PART OF ORIGINAL FLANGE APPARENTLY BROKE OFF AND THE PLUMBERS DIDN'T BOTHER TO. REPLACE IT. THIS HAPPENED AT THE TIME THE HOUSE WAS BUILT. WHEN THE HARDWOOD. FLOOR PERSON PULLED THE TOILET, IT WAS MOIST. WE ARE GOING TO NEED A NEW. FLANGE AND HAVE THE TOILET RESET. I NEED TO KNOW HOW MUCH A JOB LIKE THIS COSTS.
Important four-vectors include the position four-vector and momentum four-vector. Special relativity is a theory proposed by Albert Einstein that describes the propagation of matter and light at high speeds.
What causes Gravity? One of Einstein's old tutors, a man by the name of Minkowski showed that the special theory of relativity could be expressed in an interesting way. The world we live in consists of four dimensions, the three space dimensions and one that is not exactly time but is related to time (it is in fact time multiplied by the square root of -1). This is not at all easy to understand but it means that space-time as we call it has some rather weird properties.
