2/ The first feature of Roam books, or rBooks for short, is that they allow for non-linear exploration.
Their pages are like Wikipedia pages – they contain links for optional deeper exploration.
Moreover, at the bottom of each page, there is an automatic list of references.
3/ Roam books are still books – they still have a table of content that guides you through your journey of discovery.
However, you can stray off the path or take shortcuts as you please.
4/ Roam helps you see how the arguments connect to each other.
5/ Roam books are editable.
You can add in your own notes or highlight content.
6/ More importantly, with a couple of clicks you can create summary pages that automagically contain all references to the selected concept.
7/ Here's perhaps the most important feature. Roam books can be imported into your own Roam graph! And it will seamlessly link to your pre-existing information.
We've never been closer to "downloading knowledge to your digital brain".
Not only you download info but connections.
8/ So, here is the first Roam book, on ergodicity. Try it! gum.co/ergodicity
9/ Moreover, I already began working on a Roam Book on Team Management.
It takes from my books "Best Practices For Operational Excellence" and "Teams Are Adaptive Systems" and packages them as a Roam Book.
MASKS WORK EVEN IF THE VIRUS IS SMALLER THAN THE HOLES IN THE FABRIC
As a first effect, the virus bounces on the fibers. That's enough to decrease the distance at which it "jumps out". It might even get some of the particles to stuck to the fibers.
(thread, 1/N)
2/ Second, N95 masks also have electrostatic charges that capture particles even if they are smaller than the holes in the fabric.
3/ Third, masks would work even if the virus passed fully through.
They reduce the distance at which it travels after, say, a sneeze. It's as if they introduced additional distance between people.
Moreover, they work both on the way out and on the way in.
6 million Italians should be in home quarantine, only a fraction of them because they tested positive. Most of them are there because tests are few and slow.
Another part of the problem is that enforcing the quarantine & working through the tests backlog is cheaper, easier, and more effective when there are few cases than when there are a lot,
But one would also need the will, capability, and wisdom to do so when it seems less urgent
1/ They don't fully protect you from virus in the air.
Yes, but their point is to prevent as much virus as possible from getting in the air in the first place.
(thread)
2/ There is this Randomized Control Trial I see posted on Twitter which allegedly shows that face masks do not work.
That trial shows that face masks do not protect doctors from patients *that do not wear face masks*.
Such studies do not demonstrate that face masks don't work.
3/ Paradoxically, the more you believe that someone wearing face masks is only partially protected, the more you should want everyone to wear them, so that there is less virus in the air.
In yesterday's tweet, I was critical of scientific institutions endorsing specific parties.
Here is an example of why.
There is no such thing as "the scientific party" or "the anti-scientific one" – not if by science we intend real science, rather than a politicized consensus.
IMHO there's too much focus on who governs the political structure and too little attention to whether:
- The structure is good
- It provides good incentives
- It filters bad members
- The downside of bad decisions is capped
- It provides longevity to the common good or to itself
(I don't live in the US and this was not intended to be a reflection on the US; I merely stumbled on the quoted thread and it made me think. Many other countries will find that, if they remove the words and look at the actions, "scientific parties" aren't that scientific at all.)
Why is it important to care about small HSE violations in manufacturing companies?
Shouldn't we only care about injuries & deaths?
Only if we want the company to fail and workers to die.

2/ Yesterday, I pointed out that a famous automotive company has a lot of OSHA violations. The most common response I got is that those relate to meaningless violations.
Perhaps. But only in a theoretical ideal world, meaningless violations are unrelated to incidents.
3/ In the real world, incidents *approximately* follow a pyramid as the below one (image from my book gum.co/opexbook).
The more "meaningless violations" a company has, the more a big incident is waiting to happen.
