FactChecker's latest activity
-
FactChecker replied to the thread I Can this experiment break Lorentz symmetry?.That's a good question, but I don't see a difference between this and many experiments that have already been done. Accelerating... -
FactChecker reacted to .Scott's post in the thread I Could fast radio bursts be alien radar signals? with
Like.
There are a lot of reasons to doubt that FRBs are deliberately engineered and fabricated. But their application for radar is especially... -
FactChecker reacted to PeroK's post in the thread Finding the nth roots of a complex number with Like.
1.41 is an approximation for ##\sqrt 2##

FactChecker replied to the thread Finding the nth roots of a complex number.Right, no real root. What roots are you getting? Are you sure they aren't correct? Sorry, I see your answers in post #1...
-
FactChecker replied to the thread Finding the nth roots of a complex number.That is correct. There are only n values (k=0,1,...,n-1). Your assumption that there is always a real root is wrong. If there is a real...

FactChecker replied to the thread Learning data structures and algorithms in different programming languages.Wow! That sounds like a mind boggling task! My hat's off to you!

FactChecker reacted to .Scott's post in the thread Learning data structures and algorithms in different programming languages with Like.
In reading Codd's original work, wiki articles, and quite a few more recent articles, I see very good technical descriptions of what a...

FactChecker reacted to Iskandarani's post in the thread A Is the constancy of c a postulate or a derivable theorem? with Like.
Thank you, @Ibix. That is an incredibly helpful and concise answer. Giving me the precise term "Lorentz Ether Theory" is exactly what I...

FactChecker reacted to Ibix's post in the thread A Is the constancy of c a postulate or a derivable theorem? with Like.
You can add an undetectable preferred foliation - it's called Lorentz ether theory. It's just SR with the claim that one frame is...

FactChecker replied to the thread Documentation of (only) source code.I am not familiar with that book. There might be a more modern one now. I wouldn't expect exact questions from any text, but I haven't...

FactChecker replied to the thread Learning data structures and algorithms in different programming languages.@.Scott , That's a very good point. One treacherous thing about data bases is that the need for normalization may not be obvious until a...

FactChecker reacted to .Scott's post in the thread Learning data structures and algorithms in different programming languages with Like.
Regardless of what language you use to implement your data structures, I suggest you brief yourself on database normalization. The one...

FactChecker replied to the thread I Understanding the historical shift away from absolute simultaneity.In general, you should separate the goals of clear understanding of physics versus knowing the history. There were many confused people...
-
FactChecker replied to the thread Documentation of (only) source code.IMO, there is no official definition of where "pseudocode" ends and good comments begin. Books and academic discussions about algorithms...

FactChecker replied to the thread When should a beginner programmer learn vims/emacs?.One reason we remember the keyboard shortcuts is that they are quick, easy, and you don't have to keep moving a hand from the keyboard...
