My friend's son (age 5) absolutely loves space. It's great to see such a strong interest in science in kids that age. He calls me the astronaut guy since I told him I've wanted to be an astronaut since I was a kid, and that I also love space. We recently shared a discussion about the planets...
Bear in mind that an exact equation accounts for all possible factors. In your example, how an object falls in a gravitational field, the equation we use for this motion only accounts for four factors: the initial height in some reference frame, as well as initial velocity, the strength of the...
For quite some time now, I have had a very fundamental question about Nature and how we perceive Her. More specifically, I have had a very fundamental question about the tool we use to investigate Nature. There seems to be only one valid way of understanding how the world works, and that is...
Thanks! And so for the probability that at most one red ball is picked:
"at most one" means either 0 red balls are picked or 1 red ball is picked.
If no red balls are picked, then:
P(not red)*P(not red)*P(not red)= (14/16)(13/15)(12/14)= 13/20
and if one red ball is picked it can happen three...
Probability of "exactly one" when events are dependent
The question is this:
"An urn is filled with 8 green balls, 2 red balls, and 6 orange balls. Three balls are selected without replacement."
What is the probability that exactly one ball is orange?
I know I could just use the binomial...
Thank you everyone for all the responses so far! I've looked more into Schwartz's book, and I think I will really like it. Do you think Taylor's book is geared solely for undergraduates, or would it prepare me for some beginning graduate level mechanics problems? At this point I'm still...
I may go with Goldstein for classical mechanics, as I just read on the Amazon description "..Mathematical techniques are presented in detail so that the book remains fully accessible to readers who have not had an intermediate course in classical mechanics." This statement appeals to me since I...
Hello all,
First, to tell you a little about my background, I have just finished my undergraduate degree in geology and geophysics. I also attained two minors in astronomy and mathematics. Thus, my physics and math background includes a year of freshman physics (mechanics & E&M) plus a...
