Reminder that CS is science

44 more posts in this thread. [Missing image file: ]
Computer Science is the science of computation; that much seems clear. Less clear is how to define science and computation in a useful and meaningful way. Generally, we might divide science according to two classifications: formal versus empirical, and pure versus applied. Whereas formal science (such as mathematics and much of computer science) relies on deductive reasoning from assumed truths, empirical scienc (such as physics and chemistry) relies on inductive reasoning from observed phenomena. Whereas the goal of pure science is to advance the state of scientific understanding, the goal of applied science is to use such understanding to harness the forces of Nature (in the broadest possible sense of the word) to achieve other goals. We might define computation as a transformation applied to a piece of information. In the broadest possible sense, computation is, then, any process which causes a change to occur in the universe. There is no need to provide any more detailed definition than this. Computer Science, then, consists of that part of the human endeavor which satisfies the following criteria: It is science, that is: It is either (1) formal or (2) empirical: 1. employs deductive reasoning from assumed truths 2. employs inductive reasoning from observed phenomena It is either (1) pure or (2) applied 1. seeks to advance the state of scientific understanding 2. seeks to apply scientific understanding to harness natural forces It studies computation, that is: It studies either (1) transformations or (2) information processes which map information from one form to another entities subject to transformations

If the two lightbulbs both have a voltage drop of 5v, when they are treated as one component, the single component has the same voltage drop right? or wrong?

Retard here. I'm writing a story and need some chemfag to explain some stuff about alkali metals reacting with water to me. So far, i've only found out lithium to generate the weakest explosion, and francium to be the strongest, yet francium being super dangerous i'm more interested in caesium. I wanna know what the intensity of said explosion depends on, apart from the element, IE, if water volume plays a role and how significant, or if submerging the thing would make it work differently. Also, I'm interested in how efficient this could be as a propellant, energy wise, if done inside a barrel, compared to say, black powder. Could it generate similar force using small samples of potassium/rubidium/caesium? Let me stress i know close to nothing about this and google hasn't been of much help. Thanks.

organic chemistry here how do i effectively study for this crap? my next exam covers alkynes, redox reactions, and conjugation/resonance/dienes my last exam covered alcohols/ethers/epoxides, alkynes, and NMR. for my last exam i memorized reaction mechanisms. and practiced NMR as much as i could. this didnt seem to work out as well as i would have liked. also i suck at doing NMR problems in less than 45 minutes. any advice?

Will chess be solved in the 21st century, /sci/? I think it will be solved before 2050, but wiki repeats a bold claim to the contrary. A "solved game" is a game where the eventual outcome is known, in the situation where both sides play perfectly. Examples of solved games include tic tac toe, connect four, and checkers. I think an 8x8 grid, half full of pieces, already quite tractable for play (by computers) against master humans, will be decided within 40 years, as computing keeps going. The research is just too far along for the researchers not to take things to their logical conclusion and "ruin" chess for good. :^) I haven't kept up with Go, however. Last I checked, they don't even have a decent algorithm to compete with a competent kid yet, let alone "solving" that bean-counter of a game.

Are the smartest people you know socially awkward or weird? All the exceptionally smart people I know were the Richard Feynman type, i.e. they had great social wit and you wouldn't know they were smart until you saw them rek a test. In my highschool, all the top 20 were jock WASP offspring. Granted the top 15 were just slightly above average with great work ethic, the top 5 were truly exceptional. All the gaming neckbeards, who stereotypes would dictate would be smart, were actually dumb as rocks.

Black holes

Lay mans view on science here Scientists don't know what lays beyond a black hole What is we took a bunch of entangled particles and sent half inside a black hole Would we be able to get any answers from the particles that remained on earth as to what actually happened the other particles sucked into the black hole?

Stupid questions thread.

Come one come ask your dumb questions that don't deserve their own thread. Please reframe from posting homework. We know you are only hurting yourself by doing that. My question is this. Is there some formula to be able to plug in numbers and it'll give you a decent estament of the number of marbles in a jar? I feel like there is some formula that involves the volume of the cylinder and the volume of the spheres that also takes into account "air gaps" for this but couldn't find it. I have to give a small lesson plan to some 8th graders about volumes so i though id be neat to show them that you can determine it for the most part by knowing the volume of a cylinder and the spheres.
