientificamerican.com/article/is-it-true-that-hot-water/
  3. I have made no perverted argument about any of these things, just been accused. Just because I've heard it doesn't mean I support it. I made a comment in response to other comments, I've since been accused of being some kind of women hating incel who thinks they lie about rape. You're making outrageous assumptions about me, I find this deeply insulting. THIS IS NOT MY STANCE.
  4. I hope you're not referring to me. This is not my stance, nor have I said it is.
  5. You're accusing me of saying things again. I haven't said this. I've heard people talk about this and take this position. At no point have claimed this is my position. Not once.
  6. I'd prefer it if you'd stop lying about mine seeing as though I haven't made one.

  8. Utter bollocks I have heard this several times, were talking about rape. It can be a controversial subject so it tends to make the news, hence people talk about it. Why is it so hard to believe that there are people who believe in what the OP said, and these people have rang in to radio talk shows or been in the audience of a talk show and panel members have then discussed it. What's so unbelievably out there about this statement. You don't think going to prison for rape you didn't commit unfair. Okey dokey. Your still making out that I think most women are liars and that the stats prove it. I've said nothing of the sort. I've made no statements and taken no stance.
  9. What stance? What's being belittled? This is the problem, I've got no idea what stance you think I'm taking. I made a comment about having heard the same thing in the op, and now I'm being accused of all sorts of shit. I've taken no stance.
  10. Making what easy, what the fuck you going on about? What am I being accused of here? Once again you're making out like I'm accusing victims of being liars. You can f^^k off, you're pissing me off now. You're making all sorts of wild assumptions about me. 🖕🏻
  11. I'm not. The OP is about rape. there about the same anyway. 2-6% http://www.open.ac.uk/research/news/false-accusations-sexual-violence Between 2-6% of a million, what the experts say, what's the problem here? I've retreated from none of my posts. Why would I need to retreat. From what?
  12. Everyday feminism said it. Heres are better more reliable link which has about the same, 2-10% https://en.m.wikipedia.org/wiki/False_accusation_of_rape You're coming across like you think I believe the number is really high. I don't and haven't said I do. I just said that I've heard people discussing this in various forms and mentioned something about a football player. That's it.
  13. I believe what the experts say, about 2-7%. Maybe I'm wrong, but I get the impression you think my view is this, 'You can't assume the woman is automatically innocent because of how many of them are lying' It's not, the footballer story was just the same type of story that others had mentioned, so I mentioned one.
  14. Yeah that poll was pretty f**king grim. You're right, it's not a subject matter to be vague with. And I'll admit, the people I know with the view posted in the OP have mainly been educated by memes.
  15. To be fair, it says "some people" I think the problem is that the 'some people' are members of the general public or the extreme part of the me too movement. That's my experience. There probably having there views published to sell papers or make the debate more lively. In the U.K. The serious discussion is about removing jurors, and allowing the accuser to remain anonymous.
  16. Um, no. I've had conversations about and heard on radio about how rape victims are treated in court by over aggressive barristers. Part of the conversation on several occasions has discussed whether it would be better, for the women, to be presumed to be telling the truth instead of being a liar, which seems to be the current approach by the police. Theres always someone who rings in or posts an opinion favouring the extreme point of view. Nobody's saying this is an official line or something thats being discussed by politicians, it isn't, it's just a topic that rears it head now and again.
  17. Please explain how the f**k I'm supposed to get a citation from a discussion on talk radio, or a day time t.v. Show. What do you want me to do, secretly film my work colleagues talking about it, then post it here.
  18. "Believe such an outlandish assertion" I not gonna lie, that's really pissed me off. How do you know what we talk about over here? it's no assertion, it's a fact. And what do you mean believe, this isn't something I've been told. This is something I've come across in my day to day life. At work, at home, out with friends. I'm not sure why you think I'm a liar, I can assure you I'm not.
  19. Not from me you can't. These are things that I see discussed on daytime t.v., radio shows and the like. It was the story's of victims committing suicide that prompted it. There was one in particular that was on the news. These are the things they were discussing. It was the barristers behaviour that was the talking point rather than the victim/accused. It's one of those things that pops up in the news every now and again, presumably because they never actually do anything about it. There was a high profile one 5 minutes from where I live not long ago. Footballer Ched Evans was accused of rape, sentenced to prison. He spent 2+ years in prison before being found not guilty.
  20. I've heard this said several times now in the U.K. Over here though, there have been several cases of rape victims committing suicide after giving evidence in court. There was some questions about how aggressively barristers where questioning witnesses, calling them liars and blaming/shaming etc... I was under the impression the 'automatically believed' was more to do with protecting the victims from over aggressive barristers. The problem was what beecee and tim.tdj pointed out, the false accusations. If you're innocent then you should be able to defend yourself, having restraints on what your barrister can do puts you at a disadvantage.
  21. Wild ass guess, Some people like touching poop, and find 'disgusting stuff' interesting. So I think it's more learned behaviour than an actual thing in our brain. Going of the picture, that would suggest, to me anyway, the Sensory cortex, the Frontal lobe and the Temporal lobe is responsible. Complete guess of course.

  25. Great vid. Thanks for sharing. Best bit- 12 mins in, talking about using reactor grade uranium to get to Alpha Centauri in 120 years. We could explore the whole solar system with an engine like that. Imagine waking up on a spaceship orbiting Jupiter, or Saturn, breathtaking. 🖖🏻
