Walkabout the Galaxy
Neptune, Kuiper belt, cosmic rays,
Astrophysics and Astronomy | Physics
Neptune, as the outermost big planet, has an outsized effect on the countless objects in the Kuiper belt in the distant reaches of the solar system. We take a look at how the orbits of Kuiper belt comets today can teach us about Neptune's orbit 4 billion years ago, which is pretty cool if you think about it, and even if you don't. We also get a clue that cosmic rays may come from supernovae, including one in our own galactic back yard. Get all this and top quark trivia on this episode of WtG.
If you've just had a plant-based burger with onions, mustard, pickles, and all the fixins, you might be experiencing halitosis. But if your scientific data illustrates an unusual peaky or flat shape compared to your standard, or should I say normal, Gaussian distribution, then kurtosis is for you. Check out this fourth moment of the distribution of your data to reveal tail extremity. If you're interested in going with the crowd, use the mean and the variants, but if you're exceptional, a true outlier, then kurtosis is for you. Kurtosis, fair and balanced (not).
