Some distraction needed

Man, the news is pretty depressing at the moment, so a few videos in distraction...

First, this one by Arvin Ash is not about anything new, but it's just a good and clear explanation of how new particles are "discovered", but not actually seen, by particle accelerators:

 

Second, I knew that Mt Fuji had accommodation huts way up on the side of the mountain, at which the typical thing is to eat some dinner, get a bit of a sleep, and then continue to the top in time for sunrise. But until I watched the Chris Broad video about his recent ascent, I had no idea that the accommodation was so large, or for that matter, that there was so much built right on the top of the mountain, overlooking the crater. It's pretty amazing, really, and I am unclear as to how all the building material has made its way up there: 

 

And finally: I am surprised to learn that Saudi Arabia has actually started some significant looking excavation work for the absolutely nutty "NEOM" city - "the Line" or whatever it's called.

I also learnt from this video that the country is building a ski resort on top of mountains where it barely snows! 

I can imagine how ecstatic that the architects and engineers must be - money flowing like water to them to draw up the most grandiose of futuristic schemes, but likely confident that they don't have to worry too much about the necessary construction details, given the very high prospects of the most complicated parts never being built.
