    Gravity force = actio
    Inertial force = re-actio
    That's all.
    That's Izaak Newton

  • The Theory of Everything, Physics   6 days 8 hours ago

    Sometimes a dose of humor helps bring home a point.

    I guess it failed here.

    Apparently, you still don't understand that c^2 has units of length^2/time^2, which is not a velocity. And c^2 is not 186,000 times c. It is 186,000 mi/sec times c -- very different when the units are included.

    You speak of "the observation that energy is constantly consumed in the maintenance of matter." Who observed that?

    Did you ever hear of the law of conservation of mass/energy? You don't need to consume energy to maintain mass, but you can consume energy to create mass. Again, very different. And someone already explained the conversion between mass and energy. His name was Einstein, and he understood the importance of keeping dimensions straight in his equations.

    I apologize for trying to teach someone a bit of physics, especially when the claim is so immodest: a theory of everything.

    I'm outta here!

    What's "centrifugal force" got to do with this discussion?

    You seem to be denying Newton here. His third law notes that forces exist in pairs, where each body exerts a force on the other. Those forces are equal in magnitude and opposite in direction.

    So what body exerts a centrifugal force on the planets, and what is the corresponding force that the planets exert on that body?

    And more important: why do you need centrifugal force to explain orbital motion, which experimentally fits the hypothesis that gravity is the only force between the central body and its satellite?

    It seems I responded seriously to a purveyor of nonsense. Sorry, everyone!

    Perusaded by the evidence in support of Newton's laws, though the second law needs to be written F=dp/dt to be consistent with Relativity

  • Restore rights to ex-felons   6 days 9 hours ago

    Actually in the state of Washington, as long as your restitution is paid, and you do not own any fines then Felons CAN vote. I just found this out about a month ago when flipping through the Voter's Pamphlet. Not believing what I was reading, I called the Cowlitz County Elections office, to verify, and sure enough, We can vote... I suggest we try to make a difference. By the way, I too was convicted for a felony when I was 16 yrs old, over 13 yrs ago. I have since held the office of public servant by being a Volunteer Firefighter WHILE I was on Post Prison Supervision. I told them of my conviction, they contacted my Corrections Officer, and my Treatment group, and gave me a chance that I doubt any other Dept would give. Unfortunately I moved out of district due to family reasons so I am no longer a Volly, but maybe someday. I am in the middle of corresponding with a Washington State Representative to get some laws passed/changed that will better serve felons who have been convicted ONCE and have sense made the changes needed to live a successful life. I will keep anyone posted if they would like.... My email address is RT_Hauling@Yahoo.com

    My theory does not hang on a paticular velocity. I only speculate on this.
    The theory is based on the observation that energy is constantly consumed in the maintnance of matter. And that it posits a means for the delevery of this energy.
    My theory further conjectures on the ease with which it explains the other phenoma of the universe including gravity and Brownian motion. You may have missed this.
    Does a lame joke become funny if repeated? Try again.

  • Parrot understands concept of zero   6 days 10 hours ago

    The only thing that Leigh Roth of "Casa Leigh y Loros" and "Zihuatanejo Rentals" is is certifiably CRAZY and DEPRAVED. She purchases parrots illegally and literally neglects them to death. Rebeca Payne saved one of the macaws that had to be taken away from her and it now lives in a wildlife refuge since it cannot live on its own. I cared for one of her birds while she was out of the country for the best part of a year, and the day after I returned the parrot to her it was left unwatched on a chair at a restaurant where a dog attacked and killed it.

    Regarding the research, it is an unrealistic leap leap of reason to say a parrot living in confinement all its life understands the "concept of zero" because it allegedly identified an empty food tray. Empty food trays and mathematical concepts of zero are as different as lighting and the lightning bug.

