test 1 study guide phys107, quinn chapter 1: about science what is science?  a body of knowledge and a way of thinking that describes the order within the natural world and the causes of that order o ideas are organized based on observation o modern science (since the 1500s) expresses those ideas with mathematics, because it’s unambiguous and easy to verify/disprove  disclaimer: science has never proven one thing; instead, many hypotheses have been tested over and over and some have had a constant result, many have not. the only thing science can do is
the sun fuses hydrogen to helium in an atomic reaction similar to a hydrogen bomb, this reaction gives off energy and hence provides us with a lot radiant energy, most astronomers believe that the sun has been “turned on” for about 4.5 billion years. 

as the sun gets older, it will continue to fuse hydrogen in its core, scientists estimate that there is enough hydrogen fuel to continue this process for another 4 billion years or so, then the fun starts….

once the majority of the sun’s hydrogen is turned into helium, it stops fusing hydrogen and loses its ability to combat gravity, the sun will begin to compress under its own weight. the higher pressures and temperatures at the sun’s core will cause helium to begin to fuse into carbon in a similar process to the hydrogen fusion, this too balances out the gravity and the sun will continue to shine, but the process of fusing helium gives off more energy than the fusing of hydrogen. this additional energy streaming out of the core radiates through the “envelope”, the layers outside the core. this very high energy into the envelope heats up the envelope causing the envelope expand greatly to hundreds of times its original size. 

the part that can be seen (the envelope) is much cooler than the young sun was and it is red in color, the sun has become a red giant star. 

even though the red envelope is cooler than the young sun it is still very hot, about 5000° fahrenheit! unfortunately, for any life on planets in the inner solar system, the red giant sun's envelope will expand to engulf all the way out past earth and mars. all the oceans will be evaporated away and in fact the earth's atmosphere will be blown into space. the engulfed planets will, obivously, be uninhabitable. the rhythmic rise and fall of ocean water twice a day is called a tide. tides are caused due to the gravitational pull exerted by the sun and the moon on the earth’s surface. kindly refer the following link for similar query

have a look at his chart at astrodatabank, where his *accurate* data is offered from his verified birth certificate, aa according to the rodden ratings. you'll also find a nice bio on him there:

astrodatabank was the brainchild of lois rodden, who was considered the queen of accurate data. she demanded accurate data and set the standards through which astrologers now aim to achieve their focus today. sloppy astrology includes inaccurate data, inaccurate calculation, and a lack of verifiable data.

i hope this gives you some help in seeing the process through which we work. especially in a world where some think we aren't focused on precision or accuracy, the need to stress these things is critically important. the most direct test is to measure pressure in the spinal fluid. this is done with a spinal tap and pressure measuring column. the fluid column is measured, and then the fluid is drained off. just draining the fluid can relieve symptoms. analysis of the fluid would rule out more serious conditions. this procedure is easily performed in a doctor's office or emergency room. see more... a bob of mass m is suspended by inextensible string of length l from a fixed point. the bob is given a speed of at the bottom point. find the tension in the string when string deflects through an angle 120 degree from vertical.
