Are you surprised that John Christy thinks the 'missing hot spot' is due to a data error?
Q. An "Executive Summary" by the U.S. Climate Change Science Program, co-authored by John Christy of UAH concludes: "...discrepanci es in the tropics remain to be resolved. This difference between models and observations may arise from errors that are common to all models, from errors in the observational data sets, or from a combination of these factors. The second explanation is favored, but the issue is still open." Considering that Christy is a 'skeptic' and the 'missing hot spot' is an argument frequently made by deniers against AGW, does it surprise you that Christy thinks the discrepancy is likely due to satellite data errors?

A. Coming from Christy it doesn't. Maybe if Lindzen or Watts had said it it'd raise a few eyebrows, but Christy seems like a pretty honest guy. Integrity and honesty are qualities that are hard to find in the ever shrinking pool of climate skeptics.

derive the equation of the least squares fitted line?
Q. For n observational pairs (xi,yi), i=1,2,...,n it is required to fit a straight line y=a+bx by least squares. By minimising the error sum of squares S, given by n S = SIGMA (yi-a-bxi)^2 i=1 or otherwise, derive the least squares equation.

Stopwatch being used by different people?
Q. I am doing a research write up, and the method involved different people using a stopwatch to time people in different tasks. I am aware of the negatives of this (such as observational errors) though I was sure there had been some research which suggested that these flaws do not have a significant impact on results. Does any one know of the research or any other research article I could use as a reference to read more about this? I also believe there is a statistical test you can do to measure whether the different people using the stopwatch has had any effect - does any one know anything about that? Thank you in advance.

Why does Earth have a moon and why is it so big?
Q. I just read a quote from a scientist called Irwin I.Shapiro who works at the Harvard Smithsonian Centre for astrophysics. He said,"Looking at all the anomaly's and unanswered questions regarding the Moon, the best explanation for the Moon is observational error, it doesn't exist" Irwin I.Shapiro is a respected figure in astrophysics, his research includes using gravitational lenses to assess the age of the universe. A planet of our size with such a low gravitational field shouldn't have such a big moon, it's seems unique to us. When we look at other planets with satellites, they are much bigger than Earth, with a much stronger gravitational pull and their moons are much smaller to them in comparison.

A. Agreed. The moon is not the type of natural satellite one would expect for a planet the size of Earth. The theory that I have heard, and I believe is currently held, is that the early Earth was hit by another planetary body billions of years ago. The event threw massive amounts of material into orbit enabling the formation of the moon, which was originally much closer to the Earth in its orbit. This is probably a very rare event in the formation of stellar systems, at least, our solar system. We should also recognize the profound significance of our moon in supporting the evolution of intelligent life on this planet. The moon is a fantastic stabilizer of the Earth, limiting wild and frequent shifts in our planetary axis, thus allowing… [cont.]

Need Consult on Concentration Difficulties..?
Q. I've been having trouble concentrating lately, and it is getting progressively worse. Symptoms seem to be extreme short term memory loss (example- walk into a room and forget what I'm doing, all the time), very poor observational skills (not noticing I'm pulling out of a parking spot in front of someone), difficulty registering what people are saying/ what I'm reading, and I make many typing errors, even right now.

Asked by Nikki - Tue May 20 00:42:32 2008 - Astronomy & Space - 1 Answers - 1 Comments

A. These questions are a great bit of background to the modern Lambda-CDM cosmological model. The first question deals with galactic rotation curves, which provide some of the most intuitive, compelling evidence for dark matter. Consider Newton's formulation of gravity: F = G m1 m2 / r^2 where F is the gravitational force, m1 and m2 are the masses of the two bodies, r is the distance between them, and G is a constant. You can see that as distance increases, the strength of the force of gravity decreases. This is a familiar result, and it agrees 100% well with experiments here on Earth. Now consider our galaxy: just as gravity causes the moon to go around the Earth, and the Earth to go around the sun, gravity causes the sun (and all the other… [cont.]
