String Theory,..this is not detailed, but what do you think?

Here is a short video (not embeddable, sorry) on the Higgs-Boson and string theory by Dr. Michio Kaku.  Comments?

I don't like the chopping camera-angles, it makes no sense; someone thought it would make things look more interesting but it's just a distraction.
Nice talk, everything does come down to vibrations in the end.

Was that a fart joke?


Sorry, I couldn't resist.

No, where did you get a flatus-reference in there?

The last few words...

I guess I'm just a 38 year old who's still amused by immature things.

And I actually had this in mind when I thought of it.

Even I picked up on that one... ("vibrations in the end", for the record)

That was sarcasm :)

Though I understood some of it!

Don't worry...
Well, maybe if I was updated on the topic I would understand it, right now I'm completely into RC planes, not so much into science. But If I read up on it I would surely understand it.

WOW! You're awesome! That's some heavy reading! I could read up on physics, but I am dumb on electrochemical reactions!
Jan 28, 2012. 4:07 AMcolorex says:
Yeah, I know. I know that the acid in a battery produces an electrochemical reaction with the metallic plates, producing energy; but solar cells, I know just that they do work!
Jan 28, 2012. 2:25 PMcolorex says:
BTW Would you know how to make a smoke bomb? Non-toxic, easy and cheap? maybe also for a streamer on a plane?
Jan 28, 2012. 10:16 PMLithium Rain says:
Careful though - that's one ingredient short of gunpowder. :D (Also, on a pedantic note, it's not non-toxic - even ignoring the fairly standard "if you eat this or rub it on your skin it will be unpleasant" effects, it's a known producer of human carcinogens.)
Jan 28, 2012. 10:35 PMcolorex says:
Potassium nitrate is carcinogen?? The first gunpowder had 1 x coal powder, 1x sulphur, and 6x nitrates... Is this right?
Jan 29, 2012. 8:54 AMcolorex says:
Well, I'm careful by nature with chemical compounds. I plan on making smoke streamers for an RC airplane. I read on Wikipedia that potassium nitrate will melt with sugar at medium temperatures.

However, I need to know how to make sure that the mixture doesn't explode, but burns gradually. I know this has something to do with how it's packed into the tube that contains it. But I don't know for sure...
Jan 29, 2012. 12:31 PMcolorex says:
I need it to burn gradually into a tube, and make it last for a minute or so...
Jan 28, 2012. 11:03 PMLithium Rain says:
No, it isn't a carcinogen itself; under certain (fairly common) conditions it can produce them (nitrosamines, specifically). It's a somewhat pedantic point because AFAIK casual contact with limited amounts of potassium nitrate (as opposed to potassium nitrite, which is itself a carcinogen) isn't actually going to hurt anything. But, y'know, still technically makes stuff that gives you cancer. :P
 
I dunno - Google it. :P Point isn't that it will magically transform into gunpowder, but that with that combination you have a very strong oxidizer mixed with a fast-burning fuel, which you ought to be aware of before you start. :)
Jan 28, 2012. 11:10 PMLithium Rain says:
*Seems I remember that wrong - potassium nitrite isn't demonstrably itself a carcinogen, but is similar to nitrate in producing nitrosamines and having a _suspected_ rather than a confirmed link to cancer.
Jan 29, 2012. 1:33 AMlemonie says:
It's eating it with protein, like in bacon & other cured-meats, that produces these nitosamines.
Technically "bacon gives you cancer".

Jan 29, 2012. 12:19 PMLithium Rain says:
Well, or ingesting large dosages.
Jan 29, 2012. 7:08 AMSovereignty says:
I still remember what this topic started as, looking back....we should start heading back to physics starting with chaos.
Jan 28, 2012. 10:10 PMcolorex says:
Potassium nitrate... does that ignite with sulfuric acid?

And should it be powder sugar?
Jan 29, 2012. 12:34 PMcolorex says:
Oh, I remember now, school experiment: Sugar, potassium *chlorate* and sulphuric acid. Big fast flame, but not much smoke.
