I learned something today... - Subaru Enthusiasts Car Club of the Sierras

Digital and analog audio for movies is commonly recorded on film via optical means. Pretty freaking clever... I'm actually a little amazed it works so well!

http://en.wikipedia.org/wiki/Sound-on-film

Quote:

Edge of a 35mm film print showing the soundtracks. The outermost strip (left of picture) contains the SDDS track as an image of a digital signal; the next contains the perforations used to drive the film through the projector, with the Dolby Digital track between them. The two tracks of the analog soundtrack on the next strip are variable-area (RCA Photophone), where amplitude is represented as a waveform. At present, these are generally encoded using Dolby SR matrixing to simulate four tracks. Finally, to the far right, the timecode used to synchronize with a DTS soundtrack CD is visible.

What did you learn today?

^ that. and some stuff about probability in my stats class.

My brain is full. Every time I learn something, I forget something else that was previously stored in my memory. Thanks to Scott's post above, I can no longer remember my mom's birthday...

that seems to be my case as well. Lately though I seem to have a lot of free space.

I learned that Adrian Brody is linked with the Predator remake. I don't know if he'll be playing the part made famous by Governor Arnold Schwarzenegger, Former Governor Jesse Ventura or Black Guy Carl Weathers.

But this is a good sign for his rising political career.

There's a Predator remake? Already? What's next, a remake of LOTR? I mean, it's been almost a decade since the 1st one came out.

Maybe movie producers should start filming movies in duplicate. It'll be so much cheaper if they film the remake while all the original sets, actors, cameras, etc are still around and set up.

It's important to have a role in life.

Then release the second one first and then you can release the prequel!

I learned that particle accelerators have been able to create minute quantities of antihydrogen, by blasting a beam of high-energy protons into a target using the accelerator, thereby creating a shower of subatomic debris. Powerful magnets separate out the antiprotons, which are slowed down to very low velocities and then are exposed to the antielectrons that are naturally emitted from sodium-22. When the antielectrons orbit around the antiprotons, they create antihydrogen, since hydrogen is made up of one proton and one electron. In a pure vacuum, these anti-atoms might live forever. But because of impurities and collisions with the wall, these anti-atoms eventually strike ordinary atoms and are annihilated, releasing energy.

I just learned that there's an asian Bill Maher.

MPREZIV · 2009-10-08, 11:13 AM

Except that Michio Kaku is much funnier than Bill Maher.

Indeed. But he's no Neal deGrasse Tyson.

Today I learned that Jaguar no longer produces parts for a 92 XJ220, and some guy at Sacramento Jaguar found out about the XJ220. I was bored.

Libila · 2009-10-30, 03:39 PM

I learned the answer to this question...

What is the relationship of the current to the voltage and resistance in a DC circuit according to Ohm's law?

is...

The current in amperes is equal to the emf in volts divided by resistance in ohms.

...but I don't understand it.

*Note- Studying answers isn't a good way of gaining knowledge.

V=RA
Very useful thing to know when trying to diagnose circuits and to blow fuses...

I would imagine so, but my job deals with water and fuel systems, so all of this sounds foreign to me

Dean · 2009-11-02, 08:02 AM

It is Ohm's law, and I forgot current is I not A, so V=IR or I=V/R.

In many ways fluid flow (water or fuel) are very similar to electricity if that helps. Check this page out... It has great examples.

That link is blocked by work filters but I'll check it out at a later date. Thanks for help though Dean!
