  1. What a dumb explanation.... If observer is facing south, at 6am sun will be at his left, noon straight in front, 6pm to his right, midnight, behind him, as shown in that stupid animation.... if the guy is facing south at all times, at midnight, the NORTH pole is BEHIND him(because, you know, he's facing SOUTH), just like they show the sun in that animation...the north pole is between him and the sun........ whats so hard to grasp? zig zag.... SMH Now... I DID see a video of someone asking folks on the street how many sides a triangle has, and they got it wrong, so.... I guess anything is possible.
  2. I showed you evidence... through ballistics ie Coriolis effect... proves we're on a sphere that rotates... you can even go buy a gun and conduct your own experiments.
  3. wow, I bothered to watch those videos.... that guy jumps around with his arguments... adding in crap filler that doesn't add to his point at all... HOLY CRAP! When you stand at the pole, just moving a few feet to the left or the right covers the longitudes from the east to west coast of the USA!!!! WOOOOOOW!!! Who knew? Next he'll be amazed at how he could stand 3 ft from the north pole, walk in a 10 ft circle , and profess he's just circumnavigated the globe in 31.4 ft What a load Not a single experiment done to disprove a globe earth.... well done
  4. What you're saying is true... the sky is completely different in the summer vs winter for someone at the equator.... Someone at the north pole never sees the southern constellations, someone at your missing south pole never sees the northern constellations... Answer It depends on where you live, specifically your latitude, on the Earth. At the North Pole (90 deg latitude), for example, the North Star is directly overhead and any stars within 90 degrees of it are visible year around. At the Equator (0 deg latitude), however, the North Star is on the horizon and only stars withing 0 degrees of it (ie. no stars) are visible year around. In the more likely situation that you live around 45 degrees latitude, the North Star would appear 45 degrees above the horizon and only stars within 45 degrees of it are visible throughout the year. This would include constellations like Ursa Major (the Big Dipper), Ursa Minor (the Little Dipper), Cassiopeia, Draco, and other so-called "circumpolar" constellations. Answered by: Paul Walorski, B.A., Part-time Physics Instructor Answer It depends completely on where you live. EXPLANATION: To understand the answer to this question, you have to understand how Earth is situated in space. Earth's axis is tilted, but it always points the same direction. That direction happens to be straight at a bright star named Polaris, which is commonly called the North Star. Earth revolves once a day, and where it is in that revolution when the sun sets changes throughout the year. That is why the constellations you see at night change. If you lived at the North Pole, the North Star would be directly overhead, and the constellations would wheel around you like the horses in a giant carousel would if you stood in the middle. You would only see half of the constellations, but the same ones would be in the sky all the time; none of them would ever set. However, for some parts of the year the sun never sets either! And that's no good for seeing constellations. If you lived on the equator, it would be completely different. The giant carousel would be on its side. The North Star would sit right on the northern horizon. Each constellation would spend half of its time in the sky. Each one would come up in the east and set in the west 12 hours later. However, ,each day, the sun would blot out half of them and the ones it blotted out would change throughout the year. Once again, you couldn't see any of them all the time. Most people live in between those two extremes. Halfway between the equator and the North Pole, half of the sky acts like it does from the equator, and half of it looks like it does from the pole. The giant carousel is tilted halfway up, and the North Star is halfway up the sky. The stars opposite the pole rise and set each day, but the stars near the pole (and the North Star) go in circles. If one goes in a small enough circle, it will be up all night long, every night. (We would call that star "circumpolar".) If the circle gets too big, the star will be cut off by the horizon some of the time.
  5. http://www.physlink.com/education/askexperts/ae706.cfm Who told you you can see all the stars? We orbit the sun, it blocks different stars at different times of the year... duh
  6. funny that those star trails match in arc to the time passed..... every degree of arc is 1/360 x 24h long.... so you're saying the universe spins around the north star every 24h?
  7. Coriolis ... ballistics.... 100% proof we're on a sphere, and its rotating. I see you completely ignored that proof. Sweet God almighty fuck with the airplane example... hat off hanging head shake/ facepalm.com ....
  8. The 200 proof video... a good chuckle. "hot air balloons and helicopters should just have to hover to end up somewhere else".... thank god seatbelts were invented, as when i was a kid, and jumped off the seat of the car going down the highway, i would slam into the back window, as the car was doing 60mph. This guy never heard of Newtons laws of motion.... Another one... "cannon balls should land differently depending on direction of fire... but they don't...".... well, they do... its called the Coriolis effect. Explain the proven results of a spinning round Earth that affects ballistics.... Explained nicely here:
  9. Laying down and not reporting the bad ones is worse. Dave would turn a blind eye till it becomes the norm. "let me see your papers sir"
  10. I had to turn the sound off, then just suffered through the convulsions to see wtf you were on about... She's hot, but if that was the only video ive ever seen of her, I'd think she was doing a spoof.
  11. took a bit of time, but it can be solved. I had to use pencil and paper.
  12. normally they put two 'of ' together , or the the... which you skip over
  13. What a beauty... had to check the garage to see if mine was missing.... 500 miles and all
  14. You need to be riding (catwalking) on the rear idlers for lug height or belt thickness to matter.... Nobody would gear for catwalking, so lugheight does not affect drive ratio.
  15. 95 years.... Universe 14 billion. Earth 4.5 billion.
  16. Thank God it wasn't the guitarist John McLaughlin.... that would be a sad day.... 74 and still kickin.
  17. I don't think it resembles a clock radio either, so......
  18. clock radios use the power cord as an antenna... ipods etc use the headphone cord..... derp.
  19. Can you switch to mono FM? The signal will be cleaner, but you'll lose separation... better than nothing at all....
