I bought an old Nissan Leaf last year. They're actually cheaper than gas cars of the same year. This summer, the weather was nice, I was remote working and I decided to get into a …

I'm gonna be the annoying guy who points out the obvious thats being repeated again and again for the last 50 years... For transport, trains! Trains of different sizes, shapes and …

Not only that, but there are quite a few scientifically sound concepts that escape the tyranny of the rocket equation. Pre-seeded trajectories, particle beam propulsion, sails etc.…

There have been exactly 0 known deadly attacks from wild orcas in history.

Also my recommendation: -Make the card vertical instead of horizontal (phones are held vertically) -Add a +/- bottom on each end of the slider for fine tuning the ppi by 0.1 increm…

Molybdenum and tungsten both have melting point much higher than silicon, Maybe these circuits could be a good candidate for Venus rovers?

A few years ago a popular idea was that our universe existed as an hologram on the surface of a black hole. Recently I saw also a theory that black hole might not, in fact, exist a…

There's an interesting implication to this. We assume that evolution happens when random mutations (similar to random bit flips, removal or injection?) occur and when the random re…

ZBLAN is such a material, a type of glass much more transparent than silica glass and could be used for fiber optics. It has been tested on the ISS. A similar fictional material is…

I think the parent comment exposes the obvious flaw of using plasma to drill: Drilling with diamond bits uses fluid, which is uncompressible. Drilling with plasma uses gas, which i…

You could probably use significantly less coolant if you're using heat pipes. The coolant is mainly gaseous and only a small mass remains liquid during the cycle

Are there any battery that are non toxic if lighted on fire?

Cult member here. I started listening to audiobooks (not this one) about 5 years ago, after a job transfer that meant driving 2 hours a day, in slow traffic, with little attention …

It feels less like a word prediction algorithm and more like a world model compression algorithm. Maybe we tried to create one and accidentaly created the other?

Hundreds of Beavers (2024)

Not sure what functionality is not covered by current cables. Both my laptop and phone, which are several years old, use the usb-C connector for power, data, video, audio, and comb…

I learned to drive with a manual transmission so I'd feel comfortable driving any car in Europe, where manual transmissions are far more common. The transition was stressful but af…

I like to refer to this kind of article when a kid has trouble understanding why they need to provide sources in their homework. Sometimes it's difficult for them to understand tha…

I'm curious about the Aldrin Cycler analysis. Isn't the whole point of the "castle" to house travelers and life support system in a larger habitable space during the long travel, i…

Artemis by Andy Weir dwells a lot on this kind of infrastructure, but I never could understand the orbital mechanics described in the book.

I don't think this result reflects all antibiotic treatments: "RESULTS Oral antibiotic treatment disrupts the colonic mucus barrier" Intraveinous administration may or may not caus…

Heat released by global human energy consumption, every source combined, is insignificant compared by heat received from the sun. (quick calculation 17.7TW / 173PW= 0.01026%). Glob…

Keep in mind that there was nothing indicating that the sun and the stars were of the same nature, or that they were so far away. When you think about it, all stars appear equally …

Here's what I understand of this, correct me if I'm wrong. If 1 kg of matter and 1 kg of antimatter annihilate each other, their entire mass is converted into photons, which are ma…

If your camera app has a manual setting, set a 5 second timer and a 30 seconds exposure, then put it on the floor, face down and camera up. If you want to angle it in a specific di…
