donnaeadv Posted November 21, 2009 Posted November 21, 2009 Hi everybody, My name is Donna, I am 41 yrs old, living in Debrecen, AZ. I'd love to make good close friends here. Thanks, Donna.
bsvineeth2009 Posted November 21, 2009 Posted November 21, 2009 Hi everyone. My name is Vineeth . Iam too Science holic. We can share our discoveries with us and become good friends. I love u all my dear friennds!!! Merged post follows: Consecutive posts mergedI have a doubt. ' I will present my hypothesis will u express ur opinions? Please Analyse my calculations...pls.. Force of Influence between energies: According to the Universal Gravitational Law by Newton, any two bodies of masses ‘m1‘ and ‘m2‘ separated by a distance ‘r’ have a Force of Attraction(Fm) given by: Fm = G. (m1 m2)/r2 --- (1) If there are two charges each ‘q1’ and ‘q2’ separated by a distance ‘r’ then the force of attraction or repulsion between the two charges in free space is: Fc = (4 0)-1. (q1q2/r2) --- (2) There is attraction force between two masses, and we also know that mass and energy are inter-related and also charge is a kind of energy. So there must be some Force of Influence (Fe) between any two energies of different kind. Let us consider two point concentrated energies E1 and E2 of different kinds or of the same kind. All the energy obtained to us is mainly from Sun. In fact, the energy in the space is also due to conversion of some celestial mass. Therefore in this context, Albert Einstein’s Mass-Energy Equivalence Relation is applicable. So any energy in the universe corresponds to some mass which has been converted into energy by some nuclear reaction. So by Einstein’s Equation: E = m. c2 m = E/c2 --- (3) On substituting ‘m1’, ‘m2’ in equation (1) by ‘m’ in equation (3), then we get; Fe= (G/c4). (E1 E2/r2) --- (4) Let the constant here (i.e. G/c4) obtained be named as Constant of Influence represented by . On substituting the values of G and c in the constant obtained, = G/c4 8.22222 x 10-45 Nm2/J2. So, in the equation (4), if E1 = 1J, E2 = 1J and r = 1m then the equation becomes: Fe = 8.22222 x 10-45 N So, this means that if there are two point concentrated energies (assuming that they are at rest) each of 1J separated by a distance of 1m then the force (of attraction or influence) is approx. 8.22222 x 10-45 N between them. Let these energies move at velocities v1, v2 and let their Lorentz’s Factors be: γ1, γ2. Then γ1= (1-(v12/c2))-1/2 and γ2= (1-(v22/c2))-1/2. Then; Fe= (G/c4). (E1 / γ1 ).(E2/ γ2).(1/ r2 ) --- (5) ----------------------------------------------------------------------------------------------------------By Vineeth-------------

michel123456 Posted November 28, 2009 Posted November 28, 2009 Hi. I am Michel. Male (for disambiguation). Coming from the collapse of another forum. Learning everyday.
hoatra Posted November 30, 2009 Posted November 30, 2009 (edited) Hi I'm Skye and I'm amused by puffer fish. Mainly because I caught some the other day that were in little sand pools. How? By herding them onto the sand. Yes, they swam onto the sand. Fish. Swimming onto land. Not only that, but they then puffed themself up so they were even more screwed. I'm wondering whether it has anything to do with their tiny genomes. That, and just laughing my arse off at them. Welcome to this site and I am also newbie here. My name is Disoza and I have just recently join this site. I am here to interact with people and definitely get the information regarding experiencefestival community. Glad to join this site.