    Sincerely,

  • Infrared photographs of Uranus taken by HST in 1994-2003 and by Voyager2 1986   6 days 11 hours ago

    The fundamental error of the contemporary celestial mechanics is the mathematically prohibited transformation of the reference frames that leads many physicists to a conclusion that in the orbital motion the only force acting on a planet is the gravity force and that the centrifugal force does not exist.
    Each true non-homogenous body during every rotation becomes a centrifuge which means that the so called weightlessness state on the orbit is only an approximation (with the exclusion of density differences). A proof for that are the phenomena observed at the ISS, which are erroneously called a microgravity. In reality they are differences of the orbital centrifugal force caused by differences in densities of particular parts of the station. The proof for that every planet on the orbit around the Sun acts exactly as an ordinary centrifuge are the infrared photographs of Uranus taken in 1994÷2003.
    As it results from the above given arguments the theorem stating that the only force acting on a body in orbital motion is the gravity force is fundamentally erroneous. The orbital centrifugal force results directly from the principle of momentum conservation as a vector value and is inseparably connected with the centripetal force. Therefore a fundamental error is a statement that the Earth, Moon or any space object are in freefall in their orbital motion. Therefore both the concept Free Fall and the Universality of Free Fall (UFF) are myths that need to be rejected by physics as they block further development of geophysics and astronomy.

  • A Smile Really Is Contagious   6 days 12 hours ago

    It would have been nice to have a reference to the original study so we could read more about the psychology of smiling. I have a student looking for information about whether or not smiling is contageous...this would have been a big help!

  • Old men chasing young women: A good thing   6 days 13 hours ago

    This is such a thought provoking thread. I had recently viewed a video with Larry King ( I love and respect Larry as a talk show host ) playing with his very adorable toddler boys. It was absolutlely pitiful to watch that very fragile, hunched over old man attempting to play with and keep up with his very active children. On the other hand I watched my son-in-law roughhouse with his two young children just this past weekend. His young ,strong virile body easily tossing the children over his head with them laughing with glee! What a beautiful sight! Ahhh I must say every fiber in my body KNOWS that nature intended the young and the strong to reproduce, it is truly poetry in motion.

  • Study reveals marriage dowry as major cause of poverty in Bangladesh   6 days 15 hours ago

    so in that case , the more sons you will be having the richer you will be? Now tell me , Is it then right to say that the riches iperson in bangladesh is someone who has huge number of sons?

  • The oldest language   6 days 22 hours ago

    Some people try to march back as the truth approaches towards them........It's not the matter of miscommunication, or the oldest language in this world which people are trying to express here........ofcourse, we all have the truth within,but most of us are not ready to accept...........We need to prepare ourselves for a better life, not to degrade anyone in rush of proving individual greatness......

    Concept of oldest language itself is a nonsense.............

    Every tiger will say I am the only king but unfortunately, none of them know the reality.........

  • The oldest language   6 days 22 hours ago

    Proven fact ay!!! and who has proved it??? some dumb and unaware person of the western world??? there is nothing wrong in being proud of the culture... sanskrit is the mother of ALL languages in the world. It is a hard fact to accept. You won't I know . Why would the western world take this from the most gifted people right! INDIANS HAVE BRAINS. They are amongst highest rankings in army, scientists, doctors, engineers, technicians, IT professionals. You name it-- you see them standing right at the top. So they cant be dumb. Well if you dont want to accept the sanskrit is mother of all languages, I would re-phrase it for you. Sanskrit is the oldest language and the creater or most languages in the world (not only india).

