We here all about the Voyager probe that is now heading out of the solar system but what about the other one? 2 were sent into space at the same time, they both used Jupiter (I think) as a sling shot and one headed towards Neptune etc and is the most publicised one. What about the other, do we still recieve signals from that?

In vectors, if a.b= 0, then either a or b is the zero vector or they are perpendicular. Why can't a and b be both zero vectors to make a.b=0? Why must it be either??
a and b are vectors.

Please explain clearly!

My grandfather, age 73 has had trouble with his hip for several years. he had it replaced last week. He was previously taking morphine 45mg, 3 times a day. The hosp had down that he was taking 15mg 3 times a day, so they did not give him enough pain meds in recovery. My mom and I tried to tell them he was in too much pain, and told them what he was taking, the nurses were very nice first but then later on they were almost arguing with us, then they suddenly realized they had made a mistake, quickly walked away from us, went over to the nurses station, talked very quietly for about 5 minutes with their backs to us, paged the doctor,then one nurse came over, and adjusted his pain drip. It looked to me as if they made a mistake and tried to cover it up. My mom and I did not make a big deal about it. They were extra nice afterwards. How often does stuff like this happen? Do they just try to cover mistakes all the time? What if it had been his heart medicine???No wonder I hate doctors!!!
