That's one of the most interesting new articles I've read lately,
besides the one in Cat Fancy about Cigarettes and Cats.

Sorry, I suddenly realized this is an ancient thread. But since you're here anyway, they thought they could make a perfect sphere in zero g, but found out that the high frequency radio waves they were using couldn't be absolutely controlled. The gist of it is the radiation frequency actually pushed the shpere into an oval. Another example of Newton's laws of action and reaction. I promise I'll never open another old thread. Pleeeeeeeze forgive me.

no, see that's cool.... you added relevant information that was worthy of re-visiting an old thread. I'm not entirely against revival of old threads.

What I am against is if you came across this thread and just said "oh, that's cool, I agree" ... it's considered bad form on the Internet is all.

Anyone who has actual information to add should be able to add it. If the threads were to auto-lock after say 500 days, then you can start a new thread and link to a locked one.

The real problem is people don't read dates, so if you bump up a thread that's 2 years old but has time sensitive information in it that can cause confusion, i.e. is someone went on to post about a class coming up, or a place you could go see these spheres - it would be way out dated, and would get peoples hopes up for no reason.

the other problem is drama - sometimes drama gets started on threads for no reason at all, and digging something up can re-ignite that drama...

I'm not saying _NEVER_ revive an old post, just have a reason for doing so.

Also, if you do a search, check the dates on posts you're reading to see if it's "dead" and if it is, you can start a new thread if the old one doesn't answer your question.

I ran across this very article about five years ago and as a result recruited Delbert Day to speak at the GAS conference in St. Louis in 2006. His talk was fascinating and the text is included in the journal from that year. His work with micro-spheres as a cancer drug delivery system is even more interesting. Amazing guy.

oops... just realized this is a very old thread. Sorry about that.

Konnichiwa Robin san, nice to see some of the old timers giving these kids what for. I too was fascinated by his cancer research--coolstuff indeed. Matane, Roger.
