1. ## Intelligen Design vs Evolution

some news http://www.newscientist.com/article.ns?id=dn8061 http://www.newscientist.com/channel/being-human/mg18825201.200
2. ## Calculate the amount of information?

found some info here http://www.metanexus.net/ultimate_reality/zeilinger.pdf and this one http://www.space.com/searchforlife/quantum_astronomy_041216.html it's more like psychology than physics.
3. ## Calculate the amount of information?

I see no reason to catalog it as 'not there' because we can't retreive it now.If we can't detect any black matter then it isn't there. You must realize that this is calling it different based on what you don't know yet. Besides I don't think that the heisenberg uncertainty principle wil survive the next 50 years.
4. ## Calculate the amount of information?

So what are you trying to say that it isn't infinite because of planck etc...? I already assumed that.
5. ## Calculate the amount of information?

My definition of information in my question: everything you need to define it exactely at a certain time. I don't think the heisenberg uncertainty principle has anything to do with it. It's not because we can't retreive the information that it isn't there.
6. ## Calculate the amount of information?

So you say that an neutrino contains an infinite amount of information?? I don't want to store it I only want to know how much there is. "even with winrar" that was funny Doesn't the amount of information stay the same even if you compress it. edit: Found this article that gives some idea's http://www.cise.ufl.edu/~mpf/lec3.html and this one: http://www.math.uwaterloo.ca/~akempf/summary.shtml
7. ## Calculate the amount of information?

Hi, Does someone know if there is a way to calculate the amount of information of something (object, area, atom)? Would it have a unit?
8. ## Intelligen Design vs Evolution

I just want to add the reason why it's called 'Intelligent design' and not 'The creation of God' or something like that. They would have trouble with the First Amendment "Two clauses in the First Amendment guarantee freedom of religion." So the name ID is just a new package of the same thing to avoid conflict with the First Amendment.
9. ## Wild gorillas seen to use tools

older news: http://msnbc.msn.com/id/6689205/ Maybe they start using tools now because they didn't need them before. The same is true for humans according to history many more inventions are made during a war/crisis. Do you think we would know how to make an atom-bom if there weren't some big wars in our past?
10. ## Heat Concept

http://www.math.montana.edu/frankw/ccp/calculus/des/intro/cooling.htm here you have a complete worked out example: http://v5o5jotqkgfu3btr91t7w5fhzedjaoaz8igl.unbsj.ca/~talderso/UWOnotes/UNIT10.pdf
11. ## Heat Concept

Can you measure the temperature of the sphere? What you can do is making it half theoretical half imperial. Put the sphere in the freezer (no liquid nitrogen required) after a while measure the temp take it out wait 10minutes and measure the temp again. The time and temp change will give you a constant that you need in the formula to calculate any temp change for any time.
12. ## Heat Concept

You assume that their heat transfer is the same at temperature T for both. If one has twice the surface in contact with the cooler body it will cool faster. (with the same heat capacity)

15. ## Specific heat capacity question....

Just write down the equation with at the left side the total sum of energy before the mix and at the right side total after the mix. Then you will also notice that it's independant of the heat capacity since they are the same for both.
16. ## Help for direct current circuit

Yes, a big problem will arise be very careful when making that circuit particles will collide and a nuclear explosion can occur. (see my previous post) If you want to do the left side first and then the right side then you can make a Thevenin equivalent circuit of the left part and also the right part and then connect them and calculate that current (this is your A-meter current). http://hyperphysics.phy-astr.gsu.edu/hbase/electric/thevenin.html you can find all basic info here: http://hyperphysics.phy-astr.gsu.edu/hbase/electric/dccircon.html#c1
17. ## Help for direct current circuit

Just apply Kirchhoff's law's or if you don't know that assuming that the resistance of the A-meter is zero you can just connect the two then AE and BE have the same voltage same for the other side so you can calculate the current of all resistors and the one that goes through the A-meter is the one that makes the total current in point (A or B) equal to 0. Currents can't flow in the two direction at the same time but when you applying Kirchhoff's you don't need to know the right direction just guess one if it's the wrong direction then the calculated current wil just be negative (meaning not flowing in the direction of the arrow)
18. ## So were did we NOT find organic molecules?

Saturn's Moon Titan is next http://www.space.com/scienceastronomy/050917_titan_shore.html
19. ## Hall Effect held Capacitor?

You have to be more clear what you are trying because from what I see you don't really understand the meaning of a capacitor and capacity of a capacitor
20. ## Nubbie math problem help

22. ## forseeing the future or Psychological creation

Well predicting the future and act on it is the main task of science and your brain Some are just better than other and statisticaly an accurate hit will happen ones in a while. Just my thoughts on it (although I know I'm right )
23. ## equation

Give me the positions of two more points of your parabole and we can give you a and b if you understand what is show here you will know: http://www.glenbrook.k12.il.us/gbssci/phys/chemphys/reviews/u7review/u7ans3.html
24. ## calculating distance between two postcodes

You need to calculate the angle between those two lines (center earth to travelpoint) then multiply the earth radios with that angle (in rad). edit: http://pollux.nss.nima.mil/calc/calc_options.html#Distance%20Calculator some code: http://www.freevbcode.com/ShowCode.asp?ID=1793
25. ## So were did we NOT find organic molecules?

Also organic molecules in comet http://www.newscientistspace.com/article.ns?id=dn7961 http://astrobiology.arc.nasa.gov/news/expandnews.cfm?id=597 So I'm starting to wonder from all the places we looked for (if I'm correct) then it was only the moon that didn't have organic molecules (and that is probably because we didn't look good enough.) Aren't we getting in a situation that we will assume that there are organic molecules everywhere. (almost hard to find a place without some) Maybe in a few decates we will find out that there are all kind of small lifeforms everywhere.
