I was in my car driving, and it has been cloudy, cold, and snowy. Well, I just looked up at the clouds and I saw this little round light and it was bright, and like it was coming out of the bottom of the cloud, and as I was looking at it I thought, "was is that"? then it disappeared. Did anyone else see this? What do you think it was?

originally, i had wanted to major somewhere in astronomy but i noticed that i didn't really like the math that's involved with it. the concept of astronomy is amazing; i love it. however, it requires a great deal of physics and calculus which im not entirely sure i want to do for the rest of my life. i recently looked into marine biology, but have many questions about it. can an actual marine biologist tell me what's a typical day for him/her like and how much the career pays on average? any other information is appreciated! thanks!

since
a=mtbf/(mtbf + mtte)
we could determine that
mttr X a = mtbd(1-a)
can we simplify more than that
