Sodium Batteries Are Coming

Batteries are an increasingly important technology to our civilization. If I could wave a magic wand and make one specific non-medical technology advance 10-20 years in a day, it would be battery technology. Batteries are used in our everyday devices, like phones and laptops…

Lithium is the best salt for battery chemistry because Li is the lightest salt on the periodic table (3 protons). Nothing can ever beat it for theoretical best specific energy (energy storage per mass). Sodium (Na) is right below it at 11 protons, so it’s an obvious choice for a possible Li…

A classified satellite network is emitting a mysterious signal : NPR

An amateur satellite tracker stumbled across the signal which is coming from Starshield satellites in a "hidden" part of the radio spectrum.

It's unclear what the satellite constellation is up to. Starlink, SpaceX's public satellite internet network, operates at much higher frequencies to enable the transmission of broadband data. Starshield, by contrast, is using a much lower frequency range that probably only allows for the…

An Introduction to Multisets

Multisets are sets that allow repetition of elements. As such, multisets pave the way to a number of interesting possibilities of theoretical and applied nature. In the present work, after revising the main aspects of traditional sets, we introduce some of the main concepts and…

Winning with misinformation: New research identifies link between endorsing easily disproven claims and prioritizing symbolic strength

Conversations around misinformation that assume everyone cares about literal truth may be missing the point.

suggests that some people consider it a “win” to lean in to known falsehoods.
The strongest predictor of whether someone believed in COVID-19-related misinformation and risks related to the vaccine was whether they viewed COVID-19 prevention efforts in terms of symbolic strength and weakness. In other words, this group focused on whether an action would make them appear to…

Do You Know What I Know?

Joshua Rothman writes about common knowledge and the book “When Everyone Knows That Everyone Knows . . .,” by Steven Pinker.

Where to begin? Brown bagging is one of those social practices that continues to feel senseless even after it’s been explained.
