Interesting article on an "origami" microscope (see attached).

Researchers have created a high-functioning yet cheap ultracapacitor that is made from two one-atom-thick materials.

The research team mixed "graphene flakes with single-walled carbon nanotubes" to create the groundbreaking device, an American Institute of Physics news release reported.

Ultracapacitors are energy storage devices that can create surges by rapidly releasing the power. By combining the power the energy-density of batteries and the high power-density of capacitors the "ultracapacitor" can provide a boost to devices such as "electric vehicles, handheld electronics, audio systems and more," the news release reported.

This is more of an "engineering in the news" article but still, very interesting:

waitbutwhy.com/2015/06/the-deal-with-solar.html

Here's one of the the take-away pics:



You know that "Mr Fusion" in the sky?  Well in a few hours it drops the same amount of energy on the Earth that the entire world consumes in a year...

This isn't really EPMA related (though I'm thinking hard about some possibilities!), but this talk about tech disruption is quite worth watching I think:

You'll probably want to skip to the 19:53 time stamp in order to skip the introductions.  I admit it's difficult to believe his claims so far as the proposed timelines are concerned, but then again I can't find any fault with his reasoning...  quite interesting!

Just FYI I picked up this little projection telescope a few years ago for my "Weird Science" freshman seminar for a partial eclipse and it worked great for the 2017 total eclipse in the US (see attached- remember to login to see attachments).

It's not inexpensive but great for teaching solar astronomy to students. It's available here:

PS a second attachment shows a bit of the total eclipse group we were with.  Some of you might recognize a few of the people in the pic...

A student in our geology department, David Zakharov, has an interesting blog on petrography called, appropriately enough, "The Petrographer":

He recently wrote some scripts to output chemical maps without Surfer:

Do we get awards for most random places you can get science?  if so, beat this:-

I'd like to point to an article we managed to get in North Korea news.....

https://north-korea.news/news=322240

and this is the pinnacle
https://www.dailystar.co.uk/news/weird-news/668797/mars-science-nasa-aliens-discovery-space-university-of-oxford

boffin, egghead and aliens.....

heres some clown in Radio Sputnik:-

Nice Radio Sputnik interview!

This is not a book review, just a suggestion to read Steven Pinker's new book "Enlightenment Now, which looks at global trends over the last century or so.  I think it's the most interesting and readable non-fiction I've read in many years. 

For some people the worst thing about the book may be be that it contains some good news about global trends, though Pinker is careful to point out that this *does not* mean that we should rest on our laurels or stop working towards a better future. Ocean acidification and changing regional rainfall patterns due to global warming will be a huge challenge, as he is quick to point out.

And I don't agree with everything he says, for example he calls for a rapid increase in nuclear energy to reduce carbon emissions. So while I agree with this statement in principle, in practice I don't think it will be cost effective now and especially in the future. But reasonable people can disagree on this issue, though I suspect $/kWh will decide this ultimately.

Although the book is more focused on global perspectives there is lots of data by country, so here is a graph for some parameters just in the US, which illustrates that one can increase GDP, increase population, decrease carbon intensity and reduce pollution all at the same time:
