- Try clicking on the various channels to see videos posted to that channel - if you're into music you can click the Music channel to get more music sifts - go on and explore! Use the "hotness" when you have opened the channel link to get videos that have gotten a lot of votes, or use "newness" to have a look at the new sifts.
  When browsing sifts you like, have a look at the Related Posts list to see other related videos, click the tags under the video title to see more sifts tagged with the same tags or have a look at other sifts from the same user in the More Posts By list. If the sifted video is in a play list, have a look at the play list to see other interesting videos the Sift users have linked together.
  Enter the Sift Lounge to chat with online sifters about anything and everything, or read interesting posts in the Sift Talk forum.
  The Top New Videos list is always full of interesting, current videos. It is always recommended that you have a look through the Top New Videos, but also have a look at these:
  - Upcoming Unsifted Videos - active video submissions that neither are published to the front page nor archived to the submitter's personal queue
- Have you seen a really funny, surprising, scary, interesting, cute or in any other way extra good quality video?
  Post and share it here - VideoSift is the best video aggregator on the Web, where we share, discuss, promote, and interact with the best videos out there on the web. Post it here, and share it with the large community of video-interested users. And - you are guaranteed to find more very good videos here already!
  Mind you, we only share videos you discover that someone else has made; if you "self link," by posting a video you have made, have posted or have interests in, you risk the ban hammer - read the posting guidelines before posting. The sift is NOT for promoting your own videos - it is for sharing videos others have made.

Lagrange Points - Sixty Symbols

submitted by RFlagg

Professor Mike Merrifield explains Lagrange Points.

I think some of the L points are gravity "hills" instead of "wells", so they are unstable. The wells will trap things. If you put something into orbit around a gravity hill, they have to actually orbit around the hill.

In 2010, we discovered our first (and only) trojan asteroid for sun-earth at L4. I'm surprised the video didn't mention it.

I thought they covered 2010 TK7 and Cruithne (not a trojan but promoted as Earth's second moon for a while) before, at least in their Deep Sky video series, but I'm not seeing it... And not under tdarnell's videos either...

Meanwhile, I didn't think this would get in the top 15 let alone the top 5... I figured it would Sift though...
