Wow I must have been too tired when I did that -- got the wrong expansion and couldn't even copy it right either.  Thanks for correcting! :)

Of course! :) Going back to hemineglect: here are a couple good videos about it with some interviews of patients with the syndrome.  The demonstration where the interviewer asks which finger he moves is remarkable.  It is not as simple as a problem of vision, it's a problem of how the mind thinks ab...

^I like it. :)

Here's a rather surreal mix of music and the dark age of American nuclear testing.

Science and Astronomy Questions

Ah, I see.  And I found that there is in fact a linear combination of functions that will work: T he series expansion x^2/2 + x^4/4 + x^6/8 + x^8/16 + ... will approximate the curvature of the circle.  And t he function x^(very large even number) is virtually flat between -1 and 1 but very steep out...

I think it would have to be defined piece-wise, because the derivatives (slopes) are not continuous -- they change discontinuously when you go from the half-circle part to the straighter and more vertical sides.  The half-circle part can be described by y=-sqrt(r^2 - x^2) + r, where r is the radius ...

6509 Hemineglect? Never heard of it- but just breaking down the term, does it have to do with some senses atrophying because we don't use them as much when we get older?  Just a shot in the dark lol. No, it's way weirder, and usually is a result of damage to the brain.  A person with hemineglect &q...

Minor nitpick, but it would be very nearly a full moon, not a quarter moon (easier to see if diagram is to scale).

Also if a solar-intensity laser should strike Earth, I advise not looking directly into the beam.

e69XZJ9DEj0 An amazing examination of a curious and mostly harmless genetic mutation. 6833 Maybe I am wrong, but from what I understand of the physics and of probability, it seems more likely that the physical interactions would be more likely to start a universe over a brain in a void. I'm really ...

Totally off-topic thread

Looks like I may have an opportunity to do astrophysics research over this summer, using visible and x-ray observations of galactic clusters to help test the Lambda-CDM model of cosmology.  Neat!

The knowledge that the head of a Prince Ruperts drop is strong will not prepare you for how ridiculous this footage is.

And on a wholly unrelated topic, Space-Time tackles the statistical thermodynamic oddity of Boltzman Brains.  Also, Firefly references.

6824 What I would ask though is if the statements of some astronauts, particularly the Apollo astronuts, does not raise doubts about just what is visible out there? None whatsoever. :)   And by your own admission, you are unable to justify your doubt or your claims, and your hypothesis has been fou...

The paper looks legit.  Not really my area and not sure if the implications are being overblown, but it does sound promising!

6810 That's very interesting Watsisname  I didn't realized that. Yeah, Compton scattering is pretty neat and important in a number of astrophysical situations.  You can think of it as the photons and electrons colliding and rebounding off each other like billiard balls, exchanging energy and moment...
