+Lawrence Krauss writes about scientists as celebrities. He considers five examples: Einstein, Feynman, Sagan, Hawking, and Tyson; as well as his own experience. Krauss thinks that although public outreach is not necessary for all scientists, and maybe even a bad idea for some, it is important overall. In particular, he seems to suggests that celebrity scientists should use their platform to advocate for social issues and not just popularize science.

I am worried on agreeing with Krauss, because it is too easy for scientists to think they have expertise in areas where they don't and for others to believe them. Here, we should learn from Feyenman, about whom Krauss writes:

"After winning the Nobel Prize, [Feynman] discovered that people, particularly Army generals, sought his advice on many issues, and after beginning to dispense it freely he suddenly realized he was pontificating on issues that he really knew very little about. As a result, he reined himself in."

However, this worry is bittersweet, because I tend to agree with many celebrity scientists on social issues, and so want them to advocate those issues. Even if they are not (the best) qualified to do so.

If you want to get anything done, there are two basic ways to get yourself to do it. The first, more popular and devastatingly wrong option is to try to motivate yourself. The second, somewhat unpo...

So which is it — spiral or elliptical? The answer is neither! NGC 6861, a galaxy discovered in 1826 by the Scottish astronomer James Dunlop, does not belong to either the spiral or the elliptical family of galaxies. It is a lenticular galaxy, a family which has features of both spirals and ellipticals.

Dust lanes are very useful for working out whether we are seeing the galaxy disk edge-on, face-on or, as is the case for NGC 6861, somewhat in the middle. Dust lanes like these are typical of a spiral galaxy. The dust lanes are embedded in a white oval shape, which is made up of huge numbers of stars orbiting the center of the galaxy. This oval is, rather puzzlingly, typical of an elliptical galaxy. The relationships between these three kinds of galaxies are not yet well understood. A lenticular galaxy could be a faded spiral that has run out of gas and lost its arms, or the result of two galaxies merging. Being part of a group increases the chances for galactic mergers, so this could be the case for NGC 6861, which is in the small constellation of Telescopium (The Telescope)..
