  1. IMO- what is inside a house is a space. anything in that space is inside the house. Since the person in the box and also the box itself are in that space the person in the box must be inside the house. What is inside a Russian Doll? The next smallest doll or a set of dolls? Perhaps a version of Schrodinger's cat says we can't know until we have a look - lol.
  2. Yes - I had overlooked that.
  3. In the sense that any number system can be used for mathematical operations given suitable hardware and software, one answer is "nothing" (IMO). There can be a benefit in that it can be a help to a human wishing to convert the numbers in this system straight into decimal. And it is easy for a human to convert a decimal number into BCD. http://en.wikipedia.org/wiki/Binary-coded_decimal
  4. Perhaps hate is too strong a word, but certain official signs cause me to feel they don't really mean what they say. An example would be "Disabled Toilet". What is meant (and I do realise people understand) is that here is a fully enabled toilet suitable for disabled people.
  5. I once read a story about a fair maiden who kissed a frog who then changed into a handsome prince. So perhaps the tale of the donkey is not so far fetched!
  6. That reminds me - I haven't been banging on about Fermat's Last Theorem for some time!
  7. If the box is made of cardboard and it starts to rain then this might have an effect on your opinion.
  8. I think we should be tolerant of ideas we think of as "crackpot". I have been involved in Brainstorming in the past and it seems to me that a forum such as this could start with a "crackpot idea" which ,as the thread develops, gradually turns into a sensible argument or solution to a problem. http://en.wikipedia.org/wiki/Brainstorming
  9. I have heard it suggested that the value of grandparents as back-up for parents in the event of the early death of a parent may have been, in historical times, a valuable factor in the survival of infants. I have also read that this might have been a factor in the evolution of a life form that commonly lives well beyond what is necessary for the safe maturing of offspring. These days it seems to be that "The Bank of Granny and Granddad" is a useful backup for "The bank of Mum and Dad" which seems to be essential for the development of the grandchildren - (rueful lol).
  10. IMO the only kind of dog that has been in any sense bred for a companionable relationship with human beings is the humble mongrel. My family has had a few much loved examples over the years. Nobody worries much about what they look like and they aren't worth a lot, so if they turn out vicious and bad tempered they are likely to be taken on a one way trip to the vet before they have a chance to reproduce.
  11. See if this helps:- Imagine a solid wall that is free to move along the ground. Perhaps in the form of a vertical thick steel plate on casters. Imagine the two cars coming together one on each side of the wall. The wall would not move and both cars will suffer the same amount of damage as if they had hit a solid immovable wall.
  12. If you want to read a lighter, more detailed, explanation which agrees with Phi's comment then follow this link:- http://ca.autoblog.com/2010/11/21/road-myths-physics-of-a-head-on-collision/
  13. I would like to see photographs showing this. Also I Presume that you have evidence to show the mixture of materials in each pebble. These are tests that I would think easy to do.
  14. If what you say is true then cutting through a pebble should should show evidence in the form of rings as the material accumulated. Does this happen?
  15. Consensus is a weaker thing than unanimity as some of the group will accept the decision of the majority without,themselves, being really convinced. However,I think that a lone voice in the wilderness is more likely to be wrong than a decision brought about by consensus within a group. By the way as far as I am aware The Big Bang is still only a theory.
  16. You say you can feel vibration in your chest. IMO this is unlikely to be your chest responding to EM waves of 50 or 60 Hz. I wonder if the room you get this sensation in is subject to a low level of mechanical vibration which is causing resonance within the room. If the room is at resonance you would find a place or places where the effect is amplified. This could be set up by something like a compressor running, or even by traffic running on a nearby road. It would be somewhat like the way your chest can respond to low notes played on a church organ. This is just a thought.
  17. Your worry is justified. I think you have seen for yourself that the generator will not produce enough power to drive the fan.

    Optics

    Sorry if no help. Not my field, but since nobody else was contributing I thought this video would perhaps put you on the right track. The video explains lateral inversion, but perhaps doesn't explain lack of vertical inversion. My apologies. Apparently what you have asked is a surprisingly difficult problem (of which you might be well aware). You might like to read this link:- http://www.answers.com/topic/mirror-reversal
  19. I have wondered whether the victims of a guillotine have a second or two of consciousness before blood loss brings oblivion. If they do then I think the basket should be lined with soft padding. It seems a shame if your last experience on this earth is a hard bash on the nose, especially if you can see it coming!

    I haven't done light ray diagrams since I was at school, but this link has a video that might provide the information you seek.
  21. Sea water is at its most dense at about 4 degrees celsius, which is pretty cold.
  22. In the 1960's I worked with Bloodhound Guided Missiles. These used two ramjet engines for most of their flight, but needed four rocket motors to get them around mach 1 before the ramjets became useful. If you want to see one in action follow the link. http://www.britishpathe.com/record.php?id=67192
  23. This is a dream that many people have had over many years. However, it is firmly believed to be impossible.
  24. I don't think anyone actually thought it was feasible. Just people having fun bouncing ideas around (IMO)
  25. The turbine may be weightless in space, but its mass is still there. If two surfaces come into contact with each other (say the shaft and the bearing shell) then the contact between them would be quite hard and for the time of the contact there would be friction. Another effect of mass could be imagined - If two large spaceships came together and you got in the way you would be squashed.
