Ok... you're falling down the hole. A few assumptions to make things simple: a) no air. Lets pretend its a vacuum b) intense heat etc. doesnt kill you near the center c) the earths mass around the hole is perfectly distrubuted as a sphere The force of earths mass pulling you to the center becomes less and less the closer to the center you get. If you also pretend that you are a perfect sphere your self (or at least perfectly symetrical) then what will happen is when you pass directly at the center of earth your change in velocity will be 0, but your actual velocity will be some arbitary (and probably very high) number. From the center on the earth is pulling you back towards the center and the farther from the center you get, the more earth there is pulling you down. so G (being force of gravity) is increasing. As your velocity slows down more and more it will reach 0 RIGHT when you reach the surface on the otherside, and then you yo-yo all the way back down. Eventually you'll end up colliding with a side though, since the rest of the mass in the universe is effecting you lol. Now, you can add all the assumptions back if you like. If you add air resistance, the air resistance will become greater and greater the closer to the center you get, hence your terminal velocity will increase. Your terminal velocity will NOT hit 0 however. The only time terminal velocity goes to 0 is when you hit a brick wall haha A few people dont seem to understand what terminal velocity is... Its when Force of friction and the Force of Gravity equalize and cancel each other out (exactly why you stay at the same velocity, no acceleration is happening). Because Ff is increasing and Fg is decreasing the point they equalizing gets smaller real fast. Thats pretty much my 2 cents in the matter. Just a question, I forget how to use the fancy equation text, what are the tags for it again? lol

I like the way they did time travel in back to the future... There wasn't any paradoxes (or less of them lol) because when they went back in time they created a parallel timeline to their own... so by changing things in this new timeline it doesnt effect the fact that they traveled back in time from their own unaffected timeline. Confusing... the crazy scientist guy made a good diagram of it in the movie lol Back To The Future rocked though

no apparently I had it wrong lol. 860MHz was my processor speed not RAM speed. I'm on the better one right now though 1.8 GHz Probably nothing to some people... a friend of mine was going to buy from alienware, he could get a PC several times better then the same price of a Dell Anyways, can someone explain to me how you find out RAM speed anyway?

oh pffft. what is ram speed measured in? hz?

With enough scientific funding in the area, we could probably have people on mars permanetly right now if the need was great enough...

533 is pretty slow... I'm on the really cruddy comp here and mine has 860MHz lol

Its good that this was refreshed. The IRC has moved to: blackcobalt.no-ip.org Port 6667 Channel #SFN

I noticed a pattern when you would square a number and add the digits together... ex. 15*15 = 225 2 + 2 + 5 = 9 1 - 1 2 - 4 3 - 9 4 - 7 5 - 7 6 - 9 7 - 4 8 - 1 9 - 9 10 - 1 11 - 4 12 - 9 13 - 7 14 - 7 15 - 9 16 - 4 17 - 1 18 - 9 19 - 1 20 - 4 I won't go any farther, and just assume that it keeps going. Does anyone know why though? as in a proof as to why?

In just FIVE minutes you should learn to quickly multiply up to 20x20 in your head. With this trick, you will be able to multiply any two numbers from 11 to 19 in your head quickly, without the use of a calculator. I will assume that you know your multiplication table reasonably well up to 10x10. Try this: Take 15 x 13 for an example. Always place the larger number of the two on top in your mind. Then draw the shape of Africa mentally so it covers the 15 and the 3 from the 13 below. Those covered numbers are all you need. First add 15 + 3 = 18 Add a zero behind it (multiply by 10) to get 180. Multiply the covered lower 3 x the single digit above it the "5" (3x5= 15) Add 180 + 15 = 195. This is interesting actually... Following the instructions: 10+x*10+y 10+x+y 100+10x+10y 100+10x+10y+xy Using FOIL: 100+10x+10y+xy This thread is for math tricks in general... If anyone has a math trick thats stumping them just post it here

Think of a secret number. x Add 5. x+5 Multiply by 2. 2x+10 Subtract 4. 2x+6 Divide by 2. x+3 Subtract your secret number. 3 Now you have 3! Yes I do Think of another secret number. x Double it. 2x Add 6. 2x+6 Add your original number. 3x+6 Divide by 3. x+2 Add 5. x+7 Subtract your original number. 7 Now you have 7! Yup

YAH! I say Mc, you say A I say Dairy, you say B I say Taco, you say C I say Coca, you say X I say Burger you say Y? I say Sub you say Z er... still dont get it lol

Yes, mathematics at last! Do you know what the ionization energy of iron is? we could figure out how energetic a photon would need to be... Found it here I dont know how to do the calculations though lol. but its 762.5 kJ/mol Where'd you get /6.022*10^23?

Yah, the space shuttle is old... they need to just rebuild from scratch with todays technologies.

Yay! you used quote tags

Ice A Mc Use A A Ice A Dairy Use A B! Ice A Taco Use A C Ice A Coca Use A X Ice A Burger Use A Y? Ice A Sub Use A Z ? lol I dont know, grasping at straws probably

Also, Aye, Bee, Sea, Ex, Why, Zee all sounds like A, B, C, X, Y, Z

Give up double big macs for the rainforests...? *leaves to ponder which he likes better* lol The way I see it, the destruction of earths enviroment will probably propel exploration of other planets, and the probably colonization of them. Sort of like, ok we screwed up the last planet, lets try this again... lol

Alpha-137: First of all, just cuz its really annoying me (lol) use the quote tags! as in QUOTE="there name here" in [ ] brackets, then whatever they said, then /QUOTE in [ ] brackets. Like this: that was obviously a joke hehe but you get what I'm saying by using quote tags. That out of the way, you need to make an experiment thats VACUUM PROOFED. this is big, because of the heat / cold you are using you are creating air currents which could very easily effect your experiment. Pretty much, do the entire thing over in a vacuum chamber and get some hard data on it. Do that, report back, and we'll see what you have

amosquitoes: a) no zeros on the top row (no 2 digit number can start with zero as in, 02 at the end). b) 14 isnt prime, 98 isnt prime, 35 isnt prime and 2 is the only prime you put down. ALL BUT 1 are prime.

And if thats really you mustang292 then you must be Jim Carrey!!! *snickers*

Apparently, iron was just his main example. Why he put so much empasis (even naming his theory "Iron rules the universe") I don't know... It's because of magnetism... and irons magnetic. That may be why he goes on about iron.

And thats your problem right there... thats a good portion of the time where "crack-pottism" springs from, and why crack pots defend there theories so vehemetly...

yah... I've never seen my cat cough up a furball, or have found any evidence that she has been coughing up furballs... but shes never let outside, so she doesnt eat grass

I always thought that dogs were omnivores till someone told me that they are only supposed to eat meat

I think they took the part about the large top canopy trees dieing off and threw away the rest... selective reading
