Reply to Agnis,
1. Sun
2. Superheated gas
3. no clue
4. very, very, very small - almost nothing
5. an object's relative movement state stays constant if not acted on by other forces
6. Coordinate system - a standardized system for describing the placement of points [& objects made of points] in some N-dimensional space.

1. The Sun, second closest is Proxima Centauri.
2. I would say, an ionized gas. However in medicine it is the liquid part of a blood.
3. Doughnut-shaped fusion reactor.
4. Zero, however the answer that they never rest is also true.
5. Newton's first law states that "An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force."
Inertia is an object’s resistance to the changes in its velocity.
6.
a) A way of describing the object’s position in the space.
b) The branch of physics dealing with the motion of objects without being concerned about what or how the source that started the movement is and/or was. (Sorry, iori_komei, I wouldn't have said it better)
c) I would say, a set of points with common geometric properties.

here i go again

1. A big ugly nasty black hole
2. A box with a cat and a poison gas capsule where the cat is neither alive nor dead until you look in the box.
3. Don't know. Maybe with big enough ones they tear the fabric of space, if not the natural tension of space may over long enough time flatten them back out.
4. Nova, Super Nova, Hyper Nova, and OMG NOVA . . . ! (4 was a joke)
5. A big ugly nasty black hole
6. Ohio, Florida, Pennsylvania, . . . . oops wrong states. Solid, liquid, gas, plasma

11. Just guessing i would say all of them
12. Marsium, Kizrium, Lekium?
13. A valence hint perhaps? Does it mean all the metals?

18. In any absolute form it is impossible
19. its directly below silicon on the chart.
20. Anti-matter - inverse form of matter, when it and regular matter touch they explode into pure energy.

1. What is the fastest way between two points?
Well The shortest distance is always going to be a straight line. On the surface of the Earth, the shortest distance is an arc with the center of the radius at the center of the Earth. This is called a "great Circle Route" because on a typical mat, it looks like a curve instead of a straight line. This is because a map is a two dimensional representation of a three dimensional surface.


2. What is the smallest theoretical thing in which everything is made of?


3. Name five sub-atomic particles?
Quarks, Gluons, Meons,

4. How many spatial and temporal dimensions do we exist in in?
nine
5. How many spatial dimensions do we percieve?
three
6. How many spatial dimensions are there?
six?
7. In theory how many temporal dimensions are there?
Uh, three?
8. Define the following:
Quantum physics.

a definition of physics based on probability functions
Temporal mechanics.
You got me.
Entanglement.
What I am into now


Not bad. I knew most of this stuff at one time.

How about another one?

What is the Dasien of the electron?

I've been wondering how much all the people pn ATS (atleast the ones that visit this section) know about science, so I came up with a semi-difficult test, Just put the number of the qeustion than the answer.

1. What is the fastest way between two points?
(HINT: There are two answers)

Well, based on our technology today, the fastest way between two points is a straight line where you blow all the red lights and do about 120. The other option is to simply close the space between the two points and make them the same, thereby making the movement instantanious. But we don't have the tech to do that yet.


2. What is the smallest theoretical thing in which everything is made of?

Ooo, good question! I was thinking maybe photon or quark, but figured I should check it out on the web, because I know there's smaller theoretical particles, just can't remember what they're called. Oh, I guess quarks are pretty much the smallest things beyond the string theory. Rock, rock on?


3. Name five sub-atomic particles?

lol this one's easy. We have our neutrons, protons, quarks, electrons and photons.


4. How many spatial and temporal dimensions do we exist in in?

4. lol good call on the number of the question! However, it's been theorized that the universe is actually 8 dimensions. It's the theory of octinions (sp). I don't have a website because I don't feel like looking something up I already know about, but look up octinions, let google correct your spelling, or rather mine.


5. How many spatial dimensions do we percieve?

Well, technically 4. However, we can manipulate only 3 of those and travel on a linear path through the fourth.


6. How many spatial dimensions are there?

It depends on your definition of space. Personally, I think of time as one of those, though general perception says there are only 3 spatial dimensions.


7. In theory how many temporal dimensions are there?

1. The fourth dimension is time. Temporal, by definition, is "of or relating to time as opposed to eternity". So there is one.


8. Define the following:
Quantum physics.

This is my favorite branch of physics. I actually convinced a friend of mine to change his major and major in quantum mechanics at Cal Tech. With, of course, a promise to share all his notes and everything to me so I could have a Cal Tech education without the piece of paper or cost. Anyway, quantum physics is the study of the smallest particles and how they interact with one another. Quantum computing is really interesting, since it moves away from the digital concept of on or off and moves to the statistical probibilty concept of, 70% of the time the particle will be spinning this way, 30% this way, and if you measure it, you change the results. My favorite joke of all time on a main stream television show was on Futurama. They're wathcing a horse race which ends in a "quantum finish." The professor lost, and exclaims, "No fair! You changed the result by measuring it!" I must have laughed for about 10 minutes after hearing that one...But I can't share it with most people where they appreciate it. Hopefully, this thread will appreaciate that joke
)


Temporal mechanics.

