Z's 3-in-3: 5 min a day to live longer • Synthetic brains and Matrix • Pi song

By Zvonimir Fras • Issue #6 • View online

Get 7 extra hours of life for 5 min of work - every day.

Get creeped out by brains.

Listen to a composition based on a number.

This week in 3-in-3 😛

Thing 1: Do this 5 min a day to live longer

If you don’t want to live longer skip to the next thing.

You should eat healthy, exercise, fast, etc… But you know that already.

Yo, Z, I’m busy, just tell me how to avoid all those things and still live longer.

Ok, I got you. Here goes:

Run!

Running 5-10 min daily (Z, did you just casually double the requirements?) makes you 45% less likely to die than if you weren’t.

Cycling or walking makes that just 12%.

It works even if you’re overweight or smoking. (but, you know, don’t)

You want to live longer so you can do you, not to spend that time running.

Good news:

Hour for hour, running gives more time back to people than it consumes.

The study followed 55,000 men and women aged 18 to 100 for 15 years.

Thing 2: Synthetic brains and Matrix

What if AI becomes smarter than us and decides to wipe us out for our own good?

No worries, we’ll just merge with it using brain-computer interfaces. Neuralink and Kernel are already working on it. We’re safe. 🧠

AI entered the chat.

Can I do that too? 👀

Turns out - yes. Brett Kagan and the gang grew human brain cells in a dish, integrated with traditional silicon computing.

Human brain cells in a dish learn to play Pong (1 min)

We often refer to them as living in the Matrix. When they are in the game, they believe they are the paddle.

🧠: What is my purpose?

👩‍⚕️: Your purpose is Pong.

🧠: erm, ok

The DishBrain learns 18x faster than the silicon equivalent.

These results come, at least in part, because of analog computing and you don’t need to use biological material to do that. It will be interesting to see how this evolves.

Thing 3: Pi song

Happy Pi Day!

Geek out alert! Feel free to hop to the video before you forward this to a friend.

If you take a circle with a diameter of 1 and roll it out, you’ll run out of circle when you hit the distance of Pi.

This is what it looks like.

But what does it sound like?

David took the digits, assigned them to keys on the piano, applied some creativity and voila.

You can listen to the 2:21 song bellow 🎧

Song from π!

That’s it for now. Which thing did you like best?

Cheers, Zvonimir

Smart. Entertaining. Helpful. 3 things in 3 minutes.
Because you have things to do.

And reading boring email ain't one of them.

3-in-3 started as a weekly email I blast to a select group of my smart friends. And now you can get in on the action.
