Thank you for the answer. :smile:
Can you please explain how quantum fluctuations affected the distribution of matter? (I assume you were referring to the distribution of mass in space with your use of the phrase "...different densities in different regions...")
I watched a video on the Youtube channel Kurzgesagt titled How far can we go? Limits of humanity
The video attempts to explain why we may be limited to our local galaxy group even with science fiction technologies.
During a part of the video (starting at 2:26), they try to explain how...
So any small, one man projects/hacks or anything that I might be able to work on and learn through experience?
So far I have studied the following courses that might be somewhat directly applicable (other than the basic sciences and math):
1. Programming (OOP and basic Data structures and...
I am an undergrad EE student at the end of my fourth semester. I have to take a couple of courses in the summer semester to improve them. So a full time internship might not be possible.
Are there any small things I can learn along the way in the summer, on my own?
Any new software...
What is the "wait" operation? Staying in the same state if the inputs from the IR receivers remain unchanged? Or is it something more complicated?
For the sequence detector to wait if nothing changes is exactly what I think I need.
What I meant to say was that each sequence detector would be looking for a particular sequence.
One sequence detector would output '1' for incrementing the counter when the input sequence for entering is detected. (lets say it would be 00->01->11->10->00), while the other does the opposite for...
Hello. We have been given a project in our course "Digital Logic Design", which is an introductory course to Digital Logic. We are only allowed to use gates, multiplexers, flip-flops/latches, counters, comparators, simple displays (like seven segments) etc.
I am making...
I went through someone's thread asking regarding a popular science book, a considerable time ago. I got the impression that the more knowledgeable members in the discussion did not approve of most popular science books (if my memory serves me right the point mainly was that it gave people the...
Good one. Sort of inspirational. Can relate myself to more than one part. Was confused between physics and EE (although my physics never was very good). Now doing EE and the first year so far (in 2nd semester) has been very bad. Hope I can pull it off nicely from here onward like berkeman did. :)
According to the eq. U=mgh the gravitational potential energy should keep increasing with height. But it actually reaches zero at infinity.
At what point does the g.p energy start decreasing when going away from earth?
Why does this eq. seem to contradict -GMm/r where g.p energy decreases with...
Just a couple of questions to clear it up. When all the three possibilities were tried, how should I have known that the answer I got by y-4<0 one of the two intervals?
And can I find the second interval that I had found in my original solution using this method?
y-4 = 0 => y=4
y-4 > 0 => y>4
y-4 < 0 => y<4?
Still I don't get you. I take the three different possible cases. What do I do with them? Do I have to check each to see which are correct? Or somehow use them to get y ≤ 0?
The following equation defines a rational function.Find its Range
f(x) = x2/(x-1)
The attempt at a solution
Let y = x2/(x-1)
=>y(x-1) = x2
=>xy-y = x2
=>x2-xy+y = 0
comparing with the general form of quadratic equation ax2+bx+c = 0,
a=1, b=-y, c=y...
I have the fifth edition of 'Physics' by Halliday, Resnick and Krane.
In the chapter 'The Nature of Light' it is stated that it is possible to explain both photoelectric effect and Compton effect in classical electromagnetic wave theory and this has been known since 1927. It says that...
Our physics textbooks have had errors in the past. The whole time dilation section appears wrong to me now except for the rearranged equation you explained. Thanks for clearing it up. You helped me a lot.
So for example if Ted's clocks measure 10 seconds, as Alice moved between those two clocks, he will see Alice's clock to have measured e.g 4, 5 or 6 seconds.(I mean less than his 10s).
But the equation in my textbook is
t = to/√(1-v2/c2)
Where to is the...
Another small confusion/question related to time dilation which I think doesn't need a thread of its own. :smile:
When we say a moving clock ticks slower, does it mean it will count less number of seconds than a stationary clock? e.g 5s in my stationary clock , I'll observe less than 5s in a...
