  • to all the kids who go to bis and watched this video, i salute u!

    lol science homework =P

  • @Bryanclntn *facepalm* sigh... :P

  • Well I studied this doing Airline exams and must say this is a very well put together video.

    Well done.

  • Still did´t get it?

    There is a girl on the beach on a hot summer day and she is nude she wants to get her boobs tan. She is sitting in the sand so the sun burns hot on the boobs upsside the nipples, where its getting very hot so she got summer there and will get tan, downside the nipples is also abit sun but not much so she wont get much tan there cause there she got winter now. Shes laying on her back (changing Tilt of the boobs) Now downside the nipples its hot so she got summer&upside winter.

  • @ILoveDominikaDetko The nipples would stand for the equator which is the hottest place, I did forget to mention that in my "The best exsample mankind ever can get, about how the seasons work. " ! @mudokwon you are right and you forgot the expanding of the universe and the gravity by alot of other objects what does influence the suns path and speed in the universe , but from a lokal & relativ point of view in this exsample this doesn´t matter.

  • I LOVE LOVE LOVE HER VOICE!

  • 9:01 Santiago Bernabeau haha hala madrid XD

  • OH HAi

  • Thank you! :] I understand this so much more now, I'm definitely prepared for my test tomorrow, thanks!

  • @0xRedPandax0 bull zhit....

  • Is it just me or does this video make it sound like the northern hemisphere gets winter while the southern hemisphere gets summer all in the same day?

  • @yellowmusicfreak

    that's how it works

    

  • Still dont get it ; seems the tilt is always in the same place to me

  • @TheKenfig No the tilt does change the north point axis falls away from the sun sametime the south point to the sun and after that the north point falls(twists) to the sun and the south point away.The earth is like watching up in direction to the sun and looking down but not too extreme just a little.

  • I'm having trouble getting my head around the part starting around 4 minutes in. The tilt of the earth always points in the same direction relative to galaxy (give or take) but in the video the tilt straightens up to be perpendicular to the sun during the equinoxes. Can anyone explain this? I would have visualised that the sun is always at 90 degrees to the Ecliptical plane of the earth which is at an angle to the equator. Can't seem to put these two concepts together. Any help?

  • Thought about it more. So on the eqinoxes the axial tilt in the video doesn't straighten up so much as it gets viewed from front-on. So if the tropics of capricorn and cancer represent the limits north and south respectively for the overhead sun over a full orbit then the eliptical plane line resolves or connects through all points on the earth in between these extremities and indicates the overhead (90 degree) sun irrespective of season.

  • Comment removed

  • To say that the sun is not moving is completely wrong. The sun has a rotation and the sun is moving around the Milky Way.

  • you're taking the comment out of context...the subject is sun's path across the sky....in that context it is caused by Earth's rotation which is stated....the apparent path of the sun across the sky is neither caused by sun's rotation nor the Milky Way rotation. Of course the sun and galaxy rotate and therefore "move". Don't think of it in such absolute terms.

  • @Treetest63 is there a high res version of this video?

  • @Treetest63 Although the apparent move of the Sun through the sky is not related to the move across Milky Way, the sun moves that way anyway.

  • wow this is so helpful. Thanks!!

  • thanks... I've learned a lot from this video..

  • Nice.. I like what you've done with combining other videos in youtube..

  • gr8 video .... well done....

  • the viedo helped me a lot and i like it a lot

  • Great video. Thanks for uploading it :)

  • ok one question...how come there is an equinox ...i mean how can the two hemispheres receive the same amount of energy ..or to put it in another way how come the sun's rays make 90 degree with the equator when the earth is always rotating at an angle??

  • Think about it..... or watch the video???

  • @styleboy321 The tilt of the earth always points in the same direction, but as the earth orbits the sun, the orientation of the tilt relative to the position of the sun changes, pause at 9:20 and imagine the sunlight hitting the surface of the earth in the four different positions, you'll realize that in the autumn equinox, it doesn't really matter the Earth's tilt, both hemispheres receive the same amount of energy anyway, cause in that moment it's not tilted towards the sun. Hope this helps.

  • @styleboy321 think about it in a 3D perspective, if at one point, the 23.5degree tilt is away from the sun, its obvious that at one point (directly between those two points) the degree tilt is such that the equator is directly in line with the sun. or the sun appears to be highest in the sky (equinox)

  • thx man ...this ques was stuck in my head since last nite

  • this helped me SO MUCH! :D

  • tthanks for the vid. ! :) needed it for my science project...