  • Old men chasing young women: A good thing   1 week 1 hour ago

    HI I WOULD LIKE FOR YOU TO KNOW THAT YOUR COMPLETELY RIGHT IN THIS SITUATION. I AM IN THE SAME SITUATION AS YOU. I AM 18 YEARS OLD IN COLLEGE TO BECOME A ELEMENTARY SCHOOL TEACHER AND I AM DATING A OLDER MEN. HE IS IN HIS 40'S. I LOVE HIM SO MUCH AND HE LOVES ME. WE DONT CARE ABOUT OUR AGE DIFFERENCE. I DO GET ALOT OF CRITICISM AS WELL, I HAVENT TOLD MY PARENTS YET. I JUST MET HIS PARENTS AND THEY LOVE ME, EVEN IF THEY ARE IN THEIR LATE 80'S AND EARLY 90'S. HIS PARENTS SAY THAT WE SHOULD GO FOR IT AND EVEN HAVE A BABY! CAN YOU BELIEVE IT! I DONT THINK THEY ARE READY TO KNOW. MY BOYFRIEND HAS 3 KIDS FROM HIS PREVIOUS MARRIAGE AND IT IS SOOO HARD BECAUSE THEY ARE ALL IN THEIR TEEN YEARS. YES, THEY KNOW THAT I AM DATING THEIR DAD AND THEY ARE HAVING A TOUGH TIME WITH IT. I AM GETTING A CLOSER RELATIONSHIP WITH HIS MIDDLE DAUGHTER THAT IS 14 YEARS OLD. I AM HOPING THAT ME AND HIS DAUGHTER WILL START HANGING OUT SOON AND THEN I HAVE TO FIND SOMEWAY TO GET HIS SON AND OTHER DAUGHTER TO APPROVE. ME AND MY BOYFRIEND WANT TO GET MARRIED AFTER I GRADUATE AND HE WANTS TO BE THE FATHER TO MY KIDS. CAN ANYONE ELSE GIVE ME ADVICE. I REALLY NEED IT! THANKS

    First of all, india is not the one producing the terrorists, its pakistan and Afghanistan. And the only reason they are terrorists is because of big stupid Americans, who drive pickup trucks and think they can afford to buy a 60 inch tv when they are defaulting on several mortgage payments. Im going to go ahead and assume that you fall under this category. The reason you dont give a shit is because you cant. You lack the capacity. Your comments, short in nature and seemingly to the point only affirm the stereotype that has been building across the world, that Americans are stupid.
    And even if youre not American, i would look on that as even more of a failure on your part that you have no idea what is going on in the Eastern hemisphere. Well i suppose if your headline news involves the saving a small cat and how the heroic fireman climbed the tree, then i wouldnt know either. but then again int hat situation i wouldnt attempt to comment on something i have absolutely no idea about. I guess in that case you would be one quiet little sad man with all the intellectual capacity of a small turnip. Anyway im not here to uncover facts about people so all i would advise you to do, is that before taking part in a conversation of some intellectual stimulation, give a shit, and you will see it makes a world of difference

    Well its obvious that most of the people in this thread are pseudo braniacs. The topic is not what Indian language is oldest but what is the oldest in the world in terms of spoken phonetically. The micro crisis that seems to arise here is that none of the people in this thread (including some people who are clearly white and perhaps even inbred) understand or write english very well. Now if youre going to comment on something someone has read, at least have the decency to check whether your comment is pertaining to the topic.
    And yes we all know Wikipedia and many indian sites exist where most of the information posted below is probably given so that it may be conveniently copy-pasted. And BTW im Indian.

  • Infrared photographs of Uranus taken by HST in 1994-2003 and by Voyager2 1986   1 week 4 hours ago

    If it was the Sun that warmed the planet so irregularly, then the warmer zone would always be turned towards the Sun.

    The warmest weather on Earth lags the solstice by about six weeks, so that statement doesn't seem correct. We would expect an asymmetry, though the asymmetry would shift from one side of the equator to the other.

    On Uranus, the conditions are even more extreme due to its 98-degree tilt. During the years of those photos, Uranus was nearing Equinox, which it reached in late 2007. In other words, they were all taken during the same season, and you would expect an asymmetry to remain about the same during such a short period of the 84-year Uranian orbit.

    Many of those photos would be credited to Heidi Hammel. clicking her name will take you to the website about her biography, Beyond Jupiter, which I wrote in 2005.

  • Spearmint tea -- A possible treatment for hairy women   1 week 7 hours ago

    heyy i dident no that there were other people with the same problem. I have hair practically everywhere and i get really depressed about it. none of my friends know and i try to keep it that was because i would just hate it if people made fun of me because of it. i get some of the hair on my body waxed but it just come back within 3 or something days. i dont go swimming or anything with my friends because i just get really depressed and worried what other people think of me. I was going to get laser treatment but its to expensive. hopefully the tea works fingers crossed. Im 13 by the way x.
