Re: Mini Black Holes

I'm more for thinking that there's some sort of error in our understanding of physics. Both dark matter and dark energy seem like fudges to make our existing equations work. Seems much more likely that the exist equations are wrong. One reason for suggesting this is that we seem to have made so litt...

Re: Cooling of last sector started! (About quench training)

Thanks for the info. If I recall the 2008 incident was caused by substandard welding on the electrical interconnects and also inadequate pressure release on the helium containment, which blew at least one magnet of it's mounts.

Re: H- ions in the Linac 4: why this is so clever

That is startlingly elegant ! Instead of changing the polarity of the magnet, you change the polarity of the beam. And all you need is a very thin piece of carbon foil (I calculated 1 um from the article): https://accelconf.web.cern.ch/IPAC10/papers/thpeb030.pdf This is the very definition of geniu...

Re: So how’s everyone holding up because of the Coronavirus

The scientist I referred to at the end, wasn't a scientist from the 'incrowd' the minister followed a scientist with a political background. That's why I wrote second last paragraph 'top' scientists. I think you put your finger on the problem here. Politicians like to pick scientists who say the so...

Re: So how’s everyone holding up because of the Coronavirus

Interesting that on the one hand you say the problem is that politicians have been slavishly listening to scientists and then end up giving an example of scientists not being listened to by politicians. I disagree with you heavily. Most of this has been caused by politicians not listening to scienti...

Re: So how’s everyone holding up because of the Coronavirus

I'm doing pretty good. Able to work from home pretty well, only downers are having to cancel a holiday and worse, not having a cricket season.

Beyond that, a lifetime of being anti-social is finally paying off ! I no longer have to avoid people, they avoid me !
