About Hobab
I'm one of those people who learn through pictures.
I can read a long paragraph about a complicated idea three times and still feel something's missing;
but let someone draw a shape, or let a chart move in front of my eyes, and suddenly everything clicks into place.
My mind is visual. It always has been.
So for a long time I had a simple wish: a place that would show me the big, complicated questions, the ones a two-line definition can't answer.
Not just explain them. Show them!
A place where I could play with an idea, change a number and see what happens, until I really understood it.
The question was what a place like that should look like.
From podcast to blog
My first thought was a podcast. I love telling stories with sound, and I still do.
But here's the thing: a podcast lacks the one thing I needed most. Pictures.
You can't draw a chart in someone's ear!
Then I tried YouTube.
It had pictures, but it was limited in a different way.
You can only watch a video;
the creator sets the pace, the order is fixed,
and the viewer can't reach into what they're seeing and try it for themselves.
In the end I came back to where I started: a blog. The thing a lot of people think has had its day.
But a web page today isn't just text. It can have charts and simulations, and a button the reader presses to see what changes.
Like this one: thin this bubble's film
And readers can stop wherever they like, go back, and move at their own pace.
That's where Hobab started.
Every question that gets stuck in my head becomes an interactive article: a story you can play with, connect with and learn from. And for me, it's a place to put the interesting, exciting things I find.
But why call it Hobab?
Why Hobab
Hobab is Persian for bubble. To me, nothing in this world is certain. Truth is always relative;
something can be true right now, in this very moment, and still not last through time.
With how fast human knowledge is changing, anything that's true today could pop like a bubble in a few seconds and be gone.
Look at history from far enough away and all of human knowledge is the same: something bright and fragile that's still standing, for now,
and on the scale of time, it really does live as long as a bubble.
(If you're curious how a real bubble survives those few seconds, I wrote about it here.)
Every article on this blog is one of those bubbles: what I think is true today, based on the best sources I could find.
Maybe it'll pop tomorrow.
But while it's here, you can look at it up close, see its colors, and ask how it's managed to stay up this long.