I'm actually not to well versed in this aspect of physics, but discecting in, I assume it's the study of time and it's mechinisms. How time behaves in different situations, though I could be very wrong.


Entanglement.

This relates back to string theory and previous experiments in teleportation. This theory states that particles feet, miles, or lightyears appart are directly connected, and if you influnce one particle, you inadvertantly effect the other particle. This also is in line with the butterfly effect, where a butterfly in Shanghi flaps it's wings and there's a huricane in Florida.



I'll post the answers to the qeustions on 1.20.05

Dang...Now I look like a poser. I hadn't gotten this far in reading before I got really exicted to answer. I guess it'll appear as though I read the post on the 20th and answered based on that. Oh well, it's all good, I had fun answering these questions and don't really care about outside perception, so it's all good


Great thread!

1. What is the fastest way between two points?

straight line, or, if you can bend the fabric of space/time, a wormhole.


(HINT: There are two answers)
2. What is the smallest theoretical thing in which everything is made of?

Yee...I should know this, but I'm drawing a blank. As a result, I'll answer not what it's made of but how it behaves: a wave.


3. Name five sub-atomic particles?

Good thing this isn't a grammer test, that's not a question
Neutron, proton, quark, photon, electron


4. How many spatial and temporal dimensions do we exist in in?

8? (See Scientific America, June 2004 for scientific backing to this figure. It's not proven, but has a very solid foundation)


5. How many spatial dimensions do we percieve?

We can manipulate 3, we percieve 4, though the fourth is a linear one way street. Blast, misread it, but I won't delete my first answer. Spatial dimensions, we live in 3.


6. How many spatial dimensions are there?

Again, 3, up, down, left, right, forward, backward.


7. In theory how many temporal dimensions are there?

1, Mr 4th, time.


8. Define the following:
Quantum physics.

My favorite branch, that which addresses sub atomic particles.


Temporal mechanics.

How matter behaves in time. Physical interactions as they relate to the fourth dimension.


Entanglement.

String theory, why one sub-atomic particle interacts with another no matter the distance between the two. Very rudimentary explanation, the reality is...just a little more in depth.


I'll post the answers to the qeustions on 1.20.05

Crap, it's well after that date, and here I am, posting after reading the subject of a thread posted at least 3 months ago. Ahh well, you posted the answers the day before my birthday. Neat!

1.) What is the equation of photosynthesis.
I have no frickin' clue. er... light + chemical reaction = energy?
2.) Name five components of an animal cell.
You're going all biology, and that's my weakest science avenue...But I'll try...don't laugh....too hard. Nucleus, mitocondrea(sp), cell membraine, cytoplasm, and...and...oy...uh...uh...lysosome?


3.) Name the planets within the solar system that do not have natural satelites.
Whew, less biology and more astrophysics/astronomy. Now I feel better. Mercury and Venus. At one point, Pluto was one, but "planet X' turned out to be a moon.


4.) A DNA molecule consists of two strands of ______, twisted together to form a double-helix.
RNA


5.) Name two types of proteins, (Based on size and shape).
...dang, can't.
6.) Name three parts of a plant, (i.e. stem). seed, leaf, root
7.) State the full biological classification of humans, (i.e. Kingdom, phylum, Class etc.). Can't do it without looking it up.
8.) Name, in order the biological classification series, (i.e. kingdom, phylum.).dang...again, see #7...


9.)What two languages are used in the scientific naming of species.
Latin and English Proper Noun


10.) Define the following:
-Phylogeny
Your what hurts?


-Taxonomy
stuffin' something. Oh, wait, that's taxidermy. Taxonomy is classification, isn't it?


-Isotope
...Aite, I just had some dental work done and am on Hydrocodine...I know this one, just can't think of it...Dang...Isn't an isotope some kind of modified something? Dang, talk about a brain fart...


-Sublimation
...Dang, two in a row. I know it, just can't get my synapses to fire in the right order to draw that out of my memory....
-Osmosis Diffusion with water. Ahh, now I don't feel completely stupid, maybe hitting a 40 or 42 on the IQ scale...




The end date to submit answers is March, 27the, 2005.
Anyone is free to answer.

Dang it, I missed this one, too...But I didn't see the answers after reading my last post on this thread.
