Today is the last day of summer*. In my opinion, it is a good time to remember what has happened in the last three months.
* Yes, I know that in some regions it’s already the first day of autumn, but I don’t want to talk about time zones here.
One of the most memorable events was the Pluto flyby. This event had been highly anticipated, not least because some people tend to call this stone a planet. The closest approach happened on July 14th**, and immediately caused a lot of posts in different places. This culminated a series of wonderful achievements in space exploration. In case you didn’t know, the other elements of this series were reaching a comet and throwing a lander on it as well as directing a spacecraft from Vesta to Ceres.
** I believe that Nasa scientists deliberately adjusted the time so that it landed precisely on my birthday.
Another birthday present
On July 14th, Wolfram Research released Mathematica 10.2. If the knowledge of Mathematica is represented by a number from 0 to 1, then my knowledge will be somewhere near 1/Graham’s number. As a consequence, I cannot express an educated opinion about the new release. I can, however, tell you about a less recent project by Wolfram Research, namely this website. The site tries to guess what is contained within a given image, and it does its job pretty well, sometimes even telling the name of a depicted person. I encourage you to try it; it’s a lot of fun.
Scientists at the LHC have discovered a brand new particle. If you want to read a post about it, go here.
Personally, I have completely ran out of interesting news. If you think you know some interesting recent science-related event, leave a comment below.
Anyway, this article would seem incomplete without an unrelated Math problem. Here it is:
The problem. Does there exist a polyhedron P satisfying these conditions:
- Every face of P is a polygon with odd number of sides (triangle, pentagon, etc.).
- P has odd number of faces.
And finally, I’m sorry that the article is somewhat rushed, but the summer is coming to end really fast!
