There are a number of reasons why lithium batteries may catastrophically fail and catch fire. Dendrite shorts is one, another reason is poor alignment of the layers during assembly, allowing for eventual shifting of layers leading to intern

I don't think that is very true in this day in age. Here in Cincinnati, the vast majority of houses now have fiber run to them. There are still some stragglers, but that's mainly because slumlord apartment owners don't feel l

This is effectively how hot swapping is done for may modern systems. It seems counter intuitive to call it hot plugging, but it’s what you’ll find if you look up “hot swap controller”.

I believe google/waymo uses Swiss Re for reinsurance, so you are correct.

There are surgical scalpels that are ultrasonic, and they are incredibly sharp when activated. They can cut through skin and tissue like butter!

I had the same experience reading neuromancer in the last year. I felt like I got the vibe of what was going on, but struggled to understand the details and figure out what was actually happening in the story.

Children are one of the high risk populations for flu. That is why kids are a priority of flu vaccines.

Some noise cancelling headphones/earpods can absolutely provide hearing protection, but it does depend. Here are the specs for Apple airpod pro 2: https://www.apple.com/airpods-pro/pdf/Hearing_Protection_dat..

The Android on chip AI is and has been leagues better than what is available on iOS. If anything, I think the upcoming iOS AI update will bring them to a similar level as android/google.

Yes, the iPhone has a laser array and sensor that it uses for lidar.

Waymo's recent experiment with multimodal models and a purely camera based system (EMMA) validate some of the claims that using LIDAR data in training does help. Pretty neat! Still not as good as a LIDAR + RADAR based system.

Google photos is way, way, way better than apple photos at this. It’s not even a competition. I have my sister’s dogs named in my google photos library. Every time I a take a picture of either dog, they are automatically tagged and added to

As an avid mountain biker and having been to bentonville twice, the trails are just ok. Immaculately maintained and there are some neat features, but the hills there are seriously lacking elevation. The small downtown area of bentonville is

Non-fuel uses make up roughly 10% of oil demand. Certainly significant, but unless plastics, fertilizer, etc have absolutely insane growth in the next 25 years, it won't keep demand level.

A Raptor engine has about 1/3 to 1/4 of the thrust of an F-1 engine. However, the Raptor is far more efficient and much more impressive technically. They are really a marvel of modern engineering and science.

On the flip side, I think if they can make slightly more expensive panels with technologies like perovskites, but they are significantly more efficient, they will gain a lot of market share. The solar panels themselves have become an minor

It's fairly common for undergrads and graduate students to compile reviews of research technologies to see what is getting commercialized and what isn't. If you search google scholar or similar for the area you're interested

No, they did not. They promised that they were going to start using a manufacturing technique called dry electrode coating, and they have done that.

Keep in mind you need to multiply those power numbers by capacity factor. Solar in California is at ~29% capacity factor (much higher than I expected honestly), while nuclear is generally around 92%. That is, Diablo Canyon actually puts out

This is basically how USB C became a thing. A group of engineers at Google created the connector design and then gave it to the USB standards body to use as the next gen.

I have been shocked by 110V DC and let me tell you, it hurts. A lot. Would not recommend.

60V DC is the upper limit for circuits that untrained personnel can work on and be exposed to as listed in IEC 62368-1. This is the standard that most consumer goods and IT stuff use to validate and verify electrical safety. 60V isn't

Quanta magazine does a really, really good job with long form science journalism. Highly recommend checking them out.
