you're hot, but you look like a tranny
-
anyone can tell me about best astrophysics college in delhi
-
Leave my wife alone, MFs!
-
Honey, please comment on the ever-so-sacred-to-some Brown Star

That's a man

How do you account for red or blue shift before determining a star's true color, thus the temperature thus the true radii?
-
Star SCHMAR! JESUS - you're gorgeous! And that cute Spanish accent. GRRRRRrrrr.
And the beautiful eyes. And hair. And face. And hands. And brains! Wow. -
Amazing. All that knowledge with a pen and math. Boggles the mind. Is your day job a Uni teacher? My lady teacher at little school carried a ruler and would beat me. .. Just saying.
-
How did you get the temperature directly from the BV magnitude? any fomulas?
-
H=iq(150)+(face)x(body) where h is her hotness level.Wow I normally can come up with some witty way of saying how bad or beautiful things are but Eylene Pirez left me speechless, she incredibly hot, wow I promised to myself to never marry again but for her I can change my mind
-
So you can't put an exact size to a star but you can get a comparison to the sun following this formula?
-
Thank you I learned something new, I really enjoy astrophysics!
-
pfft i learned this when i was 2 years old

To determine stellar surface temp... Stars are made mostly of hydrogen and helium. Nine out of ten atoms in the universe are hydrogen atoms. Nine out of ten of what's left is helium. So, when we check out the spectrum of a star, we should see mostly hydrogen and helium. We don't, and the reason comes from the atomic physics of the individual elements.

i just wonder if i f..k her i get scientist babies ,if this was true then was one woman enough for the all planet (that is the big mistake of the aliens ,they thought that we all were intelligent) 👽 ☼☾☄ ₪itibira₪∇∿✻☥∵∢▲▵▴

I think I enjoyed this presentation the best so far. It brought up a topic I had not encountered yet and I branched out and read up on color indexes (UBV photometry) and Wein's law as well. Have you any plans to do any more like this? I would like to see some on dynamical parallax and other binary star topics. Thanks!

Googled her- She works at UCLA
-
How does she write backwards? Right? :) She doesn't. The transparent board she is writing filmed normally, yet in post-production it is reversed to mirror image. So she is not left handed either :) Mystery solved .
-
Hit women can be physicists. Take for example, Dr Christmas Jones in 'The World is Not Enough'.
-
Wait, how is that marker and board working? She nots writing backwards is she?
