How many atlases would fit into 20 terabytes? If an atlas has 200 A4 pages, each being 96,9375 square inches, fulfilled with maps at 600 dpi, 32 bits per dot, and one dot is 4 bytes; then one page is 140 megabytes, that multiplied with 200 equals 28 gigabytes. Then 20 terabytes equals to 20000/28 = 714 unique true-color atlases.
Uh, can't they already determine heights to high degree of accuracy with GPS or other radio wave methods? How would a picture be more accurate?
Yes, with accurate clocks, it is possible to determine the location of observer in the space, relative to satellites, quite accurately. However, for mapping this method is quite inpractical: To distinguish elevation of every 2.5 * 2.5 meter spot on earth, one would need to move the receiver unit through every spot of that size. The Earth's surface area is about 4 * pi * (6371 km)^2 = 5.101 * 10^14 m^2. The area of 2.5 * 2.5 m is 6.25 m^2. One would need to move GPS unit to 5.101 * 10^14 / 6,25 = 8.161^13 locations. Good exercise? On the other hand, something like radio echograph would need energy to get the signal through atmosphere, to ground, and back to the satellite, and therefore is quite impractical for heavy mapping sessions.
Coal is somewhere between one and thirteen parts per million Uranium.
Not to mention sulfur (that forms sulfur dioxide and causes acid rain), nitrogen, arsenic, mercury...
But really, I was under the impression that coal plants must filter out the heavy stuff, at least. How efficient we actually are at that? Anybody knows?
sure sounds to me like he did. maybe he meant playing it into the program w/a MIDI controller, but that was not inferred. in any case, if you just enter the sheet music, it's not going to sound EXACTLY how the composer intended.
He said "to enter the score", nothing about sheets! I interpreted it so that HE IS THE ORIGINAL COMPOSER, and therefore knows what he wants the music to sound like.
I don't think you understand what I'm trying to say- If a MIDI file is made from the sheet music, it may have the dynamics and tempo changes per the sheet music, and be "technically correct" in the sense that all the notes are being played as written, but it will not have the "feeling". Even attempts to humanize are not close to a human playing it.
I agree. But, in my opinion, nobody suggested making MIDI files from sheet music. There was only a poster who stated that that Midisoft's program plays the music exactly as he intends; he did not, however, claim that it will sound any particularly better than "unexactly played" music.
I was referring to the parent's post that software that could scan in the original sheet music would play it exactly as the composer intended, which simply isn't true.
The software scans the exact performance (to a certain precision), not the original "sheet". The original sheet is an inaccurate representation of the composers idea.
I was pointing out that the software probably wouldn't take into account things like accels/decels and other slight timing nuances (playing slightly before or after the beat, slight delays in pickup notes, etc)
MIDI takes those things into account
If you'll notice, anyone with any training in music will tell you that a perfectly timed note-perfect performance is stiff and robotic. It removes the exact things that differentiates a good performance from an amazing one.
You seem to be suggest that MIDI can only play back roughly quantized events, however, MIDI clock can be set to accurate as, say, microsecond (1/1,000,000 second). At such clocks, all variations and nuances will also be recorded.
a good pianist is one who reads the music and interprets it with the appropriate feeling, which often means playing notes behind/ahead of the beat, playing certain notes slightly louder or softer, or shorter/faster.
These are all saved in a MIDI file. MIDI does not give "general tempo", as you say, but exact timings of events.
ordinary computers can play a MIDI file that is technically correct, but sounds totally lame for lack of feeling. it's like Data's poetry.
If it lacks the feeling, then it is not "technically correct". If a perfect robot plays the same piano from a MIDI file, then the audio will be exactly same as original. (counting out hand claps, coughing, etc...)
Hi, first of all, I'm from Northen Europe, and will try to find some positive things about America. Others can continue the list...
For one thing, I think you americans are quite funny! I just watched The Incredibles DVD by Disney/Pixar, which was really well done. Also, looking at my room, I can only find processors made by american companies (Zilog, Intel, AMD,...). Putting so many transistors into so small space, I think you are very advanced.
That said, everybody is special, people are people, not nations!

ok, stupid fight :)
Read again: it does not, if he is a composer.

MIDI files contain time information for each event. Accelerandos and decelerandos will be recorded as they are played.

but i don't really see what he has lost
write your dreams down; let the world make them real for you
i think that down inside he feels better than, say, bill gates
