You know I wondered who those guys throwing spears at the busses were. Thought they’d just come doon the watter.
Mitochondria are why I’m a Rare Earther.
In Earth’s history, mitochondrial endosymbiosis occurred once. Without that you don’t have the energy budget for complex life. Moreover, there may be a narrow window where it can happen: modern microbiology has defences and selection pressures that it make inhospitable to the hobbling chimeræ the first mitochondrial cells would have been.
Until mitochondria, the emergence of life from nothing is plausible. With mitochondria, its progression to complex, multicellular and intelligent life makes sense. Both processes in small steps can be replicated, more or less, in the lab. But that one moment is not and has not been. As a result, I think the universe has lots of living slop but very few plants and animals.

I have a chloroplast for you on line two; can you hold?

WWWWH commented on The Triple Failure of 2U, EdX, and Axim classcentral.com/report/2... · Posted by u/raybb
I don't really like how any of the MOOCs run, and I think my issue is that they are not run like universities, they are run like job training centers. They all have the Same courses and the same degrees. Other than a few actual schools like Georgia Tech with OMSCS which actually seems to be trying to innovate to give degrees online at a fraction of the on-campus cost, they also don't seem to be trying to actually give degrees.
A successful MOOC in my mind isn't one that will have some credits for an online certification for programming or nursing that can transfer to a Real school. A successful MOOC is one where I can take a course on Ulysses or Semantics or Mathematics or Plato or whatever just like I could in a real undergrad, but without the same financial and time constraints. I want to be able to spend $5000 taking classes that I find interesting, and accidentally have an English degree Or spend $5000 and really focus and get my degree in X.
Check out the Open University then. It’s the real thing and online. It costs and there are time constraints but they are the experts in remote teaching

author has a book too, I haven't read it but thought I'd link it: https://www.amazon.com/Street-Fighting-Mathematics-Educated-...
It's the same resource--he gives it away for free, but you can buy the book if you want (I did).
Really pleased to have a play with this--I've so often read comments that the agenda, the calendar, on this thing was better than almost anything since, it was interesting to go and have a look. I can see the point, the year view is really good in a way that my current calendar (fantastical) doesn't quite match.
As a reviewer, if I see the authors lie in this way why should I trust anything else in the paper? The only ethical move is to reject immediately.
I acknowledge mistakes and so on are common but this is different league bad behaviour.
