How do you play music in a Visual Basic 4.0 Program
blike replied to apollo2011's topic in Computer Science
"Dim sFlags As Long sFlags = SND_ASYNC Or SND_NODEFAULT sndPlaySound "FileName.Wav", sFlags" Where did you put that part? It shouldn't be in the declarations part of a module, it should be where you want the action performed.. -
I'd like to discuss this further. What, to you (anyone), would indicate a biological system being designed?

Haha, I'm sure you've done the rope thing. Like cracking a whip except with a long piece of rope. I don't know too much about the physical processes of electricity, but I'll take a stab at the general principle behind it. There aren't really "carrier particles". Its the EM field between the electrons. Imagine all the atoms in a copper wire lined up. The electrons around the atoms would be like the tennis balls in your thought experiment. While the FLOW of electrons from one atom to the next is rather slow, when one of them changes position, it effects electrons all the way down the wire at near the speed of light, because of the electromagnetic fields between them interact with each other at the speed of light.

But what if we stretched a fundamental particle out and did it hehe

MrL's talking about EM-repulsion on the atomic level. In other words the only way one atom of an object knows what the atom's around it are doing is through their electromagnetic field. Electromagnetic fields travel at the speed of light. When you move shake the stick (or spin the wheel), the reason the atoms at the other end of the stick move is because of the changing electromagnetic fields from one atom to the next. Its a chain reaction moving down the stick. EM-fields interact at speeds of C. So essentially you have a speed limit on how fast the wave of motion can travel down the stick. This motion seems like it would be instantaneous because of the short distances with which we usually interact. But if we were to measure very precisely even the shaking of a stick or spining of our car tires, it wouldn't be quite instantaneous. Have you ever held one end of a rope up in the air, then suddenly pulled it down and watched the subsequent wave of motion? Thats what it would look like on a large scale.

I posted a similar question once which involved a long stick that would take light a few seconds to transverse. If we shook the stick at one end, wouldn't the other end move instantaneously? I would assume that the speed at which the energy travels through the balls has a limit at C, and hence the last ball would never fall out before the light reached you. It might seem wierd to think of it like that, because the motion seems instantaneous in our minds. I'm sure someone can explain better than me, but thats the basic gist of it.

You're welcome to argue, just be nice! No personal attacks.

OH MY GOODNESS. I CANT BELIEVE IT Haha, this forum is actually good for something.... I can't believe you knew what I was talking about.

Anyone know that classic rock song that starts out with a guitar that sounds like a motorcycle accelerating and shifting through gears? I know the line "we still kick ass" is in there somewhere too. ::looking for needle in a haystack::

I like VB, but sometimes its hideously slow compared to C / C++. Especially in my pi calculator. The application in C calculates about twice to three times as fast as my visual basic application. Of course, BASIC being the only language I know well, I must say its my favorite language

Was this an AP exam?

I've always wondered why the other cowboy insists on hiding the fact that he's online. = sees all.

Hey, I'm the cowboy here.

The true scope of Natural Selection
blike replied to Zeo's topic in Evolution, Morphology and Exobiology
Right, I was referring to the all encompassing theory that accounts for our existence; including the process of evolution by natural selection, but not exclusively. -
The true scope of Natural Selection
blike replied to Zeo's topic in Evolution, Morphology and Exobiology
Don't confuse theory with hypothesis. The former is well supported, the latter is a guess. I think most (credible) scientists would agree that evolution is still a theory. -
Whoah, chill. You're misinterpreting what I said. Re-read what I said. "This line is a thin line to walk however, because those that tip-toe it are close to trampling all the science thats been laid down rather painstakingly behind evolution." Did anyone else misunderstand? By trampling I didn't mean "disproving", I meant disregarding what many scientists have dedicated their lives to uncovering.

I can't remember my reasoning behind that.

Mars: Life or no Life. That is the question
blike replied to apollo2011's topic in Astronomy and Cosmology
Maybe some ancient frozen bacteria, at best. -
I hate sorcerynet. Anyone have any suggestions on good (reliable) networks? I was thinking about EFNet, but that requires an eggdrop, which my host will not host. DALnet is pretty good, but not as reliable recently. Any suggestions?

are you EVER home? it always says missed me

BTW I picked up this book a few days ago. I'll let you know how it is

WASHINGTON (Reuters) -- A cold virus genetically engineered to help it sneak into cancer cells can kill inoperable brain tumors in mice, U.S. scientists reported on Tuesday. The effects were so stunning that the National Cancer Institute and the U.S. Food and Drug Administration are rushing to test the approach in people with brain tumors. If it works, it will be the first treatment for malignant glioma, the deadliest form of brain cancer. Lang and colleagues used a genetically engineered form of a common cold virus known as an adenovirus. They weakened it so it could not affect healthy cells, then gave it an added genetic "key" to open the door into cancer cells. When they tested it in mice injected with human brain tumor cells of a particularly nasty nature, called glioblastoma multiforme, it apparently cured 60 percent of them. "The animals lived 140 days -- we took the brains out at that point and found no tumors there," Lang said in a telephone interview. Normally, mice injected with human brain tumor cells die within 20 days. Full article here
