Fixed that for you. :wink: -
Rrenormalize reacted to PeterDonis's post in the thread Graduate How valid is the Block Universe theory? with
Like.
@DarkloidNeos the article you reference, unfortunately, is not just presenting the speculations or opinions of various physicists it... -
Rrenormalize replied to the thread High School Deflection of Light by the Sun.Can you better describe the points you're asking about by making reference to the diagram below? (from Shadow of the Moon and general...
-
Rrenormalize replied to the thread Undergrad How many carriers for phased array?.But how much effort have you expended to understand and appreciate the already existing technology? For example, it took me less than a...
-
Rrenormalize replied to the thread High School Example of a model for a function.I'm unaware of practical examples of your function:$$f_{k}\left(x\right)\equiv x^{k/x}$$but a transformation of that...

Rrenormalize reacted to PeterDonis's post in the thread Undergrad Is Gravi-GUT a candidate theory of everything? with
Like.
After some cleanup, the thread is reopened. -
Rrenormalize replied to the thread Undergrad How many carriers for phased array?.Perhaps you can gain intuition regarding the kind of beams that can be formed from a phased array of antennas by playing with on-line...

Rrenormalize replied to the thread I can no longer render LaTeX.Spectacular results! I no longer even have to refresh the page occasionally, as I used to, to get proper previewing. Kudos to Greg.
-
Rok it's back and now ## and $$ work in preview mode, also preview works with conversations
-
Rrenormalize replied to the thread Paradox in Induced Dipole Forces: Does it violate Newton's Third Law?.In Physics Forums you should use ## to wrap in-line LaTeX equations and $$ to wrap display equations. I've reformatted your post below...

Rrenormalize reacted to anuttarasammyak's post in the thread Undergrad Mixed approximation vs. full approximation for a power series expansion with
Like.
By the equations of post #4 $$x(0)=1-\frac{h(0)}{f(0)}=0$$ so $$(c_3+c_5)f(0)=c_1c_2$$ Is that correct ? We do not have freedom of... -
Rrenormalize replied to the thread Undergrad Why is a Gaussian function used to represent a wave packet?.Yes, the spreading of single-atom wave packets has been observed experimentally and agrees with theory: In-situ Imaging of a Single-Atom...

RHS of (1) would be g which is made of f and t. -
Rrenormalize replied to the thread Undergrad Mixed approximation vs. full approximation for a power series expansion.I don't see a function "##g##" defined anywhere in those lines.
-
Rrenormalize replied to the thread Undergrad Why is gravity a fictitious force?.That's of course a good point. But what empirical evidence exists that demonstrates that we don't really live in ##R^4\,##? It's been...
