Sir Isaac Newton was the first theoretical physicist, although in his own time his profession was called "natural philosophy".  By Newton's era people had already used algebra and geometry but algebra and geometry only describe things that are sitting still. In order to describe things that are moving or changing in some way, Newton invented calculus.  Newton's new calculus, combined with his "Laws of Motion", made a mathematical model for the force of gravity that not only described the observed motions of planets and stars in the night sky, but also of swinging weights and flying cannonballs in England.  Today's theoretical physicists are often working on the boundaries of known mathematics, sometimes inventing new mathematics as they need it, like Newton did with calculus.  The so-called "Newton's Laws of Motion" are not abstract laws that Nature is somehow forced to obey, but the observed behavior of Nature that is described through mathematics. In Newton's time, theory and experiment went together.  Today the functions of theory and observation are divided into two distinct communities in physics. Both experiments and theories are much more complex than back in Newton's time. Theorists are exploring areas of Nature in mathematics that technology so far does not allow us to observe in experiments. Today's theorists have to learn to live with ambiguity and uncertainty in their mission to describe Nature using math. The above passage is an attempt to adequately answer which of the following questions? OPTIONS     1) What is theoretical physics?   2) Why do physicists have to invent new mathematics all the time?   3) Are there more fundamental theories than the ones Newton discovered?   4) What are the current areas of research in physics? discuss | yesterday's solution | more questions Tip of the Day If (x + 4y) is divisible by 13 where y is the units place digit and x is the number obtained by removing the last digit, then the number is divisible by 13. more tips Last year's Question of the day (07-Jun-12) If all the roots of the equation x4 – 2ax2 + x + a2 – a = 0 are real then which of the following is definitely true?