drertanna Posted December 3, 2009 Posted December 3, 2009 Howdy, I'm new to this community & just thought it would be a good idea to introduce myself and say "howdy". Finally a solid community with active people that I can read - which truly is a refreshing change! I'm here to learn @ participate. How would I best participate? Bye For Now~
npts2020 Posted December 3, 2009 Posted December 3, 2009 Welcome all, it is always good to have new people interested enough in science to bother signing up to participate at this site. Learning about and teaching science is what this site is all about and I don't think it is too much of a stretch to say that everyone who is here for long does some of each.
jimramos11 Posted December 6, 2009 Posted December 6, 2009 Hello all! I'm a nursing student and biology has been an interest to me. I hope I can meet new friends here in my new community.
Mr Black Posted December 6, 2009 Posted December 6, 2009 hi everyone, I like martial arts, science and computers. and i hope to learn a lot here
th3roman Posted December 7, 2009 Posted December 7, 2009 Hey its th3roman here, just registered. Have a huge interest in mathematics and the sciences. I wanna ask, what are the subjects that I need to learn and understand to be able to read and understand mathematics, engineering and sciences like astronomy. What subjects I mean by are the principle areas that I have to know before being able to do mathematics and sciences at a technical level. Understanding formulas and such. It'd be a great help if someone points me to the right direction. Thanks
toastywombel Posted December 7, 2009 Posted December 7, 2009 Hmm. . . I have been a member for a couple months now and have made a plethora of posts, but I never noticed there was an introduce yourself page. . . Well I guess better late than never. My name is James aka: toastywombel. I am 20 years old. I fancy reading, programming, computing, physics, mathematics, engineering (I still play with legos yes), and music (I play guitar, piano, and a mean triangle ). I would consider myself the underachiever that every girl wants to sleep with, minus the every girl thing and them wanting to sleep with me thing . I graduated high school with a 4.0 GPA. I work at two part-time jobs, and am currently attending college. My current major is liberal arts but that major is really just an unknown variable which I plan to replace with something a little more respectable. I am very unsure of what I want from college and life itself. This is a science forum though, not an online therapist's office so this will have to conclude this brief synopsis of my existence.
A Tripolation Posted December 7, 2009 Posted December 7, 2009 Hmm. . . I fancy reading, programming, computing, physics, mathematics, engineering (I still play with legos yes), and music I tip my hat to anyone who recognizes that legos are the highest feat of engineering ever accomplished. Well done, sir.
realett Posted December 8, 2009 Posted December 8, 2009 Hi. I love planetary motion and the study of curvature. I'm also hoping to run into some discussions on differential geometry. Furthermore, I'm looking for potential authors to write for a science press. So, if any of you read this and are looking for a publisher, please write me or visit http://www.perfscipress.com. --Thomas
thegdin Posted December 10, 2009 Posted December 10, 2009 Hello all. im here to build my knowledge as i feel learning should never end. at least until you know everything. (and im getting so close. kidding)
vordhosbn Posted December 11, 2009 Posted December 11, 2009 Hello, i've been lurking these forums for some time now, and finaly decided to join the discussions.

mickelmass Posted December 19, 2009 Posted December 19, 2009 Hi My name is Mike and I have no idea whatsoever why I even joined this forum?
wolfgangXaxt Posted December 24, 2009 Posted December 24, 2009 Hello, I have a question: Regarding how much of the celestial sky is visible from any point on earth... Everything I see and hear say's it is 180 degrees, which, makes sense to me. But, I backpack with a crew that (some) says otherwise (every time we are out staring at the sky). I need some help. Is this correct? Here is how the argument starts: 1. we can see more than 180 degrees from our position (or any position on the earth) of the celestail sky above.Some argue that we cannot. Some of the lads say we can. 2. A satellite passes over head, some say the satellite is visible more than 180 degrees i.e., if the satellite orbit is elliptical and very high, it could be visible more than 180 degrees. So, what I have described above is the essence of every debate that we all endure (affectionately) on each of our outings. Please help. thank you, michael n
Zolar V Posted December 24, 2009 Posted December 24, 2009 Huh, i dont think i ever actually introduced myself, all that 1 year ago. My name is Michael and i now work in the usaf. The easiest way to describe my personality and thougths through out a day is 'visionairy'. completely unrealistic visionairy. I absolutely love learning new things, in the fields of Science and History, not so much english as words dont fully convey meaning due to their lack of color.
Dawhapwandy Posted December 25, 2009 Posted December 25, 2009 Hi Guys, Just stumbled upon this site. It looks cool and I think I will be having a good time over here. Welcome me
