Researchers at NUS just 3D printed metal circuits in mid air using a system called CHARM3D. It uses Field’s metal, a low melting alloy that cools fast enough to hold its own shape. They can literally draw wires in space that conduct electricity, bend, and heal when reheated. A

The smartest age in life may be 55 to 60 – not in your 20s. Raw cognitive abilities, such as processing speed and memory, often peak early in life. Athletes typically hit their prime before 30, mathematicians make major breakthroughs by their mid-30s, and chess champions rarely

I stole this idea and now use it with every single employee. It’s the best illustration I’ve seen of teaching someone to be high agency. It says there are 5 levels of work: Level 1: “There is a problem.” Level 2: “There is a problem, and I’ve found some causes.” Level 3:

So, I went to Knoxville and stumbled upon an insane and awesome new manufacturing approach. A start-up you've never heard of - Perseus Materials - has developed a way to make massive structures out of composites. Full episode down in the comments. You will like.

A group of Spanish and Mexican researchers loaded 25,000 hexagonal dice, each with a side of about half a centimeter, into a transparent cylinder. They then applied different agitation effects to the cylinder to see which one could cause the most effective compaction. Initially

My plan would restore power to the people and restore confidence in our democracy. 74% want Election Day to be a holiday. 75% believe gerrymandering is a major problem. 83% support requiring an ID to vote. Get to work, Congress. Give the people what they want and need.

My pleasure to come on Dwarkesh last week, I thought the questions and conversation were really good. I re-watched the pod just now too. First of all, yes I know, and I'm sorry that I speak so fast :). It's to my detriment because sometimes my speaking thread out-executes my

Bioethanol aus Mais liefert 0.37 l/m2. Ein Benziner fährt damit max. 8 km weit und das ohne Berücksichtigung der Ernte- & der Herstellungsenergie. PV liefert >200 kWh/m2. Ein E-Auto fährt damit >120 km weit. Der Verbrenner ist 20 mal weniger effizient.

If you're making more typos in iOS lately, you're not going crazy - it's a bug in iOS that causes the keyboard to randomly insert the wrong letter instead of what you typed.
