    Vehicle brakes...

    Hi. If a vehicle centre of mass is below the blue line that joins shafts; applying brakes makes the rear axle heavier and increases rear tire friction with pavement resulting in shorter stopping distance. Is that right ?

    Chemicals in electronic cigarettes...

    Thanks.. Well, perhaps I should ask any member here that uses such devices to try with only water and no glycerin nor flavors nor nicotine before venturing buying one. Any takers ?.
  4. Hi. Been to several vendor stores asking for an electronic cigarette that uses/works with only water to make the steam and got the weird look. Does it fail to comply with the capitalism of profiting from flavor fluids which would be zero with only water or there is some reason the devices cannot make pure steam ? I was not looking for flavors nor nicotine which I have no crave for. Seems to me that flavorless steam nearly fulfills the habit of inhaling the 'heavy/denser air' sensation of smoking. Been a light cigarette user and never noticed any 'high' from tobacco. Just the habit. Gives me nothing.

    Beatles at Hollywood bowl...

    Thanks, String Junky. Youtube has ----> https://www.youtube.com/watch?v=FTUIP5eg5Xk with the worst audio the Beatles ever performed (from the noisy public) and reason they stopped touring as far as I know. A couple of vendors show DVDs but unknown if it is the same 'footage'

    Navy investigating UFOs

    On the 'tilted' background portions of video images; are those clouds, terrain, other ? Does the video correspond to radar imaging or visual images ? As appeared on television news ----> https://abcnews.go.com/GMA/News/video/pilots-report-encounters-high-flying-objects-63315985
  8. Hi. Seems like traffic lights could greatly benefit from artificial intelligence technology AI to save brutal amounts of fuel and time. What uncommon sensors would be needed for implementing such ?
  9. Another contraption accepting opinions: A submarine glider towing a boat. Linked by a hose doing the pull. Solar panel+battery on the boat compresses air. Flow of compressed air towards a bellows/bladder in submarine bow makes it buoyant with rising bow or sink with dipping bow when venting. Glider fins on submarine and cyclic compressing/venting should propel the contraption forward. Would the 'dorsal fin' or the 'tail fin' , or where be a better point to attach the hose for the glider to tow the boat ? This is a variation from an older thread ----> https://www.scienceforums.net/topic/72310-pour-your-brains-here-on-how-to-build-this-contraption/?page=2&tab=comments#comment-1102215

  12. Human imagination created gods. Gigazillion mankind-hours of praying have not produced any response from gods and will never happen, neither 'punishing ethical transgressions'. Surprising is that took an international research team in 'complexity science' to determine it.
  13. Big or small gods cannot give birth to complex societies. Gods do nothing; have never done a thing, never will.
